Abstract: A receiver-audio-device and a transmitter-audio-device. The receiver-audio-device comprises a receiver-ultrasound-receiver, configured to receive transmitter-ultrasound-signals representative of a request, from a transmitter-audio-device, for complementary audio resources; and a receiver-processor, configured to generate a complementary-audio-output-signal based on at least the transmitter-ultrasound-signals and to provide the complementary-audio-output-signal to a receiver-loudspeaker. The receiver-loudspeaker is configured to provide a complementary-audio-output based on the complementary-audio-output-signal. The transmitter-audio-device, comprising: a transmitter-ultrasound-transmitter, configured to provide transmitter-ultrasound-signals representative of a request for complementary audio resources; a transmitter processor, configured to generate an audio-output-signal and to provide the audio-output-signal to a transmitter-loudspeaker.

Abstract: There is provided an architecture for a data processing platform using a dedicated security device for user interaction, the data processing platform (100, 200) comprising: a processing device (108); a security device (102) communicatively coupled (114) with the processing device (108), the security device (102) being adapted for receiving input data (116) and providing the input data (116) to the processing device (108) only if the input data (116) are associated with a predetermined security level range, e.g. if the processing device (108) is in a secure operating mode or if input data (116) are considered by the security device (102) to have a security level in the predetermined security level range.

Abstract: A pixel structure for CMOS imaging applications, the pixel structure including a photosensitive element, a load transistor in series with the photosensitive element, a first reading transistor, coupled to the photosensitive element and to the load transistor, for reading out signals acquired in the photosensitive element and converting the signals to a voltage drop across the load transistor. The gate length of at least the load transistor is increased by at least 10% compared to a gate length of transistors manufactured according to layout rules imposed by a CMOS manufacturing process, thereby increasing the light sensitivity of the pixel structure.
