Kiva.org has spent the past 3 1/2 years raising money on the Internet to finance destitute entrepreneurs in 44 impoverished countries. Now in a sign of the economy's spreading despair, the online "microlender" is reaching out to low-income entrepreneurs in the United States
The new publisher of USA Today plans to introduce an electronic replica of the printed newspaper and charge readers for it. The new version will be sent by e-mail to readers beginning Aug. 3 and cost slightly less than printed editions of USA Today, which is the nation's largest newspaper by circulation
Thinking about getting an e-reader but not sure if you like reading the dim screen? An international collaboration of the University of Cincinnati, Sun Chemical, Polymer Vision and Gamma Dynamics has announced Electrofluidic Display Technology (EFD), the first technology to electrically switch the appearance of pigments in a manner that provides visual brilliance equal to conventional printed media.
Providing a resolution of 1 nm at up to 100 m/s, Renishaw's Resolute optical encoder system is capable of 27 bit resolution at up to 36,000 rpm. WIth features such as a jitter of less than 10 nm RMS and a sub-divisional error (SDE) of ±40 nm, the dirt-resistant device suits both linear and angle encoding applications.
With package dimensions of 1.7 mm x 1.7 mm x 0.9 mm, aq family of 3 barometric pressure sensors from Epcos is presented as the smallest device of its type available. The sensor provides air pressure and/or altitude above sea level information for portable electronics such as navigation devices, watches and mobile phones.
Targeting high- and low-side pressure measurements in refrigeration systems as well as environmental test equipment, Kavlico has added the P528 OEM Refrigeration Pressure Sensor with a ¼ SAE Female Flare, Schrader Deflator with 7/16-20 UNF internal threads to its P528 family of sensors. Incorporating ceramic capacitive sensing technology, the device is packaged in a brass or plated-steel housing to endure the high vibration, broad temperature ranges, and high humidity conditions found in refrigeration systems.
Sensortechnics’ CLC Series uses a contact-free capacitive sensor technology to continuously measure the fill level of liquids as well as granular or pulverized materials. The miniature sensor can be mounted to the outside of a container or vessel and is able to measure
Providing remote devices using energy harvesting such as wireless sensor nodes and other micro-systems with onboard power storage, the THINERGY family of thin and flexible micro-energy cell (MEC) products from Infinite Power Solutions provide tens of Watt-hours of energy, equivalent to or more than traditional primary cells that are hundreds of times larger in total volume.
A current of 10 A per contact is possible with the 7-pin RD24 Series 692 over-molded connector cable assemblies by Binder-USA which offers male or female cord sets and straight or right angle connectors. The IP 67-rated device contains a 2-meter PVC UL-approved cable.
The last major TV stations that are still broadcasting in analog will turn those signals off Friday and go all digital. And this time, they really mean it. The original Feb. 17 deadline for the shutdown was delayed by the Obama administration after funding ran out for $40 coupons the government offered to help people buy converter boxes for old TVs.
Featuring a CAT IV rating and Bluetooth communications, Summit Technologies’ PowerSight PS2500, PS3500, and PS4500 handheld power-quality units facilitate wireless operation from a PC or a PDA. Using PowerSight Manager software, the operator can view waveforms, take waveform snapshots and save data while keeping a safe distance from the meter.
Using the I²C and SPI buses, the Freescale MPL115A digital pressure sensor communicates to the embedded system MCU in HDD systems to provide pressure information to optimize the pickup head ride height and maximize the performance and max capacity of the disk.
Columbia Tech, a US-based contract manufacturer, today announced its partnership with Massachusetts-based Owl Power to manufacture the company’s Vegawatt cogeneration system.
Discera has expanded its PureSilicon product offering to include industrial temperature ranges with ±50 ppm and ± 25ppm frequency stability. These MEMS oscillators are pin-compatible with popular crystal oscillators and have low operating current specs (3 mA typ. at 40 MHz), while consuming 1 µA in standby mode.
Offered in 1, 3, and 5 watt packages, the HLD Series by Stackpole Electronics is a four-terminal current sensing resistor with an open design, allowing heat dissipation into the air and lowering board temperatures. The HLD is capable of tolerances of 1 percent and TCR’s of 50 ppm.
