Should shoppers turn off their smartphones when they hit the mall? Or does having them on lead to better sales or shorter lines at the cash register? Retailers are using mobile-based technology to track shoppers' movements at some malls and stores. The companies collecting the information say it's anonymous....
T-Mobile is allowing people who participate in its $10-a-month Jump program to upgrade their phones anytime, eliminating the previous limit of two upgrades a year. As introduced last summer, Jump participants get insurance to cover loss and damage, plus the right to upgrade before fully paying off the phone in installments over two years.
The Navy’s Laser Weapon System (LaWS) uses the Phalanx Close in Weapon System’s (CIWS) radar track to obtain a target and combines six high-energy laser into a focused beam of light. While the laser uses a mere 30 kilowatts per volley — a few dollars a shot — the weapon is hampered by inclement weather and other adverse conditions.
Sci-Fi geeks rejoice — the U.S. Navy’s shipboard laser weapon will deploy this summer. *Cue John Williams soundtrack* But the Laser Weapon System (LaWS) — while dirt-cheap to operate — is hamstrung by Mother Nature: Inclement weather — plus a host of other conditions — could limit its effectiveness. Bummer....
Advanced Power Electronics Corp. (San Jose, CA) has recently launched new N-channel enhancement-mode power MOSFETs offering a fast switching performance and very low on-resistance. The AP99T03GS-HF-3 MOSFET comes in a TO-263 package.
Richardson RFPD (LaFox, IL) today announces availability and full design support capabilities for a large portfolio of high-isolation DC-to-DC converters from RECOM Power, Inc. (RECOM). Designed specifically for insulated-gate bipolar transistor (IGBT) systems, the converters' asymmetric outputs of +15V and -9V make them ideal to power IGBT drivers, replacing the need for two converters.
Manufacturing companies build their reputation on the quality and safety of their products. Serious design faults, manufacturing errors and even incorrect labelling often result in widely publicised product recalls, which carry the risk of unwelcome commercial and brand image fall-out.

The new Climatherm range of Air to Air heat exchangers from Marlow is said to bring increased heat power transfer while remaining within the industry standard footprint. Using Thermo Electrics at its core, these compact and modern designs give
POSITAL-FRABA’s (Hamilton, NJ) IXARC encoders combine the accuracy and dynamic response of optical encoders with the ruggedness and compact form factor of magnetic encoders. Building on the company’s
On Tuesday, President Obama announced new fuel-efficiency standards for heavy duty trucks that would take effect by March 2016. These would come on top of existing standards for 2014-2018 model years. While heavy duty trucks make up just 4% of the nation's vehicles, they emit about 20% of the pollutants spewed into the population by the transportation sector.
Ohmite Manufacturing (Arlington Heights, IL) adds a new non-inductive option to their Maxi-Mox series of thick-film axial terminal resistors. This alternative to the standard configuration is ideal for high frequency applications and controls. Features include a resistance range of 250 ohms to 1 Teraohm.
Ledzworld (Amsterdam, The Netherlands) announced it has added an ultra-dimmable AR-111 LED lamp to its product line — the world’s first true retrofit sized premium 850 lumen, single light source AR-111 LED lamp. Features include CRI of 80 and a 25 degree or optional 40 degree beam angle.
Larson Electronics (Kemp, TX) has released a new 6000 watt extendable light tower. This portable light tower is equipped with four 1,500 watt metal halide lamps that produce 575,000 lumens of light. The WAL-C-4XM Quadpod Mini Light Tower is adjustable from seven to fourteen feet.
NK Technologies (San Jose, CA) introduces APT Series Power Transducers. The APT measures three phases of current and voltage and produces an industry standard analog signal proportional to the watts used. The monitor uses current transformers to measure the amperes, and the line voltage connects directly to the transducer, up to 600 VAC.
Linear Technology Corporation (Milpitas, CA) announces the LTC3784, a high-power, two-phase, single-output synchronous step-up DC/DC controller that replaces rectifying boost diodes with high efficiency N-channel MOSFETs. This device can produce a 24V output at 10A from a 12V input at up to 97% efficiency without any heat sink.
Several Powerex (Youngwood, PA) SiC Modules have now been certified RoHS (Restriction of Use of Hazardous Substances) compliant. RoHS regulations ban new electrical or electronic equipment containing more than agreed upon levels of specific substances, including lead....
Yon Bike Lamp is a hi-tech tracker embedded in a bicycle taillight. Enabled by Telit’s GL865-QUAD, the Yon Bike Lamp communicates over GSM/GPRS and over SMS allowing a user to login via a website or from and Android or IPhone app and obtains information about the bike, including its riding statistics. With the device, it is also possible to
Scientists have created a microbattery that packs twice the energy compared to current microbatteries used to monitor the movements of salmon through rivers in the Pacific Northwest and around the world. The battery, a cylinder just slightly larger than a long grain of rice, is certainly not the world's smallest battery, as engineers have created batteries far tinier than the width of a human hair.
Imagine someone spent months researching new cities to call home using low-resolution images of unidentified skylines. The pictures were taken from several miles away with a camera intended for portraits, and at sunset. From these fuzzy snapshots, that person claims to know the city's air quality, the appearance of its buildings, and how often it rains.
A journalist filed a lawsuit Tuesday alleging that Hartford police officers violated his free-speech rights by questioning his use of a remote-controlled aircraft to record images of a car wreck. Pedro Rivera asked a federal court to weigh in on the appropriate uses for aerial drones....
Meeting the unrelenting demands of tight design schedules will always be a challenge for developers of board-mounted power architectures with point-of-load (POL) DC-DC power modules. As board complexities grow—driving drastic increases in the number of POL power rails—designers must rapidly respond....
