Abstract: A back-end application computer server may access a location data store containing information about a set of locations to be visited, including location identifiers and location coordinates. The computer server may then prioritize the locations to be visited. A mobile unit data store may contain information about a set of mobile units, including mobile unit identifiers, mobile unit location coordinates, and mobile unit communication addresses. The computer server may then automatically assign each location to a mobile unit based on the location coordinates, the mobile unit location coordinates, at least one geo-fence, and said prioritization. Indications of assigned locations may be transmitted to each mobile unit via the associated mobile unit communication address, and electronic messages may be exchanged to support an interactive user interface display associated with assignments of locations to mobile units.

Abstract: A mobile device with orientation aware audio mapping capability is disclosed. The mobile device has an aux speaker, a loud speaker, a sensor for device orientation detection, and a processor (or processors) coupled to the sensor and the speakers. Depending on the device orientation, the processor sends a mapped audio output to the speakers. The mapped audio output may be a mono audio signal or a stereo audio signal. The stereo audio output signal may be a stereo audio output signal with a balanced or biased audio power distribution between the aux speaker and the loud speaker.

Abstract: The invention relates to an electronic device that includes a wake-up system that operates at a substantially low power level and is applied to wake up the electronic device from a sleep mode. The wake-up system comprises a sound transducer that converts a received sound signal to an electrical signal and a keyword detection logic that preliminarily identifies a speech energy profile that corresponds to at least one of a plurality of keywords in a part of the electrical signal. In some embodiments, a keyword finder is further activated to identify with an enhanced accuracy whether the at least one keyword exists in the part of the electrical signal, and generates a wake-up control to activate a host of the electronic device from its sleep mode.

Abstract: A system includes a plurality of channels, a parameter calculator, and an equalizer. Each channel receives a plurality of input signals that represent an input to a speaker. Each channel generates real and imaginary components of a transfer function of the speaker based on the plurality of input signals. The parameter calculator calculates a plurality of parameters of the speaker based on the real and imaginary components of the transfer function received from each channel. The equalizer adjusts the input to the speaker based on the parameters.

Abstract: An audio signal enhancement device is provided. The device includes a first and a second microphone, placed as close together as possible, the first and second microphone having receiving surfaces facing in opposing directions. The first and second microphones receive a desired target audio signal originating in the proximity of the microphones and undesired noise signals not originating in the proximity of the microphones. The acoustic pressure gradient from the desired target signal between the first and the second microphones is greater than that from the noise signals. Signal processing logic is provided. The signal processing logic is configured to firstly generate a proximity-indicator signal and a pre-target-estimate signal through a combination of output from the first microphone and output of the second microphone.
