Publication number: 20250239876Abstract: A method of operation is provided during which a pre-charge switch is closed to electrically couple a power supply to a motor controller through a pre-charge supply circuit, where a main switch is open. An electrical parameter of electricity directed through the pre-charge supply circuit is measured when the pre-charge switch is closed and the main switch is open. The main switch is closed to electrically couple the power supply to the motor controller through the main supply circuit when the electrical parameter is equal to or passes a threshold.Type: ApplicationFiled: January 19, 2024Publication date: July 24, 2025Inventors: Raphael Gariepy, Simon Lam, Fraz Ahmad Kharal, Remi Robache, Antwan Shenouda

Publication number: 20240308350Abstract: An assembly for an aircraft includes an aircraft electrical distribution bus, a battery, and a control system. The battery includes a plurality of battery strings. Each battery string includes a string contactor. The control system is in signal communication with the string contactor of each battery string. The control system is configured to control a position of the string contactor of each battery string in a closed string position or an open string position. The control system is configured to: detect a fault in a faulted first battery string of the plurality of battery strings and position the string contactor of the faulted first battery string in the open string position, in response to the detected fault in the faulted first battery string and maintain the string contactor of at least one unfaulted second battery string of the plurality of battery strings in the closed string position.Type: ApplicationFiled: March 18, 2023Publication date: September 19, 2024Inventors: Raphael Gariepy, Simon Lam, Remi Robache, Antwan Shenouda, Richard Freer, Ninad Joshi

Publication number: 20060233768Abstract: An elective healthcare insurance model using an individual's own peripheral blood stem cells for the individual's future healthcare uses. An individual can elect to have his or her own stem cells collected, processed and preserved, while he or she is in healthy or “pre-disease” state, for future distribution for his or her healthcare needs. The process includes methods of collection, processing, preservation and distribution of adult (including pediatric) peripheral blood stem cells during non-diseased state. The stem cells collected will contain adequate dosage amounts, for one or more transplantations immediately when needed by the individual for future healthcare treatments. The collected adult or non-neonate child peripheral blood stem cells can be aliquoted into defined dosage fractions before cryopreservation so that cells can be withdrawn from storage without the necessity of thawing all of the collected cells.Type: ApplicationFiled: March 30, 2006Publication date: October 19, 2006Applicant: NEOSTEM, Inc.Inventors: Thomas Hirose, Simon Lam, Rubio Punzalan, Denis Rodgerson

Publication number: 20050123098Abstract: A method and apparatus to determine an optimum collimator angle of a multi-leaf collimator having an opening and multiple leaf pairs for closing portions of the opening to form a radiation beam arrangement having multiple radiation beam segments. The method and apparatus include application of a cost function to determine a collimator angle which provides for delivery efficiency and target conformity. The user can preferentially either selectively enhance delivery efficiency of the radiation beam arrangement, reducing a number of radiation beam segments and reducing a number of radiation beam monitor units required for delivery of the desired prescription, or selectively enhance conformity of the radiation beam arrangement to a target shape. The optimum collimator angle is then used for delivery of an optimized radiation beam arrangement to a patient by a radiation delivery device.Type: ApplicationFiled: August 11, 2004Publication date: June 9, 2005Inventors: Duan Wang, Robert Hill, Simon Lam

Publication number: 20050052181Abstract: The invention provides for measurement of an actual magnitude of an applied magnetic field, rather than providing a value of magnetic field which is relative to an unknown quiescent value. In particular, by providing a SQUID (100) having an effective area which varies in response to applied flux, an absolute value of magnetic field can be determined due to the change in effective area of the SQUID (100).Type: ApplicationFiled: May 31, 2002Publication date: March 10, 2005Inventors: Simon Lam, David Tilbrook

Patent number: 5822312Abstract: A repeater for a multibeam communications satellite combines the features of coaxial channel interbeam switching and subchannelization of some of the channels. In one embodiment described, the input radio-frequency signals from the input beams are fed through the input multiplexers to form channels. Some, but not all, channels are subsequently subchannelized for interbeam switching. In another embodiment of the invention, a portion of the incoming radio frequency signals bypasses the input demultiplexer and is filtered for noise-limiting reasons, converted down to an intermediate frequency and then subchannelized using SAW filters. The specification also teaches that digital techniques can be used to obtain the same results.Type: GrantFiled: April 17, 1996Date of Patent: October 13, 1998Assignee: COM DEV LimitedInventors: Robert Peach, Nigel Miller, Bharat Tailor, Kamal Ali, Gary Beauchamp, Simon Lam, Ken Lazaris-Brunner
