Title: Limb positioning device
Inventor: NAGATOMO YASUAKI
IPC: A63B69/00
Filed: 1998-06-10
Abstract: A combination stance limiting and muscle flexing device particularly useful in karate training. The device consists of a flexible strap which is adjustable in total length, connected at opposite ends by means of swivel connectors with cuff assemblies to be worn on the legs or arms of an individual. The flexible strap is made up of two length-adjustable portions connected by an elastic portion. The length-adjustable portions form loops at their free ends which receive the swivel connectors and are adjusted by folding the strap material over on itself at selected positions along the body of the strap material. The strap material is made of Velcro material which easily attaches and detaches to allow for easy adjustment. The elastic portion of the strap allows a limited stretch capability of about two inches. Once the student's limbs are at the optimum distance and properly positioned as determined by the unstretched length of the flexible strap, he may expand further against the resistance of the elastic, thus flexing the appropriate muscles and joints. The cuff assemblies are worn on the student's wrists or ankles, and have "D" rings providing an attachment point for the swivel connectors at opposite ends of the flexible strap. The cuff assemblies are made up of an outer cuff, preferably constructed of Velcro material, and an inner cushioning liner, preferably made of neoprene rubber and are attached to the respective limb by wrapping around and attaching the outer cuff to itself by means of the Velcro material. The swivel connectors allow for the switching of karate positions while wearing the device without binding.

IPC: H04M1/725
Filed: 1997-02-27
Abstract: A cellular telephone (1) is provided with a connector (7) for conecting it to an interface unit (11). The interface unit (11) can exchange speech and data signals with the telephone (1) as well as providing power. When the telephone (1) is connected to the interface unit (11), its antenna (3) is effectively disabled. The interface unit (11) provides a link between the telephone (1) and a BTS via a communication path other than the cellular telephone system's conventional cell arrangement. The communication path can comprise telephone or ISDN connections, leased lines, point-to-point microwave links or coaxial cable. In the cases of telephone and ISDN lines and leased lines, baseband speech and data signals pass between the telephone (1) and the interface unit (11), and a modem (14) is used to transmit and receive these signals over the communication path. If a microwave link or coaxial cable is used, r.f. speech and data signals may be passed between the telephone and the interface unit (11). A single interface unit may be used to provide connections for a plurality of telephones.

Patent CA-2249260-A1 (CA)
Inventor: HOU VICTOR T
IPC: H04L47/762
Filed: 1997-03-17
Abstract: Bandwidth is adaptively allocated in an upstream channel of a layered data communication network such as that used for carrying messages from a number of subscriber units (250, 252, ..., 254) to a central controller (210), for example, to allow the subscriber units to send data for Internet access, videoconferencing, or voice communication. A running total of unallocated bandwidth (BWA(j)) is maintained in successive control intervals. A traffic count (C(i)) is determined for each subscriber unit by measuring the bandwidth which is used, for example, by counting the number of slots used in a control interval. The assigned bandwidth (B(i)) of the subscriber units is then adjusted when a ratio (K) of the traffic count to the assigned bandwidth is at or below a lower threshold (T1), and the running total of unallocated bandwidth is incremented by the decrease in the assigned bandwidth. The assigned bandwidth may be increased when a ratio (K) of the traffic count to the assigned bandwidth is at or above an upper threshold (T2) by distributing the unallocated bandwidth among the subscriber units. A subscriber unit hierarchy may be used to grant priority to selected users.

Inventor: MAYER RENE W
IPC: E21B47/10
Filed: 1998-10-27
Abstract: A method for determining a volume fraction of water moving in a predetermined direction along a highly inclined conduit. The method includes measuring a fractional volume of water occupying the conduit at a plurality of locations along the conduit. An oxygen activation velocity of the water flowing in the conduit is determined at a plurality of locations along the conduit. A counting rate of a gamma ray detector used to measure oxygen activation is normalized with respect to the measured fractional volume of water. The normalized count rates of the gamma ray detector are characterized with respect to a relative velocity between the water and the detector. The step of characterizing is performed in portions of the conduit which are sloped so that gravity acts on the water along the predetermined direction. A fraction of the characterized counting rate represented by the oxygen activation counting rates measured along the conduit is determined. The fraction represents the fractional volume of water moving in the predetermined direction.
