Title: Method and apparatus for improving the resolution of pulse position modulated communications between an implantable medical device and an external medical device
Inventor: FERNALD KENNETH WILSON
IPC: A61N1/372
Filed: 1995-10-31
Abstract: A method and apparatus is disclosed for use in an implantable device that communicates with an external device through pulse position modulation. A  timing generator is provided as part of said implantable device that determines the phase uncertainty between an external signal and an internal clock signal. The phase uncertainty then is added to the preset delay period to more precisely control the position of the response. The phase uncertainty is measured by a dual slope circuit that varies a state variable (which can be a digital timer, a capacitor voltage, or the like) at a fixed rate with either a positive or negative slope. When the external signal is detected, the state variable is reset and then decreased at a fixed rate until the next positive edge of the clock signal. The state variable then is increased at the same rate until the subsequent positive clock edge. The resulting variable value is proportional to the phase uncertainty. When the delay timer reaches zero, the state variable is again decreased at the same fixed rate until the initial value is reached, at which the output response is generated.

Patent CA-2215888-A1 (CA)
Title: Wellbore profiling system
Inventor: HAY ROSS
IPC: E21B47/06
Filed: 1997-09-17
Abstract: A method is presented for accurately surveying and determining the profile of the path of a subterranean wellbore containing a constant density fluid extending contiguously throughout. A first pressure sensor, associated with a downhole tool, is traversed station-by-station along the wellbore for measuring the pressure of the fluid within the wellbore at each station. A second pressure sensor is located within the wellbore fluid at a known elevation. The elevation of the first pressure sensor, at a station, is determined by adding the calculated differential height to the known absolute elevation of the second sensor. As each elevation is referenced to the second sensor, no cumulative errors are incurred. If the density of the fluid is unknown, a third pressure sensor within the wellbore fluid can be provided at a known elevation different from that of the second sensor. The areal position of each station is determined by conventional means associated with the downhole tool. The elevation for each of a plurality of stations is combined with the areal position determined at each station to determine the path of the wellbore.

Patent CA-2219228-A1 (CA)
Inventor: TODD STEPHEN ROSS
IPC: H04B7/08
Filed: 1997-10-24
Abstract: A diversity selection process which tests to determine whether poor reception is caused by co-channel interference or multipath fading is disclosed. The impairment is determined by first testing the quality over several frames. Unless the quality is poor over these several frames, the system tests for multipath fading by selecting the antenna with the greater signal strength, provided no hold condition exists. However, if poor quality has been present over the several frame period, the system selects the other antenna if its RSSI is greater. However, the system also tests the RSSI received on the current antenna and determines the impairment was co-channel interference if the signal of quality was sufficiently high. In which case a hold condition is set for a number of frames to prevent excessive switching.
