Abstract:
The present invention is an innovative system and method for passive diagnosis of dementias. The disclosed invention enables early diagnosis of and assessments of the efficacy of medications for neural disorders which are characterized by progressive linguistic decline and circadian speech-rhythm disturbances. Clinical and psychometric indicators of dementias are automatically identified by longitudinal statistical measurements and track the nature of language change and/or patient audio features change using mathematical methods. According to embodiments of the present invention the disclosed system and method include multi-layer processing units wherein initial processing of the recorded audio data is processed in a local unit. Processed and required raw data is also transferred to a central unit which performs in-depth analysis of the audio data. The combined analysis enables the identification of the frequencies and nature of temporary relapses of linguistic decline, and provides essential data for diagnosing early stages of different types of dementias.
Abstract:
A bidirectional direct sequence spread spectrum half-duplex RF modem that can be applied to transmit and receive numerous types of analog and digital pulse modulation. The modem incorporates a SAW based correlator for performing the spreading and de-spreading functions in the transmitter and receiver. A SAW resonator fabricated on the same monolithic substrate provides the frequency source for the oscillator. An upconverter/downconverter provides frequency translation to the desired frequency band. Pulse gating and interrogating pulse shaping are employed to reduce the spectral side bands of the transmitted spread pulse. The RF modem operates as an analog or digital pulse transmitter and receiver. It is adapted to be generic and is versatile enough to be used in many different types of data communication systems, such as OOK, PWM and PPM. The RF modem can be used as the physical (PHY) layer in a layered communication system such as the ISO OSI communication stack. In an alternative embodiment, the transmission bit rate is increased by using a plurality of correlators wherein each is configured with a unique function (i.e., code) that is orthogonal with all other functions.
Abstract:
The present invention is a new and innovative system and method for the stream transmission of video data. The disclosed invention enables a significant reduction in latency and in start decoding and displaying parameters in the transmission of the video data in comparison with existing stream video transmission methods. According to the some embodiments of the present invention each frame or each field is sliced into a predetermined number of slices. Each slice is compressed separately, using standard video compression technologies. The compressed slices are then compounded together before being transmitted over the communication network. On the receiving end the frame is reassembled and decompressed. Finally the frame is recomposed accordingly and filtered to provide a high quality video image.

Abstract:
An internal combustion engine with fuel injection is supplied with a portion of fuel injected at ambient temperature into a cracking reactor chamber also receiving air and, is heated by waste heat from a conventional engine component operating normally, to sustain cracking of the injected fuel so that a cracked and gasified fuel mixed with the air is output as a continuous fuel-air stream at no greater than ambient temperature to the engine intake. The fuel portion is diverted from a conventional fuel supply from a single tank or fed from an additional tank of alternative fuel. The component emitting waste heat is engine coolant or the exhaust manifold, according to fuel volatility. Alternatively, a first tubular section of the reactor with injectors can be mounted on the intake of a conventional turbocharger which supplies the heat sustaining cracking and forms, in effect, a second section of the reactor chamber.
Abstract:
A fuel-air mixing device for installation preferably between an intake manifold and air intake duct of a cylinder of an internal combustion engine. The device extends downstream into the air intake duct, and has an open inlet end for channeling the air-fuel mixture into the device. A closed downstream end forces the air-fuel mixture to flow into the downstream end of the intake duct via special apertures which are adapted to atomise the fuel and mix the same with air. The arrangement ensures that the air-fuel mixture is urged towards the along the walls of the air intake duct, thereby vaporising the fuel by thermal contact therewith.
