Title: Image display apparatus
Inventor: KOGA RITSUO
IPC: G02B26/08
Filed: 1997-12-25
Abstract: An image display apparatus including an arc lamp as a white-light source, an ellipsoidal mirror for collecting a light beam from the arc lamp, a color filter for producing sequentially three primaries of light from the white-light beam, a condenser lens for allowing to be transmitted therethrough a light beam transmitted through the color filter, a single spherical mirror or non-spherical mirror for reflecting the light beam transmitted through the condenser lens, a digital micromirror device which receives the light beam reflected from the reflecting mirror and produces on and off states by varying the tilt of a micromirror of each of a number of two-dimensionally arrayed pixels to vary the angle of reflection of the light beam reflected therefrom, and a projection lens which enlarges and projects the light beam reflected from a pixel. The spherical mirror or non-spherical mirror is arranged such that the normal of the mirror at an intersection where the optical axis of an optical illumination module including the arc lamp, the ellipsoidal mirror and the condenser lens intersects the mirror is inclined by a predetermined angle.

Filed: 1998-10-14
Abstract: A printer system comprises a thermal printer, an ink transfer unit and a thermal printing unit.  The ink transfer unit and the thermal printing unit can be selectively mounted in the thermal printer.  The ink transfer unit has an ink reservoir in which liquid ink is stored.  The thermal printing unit has an ink ribbon.   When neither the ink transfer unit nor the thermal printing unit is mounted on the thermal printer, an image can be formed on a thermal recording sheet only by the thermal printer.          When the ink transfer unit is mounted on the thermal printer, ink stored in the ink reservoir is transferred onto a recording sheet to form an image thereon.  When the thermal printing unit is mounted on the thermal printer, ink contained in the ink ribbon is transferred onto the recording sheet.

Filed: 1996-04-29
Abstract: Low pH acidic compositions for chemical, pharmaceutical and cosmetic uses comprise two phases in solution. Phase I comprises about 2 to 98 weight % of several chemical, pharmaceutical and cosmetic substances. Phase II comprises about 2 to 98 weight % of an active aqueous acidic component having a pH value of less than about 1.

Title: Improved microphones for an implantable hearing aid
Inventor: LESINSKI S GEORGE
IPC: H04R25/00
Filed: 1997-05-23
Abstract: An implantable sealed microphone (50) includes a diaphragm (52) having a thin central region (54) surrounded by a thicker rim (56). One side of sheet electret material (72) is bonded to the diaphragm (52) while the other side contacts a roughened plate (82). The rim (56) is bonded to a housing (112) thereby hermetically enclosing the electret (72) and the plate (82). The microphone (50) also includes an electrical connector (94) that couples both the plate (82) and the electret (72) to an input of an amplifier (30) included in an implantable hearing aid system (10). Preferably, the microphone (50) is incorporated into a sealed electronics module (100) together with the amplifier (30) and an energy storage device such as a battery that energizes operation of the implantable hearing aid system (10). In such a configuration, the microphone's diaphragm (52) forms a surface of the electronics module's housing (112). An electrical connector (134) couples an output signal from the amplifier (30) to a microactuator (32) of the implantable hearing aid system (10).

Title: Genderless construction system
Inventor: CLEVER ERIC
IPC: A63H33/08
Filed: 1997-05-30
Abstract: A suite of construction toy systems in which mechanical connection is provided by hermaphroditic and functionally identical (genderless) connectors (30, 32). Both hub-and-rod (30, 32) and building-block (145, 160) construction toy systems are disclosed. In the hub-and-rod construction systems, the use of genderless connectors allows: rods (30) to connect directly to rods (30) by the same means rods (30) connect to hubs (32) (longer rods can be directly formed out of shorter rods); hubs (32) to connect to hubs (32) by the same means that rods (30) connect to hubs (32); and, in some assemblies hubs to be substituted for rods. An additional useful feature of the genderless connectors used and of the overall design of these toy systems is that many of the different construcion toy systems disclosed herein will inter-connect. By the application of this invention, a very wide range of very different and independent toy systems can be designed that freely inter-connect.

Patent CA-2260080-A1 (CA)
Inventor: TSUI BAN C H
IPC: A61M25/01
Filed: 1998-07-24
Abstract: Methods and systems for determining the proper placement of an epidural catheter prior to administration of anesthetic is described. In a preferred embodiment, an aqueous fluid is introduced into an epidural catheter that has been inserted into the spine of a subject. Motor reactions by the subject in response to electrical current applied through the aqueous solution is monitored. By monitoring the motor response with respect to electrical stimulation, the proper placement of an epidural catheter can be differentiated from the placement of the catheter in subarachnoid, subcutaneous or epidural intravascular placement. Additionally, in the preferred embodiment, a wire is disposed within the catheter tube to facilitate the passage of electric current. However, to avoid electrochemical reaction of the wire with the aqueous solution and/or the subject's dural tissue, the wire does not extend completely to the distal end of the catheter tube.

Title: Metatarsal safety guard for footwear
Inventor: BISSON MICHEL
IPC: A43B23/08
Filed: 1999-01-26
Abstract: A metatarsal guard for footwear comprises an arched body which covers a dorsal surface of a wearer's metatarsal foot area. The arched body has lateral bottom edges for engaging a footwear sole to transmit loads from the arched body to the footwear sole. Slits are defined in a rear portion of the arched body so as to form a longitudinally extending central T-shaped tongue and two longitudinally extending lateral tongues in order to increase the flexibility of the metatarsal guard. The T-shaped tongue has a rear edge extending in a concave curved line transversally of the footwear so as to prevent transmission of punctual loads to the wearer's foot. By optimizing the number and the configuration of the tongues, both the wearer's comfort and protection are maximized.
