Abstract: A system for locating a device in a wireless network that caches a known location and estimates a location at a given time based on a speed at which the device is moving. The system initially determines plural locations and determines the speed from location. The speed and location information is stored in a cache. The system also includes a mechanism to query the cached. The system extrapolates an estimated location of the device based on the time of the query and speed of the device. Route information may be factored into the determination to account for traffic, transit or travel itinerary.

Abstract: An arrangement where a transmitter has a plurality of transmitting antennas that concurrently transmit the same symbol, and where the signal delivered to each transmitting antenna is weighted by a factor that is related to the channel transmission coefficients found between the transmitting antenna and receiving antennas. In the case of a plurality of transmit antennas and one receive antenna, where the channel coefficient between the receive antenna and a transmit antenna i is hi, the weighting factor is hi* divided by a normalizing factor, ?, which is ( ? k = 1 K ? ? h k ? 2 ) 1 / 2 , where K is the number of transmitting antennas. When more than one receiving antenna is employed, the weighting factor is 1 a ? ( gH ) H , where g=[g1 . . . gL], H is a matrix of channel coefficients, and ? is a normalizing factor ( ? p = 1 L ? ? q = 1 L ? ? ? k = 1 K ? h pk ? h qk * ? ) 1 / 2 .

Abstract: A tree-structured index to multidimensional data is created using occurring patterns and clusters within the data which permit efficient search and retrieval strategies in a database of DNA profiles. A search engine utilizes hierarchical decomposition of the database by identifying clusters of similar DNA profiles and maps to parallel computer architecture, allowing scale up past previously feasible limits. Key benefits of the new method are logarithmic scale up and parallelization. These benefits are achieved by identification and utilization of occurring patterns and clusters within stored data. The patterns and clusters enable the stored data to be partitioned into subsets of roughly equal size. The method can be applied recursively, resulting in a database tree that is balanced, meaning that all paths or branches through the tree have roughly the same length. The method achieves high performance by exploiting the natural structure of the data in a manner that maintains balanced trees.

Abstract: A tile, made for example of leather, having a first face, a second face, side edges and a plurality of holes that bring into communication first face with second face. In a lining made with such tiles like this, the holes lead the air from below to above the tiles. To improve further the air flow through the tile, on the second face a plurality of grooves are made that extend from a central zone up to the side edges of the tile. This way, an air path is formed between the lining and the floor leading the air to holes and then into the room at the side of first face. A favorable exchange rate through a floor lining made with them is obtained, combined with a heat exchanger embedded in the floor.

Abstract: A signage system comprising a prism-shaped tri-panel louver having a slot at each corner into which can be slid a clip. The clip is generally V-shaped with a pair of opposing sides joined at one end to form an apex. At the apex end is a pair of opposing fingers which are generally parallel to the clip sides. The fingers form a slot on each side. The clip is slid and retained by a friction fit within the slot such that when three clips are installed the fingers and slots formed therein can hold the sign graphics strip. The clip can flex somewhat to allow for insertion in a slot in the louver.

Abstract: A method for accessing a reverse channel for communication from a remote unit to a base station is disclosed. The method includes waiting a random period of time in response to determining that the reverse channel is available at a first time. The method also includes monitoring a forward channel after expiration of the random period of time to determine whether the reverse channel is available at a second time. The method further includes transmitting a first portion of data on the reverse channel in response to determining that the reverse channel is available at the second time.

Abstract: An apparatus for billiards practice, comprising a housing; an emitter connectively disposed to the housing; a pair of detectors equally spaced about the emitter; a controller having logic controlling the emitter; at least one indicator in communication with the logic; the logic receiving at least one signal from the detectors via the emitter projecting the signal onto the surface of the billiards ball; the logic resolving the position of the billiards ball with respect to the emitter in concert with the detectors; and a response to the logic resolved position of the billiards ball via the indicator. The player's instant feedback is implemented via a controller disposed within the billiards practice device. The controller has means to emit infrared signals and capture the return reflected infrared signal from the cue ball. The returned infrared signals are interpreted and processed via the controller.

Abstract: A drinking trough having a drinking valve assigned to a water-supply line, the drinking valve having a valve pin that moves in order to discharge water; a water-collecting bowl assigned to the respective drinking valve; an actuating means or elongated actuating end of the valve pin extending from the valve pin to a water-accommodating hollow of the water-collecting bowl, the actuating means being movable between an actuated position to an unactuated position; and a starter body assigned to the respective water-collecting bowl, in which the starter body actuates the actuating means by moving the actuating means to the actuated position when water in the water-collecting bowl reaches a certain lower level, whereby the moving of the actuating means to the actuated position actuates the valve pin so as to allow water to flow from the drinking valve into the water-collecting bowl, and when the water in the water-collecting bowl reaches a certain higher level, the actuating means moves to the unactuated position, w

Abstract: A golf ball position marking assembly that includes a marker removably secured to a decorative or functional accessory item such as a ring, pendant, clip, belt, key ring, bracelet, buckle, divot tool, or the like.

Abstract: A method of reducing mercury levels in a mercury contaminated material using microwave energy. The method comprises the steps of (a) placing the mercury contaminated material in a microwave reactor; (b) providing a stream of gas in the microwave reactor, the stream causing agitation of the mercury contaminated material; and (c) exposing the mercury contaminated material to microwave radiation so as to raise the temperature to at least 357° C., producing a vapour phase which contains mercury and a treated material. The method also allows for a simultaneous reduction of mercury and carbon levels in the material to be treated as well as the use of a carbon-free material in the reactor.

Abstract: A method for determining atomic isotope masses in mass spectrometry, atomic isotope ratios being determined from molecular isotope ratios measured by means of an isotope mass spectrometer—ion correction, the determination of the atomic ratios being carried out by setting up and solving a system of equations which describes relationships between the atomic and the molecular ratios, and the system of equations having to have at least as many independent equations as there are atomic ratios. The entire system of equations is linearized by means of suitable numerical methods in a first step, in particular by means of a Taylor expansion or similar method, and in which the linearized system of equations is subsequently solved as a whole without transforming the individual equations.
