Title: A system for determining the spatial position and orientation of a body
Inventor: LEIS STEPHEN ELDON
IPC: G01S17/875
Filed: 1998-12-02
Granted: 2005-09-06
Abstract: A system for determining the spatial position and orientation of each of a plurality of bodies. Each one of the bodies has at least three markers in a predetermined, relative geometric relationship. The markers are adapted to emit energy in response to an activation signal and/or to reflect energy impinging ups such passive marker from an activatable energy source. A common energy detector is provided for detecting the energy emitted by the active marker and the energy reflected by the passive marker. A common processor is provided. The processor has a memory. The memory has stored therein the predetermined, relative geometric relation of the markers for each one of the bodies. The processor compares the stored predetermined geometric relation of the markers for each of the bodies with the energy detected by the energy detector to identify the bodies emitting, or reflecting the detected energy. With such an arrangement, a body can be tracked using a very simple sequence of operation in real-time with robust positive marker identification by taking advantage of a simple marker placement methodology. Multiple bodies can thereby be tracked simultaneously.

Abstract: L'invention concerne des articles absorbants, par exemple des serviettes hygiéniques et des protège-slips, qui sont respirants car ils comportent une feuille postérieure respirante et présentent, une fois humides, une faible tendance à mouiller les vêtements de l'utilisateur. Cette feuille postérieure comprend au moins une couche ajourée perméable à la vapeur, constituée d'un matériau non soluble, par exemple d'alcool de polyvinyle, rétrécissant au contact d'un liquide. Lorsque le matériau rétrécit au contact du liquide, les ouvertures de ladite couche ajourée se ferment, ce qui empêche le passage du liquide à travers la feuille postérieure et par conséquent vers le vêtement de l'utilisateur.

Abstract: The improved high performance muffler (12) is used to attenuate the sound waves in exhaust gases from internal combustion engines and the like and has a casing (14), which includes a closed volume defined by side walls, a top wall (16), a bottom wall (18) and inlet and outlet end caps (26, 28). The casing (14) also has a defined exhaust gas-flow passageway, which extends between the end caps (26, 28), which is bounded by upper and lower walls within the casing and the side walls, and which includes inlet and outlet chambers adjacent to the inlet and outlet end caps, respectively. Two spaced apart, gas-flow channels. A gas-flow director assembly (56), disposed between the side walls and the upper and lower walls, defines two spaced apart gas-flow channels. The gas-flow channels have a uniform, smooth cross section, and their lengths are substantially equal. The gas-flow director assembly (56) divides the exhaust gases flowing into the gas inlet chamber into two substantially unrestricted and equivolume gas streams, and also defines an intermediate chamber, which communicates with the gas-flow channels, intermediate their ends, so as to permit the exhaust gases flowing in the channels to expand and mix for sound attenuation. Perforations in the upper and lower walls permit sound waves in the exhaust gases to be attenuated in sound absorption materials (91, 102) disposed in the closed volume of the casing about the gas-flow passageway.

Abstract: Circuit structure and resulting circuitry for multiple-valued logic. The circuit structure allows the design and fabrication of any r-valued logic function of n-places where r is an integer greater than I and n is an integer greater than 0. This structure is called SUpplementary Symmetrical LOgic Circuit structure (SUS-LOC). In circuits incorporating SUS-LOC, circuit branches are realized that uniquely deliver circuit response and output. For some circuits, and due to the operating characteristics of the switch elements, additional circuit elements, or stages, must be incorporated to prevent "back biasing". SUS-LOC is fully active. Only active elements perform logic synthesis and those components not directly related to logic synthesis, such as resistors and/or other passive loads, are relegated the task of circuit protection.  The fabrication of r-valued, multi-valued, or multiple-valued logic circuits, designed using the definitions of the SUS-LOC  structure can be accomplished with known techniques, materials, and equipment.

Abstract: The invention features devices and methods for the systemic delivery of fentanyl or a fentanyl congener (e.g., sufentanil) to treat pain. In the present invention, a drug formulation comprising fentanyl or a fentanyl congener is stored within a drug delivery device (e.g., contained in a reservoir or impregnated within a matrix within the controlled drug delivery device). The drug formulation comprises an amount of drug sufficient for treatment and is stable at body temperatures (i.e., no unacceptable degradation) for the entire pre-selected treatment period. The drug delivery devices store the drug formulation safely (e.g., without dose dumping), provide sufficient protection from bodily processes to prevent unacceptable degradation of the formulation, and release the drug formulation in a controlled fashion at a therapeutically effective rate to treat pain. In use, the drug delivery device is implanted in the subject's body at an implantation site, and the drug formulation is released from the drug delivery device to a delivery site. The delivery site may be the same as, near, or distant from the implantation site. Once released at the delivery site, the drug formulation enters the systemic circulation and is transported to the site of action in the body to modulate the pain response (e.g., the brain or other pain sensory location).
