Title: Interactive, computerised gaming system with remote terminals
Inventor: MENASHE JULIAN
IPC: G06F19/00
Filed: 1994-05-18
Granted: 2000-07-18
Abstract: The gaming system includes a host computer, a plurality of general purpose terminal computers forming player stations remote from the host, means for providing communication between each of the terminals and the host. Each terminal has a program for generating screen graphics and sound locally in response to control data packets generated by and received from the host. The host generates random numbers for a game being played on a connected terminal within preset criteria for that game in response to data packets received from the terminal. The data packets are of variable length between 1 and 80 bytes. The host sequentially stores the minimum significant information for replaying a game, auditing and security, such as accounting data of each player at the start of each game, random numbers generated by the host, responses received from a player, and whether a game was completed. Play is substantially real-time, because only minimal data is transmitted with functions requiring large amounts of data, such as screen graphics being generated locally. The statuses of host and terminal are restored automatically on re-establishing communication following an interruption to ensure fairness to players and prevent them defeating the outcome of a game.

Inventor: SCHOLZ MATTHEW T
IPC: A61L15/07
Filed: 1994-01-05
Granted: 2005-07-12
Abstract: The present invention provides an article, comprising: a fabric sheet which has been microcreped; and a curable resin coated onto the fabric sheet. The present invention involves microcreping or compacting a fabric sheet to impart stretchability and conformability to the fabric while minimizing undesirable recovery forces. Suitable fabrics for microcreping are fabrics which comprise fibers which are capable of first being mechanically compacted or "crimped" and then being set or annealed in the crimped, i.e., distorted, state. The article may be in the form of an orthopedic bandage and may optionally contain a plurality of microfiber fillers dispersed into the resin. The incorporation of microfiber fillers into the casting materials of the present invention adds substantially to the strength of the cured casting material, particularly when the fabric used therein is a non-fiberglass fabric, while not detracting from the handling properties of the uncured casting tape.

Abstract: A sunshade mounting bracket assembly for mounting a sunshade to a vehicle without the use of tools or fasteners.  The bracket assembly includes an outer bracket, an inner bracket, and an elbow to which the sunshade is attached.  The outer bracket is  mountable to an apertured panel such as the sheet metal interior roof of the vehicle.  The inner bracket includes resilient locking prongs which define an interior hollow into which the elbow is inserted.  The resilient locking prongs are structured to be insertable into an opening in the outer bracket.  After their insertion into the outer bracket, the prongs engage the outer bracket when the inner bracket is axially rotated relative to the outer bracket from a first rotational orientation to a second rotational orientation for use.  During their engagement with the outer bracket, the prongs are compressed radially inward to compress the elbow maintained within the hollow, which results in rotation of the elbow relative to the inner bracket being frictionally resisted.  A method of installing the bracket assembly to a vehicle is also disclosed.

Abstract: The invention relates to a method and apparatus for linearizing a flow velocity sensor based on pressure difference measurement. According to the method, such a difference of two pressure signals (4, 5) is measured from the flow under measurement that is proportional to the square of the flow velocity, the difference of said two pressure signals (4, 5) is measured using a micromechanically manufactured symmetrical capacitive differential pressure sensor (20) based on the force balance principle, in which sensor the pressure-induced deviation from force balance is compensated for by inducing on the pressure--sensing diaphragm (23) of said differential pressure sensor (20) a force-balance-restoring electrostatic pressure so that the pressure--sensing diaphragm (23) is subjected to the force-balance-restoring electrostatic force, whereby the amplitude of the force-balance--restoring electrical feedback control signal, which also acts as the system output signal, is directly proportional to the square root of said difference of said two pressure signals, and thus, a linear function of the flow velocity. According to the invention, said feedback control voltage depending on the direction of the pressure difference is applied only to either of the stationary electrodes (21 or 22) disposed on the same side relative to the sensing diaphragm so that the electrostatic force of attraction thus induced acts counter to the force generated by the pressure difference under measurement, whereby the polarity of the system output voltage signal is dependent on the direction of the flow.

Granted: 1999-10-05
Abstract: In a first node of an optical network, an OAM (operations, administration and maintenance) controller produces an electrical OAM signal to control an optical cross-connect switch. This OAM signal is converted to an optical OAM signal and optically multiplexed with an optical payload signal associated with an optical path established in the cross-connect switch, producing an optical multiplex signal which is transmitted. A second node of the network demultiplexes the transmitted signal into an optical payload signal and an optical OAM signal, the latter being converted to an electrical OAM signal and used by an OAM controller of the second node for updating the OAM information. The updated OAM information is used to control the optical cross-connect switch of the second node. The demultiplexed optical payload signal is associated with an optical path established in the cross-connect switch of the second node.

Title: Compiler with generic front end and dynamically loadable back ends
Inventor: LIM SWEE BOON
IPC: G06F9/45
Filed: 1996-03-12
Granted: 1999-09-21
Abstract: A system and method provides for variable target outputs from a compiler with only a single execution. The compiler includes a front end, a generic back end, and plurality of individual back ends that are dynamically loaded by the compiler during execution. The front end produces an abstract syntax tree which is then processed by the generic back end and the individual back ends to produce a number of back end trees, each adapted for a specific back end, and representative of the desired structure of the various target outputs, including target code files, or events. The generic back end traverses the abstract syntax tree, and on each node of the tree, invokes each back end that has a node of its back end tree attached thereto. The back end can then modify its own back end tree, and attach further back end nodes to other nodes of the abstract syntax tree. In turn the generic back end will invoke such added attached nodes, until all attached back end nodes on all the nodes of the abstract syntax tree have been processed. This results in completedback end trees for all of the back ends, requiring only a single pass of the front end to produce the abstract syntax tree. The individual back ends then process their respective back end trees to produce their target outputs. A look up operation is provided in the generic back end that returns one or more back end nodes in response to a request therefore specifying a node of the abstract syntax tree, and a family identification value of a back end node.
