Title: Partial delegation of complex olap queries with application to zero suppression condition evaluation
Inventor: LEATHERS BURTON
IPC: G06F16/28
Filed: 2000-12-29
Granted: 2007-05-29
Abstract: The present invention introduces a mechanism to partition the processing work required on data from a variety of proprietary OLAP data sources in such a way that as much as possible of the processing can be carried out by the OLAP data source, thereby improving the efficiency of the delegated portion of the operations, and making more effective use of the overall processing power of the computing facilities. By decomposing the required high level expressions into sub-expressions to be applied to data elements some part of the expressions can be evaluated by the OLAP data source. The results of these sub-expressions are combined by the OLAP data engine to produce the same result as the original full expression. 'Rows' and 'columns' of the original cross-tabulation formed from the data are classified as either simple - meaning the expression can be processed at the OLAP data source or complex - meaning such expressions cannot be computed at the OLAP data source. That segment of the cross- tabulation comprising Simple rows and Simple columns can be processed in terms of the high level operation directly by one or more OLAP data sources.

Abstract: It is a serious disaster if a solution can not be found to alleviate the problem of an air accident in which a steel flying machine weighing several tons including its passengers falls to the ground from high in the sky. The present invention provides a solution for this half a century old problem. With this invention, it reduces the large number of fatal losses of lives, transported goods, and air planes over the last half a century. It also eliminates the subconscious fear of such disaster by passengers and pilots alike. The present invention provides three methods of deploying parachutes from the plane body to resolve the above problem. It solves the problem of the parachutes becoming tangled with the large propeller of a helicopter in such circumstances. Thus, it can be readily utilized in an accident. Additionally, speed reduction jets are provided in addition to the parachutes to reduce the falling speed of the helicopter to achieve its safe landing. Inflatable air bags are provided on both sides of its belly and inflatable tubular gaskets are provided around the door joints for sealing these joints such that when falling onto water, the helicopter would float safely to await for rescue. Inflatable air bags are also provided to reduce the impact of the helicopter upon landing on the ground.

Abstract: Cette invention a trait à un capteur pourvu d'une substance active de détection soumise à la substance à détecter et une substance active de référence protégée de la substance à détecter. Le dispositif comporte des thermocouples possédant un ensemble de jonctions à proximité de la substance active de détection ainsi qu'un autre ensemble de jonctions à proximité de la substance active de référence, ces thermocouples étant destinés à la mesure des températures de ces substances respectives. Ces jonctions, qui sont connectées de manière différentielle, permettent de mesurer une différence entre deux températures. Un générateur de chaleur, commun aux deux substances, se trouve à proximité de celles-ci. Il est possible d'appliquer des vagues thermiques à ces substances par le biais du générateur de chaleur, les températures résultantes étant ensuite mesurées. Si des facteurs environnementaux ou certaines substances exercent une influence sur la substance active de détection, la réponse thermique de celle-ci sera différente de celle de la substance active de référence et une indication différentielle du type impulsion sera détectée. Cette indication présentera certaines caractéristiques d'amplitude, de forme et de durée, ce qui permet une identification du type de la substance détectée par le capteur et de sa concentration.

Title: Drop table attachment for sheet feeding machine
Inventor: VEDOY ARILD
IPC: B65H31/38
Filed: 2001-11-02
Granted: 2010-05-25
Abstract: A drop table is used for accumulating a desired number of sheets of items in a bundle and then dropping the bundle onto a conveyor belt. The drop table has a plurality of rods acting as a floor in a collection box. When the drop table receives a signal from a sheet feeder that the number of items desired is in the bundle the rods are withdrawn from beneath the collection box and the bundle drops to a conveyor belt. The rods are then moved back into position for receiving more sheets to form another bundle and the drop table signals the sheet feeding machine to send more sheets to the collection box. The collection box may have a vibrating jogger to align the sheets into a squared bundle on one axis and a tamping foot to align the sheets into a squared bundle on a second axis. The drop table can accumulate sheets in a squared bundle quickly without jamming and release the bundle onto a conveyor below the collection box.

Abstract: A method for controlling drive of an actuator of an active vibration isolation support system allows the waveform of the lift of the actuator to be freely set, while avoiding the generation of heat in the actuator driver and a corresponding increase in the power consumption. Specifically, duty control of the voltage that is applied to the actuator is carried out in each of a large number of consecutive micro time regions such that the waveform of the lift of the actuator can be set freely, and by varying the number of consecutive micro time regions whose duty ratios change with a fixed pattern, the period over which the lift of the actuator changes can be set freely. Moreover, since electrical energy is not wasted as thermal energy in the actuator driver, the problems of heat being generated in the driver and increased power consumption can be avoided.

Title: Gas flow control in gas-assisted esu
Inventor: CRENNER JAMES C
IPC: F17D3/01
Filed: 2000-04-25
Granted: 2006-06-06
Abstract: A gas delivery apparatus used in gas-assisted electrocoagulation temporarily reduces a gas flow rate in a flowpath to an application which applies the fl ow of gas and electrical energy to the tissue during an arc initiation sequence . The reduced gas flow rate enhances the arc initiation capabilities and reduc es the possibilities of embolism. After the arc initiation sequence is complete , the gas flow rate returns to a greater rate used during electrocoagulation. The back pressure in the flowpath and a user requested flow rate are control variables used to reduce the flow rate upon the occurrence of back pressure- related conditions and to increase the flow rate after the dissipation of those back pressure conditions.

Abstract: A kayak paddle (10) with a generally straight shaft (16) that is preferably about 0.7 inches in diameter, the shaft is also conically tapered (24) at either end (18, 20). A left hand grip (12) and a right hand grip (14) are mounted on the shaft, and there is a blade (22) at either end of the shaft. The blades (22) each have a conically tapered socket (42) to accept the tapered ends of the shaft (16). A portion of the socket (42) remains vacant when the shaft (16) is fully inserted, the vacant portion of the socket serv es to trap sufficient air to ensure that the paddle will float. The mechanical connections thus formed prevent the shaft (16) from rotating in the blade sockets (42) and also minimize the amount of stress placed on the adhesive used to fix the shaft in the sockets. The grips (12, 14) ensure that the user's hands can be consistently placed and oriented on the shaft; because o f the small diameter of the shaft, the user's hands can easily encircle the grips, and the user is thereby afforded a high degree of control over the paddle (10). Further, the grips (12, 14) are contoured so as to more ergonomically position the user's hands at natural gripping angles, with respect to the horizontal axis of the shaft; the natural gripping angles ser ve to minimize the stress on the user's wrists, hands and arms.
