Abstract: A method of presenting location data representing a mobile phone's current approximate location to a mobile phone user via the mobile phone display. The location information is iconically displayed and periodically updated. To display location information, the mobile phone determines its current position. Once the current position is determined, the mobile phone looks up locations within a predetermined distance from the current position of the mobile phone. The mobile phone then compares the results and selects the location/location icon pairing that is closest to the current position of the mobile phone. This location icon is then displayed on the mobile phone display. The mobile phone then waits a predetermined period before re-determining the current position of the mobile phone and repeating the search/display processes. Both the predetermined wait period and predetermined distance from the current position are user defined parameters that can be altered at the user's discretion.

Abstract: A mobile communications device has a wireless transceiver to facilitate communications, memory, and a processor. The processor may be configured to analyze an audio file stored in the memory, and extract or generate synchronizing information from the audio file. The processor synchronizes one or more complementary multi-media effects, such as lights, a camera, or a tactile feedback generator, with the audio file based on the synchronizing information. Alternatively, a user may input synchronizing information about the audio file via an interface on the communications device. The processor may then control the complementary multi-media effects in synchronization with the input synchronizing information.

Abstract: A method of sending mobile phone contact list data from one mobile phone to another mobile phone is disclosed. The sender composes an SMS or MMS message having contact data from the mobile phonebook attached. The message is sent using a messaging service like SMS or MMS to other mobile phones in a group. Before receiving mobiles act on the message, a check is determined to see if the message contains contact list data. If it does not, the message is processed normally. If the message does contain contact list data, a software program is launched to manage the received contact list data. The program displays the received mobile phone contact list data so that the mobile phone user can examine the data. An import function is run to resolve conflicts, store and overwrite data into the mobile phone's contact database based on the newly received contact list data.

Abstract: Power consumption during low-power sleep mode in a radiotelephone (104) is minimized. At a predetermined wake-up time, temperature of the radiotelephone is determined (706). A variable wake-up duration is set in response to the temperature (708). After the variable wake-up duration, the radiotelephone returns to a normal operational mode (730). In this manner, circuitry remains in the low-power state as long as possible. Further, a low-resolution secondary timer is used to measure the duration of the sleep period. After the duration timed by the secondary timer, a second duration is timed by a high-resolution primary timer. A timing calibration duration is then timed and a sleep mode is exited in synchronization with system timing.

Abstract: A radio communications device includes a transmitter, a switch, and a measurement circuit wherein the transmitter transmits radio communications at a transmitted power. The switch couples a portion of the transmitted power during spaced apart intervals of time and blocks coupling of the portion of the transmitted power between the spaced apart intervals of time. The measuring circuit measures the coupled portion of the transmitted power during the spaced apart intervals of time. The radio communications device can also include a feedback circuit that maintains the transmitted power at a desired level responsive to the coupled portion of the transmitted power.

Abstract: To differentiate between different types of modulation, a fast RSSI detector performs a RSSI measurement on a received signal. The output of the RSSI detector is sampled over a sampling window and generates sampled values. A processor calculates absolute values of piecewise first derivatives of the sampled values and sums the result to create a summation constant. A modulation detector determines the type of modulation based on the value of the summation constant and an RSSI compensation calculates a compensation factor to correct the RSSI measurement.
