摘要： Aspects of the present disclose involve a method, a device, and a system comprising a processor and a machine-readable storage medium storing a set of instructions for providing audio level safeguards for output audio signals. In example embodiments, the method includes accessing a most recent audio level of an audio output device and determining whether the most recent audio level transgresses a threshold value. Based on determining the most recent audio level transgresses the threshold value, a current audio level output by the audio output device is set to the threshold value. Thereafter, the current audio level is gradually increased, at repeated time intervals, until it reaches the most recent audio level.

摘要： An example implementation involves a first playback device receiving audio content to be played back by the first playback device and a second playback device in synchrony. Such audio content may include a first and second stereo component. The first playback device determines a limiting result that indicates frequencies at which a playback volume of the second playback device is limited and determines a crossover frequency based on the indicated frequencies at which the playback volume of the second playback device is limited. The first playback device causes the second playback device to play a first portion of the second stereo component that is above the determined crossover frequency and plays (i) the first stereo component and (ii) a second portion of the second stereo component that is below the indicated frequency in synchrony with playback of the first portion by the second playback device.

摘要： An image sensor array that has a plurality of image sensing pixels and a plurality of programmable gain amplifiers, each of the programmable gain amplifiers connected to receive and amplify an output of said image sensing pixels. Each of said programmable gain senses when an output of the programmable gain amplifier is in an oversaturated condition. Responsive to sensing that the output of the programmable gain amplifier in the oversaturated condition, the amplifier automatically clamps a bias amount to the programmable gain amplifier, to thereby regulate an amount of current draw of the programmable gain amplifier. In this way, the power supply current to that pixel which is oversaturated is prevented from affecting power supplies to the other pixels, by regulating the power supply to the oversaturated pixel.

摘要： A limiter for high-frequency signals has an input, whereas the high-frequency signal is supplied to the limiter at its input. The limiter provides several limiting stages which are electrically connected to the input. Each limiting stage is a series circuit with an unbiased diode and a Zener diode which does not serve to bias the diode, so that the high-frequency signal is electrically connected to a reference ground via the one unbiased diode and the Zener diode.

摘要： A method of operating a speaker system including a speaker coupled to an amplifier, and a dedicated digital speaker protection circuit includes turning on the amplifier in a mute mode, after a first delay period, issuing a play command to the amplifier to place the amplifier in a play mode, but without an input signal during a second delay period, and performing a speaker offset detection during the second delay period, wherein, if there is an offset, then the amplifier is forced back into the mute mode, and if there is no offset, then the amplifier is allowed to continue to operate in the play mode. The method also includes issuing a speaker protection control signal or command if an offset is detected.

摘要： A monolithic integrated circuit (IC), and method of manufacturing same, that includes all RF front end or transceiver elements for a portable communication device, including a power amplifier (PA), a matching, coupling and filtering network, and an antenna switch to couple the conditioned PA signal to an antenna. An output signal sensor senses at least a voltage amplitude of the signal switched by the antenna switch, and signals a PA control circuit to limit PA output power in response to excessive values of sensed output. Stacks of multiple FETs in series to operate as a switching device may be used for implementation of the RF front end, and the method and apparatus of such stacks are claimed as subcombinations. An iClass PA architecture is described that dissipatively terminates unwanted harmonics of the PA output signal. A preferred embodiment of the RF transceiver IC includes two distinct PA circuits, two distinct receive signal amplifier circuits, and a four-way antenna switch to selectably couple a single antenna connection to any one of the four circuits.

摘要： An arrangement and method for converting an input signal z(t) into a mechanical or acoustical output signal p(t) comprising an electro-magnetic transducer using a coil at a fixed position and a moving armature, a sensor, a parameter measurement device and a controller. The parameter measurement device identifies parameter information P of an nonlinear model of the transducer considering and the saturation and the geometry of the magnetic elements. A diagnostic system reveals the physical causes of signal distortion and generates information for optimizing the design and manufacturing process of this transducer. The controller compensates for nonlinear signal distortion, stabilizes the rest position of the armature and protects the transducer against mechanical and thermal overload.
