Abstract: Systems, methods and computer program products are provided for testing whether Web content has been properly tailored by a transcoding proxy for display within various requesting pervasive computing devices. Simulated HyperText Transfer Protocol (HTTP) requests are built using information from one or more data files. Each simulated request includes a Uniform Resource Locator (URL) that identifies a location of Web content. Each simulated request also includes an HTTP header containing information about a respective pervasive computing device. Simulated HTTP requests are asynchronously issued to respective Web servers identified in the respective HTTP requests. An HTTP response to each respective simulated HTTP request is received and includes Web content tailored for display within a respective pervasive computing device associated with the respective simulated HTTP request. Each HTTP response is then compared with an expected HTTP response. An HTTP response that does not compare favorably with an expected HTTP response can be saved for later analysis.

Title: Method and system for distributing subscriber services using wireless bidirectional broadband loops
Inventor: TWEEDY ERNEST P
IPC: H04W4/00
Filed: 1999-01-20
Granted: 2009-08-04
Abstract: A method and system for distributing subscriber services to a number of user locations in a broadband cellular network (100). A bidirectional antenna array located at a number of cell centers (200, 202, 204) provides coverage over a wide service area by using wireless distribution loops (140). The cell centers (200, 202, 204) broadcast subscriber services over designated channels and a user at the subscriber site location commands a centralized mechanism to switch to the channel broadcasting the requested service. The duplication of service channels is minimized and the number of subscribers is maximized by allowing channel selection to occur at various points in the distribution network. Each antenna in the array is configured to provide the subscriber service to a particular service segment. These segments include subscriber location sites with processing equipment to request and receive the services in the form of information programs, data, signaling, etc.

Inventor: HASSLER ULF
IPC: G01M17/02
Filed: 1999-08-12
Granted: 2005-04-12
Abstract: A device for the contactless detection of a potentially existing essentially edge-free irregularity in a convex surface, which has a structuring that is delimited by edges, comprises a unit (10) for creating a three-dimensional representation of the surface, a unit (20) for extracting the convexity from the three-dimensional representation of the surface and for smoothing the edges of the structuring so as to obtain a convex-free representation of the convex surface which exhibits the irregularity and the structuring, whose edges have now been smoothed, a unit (30) for comparing the convex-free representation with a threshold value so as to identify areal regions of the convex-free representation which are determined by a predetermined relationship to the threshold value, and a unit (40) for analyzing the areas of the identified regions (50a, 50b), a region (50b) being detected as an irregularity if its area exceeds a predetermined area. When this device is used to carry out quality control of tires, bulges or constrictions can therefore be identified with certainty in real-time operation and can be distinguished from an inscription or marking which has been intentionally provided on the tire.

Granted: 2005-10-11
Abstract: A split ring is disposed on an inner wall of a gas turbine casing. The split ring is composed of a plurality of split segments that are arranged on the inner wall of the casing in circumferential direction. A predetermined clearance is formed between the inner face of a split segment and the rotor blade tips. The split segments are arranged so that a predetermined circumferential clearance is formed between the split segments in order to allow the thermal expansion of the segments. A circumferential end face located upstream side of the segments with respect to the direction of the rotor blade rotation is connected to the inner face by a transition face having a surface foamed as an inclined plane. The inclined plane prevents the swirl flow caused by the rotating rotor blade from impinging the upstream end face and, thereby, suppresses a temperature rise of the split segment at the upstream end face.

Abstract: Il s'agit d'un détecteur de mouvement ou capteur de présence à double technologie, et de la méthode applicable, pour commander un circuit d'éclairage permettant d'activer ou de désactiver des lampes dans une zone surveillée. Ce dispositif fait appel à un capteur de rayons infrarouges, à un capteur à micro-ondes et à un contrôleur. Le capteur de rayons infrarouges produit un signal de détection infrarouge montrant la détection ou la non-détection d'énergie infrarouge, et le capteur à micro-ondes produit un signal de détection à micro-ondes indiquant la détection ou la non-détection de micro-ondes. Le contrôleur produit un signal de commande activant ou désactivant le circuit d'éclairage en réponse à un état du signal de détection de l'énergie infrarouge et à un état du signal de détection de l'énergie à micro-ondes. De manière spécifique, le contrôleur active le circuit d'éclairage pour allumer les lampes dans la zone surveillée, lorsque le signal de détection de l'énergie infrarouge et le signal de détection de l'énergie à micro-ondes indique une présence ou du mouvement dans la zone surveillée. Ce contrôleur maintient alors les lampes à l'état actif, tant que le capteur d'énergie à micro-ondes ou que le capteur de rayons infrarouges détecte une présence ou du mouvement dans la zone surveillée.

Abstract: An automatic steering system is provided with a first position sensor for generating a first position signal and a second position sensor for generating a second position signal. Both position signals are communicated to a controller having a memory. The controller is also supplied signal quality information about the quality of the position signals. The controller evaluates the position signals based on the signal quality information and weights the position signals accordingly to calculate the position of the vehicle and select the vehicle's target path. The target path is selected from several target paths and is the best that corresponds to the position of the vehicle. The controller then generates a steering signal that is communicated to a steering controller for steering the vehicle.
