Inventor: SHICKEL ROBERT J
IPC: E04C2/20
Filed: 1990-03-13
Granted: 1993-06-29
Abstract: ABSTRACT OF THE DISCLOSURE         A laminated insulating material of the type utilizing at least two layers of insulation medium and in-cludes a third layer of closed cell plastic interposed between each insulation layer.  The air space created within the closed cells absorbs otherwise escaping thermal energy thereby reducing the amount of kinetic energy escaping out of the insulated environment.  The third in-sulation layer serves as a secondary barrier to absorb residual thermal energy passing through the plastic layer.       The arrangement of the laminated material increases the efficiency of the insulation as a thermal barrier thereby allowing it to operate more effectively in comparison to other known insulating materials.  An additional facing of one, two or three plies of sheet material may also be fixed to the outer face of the third insulation layer.

Title: Unitary intravascular defibrillating catheter with separate bipolar sensing
Inventor: BACH STANLEY M JR
IPC: A61N1/362
Filed: 1991-08-06
Granted: 1998-10-27
Abstract: A cardioversion system includes a bipolar sensing circuit with two sensing electrodes, and a cardioversion circuit with two spaced apart spring electrodes.  The sensing electrodes are spaced apart from one another but kept sufficiently close to one another for isolated, localized R-wave sensing.  The sensing electrodes further are positioned remotely of the cardioversion electrodes, to avoid post-shock abnormalities which otherwise would interfere with a timely R-wave sensing, to substantially prevent the discharge of an unnecessary cardioversion pulse after return of the heart to normal cardiac rhythm.  One preferred version of the system is a unitary catheter including a distal tip electrode and ring electrode as the sensing electrodes, and tow substantially larger, more proximal spring electrodes for defibrillation.  Alternatively, the defibrillation electrodes and the sensing electrodes can be provided on two separate catheters.          Yet another alternative involves providing one or more patch electrodes as defibrillation electrodes.

Title: Inking buffer for flat-panel display controllers
Inventor: COMERFORD LIAM D
IPC: G06F3/0488
Filed: 1991-11-29
Granted: 1996-01-02
Abstract: An intelligent subsystem separately supports inking functions in order to allow stroke-ignorant software to be  supported  in  a  stylus  driven environment.   This subsystem thus provides the inking capability missing in existing flat-panel display controllers.  Separate inking functions are incorporated into the subsystem in order to support inking management functions which do not corrupt the  display  refresh  buffer  as  it  is  understood  by existing application software.   The subsystem makes no assumptions about the application's awareness of stroke data  as  an  input  modality.   Instead,  the  subsystem assumes that a conventional display subsystem also exists in the system.  The subsystem utilizes the strobes and clocks generated by the conventional display controller to generate addresses in a memory which has physically separate  address  and  strobe  lines  from  the  display refresh buffer.  The content of this added memory is used to control the source of input to the data lines of the display.  The invention can be generalized to allow any number  of  planes  to  be  added  to  a  display  system providing access to that display system by any number of asynchronous processes such as inking.
