  • Patent number: 7733722
    Abstract: Apparatus implements effective testing of a sense amplifier for an eFuse without having to program or blow the eFuse. After initial processing of the sense amplifier, testing determines whether the sense amplifier can generate a valid “0” and “1” before programming the eFuse. A first precharge device and a second precharge device that normally respectively precharge a true sense node and a complement sense node to a high voltage are driven separately. For testing, one of the precharge devices is conditionally held off to insure the sense amplifier results in a “0” and “1”. This allows the testing of the sense amplifier devices as well as down stream connected devices. Once testing is complete, both precharge devices are controlled in tandem.

  • Publication number: 20100027182
    Abstract: A protection device for protecting an electrical installation, which protection device is designed to be connected in parallel with the electrical installation and includes at least two electrically conductive contact members (3, 4) that are suitable for going from a closed position to an open position when a current (I) of magnitude greater than a predetermined threshold value passes through the protection device (1), said protection device being characterized in that, in the closed position, the contact members are separated from each other by a potentially insulating piece (15), thereby forming a spark gap (E) for protecting from voltage surges between the contact members (3, 4). The invention also relates to apparatus for protecting electrical installations.

  • Publication number: 20080250290
    Abstract: A method and apparatus for loading a ring of non-scan latches for a logic built-in self-test. A logic built-in self-test value is loaded into a scannable latch from the logic built-in self-test. An override control signal is asserted in response to loading the logic built-in self-test value into the scannable latch. A non-scan latch is forced to load the logic built-in self-test value from the scannable latch in response to asserting the override control signal. Logic paths in the ring of non-scan latches are exercised. The non-scan latch is part of the logical paths. The test results are captured from the logic paths and the test results are compared against expected test results to determine if the logic paths within the ring of non-scan latches are functioning properly.

  • Patent number: 5852653
    Abstract: A device and method for securing terminal equipment connected to a communications line is disclosed. The device, when inserted into the communications line between the caller and terminal equipment, places an air gap in the communications line physically preventing unauthorized callers from accessing the equipment. The device employs an authentication line separate from the communications path that is used to authenticate the caller wishing to use the terminal equipment. The caller must first call the authentication line where the information regarding the source of the caller is retrieved and stored. Once the caller's source is identified, the device answers the line and requires that the caller enter an authentication code. If a proper authentication code is entered, the device disconnects the authentication line and waits a predetermined amount of time for a call on the communications line.
