Patent CA-2405825-C (CA)
Title: Pulse oximeter sensor with piece-wise function
Inventor: MANNHEIMER PAUL D
IPC: A61B5/145
Filed: 2001-04-16
Granted: 2010-11-09
Abstract: A memory in a sensor is used to store multiple coefficients for a physiological parameter. In one embodiment, not only are the sensor's specific calibration coefficients stored in a memory in the sensor for the formula to determine oxygen saturation, but multiple sets of coefficients are stored. The multiple sets apply to different ranges of saturation values to provide a better fit to occur by breaking the R to SpO2 relationship up into different pieces, each described by a different function. The different functions can also be according to different formulas for determining oxygen saturation.

Granted: 2004-02-24
Abstract: An apparatus includes an air compressor containing a piston in a cylinder, a flywheel having an axis of rotation, and an elongated linkage structure interconnecting the flywheel with the piston. A support member projects from the flywheel. A bearing supports the linkage structure on the support member. The linkage structure has an inner edge surface defining an opening in which the bearing is received in an installed position. The inner edge surface of the linkage structure extends continuously in a loop around the opening, and has an annular portion which is interrupted across a circumferentially extending gap. The linkage structure further has a portion configured as a living hinge which enables the gap to enlarge upon flexure of the hinge. This enables the bearing to be installed in the opening with an interference fit between a cylindrical outer surface of the bearing and the annular inner surface of the linkage structure.

Title: Method of purification of a redox mediator before electrolytic regeneration thereof
Inventor: MAHDAVI BEZHAD
IPC: C25B3/23
Filed: 2002-01-24
Granted: 2009-03-24
Abstract: A method for purifying a Redox mediator used in a chemical process of oxidation of organic compounds. The desired purification is obtained by recovering the mediator in the form of a solution and heating this solution to evaporate the volatile impurities contained in it and to oxidize the non volatile impurities into compounds which precipitate and are extracted by filtration. The purification takes place before the mediator is regenerated in the electrolysis cell. This prevents the impurities contained in the mediato r solution to negatively affect the operation of this cell.

Title: Band refeeding method in banding packing machine and banding packing machine having refeeding mechanism
Inventor: TSURUMAKI SABURO
IPC: B65B13/18
Filed: 2003-09-30
Granted: 2007-05-22
Abstract: It is an object to provide a band refeeding method in a banding packing machine which can prevent the tip portion of a band from being excessively pulled back even if the band is not supplied correctly but is automatically pulled back, and can stay the band in a predetermined position and can successively supply the band to the band guide arch side. A length of a band to be pulled back to an original position by band pull back means (84) is previously detected based on the number of rotations of a touch roller (88) constituting band supply means (82). In addition, the number of rotations of the touch roller (88) before reaching a predetected set value is detected when the tip portion of the band is pulled back. Then, a rotating speed of a roller (94) of the band pull back means (84) is reduced when the number of rotations is detected. Therefore, the roller (94) of the band pull back means (84) is subsequently rotated at the low speed, thereby pulling back the tip of the band to a predetermined position.
