  • Patent number: 10814787
    Abstract: The vehicle-sider rear-view mirror mounted bird deterrent system delivers an electric shock to scare birds away. The bird deterrent system includes a shock strip, a sensor, a microcontroller, a power source, and a vehicle-side rear-view mirror. The vehicle-side rear-view mirror can be any rear-view mirror of a commercial or passenger vehicle. The shock strip is a thin flexible strip that attaches onto an exterior face of the vehicle-side rear-view mirror. The shock strip is positioned along the side rear-view mirror and covers most of the flat surface which the bird is likely to stand on. The sensor is operatively connected to the shock strip, wherein the sensor transmits a signal to the microcontroller when it detects a bird standing on the shock strip. The microcontroller completes a circuit between the power source and the shock strip, thereby creating a flow of electrical current capable of delivering an electrical shock.

  • Patent number: 10770883
    Abstract: Devices having one primary transistor, or a plurality of primary transistors in parallel, protect electrical circuits from overcurrent conditions. Optionally, the devices have only two terminals and require no auxiliary power to operate. In those devices, the voltage drop across the device provides the electrical energy to power the device. A third or fourth terminal can appear in further devices, allowing additional overcurrent and overvoltage monitoring opportunities. Autocatalytic voltage conversion allows certain devices to rapidly limit or block nascent overcurrents.

  • Patent number: 10734179
    Abstract: A method and an apparatus for controlling a circuit breaker in an electrical energy supply network. A switching signal is generated by a protective or control device of the energy supply network and the switching signal is transmitted to a control unit of the circuit breaker. The control unit is caused to open the switching contacts of the circuit breaker upon reception of the switching signal. In order to ensure a switching operation which is as fast as possible even in those energy supply networks in which phases of the current to be switched by a circuit breaker which are free of zero crossings can occur, a current flowing through the circuit breaker is recorded and is checked for the occurrence of zero crossings. The transmission of the signal for opening the switching contacts is prevented until at least one zero crossing has been detected.
