Abstract: The invention relates to devices and methods of maintaining the current starved delay at a constant value across variations in voltage and temperature to increase the speed of operation of the sequential logic in the radiation hardened ASIC design.

Abstract: The invention relates to an improved K-Delta-1-Sigma Modulators (KG1Ss) that achieve multi GHz sampling rates with 90 nm and 45 nm CMOS processes, and that provide the capability to balance performance with power in many applications. The improved KD1Ss activate all paths when high performance is needed (e.g. high bandwidth), and reduce the effective bandwidth by shutting down multiple paths when low performance is required. The improved KD1Ss can adjust the baseband filtering for lower bandwidth, and can provide large savings in power consumption while maintaining the communication link, which is a great advantage in space communications. The improved KD1Ss herein provides a receiver that adjusts to accommodate a higher rate when a packet is received at a low bandwidth, and at a initial lower rate, power is saved by turning off paths in the KD1S Analog to Digital Converter, and where when a higher rate is required, multiple paths are enabled in the KD1S to accommodate the higher band widths.

Abstract: The invention relates to devices and methods which implement a reconfigurable network-on-a-chip (NoC) multiple-input-multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) application specific integrated circuit (ASIC) architecture which fully implements a 4×4 MIMO OFDM receiver and transmitter, which has a radiation hardened phase-locked loop (PLL) that provides a 1 GHz or 500 MHz clock to a NoC switch fabric, and at least two NoC Clusters on said NoC switch fabric, an Up/Down conversion cluster and a main MIMO OFDM and Single Carrier system cluster.

Abstract: The present invention relates to portable wireless communication systems, in particular for sending and receiving data including position information using radio frequencies. The invention comprises: (i) a hand held digital computer; (ii) a position-locating device providing position information to the digital computer; (iii) a VHF and/or UHF radio frequency transmitter; and (iv) a radio modem having an input for digital data from the hand held digital computer, a modulator for converting digital data from the computer into a modulated analogue RF signal, and an output connected to the transmitter for transmission of said modulated signal.

Abstract: To allow meter data users to have access to needed information and at the same time address the rapidly shifting requirements of the deregulated marketplace, a new business model employs a common metering device that measures raw data and a system composed of independent services or applications that collect and process raw metered data and then make that data available to interested parties. This new model removes the dependence upon an automatic meter reading (AMR) system provider, as the sole provider, by creating a system to enable a competitive environment where services (applications, information, networking, etc.) rather than systems are selected and paid for on a leased or pay-per-use basis.

Abstract: A method and device for analog simultaneous voice and data transmission over an analog channel encodes at a voice signal sampling rate a sampled voice signal including spectral and pitch information. During encoding, the spectral and pitch information is extracted from the sampled voice signal to produce a residual signal, and the residual signal is converted into a sequence of residual vectors at a Baud rate. Then, a bitstream including non voice data and the extracted spectral and pitch information is produced. A modem unit, operating at Baud rate and producing an output carrier wave supplied to the analog channel, produces a sequence of symbol vectors in response to the sequence of residual vectors and the bitstream, and modulates the output carrier wave in response to the sequence of symbol vectors.
