Title: Acetabular cup positioning insert with release mechanism
Inventor: KASHUBA GLEN A
IPC: A61F2/30
Filed: 1994-01-28
Abstract: An acetabular cup for use as a prosthetic implant has an insert (12) with a body (16) including a central bore (18) for receiving a positioning rod (22) therein. A key element (20) is formed on the bore and is adapted to align the positioning rod. The insert has a locating element (58) formed on an outer surface of the body and also includes spring elements (19) extending radially outwardly from the body. The acetabular cup (14) has a generally hemispherical shell (15) member coupled to the outer surface of the insert. The shell has an outer surface (30) for engaging the acetabulum and an inner surface (32) having a, circumferential groove (36) for receiving the spring elements (19). The spring elements may be deflected radially inwardly out of engagement with the groove for releasing the insert from the shell. The spring elements can be deflected by pushing a sleeve down the rod to make contact with and deflect the spring element. The shell has a plurality of apertures (34)extending from its inner to its outer surface, which apertures are located an asymmetrical pattern about the shell. The shell includes a recess (62) on its open end for receiving the locating element on the insert to align the insert at a predetermined orientation with respect to the apertures in the shell. The engagement of the insert onto the shell and the engagement of the locating element in the recess aligns the key element on the central bore and, therefore,the positioning rod at a predetermined orientatation with respect to the apertures in the shell.

Title: Digital signal recording apparatus
Inventor: KIM SOON-TAE
IPC: G11B5/008
Filed: 1995-10-27
Abstract: In digital signal recording apparatus using I-NRZI modulation for recording, the need for intermittently reading or intermittently writing buffer storage is eliminated by using parallel-bit precoding to generate the channel words that are selected between for recording. The precoders perform precoding on an accelerated basis using ripple-through integration of the alternate successive bits used to form each channel word. Two precoders generate (n+1)-parallel-bit channel words at a channel word rate slower by a factor of (n+1) than the rate of a system clock for the I-NRZI modulation. This leaves additional time during each channel word interval to carry out a decision procedure, which determines which of the channel words generated by the two precoders is to be selected for recording. There is also sufficient additional time for completing a subsequent updating procedure, in which precoding information stored in the precoder that did not generate the selected channel word is altered, to conform to precoding information stored in the precoder that did generate the selected channel word. The parallel-bit channel words from the precoders are converted to serial-bit format for recording with a bit rate equal to that of the system clock. The parallel-bit channel words from the precoders are converted to serial-bit format with an effective bit rate that is substantially higher than that of the system clock, to provide signal for timely implementing the decision and updating procedures.

Title: Opto-electric-mechanical device or filter, process for making, and sensors made therefrom
Inventor: GUCKEL HENRY
IPC: G02B26/08
Filed: 1994-05-25
Abstract: This invention relates to devices and their applications which employ a resonant semiconductor member whose vibratory motion is coupled to the radiant energy cast onto a photovoltaic energy conversion device. It also relates to such devices whose vibratory behaviour is otherwise affected and which affect can be read optically. Optical methods are used to drive die microbeam, sense the microbeam vibrations and, if certain conditions are met, produce self-oscillation with no intervening electro-optical components, thus eliminating the need for piezoresistors, drive electrodes, electrical contacts and any metallurgy for electrical interconnection. A resonant microstructure member of one electrical type (p or n) is formed over a wafer, this member extending substantially or fully over a cavity or other space in the wafer. At a location in a wall or floor of the cavity is a region of opposite type (p or n) material. The interface between the two types is a p-n junction and is the best known form of a photovoltaic structure. The flexible member and the opposite type region should be substantially in the path of the driving radiant energy. The devices of this invention act as opto-electro-mechanically coupled photodiodes-causing the flexible member to be attracted electrostatically to the opposite type region by the incident driving light. The close proximity of the flexible member to the substrate or to an integrated cover or top cap forms a Fabry-Perot interferometer capable of producing large intensity modulations of the reflected light with small displacements of the member. A preferred form would have the vibratory member located within an evacuated capsule. The top cap would seal the member off on one side, and the wafer on which it was mounted or formed would seal the other. Applications as pressure sensor, accelerometer, acoustic ranger apparatus and temperature sensitive apparatus.
