  • Patent number: 7898242
    Abstract: A probe card assembly can include an insert holder configured to hold a probe insert, which can include probes disposed in a particular configuration for probing a device to be tested. The probe card assembly can provide an electrical interface to a tester that can control testing of the device, and while attached to the probe card assembly, the insert holder can hold the probe insert such that the probe insert is electrically connected to electrical paths within the probe card assembly that are part of the interface to the tester. The insert holder can be detached from the probe card assembly. The probe insert of the probe card assembly can be replaced by detaching the insert holder, replacing the probe insert with a new probe insert, and then reattaching the insert holder to the probe card assembly. The probe insert and holder can be integrally formed and comprise a single structure that can be detached from a probe card assembly and replaced with a different probe insert and holder.

  • Patent number: 7269398
    Abstract: An automatic gain control circuit for a receive apparatus for a mobile object which automatically controls the gain of a variable gain amplifier amplifying a received signal from an antenna installed in the mobile object and outputting the amplified signal to the receive apparatus. The circuit comprises an intensity detector that detects an intensity of the received signal; a comparator that compares the detected intensity with first and second threshold voltages; and a controller that outputs a control signal for adjusting the gain to the variable gain amplifier based on the comparing results of the comparator so that the gain of the variable gain amplifier has a hysteresis with respect to the intensity of the received signal.
