Abstract: A slide lock for a power return measuring tape including an elongated lock member having a resilient locking tongue extending longitudinally from a lower end of the lock member. Followers engage guide means in the housing for the measuring tape. The guide means includes a guiding surface formed by a ridge in each side wall against which the pins ride. The guiding surface defines a descending path to guide the tongue from a position above a measuring tape in the housing to a position in contact with the measuring tape. A lock surface is formed at a lower end of the guiding surface with a protrusion at a junction between the guiding surface and the lock surface. Movement of the pins over the protrusion to the lock surface forces the tongue in contact with the measuring blade and causes the tongue to bend to apply a clamping force to the measuring blade.

Title: Flexible light pipe for side-lit applications
Inventor: ABRAMOWICZ MARK ALLAN
IPC: B29C48/30
Filed: 1997-10-31
Granted: 2007-01-23
Abstract: An improved optical light pipe for side-lit uses is formed from a core/cladding combination, optionally with a transparent jacket, where the core is preferably a cured acrylic polymer and the cladding is preferably a fluorocarbon polymer containing a very low level of fine particles which scatter the light uniformly along the length of the piping. Further light enhancement can be obtained with low levels of glass fibers or glass microspheres also present in the cladding. Chopped glass fibers alone at low levels in the cladding are useful for back-lit applications. The light pipe so formed is useful in signs, underwater outlines, corridor lighting in theaters, and similar uses.

Title: Systeme therapeutique transdermique a identification exempte d'encres d'imprimerie et son procede de fabrication
Inventor: HORSTMANN MICHAEL

Granted: 2005-06-21
Abstract: L'invention concerne un système thérapeutique transdermique d'administration de principes actifs au corps humain à travers la peau. La couche de support de ce système est constituée de films plastiques stratifiés usuels en pharmacie, comportant une couche extérieure en matières thermoplastiques qui fondent à basse température et une couche face à la peau constituée de matières thermoplastiques qui fondent à une température plus élevée. La couche de support doit être pourvue d'une identification, par exemple appliquée par impression. L'impression avec des pigments ou des vernis pose toutefois des problèmes, étant donné que ces pigments ou ces vernis présentent des inconvénients à cause de leur toxicité, de la technologie à utiliser pour les appliquer et des prescriptions légales en matière de médicaments. Leur code d'identification est donc appliqué non pas sous forme d'une couche d'encre ou de pigment, mais sous forme d'une modification de la structure de la surface de la couche de support.

Abstract: The maximum wait time for callers in a call center (FIG. 10) is lowered by selecting, for an agent (25) who has just become available to handle a call, a highest-priority waiting call that would most likely wait the longest if it were not selected at this time. Anticipated wait times are computed for the calls at the heads of the non-empty highest-priority call queues that correspond to the agent's skills or splits (202-210). The anticipated wait time of a call is computed as the call's present (elapsed) wait time plus the average rate of advance of calls in the call's queue (210). The call with the longest anticipated wait time is then selected first and is assigned to the available agent for handling (212-216). The process is repeated each time that any agent becomes available.

Abstract: A method for multiplication of a point P on elliptic curve E by a value k in order to derive a point kP comprises the steps of representing the number k as vector of binary digits stored in a register and forming a sequence of point pairs (P1, P2) wherein the point pairs differed most by P and wherein the successive series of point pairs are selected either by computing (2mP,(2m+1)P) from (mP,(m+1)P) or ((2m+1)P,(2m+2)P) from (mP,(m+1)P). The computations may be performed without using the y-coordinate of the points during the computation while allowing the y-coordinate to be extracted at the end of the computations, thus, avoiding the use of inversion operations during the computation and therefore, speeding up the cryptographic processor functions. A method is also disclosed for accelerating signature verification between two parties.

Title: Registration control of mobile stations in a wireless communication system
Inventor: DIACHINA JOHN
IPC: H04Q7/36
Filed: 1996-10-18
Granted: 2006-04-11
Abstract: A method and device are provided for storing and maintaining parameters associated with activities relating to a first channel while a mobile station is camped on or uses a second channel. More specifically, when a parameter indicates that activities are to be executed, the mobile station returns to the first channel to execute the actions associated with the parameter. For instance, parameters associated with a DCCH may be stored when the mobile station moves from the DCCH to a packet data channel (PDCH). When a parameter indicates that activities are to be executed, the mobile station may then return to the DCCH  from the PDCH and execute the actions associated with the parameter. Since the mobile station returns to the DCCH for the actions rather than staying on the PDCH, the mobile station is activated from a system perspective, on both channels.

Abstract: Apparatus for producing plastic film, of the type in which molten plastic is extruded through an annular die to form a tubular bubble which is expanded by air blown into the bubble, and a collapsing frame for forming the bubble into a flat tube prior to passing the tube through a nip formed between rollers, in which opposed, converging reaches of endless belts are used for the collapsing. The belts have their upstream ends held by a pair of first rollers spaced apart on opposite sides of the bubble, and have their downstream ends held by a pair of nip rollers which hold the belts together to form a nip for the collapsed tube. Pulleys and a belt, or gears, are provided which rotatably interconnect the pinch rollers and ensure that the belts entering the nip travel at the same surface speed.

Granted: 2006-08-22
Abstract: A multivoltage (120 VAC to 277 VAC) input, low leakage current type, microcontroller-based, wall switch mounted, IR motion sensor with a latching relay having zero watt load switching capability, provided in a low cost, single PC board design to be mounted in a single gang electrical box. The switching circuit delivers AC electrical power to a load, such as a lighting fixture, from an AC power supply having only a hot lead, a neutral lead and a ground connection.      The switching circuit comprises a rectifier, coupled to conduct a leakage current between the hot lead and the ground connection, for converting the AC electrical power to a DC electrical power supply. A relay has a first normally open contact coupled to the hot lead and a second normally open contact coupled to the load, and is powered by a storage capacitor. An IR occupancy sensor generates a signal in response to a detected human presence. A digital microcontroller is coupled to the DC electrical power supply, the relay, and the occupancy sensor, and controls operation of the relay to selectively deliver electrical power to the load. The switching circuit also includes a power monitor section, a power reset section, a power relay section for operating the relay switch, an LED flash section, and a timer section.
