20120281083 | Thermal Imager with Hermetically Sealed and Pressurized Housing - The present invention relates to an imaging device with a thermal imaging surveillance capability for safety, security and situational awareness. Closed circuit television systems (CCTV) are usually supported on drive and actuating mechanisms so that their active imaging portions are housed in a protective environment in a transparent dome. Existing thermal imaging devices are used in fixed configurations or on platforms and are bulky and expensive. In addition they are unsuitable for harsh marine environments. The invention is an imaging device and comprises: a thermal imager, which in use is housed within a sealed housing. A pan and tilt mechanism is supported in the housing for displacing the thermal imager. A dome, formed from an infra-red (IR) transmitting material, covers and seals the housing (which is ideally filled with an inert gas) thereby resulting in an arrangement that is resistant to exposure to water and salt and so provides an imager suitable for marine environments, as well resulting in an overall reduction in size of the imager compared with exposed pan and tilt mechanisms. | 11-08-2012 |

20110302061 | System and Method of Providing Spending Information by Foreign Visitors Using Transaction Records of Financial Presentation Devices - A system for providing spending information in a locality by foreign visitors using transaction records of financial presentation devices such as credit and debit cards that are presentable to merchants is disclosed. A storage device stores transaction data generated from card transactions. A transaction analysis module executable by a processor generates a filtered set of transaction records that exclude, from the stored data, a set of transactions which are indicative of having been made by long term residents of the locality, rather than by residents of foreign regions, in order to improve the accuracy of true foreign visitors to the locality. For example, the system filters out from the database all transactions of accounts that have made a bill-pay transaction. As another example, the system filters out non face-to-face transactions and all transactions with mail order and catalog merchants, and schools. Based on the filtered data, the transaction analysis module generates a spending report containing an aggregated amount of the transactions for each foreign region of the holders who have performed the transactions in the locality. | 12-08-2011 |

20100189208 | System and method for clock jitter compensation in direct RF receiver architectures - Systems and methods that provide clock jitter compensation architectures that improve the performance of direct radio frequency (RF) receivers by injecting a calibration tone into the received radio frequency (RF) signals in order to help identify and then compensate for the clock jitter noise. After injecting the tone, the jitter noise going through the direct RF bandpass sampling receiver is estimated using a narrow bandwidth filter, and the received signals are further processed and demodulated depending on the Nyquist zone of the received signal. The relative modulation factor for the modulation is computed and then applied to the Nyquist zone to de jitter that particular Nyquist zone. | 07-29-2010 |
20100202566 | System and method for improved spur reduction in direct RF receiver architectures - Improved spur reduction architectures that improve linearity in direct radio frequency (RF) receiver architectures. Non-uniform sampling in the form of sampling clock phase (or frequency) modulation is used to induce phase (or frequency) modulation on signals that are being received from a given Nyquist zone. At the output of the ADC (analog-to-digital converter), the signals are de-modulated to remove the induced modulation based on the Nyquist zone that is being received. The de-modulation process results in non-desired spurious artifacts (interfering leakage signals and ADC spurs) being spread in the frequency domain. Strong spurious artifacts may be removed after measuring the induced modulation and de-modulating. For the case of weak spurious artifacts, the de-modulation for the desired Nyquist zone spread these signals in the frequency domain. Induced modulation on signals may also provide a dithering effect on the ADC. | 08-12-2010 |
20100277283 | Systems and methods for RFID tag operation - A RFID tag system may be configured as a tag having a first band (e.g., multiple channel-based NBFM frequency band) transceiver to allow field programmability of tag behavior and onboard tag data. The RFID tag system may be configured to collect data from one or more local sensors through the first band link and store data points of interest in tag onboard storage. The RFID tag system may be configured to work in conjunction with a remote interrogating unit, and a handheld device or other local interrogating unit may be additionally or alternatively provided to communicate with such aRFID tag. Data that is stored on the RFID tag may be retrieved or changed, and/or the operation of the tag may be modified. | 11-04-2010 |
20100278214 | Pulse-level interleaving for UWB systems - Systems and methods are disclosed that provide pulse-level interleaving for multi-pulse-per-bit ultra wideband (UWB) transmit and receive processing techniques to provide significantly improved multi-access for UWB systems and, more particularly, for long range UWB systems. A bit stream is processed such that each bit in a bit stream is represented by a plurality of bits in a bit frame and then transmitted using a plurality of UWB pulses for each bit frame. Where on-off-keying (OOK) modulation is used, each logic “1” is sent out as a plurality of pulses, and each logic “0” is sent out as a plurality of non-pulses. Pulse-level interleaving (PLI) of the pulses across multiple bit frames prior to transmission is provided to allow for improved multi-access (MA) by a plurality of UWB transmitters operating at the same time. Rather than attempt to detect each pulse as it arrives at the receiver, the receiver instead first de-interleaves the pulses and then aggregates the energy from the multiple pulses within each bit frame. The aggregated pulse energy is then processed by a pulse detector to detect a pulse. Where OOK modulation is used, this pulse detection detects the existence of a pulse or the lack of a pulse within the bit frame. | 11-04-2010 |
20120170618 | Ultra wideband time-delayed correlator - The present invention is for a method and apparatus to improve an Ultra Wideband (UWB) digital receiver's performance sensitivity. A transmitted signal stream has each data bit having multiple identical modulated pulses separated by a constant time interval. The received signal stream is duplicated to create a second signal stream of identical modulated pulses to the original signal stream. The duplicated signal stream is delayed by the constant time interval between identical modulated pulses and the two signal streams correlated to form one signal stream which is detected to improve the sensitivity of the receiver. | 07-05-2012 |
20120201274 | Ultra-wideband dual band magnitude summer apparatus and method - This invention relates to capturing and processing the full bandwidth of an Ultra-Wideband (UWB) signal.

20090171632 | AUTOMATIC BNE SEED CALCULATOR - An automatic background noise estimator (BNE) seed calculator for determining a starting point for a BNE circuit which tracks the noise floor received by a receiver. The BNE seed calculator may sample a plurality of data points from the receiver and calculate the magnitude of each point. The seed calculator may then determine the peak magnitude value, a plurality of mean values, and the variance of the sampled points. A plurality of lookup tables are used to compare the peak, mean, and variance values with simulated peak, mean, and variance values to estimate the noise floor level of the actual signal and use that to determine the optimum BNE seed value. Simulation software such as MATLAB is used to develop the lookup tables by simulating peak, mean, and variance values based on a plurality of signal-to-noise ratios (SNR). | 07-02-2009 |
