Patent CA-2353819-A1 (CA)
Title: Methods of driving an array of optical elements
Inventor: CROSSLAND WILLIAM ALDEN
IPC: G09G3/36
Filed: 1999-12-16
Abstract: Relates to writing an array of optical elements which are each switched between two states according to input data sets. In a first method, data is written in two steps in which different selected elements are respectively driven to one binary state and the other binary state. The selected elements of the two sets may be complementary, but are preferably only those which are required to change from their existing state. The latter criterion may be used in an alternative method using a single addressing of the array to turn elements in either direction as required. In a further method, as shown, selected elements only of a blank array are written in a first WRITE step so as to correspond with a set of data, and in a subsequent second ERASE step the selected elements are selectively erased to restore a blank array prior to writing and erasing another set of data. The methods have particular utility for maintaining a dc balance at pixels of a liquid crystal array.

Patent CA-2368613-A1 (CA)
Inventor: DIAB MOHAMED K
IPC: A61B5/1455
Filed: 2000-03-24
Abstract: An intelligent, rule-based processor (300) provides signal quality based limits to the signal strength operating region of a pulse oximeter. These limits are superimposed on the typical gain dependent signal strength limits  (314). If a sensor signal appears physiologically generated, the pulse oximeter is allowed to operate with minimal signal strength, maximizing low perfusion performance. If a sensor signal is potentially due to a signal induced by a dislodged sensor, signal strength requirements are raised. Thus , signal quality limitations enhance probe off detection without significantly  impacting low perfusion performance. One signal quality measure used is puls e rate density (354), which defines the percentage of time physiologically acceptable pulses are occurring. If the detected signal contains a significa nt portion of unacceptable pulses, the minimum required signal strength is rais ed proportionately. Another signal quality measure used in conjunction with pul se rate density is energy ratio (352), computed as the percentage of total ener gy contained in the pulse rate fundamental and associated harmonics.
