  • Publication number: 20170307673
    Abstract: An apparatus including a base, a socket, a first switch, a second switch, and an AND gate is provided. The socket is disposed at the base and the socket is configured to receive a plug. The socket has a power end in communication with the first switch and a ground end in communication with the second switch. When a plug is disposed at the socket, the AND gate outputs an alarm signal responsive to the first switch being short when the plug is electrically connected to the power end of the socket and the second switch being open when the plug is electrically disconnected from the ground end of the socket.

  • Publication number: 20170229001
    Abstract: A power distribution unit including a base, at least one socket, and at least one detecting unit is provided. The socket is disposed at the base and has a power end and a ground end. The detecting unit is disposed at the base and comprises at least two switches in communication with an AND gate. Communication between a plug and the socket is detected utilizing the AND gate. A voltage signal is output responsive to the detected communication. More specifically, a first voltage signal is output responsive to detection of receipt of both the power end and the ground end by the socket and/or receipt of the ground end by the socket and absence of the power end. A second voltage signal is output responsive to receipt of the power end by the socket and absence of the ground end.

  • Patent number: 9714972
    Abstract: A power distribution unit including a base, at least one socket, at least one detecting unit and a management unit is provided. The socket is disposed at the base and has at least one power end and a ground end. The detecting unit is disposed at the base. When a plug is disposed at the socket, the detecting unit outputs an alarm signal if the plug is electrically connected to the power end of the socket but the plug is not electrically connected to the ground end of the socket. The management unit is electrically connected to the detecting unit and performs a predetermined operation in response to the alarm signal.

  • Patent number: 9459691
    Abstract: A technique for adjusting a display angle of an electronic apparatus includes capturing, by an image capturing module (of the electronic apparatus), images of a user with respect to a display device (of the electronic apparatus) at a reference first position and a second position. A processing module (of the electronic apparatus) provides an indication when the user exceeds a predetermined threshold in moving from the first position to the second position. A controlling module (of the electronic apparatus) causes a first driving module (of the electronic apparatus) to drive rotation of a first rotating module (of the electronic apparatus) in response to the processing module indicating the displacement has exceeded the predetermined threshold. The first rotating module is coupled to a base unit portion of the electronic apparatus.

  • Publication number: 20160162710
    Abstract: A method of effectuating access security includes sending authentication data with a specific lifetime from a mobile device to an information handling system. The information handling system includes a controller and a housing. The housing includes a chassis and a latch component, with the controller electrically coupled to the latch component. The method includes determining by the controller in accordance with the authentication data whether the mobile device is authorized to activate the latch component and activating the latch component by the controller to lock or unlock the housing in response to a determination that the mobile device is authorized to activate the latch component.

  • Publication number: 20040223333
    Abstract: A continuously adjustable illuminating apparatus includes a base, a light source, a reflector and a continuously adjustable mechanism. The base has a through hole, and the light source movably passes through the through hole and emits light rays. The reflector surrounds the base and is mounted to the base to collect the light rays and reflects the light rays for output. The continuously adjustable mechanism may continuously move the light source so as to continuously adjust a relative position between the light source and the reflector.
