Abstract: A touch sensitive navigational surface functions as a user interface to a communication device such as a cellular telephone. An electromechanical dielectric (EMD) film coextensive with at least a portion of the surface of the cover of the device selectively functions as a sensor, microphone or speaker. The EMD film is placed behind a display to provide a user interface touch sensitive screen capable of sensing the direction of touching. At least a portion of the EMD film functions as a fingerprint recognition system to provide security means for controlling access and limiting call completion to an authorized user.

At least one of the mobile communication base facility and the supported unit have on-line access to an information store and a locator.

Abstract: Described is a way for computing proximity (location-based proximity or preference-based proximity) between mobile wireless subscribers (who use different services) without either divulging their location/preference to the other (preservation of privacy). Privacy is kept by providing location/preference information in steps, along with an evaluation function. The services receive partial results and then locally compute the final result, or proximity. The term proximity includes not just physical proximity but also multi-dimensional data such as preference profiles and vectors (e.g., an affinity for baseball, apple pie, and ballroom dancing).

Abstract: A recharge apparatus for holding the rechargeable device and battery includes the cradle top and the cradle base. The cradle top includes the elastic gate, the battery-fixing clip, and the charge area. The elastic gate is an opening for inserting the rechargeable battery, and capable of rebounding against pressure so that the elastic gate does not clip the user's finger during operation, and also enhances the appearance as well as being dust-proof. The battery-fixing clip is used for clipping the rechargeable battery tightly. The charge area is an inserting area for charging the rechargeable devices, and has a stand pin to hold the rechargeable devices steadily by inserting the stand pin into the bottom of the rechargeable device. The cradle base assembled with the cradle top includes the elastic joint and recharge PCB (printed circuit board). One end of the elastic joint is designed as the upward curve to touch the rechargeable battery.

Abstract: A method of conveying electronic information from a stationary or mobile device such as a vending machine (1) to a mobile telephone network (14). The method comprises taking at least partial temporary control over the mobile terminal to provide temporary connectivity to a mobile telephone network via a wireless communication link between the mobile or stationary device and said terminal, transmitting the information from the stationary or mobile device (1) to a mobile terminal (8) in close proximity to said device (1) via a wireless communication link (RI1). The information is then relayed from the mobile terminal (8) to the mobile network (14) via the mobile network radio link (RI2).

Abstract: In a code division multiple access wireless communication system having at least one base transceiver station and at least one mobile station having a mobile station receiver assembly configured to receive a coded signal having an information-bearing signal portion and an associated interfering signal portion from the base transceiver station, a method and apparatus for automatic gain control compensation in the mobile station receiver assembly, is disclosed. The method includes causing a gain adjustment to the coded signal by an AGC circuit in the mobile station receiver assembly to produce a post-AGC signal having a post-AGC interfering signal portion with an associated post-AGC interfering signal power level, and an associated gain error value. The method further includes compensating for the gain adjustment to the coded signal if the number of receiver fingers assigned to demodulate the coded signal is less than or equal to a predetermined number.

Abstract: Double balanced mixers having transistor pairs are affected by area mismatches between the transistors. The area mismatches can be represented as a ratio between the mixer core transistors that is directly related to voltage. Thus, an input voltage into one of the mixer core transistors in a transistor pair can compensate for the area mismatch. The compensation is achieved by a voltage track and hold feedback loop to one of the mixer core transistors.

Abstract: Method and processor for determining loading of a communications system shared by a plurality of user-terminals are provided. The method allows a respective terminal for monitoring a control channel including logical messages therein. The monitoring of the messages in the control channel is performed regardless of whether or not the logical messages therein are specifically addressed to that terminal. The method further allows for estimating a parameter indicative of system loading based on information in the monitored logical messages.

Abstract: A system is provided which combines the advantages of Adaptive Antenna Arraying and Adaptive Locally-Optimum Detection, as well as Adaptive Filtering, signal processing techniques and achieves the capabilities of all these techniques. The present invention represents the first successful integrated system for performing signal processing techniques associated with an Adaptive Antenna Array (AAA) system and an Adaptive Locally-Optimum Detection (ALOD) system. The system automatically distributes interference signals among Adaptive Antenna Arraying and Adaptive Locally-Optimum Detection sub-systems according to which sub-system's algorithms can provide a more optimum suppression of the interference signals. The system permits an adaptive antenna array with a given number of antenna elements to effectively suppress a larger number of interferers than it otherwise could, and to adapt more quickly to a rapidly changing interference scenario.

Abstract: A start value is x bits in size and is used to provide an initial value to an n-bit security count value. A wireless communications device establishes channels with a compatible device, and releases channels established with the compatible device. For every channel established by the wireless communications device, a corresponding terminal value is obtained. A terminal value for a channel is the highest value reached by the x most significant bits (MSBX) of an n-bit security count value associated with the channel. The security count value is used to encipher data transmitted along the channel. A final value that is obtained that is the greatest value of all the terminal values. Finally, a start value is stored in the memory of the wireless device that is at least as large as the final value.

Abstract: A method of storing electronic data in a system having a mobile terminal (8) and a remote system (1), the mobile terminal (8) and the remote system (1) interacting with each other to exchange electronic data. In order to prevent data loss at the mobile terminal (8), data storage capacity and storage requirements are monitored at the mobile terminal (8). If a risk exists that the data storage capacity of the mobile terminal (8) is likely to be exceeded, electronic data from the mobile terminal (8) is uploaded to the remote system (1), and stored there. The previously uploaded data is subsequently downloaded from the remote system (1) to the mobile terminal (8) in the event that that data is required by the mobile terminal (8) or a determination is made that the risk of exceeding the data storage capacity of the mobile terminal (8) no longer exists.

Abstract: Radio network subsystems (RNSs) are provided that are in communications with a core network (CN). One of the RNSs is an SRNS, and another RNS is a target RNS (TRNS). The SRNS is in wireless communications with a mobile unit to provide service data units (SDUs) from the CN to the mobile unit. The SRNS associates a sequence number (SN) with each of the SDUs, and the mobile unit is capable of confirming to the SRNS SDUs received from the SRNS. Forwarding information is provided by SRNS to the TRNS. The forwarding information includes SDUs unconfirmed as received by the mobile unit, a first SN that is the SN of the sequentially earliest unconfirmed SDU, and a second SN that is the SN of the sequentially last unconfirmed SDU actually transmitted to the mobile unit by the SRNS. Finally, the TRNS is made the new SRNS for the mobile unit.
