In assisted satellite positioning systems, acquisition of navigation signals emitted by the satellites is facilitated as assistance data are provided to the mobile station. At a server station, a request for assistance data issued by the mobile station is received, and the server station transmits ephemeris data as part of the assistance data to the mobile station in response to its request. Upon receiving the request for assistance data issued by the mobile station, the server station decides whether the mobile station could achieve a specified position fix accuracy if the mobile station was provided with the broadcast ephemeris data. In the positive, the server station transmits the broadcast ephemeris data to the mobile station. In the negative, the server station transmits, instead of broadcast ephemeris data, long-term ephemeris data to the mobile station as part of the assistance data requested.

A radiating portion of the antenna feed layer comprising a conductive patch antenna element is placed in between the enclosure and the cover. This patch antenna element design is inherently broader band than that of conventional cavity-backed slot-radiating antennas, which are constrained in bandwidth by the need to keep the cavity formed in the enclosure small, so that the column elements may be arranged in an array at substantially half-wavelength spacing. The new design suffers less compromise in terms of bandwidth in achieving the same size constraint.

20090303213 | SIGNAL LINE DRIVING CIRCUIT AND LIGHT EMITTING DEVICE - Variations occur in the characteristics of transistors. The present invention is a signal-line drive circuit comprising first and second current source circuits corresponding to respective plurality of signal lines, a shift register, and n (n is a natural number of one or more) video-signal constant current source s, wherein each of the first and second current source circuits has a capacitance means and a supply means. The capacitance means held in one of the first and second source circuits converts a current including a current supplied from each of the n video-signal constant current source s to voltage in response to a sampling pulse supplied from the shift register and a latch pulse supplied from the exterior; and the supply means held in the other supplies a current responsive to the converted voltage. The values of the currents supplied from the n video-signal constant current source s are set to a proportion of 2 | 2009-12-10 |
