Patent CA-2050041-C (CA)
Title: Apparatus and method for supporting an accessory unit within an automobile storage area
Inventor: YASUKAWA NIHIKO
IPC: B60R11/02
Filed: 1991-08-27
Granted: 1996-11-19
Abstract: An apparatus and method is provided for the support of an accessory unit within the defined space of a storage area. The storage area is preferably a floor-mounted console receptacle or a dashboard receptacle commonly found within the seating compartment of an automobile. The support structure provides a mounting plate that supports a radio telephone unit within the receptacle by spanning the space separating side walls of the receptacle. Engaging Velcro attachment elements mounted upon both side flanges of the mounting plate and the receptacle side walls permits the mounting plate supporting the radio telephone unit to be easily installed or removed within the receptacle. The use of Velcro elements to removably install the mounting plate within the receptacle eliminates the need for fastening screws, nuts and bolts, or rivets to mount a support structure within the storage area. In an alternative embodiment, a support structure includes a U-shaped mounting bracket that supports an accessory unit within a dashboard receptacle. A pair of support arms, attached to a center connecting bar of the mounting bracket, are spaced apart by approximately the distance separating the space between receptacle side walls.     Upon inserting the mounting bracket within the receptacle, an angular tab located on each of the support arms engages one of the receptacle side walls and tends to act as a barb to frictionally retain the mounting bracket within the receptacle.          A projection located on either side panel of the accessory unit mates with a corresponding projection installation hole positioned on each support arm to removably install the accessory unit within the installed mounting bracket and thereby mount the accessory unit inside the receptacle. This eliminates the need for any fastening screws to install the accessory unit to either the mounting bracket or the face of the dashboard receptacle.

Title: Instantaneous vein entry indicator for intravenous needle
Inventor: MERSCH STEVEN H
IPC: A61B10/00
Filed: 1991-10-22
Granted: 1996-01-23
Abstract: A device  is provided for indicating when an intravenous needle has entered the vein through the use of a solid fiber optic mounted in the needle for showing visual instantaneous vein entry.   The distal  end of the fiber optic is polished to be flush with the distal point  of the needle.   The fiber  optic  is  sized  to have  an outer  diameter which  will  extend  through  the  cannula  of  the needle.  This polished distal end reflects color, such as red blood, immediately upon vein entry and exposure to blood to the magnifying system forming a part of the invention at the rear or proximal end of  the fiber  optic.   The user observes immediate vein entry without any blood flow or exposure to blood.  Other embodiments utilize the fiber optic as the needle, thus eliminating the needle itself.

Granted: 1998-07-07
Abstract: A fielf-aligning fastener system incorporates a stud member fastened to a first member and a female member attached to a second panel member for fastening the first member to the panel member.  The female member includes a head portion which spans an aperture of the panel and has an aperture therethrough, the head portion includes  leg portions which depend from the head portion which extend through the panel aperture and are engaged  by  a  clip  on  the  opposite  side  of  the  panel  for retaining  the  female  fastener  in  the  aperture.   The  panel aperture and leg spacing are dimensioned such that the female fastener is adapted to move along a first axis of said aperture thereby  allowing  the  female  fastener  to  accommodate  any alignment errors between itself and the stud fastener along the first axis.  The leg portions of the female fastener have a pair of  linear  engagement  surfaces  arranged  perpendicular  to  the first axis whereby the leg portions can engage and retain the stud member anywhere along their length.   This feature allows the fastener to accommodate alignment errors along a second axis perpendicular to the first axis.  The fastening system is also disclosed for use in a seat shell and seat insert assembly.

Title: Rate responsive pacemaker controlled by isvolumic contraction time
Inventor: CHIRIFE RAUL
IPC: A61N1/365
Filed: 1992-04-14
Granted: 2000-06-20
Abstract: A novel rate responsive pacemaker using isovolumic contraction time (IVCT) as a control signal responsive to metabolic demands is disclosed. This control signal is injected into the timing circuit of a standard rate adaptive pacemaker to enhance the pacer's ability to respond in direct relation to the patient's changing metabolic needs as he performs his daily activities.      A typical configuration using either right or left heart IVCT for rate control is described, in which the pacing rate is determined by the duration of IVCT. Since pacing rate and IVCT are linearly related, a simple conversion factor can be used to transform the duration of IVCT into the duration of the pacemaker escape interval (pacing rate). Although both right and left heart IVCT could be used for rate control, for the sake of simplicity only the right heart parameters are described herein.      The device is capable of operating in most of the available modes (WIR, DDDR, DDIR, AAIR), and has provisions for multiprogrammability, data storage, bidirectional telemetry, among other standard functions. The device has two inputs to measure IVCT: one, signaling the onset of mechanical activation of the ventricle (start of IVCT), and another, signaling the onset of ejection (end of IVCT). The time interval between these two signals is the duration of IVCT, which is processed by the pacemaker to determine the escape interval, through a simple conversion algorithm, analogous to what is available in the prior art. Onset and end points of IVCT are detected by any combination of biological sensors in the form of pressure, volume or flow transducers.
