A multifunction printed antenna for wireless and telematic applications. In one embodiment, GPS and satellite radio patch antenna elements are printed on one side of a printed circuit board and AMPS, PCS, GSM and terrestrial radio slot antenna elements are etched in a ground plane on an opposite side of the same printed circuit board. In an alternate embodiment, the GPS and satellite radio patch antenna elements are elements mounted on one printed circuit board and the AMPS, GSM, PCS and terrestrial radio slot antenna elements are etched in a ground plane on another printed circuit board rigidly secured orthogonal to the GPS and satellite printed circuit board. The AMPS, GSM and PCS circuit board can be curved to reduce the nulls at the edges of the circuit board. Further, the edge of the AMPS, GSM and PCS circuit board that contacts the GPS and satellite radio circuit board can have a saw-tooth pattern so that edge currents are reduced.

This disclosure describes a method of payment for parking of a vehicle including determining the location of the vehicle with a wireless communication device. Determining the location includes using a satellite radio navigation system such as GPS with the facility for user provided corrections and avoiding the use of zone IDs. The method also includes automatically extending an initiated parking session with subsequent prepaid time durations until certain predetermined conditions are met. The method includes automatically determining the end of an initiated parking session based on detecting movement of the vehicle away from a parking spot provided the Handset containing the parking payment App has sensed a Bluetooth tag in the vehicle or paired with the built-in Bluetooth system of the vehicle. The method also includes targeted parking enforcement where parked vehicles are identified wirelessly by short range radio beacons emitted by tags placed in/on the vehicles and their session status checked with information downloaded from a parking application server.

A novel and useful apparatus for and method of securely downloading and installing a patch program in a processing device. Each processing device is assigned a unique key embedded therein during manufacture and has knowledge of a shared key. The program patch is encrypted using the shared key and transmitted over a communication link, such as a satellite radio link, to each device. The patch is decrypted using the shared key and re-encrypted using the unique key known only to the device itself. The re-encrypted patch program is stored in nonvolatile memory and upon reset of the device, the encrypted patch contents are read out of the nonvolatile memory, decrypted using the unique key and loaded into patch memory for execution by the processing device.

A content channel is periodically or permanently allocated for use as an “update channel” or “firmware-image download” channel. Any firmware images downloaded to receivers in the system are thoroughly tested prior to being distributed among the receivers. Header information is included in the firmware image when it is transmitted to the receivers, and the firmware image is not accepted for use by the receivers until it is verified on the receiver side. Further, rather than overwriting the existing firmware, the new validated firmware updates are stored separately on the receivers and are utilized when the receiver is rebooted during power-up or by the host controller. If, during this reboot process, an error occurs in the new firmware image, the receiver is configured to revert back to the original firmware image so that it will remain operational, albeit without the updated firmware features.

A portable, data storage device, player, playback device, data streaming device, audio player, video player, audio and video player, satellite radio device, cellular phone (with an integrated audio and/or video player), PDA (personal digital assistant), PMP (portable media player), gaming device, handheld and/or mobile device, each embedded with inherent audio and/or video playing/playback capabilities, attached to a docking station or cradle via a single or plural audio/video connectors, wirelessly transmitting audio and/or video and/or control data via infrared optical signals to a set of remote wireless receiving device/s, speaker/s and/or video reproduction device/s.

Digital data objects containing video-based advertisement information are broadcast via satellite and received by one or more integrated receiver decoders (IRDs). Each IRD selectively discards or caches advertisement objects (AOs) in a local memory. AOs that are incompatible with the sophistication level of the IRD and/or user preferences/characteristics are discarded without being cached and AOs that have a lower priority than currently cached AOs are discarded. The IRD arranges cached AOs into ordered lists to schedule them for display and each ordered list corresponds to a unique display position within a program guide. When the user initiates a program guide session, the IRD cyclically displays the AOs in the program guide according to the ordered lists.

A system and method for the efficient use of satellite radio modems and satellite bandwidth is disclosed. In the system and method, a satellite radio modem is used for PRACH requests, each PRACH request occupying 31.25 kHz in a packet data transfer channel. The packet data transfer channels can be either 125.0 kHz or 156.25 kHz. Therefore, four PRACH requests can be transmitted in any one packet data transfer channel. The packet data transfer channels are broken into eight time slots, and one time slot in each channel (either the odd frame or even frame) is dedicated to a PRACH request. A satellite radio modem for PDCH transfers is dedicated for each channel. The satellite radio modem assigned to receive the four PRACH requests is timeshared over 16 channels, thereby reducing the amount of satellite radio modems that would otherwise have been needed, had the PRACH request transmissions utilized a dedicated modem for each PRACH request, for each channel.

The invention relates to a method and a device for synchronizing one or more remote clocks (2) to a central clock (1) via a bi-directional satellite radio link (9.1, 9.2). Time and data signals are exchanged via suitable transmitting (8, 12) and receiving devices (5, 11) at both ends of the radio link. From time difference measurements (6, 14) at both ends a control signal (17) is derived in such a manner that the clock (2) installed directly in the remote ground station devices (11) synchronizes in state and rate to the central clock (1) with the aid of the two-way method (TWSTFT, Two-Way Satellite Time and Frequency Transfer). The user has access to time signals (18) which directly represent the state of the central clock (1). The signals used for the time measurement are also used for data transmission, resulting in a system operating in real time in which the control deviations (15, 16) of the remote clock are accessible at both ends of the system.
