摘要:
A hydrostatic drive system includes an anti-slip control unit having a hydraulic pump which supplies a plurality of hydraulic motors of a plurality of axles with pressure medium. Based on a detected slip, a control device switches over between a two-wheel and a multiple-wheel drive and controls the driving torque. Optimal distribution of driving torque and traction between the axles or wheels of the drive system is set in the drive system. A method for anti-slip control of a hydrostatic drive system includes reacting to a slip situation by activating a hydraulic motor for axles or wheels which until then were not driven, or driven only with low driving torque or by increasing the driving torque of wheels which until then did not slip. The capacity of the hydraulic motor of the axles or wheels is raised to enable the activation/increase.

Outputs of an automatic probabilistic event detection system, such as a fact extraction system, a speech-to-text engine or an automatic character recognition system, are matched with comparable results produced manually or by a different system. This comparison allows statistical modeling of the run-time behavior of the event detection system. This model can subsequently be used to give supplemental or replacement data for an output sequence of the system. In particular, the model can effectively calibrate the system for use with data of a particular statistical nature.

An arrangement and method recognizes and classifies preferably hidden objects in object and/or human traffic. Objects relevant to security are recognized, located and tracked through the surroundings thereof in moving object and human traffic isolated in real time. Use is made of a combination of a field generator, the field of which is modified by at least one corresponding object within the scanned space, first sensors which repeatedly record the changes in the field and provide corresponding signals, second sensors which record defined surroundings of the object in real-time with relation to the first sensors and provide corresponding signals and analytical means which correlate and collate the signals from the sensors with each other and which give from the same the shape, spatial position and/or spatial orientation of the object.

The invention relates to a drive system and to a method for monitoring a hydrostatic drive (1). The hydrostatic drive (1) has at least one hydrostatic piston engine (2) on which a control unit (6, 6′), which controls the hydrostatic piston engine (2, 2′), is arranged, wherein the control unit (6, 6′) is connected to a central control device (13), which controls the drive system (1), via a first interface (14). Control signals for controlling the drive system (1) can be transmitted using the first interface (14). The central control device (13) is additionally connected to the control unit (6) via a second interface (26, 26′), and a switch-off signal can be transmitted from the control unit (6, 6′) to the central control device (13) and/or from the central control device (13) to the control unit (6, 6′) using the second interface (26, 26′).

A method for automatically providing a plurality of additional database query terms to a user is provided. The method comprises receiving a query term from a user, receiving a plurality of characters from the user in addition to the query term, and selecting a set of records from a database based on the query term, wherein the database comprises records, and the records comprise text translated from audio. The method also determines a plurality of additional query terms based on the plurality of characters, and, for at least one of the plurality of additional query terms, processes at least a portion of the set of records to determine a relevance of the additional query term. Finally, the method includes displaying at least one of the plurality of additional query terms to the user for selection, the display based on the relevance of the at least one of the plurality of additional query terms.

Conductive apparatus having minimized AC resistance. The conductive apparatus comprises a planar rectangular conductor having top and bottom surfaces, and opposed end surfaces that are smaller in dimension than the top and bottom surfaces. Magnetic material is disposed adjacent to each of the end surfaces of the rectangular conductor that is formed in a "C" shape to provide end caps that are symmetrical and enclose the end surfaces and portions of the top and bottom surfaces to overlap the conductor in its corners. A method of fabricating the conductive apparatus is also disclosed.

Frequency regulating apparatus comprising a high power, voltage variable dielectric varactor or capacitor (or ferroelectric voltage variable dielectric capacitor) for use as a control element in the regulation circuit that actively tunes a resonant network to modulate power delivered to a load. The voltage variable dielectric capacitor comprises a substrate having a bottom electrode 33 formed thereon. A dielectric material is disposed on the substrate is a crystallized ceramic material that preferably comprises a barium, strontium, and titanium mixture. A top electrode is disposed on top of the crystallized ceramic material. Methods of fabricating the voltage variable dielectric varactor (capacitor) are also disclosed.
摘要:
A method for user input includes capturing a sequence of positions of at least a part of a body, including a hand, of a user of a computerized system, independently of any object held by or attached to the hand, while the hand delineates textual characters by moving freely in a 3D space. The positions are processed to extract a trajectory of motion of the hand. Features of the trajectory are analyzed in order to identify the characters delineated by the hand.
摘要:
A computer system coupled to a database is configured to receive a database query, and evaluate a set of records from a database based on the database query. The database comprises a plurality of records, and each record comprises text translated from audio. The system then determines a plurality of measurement terms based on the database query, and processes at least a portion of the text of at least one record of the database to determine a quality of the database query based on the occurrences of the measurement terms within the portion of text, and performs an action based on the quality of the database query.
