  • Patent number: 11283214
    Abstract: Described is a power connector device for separating an electrical connection under direct current (DC) voltage or alternating current (AC) voltage between an electrical connector element and an electrical contact element. The power connector device includes the electrical contact element. The electrical contact element has a first conductive part and a second conductive part spaced apart one from the other so as not to be directly electrically conductively connected to one another. The power connector device includes a semiconductor switch for maintaining an electrical connection between the electrical connector element and the electrical contact element during separation of contact between said electrical connector element and said first conductive part to thereby prevent arcing during electrical disengagement of the electrical connector element from the electrical contact element.

  • Patent number: 8985305
    Abstract: A vibration feeding apparatus comprises an alignment track that is operative to receive electronic components and to arrange the electronic components in a desired orientation by vibrating and accelerating the electronic components located on the alignment track. An inspection station rejects electronic components that are not in the desired orientation onto a reject track for reintroduction to the alignment track. A spreading unit adjacent to the alignment track then transfers rejected electronic components from the reject track to the alignment track for arranging the electronic components in the desired orientation.

  • Patent number: 8733539
    Abstract: A vibration feeding apparatus comprises a receptacle for holding and conveying components, and first and second linear motors coupled to the receptacle. The first and second linear motors are spaced from each other and have respective coils that are aligned parallel to each other. The first and second linear motors are operative to be driven at a first operation mode whereby to impart rotary vibration to the receptacle, and at a second operation mode whereby to impart linear vibration to the receptacle.
