Abstract: A method of monitoring a patient's compliance with a medication program includes transmitting a first signal from an electronic ingestible medication delivery device located within a patient's body, the signal including information about a physiological parameter of the patient. The signal is detected with an electronic reader located outside the patient's body. A second signal is provided to the reader from a different source than the delivery device. The second signal includes information about the same physiological parameter of the patient. Related systems are also described.

Abstract: Disclosed is a novel circuit able to generate any logic combination possible as a function of the input logic signals. The circuit is described as a 2 input logistic map circuit but may be expanded to 3 or more inputs as required. Further disclosed is a universal logic array with variable circuit topology. A metallization layer and/or a via interconnection between cells in the array elements produce a circuit topology that implements a Boolean function and/or chaotic function and/or a logic function. The novel circuit provides a circuit topology for secure applications with no obvious physical correspondence between control signal values and input to output mapping. Further disclosed is a network which has a power signature independent of input signal state and output transition. This provides a very useful circuit to protect data from decryption from power signature analysis in secure applications.

Abstract: An orthogonal wavelet division multiplexing (OWDM) communication system including a synthesis section and a channel interface. The synthesis section includes a filter pair bank with multiple inputs and an output that provides an OWDM signal. Each input receives a corresponding symbol of a supersymbol, where the symbols are from a selected modulation scheme. The synthesis section generates the OWDM signal as a combination of weighted OWDM pulses, where each weighted OWDM pulse represents of a symbol of the supersymbol. An OWDM Spread Spectrum (OWSS) communication system that uses broad-time and broadband pulses generated from a family of OWDM pulses together with a set of orthogonal PN code vectors. The OWSS pulses are mutually orthogonal and allow multi-user operation. Each user is assigned an OWSS pulse corresponding to a particular PN code. OWSS enables high rate operation for wireless channels with the use of an equalizer with FE and DFE sections.

Abstract: Spurious energy suppression for a data communication system is achieved without using a large order noise suppression filter, by means of a post-mixer tracking filter that contains a current-controlled MOSFET-implemented resistance for a transconductance-capacitance filter and an associated transconductance tuning stage. The MOSFET-implemented resistance is controlled by the same control current that establishes the output frequency. As a result, the cut-off frequency of the tracking filter is linearly proportional to the carrier and independent of absolute processing parameters and temperature.

Abstract: A radio frequency transceiver includes a radio frequency processor having a modulator/demodulator phase locked loop circuit for generating a second intermediate frequency signal. A heterodyne frequency translation loop circuit receives the second intermediate frequency signal and outputs a first intermediate frequency signal. A transmit mixer receives the first intermediate frequency signal and outputs a transmit radio frequency signal fo. A synthesizer circuit is operatively connected to the transmit mixer and the heterodyne frequency translation loop circuit for generating an oscillation signal to the transmit mixer and the heterodyne frequency translation loop circuit. The oscillation signal is divided down by factor N before passing into the heterodyne frequency translation loop circuit.

Abstract: A transconductor block including a Czarnul tuning network, transconductance resistors, an input voltage follower amplifier, a common mode circuit, PMOS transistors coupled in cascode configuration, an input current source, and high gain amplifiers that drive NMOS transistors at the output. The input voltage follower amplifier receives a differential input signal including a common mode voltage and applies the differential input signal to the Czarnul tuning network. The Czarnul tuning network includes series resistors and is coupled in parallel with the transconductance resistors. The common mode circuit receives the differential input signal and a reference common mode voltage and provides a bias voltage and a common mode feedback voltage. The common mode circuit asserts the common mode feedback voltage to the output PMOS transistors to establish a DC output current and to minimize drift of the common mode voltage of the transconductance block.
