Title: Minimizing the turn on time for a receiver operating in a discontinuous receive mode
Inventor: CONNELL LAWRENCE EDWIN
IPC: H04B1/16
Filed: 1995-07-18
Abstract: A receiver 104 operating in a discontinuous receive mode in response to an ON/OFF command 132 receives a modulated input signal and provides a received signal 120 coupled to receiver circuitry 105 which yields an output signal, and in order to minimize receiver turn on time a controller 110 provides a control signal 130 to the circuitry 105 for adjusting the value of a parameter of the output signal, responsive to a value of the parameter of the received signal 120, during the times when the receiver 104 is on, and for holding the value of the parameter of the output signal, responsive to the value of the parameter of the received signal 120, at times when the receiver 104 is off. The parameter may be DC bias, phase, frequency or amplitude. The receiver circuitry may include an AC coupler 106 controlled in the above manner to adjust and hold a parameter of its output 122 and a demodulator 108 similarly controlled to adjust and hold a parameter of its recovered data clock output 124. The rate of adjusting the parameter by circuitry 105 is characterized as bandwidth and the controller causes the circuitry to have a first bandwidth when the receiver 104 is on and a second bandwidth when the receiver 104 is off, the first bandwidth being controlled in dependence on the duration that receiver 104 is turned on so causing the time average of the first and second bandwidths to have a desired value. The time at which the receiver 104 is turned on may precede the time at which desired data is expected to be received by an interval which is dependent on the duration of the previous turn off period, such interval being shorter the shorter the turn off period, thereby saving power source energy. The receiver may be part of a cellular phone, pager, portable data terminal, or personal digital assistant or notebook. <IMAGE>

Patent GB-2307888-A (GB)
Title: Bicycle with low centre of gravity
Inventor: SEARLE RUSSELL JOHN
IPC: B62K3/06
Filed: 1995-12-07
Abstract: A bicycle has a relaxed riding position in which the excursion of the pedals extends forwards of the steering hand grips B, allowing a lower and safer seat position consistent with the legs being fully extended. The feet in their forward position overlap the diameter of the front wheel, the steering inclination being such to reduce the sideways excursion of the front wheel. To allow a relaxed steering position for the arms, the steering members pass to the side of the legs when the steering is turned. As the pedaling torque reaction has a greater horizontal component than the conventional bicycle, a thrust supporting belt is also proposed (fig.4) which disengages when the rider dismounts. Means are also proposed by which the bicycle may be folded wherein the steering members pass to each side of the rear wheel. Handlebar grips B may be ovoid or spherical in shape. The bicycle may have awaiting electric propulsion.

Title: Foot-operated cursor control
Inventor: ROBERTSON NIGEL KEITH BOUCHIER
IPC: G06F3/033
Filed: 1996-03-20
Abstract: Two pedals are used together to control a computer cursor. A Sensitivity Pedal (Pedal 2) varies the sensitivity (speed of movement) of the cursor and a Movement Pedal (Pedal 1 ) determines the direction of movement. By using both feet dynamically together, greater speed and precision is possible than with one foot alone. Cursor movements can be achieved which are both fast and precise, yet are still within the comfortable range of foot movement, by starting with maximum sensitivity then reducing the sensitivity as the target position is approached. Mouse-clicks are generated by rotational movement of the Sensitivity Pedal. Pedal movement may be sensed by electromagnetic induction, a linear voltage transducer, a potentiometer, or an optical transmission transducer.

Title: Transmitting data during voice pauses in a synchronous communication system
Inventor: LEEPER DAVID G
IPC: H04B7/185
Filed: 1996-07-31
Abstract: A communication system 10, having dynamic nodes such as satellites 12, requires narrow-tolerance communication parameters such as timing and frequency. A voice subscriber unit 26 establishes a traffic channel 17 by negotiating communication parameters. A user of voice subscriber unit 26 generates inherent voice pauses in communications. When a data subscriber unit 31 has a small amount of data (known as a datagrain) for delivery through the communication system 10, instead of negotiating a dedicated traffic channel for delivery of the datagram, data subscriber unit 31 monitors an active voice subscriber unit 26 and determines if the communication parameters used by voice subscriber unit 26 are compatible for data subscriber unit 31. Data subscriber unit 31, upon detecting a voice pause by voice subscriber unit 26, transmits the datagram to satellite 12 using the negotiated communication parameters of voice subscriber unit 26.

Patent GB-2315665-A (GB)
Title: Collision detection device
Inventor: INOUE TAKASHI
IPC: H01H35/14
Filed: 1997-07-28
Abstract: A collision detection device (100) designed to have arbitrary operational characteristics has a weight (3), which consists of an eccentric mass (32) which determines the eccentric mass moment of the weight and a metallic plate (31) which determines the moment of inertia of the weight without varying the eccentric mass moment. The weight is pivoted by a shaft (2) at a position eccentric from the mass barycenter to have a prescribed swing velocity and frequency response. A rotor (6) having a first and second cams (61, 62) is fixed to the weight, and leaf springs (4, 5) having contacts (41, 51) are provided to stand on a base (8), with their ends exerting a resilient force to the cams. The weight is pressed by the springs in the b-direction to come in contact with the inner wall of a housing (7). When the acceleration caused by the impact of collision acts on the weight in the A-direction, it swings in the a-direction against the spring force, and bounces on a stopper (16) to swing back in the b-direction. The rotor which swings together with the weight causes the contacts on the springs to close at a certain swing angle, producing a collision detection signal.

Patent GB-2322590-A (GB)
Title: Filtering screen and support frame therefor
Inventor: COOK GORDON JAMES
IPC: B29C/
Filed: 1998-02-25
Abstract: A method of constructing a frame for a filtering screen from a polymer material is described in which a wire frame reinforcement is wholly encapsulated during the frame moulding process so that two parallel spaced apart wires extend through each of the intersecting orthogonal ribs which define the open area of the frame across which the wirecloths are stretched. The wire frame is formed from ordinary mild steel and is separated from the stainless steel woven wirecloth by a sufficient thickness of polymer plastics material to prevent corrosion or electrolytic action. The rigidity of the frame is enhanced by the two parallel reinforcing wires which extend through each of the orthogonal ribs, one near the upper and the other near the lower edge of each rib, so as to form a beam-like assembly. The surfaces of the frame in which the wirecloths are embedded are formed with ridges and the crests of the latter extend to different heights. The crests are softened by heating during the manufacturing process and the wirecloths stretched over the frame are forced into the softened crests after which the assembly is allowed to cool and cure. By tensioning the wires in the wirecloth before they become embedded in the polymer frame, the desired tensions, possibly different in different layers of wirecloth, can be obtained and maintained. The frame is reusable by stripping wirecloths from the top of the frame and fitting fresh wirecloths over the plastics material and heating the regions which are to encapsulate the fresh wirecloth. In a preferred refurbishment method the crests are reinstated by additional plastics material in a refurbishment process before fresh wirecloth is attached to the frame. By forming male and female ends to the frames, and pushing one into the other, so a sealing joint is formed between two similarly constructed frames located end to end.
