Abstract: A receiver for FSK signals comprises means (10 to 22) for receiving the FSK signals and producing quadrature related first and second frequency down-converted difference signals, means (24,25) for amplitude limiting each of the first and second difference signals to form respectively first and second square wave signals, means (26,27,28,30) for sampling the first and second square wave signals at changes in polarity of the second and first square wave signals, respectively, means (32) for combining said samples and memory means (34), for example a hysteresis circuit (Figure 3 - not shown), responsive to a change in polarity in the combined signal for producing a first substantially constant dc output until the next following change in polarity is detected whereupon a second substantially constant dc output is produced. By using memory means (32,34) rather than a filter as is used in the prior art, reactive components are avoided making it less expensive to integrate and also a fixed level bit slicer can be used.

Abstract: A commercial alternating current power source is provided to a first frequency converting circuit (PC1) through a filter circuit (F) and a reactor (LAC). A high frequency switching power supply circuit (15) of the first frequency converting circuit is switched in response to the commercial alternating current power source to output high frequency power. The high frequency power is transferred to a second frequency converting circuit (PC2) through dielectric materials in capacitors (C1, C2) using electric field thereof as a transfer medium. In the second frequency converting circuit, a rectifying circuit (70) rectifies the high frequency power, so that a charging circuit (72) charges a back-up battery (BT) in response to a rectified output. An inverter 77 included in the second frequency converting circuit is switched to output alternating current power, in response to the output of the first frequency converting circuit when the power source is normal, and in response to the battery when the power source is interrupted, respectively. An isolation barrier 44 of the capacitors isolates the second frequency converting circuit from the first frequency converting circuit, whereby an isolation circuit can be made lighter and more compact.

Abstract: A game of skill or chance playable by several participants remote from each other in conjunction with a common event, such as a computer game, provides the basic format or template of the game on a floppy disk suitable for use with the remote users' personal computers. Then by connection to a mass communications one way channel, such as an FM SCA channel, variations in the game parameters and characteristics are broadcast at the same time to all of the individual remote players. These characteristics both initialize characteristics of the game and when the game is being played, provide updated playing parameters. A score can later be uploaded to the central station by, for example, telephone lines or any other convenient means.

Abstract: A gas generator (10) comprises an impact extruded perforated aluminum housing (12) containing a two-stage gas generator having a perforated bulkhead (18) positioned between the stages. Each stage includes a combustion chamber (14, 16) having an igniter (52, 80) and pyrotechnic charge (56, 82) therein with cooling and filter screens (44, 74) surrounding the combustion chamber. The igniter (52) of the first stage is fired by a squib (94) responsively to an external electrical signal. A rupturable barrier and a ball valve associated with the bulkhead control the flow of gas through the bulkhead and provide mechanical timing for ignition delay in the firing of the second stage after the first stage has been fired, and also provide pressure control after ignition of both stages to prevent repressurizing the first stage. Upon ignition, control of the rise in pressure in the combustion chambers and subsequent breakout of gas to an airbag to be inflated is achieved by rupturable foil barriers (70, 72) and surrounding the first stage combustion chamber (14) and the cooling and filter screens (74) in the second stage, the relative thicknesses of the foil barriers (70, 72) being designed to achieve substantial equilibration of pressure in the first and second stages.

Abstract: A method for derivation of interval velocities from post-migration parts first includes the step (14) of determining the apparent depth and slope of an event. The apparent depth of an event is measured. The travel time of the recorded reflection for a particular offset is determined by ray-tracing through the old model and recorded (16). A trial velocity is assigned to the layer between events in the new model (18). The depth of the reflector is varied up or down until the computed travel time agrees with the measured travel time (22), keeping the source/receiver separation contant. A new velocity for the layer between reflectors is selected (24) for rich the depths at each offset are the same.

Abstract: Disclosed is an exhaust gas recirculation system for an engine having a high compression ratio or with a supercharger. An outside EGR duct connecting the exhaust system (4) to the intake system (3) is provided with a first control valve (22), which has a second outside EGR duct (23) bypassing the first control valve. The second EGR duct has a second EGR control valve (24) and a cooler (25). When the engine exists in an extremely low load state, the first and second control valves are closed to inhibit the outside EGR. In the light load state, the first control valve is opened while the second control valve is closed, thereby allowing recirculation of the EGR gases having high temperature and reducing the pumping loss. In the high load state, the first control valve is being closed while opening the second control valve, thereby increasing a recirculation ratio of EGR gases cooled by the cooler and performing both an improvement of anti-knocking performance and a decrease in pumping loss, as well as reducing the heat load of the exhaust system and within the engine.

Abstract: A motion picture image editing method and in particular, a method for detecting such camera works as zooming and panning motions from a motion picture image stored in video tape or the like. In this method, a motion picture image constituted by a plurality of consecutive picture images on every frame basis, and on time series basis and on the basis of a correlation value for a displacement between the frames at a typical point determined for each of small blocks constituting the motion picture image, a motion vector for each of the small blocks is detected. Then a first motion parameter for estimation of a motion of a camera is generated with use of the motion vector detected at corresponding one of the typical points of first one of the frames. Or the first motion parameter for estimation of the motion of the camera is generated with use of a combination of the motion vector and a position vector at corresponding one of the typical points of a second frame inputted previous by one frame to the first frame. Further, the first motion parameters for the respective frames are found, the found first motion parameters are integrated until an integrated value exceeds a predetermined allowable value, and the integrated value is averaged through an integration period to calculate a second motion parameter for determination of the camera motion for the integration period. Finally, the camera motion is detected on the basis of the second motion parameter.

Abstract: A linear optical fiber waveguide dispenser (10) comprising a linear payout leader holder (15) including an optical fiber waveguide having an unjacketed portion (16) and leader (17) comprising a coiled jacketed portion disposed within a housing (11). The housing (11) has an exit aperture (14) through which the jacketed fiber waveguide protrudes. A fiber optic connector (18) is connected onto the end of the jacketed portion of the waveguide. The linear dispenser (10) accommodates the leader (17) without having to increase the size of the payout helix generated thereby. The linear payout leader holder (15) may be used with a balloon assisted dispenser that has its helix sufficiently dampened to create a linear payout. It allows a strengthened leader (17) to be coiled inside the dispenser (10), an arrangement that would not normally fit into the exit of a conventional linear payout dispenser. Also, in situations where there is the need for the fiber to payout close to the dispenser (10), the linear payout leader holder (15) provides a smooth nonabrasive mechanism to accomplish this. Payouts with a helix as small as four fiber waveguide diameters are achievable using the present invention, and the waveguide is protected during the high stress payout initiation phase. A plurality of single pylon launchers (20a-20d) having dual payout capability are provided and incoporate a payout initiation system with the use of the present invention and a balloon assisted dispenser (10).
