Title: Space-based network architectures for satellite radiotelephone systems
Inventor: KARABINIS PETER D
IPC: H04B7/216
Filed: 2002-08-23
Granted: 2010-06-08
Abstract: A space-based network for a satellite radiotelephone system includes at least one receive-only satellite (1320a, 1340a) and at least one transmit satellite.  The transmit satellite can be a transmit-only satellite (1310) or a transmit and receive satellite. The receive-only satellite(s) are configured to receive wireless communications from a radiotelephone at a location over a satellite frequency band. The transmit satellite(s) are configured to transmit wireless communications to the radiotelephone at the location over the satellite frequency band. By providing at least one receive-only satellite and at least one transmit satellite, space-based networks can offer a significant link margin, without the need to undesirably burden the radiotelephones themselves to achieve this link margin.
Patent CA-2466162-C (CA)
Inventor: DOSS JEFFERY S
IPC: H02M3/335
Filed: 2002-10-30
Granted: 2007-07-24
Abstract: A dual input battery assisted power converter (10) which provides a continuous, regulated DC voltage output to a user-connected mobile device, such as, a laptop computer or a cell phone, for example. The power converter (10) comprises a power supply circuit (12) and a separate, detachable power storage circuit comprising a battery pack (14) having a re-chargeable battery (36). The power supply (12) is adapted to deliver a pair of regulated DC  output voltages, of opposite voltage potentials, to a pair of respective output terminals. Preferably these output voltages are derived from two external input voltages: an AC input voltage and a DC input voltage.  Advantageously, if both of the external input voltages are temporarily removed, the battery pack (14) will advantageously serve as a substitute DC  input power source, thereby allowing the power supply (12) to deliver the same regulated DC output voltage to the user-connected mobile device without interruption. Moreover, once either of the external input voltages are again re-established, the battery pack (14) automatically taps the output terminal of the power supply (12) at a node to recharge the battery pack (14).

Title: Composite laminated sheet material for containment sumps
Inventor: FINK RONALD JAMES
IPC: B29C41/08
Filed: 2005-03-09
Granted: 2010-02-02
Abstract: The present invention is a composite laminated sheet material suitable for structures such as containment sumps. The laminated material comprises a fabric-backed thermoplastic layer upon which thermoset plastic is applied to the fabric side. The thermoplastic layer is formed by contacting a layer of fabric onto a lay er of molten thermoplastic such that the liquid thermoplastic permeates a portion of the fabric layer to form a mechanical bond with the fabric layer when the thermoplastic layer cools and hardens. Thermoset plastic, such as fibreglass resin, is sprayed onto the fabric side of the thermoplastic layer to allow the liquid resin to permeate the fabric layer. Once the resin cures and hardens, the fabric layer is mechanically bonded to the cured thermoset plastic layer to effectively bond the thermoplastic layer to the thermoset plastic layer.

Abstract: This invention concerns airborne geophysical surveys and the processing of vector magnetic data from those surveys to remove the aircraft effect.  Coefficients representing the permanent and induced magnetic effects are calculated from data obtained during a calibration flight, with reference to the aircraft coordinate system. Then an airborne geophysical survey flight is conducted, and the permanent and induced magnetic effects are removed from the survey flight data in the aircraft coordinate system. The corrected survey flight data is rotated into the NED coordinate system, and the eddy-current effect is removed from the corrected survey data in the NED coordinate system.

Granted: 2010-12-07
Abstract: The present disclosure presents a predictive signal producing method that effectively levels transmitter output power in a multi-carrier communication system and results in approaching amplifier performance normally associated with constant carrier waveforms. Embodiments of the disclosed solution offers >10 dB reduction in the peak-to-average power required to support the transmission of, for example, orthogonal frequency division modulation ("OFDM") modulation techniques. Embodiments of the novel system and method maximize peak-to-average power ratio ("PAPR") reduction with selective mapping and soft clipping, which may include filtering, combined. This novel approach also minimizes overhead, bit error rate, retransmissions, and increases latency as well as implementing processing cycles with a number of iterations. The disclosed system and method improves the total system DC power efficiency and provides an optimal solution for PAPR reduction in multi-carrier communication systems such as, for example, OFDM.

Abstract: The current invention is a spinal and upper cervical impulse treatment device and controller, which delivers multiple impulses of variable frequency and variable force in a linear direction, as well as rotational forces, for patient treatment. Known medical impulse devices are all hand held devices. In contrast, the spinal and upper cervical impulse treatment device is mounted on a fixed stand and armature, allowing reliable positioning and directional alignment in three dimensions.  Fixed mounting also facilitates ease of use. A safety coupling is incorporated to avoid patient injury due to excessive force on the treatment site in the fixed mounting scenario. Smooth sinusoidal waveforms are a preferred waveform for impulse delivery and sine waves are generated digitally in the apparatus. Data validation is used to ensure correct directional alignment prior to device activation Patient safety and consistency in treatment protocols are considered in the spinal and upper cervical impulse treatment design.
