Samsung falters, Apple cleans up in phones

Global smartphone shipments grew 30% annually from 1.0 billion units in 2013 to a record 1.3 billion in 2014 with Android accounting for 81% of shipments, reports Strategy Analytics.

Emerging markets, such as China and Indonesia, drove the industry’s growth last year and are expected to continue to do so, says SA.

One billion Android smartphones were shipped – up from 800,000 units in 2013 – compared to 192.7 million iOS smartphones representing 15% share.

“Microsoft shipped 38.8 million smartphones for a relatively niche 3 percent marketshare worldwide in 2014, ” says SA’s Woody Oh, “Microsoft still lacks multiple major hardware partners to build its phones, while Microsoft’s retail presence in important countries like China remains tiny.”

Q4 saw 375 million smartphone shipments, says Juniper Research.

Samsung shipped an estimated 315 million smartphones in 2014 accounting for 25% of all smartphone shipments, however the company reported its first annual earnings decline in 3 years and Q4 shipments fell 3% to 76 million.

Meanwhile, Apple posted a record quarter of 74.5m iPhone sales, representing q-o-q growth of 90% and y-o-y growth of 46% compared to Q4 2013.

With the demand for iPhones driven by the 6 and 6 Plus models, the company for the first time ever, sold more iPhones in China than in the US.

Despite closing in on Samsung in Q4, Apple had a market share of 15% for the full year in 2014.

Lenovo-Motorola combined is estimated to have shipped over 90m smartphones in 2014, managing to improve its market share to just over 7%.

Microsoft, meanwhile reported a 10.5 million Lumia shipments in Q4 2014, driven by low-cost models.

Huawei improved its market share y-o-y, shipping over 70 million smartphones in 2014, with the Honor line of devices accounting for nearly 28% of the total.

Asymmetric Doherty PA reference design from Cree

Cree, the SiC and GaN specialist, has brought out an asymmetric Doherty PA reference design for the 3.5–3.7GHz band for small cells.

This band is an additional spectrum space intended to complement small cell technology by providing increased wireless system capacity for both licensed wireless carrier services and unlicensed public use, such as WiFi.

Providing 10W average output power and predistortion (DPD) correctability, this Doherty PA design utilises Cree’s 30W CGHV27030S and 15W CGHV27015S GaN HEMT devices, which can operate with either 50V or 28V drain supplies and enable enhanced design flexibility for telecommunications, wideband tactical radio, and radar applications spanning low frequencies to 6GHz.

Cree’s CDPA35045 was evaluated by engineers at Xilinx in a 3.5GHz test radio platform that implemented Xilinx CFR and DPD SmartCOR IP on a Xilinx ZC706 evaluation board featuring the company’s Zynq 7Z045 All Programmable System-on-Chip (APSoC) as the processing engine.

The evaluation proved that this combination of Xilinx Zynq APSoC devices and Cree GaN devices results in efficient, low cost, and low power products that enable full flexibility of control processing and the radio signal.

Consequently, the Cree CDPA35045 asymmetric Doherty PA combined with Xilinx radio signal processing IP is an effective solution for small cell implementation in the 3.5–3.7GHz wireless band.

This combination provides base station designers with a proven design that supports the development of new small cell wireless infrastructure equipment, significantly reducing design time and enabling faster product time to market.

Osram laser chip simplifies fibre optic power

Osram Opto is claiming cleaner laser injection into optical fibres with its most recent laser bar.

The device is 5mm wide and consists of five emitters, each 100μm wide with a 4mm long cavity.

Called SPL BF98-40-5, it creates 976nm infra-red at 3W/mm.mrad at an optical output of 44W.

Lateral divergence is between 6° at 30W (95% of power) and approximately 9.5° at 60W.

“Beam quality of a laser is a crucial factor for coupling laser light into optical fibres,” said Osram. “A brilliant light source greatly simplifies the design of the optical system.”

Electro-optical efficiency is claimed to be 65% at 44W for easier cooling.

According to the firm. Life tests show an output drop under 1% after 4,000 hours producing 65W with 25°C cooling water.

Fibre-coupled diode laser systems are used in the automobile industry for vehicle chassis welding, soldering and coating.

Laser diodes are also used for pumping metal cutting fibre lasers – 976nm is suited to pumping ytterbium-doped fibres in particular.

Development was assisted by the Germany Ministry for Education and Research (BMBF) HEMILAS project.

500W convection-cooled medical-industrial PSU

Typical efficiency of 92% has allowed Excelsys Technologies to design a convention-cooled 500W power supply.

XS500, as it is known, carries dual safety certification: EN60950 2nd Edition for industrial applications and EN60601-1 2nd and 3rd Edition for medical applications, meeting the stringent creepage and clearance requirements.

Input to output isolation is 4kVac and “this can be tested on the complete power supply, simplifying system safety agency approvals”, said Excelsys.

2 MOPP (2 means of patient protection) is provided and leakage is under 300uA making it suitable for use in B (body) and BF (body floating) medical applications.

On top of this, designed to meet MIL810G, XS500 is compliant with SEMI F47 for voltage dips and interruptions as well as compliant with relevant EMC emission and immunity standards. It can withstand input surges of 4kV and has been characterised to MIL461F with an external EMI filter for high-rel and defence use.

Operation is from 90-264Vac and offers nominal outputs of 24V/21A and 48V/10.5A, both of which can be adjusted to to other values via the on-board potentiometer or Vtrim functions.

Control includes: remote on/off, power fail, remote sense and current limit adjust.

Protection includes over-voltage, over-current and over-temperature.

Options include I2C digital comms, OR-ing for N+1 redundancy, and conformal coating and ruggedisation for harsh environments.

Warranty is five years, and dimensions are: 323x128x39mm and 1.1kg

“Typical applications for the XS500 include medical systems such as imaging and blood processing equipment.,” said the Excelsys. “In particular, since no cooling fans are used, the units are ideal for medical systems that stipulate low audible noise specifications. The series also suits industrial, laboratory and hi-rel applications.”

Ancient Earth-size planets found, by a little bit of Essex

University of Birmingham scientists have found a solar system with Earth-sized planets from the dawn of the Galaxy – 11 billion years ago.

They used data from sensors on NASA’s Kepler space telescope, made by E2V of Essex.

Kepler’s telescope stares fixedly at a +/-6° cone of space with the largest NASA image sensor ever, assembled by Ball Aerospace, and consisting of 42 28x55mm back-illuminated CCD arrays made by E2V. Each has 2,200×1,044 27µm pixels responding across visible and near-IR wavelengths (400-850nm).

This sits behind a 0.95m aperture Schmidt telescope with a 1.4m primary mirror – see the Society of Photo-Optical Instrumentation Engineers (SPIE) website for chapter and verse.

Although it is a telescope, it is not used to take pictures. Instead it is used to continuously monitor the intensity of all stars in its field of view above a certain brightness – all 100,000 of them. To improve its photometry, it is deliberately slightly out of focus (by 10arcsecond).

To prevent saturation, charge on the CCDs it read out every 3s and the resulting data is integrated over 30 minutes for each star.

“The instrument has the sensitivity to detect an Earth-size transit of a solar-like (mv=12 G2V) star at 4 sigma in 6.5 hours of integration,” said NASA.

Data is stored on the spacecraft and sent to Earth once per month.

To work out the age of the star, the Birmingham team used asteroseismology – watching pulsations in the intensity of the star that indicate the way seismic waves are resonating around inside it. From this, we are told, the star’s age can be deduced.

The existence and size of planets is deduced from variations of star intensity cause by the planets passing between the star and the CCD array.

Details of the ancient star system (called Kepler-444) have been published in the Astrophysical Journal. The planets are actually said to be between the size between Mercury and Venus.

The pale yellow-orange star is 25% smaller than the Sun and substantially cooler. Its age is estimated at 11.2+/-1.0 billion years, two and a half times older than the Earth.

‘By the time the Earth formed, the planets in this system were already older than our planet is today. We now know that Earth-sized planets have formed throughout most of the Universe’s 13.8 billion year history, which could provide scope for the existence of ancient life in the Galaxy,” said Dr Tiago Campante of Birmingham’s school of physics and astronomy.

According to the Univeristy, the planets orbit in under 10 Earth days, indicating they are close to the star – less than one-tenth Earth’s distance from the Sun.

Kepler is a 3.5 year mission, which could be extended to 6 years.

Toshiba launches two ARM-based microcontrollers

Toshiba has added two ARM Cortex-M4F based TX04 series microcontrollers. Both the TMPM470FDFG and TMPM475FDFG are capable of operating two brushless DC motors simultaneously.

The microcontrollers aim to satisfy demand for more energy efficient motors and incorporate vectoring technology to ensure highly efficient motor control.

The TMPM475FDFG further integrates a CAN (Controller Area Network) controller which is required for use in specialist factory automation systems. Both chips are ideal for a wide range of uses ranging from industrial applications to use in home appliances, such as washing machines, fridges and air-conditioning units.

The TMPM470FDFG and TMPM475FDFG are based upon the ARM Cortex-M4F and can operate at up to 120MHz. They incorporate two modules, each containing a programmable motor drive, 12-bit AD converter and vector engine, ensuring the efficient and simultaneous operation of two brushless DC motors from a single chip.

Housed in a 14mm x 14mm LQFP100 package both the TMPM470FDFG and TMPM475FDFG offer an operating voltage ranging from 4.5 to 5V.

STMicroelectronics reported 2014 sales of $7.4 billion for a net profit of $128 million and Q4 sales of $1.83 billion for a Q4 net profit of $43 million. It expects a 5% drop in revenues in Q1.

2014 revenues were 9.2% lower than 2013 revenues.

CEO Carlo Bozotti said that ST’s main objective for this year was to return to revenue growth. ST had higher revenues 15 years ago than it did last year.

Q4 gross margin was 33.8% which is expected to slip to 33.2% in Q1 because of under-utilised fabs. The 10% operating margin target set for mid-2015 has now been revised to a “mid-term” aspiration.

Easy-mount discharge resistors, made in the UK

Cornwall-based Arcol Resistors has released a wirewound discharge resistor for large capacitors.

Shaped to screw straight onto the capacitor, there are three power ratings in the RW series: 10W (1-15kΩ), 13W(1-2kΩ) and 22W (1-33kΩ), all with ten times overload or over-voltage for 5 seconds.

Operation is over -55 to +200°C, de-rating 80 to 175°C linearly.

Tolerance is ±1% (code F) or ±5% (J), and temperature coefficient is 30 or 100ppm/°C.

Discharge resistors are routinely connected across large value output capacitors found in electrical and electronic equipment which may store dangerous levels of energy after the equipment has been turned off.

“Providing a safe discharge avoids any hazardous conditions when connecting other equipment or during service or repair,” said Arcol.

A second application is for use as balancing resistors to control voltage across series-connected capacitors.

Arcol designs and manufactures its resistors in Cornwall, and has been business since 1952.

Stanford researchers stack carbon nanotubes

Researchers at Stanford University have made stacked carbon nanotube ICs with an average density of 100 carbon nanotubes per micrometer with a current density of up to 122 microamperes per micrometer.

“Now that we have this nanotube that’s on par with conventional silicon,” says researcher H.-S. Philip Wong, “we can think about building high-performance systems.”

The Stanford team grew CNTs on quartz begins with quartz. A layer of gold was deposited on top and then peeled away with thermal tape, taking the CNTs with them.

The nanotubes can then be transferred to the target surface, where the thermal tape is eased off and the gold chemically removed, leaving an array of parallel carbon nanotubes on the surface.

One transfer yields around eight nanotubes per micrometer, as measured perpendicular to the direction that current would flow across the devices.

The deposition process can be repeated more than a dozen times by laying down a gluelike polymer before each successive deposition of carbon nanotubes which prevents the CNTs from sticking to one another.

The Stanford team used the multiple-transfer strategy to create a monolithic 3-D IC.

The team built a crossbar switch—a circuit that can be used to connect different inputs and outputs—out of a layer of silicon, two layers of resistive RAM, and then a layer of carbon nanotube transistors. They were able to build the stack of circuits without raising temperatures above 400 °C, which could damage the transistors.

SEMI b-to-b O.98 for December

The SEMI book-to-bill for December was 0.98.

December bookings were $1.37 billion. The bookings figure is 12.3% higher than the final November 2014 level of $1.22 billion, and is 1.1% lower than the December 2013 order level of $1.38 billion.

The three-month average of worldwide billings in December 2014 was $1.39 billion. The billings figure is 17.0% higher than the final November 2014 level of $1.19 billion, and is 3.1% higher than the December 2013 billings level of $1.35 billion.

“While three-month averages for both bookings and billings increased, billings outpaced bookings slightly, nudging the book-to-bill ratio slightly below parity,” says SEMI CEO Denny McGuirk, “2015 equipment spending is forecast to remain on track for annual growth given the current expectations for the overall semiconductor industry.”

In July the b-to-b was 1.07, in August 1.04, in September 0.94, in October 0.93, in November 1.02 and in December 0.98.

Pico Technology aims PC scope at bench engineers

PicoScope 3000D series PC oscilloscopes have up to 200MHz bandwidth, two or four analogue channels, plus 16 digital channels on the mixed-signal models, and an arbitrary waveform generator.

Maximum real-time sampling rate is 1Gsample/s, memories range from 64 to 512Msample, and PC connection is via USB 3.0.

“Even at 1Gsmple/s, you can capture a 500ms waveform – that’s half a billion samples – while hardware acceleration keeps the display updating smoothly,” said managing director Alan Tong.

For analysing signal bursts separated by long gaps, the 512Msample buffer memory can be segmented to acquire up to 10,000 individual waveform segments of 50,000 samples, with less than 1µs re-arm time between each segment – useful for CAN busses, said the firm.

There is a spectrum analyser mode, and software allows serial bus (I2C, UART/RS232, SPI, CAN, LIN, FlexRay and I2S) decoding, mask limit testing, maths channels and filtering.

Triggers, which are all-digital, include pulse width, interval, window, window pulse width, level dropout, window dropout, runt pulse, variable hysteresis, and logic. Mixed signal variants combine digitised analogue triggers with edge and pattern triggering on the digital inputs.

Screen size and resolution are unrestricted, and depend on the PC connected.

The accompanying PicoScope software now has a fast persistence mode for updates of around 100,000waveform/s, while the math channels have been expanded to include configurable filters.

For those wishing to hook into the software, there is a free SDK (software development kit) with example programs in C#, C++, Excel, LabVIEW and MATLAB, and it can be used with any language that supports C calling conventions.

PicoScope software and the SDK are compatible with Windows (XP to 8), and there are beta versions for Linux, Mac OS X, Beaglebone Black and Raspberry Pi.

Prices range from $576 (two-channel 50MHz) to $2,385 (four-channel 200MHz mixed signal) with probes and a five year warranty.

PicoScopes are made in the UK.

EEVblog #708 – Free Energy BULLSHIT!

Are the laws of physics being bent?

Dave explains why free energy / over unity / quantum vacuum circuits are bullshit. And how to find out what’s really happening here by using basic engineering principles.

Can a bunch of toroids, some wire, and a simple circuit boost converter really generate more power than you put in and power 23 LED’s for 52 hours?

He goes through the claims and debunks them one-by-one.

Explains how the circuit works and then builds up the circuit and takes some measurements to show that the energy can easily come from the battery and not some quantum vacuum.

This is as much a demonstration of basic ballpark system engineering, calculations, and understand, as it is debunking.
