Abstract: A decoy for attracting waterfowl having an upper body portion, a non-parallely oriented keel and an anchor. The decoy body is non-parallely connected to a keel by an attachment means. This attachment means may be fixed or adjustable. This non-parallel orientation between the keel and the upper body allows the decoy to maintain a desired orientation within a body of water when acted upon by a wind or water current. An anchor connected to the combination of the decoy and the keel provides a means for maintaining the decoy in a generally fixed location. This combination of features allows the orientation of a group of decoys to be varied so as to provide a desired natural looking presentation.

Abstract: A carpet strip assembly has a plurality of two-legged or two-pronged staples fixedly secured therein where-in the staples are arranged within an array comprising two or three longitudinally offset rows of staple fasteners. In this manner, the number of fastener points per lineal foot of the carpet strip is increased, as compared to the number of fastener points per lineal foot of a conventional carpet strip by approximately twenty to twenty-five per cent (20-25%). In addition, the cross-sectional configuration of each one of the legs or prongs of each two-pronged or two-legged staple is substantially rectangular such that the resistance to bending forces is effectively enhanced four-fold. Still further, in view of the fact that the two prongs or legs of each staple are integrally connected together by means of a transversely extending bridge or crown portion, pull-out re-sistance of the staples, with respect to the carpet strip, is significantly enhanced.

Patent CA-2423925-A1 (CA)
Title: Variable rate transmission method, transmitter and receiver using the same
Inventor: OHNO KOJI
IPC: H04L12/20
Filed: 1996-02-23
Abstract: A variable rate transmission method that can vary the transmission rate of data. A transmitting side supplies a transmitted data sequence to an error detecting encoder 105 and a frame memory 103. The frame memory 103 stores data of a variable length to be transmitted in one frame. The error detecting encoder 105 calculates an error detecting code (such as CRC code) for each frame of the transmitted data. A multiplexer 104 adds the calculated error detecting code ahead of the transmitted data to place it at the initial position of the frame, and sequentially outputs the data sequence frame by frame. A receiving side calculates an error detecting code of the data in each transmitted frame in the same manner as the transmitting side, and compares the calculated error detecting gode with the error detecting code at the initial position of the frame. The end bit of the frame data is decided as a position at which the two error detecting codes coincide. This makes it possible to transmit variable length data without informing the receiving side of the data length in each frame. This is equivalent that the transmission rate can be varied freely.

Abstract: A downlink telemetry system providing improved apparatus and methods for communicating instructions via pressure pulses from surface equipment to a downhole assembly. The apparatus comprises a surface transmitter (6) for generating pressure pulses, a control system (90), and a downhole receiver (21) for receiving and decoding pulses. In operation, a bypass valve (7) is opened and closed to create a series of pressure pulses received and decoded by a downhole receiver (21). The method significantly reduces the time required for downlink communication without interrupting drilling and without interrupting uplink communications such that simultaneous, bi-directional communication is achievable if the uplink and downlink signals are sent at different frequencies. The telemetry scheme and algorithm provide an inventive method for filtering and decoding the downlink signals. The algorithm determines the time intervals between pulse peaks and decodes the intervals into an instruction. The algorithm also includes error checking for verifying that the instruction was properly received downhole.

Abstract: A SMA actuator (20) having rigid members (21-23) and SMA wires(212, 213), in which improved temperature control of the SMA wires of the actuator is provided by a heat sink, which may be the rigid members themselves, in close proximity to at least a central portion of the wires. Optionally, the heat sink is sized and placed such that the end portions of the wires where they are attached to the rigid members are not in close proximity to the heat sink.  Where the heat sink is external, it optionally has a cooling element that acts passively as a heat sink during the heating cycle of the actuator and that acts as an active cooling element during the cooling cycle of the actuator. An SMA actuator, having a desired contraction limit and a power supply circuit, has a switch in the power supply circuit that is normally closed when the actuator is contracted to less than the desired contraction limit and is opened by the actuator reaching the desired contraction limit. This improved temperature control provides greater cooling of the SMA wires for a faster response and an extended working life of the actuator.
