    摘要: An improved method of framing data packets in a direct sequence spread spectrum (DSSS) system that uses one pseudo-noise code (PN-Code) to frame the packet with a start-of-packet (SOP) and end-of-packet (EOP) indicator, and a different PN-Code to encode the data payload. Furthermore, the SOP is represented by the framing PN-Code, and the EOP is represented by the inverse of the framing PN-Code. This method creates a robust framing system that enables a DSSS system to operate with a low threshold of detection, thus maximizing transmission range even in noisy environments. Additionally, the PN-Code used for the SOP and EOP indicators can be used to indicate an acknowledgement response.

    摘要: A modular office system for work stations includes at least one generally planar horizontal work top having a work surface and an opposed under surface. A plurality of legs are attached to the work top by a plurality of leg attachment structures. Each leg attachment structure has a first side which is attached to the under surface of the horizontal work top and a second side which is attached to one of the plurality of legs. A horizontal connection member interconnects the leg attachment structure of one work top to a leg attachment structure of another work top. A vertical connection member is attachable to the leg attachment structure and includes a vertically extending portion for securing a panel thereto. The vertical connection member has a slot for passage of the horizontal connection member therethrough to permit attachment of one work top to another work top with the vertical attachment member attached to the leg attachment structure.

    摘要: Communication circuitry uses a combination of Pseudo-Noise (PN) coded and non-PN coded transmission periods to represent different data values. In one embodiment, a number of data values are encoded into a smaller second number of encoded ternary values. The Pseudo-Noise (PN) codes are transmitted representing some of the encoded ternary values and no transmitted PN codes represent other encoded ternary values. The throughput of spread spectrum radio systems is increased by representing data values in fewer spread spectrum time slots.
