G06F16500

US Classification:

706 4, 701 19, 701 20

Abstract:

An automatic train handling controller. In one embodiment, there is disclosed a system and method for tracking a velocity profile in a rail-based transportation system. A fuzzy logic controller is used to ensure that a train simulator complies to the velocity profile over a specified track profile while providing a smooth ride. A safety constraint enforcer is used to minimize sudden slack movements by ensuring that the control action provided by the fuzzy logic controller is kept in compliance with a set of predetermined safety constraints. In a second embodiment, there is an automatic train handling controller that smoothly manages the slack of the couplers while keeping the train within prescribed speed limits over a varying terrain.

Abstract:

In a distributed computer system, such as the World Wide Web portion of the Internet, a first computer requests to a second computer remote from the first computer to search information of at least one entity. The first computer indicates to a search agent associated with the second computer at least one search criterion for the search. The search agent accesses at least one database remote from the first and second computers that stores information of a number of entities, including the at least one entity. The at least one entity is less than all of the plurality of entities with information in the at least one database. A search based on the at least one search criterion is performed by the search agent only on the portion of the database related to the at least one entity. In one embodiment, the first computer is associated with a buyer, the second computer allows access to a Web site of a merchant offering goods and/or services for sale, and the portion of the database relevant to the merchant stores an electronic catalog of the goods and/or services of the merchant.

International Classification:

G01C 308
G01C 500

US Classification:

356 402

Abstract:

A calibration device for a laser ranging system includes an interferometer assembly and a beam path magnifier assembly which is optically coupled to the interferometer assembly to receive a calibration beam therefrom and to the laser ranging system to receive a laser ranging beam therefrom. The calibration beam and the laser ranging beam enter the beam path magnifier assembly such that they pass along equidistant paths and so that the calibration beam is detected by the interferometer assembly to provide a precise measurement of the distance the calibration beam traveled and the laser ranging beam is detected by the laser ranging system to provide a measurement of the distance traveled by the laser ranging beam along the calibration optical path. Comparison of the two readings provides calibration data for the laser ranging system. The beam path multiplier assembly includes means for varying a folded calibration optical path length to provide a range of calibration beam path lengths.

General Electric Company - Schenectady NY

International Classification:

B23K 2600

US Classification:

2191216

Abstract:

Apparatus for laser processing, such as drilling of a workpiece, optionally has an optical fiber and output coupler for applying laser light to machine a workpiece and cause it to vibrate. An acoustic sensor is mounted on the workpiece, and a determining means, such as a computer, determines when the vibrations change, such as when they cease. The information can be used to change the laser pulse power and duration and the relative distance of the laser focal plane on the workpiece. A method of laser processing a workpiece causes vibrations in the workpiece by applying laser light to it, monitors the vibrations, and determines when they change.

International Classification:

G01B 1124

US Classification:

356376

Abstract:

A precision non-contact measurement system for determining the diameter of a curved workpiece includes a non-contact range sensor that is disposed along an orthogonal axial path with respect to the axis of rotation of a precision rotary device on which the workpiece to be measured is mounted so as to determine a radius value of the workpiece disposed along the orthogonal path, and a workpiece measurement processor coupled to receive signals from the range sensor and the precision rotary device so as to correlate a plurality of rotational positions of the workpiece with corresponding respective radius values sensed by the range sensor so as to determine the shape and an integrated diameter of the workpiece, that is a diameter measurement determined from rotation of the workpiece through a selected arc of rotation, typically 360. degree. The non-contact range sensors typically comprise optical sensors such as laser range sensors and light-emitting-diode (LED) type sensors. The precision rotary device commonly comprises a platen on which the workpiece is disposed and a signal generator for generating a signal corresponding to the rotation position of the workpiece throughout 360. degree.
