Patent CA-2272104-C (CA)
Title: Method for making a thin film resonant microbeam absolute pressure sensor
Inventor: HERB WILLIAM R
IPC: B81B3/00
Filed: 1997-12-29
Granted: 2008-11-18
Abstract: A micromechanical sensor having a polysilicon beam that is an integral part of the diaphragm resulting in a frequency of the beam that is a direct result of the pressure applied to the external surface of the diaphragm. Fabrication of this resonant microbeam sensor has no backside wafer processing, and involves a process and layout independent of wafer thickness for high yield and robustness. Both the diaphragm and resonant beam are formed from polysilicon. The sensor may have more than one resonant beam. The sensor beam or beams may be driven and sensed by electrical or optical mechanisms. For stress isolation, the sensor may be situated on a cantilevered single crystal silicon paddle. The sensor may be recessed on the isolating die for non-interfering interfacing with optical or electrical devices.
Patent CA-2273161-C (CA)
Title: Absorbent articles having lotioned leg cuffs
Inventor: SCHULTE THOMAS EDWARD
IPC: A61F5/44
Filed: 1997-12-03
Granted: 2003-04-08
Abstract: An absorbent article, such as a diaper, containing leg cuffs coated with a lotion composition is disclosed. The lotions disclosed in the present invention minimize the abrasion between the cuffs and skin in the area where the cuffs contact the wearer's skin, resulting in less skin irritation. The lotion compositions also reduce the adherence of BM to the skin of the wearer, thereby improving the ease of BM clean up. The lotion composition comprises a plastic or fluid emollient such as mineral oil or petrolatum, an immobilizing agent such as a fatty alcohol or paraffin wax to immobilize the emollient on the surface of the diaper leg cuffs, and optionally a hydrophilic surfactant to improve the processability and/or stability of the lotion compositions.  Because the emollient is substantially immobilized on the surface of the leg cuff, less lotion is required to impart the desired therapeutic or protective lotion coating benefits.

Granted: 2004-12-14
Abstract: A picture hanger is initially held in place on a wall in a temporary manner without damaging the wall by including a backing with a shock absorbing layer overlaid by a temporary adhesive film. Prior to the picture hanger being temporarily fastened to the wall, the temporary adhesive film is covered by a protective paper sheet. The shock absorbing layer prevents the wall from being indented when the hanger is permanently secured to the wall by hammering a pin or nail through the layer and film. The layer is sufficiently soft to hold the nail in place when the nail impales the layer prior to hammering the nail into the wall.      Prior to the backing being secured to the hanger, the permanent adhesive film is overlaid by another removable protective sheet.      Initially the backings are located on an elongated strip and are punched from the strip for mounting on the hook body.
