Abstract: An exemplary embodiment is a temperature monitoring buffering sensor and system for applications ranging from food storage to temperature-controlled pharmaceuticals. The system includes a temperature sensor unit with a buffered temperature probe sensor contained in a housing with a Bluetooth® transmitter circuit. The sensor unit is battery operated and is self-contained without the need for wiring to provide power or signal flow. The sensor unit controller periodically sends out a transmitter beacon signal identifying the temperature sensor unit and the temperature sensed by the probe, as well as a battery condition. A base station is positioned close enough to be in range of the transmitter beacon signal and includes an RF receiver circuit configured to receive the RF transmitter beacon signal from the sensor unit, and a processor configured to monitor and analyze data received by the RF receiver circuit.

Abstract: A system and method for coding text data wherein a first group of text data is coded using a Viterbi algorithm using a Hidden Markov model. The Hidden Markov Model computes a probable coding responsive to the first group of text data. A second group of text data is coded using the Viterbi algorithm using a corrected Hidden Markov Model. The Hidden Markov Model is based upon the coding of the first group of text data. Coding the first group of text data includes assigning word concepts to groups of at least one word in the first group of text data and assigning propositions to groups of the assigned word concepts.

Abstract: The present invention provides a processing apparatus and methods for the extraction of user information streams from a composite CDMA waveform. The apparatus and methods increase CDMA system capacity by orthogonalizing an individual user's signal from thermal noise components, multi-access interference, and spatially diverse but non-orthogonal coded components. The present invention exploits both the temporal diversity and the spatial diversity present in the received composite CDMA waveform to increase performance. The smart antenna multiuser detector makes use of blind-block-adaptive nonlinear optimization strategies, which are used to separate user signal components from a composite CDMA waveform by jointly processing in both a chip (code) and spatial domain.

Abstract: An apparatus and method for spread spectrum multiuser communication receivers is disclosed that includes, an adaptive filter adapted to minimize a block error function, wherein the filter tap weights are updated according to a non-linear optimization algorithm adapted for block processing of time-varying data.

Abstract: A system and method for coding text data wherein a Hidden Markov Model is generated responsive to a first group of text data. A second group of text data may then be coded using a Viterbi algorithm or a Sampling Algorithm which is responsive to the generated Hidden Markov Model.
