    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： The invention is directed to systems, methods and computer program products for adjusting audio properties after recording an audio. An exemplary method includes recording audio using an audio capturing system, wherein the recorded audio is associated with an audio level; determining one or more audio signal properties associated with the recorded audio; comparing the audio level with a first predetermined threshold level; and in response to determining the audio level is greater than a first predetermined threshold level, adjusting the recorded audio based at least partially on modifying the one or more determined audio signal properties, wherein the adjusting step is performed a finite time interval following the recording step.

    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.
