    Abstract: A wireless communication system operating in the presence of the periodic noise signals such as from a microwave oven, the communication system, including at least two wireless communication stations with each station including a transceiver, each such transceiver. Each transceiver includes a detector for detecting periodic noise signals and producing a first signal indicating the presence of noise signal's quiescent period and second signals indicating the end of quiescent periods of such periodic noise signal. A controller responsive to the first and second noise signals controls the transceiver to provide effective communication with an other transceiver which minimizes the noise effect of the periodic noise signal. The transceiver transmits information concerning the detected quiescent period for use by the other transceiver to determine when to transmit during such quiescent period.

    Abstract: A fastening element and method that utilizes a fastener or stamping which is capable of forming a fastening assembly by engagement with a self-tapping fastener is disclosed. The fastening element includes one or more indentations formed within a portion of the circumference of an unthreaded bore located within the fastening element. Each indentation has an edge that can have the same helix angle or pitch as the self-tapping fastener that it is to engage to serve as a guide to properly align the fastener within the bore. The indentations also assist formation of mating threads within the element by significantly reducing the required end load to start the tapping process.

    Abstract: An optoelectronic device that provides isolation between a resonant reflector and an adjacent conducting layer of the optoelectronic device. Isolation may be accomplished by providing a buffer or cladding layer between the resonant reflector and the adjacent conducting layer of the optoelectronic device. The cladding or buffer layer is preferably sufficiently thick, or has a sufficiently low refractive index relative to the refractive index of the waveguide of the resonant reflector, to substantially prevent energy in the evanescent tail of the guided mode in the waveguide from entering the adjacent conductive layer of the optoelectronic device.

    Abstract: An apparatus for body surface mapping comprises a plurality of electrodes for attachment to spatially separate locations on a human torso with each electrode capable of detecting the electrical activity associated with a heartbeat and producing a corresponding voltage. The electrodes are sampled at a rate of 1 KHz during a cardiac cycle and sets of sampled values are produced and stored. Positional variations of the maximum and minimum sampled values over time are displayed as a projection of trajectories of the maximum and minimum sampled values in a three dimensional (x, y, t) space onto planes perpendicular to a plane containing the electrodes.
