摘要： A micro-relay replaces electromechanical and solid-state opto-isolated relays in a computer network. The micro relay is an integrated circuit containing several bus switches in parallel. Each bus switch can make or break a connection. The bus switch is an n-channel MOS transistor with the source and drain connected to different network busses. A bus enable input causes the connection to be made or broken. The bus enable input is separately buffered for each gate of each MOS transistor to prevent crosstalk between bus switches. Since the MOS transistor stops conducting when the source is at a voltage level of the power-supply voltage minus the threshold voltage, a boosted voltage is applied to the gate of the MOS transistor to allow conduction even when the source is at the power-supply voltage level. The boosted voltage is generated by a charge pump. A substrate bias is applied to the transistors to prevent crosstalk from undershoots. Buffers for the gates of the bus switches are inverters that are connected to the boosted voltage rather than the power supply, and to the substrate voltage rather than ground. Thus the gates are driven to the boosted voltage or to the substrate voltage. For reduced crosstalk when the connection is broken, two transistors in series are used for each bus switch, with the intermediate node being pulled to ground when the bus switch is disabled, shielding the two transistors and the two network busses on opposite sides of the bus switch. An external capacitor is used to reduce noise from the charge pump.

摘要： A method provides for a first network node in a plurality of network nodes to transmit a data packet to a hub. The hub and the network nodes are interconnected within a local network system. Control signals are exchanged between the first network node and the hub. The exchange of control signals is done in a first signal frequency range. A data packet is sent from the first network node to the hub. The data packet is sent using data signals within a second signal frequency range. The first signal frequency range and the second signal frequency range do not overlap.

摘要： An electronic device includes an illuminable indicator, a presence detector, and a controller. The illuminable indicator is to indicate information to a user of the electronic device by one or more of being illuminated and not being illuminated. The presence detector is to detect presence of the user in proximity to the electronic device regardless of whether the user is moving or is stationary. Absence of the user is inferred upon the presence detector not detecting the presence of the user. The controller is to enable the illuminable indicator based at least on the presence of the user as detected by the presence detector and to disable the illuminable indictor based at least on the absence of the user. Enablement of the illuminable indicator does not mean that the illuminable indicator is necessarily illuminated. Disablement of the illuminable indicator means that the illuminable indicator is never illuminated while disabled.
