Abstract: This invention is devices, and methods for diverting emboli away from the carotid arteries in the aorta. The devices are aortic diverters (10) that generally comprise a hollow tube (20) with a substantially cylindrical or conical wall (25), which is impermeable to emboli. The hollow tube has a proximal end (30), terminating in a substantially circular edge adapted to fill the lumen of the aorta, and a distal end (40). The proximal and distal ends are substantially open allowing blood to enter the proximal end, flow through the hollow tube, and exit the distal end. The hollow tube also has an anchoring mechanism (50) for securing the hollow tube to the lumen of the aorta. Additionally, snowshoe aortic diverters which are planar rather than cylindrical are also disclosed.

Patent CA-2655817-A1 (CA)
Inventor: WAAGAARD OLE HENRIK
IPC: G01D5/36
Filed: 2006-02-09
Abstract: Unwanted signal components in time-division multiplexed (TDM) systems may lead to crosstalk and noise if these pulses overlap with signal pulses from an interrogated sensor. The crosstalk and noise are dominated by interference between the signal pulses from the interrogated sensor and the unwanted signal components and can be greatly reduced by suppressing this interference signal. The unwanted signal components may include overlapping pulses originating from different sets of interrogation pulses (repetition periods). Modulating the phase or frequency between the repetition periods so that the unwanted interference signal does not appear at frequencies from which the phase of the interrogated sensor is demodulated suppresses this interference. Other unwanted signal components include leakage light during dark periods of the duty cycle of an interrogation signal. Modulating the phase difference between the interrogation signal and the leakage light suppresses the interference between the leakage light and the interrogation signal.

Patent CA-2679576-A1 (CA)
Inventor: APARIN VLADIMIR
IPC: H04B1/52
Filed: 2008-03-21
Abstract: This disclosure describes techniques for reducing adverse effects of TX signal leakage in a full-duplex, wireless communication system. In particular, the disclosure describes techniques for reducing adverse effects of second order distortion of TX signal leakage. To reduce or eliminate second order distortion of transmit signal leakage, a wireless device squares a combined signal that carries both a desired RX signal and a TX leakage signal. For example, the device may include a device that exhibits a strong, second order nonlinearity to, in effect, square the combined signal. The device subtracts the squared signal from the output of the mixer in the receive path, cancelling out at least some of the second-order distortion caused by the mixer. In this manner, the device can reduce the adverse effects of second order distortion of TX signal leakage, and thereby enhance or maintain receiver sensitivity.
