    摘要: A photoconductive switch comprises a first layer (1), two contact layers (2, 3) arranged on said first layer and connectable to different potentials for applying a voltage thereacross, said first layer being adapted to be conducting upon applying a voltage across said contact layers when exposed to light from an illumination source of an energy high enough for lifting charge carriers from the valence band to the conduction band of the material of said first layer. The illumination source is an excimer lamp, in which unstable electronically excited dimers are formed when a voltage is applied across first and second electrodes (12, 13) separated by a gas or gas mixture. The dimers so formed decompose into two gas atoms while emitting a photon of an energy suitable for lifting charge carriers from the valence band to the conduction band of the material of the first layer.

    摘要: A sound reproducing device has a loudspeaker arranged to produce sound from an audio signal provided by an audio signal source. A microphone is positioned to pick up ambient noise and generate a microphone signal which comprises the noise. An ambient noise cancellation (ANC) system receives the microphone signal from the microphone and generates anti-noise corresponding to the ambient noise in the microphone signal. An automatic polarity adaptation (AAP) system monitors the ANC system and, when a decision criterion is fulfilled, causes a switch in polarity for the generated anti-noise.

    摘要: The present invention provides adapting an audio frequency range to a linear vibrator. This may be achieved by detecting presence of signal components in a first audio frequency range. A control signal may then be provided in response to the detected first signal components. A second signal component in a second frequency range may moreover be obtained and controlled in response to the amplitude of the control signal, wherein the second frequency range is narrower than the first audio frequency range. Feeding of the controlled second signal component to the linear vibrator causing vibrations of the linear vibrator is thus enabled, creating an increased experience of the music when applied to rhythm-based music within a portable communication device such as a mobile phone.

    摘要: A microphone circuit includes a first microphone, a second microphone, an adjustable delay unit, and a combiner. The first microphone generates a first microphone signal that includes a contribution associated with an output signal that is generated by a loudspeaker in response to an input signal. The second microphone generates a second microphone signal that includes a contribution associated with the output signal from the loudspeaker. The adjustable delay unit delays the second microphone signal relative to the first microphone signal by a delay value. The combiner combines the delayed second microphone signal and the first microphone signal to provide a combined microphone signal. The adjustable delay unit adjusts the delay value so as to reduce at least a portion of the contribution to the combined microphone signal that is associated with the output signal from the loudspeaker.
