Abstract: A probe burn resistant interface apparatus and method for testing an electronic device use a probe made of a shape memory alloy which upon overheating of the probe during functionality testing of an electronic device contracts the probe to disengage the probe from a contact electrically connected to the electronic device and stop current flow through the probe. Upon cooling of the probe, engagement of the probe with the contact is reestablished. The probe in an example embodiment is a wire which has a core made of a shape memory alloy and a layer of a highly elastic metal, for example copper, on an outer surface of the core to aid return of the probe from its contracted state to its initial state upon cooling an overheated probe for reestablishing electrical connection of the probe with the electronic device being tested.

Abstract: Second digital information serving as copyright protection information can be stably and reliably read without any effect of a defect or pit missing on a disk-shaped recording medium. Second digital information is recorded onto a disk-shaped recording medium by wobbling a pit sequence recorded as a first signal. The second digital information is recorded so that a plurality of bits constituting the second digital information are allocated in a unit period of an identical sync signal contained in the first signal. During playback, the plurality of bits constituting the recorded second digital information are read a plurality of times every unit period of the sync signal, and information of the read bits is then integrated. Thus, information from a large number of wobbled pits across unit periods of a plurality of sync signals can be integrated to determine the bit values.

Abstract: A test apparatus and method of testing a DUT are described. The apparatus includes a receiver and transmitter path each having a pair of switches that switch between a bypass position and a direct position. The bypass position is used for low frequency signals communicated through the apparatus. The direct position allows higher frequency signals to be double converted by upconversion to an IF signal and bandpass filtered before being downconverted to a predetermined frequency. Both variable and fixed LO signals are used to convert the double converted signals so that the same IF may be used independent of the higher frequency signal received or transmitted. Bandpass filtering is applied before and after amplification of the IF signal. Lowpass filtering before and after the double conversion use LPFs of different cutoff frequencies.
