Abstract: A power system includes a first power input, a second power input, a power output, a first ideal diode coupled to the a power input and a power output and a second ideal diode coupled to a second power input and the power output. The power system also includes a first switching circuit coupled to the first power input and the first ideal diode and a second switching circuit coupled to the second power input and the second ideal diode, the switching circuits operating as an open or a short circuit based on an input. The power system also includes a test controller coupled to the first switching circuit, the second switching circuit and the power output and configured to determine an operating status of the power system based on an input to the first switch, inputs to the second switch and the power output.

Abstract: There is provided a face mask with two eye holes, having a lighting display unit located inside a housing on the front of the forehead area of the mask and having a reflective, transparent sheet attached to the front of the mask between the eye holes and the housing. The reflective, transparent sheet is angled down and away from the front of the mask at an angle of about forty-five degrees. When the lighting display unit is energized two LEDs inside the housing, one above each eye hole of the mask, aim their light downward at the top front surface of the reflective, transparent sheet where it is reflected away from the front of the mask in a reverse heads up display operation. A viewer looking at the front of the mask sees what appears to be a pair of illuminated eyes in the eye holes of the mask. The light from the LEDs may be modified by electronic means or by light filters to change the appearance of the illuminated eyes.

Abstract: Swim goggles comprising first and second substantially rigid frames each having a base portion, an eye lens portion, an inner end portion and an outer end portion. The swim goggles further comprise a bridge for engaging the inner end portions of the first and second frames. The swim goggles further comprise a head strap having first and second end portions having a plurality of tooth portions. The swim goggles further comprise first and second connection mechanisms disposed at the outer end portions of the first and second frames, respectively. Each of the first and second connection mechanisms comprise a strap passage way adapted to receive the first and second end portions of the head strap, respectively. Each of the first and second mechanisms further comprise a unitary resilient pawl comprising a median portion and first and second finger portions having end portions engaged with the base portion at a position adjacent to and below the eye lens portion.

Abstract: An integrated interface integrates a bus repeater and remote terminal into a single interface linking a main bus and an extended bus in a communication system. In one embodiment, the remote terminal communicates directly with the bus repeater to monitor bus repeater operation. By integrating the bus repeater and remote terminal together, the integrated interface can use only one set of input and output components for both the bus repeater and remote terminal, reducing the total number of components in the communication system.
