Title: Switch-based personal computer interconnection apparatus
Inventor: OLNOWICH HOWARD T
IPC: H04L12/18
Filed: 1993-06-23
Abstract: SWITCH-BASED PERSONAL COMPUTER INTERCONNECTION APPARATUS            ABSTRACT OF THE DISCLOSURE            Disclosed is a modularly expandable switch-based apparatus which is used to interconnect multiple Personal Computers as nodes  of  a  parallel  system.  The  invention  includes  a bus-based expansion card which is inserted into a card slot in each of the Personal Computers to provide an adaptation from the Personal Computer MicroChannel to the interface to a multi-stage switch network.  Thus, the disclosed invention provides   a   means   for   extending   the   MicroChannel architectures  to  either  massively  parallel  systems  or thousands of I/O device taps or a combination of the two.          This  is  accomplished  by  using  electronic  switches  to interconnect various Personal Computers, where each computer has a unique  local bus that can be composed of 1 to 8 MicroChannel   taps   (card   slots). An  expansion  card containing a bus architecture converter unit is used in one expansion card slot in each Personal Computer to adapt the node to the switch network.  The result is that the Personal Computers are fully interconnected and capable of sending data,  communications,  and/or  messages  between  any  two Personal  Computers,  which  become  nodes  of  the  parallel system.

Abstract: SYSTEM AND METHOD FOR AUTOMATIC RESOLUTION REDUCTION                 Abstract of the Disclosure A resource oriented host computer-printer system is disclosed in which the host computer and printer share information and data processing duties. A system and method for analyzing the execution times for draw primitives allows the host computer to determine whether the printer will be able to render draw primitives in real-time. A resource assembler calculates the cost of executing each draw primitive within a band to determine if the printer can render the draw primitive in real-time. If the band is too complex for the printer to render in real-time, the printer may pre-render the band or the host computer will render the band and transmit the bit-map of that band to the printer. The host computer makes a series of decisions as to the best form for transferring data from the host computer to the printer. If the printer cannot store the bit-map data file, the bit-map data file is compressed. If the printer cannot store the compressed bit-map data file, the host computer will reduce resolution in two stages, if necessary, until the printer can store the reduced resolution bit-map data file. The second stage of resolution reduction is guaranteed to fit within the printer. The host computer displays a message advising the user that the resolution has been reduced.     WW/MID)-7/3-519FF/V1

Title: Method and apparatus for generating multiphasic defibrillation waveforms based on pulse width ratios
Inventor: DREHER ROBERT
IPC: A61N1/39
Filed: 1993-09-24
Abstract: A method and apparatus for generating a multiphasic defibrillation/cardioversion waveform. The multiphasic defibrillation/cardioversion waveform is generated by specifying only the initial voltage and end voltage of the first phase and the percentage of time duration of each subsequent phase relative to the time duration of the first phase.

Filed: 1994-11-01
Abstract: A locking arrangement is provided for releasably locking door panels made of flexible material. The locking arrangement is adapted to be used on door panels of conventional vehicle shelters. The locking arrangement comprises a pair of generally hook-shaped locking members attached to the inner peripheral edges of the door panels.
