Patent CA-2222617-C (CA)
Inventor: SHERMAN MARSHALL L
IPC: A61B17/22
Filed: 1996-05-01
Granted: 2002-07-16
Abstract: This invention is a power control system and method that controls a power generator (50) to vary the duty cycle of a power output provided to a delive ry instrument (10) for delivering that power to a site in a patient for ablatio n. The peak power can be raised and the duty cycle lowered to result in deeper lesions. A power output having a higher peak power for producing deeper lesions can be obtained by using a lower duty cycle having a longer "off" period in order to deliver more power to the ablation site without overheati ng the delivery instrument (10). The temperature of the delivery instrument is monitored, and the duty cycle is lowered when the temperature exceeds a predetermined maximum limit. After the instrument has cooled sufficiently, t he duty cycle is then increased to its previous level.

Abstract: A method and system of forming and processing communication links in a satellitecommunications system. The satellite communications system includes a plurality of groups of transmitters, a satellite and a plurality of destination receivers. Each transmitter is associated with only one transmitter group and transmits a communications signal. Each respective communications signal is a CDMA signal having a predetermined code that is associated with a transmitter. Each respective predetermined code is selected from a code set assigned to the group of transmitters with which the transmitter is grouped. Each code set is different from code sets associated with the transmitters of other selected transmitter groups so that the code sets are arranged in a code set pattern that is repeated for selected groups of transmitters. The satellite receives the communications signals and groups together each received communications signal having a same predetermined code set. The code sets of selected uplink communications signals in a group of received communications signals are fully or partially despread, filtered, and respread so that the group of communications signals contains communications signals from only one code set. Each group of communications signals is then transmitted to a different destination receiver, or groups on different code sets to the same destination receiver.

Abstract: Adaptive antennas are used to counter dispersion due to multipath propagation and interference from other stations using the same frequency. Each of the antennas in the array has a respective tapped delay line in which the tap output signals are weighted and summed. In a known theoretical proposal, the weights W are determined as follows:   w = R xx -1 r xd where R xx is the autocorrelation matrix of the input to the system and r xd is the crosscorrelation vector of the input signal and the known sequence. In practice estimates of R xx and r xd may be obtained by averaging the instantaneous matrices and vectors over the training sequence.      A method to provide an improved estimate of R xx is disclosed in which the estimate of R xx is refined by calculating a new estimate R xx(new) = (R xx + .beta..I x trace(R xx)) where .beta. is a scalar value and I is the identity matrix, and wherein successive iterations are evaluated by:     comparing the real part of the summed tap output signals with a set level; ascribing a symbol value of logical zero to those summed tap output signals which fall to one side of the set level and ascribing a symbol value of logical one to those summed tap output signals which fall to the other side of the set level; calculating the mean of the levels of those signals ascribed the value logical zero and the mean of the levels of those signals ascribed the value logical one; calculating the distance between the level of each signal ascribed the value logical zero and the respective mean, and the level of each signal ascribed the value logical one and the respective mean; calculating the sum of the distances from the means; calculating the distances of the levels of all signals from the set level; calculating the sum of the distances of the levels of all signals from the set level; calculating the ratio of the sum of the distances from the means to the sum of the distances of the levels of all symbols from the set level.

Abstract: A digital switching power amplifier with Multivariable Enhanced Cascade Controlled (MECC) includes a modulator, a switching power stage and a low pass filter. In the first preferred embodiment an enhanced cascade control structure local to the switching power stage is added, characterised by having a single local feedback path A (7) with a lowpass characteristic and local forward blocks B1 or B (3, 4). The leads to a much improved system with a very low sensitivity to errors in the switching power stage. In the second preferred embodiment of the invention the control structure is extended with a global structure composed of a single feed-back path C (8) and forward paths blocks D1 or D (1, 2). This provides further improvements and a very low sensitivity to load variations and filter errors. Both MECC embodiments are characterised by being simple in implementation, stable and extendible by adding/removing simple local (3) or global (1) forward path blocks. A third embodiment of the invention is a controlled self-oscillating pulse modulator, characterised by first a non-hysteresis comparator as modulator and second by a higher order oscillating loop realised in both forward path B1 and feedback path A to determine stable self-oscillating conditions. An implemented 250W  example MECC digital power amplifier has proven superior performance in terms of audio performance (0.005 % distortion, 115 dB dynamic range) and efficiency (92 %).
