The device, method, and system embodiments described in this disclosure (i.e., the teachings of this disclosure) enable an authorization circuit having at least one authorization mechanism to cooperate with an access circuit having at least one key mechanism. Upon successfully authorizing at least one datum communicated from the key mechanism of the access circuit, the authorization circuit is arranged to deliver power having determined characteristics to the access circuit. In at least one embodiment, the authorization circuit is arranged as a circuit wired or wirelessly coupled to a power infrastructure in a building. In at least one embodiment, the access circuit is arranged as a smart power plug arranged to temporarily deliver power to a mobile computing device or other electrically powered device. In some cases, power is only delivered after a user consumes certain multimedia information. In some cases, power that is delivered is delivered for only a short time and is measured.

A streaming media device includes a printed circuit board hosting components configured to access internet data. An audio/visual connector is linked to the printed circuit board, wherein the audio/visual connector is adapted for connection to an audio/visual device, wherein the audio/visual connector is adapted to operate with a first audio/visual interface having sufficient power to fully operate the printed circuit board and a second audio/visual interface having insufficient power to fully operate the printed circuit board. A power connector is linked to the printed circuit board, wherein the power connector selectively receives power based on the audio/visual connector utilizing one of the first audio/visual interface and the second audio/visual interface.

Inter-device communication with a pulse-amplitude modulation (PAM) signal can have at least two data eyes with different Vref levels. A physical interface (PHY) can be trained for the PAM signal by training a first data eye separately from the second data eye. The training can include adjusting the first Vref level separately from the second Vref level to center each reference voltage on its respective data eye.

According to one embodiment, an automatic transfer switch (ATS) module for an electronic rack includes a container and four pairs of relays that are disposed within the container, each pair having a first relay connected in series with a second relay. A first two pairs of relays are arranged to connect to a first power source and are arranged to connect to a power supply unit, and a second two pairs of relays are arranged to connect to a second power source and are arranged to connect to the power supply unit. The four pairs of relays are arranged in one of several open-closed configurations, such that in a first open-closed configuration the first source connects to the power supply unit through a first two pairs of relays and in a second open-closed configuration the second source connects to the power supply unit through a second two pairs of relays.

The present invention discloses a USB signal output circuit having reverse current prevention mechanism. A switch circuit turns on when a switch control terminal receives a first high level voltage to output a signal from a signal input terminal to a signal output terminal. A first voltage pull-low circuit includes a passive-component high-pass filter circuit and a discharging circuit. The passive-component high-pass filter circuit couples an output terminal voltage of the signal output terminal to a pull-low control terminal. The discharging circuit turns on when a voltage of the pull-low control terminal is larger than a predetermined voltage level to discharge the switch control terminal to pull the switch control terminal to a second high level voltage. A second voltage pull-low circuit pulls the switch control terminal to a low level voltage when the output terminal voltage is larger than a reference voltage and does not have a glitch.
