  • Patent number: 11063535
    Abstract: This disclosure describes a method for shorting one or more windings in a steering motor. The method determines that a signal has not been received at a circuit from a processor. The method discharges a first capacitor in the circuit in response to the circuit not receiving the signal from the processor. The method turns on a first plurality of transistors via a resistor in response to discharging the first capacitor. The method turns on a second plurality of transistors in response to turning on the first plurality of transistors. The method sends a short circuit signal from the second plurality of transistors to a steering motor.

  • Patent number: 10931796
    Abstract: The techniques described herein describe diffusing packets through multipath inter-data center networks to identify faulty network apparatuses therein. In an implementation, a method of diffusing packets through a multipath inter-data center network to identify a faulty network apparatus in a source data center is disclosed. The method includes diffusing packets through various paths of a network fabric. Diffusing the packets includes sending out bursts of packets with varying packet header parameters to a set of machines in one or more target data centers. The method further include monitoring packet drops from the bursts of packets, issuing tracerts for each of the packet drops to identify corresponding failed routes, and triangulating the failed routes to identify the faulty network apparatus.

  • Publication number: 20060271321
    Abstract: Disclosed is an actuator having an electronic control module having a port and a controller in communication with the port, as well as software for instructing the controller to detect a calibration signal from the port and transmit an acknowledgment signal to the port. The actuator is placed in a calibration mode by monitoring the port be monitored for the calibration signal. Once it has been determined that the port has received the calibration signal, the actuator will be placed in the calibration mode and an acknowledgment signal will be transmitted to the port.

  • Publication number: 20050057330
    Abstract: An arrangement of a flex circuit relay 7 is provided. The flex circuit relay 7 has a first substrate 10. A first connective member 24 is connected on the first substrate 10. A second flexible substrate 20 is provided having a contact portion 30 spaced away from the first substrate 10 in a first position and being spaced adjacent to the first substrate 10 in a second position. A second conductive member 26 is provided on the second substrate 20 for making contact with the first conductive member 24. A piezoelectric actuator 28 is connected with the second substrate 20 to cause the second substrate contact portion 30 to move between the first and second positions.

  • Patent number: 5808457
    Abstract: An overload protection assembly and method for overload protection of a transistor includes a switching transistor connected between a load at a first terminal and a power source at a second terminal. A measuring circuit measures the voltage levels at the first and second terminals. The first terminal is measured before and after the measurement of the second terminal, and averaged to produce its voltage level. The measured voltage levels from the first and second terminals are subtracted from one another and the difference compared to preset limits to determine overload conditions. If overload conditions exist, the measuring circuit turns off the transistor.
