A path redundant, hardware efficient communications interconnect (1) has embodiments that can present true any-to-any interconnect capability for first and second pathways (2) and (3) and can utilize double throw switches (25) with or without single throw switches (24) perhaps in staged collectives of sub arrays (4), (5), (6), (9), and (10). A loop-back communications interconnect (22) can be accomplished by an interleaved sub array (26). A quadrilateral center stage sub array (21) can be combined with asymmetric side stage sub arrays for hardware savings that are tenths of a percent of a traditional interconnect and even present eight fold savings over prior reduced hardware interconnects.

Techniques are provided for simultaneously ascertaining the status of a plurality of devices coupled to a data bus. A master device transmits at least one status request message over the data bus to a plurality of slave devices. In response, the plurality of slave devices transmit to the master device a status indicator message including a plurality of status indicators indicating statuses of the plurality of slave devices. The master device receives the status indicator message and ascertains the status of at least some of the plurality of slave devices by examining the status indicators. The status request message and/or status indicator message may be a message defined according to a protocol associated with the data bus. The data bus may, for example, be a serial data bus such as an I2C bus.

An active protection circuit for a MOSFET isolated switched power supply system operates to control the switching of the MOSFET isolation switches. A monitoring circuit operates to sense and turn off the isolation switch of the currently active power supply if it senses reverse current flowing through the switch. Simultaneously, a controller receives indication that the active power supply is out of specification, and actively switches the system voltage source to the other power supply. The controller actively ensures that the isolation switch of the out-of-specification power supply remains off until it determines otherwise.

A system and method for injecting and canceling a bias voltage in an attenuated circuit is presented. The attenuated circuit is disposed within a tri-state logic-level measurement apparatus. The bias voltage is provided to ensure that when the measurement apparatus is floating, it floats at the tri-state voltage. In one embodiment, a summing network is connected to an attenuator, a first voltage generator which provides a bias voltage and a second voltage generator which provides a cancellation voltage. In another embodiment, a FET amplifier is provided in place of the summing network.

A low power high efficiency power supply provides a high voltage level output, which can be used to drive a variety of devices. The power supply uses controlled feedback to a comparator, which in turn drives an AND gate logic device. The comparator drives the AND gate logic device to gate an input clock signal the output of the AND gate logic being supplied to a resonant circuit that is at or near the resonant frequency of the input clock signal. The output of the resonant circuit is rectified to provide the final voltage output. The final voltage output is attenuated and supplied as feedback to the comparator.
