  • Electrostatic occupant detection system
    Patent number: 8937478
    Abstract: An electrostatic occupant detection system includes an electrostatic sensor and an electronic control unit. The electronic control unit is switchable between an occupant determination state in which the electronic control unit outputs a sine wave having a constant amplitude and a diagnosis state in which the electronic control unit maintains a voltage of the electrostatic sensor at a constant level. The electronic control unit gradually changes at least one of an amplitude and a frequency of the sine wave either when the electronic control unit switches from the occupant determination state to the diagnosis state and/or when the electronic control unit switches from the diagnosis state to the occupant determination state.

  • System and method for performing scan test
    Patent number: 8935584
    Abstract: A system for performing a scan test on an integrated circuit such as a System on a Chip (SoC) that may be packaged in different package types and with different features enabled includes a bypass-signal generator and a first scan-bypass circuit. The bypass-signal generator generates a first bypass signal based on chip package information. The first bypass signal indicates whether a first scan chain associated with a first non-common circuit block of the SoC is to be bypassed. The first scan chain is bypassed in response to the first bypass signal. By enabling partial scan testing based on package information, unintentional yield loss caused by a full scan test determining an SoC is faulty can be avoided.
