Title: Improved communication switch
Inventor: STANAWAY JOHN JOSEPH JR
IPC: H04L12/56
Filed: 1998-01-30
Granted: 2002-11-19
Abstract: An enhanced communication network switch utilizes a Time Slot Interchange facility to decompose and compose composite ATM cells that each comprise a 5 byte header and a 48 byte payload. The payload comprises data from a temporarily defined set of call connections of a virtual 48 channel transmission facility; and the switch comprises a Cell Header Decoder comprising a plurality of records which direct operation of the TSI to decompose corresponding received composite ATM cells. Atthe time that a cell is committed to call connection service, the switch seizes and initializes an idle record in the Cell Header Decoder. For the purpose of composing a composite ATM cell for transmission to an ATM line, Cell Header and payload data are read from memory locations assigned to call connections served by the cell during the time slots currently assigned to the cell.

Title: Radio apparatus
Inventor: MAEDA TADAHIKO
IPC: H03L7/08
Filed: 1998-03-12
Granted: 2002-09-17
Abstract: In a radio apparatus, the band of a loop filter of a synthesizer in a blank channel searching state is narrower than the band in a communicating state.  In addition, a radio wave environment is measured.  A characteristic necessary for the radio apparatus is determined corresponding to the measured radio wave environment.  The power is controlled corresponding to the performance of the radio apparatus.  Thus, the power consumption is decreased.  In addition, the efficiency of the output power is improved.  In the radio apparatus, the current consumption of a power amplifier PA is measured.  A matching circuit (LNA or MIX) of the antenna is adjusted with the measured result so as to decrease an antenna loss.  In the radio apparatus, a DC offset is removed from the transmitted power and the reflected wave.  When the DC offset is removed using an AC coupling capacitor, the deterioration of the frequency characteristic of the receiving portion is compensated with a capacitor in a digital signal process.  In the radio apparatus, a transmission power detecting portion is structured as an IC chip.  The transmission power detecting portion detects the transmission power corresponding to leakage currents in the power supply of the IC chip and the ground.  Thus, when the power is detected, a power loss is suppressed.  Consequently, the power consumption of the radio apparatus can be decreased.

Abstract: The present invention provides a system and process for correlating points o n a spatial body to corresponding points on a database body formed from pre-acquired images of the spatial body. The system and process involve matching the spatial points wit h the corresponding database points using relative positional information between the spatial points and the database points. Symmetric false matches are detected and discarded by fitting the spatial points and database points to a first and second closed body, respectively, and comparing the orientation of the spatial points and the database points projected onto the closed bodies. In a preferred embodiment, the orientations of the spatial points and database points are compared by calculating with respect to a matched spatial point, the longitudinal coordinates of the spatial points neighbouring the matched spatial point and calculating, with respect to the matched database point, the longitudinal coordinates of the database points neighbouring the matched database point, and comparing the difference in longitude between the points. If the difference in longitude of the spatial points corresponds to the difference in longitude of the database points, the match of the matched spatial point to the matched database point will be validated. Otherwise, the match will be considered a symmetric false match and discarded. Once at least three spatial points have been matched to corresponding database points, and the matches have been confirmed not to be false matches , a registration procedure is performed registering the spatial body to the database body by calculating a transformation mapping using the three matched pairs.
