  • Patent number: 7021866
    Abstract: The invention is an article of manufacture that has for its purpose, the anchoring of a pole, tube or rod in sand or other sediments. The principal anchoring element is a broad flange auger having a receptacle mounted on top of the auger for insertion of the bottom portion of the pole, tube, or rod, which is to be supported by the anchoring device. When not in use, and during transport to the location of use, the auger is covered by a tubular sheath, which covers the auger up to the receptacle on top, as a protection against the sharp edges of the auger. When removed from the auger, the sheath is used as a handle for turning the auger by use of a locking system that attaches the sheath or handle to the receptacle at the top of the auger. As the handle turns the auger, the auger penetrates the sediments, providing a stable anchor for the pole, tube, or rod. The round pointed end of the sheath may also be used for creating a starter hole in the beach sand or ground surface to begin the operation of the auger.

  • Patent number: 6005921
    Abstract: A device and method for testing a telephone circuit in which a caller takes advantage of available caller identification information to complete a ringback test without resort to potentially costly and overused toll trunks. The ringback test device is accessed by a caller (subscriber or craftsperson) who may not be aware of the telephone number from which he is calling when the caller completes a call to a telephone number assigned to the device. As the caller is accessing the test device, the test device detects the caller identification available between the first and second rings to identify the caller's telephone number, and answers the call after the second ring. The test device presents the telephone number to the caller, and the test device may thereafter be used to complete a ringback test to the identified telephone number. The caller ID information may also be display-formatted at the test device and provided to a caller's visual display.
