In order to manage power on a wearable computing device, a processor of the wearable computing device identifies one or more events. The processor determines a priority of each of the one or more events. Based on the priority of each of the one or more events, the processor determines whether to process the event. When the processor determines that the event is to be processed, the processor determines whether to defer processing of the event.

Power management systems and methods for a wearable computing device

A method of controlling a portable electronic device includes detecting a touch on a touch-sensitive display, adjusting a first threshold based on detected conditions during the touch, comparing a value related to the touch on the touch-sensitive display to the first threshold, and when the value related to touch meets the first threshold, turning off the display.

A voicemail system utilizing a wireless handheld device with a suitable user interface for presenting voice messages and email messages is disclosed. Voice messages are received over a wireless network, and stored on the handheld device. Upon receipt of a voice message, the handheld device records the audio message in local memory. Subsequently a message record entry corresponding to the received audio message is displayed in a user interface screen of the handheld. When the user opens the displayed message record, the handheld device plays back the corresponding audio message stored in local memory.

A system and method are provided that can be used for applying a deblocking filter to a video according to processor usage, in particular on a mobile device. To determine which of a plurality of deblocking filters to use, the system determines an environment indicator indicative of current processor usage, compares the environment indicator to a primary threshold, wherein the primary threshold is indicative of a maximum acceptable processor usage. If the primary threshold is met, the system foregoes any deblocking filtering. If however the primary threshold is not met, the environment indicator is compared to one or more secondary thresholds and a respective one of the plurality of deblocking filters is applied to the video according to which one of the secondary thresholds is met. Each of the plurality of deblocking filters has a different complexity and thus can be chosen to suit the current system environment.

A processor and method are provided for decoding a multimedia file having video and audio data streams that are configured to be played in synchronization. Frames of the video stream are decoded and played with the audio and, to compensate for saturation of the processor usage, two procedures are performed. The first procedure operates at a first periodic interval and slows down the frame rate to reduce processor usage if needed. The second procedure first attempts to speed up the video to catch up to the audio if they are out of sync and if this cannot be done in the next time interval, the decoding of a select number of frames is skipped such that the video and audio data streams are resynchronized.

Method and arrangement for affecting diagonal movement of a cursoron a display screenof a handheld communication device. The method includes sensing movement at an auxiliary user inputof the handheld communication deviceindicative of a user's desire to affect diagonal movement of the cursoron the display screenof the handheld communication device. X-direction signals and Y-direction signals are produced based on the sensed movement at the auxiliary user input. During that time while necessary signals are being collected and processed, the cursoris held steady on the display screenuntil a predetermined criterion is met for discriminating whether the user has indicated x-direction cursor movement, y-direction cursor movement or diagonal cursor movement.

The invention is directed at a headset for a mobile communication device having a multi-button control and is implemented with a standard headset jack. The multi-button control is decoded by a microprocessor after which an encoded signal is then transmitted from the processor to the handset. In this manner, by using the standard jack, no additional hardware is required on the handset.

The disclosure provides a circuit and method for activating an electronic device from a low power state. The activation circuit comprises: a first accelerometer in the device; a second accelerometer which is activated upon receiving a movement signal from the first accelerometer; an input device; and a circuit to provide power to the input device when a series of connected movements signals from at least one of the first and the second accelerometers match a predetermined movement gesture.

The disclosure relates to a system and method for adjusting a characteristic of a data transmission in order to maintain a rate of transmission. For the method, it comprises: monitoring for initiation of the data transmission to the device; identifying characteristics of the device relating to the data transmission; automatically adjusting the transmission rate according to a preset transmission rate progression established for the communication network; and adjusting characteristics of the data transmission to allow the characteristics of data transmission to conform to the characteristics of the device while maintaining the transmission rate for the device.

Method and arrangement that provides a power-saving mode for a handheld electronic device having a reduced alphabetic keyboard. The power-saving mode is enabled through disabling a sensor that detects motion of a ball of the trackball navigation tool and disabling the display screen of the handheld electronic device. The power-saving mode may be exited before disablement of the sensor when the display screen is disabled first.

A touch screen display of an electronic device is calibrated. The method includes receiving input comprising selections of features registered at the touch screen display, filtering the input based on characteristics determined during the receiving to determine if the input is to be used for calibrating, for each input used for calibrating, determining a difference between registered touch location and a respective target for the selection and subtracting an offset from the difference, thereby providing remainders of differences for the selections, and calibrating by adjusting a prior calibration based on the remainders if the input is determined to be used for calibrating.

Various embodiments are described for a mobile communication device having a main processor for controlling the operation of the mobile communication device; a device memory coupled to the main processor for storing a plurality of battery information profiles; and a smart battery coupled to the main processor for providing supply power. The smart battery includes a battery processor for controlling the operation of the smart battery and communicating with the main processor; and a battery memory coupled to the battery processor for storing a Battery ID indicating the model of the smart battery. The main processor is configured to communicate with the battery processor to obtain the Battery ID and to select one of the battery information profiles based on the Battery ID.

System and method that provides tactical feedback through a speaker of a handheld electronic device having a full alphabetic keyboard upon activation of a navigation tool. The audible feedback produced by the speaker is capable of being modified based on upon the location, speed, and other characteristics of the movement of a cursor on the display of a handheld electronic device. The sound produced by the speaker can originate from an audio file stored or otherwise available on the handheld electronic device.
