Patent CA-2270650-A1 (CA)
Inventor: MOMBOURQUETTE MARK
IPC: A45D34/04
Filed: 1999-04-29
Abstract: A system for applying artwork to fingernails has a computer controller, a hand mold to securely hold the user's fingernails, a device for determining the size and location of the fingernails, and an applicator for applying the artwork. A  method for applying artwork to fingernails provides color and/or design choices selected from a computer media catalogue of colors and designs. A user views these choices on a video monitor, which also displays messages to guide the user through the application process. Prior to application of the artwork, the fingernails are coated with a light reactive base coat. The user's hands are inserted into a hand mold in which a height sensor and height gauge aid in positioning the fingernails at a preferred height position. The hand mold is retracted into a main system module in which an optical sensor detects the light reactive base coating for determining the size, peripheral shape, and location of the fingernails. A color applicator in the main system module applies the user selected artwork directly to the user's fingernails.

Title: Multiplex information network
Inventor: THANAWALA ASHISH A
IPC: H04J3/02
Filed: 1995-04-18
Abstract: A data multiplexing network is described which multiplexes a plurality of asynchronous data channels with an asynchronous data stream representing compressed voice signals and/or facsimile signals onto a single synchronous data packet stream. The single synchronous data packet stream is then transmitted by a high speed statistical multiplexes over a composite link to a second site using a modified high-level synchronous data link control protocol with an overlay of an advanced priority statistical multiplexing algorithm. The asynchronous data channels and the compressed voice channel and/or facsimile signals are demultiplexed and reconstructed for sending to other asynchronous computer terminals and to a standard telephone or facsimile analog port at the second site, respectively. PBX trunk interfaces are also provided to allow PBX's to share the composite link between sites. Communication between the first site by voice or facsimile and the second site is transparent to the users. The multiplexes efficiently allocates the bandwidth of the composite link by detecting silence periods in the voice signals and suppressing the sending of the voice information to preserve bandwidth. An advanced priority statistical multiplexes is also described which dynamically allocates composite link bandwidth to both time-sensitive and non-time-sensitive data to maximize data throughout efficiency and quality while simultaneously reducing multiplexes processing overhead.

Title: A structure for and method of mounting an object on a vertical surface and a laminated backing for such a structure
Inventor: BERENSON STEVEN C
IPC: A47G1/20
Filed: 1999-09-30
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.
