Abstract: An invention is provided for a new and novel intake/exhaust device for an internal combustion engine. A rotating cylinder having an intake/exhaust port penetrating the outer surface of the rotating cylinder and meet at an axis of rotation and have a connective relationship which allows fluid to flow easily. The rotating cylinder when used in a 4-stroke engine aligns the intake port with the combustion chamber, and when rotated will align the exhaust port with the combustion chamber each at the correct time. This novel invention overcomes the limitations of current valve trains by only using rotation, and not by using rotation and linear motion to activate valves thereby allowing the engine to attain much greater RPMs.

Abstract: An indoor geolocation system for determining a location in three-dimensional space includes a plurality of base stations and a mobile device movable about an indoor environment in three dimensions. The mobile device detects electromagnetic signals in the indoor environment emitted by devices other than the base stations, and generates a signal profile based on the signals. The mobile device transmits the signal profile to one or more of the base stations, which forward the signal profile to a remote server. The system determines a location of the in three-dimensional space of the mobile device by comparing the signal profile to data regarding signal profiles at a plurality of locations in the indoor environment. The data regarding signal profiles in the indoor environment may have been captured by a detection device other than the mobile device at a time prior to the detection of the electromagnetic signals by the mobile device.

Abstract: A processor is provided for use with a marking material cartridge the processor having configurable logic for configuring the processor for use with an associated printing device. A print cartridge includes a housing defining a chamber for storing a marking material therein and a circuit on the housing. The circuit includes a memory portion storing data related to the marking material, an interface portion in operative communication with the associated printing device for communicating therewith, and a configurable execution unit including a network of gates which are programmable by first set of instruction primitives received into the circuit to define a first set of operation instructions executable by the execution unit during operation of the print cartridge of the associated printing device.

Abstract: A marking material cartridge for use with associated marking devices is provided. A universal electronic system is provided on a housing holding marking material. The universal electronic system stores first and second sets of configuration data for configuring the cartridge for operation with marking devices of first and second types. A second memory is provided and a control unit is included for selectively copying one of the first or second sets of configuration data from the first memory to the second memory for configuring the cartridge for operation with an associated printer based on identification information received from the printer. Several sets of configuration data are stored in the first memory for selective individual copying to the second memory for configuring the cartridge for use with printers of different types based upon identification information received from the printers.

Abstract: A code-enhanced, multi-user detection, Reduced Algorithm Receiver in a multiuser communication system reduces the signal processing requirements by limiting the number of searches between consecutive symbol cycles using information from an encoder state diagram. The Receiver makes use of a convolutional encoder's state machine properties to mark possible transitions as invalid based on the current state of the multiple users'encoders, thus removing them from the search tree.

Abstract: A cooperative code-enhanced multiuser communications system having a receiver for resolving user ambiguity in a received composite signal by using convolutional encoder state machine properties to analyze strings of bit sums and separate out individual user data. The receiver comprises a signal sampler which converts a received composite signal to a digital data. A single point cluster mapper determines a closest pseudo-constellation point, and the pseudo-constellation point is formed with the aid of power and timing control in the transmitters. A bit sum look-up table maps symbol points to bit sums. A deterministic loop tests for bit sum cases where symbols can be determined immediately. A guess loop tests the bit sum after the deterministic loop test and performs guesses until all bits are decided. The bit sum is provided to a multiuser convolutional decoder to decide all user data streams.

Abstract: A cartridge is provided for use with an associated printing apparatus. The cartridge includes a housing, a semiconductor storage device for storing data, a plurality of contacts for connecting the semiconductor storage device with an associated printing apparatus, and a printed circuit board held in a fixed relationship relative to the cartridge housing. The printed circuit board is rigid or otherwise relatively inflexible and defines a pair of opposite sides. The semiconductor storage device and the plurality of contacts are disposed exclusively on one of the pair of opposite sides of the printed circuit board.

Abstract: A method is disclosed for topical application of compositions containing a chemical additive onto a paper web. The present invention is also directed to paper products formed from the method. In general, the method includes the steps of extruding a composition containing a chemical additive through a melt blown die and then applying the composition to a moving paper web. In one embodiment, the chemical composition is extruded into fibers and applied to the paper web. The chemical composition can contain, for instance, various additives, such as a polysiloxane softener.
