Title: Electrical connector
Inventor: RICHMOND MARK A
IPC: H01R24/28
Filed: 1994-08-16
Abstract: ABSTRACT OF THE DISCLOSURE      An improved electrical connector for use in electronic assemblies to link electronic components in order to transmit electric signals or current.  The connector includes a wafer interface connective construction with at least one resiliently compressible contact to provide a means across which electrical current can flow from one male pin to another male pin without placing the pins in direct contact with each other.  The contact retains its form and resiliency through its non-compressive retainment within the aperture of the wafer interface connective construction.  Engagement and disengagement of the connector is facilitated, yet reliability and conductivity are enhanced.  Further, the size and weight of the connector is reduced, and the assembly of the connector is facilitated.  In addition, the pin contacts and the retainment components for the pin contacts are common to both halves of the connector which eliminates the need for socket contacts and their associated components.

Patent CA-2141688-A1 (CA)
Title: High overpressure low range pressure sensor
Inventor: LUTZ MARK A
IPC: G01L7/08
Filed: 1993-08-30
Abstract: A low range pressure sensor includes a base plate of brittle material, and a diaphragm plate assembly mounted on the base plate and sealed around a periphery to the base plate.  Pressures are introduced to cause a center diaphragm section to deflect toward the base plate, and the deflection of the diaphragm is sensed through strain gauges to provide an indication of the pressure.  The diaphragm is provided with a plurality of individual support posts on a side facing the base plate so that when the diaphragm is deflected toward the base plate under high over-pressures the support posts will support the diaphragm against movement to avoid failure or breakage of the diaphragm.  The number of support posts can be varied as desired.  In a preferred form of the invention, the base plate is provided with a very thin layer of silicon dioxide, which is a good electrical insulator and which also serves to help accomodate slight movement of the support posts as they touch the surface of the base plate to reduce stress buildup in the diaphragm as the overpressure increases.

Patent CA-2164993-A1 (CA)
Inventor: LI YUAN P
IPC: G02F1/01
Filed: 1995-12-12
Abstract: Integrated optical devices which utilize a magnetostrictively, electrostrictively or photostrictively induced stress to alter the optical properties of one or more waveguides in the device are disclosed.  The integrated optical devices consist of at least one pair of optical waveguides preferably fabricated in a cladding material formed on a substrate.  A stress applying material, which may be a magnetostrictive, electrostrictive or photostrictive material, is affixed to the upper surface of the cladding material near at least one of the optical waveguides.  When the appropriate magnetic, electric or photonic field is applied to the stress applying material, a dimensional change tends to be induced in the stress applying material.  The constrained state of the stress applying material, however, caused by its adhesion to the cladding material, causes regions of tensile and compressive stress, as well as any associated strains, to be created in the integrated optical device. By positioning one or more optical waveguides in a region of the device which will be subjected to a tensile or compressive stress, the optical properties of the stressed waveguide may be varied to achieve switching and modulation.  Latchable integrated optical devices are achieved by utilizing a controlled induced stress to "tune" one or more waveguides in an integrated optical device to a desired refractive index or birefringence, which will be retained after the field is removed.
