Patent CA-2647697-A1 (CA)
Inventor: RAMSEY MICHAEL P
IPC: H04B1/16
Filed: 2008-12-22
Abstract: A method of providing audio transmissions from an electronic device having internal audio multiplexing is disclosed. The method comprises combining a plurality of received audio input signals for output as a first mode of operation for the electronic device, where the electronic device is configured to output the plurality of audio input signals on at least one audio channel. When a priority audio signal is detected from one of the received audio input signals in the first mode of operation, the method interrupts playback of the remaining audio input signals with the priority audio signal as a second mode of operation for the electronic device and transfers, within the electronic device, the priority audio signal to the at least one audio channel once the priority audio signal is detected.

Title: Photon counting and integrating pixel readout architecture with dynamic switching operation
Inventor: KARIM KARIM S
IPC: H04N5/335
Filed: 2009-01-16
Abstract: A new pixel readout architecture is presented for direct conversion radiation detectors (for example, amorphous selenium). Photon-counting operation provides excellent sensitivity to low radiation doses but saturates the system at medium to high doses due to the poor charge transport properties of a-Se. Thus, we present a photon counting readout circuit design that is also capable of dynamically operating in integrating mode to enable the detection of high-dose radiation. This extends the resolvable dynamic range of the imaging system from very low gamma-ray count rates to very high flux x-ray radiations. The readout architecture thus is promising for applications such as mammography tomosynthesis and fluoroscopy, and its benefits can be extended to other radiation detectors as well. We also show spectroscopy results with a-Se and show the circuit's simulated behaviour of dynamically switching between counting mode and integrating mode to show the wide resolvable operating range.

Title: Acoustic method and apparatus for detection and characterization of a medium
Inventor: VILMING STALE
IPC: G01N29/02
Filed: 2007-04-25
Abstract: An acoustic method and apparatus for detection or characterization of a medium comprised in a structure. Typically, the structure is a container, such as e.g. a pipe line for transportation of oil, gas or hydrocarbon condensate. A pulse of broad banded acoustic energy is emitted towards said structure by a first transducer means. A return signal is generating by a second transducer means from acoustic energy returned from said structure in response to said emitting. A return signal spectrum representing acoustic spectral components of said acoustic energy returned from said structure is derived from said return signal, and said medium is detected or characterized by applying a return signal processing medium detection or charaterization algorithm to said return signal spectrum.
