Patent EP-0362366-A4 (EP)
Title: Instruction cache flush-on-rei control
IPC: G06F9/38
Filed: 1989-03-30
Abstract: A method and apparatus optimize the performance of a multiple cache system computer (Fig. 1) having separate caches for data (60) and instructions (50) in which all writes to the data cache are monitored. If an address tag of the item being written matches one of a list of tags (110) representing valid instructions currently stored in the instruction cache (50), a flag (120) called I-FLUSH-ON-REI is set. Until this flag (120) is set, REI (Return from Exception or Interrupt) instruction will not flush the instruction cache (50). When the flag (120) is set, an REI command will also flush or clear the instruction cache (50). Thus, the instruction cache (50) is only flushed when an address referenced by an instruction is modified, so as to reduce the number of times the cache is flushed and optimize the computer's speed of operation.

Patent EP-0562004-A4 (EP)
IPC: G01S15/89
Filed: 1991-12-13
Abstract: A multi-dimensional processing and display system is used with a sonar tracking system to monitor ocean-going vessels. The system arranges data in a three-dimensional matrix, which is then reformatted into a two-dimensional matrix. The two-dimensional matrix is decomposed into singular vectors and singular values. Certain data elements in the two-dimensional matrix are enhanced or diminished by modifying selected angular values. A history database is maintained by saving certain of the singular vectors, which is concatenated with the two-dimensional matrix. An enhanced two-dimensional matrix is generated by multiplying the two-dimensional concatenated matrix by the modified singular values and the singular vectors. After data enhancement, the two-dimensional enhanced matrix is reformatted back into a three-dimensional matrix. All or portions of the enhanced three-dimensional matrix can then be displayed.

Title: Constructional toy components.
Inventor: MADNER PETER
IPC: A63H33/04
Filed: 1993-08-27
Abstract: A constructional toy component (13) which has on at least one edge (11), two portions (15, 16) each of which has associated therewith one of two complementary members (19, 18), the arrangement being such that when two similar edges are brought into abutment but in the opposite sense, the complementary members (19, 18) can interengage if one of the components is initially flexed to effectively vary the spacing between the complementary members thereon. In one form of the invention, the edges are formed of rod like members and thus the component is basically defined by a peripheral frame. After engagement is completed, and the flexure is released, there is effectively no deformation of either component, but the components are held together by the interrelationship of the complementary members.

Title: A method and apparatus for performing minimally invasive cardiac procedures
Inventor: WANG YULUN
IPC: A61B19/00
Filed: 1997-02-19
Abstract: A system for performing minimally invasive cardiac procedures includes a pair of surgical instruments coupled to a pair of robotic arms with end effectors that can be manipulated to hold and suture tissue. The robotic arms are coupled to a pair of master handles by a controller to produce a corresponding movement of the end effectors. The movement of the handles is scaled such that the end effectors movement corresponds differently, typically smaller, than the movement performed by the hands of the surgeon. The input button allows the surgeon to adjust the position of the handles without moving the end effector, so that the handles can be moved to a more comfortable position. The system may include a robotically controlled endoscope allowing the surgeon to remotely view a surgical site. The surgeon may manipulate handles and move end effectors to perform a cardiac procedure.

Abstract: L'invention concerne un système miniature de réfrigération à base d'un mélange de gaz, ainsi que le procédé de fonctionnement de ce système. Un mélange optimisé de gaz est formulé à partir d'un groupe de fluides constituants, en fonction des propriétés thermodynamiques calculées d'un groupe de mélanges candidats de fluides. Le mélange de gaz est comprimé par un compresseur à une pression inférieure à 240 psia pour des raisons de sécurité. Ce mélange de gaz comprimé est mis en circulation à travers un échangeur de chaleur primaire, puis à travers un échangeur de chaleur primaire-à-secondaire, de manière à effectuer le refroidissement préalable du mélange de gaz. Le côté secondaire de l'échangeur de chaleur primaire-à-secondaire est refroidi par un système secondaire de réfrigération de Joule-Thomson. Des limitations de débits correctement dimensionnées du côté primaire de l'échangeur de chaleur primaire-à-secondaire peuvent solidifier et piéger des contaminants liquides éventuellement présents dans le mélange de gaz. Le mélange de gaz sortant par la sortie primaire de l'échangeur de chaleur primaire-à-secondaire circule vers un élément primaire de dilatation dans lequel le gaz sous pression élevée est dilaté de façon isenthalpique à une température inférieure égale à 183 K au moins. Ce gaz à basse température refroidit un élément de transfert thermique monté dans la paroi extérieure du cathéter, afin de refroidir un objet extérieur. Le gaz de retour recircule à travers l'échangeur de chaleur primaire, de manière à refroidir de nouveau préalablement le mélange d'arrivée de gaz sous pression élevée. On peut ajouter un échangeur de chaleur primaire distal entre l'échangeur de chaleur primaire-à-secondaire et l'élément primaire de dilatation.
