Abstract: A spread spectrum communications system uses a leaky coaxial cable for cost effective radio communication in enclosed areas. The system includes radio units (12) which communicate with a transceiver, the transceiver being coupled to the leaky coaxial cable (16). Full-duplex communication includes a first frequency band (F1) for transmitting spread spectrum signals from the transceiver to the radio units at power levels which are adjusted to take advantage of the losses associated with leaky coaxial cable, and a second frequency band (F2) for transmitting spread spectrum signals from the radio units to the transceiver at the more conventional spread spectrum power levels specified by the FCC. The present invention employs this split band configuration to accommodate communication over leaky coaxial cable without expensive and bulky filtering for isolation between the transmit and receive signals.

Abstract: A diversity receiver (200) recovers clock information from different versions (301, 302) of a transmitted signal (106). The diversity receiver (200) receives the different version (301, 302), converts the versions (301, 302) into samples (307, 317) via a common sampling clock (309). The receiver (200) the correlates the samples (307, 317) with like synchronization patterns and uses clock information from the received version (307 or 317) which gives the greatest correlation output signal (504,506) for data detection in one of two detectors (323, 326). The choice of detectors (323, 326) is determined by the diversity receiver (200) by counting the total number of bit-differences output by detectors (323, 326) over a predetermined time period and comparing the total bit-differences with a number represented by a threshold signal (330).

Abstract: A passive-type mine roof bolt is constructed of multi-strand steel cable.  The bolt head is constructed of a hexagonal- or other drive-headed collar having an internally tapered funnel-shaped bore therethrough, and a tapered plug having a frusto-conical outer surface that engages the funnel-shaped inner surface of the drive collar.  The tapered plug has an internal bore essentially concentric with the outer frusto-conical surface, and is adapted to fit over the steel cable, the hexagonal head drive collar fitting over the tapered plug such that pressing the tapered plug and steel cable into the inner funnel-shaped bore of the hexagonal-head drive collar causes serrations on the internal bore of the tapered plug to be urged down against, and bite into, the steel cable, resulting in a rigid hexagonal head for the cable bolt.  The tapered plug is in actuality, a pair of essentially identical diametrically opposed semi-frusto-conical tapered sections that more easily compress together to bite into the multi-strand steel cable.  A number of alternative embodiments enhance the bolt's retention strength in the bore hole to aid in stabilizing the rock formation.
