Title: Fast approximate string matching algorithms for multiple errors spelling correction
Inventor: DU MIN-WEN
IPC: G06K9/62
Filed: 1991-12-30
Abstract: A data string processing system uses fast algorithms for approximate string matching in a dictionary (23). Multiple spelling errors of insert, delete, change and transpose operations on character strings are considered in the disclosed fault model. S-trace, the fault model is used in formulating the algorithms and, a four-step reduction procedure improves the efficiency of an approximate string matching algorithm. These approaches to spelling correction, (i.e., using the upper bound, the string length partition criterion and the cut-off criterion) represent three improvements from the basic exhaustive comparison approach. Each can be naturally incorporated into the next step. In the fourth-step, a hashing scheme avoids comparing the given string with words at large distances when searching in the neighborhood of a small distance. An algorithm that is sub-linear to the number of words in dictionary (23) results. An application of the algorithms to a library information system uses original text files (21), information description files (22) and a negative dictionary (23) stored on disks (12).

Title: Method and device for ascertaining the dynamic mass and the mean frictional force of a lift door
Inventor: GERSTENKORN BERNHARD
IPC: E05F15/632
Filed: 1992-12-18
Abstract: By this method, the masses and the frictional forces of all movably interconnected installation parts are referred to the door leaf (2) in a sliding door system (1) and ascertained numerically with the aid of the closing weight (G). For this purpose, the door leaf (2) is subjected to an opening learning travel (öL) and a closing learning travel (SL) and in that case guided without drive over a respective test section TS1 and TS2 and a first energy balance (EB1) and a second energy balance (EB2) respectively are set up from then measured kinematic parameters (v1, v2, s1) and (v3, v4, s2). The energy balances (EB1, EB2) contain the potential energy (Ep) of the closing weight (G) with positive or negative sign and in combination result in special formulae for the numerical values of the dynamic mass (md) and the mean frictional force (Fr*) of the sliding door system (1). The microprocessor (3.1) and the incremental transmitter (3.2) of the door drive (3) serve for the measuring, storing and processing of the kinematic parameters as well as for the computation of the numerical values of the dynamic mass (md) and the mean frictional force (Fr*). The method is generally applicable to mass systems and their physical characteristic values and is suitable particularly for the ascertaining of the closing speed (vsmax), which is the maximum permissible for reasons of safety technique, of sliding and pivoting doors.

Abstract: OBJECT LOCATOR SYSTEM                  Abstract of the Disclosure An object locating system, especially for use in locating a gaming ball in the game of football, utilizes a series of three sensors positioned on one side of a football playing field and a calibration source positioned on the other side.  The calibration source emits an ultrasonic signal which is received by the sensors in order to provide a calibration signal.  A ball marking unit is positionable on the field at a location of the ball and emits an ultransonic signal which is received by the sensors and an RF signal which is received by the calibration source in order to turn the calibration source off.  The sensors provide signals in which a processing unit calculates time delays by a time acquisition process in order to determine the position of the ball.  In an alternate embodiment, the ball marking unit emits only an RF signal which is received by the sensors.  The sensors again provide signals which are analyzed by the processing unit to determine delay between receipt of the signals at the sensors.  Additionally, an automatic ball marking unit on a track drive can be controlled by the processing unit to automatically provide a visual representation of the ball's location.

Title: Intermediate transfer medium and process for producing image-recorded article making use of the same
Inventor: WATANABE NIRO
IPC: B41M5/52
Filed: 1993-09-01
Abstract: An intermediate transfer medium comprises a heat-resistant base sheet and provided thereon a release layer and an image-receiving adhesive layer, on which an image pattern is formed by a sublimation transfer means in accordance with image data, said image-receiving adhesive layer, on which said image pattern has been formed, being transferred to a transfer substrate together with said release layer to produce an image-recorded article, wherein said image-receiving adhesive layer is comprised of a thermoplastic resin having a glass transition point of 50°C or above and a filler added to the thermoplastic resin and selected from the group consisting of an inorganic filler having a melting point of 200°C or above and an organic filler having a softening point or decomposition point of 200°C or above.     Because of the inorganic or organic filler contained in the image-receiving adhesive layer, there is no possibility that the image-receiving adhesive layer is transferred to the transfer ribbon side in the step of forming the image pattern even when the thermoplastic resin constituting the image-receiving adhesive layer has a low heat-melting temperature. Also, since the additive such as silicon need not be used, the layer can have an improved adhesion to the transfer substrate. In addition, since the thermoplastic resin constituting the image-receiving adhesive layer has a glass transition point of 50°C or above, the image may by no means undergo any change due to heat.
