  • Patent number: 6055654
    Abstract: A test circuit for a memory device having a pair of arrays each of which includes a plurality of memory cells arranged in rows and columns, and a pair of complimentary digit lines being provided for each column of each array. The digit lines are selectively coupled to a pair of I/O lines for each array which are, in turn, coupled to a pair of complimentary data lines. The data lines are coupled to respective inputs of a sense amplifier, one of which is provided for each array. A multiplexer connects the pair of I/O lines for either one of the arrays to the data lines in a normal operating mode. Thus, in the normal operating mode, data is selectively coupled to the inputs of the sense amplifier from the complimentary digit lines for an addressed column. In a test mode, the multiplexer connects an I/O line for one array to one of the data lines and an I/O line for the other array to the other data line.

  • Patent number: 6052631
    Abstract: Computer-based methods and systems for facilitating the inspection of a vehicle to detect the presence of prior damage and problems with previous repair are provided. Exemplary embodiments provide an inspection facilitator, which includes an inspection engine and an inspection interface. The inspection engine and inspection interface are implemented as an expert system, which directs a technician or apparatus to perform a uniform inspection process. The inspection facilitator, after receiving vehicle specific information, first directs and guides an inspection of the underbody of the vehicle to detect gross level damage or repair. The inspection facilitator then dynamically directs and guides an inspection of the outerbody of the vehicle based upon the nonconformities indicated in response to each directed inspection task.

  • Patent number: 6052798
    Abstract: A computer system includes a memory requester that interfaces with a memory module that includes memory portions. An error map that identifies the defective memory portions of the memory module is created and stored in the computer system. Using the error map, a remapping table that maps each of the defective memory portions to a non-defective memory portion in the memory module is created and then stored. In response to receiving from the memory requester a request for access to a requested memory portion of the memory module, a determination is made from the error map whether the requested memory portion is one of the defective memory portions. If the error map indicates that the requested memory portion is one of the defective memory portions, then a determination is made from the remapping table the non-defective memory portion to which the requested memory portion is mapped.

  • Patent number: 6035188
    Abstract: A method and system for actively and rapidly collecting reference waveforms from a large number of cellular telephones is provided. The reference waveforms are used to generate fingerprints which are used to distinguish between authorized cellular telephones and unauthorized cellular telephones. Initially, the system selects a cellular telephone whose reference waveform is desired. The selected cellular telephone is then sent a polling message such as a page or registration request. The cellular telephone receives the polling message and transmits a radio frequency (RF) signal containing a reference waveform that contains certain transmission characteristics unique to the selected cellular telephone. From the received RF signal, the reference waveform is extracted and stored. Preferably, the selected cellular telephone is polled repeatedly in order to receive a sufficiently large number of reference waveforms to be able to generate an accurate fingerprint.

That is, before one-unit poker game is started, an array of five cards are displayed in lateral alignment with one another with four cards placed face up and a fifth card placed face down. The opening/closing frequency or time of a variable prize-winning port 40 is changed in accordance with a prize-winning card set of the poker game. After the one unit poker game is completed, the card array of the five cards is shifted in the lateral direction by one card, and the card at one end and a new card is added and displayed face down at the other end for a subsequent poker game.
