US Classification:

4555751, 455 903, 455128, 455106, 714 22, 174370

Abstract:

A wireless device having a remote station portion, such as a cellular telephone, PDA, laptop computer, handheld computer, or the like and a removably connectable medical device portion, such as a blood glucose monitor or the like, is provided. The medical device portion is separated from the remote station portion by an isolation circuit and electromagnetic shielding to inhibit the electronics and radio frequency transmission of the remote station portion interfering with the medical device. Moreover, a control processor in the remote station portion has a battery management module to disable functions as the charge in the power source falls to provide sufficient power for operation of the medical device.

Inventors:

Yang Zhang - San Diego CA, US
Jack Steenstra - San Diego CA, US

Assignee:

QUALCOMM Incorporated - San Diego CA

International Classification:

H01Q 1/50

US Classification:

343906, 343872

Abstract:

A digital mobile TV transceiver having improved performance is integrated as a USB dongle device for wireless devices. The antenna is not readily obvious to the user as it is hidden in the swing arms and cap of the device. The extendable arms act as telescoping antenna that increase the antenna length for improved antenna performance in the frequency range of 700 to 780 MHz. The antenna can swing into a position away from the body of the device, greatly improving the antenna gain performance and its radiation patterns. In addition, the antenna can be top-loaded design with dielectrics in the cap to further improve its performance. The USB transceiver comprises a USB adaptor, a retractable antenna, and a cap for protecting the USB adaptor when the antenna is retracted. The adaptor, antenna and cap lie in a plane rotatable by 360 degrees.

International Classification:

H04M 11/04
H04W 24/00

US Classification:

4554041, 4554042, 4554561

Abstract:

Implementations relate to systems and methods for localized notification that provide localized information to one or more mobile devices in a wireless communication system that are located in one or more geographical regions. The wireless communication system includes a localized notification server that responds to geographically-targeted broadcast requests and localized service or information requests. The localized notification server localizes components of the wireless communication system into sets of localized components that provide wireless communication service to mobile devices in the specific geographical regions. In response to a request to broadcast to a target geographical region, the localized notification server identifies a set of localized components associated with the target geographical region. The localized notification server then broadcasts information to mobile devices actively serviced by the set of localized components.
