Title: Path search circuit for simultaneously performing antenna directivity control and path search
Inventor: SATO TOSHIFUMI
IPC: H04B1/707
Filed: 2000-07-12
Abstract: A path search circuit simultaneously performs antenna directivity control and a path search. A weighting controller controls weighting coefficients to establish an antenna directivity in a plurality of directions in which a party to communicate with is possibly present, when a communication session starts. A weighted-mean-value processor calculates delay profiles for the respective antenna directivities. A correlation peak detector detects a peak from the calculated delay profiles for thereby carrying out general antenna directivity control and a path search. At the time of starting the communication session when the direction of a mobile terminal is unknown, a path search can be conducted using a signal with a Eb/Io increased by an antenna gain for increased path search accuracy.

Title: Manufacturing apparatus and manufacturing method of solid polymer film with catalyst deposited thereon
Inventor: TANAKA KATSUHISA
IPC: H01M8/02
Filed: 2001-01-11
Abstract: An apparatus and method for manufacturing a solid polymer film with a catalyst sufficiently deposited thereon preheats a solid polymer film and then hot presses this solid polymer film together with a catalyst carrier film. Hot pressing the solid polymer film while it is soft from preheating increases the bond strength between the solid polymer film and the catalyst such that separation of the catalyst from the solid polymer film during film separation can be prevented. Moreover, keeping the catalyst carrier film cool prior to hot pressing and making the temperature on the catalyst carrier film side slightly lower that than on the solid polymer film side during hot pressing inhibits an increase in binding strength between the film and the catalyst, and thereby improves separation of the film.

Patent CA-2334141-A1 (CA)
Title: A method and apparatus for extrusion of expanding water holding products such as foodstuff particles or feeding stuff pellets
Inventor: FLARUP-KNUDSEN ANDERS
IPC: A23P1/14
Filed: 1999-05-27
Abstract: In the extrusion of feed-stuff pellets and relevant consumer products, the extruded products are subject to expansion as a result of the boiling of the ir water content when the products, after being exposed to high extrusion pressure and a correspondingly high temperature, are discharged to the atmosphere through the extrusion nozzles. Such an expansion is directly aime d at, but it is desirable to be able to control it, which is difficult by adjustment of the ordinary process parameters. With the invention it has bee n found that the expansion which arises can be controlled in a highly constant  manner, i.e. by carrying out the extrusion into a closed chamber in which an  over-pressure of a few bar is established in relation to the atmospheric pressure, and which can be regulated. The extrusion products can be continuously discharged from this chamber, or they can be discharged intermittently in portions. The over-pressure moderates the momentary development of steam in the extruded product, and the product is given time to stabilise before being discharged to atmospheric pressure, so that the subsequent further development of steam influences the structure of the product only to a minor degree.

Title: Location-based vehicle risk assessment system
Inventor: JONES STEVEN PAUL
IPC: G06Q40/08
Filed: 2001-02-15
Abstract: An apparatus, program product and method track the location of a vehicle during at least a portion of a period of the time associated with an economic transaction so that risks associated with the actual usage of the vehicle can be accommodated in the costs for the transaction. In particular, a determination is made during a time period associated with an economic transaction as to whether the vehicle is located at a location having an increased level of risk. Costs for the economic transaction are then adjusted based at least in part on the presence of the vehicle in a location with an increased level of risk. In one exemplary environment, car rental rates are adjusted based upon the actual usage of a rented vehicle. In another exemplary environment, insurance premiums are adjusted based upon the actual usage of an insured vehicle. In either event, usage that results in a vehicle being located in areas of comparatively higher risk can be accounted for in additional transactional costs, resulting in improved allocation of risk and minimization of economic inefficiencies.

Title: Mechanism for generating wave motion
Inventor: SARINGER JOHN H
IPC: A61G7/057
Filed: 1999-07-23
Abstract: The present invention provides a wave generating apparatus for generating waves in for example beds, chairs and the like. In one aspect the device includes a motor driven crankshaft to which are attached several longitudinal beams. The beams mounted on the crankshafts are offset with respect to each other in such a way as to produce a phase shift between the beams. Each beam is provided with several links pivotally attached at one end to each beam and the links are spaced apart along each beam by a distance equal to the desired wavelength of the wave being produced. The other ends of each link is attached to a flexible membrane which forms a support surface of the bed or chair. The links from the different beams are interleaved at equal phase intervals so as to produce a traveling wave in the flexible membrane so that a complete wave passes during each full rotation of the crankshaft assembly. In another embodiment the motor is replaced by a generator and the mechanical movement of the flexible membrane driven by a fluid for example is converted into other forms of mechanical or electrical power.
