Abstract:
A geographical field is displayed including indicia, representing respective items stored in a navigation system, that are displayed in positions that correspond to geographic relationships of the items on the geographic field. In response to a user manipulating a user interface control device, a visible feature of the geographic field is altered to indicate browsing with respect to a predetermined succession of the stored items.
Abstract:
A frame receives a portable media player. The frame includes connection elements to provide electrical connection between the portable media player and a vehicle media system, and a guide to align the portable media player with the connection elements. A case for a portable media player has an interior space configured to accommodate different configurations of portable media players, and an exterior configured to fit within a receptacle of a vehicle. A cup has an interior space configured to receive a portable media player and a coupler to provide electrical connection between the player and a media system. Sending a command to the portable device causing the portable device to enter a sleep state when the vehicle off, reducing a level of drain by the portable device from a power source of the vehicle. A portable media player may be controlled by the vehicle media system.
Abstract:
Techniques for providing self-voice feedback in a communications headset include processing signals carrying near-end speech in parallel digital and analog signal processing paths to produce a combined gain-adjusted near-end signal carrying the near-end speech for output to transducers of the communications device. A first and a second microphone (202, 204) provide first and second signals from which a first signal processing circuit (212) determines a microphone mixing parameter value and a gain adjustment parameter value. The first signal processing circuit mixes and the first and second signals to produce a gain-adjusted outbound signal. A second signal processing circuitry produces a combined gain-adjusted near-end signal carrying near-end speech for output to transducers (206, 208) in first and second earcups.
Abstract:
An audio system for manipulating audio material for playback based on the content of the material includes an input for receiving input audio signals, an output for providing output audio signals to loudspeakers, and an audio processor that processes the input audio signals to produce the output audio signals. The audio processor determines a type of content represented by the input audio signals, selects a set of processing instructions to control the spatial presentation of the audio material based on the determined type, and applies the selected set of processing instructions to the input audio signals.
Abstract:
A method for managing presets in an audio system is provided. The method includes syncing preset assignments on a plurality of audio playback devices such that preset assignments on any one of the audio playback devices correspond to respective preset assignments on each of the other audio playback devices, and, such that, if one of the preset assignments is changed on one of the audio playback devices, each of the other audio playback devices is automatically updated such that a corresponding change is made to a corresponding preset assignment on each of the other audio playback devices. Each of the preset assignments is an assignment of an entity associated with one of a plurality of digital audio sources to one of a plurality of preset indicators on the corresponding one of the audio playback devices.
Abstract:
A device for coupling to a connector on an ear cup of a headset includes a mating connector corresponding to the connector of the headset. The mating connector includes a crossover conductor coupled to a first and a second terminal within the mating connector. One or more accessory circuits is provided by the device, including a lamp configured to direct light onto a surface external to the device or a position detection circuit usable to adjust three-dimensional audio signals to account for the direction the user is looking.
Abstract:
In response to receiving an indication at a primary device of initiation of a communication mode change, the primary device transmits a first command. Each of one or more secondary devices that are in a responsive state when the first command is transmitted responds to the first command with a response message and remains in a responsive state until a second command is received from the primary device. Each secondary device that is not in a responsive state when the first command is transmitted changes to a responsive state after a predetermined amount of time in a non-responsive state and remains in a responsive state for at least a minimum time duration. The primary device collects response messages received from secondary devices, and in response to the number of response messages received being equal to an indicated number, transmits the second command.
Abstract:
Apparatus and method to mix first and second audio channels provided to a headset in response to the quantity of audio devices coupled to its connectors, in response to whether any of those audio devices provides more than one audio channel, and in response to their being a complete lack of electric power provided by any audio device and from a power source of the apparatus, itself.
Abstract:
A power conversion device includes a magnetic core; and a plurality of windings surrounding portions of the magnetic core, including a first winding and a second winding magnetically coupled through the magnetic core. The magnetic core comprises a first part formed of a first material and a second part formed of a second material, the first material having a first stiffness and the second material having a second stiffness substantially less than the first stiffness. The first winding and the second winding are magnetically coupled through the first part of the magnetic core.
Abstract:
A portable loudspeaker includes an electro-acoustic driver which creates sound waves when operated and a housing having a front side to which the driver is secured. The loudspeaker also includes a battery supported by the housing for providing electrical power to the driver and a cover secured to the housing which can be moved between (i) a closed position in which the cover overlies the driver, and (ii) an open position in which the cover does not overlie the driver. A controller controls operation of the loudspeaker. When the cover is moved to the closed position, a feature on the cover causes an indication to the controller that the cover is in the closed position. In response to the indication, the controller mutes the driver if the driver was outputting acoustic waves when the cover was moved to the closed position.
