  • Patent number: 12065089
    Abstract: Disclosed herein are methods, systems, and devices for assisting programming of vehicles via on-board diagnostics (OBD) ports. In one embodiment, a programming assist device includes a first interface configured to be electrically coupled with an OBD port of a vehicle, power converter circuitry, and a second interface configured to be communicatively coupled with a vehicle diagnostic device. The power converter circuitry is configured for receiving a first voltage signal from a first pin of the first interface and providing a second voltage signal to a second pin of the first interface. The second voltage signal is configured to facilitate a programming mode for the vehicle.

  • Patent number: 9373964
    Abstract: A power converter and a method of operating the same is described, for use in a power conversion system that is capable of receiving power from various sources, including renewable sources, for delivering power to a load. Power type detection circuitry is provided for identifying the type of power source at the input of each power detector, based on attributes of the time-varying power received. The power converter is constructed of a boost stage followed by a galvanically isolated DC-DC converter stage. If a renewable input power source is detected, the boost stage is controlled to operate at a maximum power point, and the DC-DC converter stage is operated in an open loop manner when load exceeds available power at input. The load falls below available input power, the boost stage is controlled to regulate its output voltage and DC-DC converter stage is also placed under closed loop control.

  • Patent number: 9357758
    Abstract: The fish grabbing tool is a device that is designed to grab the side of a fish in situations, such as ice fishing, where the use of a net is inappropriate or cumbersome. The fish grabbing tool positions a first jaw and a second jaw that can be positioned by the head or upper body of the fish. A pull ring is used to operate a grabbing mechanism that secures the first jaw and the second jaw around the fish. The fish grabbing tool comprises a grabbing device, a center post, and a handle.

  • Patent number: 9178359
    Abstract: A power converter and method of operating the same for use in a power conversion system capable of receiving power from various sources, including renewable sources, for application to a load. Power type detection circuitry is provided for identifying the type of power source at the input of each power detector, based on attributes of the time-varying power received. The power converter is constructed of a boost stage followed by a galvanically isolated DC-DC converter stage. If a renewable input power source is detected, the boost stage is controlled to operate at a maximum power point, and the DC-DC converter stage is operated in an open loop manner. If the AC grid is detected as the input power source, the boost stage is controlled to attain maximum power factor, and the DC-DC converter stage is placed under feedback control of the output voltage. Operating modes are also switched in response to low load demand.
