Abstract: A rotary shaft position sensor includes a stator (22) and a rotor (24) and produces a linear output signal in accordance with the rotational position of a shaft (68) coupled to the rotor. The rotor rotates about an axis of rotation. The stator includes stationary pole pieces (42, 44) having stationary pole faces situated perpendicular to the axis of rotation and spaced a predetermined distance apart to define an air gap therebetween. A Hall effect device (50) is situated in the air gap. The Hall device (52) produces an output signal corresponding to the level of magnetic flux in the air gap. One or more magnets (58) are attached to the rotating pole piece (60). The magnetic poles of the magnets are situated parallel with and spaced a predetermined distance from the stationary pole faces. Lines of magnetic flux originating from the magnets are situated in a direction perpendicular to the stationary pole face (54, 56). The rotating pole piece rotates in close proximity to the stationary pole piece (42, 44). As the rotor rotates about the axis of rotation, a portion of the magnet is aligned with the stationary pole faces (54, 56). Magnetic flux corresponding to the aligned portion of the magnet and the stator pole faces appears in the air gap. A temperature compensation circuit for use with the rotary shaft position sensor includes first and second temperature compensation circuits for counteracting sensitivity temperature drift and zero gauss offset temperature drift characteristics of the Hall effect device (50).

Abstract: A method of optically measuring volatile impurities in contaminated medium using a combination of a distillation process with head space analysis is described. The method uses a hydrophobic extracting membrane at the surface of an internal reflection element (an optical fiber or an attenuated total reflection crystal). The hydrophobic analytes are extracted into the extracting membrane, from the contaminated medium. By heating the contaminated medium to form a vapor and cooling the sensor element surrounded by the extracting membrane, the limit of detection is significantly reduced by between two and three orders of magnitude from the prior art. The distillation aspect of the method also protects the extracting membrane surrounding the sensor from mechanical damage by the solid impurities in the contaminated medium. A simultaneous continuous analysis of several impurities of the contaminated medium is possible by employing several optical fibers arranged in parallel on the same cooling device, each of which is designed for a specific contaminate by means of optical filters, wavelengths disperging elements (gratings or prisms) or wavelength selective IR sources or detectors.

Abstract: A tubular anchor may have a polygonal cross-sectional configuration with flat outer side surfaces areas connected by a plurality of outer corner portions. A passage through the anchor may be formed by flat inner side surfaces interconnected by inner corner portions. A suture is inserted through the passage. A concentrated force may be applied against a limited area on a trailing end of the anchor to rotate the anchor to move an outer corner portion of the anchor into engagement with body tissue. The suture may engage an inner corner portion of the anchor. The suture may be inserted through a plurality of anchors and the anchors moved through a tubular member into the body tissue under the influence of force transmitted from a trailing anchor to a leading anchor. When the leading anchor is moved into the body tissue, it is rotated under the influence of force applied against a trailing end of the leading anchor. If desired, two anchors may be interconnected. A groove may advantageously be provided along the leading end and side of an anchor to receive the suture.

Abstract: A method and system for permitting effective data compression in a system which employs short message lengths. A history buffer in association with each sender and receiver within the system has a length substantially longer than the average length of a data message. Every message to be transmitted by the sender over an extended period of time is then stored within the associated history buffer at the sender and at the receiver such that the history buffer will eventually be filled. This is accomplished by maintaining the history buffer at a current state despite a temporary cessation of data transmission between the sender and receiver. Each time a new message is to be transmitted by the sender the content of the message as compared to the content of the history buffer to determine if a match exists between some portion of the message and some portion of the content of the history buffer. If a match occurs, a pointer to the matching portion within the history buffer is transmitted in place of the portion of the message and the message portion is then reconstructed at the receiver, greatly reducing the data transmission requirements. The history buffer is preferably provided utilizing a content addressable memory in order to enhance the efficiency of match determination and speed.

Abstract: A mechanism which manages variable length instructions in cache is comprised of three cooperating elements designed to optimize self modifying code and anticipate next instructions for branch operand management. A content addressable memory (CAM) stores addresses of lines which have been accessed for instruction fetching. In a system having modifiable instruction stream (i.e., store to instruction stream), when the CAM matches, the system must retire certain instructions, flush instructions and then fetch the modified instruction stream. Boundary identification logic examines a field in each cache byte to determine the nature of the byte. This field is initially cleared at the time the cache line is loaded and filled with the line is fetched. An anticipation buffer designed to minimize the circuitry necessary for fetches across cache lines is loaded with sequentially anticipated prefetched instructions from the cache. These anticipated instructions can then be concatenated by a fetch aligner.
