Abstract: A simple optical position encoder of detecting the position of a light spot generated by any light source of either light generating or light reflecting type, directly in a binary or other encoded format at very high speed, comprises a diffractive optical element including an array of diffractive cells each being formed by a unique arrangement of diffractive sub-cells and being disposed at a predetermined position with respect to a predetermined reference point on the diffractive optical element. Each cell is capable of generating a unique optical diffraction pattern when illuminated. When an image of the light spot is formed on the diffractive element, at least one cell is positioned to receive the light spot input image, generating its unique optical diffraction pattern accordingly at an output image plane, where one or more optical detectors are disposed. The detectors are responsive to the unique optical diffraction pattern to generate one or more encoded signals indicative of the position of the light spot image with respect to said reference point. Described applications of the basic embodiment of the position encoder includes absolute three-dimensional position measurement of a light spot formed on a object, position encoding of a light peak generated by an optical processor or correlator and absolute/relative position detection of a light spot generated by or reflected onto an object in a two-dimensional coordinates system.

Title: Method and circuit for storing and providing historical physiological data
Inventor: SWEDLOW DAVID B
IPC: A61B5/00
Filed: 2000-03-07
Granted: 2010-09-07
Abstract: A mechanism for storing and providing historical physiological data, such as blood oxygen saturation data, for a patient. In particular, the historical physiological data is stored in a storage medium that "travels" with the patient and is accessible wherever the patient is moved. This is achieved by storing the physiological data within a sensor assembly. At the destination site, a monitor or a device capable of interfacing with the sensor electronics can retrieve and display the data. The historical physiological data allows a clinician or medical personnel at the destination site to assess the condition of the patient for the entire time that the patient has been monitored. Various types of physiological data can be stored including, but not limited to, blood oxygen saturation, heart rate, and temperature data. Compression of the data can be performed to enhance the storage capability.

Abstract: A relatively low-cost calendering belt having excellent heat resistance and durability comprises a central portion 30, and left and right side portions 20 located at the sides of the central portion. The right and left portions 20 comprise high molecular weight elastic material having greater heat resistance than that of the central portion 30. The central portion 30 is composed of high-molecular elastic material, the durability of which is higher than that of the right and left portions 20. The heat of the calender roll CR is intercepted by a paper W, and consequently is not transmitted to the central portion 30 of the calender belt. The right and left portions 20 of the calender belt, which are not protected by paper W do not deteriorate readily as a result of the heat of the calender roll CR because of their heat resisting property.
