High Frequency Current Transformers
-
Osborne High Frequency Current Transformers operate at frequencies higher than 50/60 Hertz. Their purpose is to reduce high frequency system currents to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when high frequency current transformers are to be used for power measuring applications.

Spectral Response SystemsQuantum Efficiency SystemsIPCE Measurement Systems
-
QE system provides electronics and software designed for fully automated measurement of external quantum efficiency of solar cells. All systems include probes and a fixed plate sample stage for samples up to 150 mm x 150 mm. The main system components include: custom designed software, measurement electronics, and computer system (Windows 8 operating system). The measurement involves focusing monochromatic light to a spot on the device under test, then accurately measuring the photon flux and current from the test cell. The system utilizes a dual beam configuration with lock-in detection, providing an absolute accuracy of ±3%. The QE system uses a grating monochrometer with silicon/InGaAs/Ge detectors. The system includes automatic order sorting filters and two light sources for monochromatic illumination (a Xenon- arc lamp and a halogen lamp). A single lock-in amplifier is used to measure both the reference detector and test device. The main system comes with all the hardware needed to measure quantum efficiency, a fixed plate sample stage and probes.

Information System Technologies Inc.
ISTI offers a new detection system to the facility security and safety industry to quickly neutralize an active shooter and more quickly secure and protect occupants. When confronted with an active shooter situation first responders and safety personnel face immediate tactical disadvantages. Beyond rushing towards ensuing chaos, 9-1-1 calls and eye witness reports are often disjointed, inaccurate, and lack precise location information required to make real time responsive decisions as they arrive on scene. Likewise within the building, the crisis triggers panic and chaotic scrambles towards exits and assumed safe havens. However unorganized and uniformed retreats may actually be leading evacuees back into harm’s way.
