Patent number: 9329579Abstract: A wireless sensor device includes a processor connected to a wireless transmitter and at least one sensor, and a power source connected to power the processor and the wireless transmitter. The processor has two or more states. An internal control element senses at least one predetermined condition. The internal control element switches the processor between states based on the occurrence of at least one predetermined condition. A molded body encloses at least the processor, the wireless transmitter, and the internal control sensor. The internal control sensor is physically isolated within the molded body.Type: GrantFiled: February 17, 2011Date of Patent: May 3, 2016Assignee: Scanimetrics Inc.Inventors: Steven Slupsky, Christopher V. Sellathamby, Brian Moore

Publication number: 20150276805Abstract: A method and apparatus are provided for transmission/reception of signals between automatic test equipment (ATE) and a device under test (DUT). A probe card has a plurality of associated proximate active probe integrated circuits (APIC) connected to a plurality of probes. Each APIC interfaces with one or more test interface points on the DUT through probes. Each APIC receives and processes signals communicated between the ATE and the DUT. Low information content signals transmitted from the ATE are processed into high information content signals for transmission to the probe immediately adjacent the APIC, and high information content or time critical signals received by the APIC from the DUT are transmitted as low information content signals to the ATE. Because the APIC is immediately adjacent the probe there is minimum loss or distortion of the information in the signal from the DUT.Type: ApplicationFiled: January 5, 2015Publication date: October 1, 2015Inventors: Steven SLUPSKY, Brian MOORE, Christopher V.
