  • Patent number: 10692344
    Abstract: A system that uses smart power cords with integrated sensors and wireless interfaces to manage devices in a facility such as a hotel. Each cord may monitor power delivered to an attached device, and may measure variables such as temperature, humidity, and pressure. It may also act as a gateway to other devices in the vicinity. A central control station may manage the devices in the facility via the smart power cords. Data collected from smart power cords may be analyzed to provide alerts and management reports. Illustrative alerts may warn of attempted theft when a device is unplugged, of environmental conditions that suggest mold risks or HVAC problems, or of a staff member requesting assistance via an emergency alert forwarded through a smart power cord. Locations of smart power cords may be automatically configured using either cooperative or non-cooperative localization based on measurement of signal characteristics such as RSSI.

    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: 7969298
    Abstract: Disclosed is a method and apparatus for reducing inbound interference in a broadband powerline communication system. Data modulated on first and second carrier frequencies is received via respective first and second lines of the powerline system. A characteristic of at least one of the carrier signals (e.g., phase or amplitude) is adjusted at the receiver in order to reduce the effects of inbound interference on the transmission system. The adjustment parameters may be determined by adjusting the parameters, during a period of no data transmission, until the output of a differential receiver is zero.
