Title: Stretch-activated elastic composite
Inventor: SUZUKI MIGAKU
IPC: D04H13/00
Filed: 1995-01-17
Abstract: A stretch-activated elastic composite (20A, 20B) comprising: a non-woven fabric (21, 22) having a potential elongatability of higher than 100 % in a predetermined direction, and an elastically recoverable, elastic sheet (11, 12). The elastic sheet in its unstretched state is partially bonded to the non-woven fabric in its unelongated state. The elastic composite exhibits, per unit width of 5 cm: a stress of lower than 1000 g at 30 % stretch; a stress of higher than 400 g at 100 % stretch; a breaking point of higher than 400 g and an elastic limit of higher than 200 %. The elastic composite after being stretched at a rate of lower than 200 % exhibits, per unit width of 5 cm: a stress of lower than 500 g at 30 % stretch and a stress of higher than 100 g at 100 % stretch. The elastic composite after three repeated cycles of 150 % stretching and relaxing exhibits an elastic recovery rate of higher than 60 %. The elastic composite of the present invention provides excellent performance in elastic recovery and a soft surface touch to a human skin, and is best utilized in elasticizing an article portion which is brought into direct contact with the human skin.

Patent CA-2180518-A1 (CA)
Inventor: MEDVED JAN
IPC: H04L12/56
Filed: 1996-07-04
Abstract: A loopback mechanism uses frame relay OAM loopback frames which eliminate the need for location identifiers and reduces overhead and complexity. The frames replace source and destination loopback location identifiers by a loopback indicator field, a send node count field and a return node count field. The originating node of the loopback procedure sets the number of intermediate frame relay nodes to be traversed. The intermediate frame relay nodes simply increment or decrement the node count, depending on the direction of the loopback frame.

Title: Device for the identification of acne, microcomedones, and bacteria on human skin
Inventor: MARGOSIAK MARION LOUISE
IPC: G01N21/64
Filed: 1996-09-24
Abstract: The invention relates to a device and a method for the identification of fluorescing follicles that can be follicular impactions and/or microcomedones (clinically non-evident acne lesions), and/or comedones (clinically evident acne lesions) and/or bacteria on the face or other skin surface area. The inventive device allows thedetection of both types of follicular fluorescence (yellow/green and orange/red). For safety reasons, to prevent skin burns and erythema, the filter on the ultraviolet light source removes substantially all the harmful UVB radiation (280-320nm wavelengthrange). The filter used in conjunction with the detection means removes reflected and scattered light emanating from the subject's skin surface, thus increasing the sensitivity and discretion of the technique and making fluorescence detection easier and clearer.

Title: A voltage clamped parallel resonant converter with controllable duty cycle
Inventor: LAUW HIAN K
IPC: H02M3/335
Filed: 1995-07-11
Abstract: A high efficiency static voltage clamped parallel resonant converter for converting power between two AC and/or DC circuits includes a link circuit (30) between an input switch circuit (20) and an output switch circuit (10).  The link circuit comprises a parallel resonant circuit and link switch elements (Sc1 and Sc2) which are switched to generate a unipolar train of link voltage pulses. All of the switches are "soft-switched" on and off at substantially zero voltage or zero current. Each link voltage pulse consists of a zero segment and a non-zero segment. The duty cycle of these voltage pulses is controllable by the link switches and such that the duration of the zero and non-zero segments are independently controllable. Pulse width modulation (PWM) and pulse area modulation (PAM) can be applied for reduced filtering requirements and maintaining high efficiency for operation at fractional load conditions. The link voltage is clamped to a maximum voltage during the non-zero segment of each link voltage pulse. Resonant oscillation due to the resonant circuit is active only during the transitions between the zero and non-zero voltage levels of the link voltage pulses. As a result, all converter components will be exposed to voltage and current levels which are higher than the load voltage and current levels by just a small fraction.
