Title: Absorbent article having a topsheet that includes selectively openable and closable openings
Inventor: NAKAHATA HIROSHI
IPC: A61F13/511
Filed: 1998-10-26
Abstract: An absorbent article adapted to be worn about the lower torso of a wearer. The article includes a liquid-impervious, flexible backsheet adapted to face outwardly relative to the body of a wearer, a liquid-pervious topsheet adapted to face the body of the wearer, and an absorbent core positioned between the backsheet and the topsheet. The topsheet is elastically extensible and includes a plurality of slits or cuts that extend through the topsheet material and that enlarge to define a plurality of openings in the topsheet when it is subjected to tensile forces as it is worn. The openings permit solid and semi-solid bodily exudates to pass through the topsheet to the absorbent core as the diaper is worn. Upon removal of the diaper from the body of the wearer the tensile forces within the topsheet are relaxed, thereby causing the openings in the topsheet to close and substantially conceal from view the bodily exudates that had passed through the topsheet.

Patent CA-2336728-A1 (CA)
Inventor: KOLSRUD ARILD T
IPC: H03M1/18
Filed: 2001-02-14
Abstract: An analog-to-digital converter (ADC) includes a dither signal generator configured to add an analog dither signal to the analog input signal of the ADC prior to digitization (i.e., quantization). The amplitude of the dither signal is selected based upon the power levels of one or more carriers present in the bandwidth for which the ADC is designed to operate. Addition of the dither signal to the input signal in the analog domain reduces quantization noise such as conversion spurs that result from non-linearities in the ADC transfer function.

Title: Microelectromechanical actuators including driven arched beams for mechanical advantage
Inventor: WOOD ROBERT L
IPC: H01H61/02
Filed: 2001-03-14
Abstract: Microelectromechanical actuators include a substrate, spaced apart supports on the substrate and a thermal arched beam that extends between the spaced apart supports and that further arches upon heating thereof, for movement along the substrate. One or more driven arched beams are coupled to the thermal arched beam. The end portions of the driven arched beams move relative to one another to change the arching of the driven arched beams in response to the further arching of the thermal arched beam, for movement of the driven arched beams. A driven arched beam also includes an actuated element at an intermediate portion thereof between the end portions, wherein a respective actuated element is mechanically coupled to the associated driven arched beam for movement therewith, and is mechanically decoupled from the remaining driven arched beams for movement independent thereof. By allowing independent movement of the actuated elements, a variety of actuator applications may be provided wherein it is desired to actuate multiple elements in the same or different directions. For example, first and second driven arched beams may extend parallel to one another, such that the actuated elements that are mechanically coupled to the first and second driven arched beams move in a same direction by the further arching of the thermal arched beam. In other embodiments, the first and second arched beams arch away from each other, such that the actuated elements that are coupled to the first and second driven arched beams move in opposite directions by the further arching of the thermal arched beam. In yet other embodiments, the first and second driven arched beams arch toward one another, such that the actuated elements that are mechanically coupled to the first and second driven arched beams move in opposite directions by the further arching of the thermal arched beam.

Abstract: An assay for the presence of luciferase in a biological sample offers heightened sensitivity, signal intensity and persistence. The assay is sensitive down to 50 fg luciferase. The biological sample is combined with essential ingredients luciferin, ADP, myokinase and Mg++. The myokinase converts ADP to ATP, necessary for the luciferase reaction, and AMP, which retards the reaction kinetics. The resulting assay exhibits a persistent glow emission which makes it adaptable to automation.

Title: System for directly venting odour air from toilet bowl
Inventor: MIN KIM HONG
IPC: E03D9/05
Filed: 2001-05-11
Abstract: An air ventilation system is provided for removing obnoxious odour air directly from a toilet bowl. The system includes a portal vent formed at the rear underside of the toilet seat. A lateral tube is mounted to the hinge brackets for pivotally mounted the toilet seat to the toilet bowl. The lateral tube has an air inlet opening which is aligned with the portal vent when the toilet seat is at the down position to form an air flow channel. The portal vent and the air inlet opening are offset with one another when the toilet seat is at the up position thus closing the air flow channel to prevent water from overflow or splash to enter into the system. The air flow channel is coupled to a fan for drawing the odour air to the outdoor. A rubber gasket is mounted at the underside of the toilet seat to provide a perfect air seal between the seat and the toilet bowl.

Abstract: A shutter louver control bar which is made from a resilient plastic material includes an elongated bar member with a plurality of louver attachment members spaced from one another lengthwise along the bar member. Each attachment member, which normally assumes a louver attachment position, and which is moveable to a louver insertion position, has a leg with base leg part extending from the bar member, an outer leg part extending from and aligned with the base leg part and a head portion transverse to both the outer leg part and the base leg part when the attachment member is in the louver attachment position. The outer leg part is more flexible than and bendable relative to the base leg part which enables the attachment member to be moved to the louver insertion position where the head portion of the attachment member is at least somewhat generally aligned with the base part while remaining at generally transverse of the outer leg part of the attachment member. The plastic material of the attachment member has sufficient memory to cause the outer leg part to realign with the base leg part in moving the attachment member away from the louver insertion position back to the louver attachment position.

Abstract: Directional Ad® or D-Ad® is the Advertising Spot that is pitched by the Road and Street name signs. The street name signs are the signs that bear the names of the Streets, Avenues, Boulevards, Crescents, Courts, Roads, Place, Park, Parkway, etc., while the road signs are the Interstate and Intrastate Highways, etc. These spots being identified as the side of roadway, and streetname signs plates, are vantage positions with high number of visibility to traffic on a daily, minute, and hourly basis. The name given to this innovative idea is Directional Ad® or D-Ad®.      Features of D-Ad® R Visibility - It is and will be visible to anyone that needs to look for a street name or address, and to all the hiway users. R Spot Specific - It is spot specific, in the sense that the ad will be placed at the edge of the street name plates as shown in the later part of this document. R Easy to Install - The D-Ad® is easy to install to the existing plates.  There are three suggested ways to do this: 1. By screwing to the edge of the existing street name plates 2. By pasting as a sticke the edge of the existing street name plates 3. By spot allocation on boards through enlargement of such boards from normal sizes to such sizes required to accomodate the size of the D-Ad® R Non-Obstructive - The D-Ad® is non-obstructive, because it does not overlap the existing street or direction name plate. R Informative - The D-Ad®s help to inform the general public about the company whose logo or name is occupying the spot, their products and or services. It could serve as reminders to others who on seeing the D-Ad®s immediately remember getting a company's products or requesting the company's services. R Safe - The size of the D-Ad® is of proportional size to the street name plate
