Abstract: A wafer test probe system, probe card, and method to test back-to-back connected first and second transistors of a wafer. The probe card includes a waveform generator circuit and probe needles to couple the waveform generator circuit to provide a first pulse signal of a first polarity using a body diode of the first transistor to test the second transistor, and to provide a second pulse signal of a second polarity using a body diode of the second transistor to the test the first transistor. One example includes a resistor connected between the waveform generator circuit and one of the probe needles. The probe card includes a probe needle to connect a sense transistor of the wafer to the first transistor during wafer probe testing.

Abstract: A wearable telecommunications device enabling a user to engage in teleconferencing activity from nontraditional locations, while allowing the user free use of his hands. The wearable telecommunications device houses a plurality of input and output devices removably attached to the body of the wearable device. The input and output devices generally include one or more cameras, motion sensors, at least one microphone, and at least one power source. The housing generally consists of wearable headgear such as a helmet. The headgear will have a smaller display near the user's right or left eye, and can also have a larger display mounted on the exterior, whereby others can view information, or the user can view information.
