Abstract: An apparatus and method for waking up a main processor (MP) in a low power or ultra-low power device preferably includes the MP, and a sub-processor (SP) that utilizes less power than the MP to monitor ambient conditions than the MP, and may be internalized in the MP. The MP and SP can remain in a sleep mode while an interrupt sensor monitors for changes in the ambient environment. A sensor is preferably an interrupt-type sensor, as opposed to polling-type sensors conventionally used to detect ambient changes. The MP and SP may remain in sleep mode, as a low-power or an ultra-low power interrupt sensor operates with the SP being in sleep mode, and awakens the SP via an interrupt indicating a detected change. The SP then wakes the MP after comparing data from the interrupt sensor with values in storage or with another sensor.

Abstract: Embodiments of the disclosed subject matter can provide techniques for synchronizing data acquisition (DAQ) modules in a data acquisition system. In data acquisition systems where multiple DAQ modules are in use, it can be desirable to synchronize the DAQ modules to facilitate the analysis of signals captured by sensors coupled to those DAQ modules. This way, a signal processing platform, such as a computer, can analyze different sensor signals (e.g., an audio sensor and vibration sensor) without separately compensating for the time difference between the audio and vibration signals. In some embodiments, the synchronization techniques can include an automatic or a semi-automatic mechanism for temporally synchronizing the sensors and for arbitrating the sampling rate between the data acquisition systems.

Abstract: Various embodiments of methods and systems for balancing user experience in a multimedia conferencing community are disclosed. An exemplary embodiment envisions a portable computing device (“PCD”) receiving data indicative of one or more visual multimedia parameter settings in a companion PCD of the community. Based on the received data, the PCD may determine an adjustment to the settings of one or more of its own visual multimedia parameters such that a multimedia output in the form of a data packet stream is adjusted. In this way, the PCD may conserve power consumption by avoiding unnecessary multimedia workload processing for encoding a multimedia output that would not benefit the quality of service (“QoS”) delivered by the companion PCD. Additionally, by optimizing the quality of the multimedia output in view of the companion device parameter settings, the PCD may allocate more of its power budget to improving its own QoS level.

A control method of the image processing apparatus is also disclosed.
