Fishermen have known for years that they've had to steam farther and farther from shore to find the cod, haddock and winter flounder that typically fill dinner plates in New England. A new federal study documenting the warming waters of the North Atlantic confirms that they're right...
Chimps, our nearest relative, don't talk. We do. Now scientists have pinpointed a mutation in a gene that might help explain the difference. The mutation seems to have helped humans develop speech and language. It's probably not the only gene involved, but researchers found the gene looks and acts differently in chimps and humans, according to a study published online Wednesday by the journal Nature.
The first touch-screen BlackBerry phone, the Storm, got a few things right, but generally it was a chore to use. Good thing a lot can change in a year. Though not without flaws, the latest version of the device, the BlackBerry Storm2, is the phone Research In Motion Ltd. should have released last year...
STMicroelectronics introduced a single-package analog gyroscope that accurately measures angular rates along three orthogonal axes. The sensor provides 360° angular-rate detection for high-precision 3D gesture and motion recognition in mobile phones, game controllers, personal navigation systems and
Central Semiconductor released CBRSDSH5-40 Schottky bridge rectifier packaged in the SMDIP case. This device is said to be the first surface mount 5 A, 40 V full wave bridge rectifier with a low VF of 0.37 V and an IR of 40 µA. The CBRSDSH5-40 is appropriate for a broad range of solid state lighting and
ITT Interconnect Solutions' BIW Power Cable Connectors can be used to join round and flat cables up to 1 AWG. The connectors purportedly save up to three hours of rig time. Available separately, mid-joint protectors for 4.5", 3.5", 2.875", and 2.375" tubing sizes provide additional mechanical protection.
AVX Corporation has extended the working voltage range of its RF multilayer ceramic capacitor (MLCC) from 100 VDC to 250 VDC. The SQCA Series includes a capacitance range of 0.1 pF to 100 pF in a 0605 case size. Intended applications include microwave RF/IF amplifiers, low noise amplifiers, mixers, oscillators, filter networks, and MRI system applications.
Pittman brand 30 mm brush-commutated DC motors integrate high-energy bonded neodymium magnets for maximized power density and an optimized magnetic field profile and 7-slot straight armature to minimize cogging. The motors feature a large diamond-turned commutator and copper-graphite brushes to deliver
Haydon Kerk Motion Solutions introduced its Haydon IDEA Drive stepper motor linear actuator. The IDEA Drive is an integrated linear actuator, electronic drive, and control unit fully programmable with a patent pending GUI (graphic user interface). Programming the actuator is through
Pickering Interfaces is expanding its range of PXI instrumentation modules with the introduction of the 41-752 Battery Simulator. Developed in association with DMC, this six-cell battery simulator provides up to 300 mA of current from each cell. The output voltage from each cell is fully
Chloride North America announced today that its ManageUPS CIO UPS centralized infrastructure management software is capable of sending email alerts to all mobile devices, providing professionals with remote visibility of key UPS performance measures, regardless of location. IT professionals can now
IOtech has released three new data acquisition modules in the 6000 Series of advanced measurement products. These products combine Ethernet-based DAQ modules with powerful, easy-to-use software. The 6222 is a 12-channel, simultaneously sampled, thermocouple input module. It features
The 600 V H-Series power factor correction (PFC) rectifiers from Qspeed Semiconductor purportedly has the highest switching efficiency of any silicon diode on the market. The H-Series products have a lower QRR temperature coefficient that purportedly minimizes switching losses at higher operating temperatures.
Geotest offers a user-configurable FPGA 3U PXI card that features 160 digital I/O signals for specific application needs. The GX3500 employs the Altera Cyclone III FPGA that supports clock rates up to 150 MHz and features over 55,000 logic elements. According to the company, the GX3500
Amazon's Kindle can read books aloud, but if you're blind it can be difficult to turn that function on without help. Now two universities say they will shun the device until Amazon changes the setup.
