Title: Systems, methods, and software for classifying documents
Inventor: AL-KOFAHI KHALID
IPC: G06K9/68
Filed: 2002-11-01
Granted: 2011-04-26
Abstract: To reduce cost and improve accuracy, the inventors devised systems, methods, and software to aid classification of text, such as headnotes and other documents, to target classes in a target classification system. For example, one system computes composite scores based on: similarity of input text to text assigned to each of the target classes; similarity of non-target classes assigned to the input text and target classes; probability of a target class given a set of one or more non-target classes assigned to the input text;  and/or probability of the input text given text assigned to the target classes. The exemplary system then evaluates the compposite scores using class-specific decision criteria, such as thresholds, ultimately assigning or recommending assignment of the input text to one or more of the target classes. The exemplary system is particularly suitable for classification systems having thousands of classes.

Abstract: Address translation control (ATC) limits the mappings between virtual and physical addresses in order to implement a memory access policy. Each processor in a mufti-processor system maintains a translation lookaside buffer (TLB) that caches mappings to speed translation of virtual addresses. Each processor also maintains a counter. Each time a processor's TLB is flushed, the processor's counter is incremented. When a link to a page is removed from an address translation map, the counter values for all of the processors are recorded. When that page is accessed by a processor, the recorded counter values are compared with the processor's current counter value to determine whether the processor's TLB has been flushed since the link to the page was removed from the map. An expensive TLB flush operation is delayed until needed, but still occurs early enough to prevent an invalid TLB entry from being used to violate the access policy.

Title: Device for warning of differential pressure during the opening of a pressurized closing device pertaining to an opening in the fuselage of an aeroplane
Inventor: PUSCHMANN CARSTEN
IPC: B64C1/14
Filed: 2003-09-01
Granted: 2010-07-27
Abstract: The invention relates to a device for warning of differential pressure during the opening of a pressurised closing device (1) pertaining to an opening in the fuselage of an aeroplane by means of an opening mechanism (4; 100; 105).  The invention is based on the fact that said device comprises an air channel from the high pressure side (passenger cabin P) to the low pressure side (outside environment A). Said air channel can be closed by a valve (5; 209) which can be controlled by means of a control lever (4; 208) that is actively connected to the door opening mechanism, and said valve (5; 209) produces an acoustic signal in the event of differential pressure when it is opened. One such warning device enables a differential pressure indication to be obtained which is independent of a supply system and is used as a warning signal for a person using an aeroplane door. The differential pressure indication is directly coupled to the action of the user. Furthermore, false alarms are excluded and the warning device is highly reliable.

Granted: 2007-05-22
Abstract: The clamping apparatus comprises a chuck member and a pallet releasably attachable thereto. The chuck member has four centering grooves, arranged offset to each other by 90° around the central Z-axis, while the pallet has four correspondingly located centering pins. In each of the four centering grooves, one of the groove flanks serves for centering the associated centering pin of the pallet, while the other groove flank is constituted by a clamping member. Upon clamping the pallet to the chuck member, the associated clamping member engages a recess provided on the centering pin and pulls the latter one in Z-direction into the centering groove of the chuck member. Simultaneously, the clamping member also presses the centering pin against the other groove flank. Thereby, the pallet is positioned relative to the chuck member in X-, Y- and Z- directions and clamped to the chuck member.

Title: Tri-state integer cycle modulation
Inventor: BOBIER JOSEPH
IPC: H04L/
Filed: 2004-06-24
Granted: 2014-10-28
Abstract: The invention disclosed in this application uses a method of modulation named Tri-State Integer Cycle Modulation (TICM) wherein a carrier signal, comprised of a continuum of sine waves is modulated such that spectrum utilization is minimal. A modulation event is imposed upon the carrier signal by modifying the carrier frequency at precisely the zero crossing point or the zero degree angle. The method of imposing the modulation event is by increasing the frequency of the carrier for one or an integer number of wavelets then lowering the frequency of the carrier for one or the same integer number of wavelets then returning to the carrier frequncy to derive the modulation event. The main carrier frequency is only modulated beginning at the zero degree phase angle and ending at the 360-degree phase angle.

Abstract: The invention relates to a method of lightning-proofing a blade on a wind-energy plant, which blade comprises a blade shell configured essentially as a fibre-reinforced laminate, which laminate comprises electrically conductive fibres, wherein the blade comprises at least one lightning arrester configured for conducting lightning current, including preferably to ground. The method comprises that the electrically conductive fibres are connected to each other, and that at least one metallic receptor is arranged for capturing lightning current at or in proximity of the external face of the blade; and that the receptor and the fibres are connected to the lightning arrester for equalising the difference in potential between the lightning arrester and the electrically conductive fibres. When the electrically conductive fibres are connected to each other, the fibres will cooperate on the conduction of a possible lightning current to prevent the current from running in individual fibres. Simultaneously the metallic receptor will serve as the primary lightning capturing device and reduce the risk of lightning striking the laminate. The receptor being connected to the lightning arrester, the current will predominately be conducted to ground, while the risk of transfer to the laminate is minimised in that a possible difference in potential between fibres and lightning arrester has been equalised.
