  • Patent number: 5857192
    Abstract: A quality control system (104) comprises at least one test system (107) and a host computer (122) having a database (130), coupled via a communication link (124). The test system (107) interfaces (120) with a product (118) and obtains its product identifier. The test system (107) outputs, to the host computer (122), an empty file named for the product identifier and a label indicating the type of data to request. The host computer (122), responsive to reading the file name of the empty file, queries the database (130) according to the product identifier and the label. The host computer (122) renames the empty file according to the requested data retrieved via the query. The test system (107), responsive to reading the renamed empty file, tests the product (118) according to the requested data.

  • Patent number: 5842122
    Abstract: A dual mode cellular cordless portable radiotelephone preferentially selects the cordless base station over the cellular system when in range of the cordless base station. When the cordless cellular portable is operating in the cellular mode, the radio channel associated with the cordless base station is sampled for a predetermined time. When a signal on the sampled cordless base station channel is detected, the cordless portable moves to the cordless mode and remains in the cordless mode for as long as the signal quality of the signal on the cordless base station channel exceeds a predetermined value.

  • Patent number: 5787577
    Abstract: A method for adjusting an electronic part template corresponding to an electronic part that is to be placed on a substrate includes capturing an image of the electronic part, calculating a dimension of the electronic part from the image, and adjusting the electronic part template according to the dimension. This dynamic adjustment of the electronic part template helps to reduce excessive rejection rates due to slight mechanical differences among functionally equivalent electronic parts supplied by different suppliers.

  • Patent number: 5745848
    Abstract: An apparatus for eliminating interference caused by spurious signals includes a reference oscillator (127) and a controller (114). Circuitry (500) in a communication device (104) incorporating the apparatus operates at a rate set by a system clock signal (CLOCK). The communication device (104) communicates on any one of a plurality of different channels. The reference oscillator (127) outputs the system clock signal (CLOCK) at a first frequency which generates spurious signals on at least one of the plurality of different channels. The controller (114) shifts the system clock signal (CLOCK) by a first predetermined amount to a second frequency when the communication device (104) is to be tuned to the at least one of the plurality of different channels so as to remove the spurious signals from the at least one of the plurality of different channels.
