Abstract: A circuit for coupling a 2- or 4-channel audio deck to 2- or 4-speakers in a car stereo audio system to increase the signal level output without raising the supply voltage or increasing the noise. The circuit comprises unity gain inverting and non-inverting amplifiers each connected in one of four channels, with the outputs combined to provide left and right channel outputs for series connection, respectively, to the left and right channel speakers.

Abstract: A hanger assembly used to support tubing, such as a siphon string, and other tools beneath the surface of a wellbore within casing or production tubing. The assembly includes a setting mechanism having first and second sleeves responsive to increased pressure for moving relative to one another for activating a slip assembly and sealing element. The setting mechanism is connected to reeled tubing by a quick disconnect device defining a passage for permitting fluid flow from the surface of the wellbore to the setting mechanism to provide hydraulic activation. The disconnect device is responsive to increased pressure within the passage for disconnecting the reeled tubing from the setting mechanism.

Abstract: A communication system for simultaneously transmitting data and audio signals via a conventional audio communications channel using perceptual coding techniques is disclosed. In a preferred embodiment, a first artificial neural network (NN) at an encoder monitors an audio channel to detect "opportunities" to insert the data signal such that the inserted signals are masked by the audio signal, as defined by the "perceptual entropy envelope" of the audio signal. Under the control of the first NN a data signal containing, for example, an ID or serial number, is encoded as one or more whitened direct sequence spread spectrum signals and/or a narrowband FSK data signal and transmitted at the time, frequency and level determined by the first NN such that the data signal is masked by the audio signal. The audio signal is combined with the spread spectrum and/or the FSK data signal(s) to form a composite signal, which is transmitted to one or more receiving locations via the audio channel.

Abstract: An apparatus for docking a data processing unit in which a guide plate extends over a portion of the floor of a housing for receiving the bottom of the unit. Two guide members are disposed at the respective ends of the guide plate for receiving corresponding surfaces formed on said unit. Each of the guide members defines a guide surface that increases in size in a direction toward the rear wall for engagement by the corresponding surfaces of the unit to gradually center and lock the unit in the housing as the unit is inserted into the housing.

Abstract: This invention relates generally to the field of baby bottles having disks for sealing the apertures of the baby bottles when the bottles are not in use. More specifically, this invention relates to a particular baby bottle that provides a slot at the base of the baby bottle for temporarily storing a sealing disk.

Abstract: A pressure relief valve including a valve member movable between open and closed positions to control fluid flow. A body member is provided which receives a piston operatively connected to the valve member for operating same. The piston defines a first chamber in the valve body extending above the piston and a second chamber extending below the piston. System fluid is introduced into the chambers and the differential fluid pressure in the chambers applies a loading force to the piston, and therefore to the valve member in its closed position. When the system pressure, and therefore the pressure in the chambers, exceeds a predetermined amount the pressure in one of the chambers is vented, causing the piston to move to an open position and permit opening movement of the valve member.

Abstract: A system for preventing the remote detection and decoding of computer data from RF or conducted signal emissions is disclosed. A simulator is coupled to the computer for emulating signal emissions in order to mask the computer signal emissions. The simulator includes an emulation generator coupled to the computer to radiate signals that fully emulate those radiated by the computer to be protected. The emulated signal emissions are synchronized with the computer signal emissions by a special control unit which receives timing instructions from the computer. A random sequence generator randomizes and convolutes the sequence of the emulated signal emissions so that the composite signal emissions formed by the computer and the simulator cannot be decoded to render meaningful data indicative of that being processed by the computer. The simulator is coupled with a computer to be protected by connection to the I/O interface port of the computer.

Abstract: A well completion system and method in which reeled tubing is connected in the completion string which includes a safety valve and a sliding sleeve valve. A straddle assembly is provided within the sliding sleeve valve for sealing against axial flow of fluid and isolating a lateral fluid flow path. A stinger assembly is provided which is insertable within the straddle assembly and connectable to the reeled tubing to lock the reeled tubing relative to the straddle assembly and the sleeve valve. The sliding sleeve valve functions to selectively control the lateral flow of production fluid into the production string for upward flow through the safety valve and the reeled tubing to the ground surface.

Abstract: A manual control device for selectively actuating one or more switches in a multiswitch system. The device is utilized in cooperation with a video entertainment system, multimedia game device or other type system requiring a hand-actuated control apparatus. The device includes a housing, a plurality of switches disposed in the housing and being actuatable upon engagement, a switch actuator mounted in the housing and a plunger forming with said switch actuator a fulcrum to limit movement of the actuator in a manner to provide selective engagement and actuation of the switches, while permitting simultaneous engagement and actuation of selective pairs of the switches to provide different outputs. The device is operable to actuate switches individually or in adjacent pairs. The device is capable of both direct and tilt methods of operation such that in the tilt method the tilting movement for switch actuation is less than that required in the direct method.

Abstract: An operator work station including a plurality of desk modules located adjacent a wall or walls and defining one or more continuous work surfaces. The modules include a standard desk module, an end, or stand-alone, module and a corner module. An opening is formed through one of the walls in a predetermined relationship with the work surface modules, and a housing for receiving a monitor is pivotally mounted for movement about a vertical axis relative to said opening to adjust the monitor relative to the work surface modules for viewing. The work surface modules can be configured to provide one or more continuous work surfaces along one wall, around a corner and along another wall.

Abstract: A coiled tubing service unit and method for oil and gas wells including a string of components extending above ground in coaxial alignment with said well and including an injector for injecting coiled tubing into the well and a sealing unit for preventing the flow of pressurized oil and gas from the well. The sealing unit is adapted to be disconnected from the string of components and removed from the coaxial alignment to permit a relatively large-diameter tool assembly to be inserted therein. The sealing unit can then be repositioned and connected in the string of components and the coiled tubing can be reinserted into the string, connected to the tool and driven into the well.
