Title: Dynamic work zone safety system
Inventor: KLASHINSKY ROD
IPC: G08G1/081
Filed: 2001-04-06
Granted: 2006-12-05
Abstract: A novel dynamic work zone safety system and method of traffic control for a construction work zone are provided herein. The system includes a first traffic signalling device which is positioned along a roadside immediately upstream of a point where traffic is diverted to a single lane. The first traffic signalling device is defaulted to flash a suitable warning, e.g., "DO NOT PASS" or "MERGE LEFT" or "MERGE RIGHT", thereby to provide a first "NO PASSING" or "MERGE LEFT" or "MERGE RIGHT" zone which is defined by the distance between the first traffic signalling device and the end of the work or construction zone. A second traffic signalling device is positioned alongside a roadside a predetermined distance upstream of the first traffic signalling device. The second traffic signalling device defaulted not to flash a suitable warning, e. g. , "DO NOT PASS" or "MERGE LEFT" or "MERGE RIGHT" . However, when activated (by processor-controlled means defined herein) to flash a suitable warning, e.g., "DO NOT PASS" or "MERGE LEFT" or "MERGE RIGHT", the second traffic signalling device provides a second suitable zone, e.g., a "DO NOT PASS" or "MERGE LEFT" or "MERGE RIGHT" zone which is contiguous to the first "NO PASSING" or "MERGE LEFT" or "MERGE RIGHT" zone. This lengthens the "NO PASSING" or "MERGE LEFT" or "MERGE RIGHT" zone between the second traffic signalling device and the end of the work or construction zone. A plurality of spaced-apart sensors, preferably non-invasive sensors, is disposed along the roadway both downstream of, and upstream of, the second traffic signalling device. These sensors detect and determine the length of a traffic queue upstream of the first traffic signalling device between the first traffic signalling device and the second traffic signalling device, and provides a signal which is representative of the length of the traffic queue. The processor receives the traffic queue signal and generates a first activation signal to activate the second traffic signalling device when the traffic queue reaches a predetermined length. It also generates a first deactivation signal to deactivate the second traffic signal when the traffic queue is less than the predetermined length. This dynamically increases or decreases the "NO PASSING" or "MERGE LEFT" or "MERGE RIGHT" zone.

Title: Packaging device for attachment of clips to a continuously moving tube of casing
Inventor: MAY DENNIS J
IPC: B65B9/12
Filed: 1999-10-01
Granted: 2008-03-11
Abstract: An apparatus for attaching shaped metal clips at intervals to viscous-product-filled casing includes a support frame, a clipper assembly, a clipper assembly mounting rail, and a clipper assembly reciprocation mechanism. The clipper assembly is reciprocally mounted for reciprocal movement back and forth between a first casing entry station and a second casing exit station. A  continuous tube of filled casing enters the apparatus at the first station and exits at the second station. The clipping assembly includes a filled casing support passage. Filled casing is directed through this passage as the casing extends between the first and second stations. The clipper assembly further includes first and second casing gathering plates which are projectible into the passage to gather the filled casing to form a neck station therein. The neck section is for attachment of at least one clip about the casing. In the region between the first and second stations, the tube of casing is clipped by the reciprocating clipper assembly, which further includes a clipper mechanism for attachment of clips about the gathered casing.

Abstract: L'invention se rapporte à un afficheur optique comportant au moins une première et une seconde pluralité de sources optiques (200, 300), chacune de ces sources pouvant être de préférence un ensemble de lasers à semi-conducteurs, lesdites sources délivrant une pluralité de faisceaux laser sur un chemin optique permettant leur réflexion par des facettes réfléchissantes (204, 304) d'un réflecteur mobile (32) et l'éclairage d'un écran d'afficheur (206). Dans un afficheur couleur, chaque colonne de l'ensemble laser correspond à une couleur primaire distincte. Les rangées distinctes de chaque ensemble correspondent à des lignes de balayage activées indépendamment mais commandées simultanément qui doivent être éclairées par l'appareil de balayage à faisceaux laser. La pluralité d'ensembles à faisceaux laser divise la largeur de l'écran en segments de balayage de dimension inférieure de manière à accroître l'angle de balayage ou à accroître la vitesse de balayage horizontal de l'appareil. Des facettes obliques illuminent différentes sections verticales de l'écran avec les faisceaux laser lorsque le réflecteur est en rotation. Un format de balayage utilisant des pavés de balayage en diagonale, éclairés de manière simultanée, permet une utilisation optimale de la pluralité d'ensembles à faisceaux laser.

Title: Recirculating shade tree blender for a graphics system
Inventor: DREBIN ROBERT A
IPC: G06T15/00
Filed: 2001-08-17
Granted: 2010-05-04
Abstract: A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. To achieve multi-texturing, conventional graphics rendering systems typically rely on multiple rendering passes or require multiple serial/parallel texture-retrieval/processing circuits which occupy additional chip real-estate and exacerbate memory arbitration problems. To solve this problem and to provide an enhanced repertoire of multi-texturing capabilities, a relatively low chip-footprint, versatile texture environment (TEV) processing subsystem is implemented in a pipelined graphics system by utilizing a flexible API and a hardware-accelerated programmable texture blender/shader arrangement that circulates computed color and alpha data over multiple texture blending/shading cycles (stages). The texture-environment subsystem combines per-vertex lighting, textures and constant (rasterized) colors to form computed pixel color prior to fogging and final pixel blending. Blending operations for color (RGB) and alpha components are independently processed within the TEV subsystem by a single sub-blend unit consisting of a set of color/alpha-combiner (shader) hardware that is reused over multiple processing stages to combine multiple textures. A set of four selectable current-color input/output registers which are shared among all stages is provided at the output of the sub-blend unit to temporarily store computed color results and to pass computed color between stages. Arguments for blending stage operations can be selected from: the four current-color registers, rasterized color (diffuse or specular), texture, the alpha components of the above colors, and 0 or 1. Up to sixteen independently programmable consecutive stages, forming a chain of 78 blending operations, are supported for applying multiple textures to a single object in a single rendering pass.

Title: Infant drinking cup
Inventor: MEYERS BRENDA JEAN
IPC: G01F23/22
Filed: 2001-11-28
Granted: 2010-08-03
Abstract: An infant drinking cup is described. The infant drinking cup is a first color when at room temperature. When the cup is filled with a cold beverage, the portion of the cup below the fill line changes to a second color. When handled by an infant, those areas below the fill line in contact with the infant's warm hands change color back to the first color. The process is fully reversible, such that the infant drinking cup can change from the cold color to the warm color, and vice versa, repeatedly.

Abstract: Cette invention concerne une tuyère à injection tangentielle embarquée (TOBI) ou une tuyère à injection radiale (ROBI) à zone de flux réglable dans un moteur à turbine à gaz, permettant de diriger un flux d'air de refroidissement dans un ensemble rotor de la turbine. Cette tuyère est une structure moulée comprenant une pluralité de passages d'air de refroidissement tangentiels, certains d'entre eux étant moulés fermés. Après un essai de flux, un ou plusieurs de ces passages moulés fermés peuvent être ouverts par usinage. Par conséquent, cette structure est fabriquée facilement par un processus de moulage à faibles coûts de fabrication alors que le flux optimum d'air de refroidissement est obtenu par un réglage de la zone de flux total de la tuyère avant qu'elle ne soit installée dans le moteur à turbine à gaz. La tuyère est en outre positionnée à faux pour éviter les contraintes thermiques. La zone de flux réglable permet aussi une utilisation de cette tuyère sur différents types de moteurs.
