Abstract: A power supply includes a connector, a power conversion controller to generate a power supply signal at the connector, and a communication and control processor. The communication and control processor is to receive a set of current control parameters including a current limit over a communication link in the connector, receive measurements of current and voltage of the power supply signal, and generate a drive signal for controlling the power conversion controller based on the received current control parameters and the measurements of the current and the voltage.

Abstract: A power supply system is operable to contemporaneously supply power to multiple output ports when available power from a power source is insufficient to meet maximum potential power requirements of load devices coupled to the output ports. The power supply system includes a system monitor, multiple power converters, and optional temperature sensing circuits, where each power converter supplies power to a respective output port. The system monitor monitors an output power characteristic of the power source, output powers delivered to the output ports, and/or temperatures detected by the temperature sensing circuits. When the system monitor detects an overload condition is approaching based on the monitored parameter or parameters, the system monitor generates control signals which cause the power converters to maintain or reduce their output powers such that the overload condition is abated and two or more output ports continue to deliver output power to their respective load devices.

Abstract: Received data is filtered to produce pre-noise suppression data. Noise is removed from the pre-noise suppression data to provide noise-suppressed data. At least one weighted filter coefficient is dynamically determined using at least the pre-noise suppression data and not the noise suppressed data. The determination occurs independently from and is not affected by removing the noise from the pre-noise suppression data. Removing the noise from the pre-noise suppression data occurs independently from and is not affected by dynamically determining the at least one weighted coefficient.

Abstract: A method is described for launching a vehicular camera application residing on a docked mobile communication device, such as a smartphone, tablet computer, or mp3 player, for example. A common feature for the many choices of a mobile communication device is that the mobile communication device comprises embedded data processing capability. The launching operation of the vehicular camera application includes detecting a communicative coupling of the mobile communication device with a docking device; and thereafter initiating the vehicular camera application that resides on the mobile communication device. Images are displayed on the mobile communication device that was captured by a vehicular camera or a camera integrated with the mobile communication device or communicatively coupled to the mobile communication device.

Abstract: A method for recording a geographical location from a docked mobile communication device that includes detecting a mobile communication device communicatively coupled to a docking device; and detecting that the mobile communication device is communicatively uncoupled from the docking device. Afterwards, the geographical location of the mobile communication device is recorded and stored in memory upon detecting that the mobile communication device has communicatively uncoupled from the docking device.

Abstract: A transmitter device (100) receives an audio signal from an audio source device (112), and transmits the audio signal at a low power over a commercial broadcast channel to a local receiver (120). The transmitter device selects an initial channel by scanning the available spectrum, partitioned into sub-bands (210-206), and measuring the received signal strength in each channel. The channel having the lowest strength is used to set a threshold. The sub-band with most channels meeting the threshold is initially selected, and the channel in the initially selected sub-band with the lowest received signal strength is selected for initial use. A context-based weighting factor may be applied in selecting the initial channel or in selecting subsequent channels when the initial channel conditions degrade.

Abstract: Described are methods and systems to preset a Bluetooth enabled headset and a Bluetooth enabled conference hub, so that at the time of a conference call, they are pre-paired and ready for use. Pairing information of a particular Bluetooth headset may be stored with a server and downloaded to a particular conference at the time of the scheduled conference. When a conference call is scheduled, via for example an email client conference scheduling tool, the hub will be automatically preset so that when a particular user with a headset comes within range, the headset and hub are paired and may transmit and receive communications between them. The described methods and systems can be used in large scale and small scale businesses with dynamic conferencing needs. The methods and systems can integrate with widely available email client conference scheduling tools currently used by many business enterprises.

Abstract: An echo canceller circuit (200) and method performs cascaded echo cancellation and noise suppression in a non-interfering manner. The echo canceller circuit (200) includes pre-noise suppression logic (210), echo canceller coefficient logic (218), noise suppression logic (212) and an echo canceller filter (216). The pre-noise suppression logic (210) receives pre-echo canceller uplink data (64) and downlink data (52), and in response produces pre-noise suppression uplink data (224). The echo canceller coefficient logic (218) receives the pre-noise suppression uplink data (224) and the pre-echo canceller uplink data (64), and in response produces filter coefficient data (226). The noise suppression logic (212) receives the pre-noise suppression uplink data (224), and in response produces noise suppressed uplink data (228). The echo canceller filter (216) receives the noise suppressed uplink data (228) and the filter coefficient data (226) and in response produces final uplink data (230).

Abstract: A method (200) for controlling audio signals to an FM transmitter and a loudspeaker of a hands-free adapter first sends a first audio signal to the loudspeaker (242) and measures and records a loudspeaker audible artifact such as echo return loss (244) and/or echo tail length (246). Next, the hands-free adapter sends a second audio signal to the FM transmitter and the loudspeaker (252) and measures and records an FM transmitter and loudspeaker audible artifact such as echo return loss (254) and/or echo tail length (256). If the FM transmitter and loudspeaker audible artifact minus the loudspeaker audible artifact is greater than a threshold (263, 266), the hands-free adapter sends a third audio signal to the FM transmitter only (270), and if the FM transmitter and loudspeaker audible artifact minus the loudspeaker audible artifact is not greater than the threshold, the hands-free adapter sends the third audio signal to both the FM transmitter and the loudspeaker (280).

Abstract: A portable hands-free phone accessory (102) provides hands-free operation for a mobile communication device (104), and is operable in an operating mode for providing hands-free operation, and a low power, battery saving mode which does not provide hands-free operation. When the accessory is in the low power mode, it periodically checks to if a phone device has come within a hands-free range (204). When a phone device is detected, the accessory powers up for hands-free operation. When the accessory in the operating mode, and detects that the phone has moved away from the accessory (304), the accessory powers down to the low power mode.
