Title: A system and a method relating to packet data communication
Inventor: HALL GOERAN
IPC: H04L12/56
Filed: 1999-03-05
Abstract: The present invention relates to a cellular communication system supporting packet data communication including a number of switching arrangements for switching speech and/or circuit switched data. It also comprises a number of packet data nodes (1), each controlling/serving the packet data communication in a number of packet paging areas (10). In each cell a number of packet data communication channel resources are used for packet data communication and each packet data node comprises mobile station information handling means keeping information about mobile stations registered in the cells covered by the packet data node (1). Cell information handling means are further provided keeping information about packet data communication channel resources in the cells covered by the packet data node (1). Means are provided for calculating which packet data communication channels are to be used for mobile stations after updating of a cell. Furthermore means are provided for keeping information about which cells have been updated and when a cell is updated, paging of a mobile station (MS1) in a stand-by state is performed by sending a number of first paging messages from the packet data node using the calculated packet data communication channel resources in all cells (C1-C12) within the packet paging area (10) in which the mobile station (MS1) is registered. If the mobile station is not found, a second paging message is sent out to all cells which have been updated, advantageously on all packet data communication channel resources (  S   UPCH<SB>i,k,m,l,s</SB>) of such cells (C2, C3, C4, C5, C12).

Title: Correcting high order field inhomogeneities
Inventor: NAUERTH ARNO
IPC: G01R33/565
Filed: 2000-11-16
Abstract: A method of correcting field inhomogeneities of higher order in a magnetic resonance apparatus. After an excitation pulse and action of a phase gradient in a predetermined direction p, a data point is recorded after two predetermined times t<SB>d1</SB> and t<SB>d2</SB>. This is repeated for systematically modified strengths of the phase gradient and constant t<SB>d1</SB> and t<SB>d2</SB>, and two sets of signal dependences in the p direction are obtained. The two phase dependences of the two Fourier transformed data sets in the p direction are subtracted. The profile of the difference phase in the p direction corresponds to a field error profile. The method is repeated for several p directions, and coefficients of higher order of a series expansion of the field inhomogeneities in spherical harmonic functions are obtained.

Title: Quantity gauging system
Inventor: ATKINSON HARRY
IPC: G01F23/26
Filed: 2001-01-08
Abstract: An aircraft fuel quantity gauging system has a number of probes 10 and 11 within a tank 1 to measure the height of fuel 2 at different locations. Each probe 10 and 11 includes a still well 12 and an ultrasonic transducer 15 and 14 mounted at the top and bottom of the still well. The lower transducer 14 transmits pulses of acoustic energy upwardly through the fuel 2 to its surface 3 and measures the time of travel back of the reflected pulse back to the transducer. This is used to derive a first, bottom-up measure of fuel height. Similarly, the upper transducer 15 transmits pulses down through air 4 to the fuel surface 3 to derive a second, top-down measurement. These are compared to check for correct operation of the probes.
Patent GB-2371191-A (GB)
Title: Detecting double-talk and path changes in echo cancellers
Inventor: SEIBERT MICHAEL
IPC: H04M1/00
Filed: 2001-01-11
Abstract: To detect double-talk and path changes in an echo canceller, a correlation-based matrix of signals is generated. Analysis of the matrix enables identification of double-talk and path changes. The matrix may be generated using zero-lag auto- and cross-correlations. Double-talk and path changes are inferred when a determinant of the matrix passes a threshold. Alternatively, eigendecompositions or single value decompositions of the matrix may be used. The elements of the matrix may be generated in the time or in the frequency domain. The canceller may employ an adaptive filter implementing a normalised-LMS algorithm.

Title: Password storage apparatus and method
Inventor: KEETCH ALLEN JOHN
IPC: G07F7/10
Filed: 2001-02-02
Abstract: A memory device 30 allows a person to remember only a single code and use that code to retrieve the identifying code or password required to access a secure facility. The memory device 30 is nearly the size and shape of a credit card and has a display 32, keypad 34, and housing 44, which may be tamper-proof, having a writing portion 46 on the rear. A user initially uses the keypad 34 to enter both a memory access code and a separate identifying code associated with each secure site or equipment. Subsequently, when the user desires to access a selected site or equipment (s)he can enter the access code and read, from the display, the required identifying code. A mnemonic descriptor can be written on a designated blank writing portion 46 on the housing, for each stored code. A brief advertising message can also be stored in the device memory and displayed each time the device is turned on. In a preferred embodiment, all the stored identifying codes are erased after a predetermined number of sequential inputs of the incorrect access code.

Title: Bubble evaporation of solvent fuel within a container
Inventor: CHUANG TA-MING
IPC: F23K5/22
Filed: 2002-10-11
Abstract: An air inlet line 3 extends to the bottom of a solvent fuel container 1, permitting the bubble evaporation of the solvent fuel by air drawn into the container 1 by a blower 2.

Title: Improved method for estimating TDOA and FDOA in a wireless location system
Inventor: ANDERSON ROBERT J
IPC: G01S5/06
Filed: 2002-01-10
Abstract: A method, used in locating a mobile transmitter, includes providing a set of cross-correlation values, wherein each cross-correlation value is associated with a corresponding TDOA and/or FDOA estimae and is produced by cross-correlating a reference signal with a cooperating signal (fig. 5).

The method further includes determining a most likely range of TDOA and/or FDOA estimates, and then identifying an optimal cross-correlation value within a subset of cross-correlation values (fig. 10) corresponding to the most likely range of TDOA and/or FDOA estimates. The TDOA and/or FDOA value corresponding to the optimal cross-correlation value is then employed in calculating the location of the mobile transmitter.
