Abstract: Upon receiving a certain type of signal in a touch screen device, deactivate a portion of the touch screen, and position the deactivated portion on a edge of the touch screen such that a user can hold the touch screen device with the thumb resting on the deactivated portion, without accidentally activating icons or active links on the touch screen. The deactivated portion can be moved, cloned, and cancelled after non-use.

Abstract: A method is described for bridging a live video communication between two terminals, and then terminating the live video communication after a pre-set time period has elapsed since the live video chat. Alternatively, the live video communication will be extended beyond the pre-set time period if a request to extend the live video communication is received from one of the two terminals.

Abstract: A method is described for bridging a live video chat between two terminals, and then terminating the live video chat after a short period of time has elapsed since the live video chat, in order to reduce the pressure and fear of the parties in the live video chat. Certain attributes for the users of the terminals are calculated.

Abstract: A communications device receives a broadcast wireless communication transmission from a sender to initiate communication with the device. The received transmission includes the sender's identification, location information and other information about the transmission. The device maps relative locations of the sender and the device on a display of the device. The device also looks up a profile about the sender at a remote resource and updates the information about the sender. The device responds to the received transmissions by a broadcasting wireless communication transmission under certain situations. The remote resource may inform the sender of the profile lookup by the sender and provides the sender with the device's identification and location information.

Abstract: A cordless telephone which allows a user to play MP3 digital audio bit stream music, using the remote handset of a cordless telephone to control the functions of the MP3 player. The cordless telephone remains usable as a typical cordless telephone with all the features and conveniences of a cordless telephone including, but not limited to, connection of a telephone call between a calling party and a called party, caller ID information, voice messaging features, etc. MP3 digital audio bit stream music may be downloaded from a remote source through, e.g., the Internet and a PC.

Abstract: In one embodiment, a method of integrating a digital encoded-audio bit stream player in a radio-frequency (RF) telephone handset is disclosed. An RF connection is established between the RF telephone handset and an RF unit connected to a network, wherein communications between the RF telephone handset and the network pass through the RF unit. The RF telephone handset is switched from performing as a telephony device to performing as a digital encoded-audio bit stream player. Digital encoded-audio bit stream music is played from the RF telephone handset. The digital encoded-audio bit stream music playing from the digital encoded-audio bit stream player is muted when the RF telephone handset receives a telephone call. The RF telephone handset is switched from performing as a digital encoded-audio bit stream player to performing as a telephony device while the telephone call is active.

Abstract: A cordless telephone which allows a user to play MP3 digital audio bit stream music, a video game, either alone or with a user of another cordless telephone, using the remote handset of a cordless telephone to control the functions of the MP3 player. The cordless telephone remains usable as a typical cordless telephone with all the features and conveniences of a cordless telephone including, but not limited to, connection of a telephone call between a calling party and a called party, caller ID information, voice messaging features, etc. MP3 digital audio bit stream music may be downloaded from a remote source through, e.g., the Internet and a PC.

Abstract: A baseband clock synthesizer having particular use in a BLUETOOTH piconet device, having the capability of generating either 12 MHz or 13 MHz clock signals generated from any reference clock signal, e.g., 12.00, 12.80, 13.00, 15.36, 16.80, 19.20, 19.44, 19.68, 19.80, and 26.00 MHz. A fractional-N frequency divider is implemented with a PLL including a variable divider allowing the use of virtually any reference frequency input to generate a locked 156 MHz clock signal used as a basis for a 12 MHz or 13 MHz baseband clock signal. A residue feedback sigma-delta modulator provides a varying integer sequence to an integer divider in a feedback path of the PLL, effectively allowing division by non-integer numbers in the PLL. Thus, the PLL can be referenced to virtually any reference clock and still provide a fixed output clock signal (e.g., 12 or 13 MHz).

Abstract: A single coder/decoder shared among several multiprocessors in a digital signal processing system through time-division multiplexing between multiple processors to enhance signal processing capabilities by assigning different digital-to-analog channels to different processors for digital-to-analog conversion, while allowing all processors to operate on the same analog-to-digital data for analog-to-digital conversion, thereby resulting in chip area reduction and power consumption saving.

Abstract: The present invention provides a baseband RF clock synthesizer having particular use in a BLUETOOTH piconet device, which has the capability of providing simple and accurate calibration of modulation path gain (KMOD) by introducing a dual-loop phase locked loop (PLL) in the RF clock signal synthesizer. The disclosed technique and apparatus controls the maximum frequency deviation by the difference of two locked frequencies, one frequency in each path of the dual-path PLL. Once the PLL is locked within some frequency error, the present technique and apparatus calibrates for the deviation of amplitude of the modulation due to the modulation path. Accordingly, modulation gain (KMOD) calibration is provided by adding an auxiliary loop to a PLL in an RF frequency synthesizer.
