ASTM D257 -
National Technical Systems
These test methods cover direct-current procedures for the measurement of dc insulation resistance,volume resistance, and surface resistance. From such measurements and the geometric dimensions of specimen and electrodes, both volume and surface resistivity of electrical insulating materials can be calculated, as well as the corresponding conductances and conductivities. These test methods are not suitable for use in measuring the electrical resistance/conductance of moderately conductive materials. Use Test Method D4496 to evaluate such materials. This standard describes several general alternative methodologies for measuring resistance (or conductance). Specific materials can be tested most appropriately by using standard ASTM test methods applicable to the specific material that define both voltage stress limits and finite electrification times as well as specimen configuration and electrode geometry. These individual specific test methodologies would be better able to define the precision and bias for the determination.

Renesas Electronics Corp.
Renesas' family of low-side FET drivers are very high-speed matched dual-drivers capable of delivering peak currents of 2.0 amps into highly capacitive loads and excellent at driving large capacitive loads with minimal delay and switching times. The high-speed performance is achieved by means of a proprietary "Turbo-Driver" circuit that speeds up input stages by tapping the wider voltage swing at the output. Improved speed and drive capability are enhanced by matched rise and fall delay times. These matched delays maintain the integrity of input-to-output pulse-widths to reduce timing errors and clock skew problems. This improved performance is accompanied by a 10 fold reduction in supply currents over bipolar drivers, yet without the delay time problems commonly associated with CMOS devices. Dynamic switching losses are minimized with non-overlapped drive techniques.

Series HSP -
Kepco, Inc.
The Kepco HSP series provides mission critical power. HSP comprises a group of twelve models, eight 1000 watt power supplies with outputs from 3.3 volts to 125 volts and four 1500 watt power supplies with outputs from 24 volts to 125 volts. All models feature current-sharing for parallel redundant N+1 operation. Models with the or-ing diode, option R, are capable of hot swapping when plugged into Kepco¹s RA 60 series rack adapter. Models with a digital meter, option M, are also available (see photo, right). A mechanical keying scheme allows the user to define which power supply will plug into a specified slot in the housing. Output voltage and current limit settings are adjustable from the panel and may be remotely adjusted.

SparkFun Electronics
LiPo batteries are a great way to power your projects. They're small, lightweight, and pack a pretty good punch for their size. Unfortunately, even the best batteries eventually run low on power and when they do it's often unexpected (and at the worst time). Don't be caught by surprise next time your board suddenly powers-down! The SparkFun LiPo Fuel Gauge connects your battery to your project and uses a sophisticated algorithm to detect relative state of charge and direct A/D measurement of battery voltage. In other words, it tells your microcontroller how much 'fuel' is left in the tank. The LiPo Fuel Gauge communicates with your project over I2C and an alert pin also tells you when the charge has dropped below a certain percentage.
