Abstract: A radiation imager includes a photosensor array that is coupled to a scintillator so as to detect optical photons generated when incident radiation is absorbed in the scintillator. The imager includes an optical crosstalk attenuator that is optically coupled to a first surface of the scintillator (that is, the surface opposite the photosensor). The optical crosstalk attenuator includes an optical absorption material that is disposed so as to inhibit reflection of optical photons incident on the scintillator first surface back into the scintillator along selected crosstalk reflection paths. The crosstalk reflection paths are those paths oriented such that optical photons passing along such paths would be incident upon photosensor array pixels that are outside of a selected focal area corresponding to the absorption point in the scintillator. The imager further may include an optical screen layer that is optically coupled to the scintillator second surface so as to be disposed between the scintillator and the photosensor array. The optical screen layer is made of a substantially transparent material selected to have a critical index of refraction so as to cause preferential reflection of optical photons that are incident on the screen layer to reduce optical crosstalk.

Granted: 2005-05-24
Abstract: A method of testing the assembled state of an internal combustion engine and quickly and accurately judging whether there is at least one fault with the assembling of the engine. While an exhaust-valve side space (100) is closed and a crank shaft (18) is rotated at a constant speed, the pressure in the exhaust-valve side space and the pressure in a surge tank (96) are detected by pressure sensors (106, 98), respectively. The assembled state of an engine (90) is tested based on the predetermined conditions of the detected two pressures. Those predetermined conditions may be the crank-shaft angles when the two pressures take respective maximal values, the crank-shaft angles when the two pressures change from their constant states to their increasing or decreasing states, etc. Based on those values, incorrect phases of crank and cam pulleys, incorrect clearances of intake and exhaust valves, missing of a compression ring, etc., can be identified.

Abstract: A lightweight orthopedic brace having no rigid structural elements is constructed from flexible material, and is designed primarily to provide for restriction of rotational movement and translation about the targeted joint by providing flexible bracing members (36, 76), which wind in a circumferential spiraling manner about a target joint (22) to provide active resistance to axial rotation and translation in the joint. Th e bracing members are adjustable to selectively increase the amount of resistance to axial rotation. The device may further comprise an undersleeve and/or an over-sleeve (66) to provide additional compression to the joint (22), and to facilitate the circumferential winding of the bracing members (36, 76). Construction of the orthopedic brace is such that resistan ce to rotation is achieved in both the internal and/or external directions. The orthopedic device has multiplicity of uses, including, but not restricted to prophylactic, post- injury/surgery, as well as proprioceptive and retraining functions.

Title: Using paging or satellite paging to trigger remote devices
Inventor: KRAML MARK H
IPC: H04W84/02
Filed: 2000-01-05
Granted: 2007-03-13
Abstract: The existing paging infrastructure is used to send commands to operate remotely located electronic or mechanical devices. A paging message containing one or more preset commands, trigger signals, or command strings is received by a paging receiver into an optional signal buffer which provides the received message to a message compare function. The message compare matches each component of the message to a set of one or more allowed commands and sends at least one signal or command that causes the action specified by the received message contents to take place at the target device. The command may be a signal for triggering an electronic or mechanical action, or may be a command that causes an operation to be performed in a software-controlled component of the target device. An alternate embodiment allows responses generated by the system and/or the target device to be forwarded back to the initiator via a two-way paging transceiver. The target device either has the capability of generating one or more signals or other messages in response to the commands received, or the system has the capability of sensing the state of the target device after receipt of the commands.  Responses generated by the target device may be sent to the optional signal buffer or directly to the paging transceiver, or may be received and modified by a response generation function that is part of the system. Responses may be relayed either at the completion of the execution of all the received commands or after the execution of any of the commands in a multi-command sequence, providing feedback to the initiator as the command sequence is processed. The initiator may also receive an indication of the success or failure of the entire sequence of operations, or may receive data or other information produced or collected by the target device.

Abstract: Procédé et dispositif de positionnement servant à limiter au maximum la durée nécessaire au déplacement d'un outil (4) le long d'une trajectoire continue, à savoir au-dessus d'un matériau transporté en continu sous cet outil. Cette trajectoire continue est discrétisée en déplacements géométriques, dont des paires sont, de préférence, réunies, afin de limiter les allées et venues du dispositif de positionnement. Des plages de vitesses sont analysées pour chaque déplacement discret et réglées de manière à se chevaucher afin de s'adapter à une courbe de vitesse continue. L'optimisation des plages de vitesses dans le but d'obtenir une accélération et une vitesse maxima de l'outil, a pour résultat un profil de vitesse d'outil optimisé dans la durée. On continue à optimiser les profils de vitesse de chaque déplacement discret afin d'augmenter l'accélération et la décélération, ce qui permet d'obtenir une vitesse maximum pour la majeure partie de la durée. Ce procédé permet de mesurer les effets de durée et de déplacement en incréments entiers. On exécute un arrondi et on règle les paramètres de mouvement de façon appropriée. Le dispositif (2) capable d'effectuer cette commande optimisée comprend des rails X parallèles (X1, X2) et un support mobile, dont chaque extrémité est commandée de façon indépendante. Des paliers permettent au support mobile de pivoter, la translation qui en découle étant absorbée par un autre palier à une des extrémités. Des codeurs optiques (6a, b, c) situés sur chaque rail X et sur le support mobile assurent un résultat de positionnement précis.

Abstract: A method and apparatus for producing an extruded product includes a machine that cooperates with an extruder. The machine is commonly used as a corrugator and the extruded product is often corrugated piping. The machine has a frame supporting a trackway in a continuous path. A plurality of mold block assemblies travel about the continuous path to form a mold tunnel along a portion of the continuous path. The mold block assemblies include a carriage connected by at least one guide and linear bearings to a pair of mold holders. The mold holders are connected to at least one pair of opposing mold blocks. Guides and directors position the mold block pairs relative to one another while the assemblies travel along the continuous path.      As the holders, and thus the mold block halves, are linearly displaceable from one another, the halves may meet to form the mold tunnel and separate to allow removal of the extruded product.
