Patent GB-2285550-A (GB)
Title: Optical coordinate measuring system for large objects
Inventor: GELBART DANIEL
IPC: G01S17/875
Filed: 1994-01-05
Abstract: The system consists of multiple optical transceivers 3, 3a (transmitter-receivers) mounted on the walls of a room 1. The object 2 to be measured is touched with a hand-held measuring probe 4. To measure, the probe triggers the transceivers to read the distance to two retroreflectors (5, 6, Fig. 2) mounted on the probe. The location of the probe tip (11, Fig. 2) is computed from at least six transceiver readings (three for each retroreflector). The distance between the transceivers and retroreflectors is determined by measuring the phase shift of a high frequency modulation superimposed on light beams. To avoid ambiguity two modulation frequencies are used, one for coarse and one for fine resolution; all measuring light beams are generated by a single laser diode (32, Fig. 5) and are detected by a single photodiode (38, Fig. 5), being transmitted to and from the transceivers via optical fibres (30, 36, Fig. 5). The transceivers include a beam steering device to track the position of each retroreflector; to facilitate this each retroreflector includes a light source (7, 8, Fig. 2). <IMAGE>

Title: Dynamically addressable communication
Inventor: BERKMAN WILLIAM H
IPC: H04W88/18
Filed: 1994-01-05
Abstract: A dynamically-addressable communications system 10 provides either a list or set of dynamic addresses to selected receivers 100 for broadcasting information packets from a transmission source 12 to the selected receivers. Each dynamic address provided in the list or set is associated with a particular information packet designated to be received by the particular selected receivers to which that dynamic address is provided. Additionally, each broadcast information packet includes at least one dynamic address identical to the dynamic address provided to its associated selected receivers. Thus, the broadcast information packet which includes such identical dynamic address may be received by its associated selected receivers, which then modify the dynamic address list or set. Preferably, after each selected receiver receives a broadcast information packet, the dynamic address associated with that particular received information packet is removed from the list or set of dynamic addresses provided to that selected receiver at least temporarily. <IMAGE>

Patent GB-2309560-A (GB)
Title: Computer systems
Inventor: PLUMMER WAYNE
IPC: G06F9/445
Filed: 1996-02-09
Abstract: A physical computer system of a first type performs an emulation session in which it emulates a computer system of a second different type and in which an operating system is operating on the emulated computer system. Booting the emulation software and the operating system can take a long time. To reduce this problem, when the emulation session is shut-down, the values of those variables necessary to define the state of the emulated computer system at the start of the shutting-down step are stored. Then, when subsequently starting a emulation session, the values of the variables are restored from the stored values so as the restore the emulated computer system to its state at the start of the preceding shutting-down step. Typically, the storing of the variables during the shutting-down step and the restoring of the variables in the subsequent starting step can be arranged to take far less time than the time to boot-up the operating system from scratch.
