    Abstract: A circuit, a system and/or a method detect a passive electrical connection and/or an active electrical connection between an electrical device and a power supply. An integrity of the electrical connection between the electrical device and the power supply is monitored to determine if the electrical device may have access to power and/or to determine if the electrical device may be secure while on display. A high frequency AC signal is modulated onto a positive power rail between the electrical device and the power supply. Capacitance circuitry of the electrical device may remove the high frequency signal from the positive power rail. An absence of the high frequency signal on the positive power rail indicates that the electrical connection exists between the electrical device and the power supply. A presence of the high frequency signal on the positive power rail indicates that the electrical connection does not exist between the electrical device and the power supply.

  • Patent number: 9007228
    Abstract: An Ethernet-based transmission system using a dying gasp according to the present invention includes an SMPS for supplying power to an Ethernet-based lower level system, detecting a state of a power fault, and outputting a dying gasp alarm signal. A CPU receives the dying gasp alarm signal, and generates and transmits an alarm packet. A PHY chip receives the alarm packet, and uplinks the alarm packet so that the alarm packet is transferred to a higher level stage. An L3 switch receives the alarm packet and determines whether a power fault has occurred in the lower level system. Accordingly, the present invention applies a dying gasp to an Ethernet-based or EPON-based transmission system and is then capable of generating and transmitting an alarm packet so that when a power fault occurs, a device in a higher level network can rapidly determine the occurrence of the power fault.

  • Patent number: 8988234
    Abstract: An alarm system for alarming whenever there is a power leakage from an electronic device, includes a voltage decreasing circuit, a switch circuit and an alarm circuit. The voltage decreasing circuit receives a first voltage from a live wire output terminal and outputs a second voltage. The switch circuit outputs a control signal when the power leakage is detected. The switch circuit is electrically connected to a connection port. The connection port is electrically connected to the live wire output terminal and a neutral wire output terminal. The alarm circuit receives the control signal and alarms. If there is power leakage from the electronic device, the first voltage from the live wire input terminal flows into the ground wire input terminal via the electronic device; the switch circuit turns on and the alarm circuit is closed to alarm.

  • Patent number: 8983785
    Abstract: A method and system for displaying waveforms generated from input signals received at a common input channel (CIC) of a data acquisition (DAQ) device. An input signal received at the CIC can be displayed as a present-time waveform, and while the input signal is displayed as a present-time waveform, the input signal can be tagged for displaying the input signal as a historical waveform for the CIC. After receiving another input signal at the CIC, a display can be refreshed to display, simultaneously, the historical waveform for the CIC and the other input signal as another present-time waveform for the CIC. The DAQ device can tag the displayed input signal in response to a user pushing a selector device on the DAQ device. The display can display other present-time waveforms with the historical waveform to allow a user to compare input signals received at the CIC.
