Title: Multiplexed memory timing with block reset and secondary memory
Inventor: URBANUS PAUL M
IPC: G09G3/34
Filed: 1995-05-23
Abstract: A spatial light modulator array with adaptable multiplexed memory architecture. The modulator has an array of individually controllable pixels, where a predetermined number of pixels are assigned to a memory cell (16). The memory cell receives data from an input bus (14). On a signal (22), the memory cell transfers its data to a secondary memory (18), and to the activation circuitry (20) of one of its assigned pixels. On a second signal, the pixel responds to the data on the activation circuitry. When the display time of the data is less than the load time for the memory cell, the secondary memory is set with a second signal (24) so as to make the pixel dark and another control signal makes the pixels respond to the memory. In this way, the load time is lengthened and the data rate remains relatively low, even though the number of bits of intensity may not be the same as the number of bits of intensity used to determine the number of pixels assigned to each memory cell.

Abstract: A vacuum head having a confinement zone with a portion of surfaces inside a water pool, under the vacuum head, for cleaning surfaces of the floor and adjacent sides, inside a water pool. A water outlet is mounted within the confinement zone, whereby the presence of water in the confinement zone generates a flow of water driven toward the water outlet. A plurality of water jets within the confinement zone impinge water upon the portion of surfaces, under the vacuum head, for the water from the water jets to hit the portion of sur-faces within the confinement zone, to remove dirt from said portion of surfaces, and said dirt together with said water to be substantially confined within the confinement zone, and be displaced along the flow of water driven toward the water outlet. A method for cleaning surfaces of the floor and adjacent sides comprises creating a negative pressure zone at least partially impermeable to the water inside a water pool to obtain a confinement zone having a flow of water driven toward said water outlet, and inside said negative pressure zone, impinging water upon surfaces for cleaning inside a water pool.

Title: System and method for the algebraic derivation of physiological signals
Inventor: TIEN JONATHAN
IPC: G06F17/00
Filed: 1996-05-15
Abstract: A technique for the algebraic derivation of a pulse oximetry signal uses the mathematical relations of detected light signals. First and second light sources transmit light through the patient's finger or reflects light off the blood vessels in the patient's finger. A light detector detects light from each of the light sources and generates a measured intensity signal. The measured intensity signal includes the true intensity of light transmitted from each of the light sources as well as noise introduced during the measurement process. A data sample from each of the light sources is digitized and subdivided into a plurality of data windows. The mathematical relationship is applied to each of the data windows to determine a ratio value indicative of oxygen saturation in the patient. The ratio values are statistically analyzed to determine the best estimate for the correct ratio value. This ratio value is subsequently processed to determine the oxygen saturation within the patient.
