This document describes techniques and systems relating to isolation slots for an antenna and printed circuit board (PCB) interface of a radar system. For example, isolation slots may be etched on a metal surface layer of a PCB for a radar control module on each side of each transmission line (e.g., microstrip line) that forms an array of channels (e.g., transmit channels, receive channels). When the PCB and an antenna structure are mated, a gap exists along the mating plane in which energy leakage between the channels can occur. The isolation slots create a stop band for a certain range of frequencies of interest and may reduce this energy leakage even when the gap is uneven along the mating plane. The isolation slots may be relatively easy and inexpensive to manufacture. The gap along the mating plane is not required to be constant, further simplifying the manufacturing process.

A method for performing a detach of a terminal registered to a telecommunication network is disclosed. The detach is performed by associating an identification for the terminal, deriving a signature for the identification, and allocating a pair consisting of the identification and the signature to the terminal. The method further includes sending the detach request including the identification and the identification signature from the registered terminal to the network. The detach request is received at the network and compared to a record of registration data of the terminal kept at the network. The terminal is detached from the network if the received detach request coincides with the record of registration data.

A system and method for carrying out wireless communications at a vehicle, wherein the vehicle comprises a wireless communications device and a plurality of vehicle system modules, wherein the method is carried out by the wireless communications device. The method can include the steps of: receiving an anticipatory vehicle ignition termination signal; setting the wireless communications device to operate in a station mode; detecting the presence of a wireless access point using the wireless communications device in the station mode; providing an indication to at least one of the vehicle system modules of the presence of the wireless access point; establishing a wireless connection between the wireless communications device and the wireless access point; and communicating data between the wireless access point and one or more vehicle system modules via the established wireless connection using the wireless communications device.

The present invention relates to a method for selecting and downloading content from a content provider which is accessible via an IP/DNS/URL address to a mobile device, the content being any text information data, for converting the text information data to at least one audio message and for storing the at least one audio message as at least one audio file on the mobile device, wherein the at least one audio file is playable and discernable as a music file. Said method implemented on a mobile phone enables controlling and playing the audio messages as music files by determining a short title associated with the audio file using word underline and size attributes of the text, for user selection on the mobile's graphical user interface, for instance also in a car environment with a car kit enabling a control and a selection of one or more of said at least one audio files for playing from the mobile phone.

A method of managing speech interfaces to computer-based services includes beginning a first speech session that is carried out in a vehicle over a short-range wireless connection between a vehicle occupant and a mobile device; detecting an initiation of a second speech session while the first speech session is being carried out; determining an assigned priority level of the first speech session relative to an assigned priority level of the second speech session based on a first speech context identified in the first speech session and a second speech context identified in the second speech session; and when the assigned priority level of the second speech session has a higher priority than the assigned priority level of the first speech session, carrying out a session-appropriate action on the first speech session.

A vehicle-mounted communication device, which consumes less electric power, and a method of controlling the vehicle-mounted communication device are provided. The vehicle-mounted communication device includes a modem 12, which is configured to perform wireless communication via a portable telephone network, a judgment part 183, which is configured to judge whether the modem 12 is in a wireless communicable state, and a judging timing determination part 184. The judging timing determination part 184 is configured to stop the judging operation of the judgment part 183 until a predetermined condition is satisfied, when the judgment part 183 judges that the wireless communication is not in an enabled state while a driving source of a vehicle is stopped.

Various embodiments may include a computer-implemented method and system for operating a computer application stored on a nomadic wireless communication device (ND) located within the vicinity of a vehicle. An input may be received at a vehicle computer system (VCS) to pair the VCS with the ND for establishing a wireless communication link. A number of instructions may be received at the VCS from the ND over the wireless communication link. The instructions may include instructions for establishing a connection with an internet radio application and instructions for prompting a user for one or more internet radio application events. A request from the user for the one or more internet radio application events may be received at the VCS and the one or more internet radio application events may be executed.
