Abstract: In producing digital signal processors generation of behavioral models (18) is used. Such a processor is constituted of hardware modules like computational units and a control unit. The behavioral model (18) is a description of the processor hardware and the program to be executed by the processor, the model being in executable program code written in a HLL programming language. First an architecture of the processor or parts thereof is determined (1) using predetermined templates (17). A layout description of the corresponding circuit is made (21) based on the determined architecture, this layout description being used to produce the layout of the corresponding circuits, so that a semiconductor chip can be processed according to the layout. When making a layout description of a processor part the structure of the processor or part thereof is coded in a textfile (3) as definitions of variables and operations and/or functions which are to be performed using the variables as arguments. These definitions are interpreted (21) to form the respective registers and units performing the functions and lines connecting the registers and the units. The textfile (3) is also used for making the behavioral model (18) that in turn can be used for simulating (18) the processor. A very rapid way of constructing adapted signal processors is obtained hereby, the method being used by a circuit designer interactively with computer software.

Inventor: VEKSELMAN ALEXANDER MAXOVITCH
IPC: G03F7/038
Filed: 1996-10-11
Abstract: Solvent-processable chemically amplified resists have a photoresist layer on a substrate; the layer comprises a solvent-soluble, non-light scattering film of polymer which bears vicinal dicarboxylic acid or monoesterified dicarboxylic acid groups, and a photoinitiator as a source of acid catalyst; the dicarboxylic acid or ester groups are acid catalyzably dehydrated or dealcoholated by the acid catalyst to acid anhydride groups which render the polymer insoluble, in a solvent in which the original polymer is soluble, or soluble in a solvent in which the original polymer is insoluble. The resist is exposed in an image-wise manner, for example, to UV radiation which results in release of the acid catalyst in the exposed areas; on heating, the acid catalyzes the dehydration or dealcoholation of the dicarboxylic acid or ester groups to acid anhydride groups whereby an image is defined by solventinsoluble and solvent-soluble zones of the layer. Alternatively a reverse image is defined if the resist is first thermally dehydrated or dealcoholated, then exposed, then rehydrolyzed or alcoholyzed in exposed areas. This system enables the use of water and/or alcohol developers in many cases.

Title: Application programming interface for data transfer and bus management over a bus structure
Inventor: SMYERS SCOTT D
IPC: G06F13/10
Filed: 1997-01-29
Abstract: An application programming interface implements and manages isochronous and asynchronous data transfer operations between an application and a bus structure. During an asynchronous transfer the API includes the ability to transfer any amount of data between one or more local data buffers within the application and a range of addresses over the bus structure using one or more asynchronous transactions. An automatic transaction generator may be used to automatically generate the transactions necessary to complete the data transfer. The API also includes the ability to transfer data between the application and another node on the bus structure isochronously over a dedicated channel. During an isochronous data transfer, a buffer management scheme is used to manage a linked list of data buffer descriptors. This linked descriptor list can form a circular list of buffers and include a forward pointer to the next buffer in the list and a backward pointer to the previous buffer in the list for each buffer. The linked descriptor list may also form a linear list to which the application can append additional buffers or remove existing buffers from the list. During isochronous transfers of data, the API  provides implementation of a resynchronization event in the stream of data allowing for resynchronization by the application to a specific point within the data. Implementation is also provided for a callback routine for each buffer in the list which calls the application at a predetermined point during the transfer of data.

Title: Intrathoracic cardiac compression
Inventor: PARSONS WILLIAM R
IPC: A61M60/468
Filed: 1997-06-18
Abstract: Trans-esophageal cardiac compression is performed during cardiopulmonary resuscitation by introducing into the esophagus a tube (12) having a distal inflatable member, such as a balloon (20). The balloon (20) is positioned in the esophagus (48) at the level of the ventricles of the heart (50). A rapidly cycling pump (16) (such as a compressible bag) is attached to the tube (12), and used to inflate and deflate the balloon (20) on the tube (12). As the balloon (20) inflates, it compresses the ventricles against the sternum (54), increases the transmural pressure across the ventricular wall, and propels blood out of the heart (50) into the aorta and pulmonary arteries. The balloon (20) is inflated and deflated at a rate of approximately 60 cycles to 80 cycles per minute to maintain perfusion of the heart, brain and other vital organs until more definitive therapy can reestablish the contractile activity of the heart. The balloon (20) can be inflated and deflated by a handheld pump (16), or by a rapidly cycling gas pump (100). A particular embodiment of the pump includes a larger volume pump that is driven by a smaller volume drive pump which cycles rapidly to force gas into and out of the balloon

Abstract: A pipe stem for a modular smoker's pipe of the dry bowl type is disclosed which has four modules to which a bowl assembly can be attached. The pipe stem has four separate modules; 1) the shank which is cylindrical and hollow in form; 2) an elongate bit (bit) which is also hollow and which serves as the mouthpiece of the pipe; 3) a shank insert having an upper hole through which smoke is allowed to pass and a lower hole through which liquid is allowed to pass; and 4) an elongate bit insert (bit insert) fashioned in much the same manner as the shank insert; however, the bit insert has an axially extending hollow tube at one end, whereby the tube has an outer wall with a shape, size and configuration such as to be removably insertable in said shank insert. The shank insert and the bit insert, which both fit inside the shank and the bit respectively, resist the tendency to rotate inside the shank and the bit through the use of a keyway. The outer surface of both inserts has two grooves running along opposite sides of the insert which will accept corresponding ridges (keys) on the inner surface of the shank and the bit. Modules in previous modular smoker's pipes are intricate and difficult to manufacture.  The present invention retains all of the advantages of a dry bowl smoker's pipe while reducing the difficulty of manufacturing.
