Title: Method and apparatus for providing wireless communication system synchronization
Inventor: WALLACE MARK S
IPC: H04W92/00
Filed: 1999-12-03
Granted: 2012-02-14
Abstract: When insufficient traffic is present in the network to maintain synchronization in this manner, other methods must be used. One approach involves making direct measurements of the timing between base stations (602, 604). This is accomplished in one of two ways. The base may interrupt its transmissions on all sectors for a short interval during which it determines the time of arrival of signals from other base stations (602, 604). Given knowledge of the other base station locations, time errors relative to all other base stations (602, 604) may be derived. Alternatively, the base may send a short signal at high power in the mobile transmit band. This time-of-arrival of this signal is measured by the surrounding base stations and the time errors between pairs of base stations are computed. In some cases, a base station (602, 604) may be isolated sufficiently from all other base stations in the network such that direct base-to-base measurement is not viable. In this case, a fixed mobile (606) is placed at a location in the handoff region between the isolated cell and another cell in the network. The fixed mobile (606) either performs measurements of base station pilots on command of the base and reports the timing information, or sends a burst transmission at a specified time and power level to be measured by the base stations.

Abstract: A system for harvester header height and tilt control includes a sensor, such as a crop edge detector, mounted on the harvester for predicting ground contour of an area a substantial distance in front of the header for generally the entire width of the header. An on-board processor calculates the desired header height and tilt for that area in advance of the harvester reaching the area. The early ground contour measurements enable faster and smoother header height adjustments requiring reduced hydraulic power. The predicted contour also facilitates early compensation for effects of abrupt header attitude changes resulting from harvester ground wheels or tracks riding on that contour. The system can be used to maintain header height a preselected distance below the crop heads to reduce harvester throughput.

Title: Variable-speed control system for transmission
Inventor: ONOGI KENKICHI
IPC: F16H55/56
Filed: 2002-05-06
Granted: 2008-06-17
Abstract: In a constant horse-power type continuously variable transmission, a pressing force supply path using for a rotation-speed control, is supplied to one of an input pulley or an output pulley, and an elastic force supply path using for an axial torque control, is supplied to the other. However, since the one pulley is applied only the pressing force as a control element although the torque of the other pulley can be regulated by the elastic force, the frictional force applied to said one pulley cannot be positively regulated, and consequently, whole axial torque controls of an input shaft and an output shaft cannot be achieved sufficiently, and the effect causes the transmission efficiency to deteriorate at both end ranges of a variable speed range. In the present invention, a variable-speed control system for a transmission makes axial torque controls of both the input and output pulleys compensate and hold a low-speed range and/or a high-speed range into a higher transmission efficiency, while cooperating with the semi-elastic force to the one pulley, of which elastic vibration is suppressed by the pressing force thereto to half, and the elastic force to the other pulley. Further, the variable-speed control system is capable of widely expanding an entire transmittable range width to maintain the state of higher transmission efficiency, in combination with a first speed-ratio range and a second speed-ratio range of a first and a second transmission device. By means of using at least the application of the semi-elastic force to the pulley or combination of two individual speed-ratio ranges, a band width of an entire transmittable speed range of the variable transmission is substantially enlarged.

Title: System and method for encoding user information in domain names
Inventor: BELLOVIN STEVEN MICHAEL
IPC: G06F17/30
Filed: 2000-11-30
Granted: 2007-11-06
Abstract: The present invention utilizes a technique based on a domain name system to provide additional information about a user to a service connected to a communication network. User information is stored and encoded into a domain name that is generated and interpreted dynamically. In an embodiment of the present invention, a specialized domain name server is placed at or near a point of presence and has access to private user information on the users who connect through the particular point of presence. Services can utilize a standard domain name query, requesting a domain name given a user's network address, to obtain a name constructed by the specialized server. The name can contain different pieces of information regarding the user encoded cryptographically by different keys to permit only selected disclosure of user information. The present invention provides a way of readily supplying selected user information to a service in a manner that can be authenticated and that is transparent to the user while, at the same time, protecting the privacy of the user.

Abstract: Methods for acidification of soapstock and recovery of acidulated fatty acids, conversion of the acidulated fatty acids to esters, and crystallizing the acidulated fatty acids from the extraction solvent using urea are disclosed. The novel method of adding both a monohydric alcohol to the soapstock to lower viscosity and a strong acid to hydrolyse the soaps prevents the formation of emulsions of soaps and oils, see figure 1. This allows the quantitative recovery of fatty acids and glyceride from the soapstock by removal of the alcohol by evaporation. Alternately, the fatty acids and glyceride may be converted to esters of monohydric alcohols. Heating the fatty acid, glyceride and monohydric alcohol solution produces fatty esters of the extractive alcohol. Chilling the fatty acid, glyceride, and monohydrici alcohol solution allows the selective crystallization of fatty acids. Treating the fatty acid, glyceride and monohydric alcohol solution with urea allows the specific crystallization of fatty acids. The acid water released from this novel process is heavily laden with both organic and inorganic solutes. Processes for recovery of valuable inorganic and organic constituents from the acid water are also described.

Abstract: The method of processing postal objects of large size in order to read automatically a postal address (AD) on each object consists in acquiring a digital image of each object at a certain level of resolution; in detecting in the image one or more zones of interest (ZI) apparently containing a postal address; in performing automatic address recognition on each zone of interest in order to extract a postal address (AD) of the object, and in the event of the automatic address recogition failing, in displaying each zone of interest (ZI) on a screen so that a video-coding operator can read the postal address (AD) of the object. Each zone of interest (ZI) is displayed on the screen on a screen context background (F) that is representative of the object but at a level of resolution that is lower than the level of resolution of the digital image and the zone of interest. In this way, the video-coding operator has an overall view of the detected zones of interest, thus making it easier to read the postal address of the object.
