Abstract: An ultrasound imaging device includes an assembly of ultrasound transducers. The ultrasound transducers are divided into a plurality of sub-assemblies each having P ultrasound transducers. The ultrasound imaging device further includes, for each sub-assembly, K transceiver circuits and a configurable routing circuit coupling the P ultrasound transducers of the sub-assembly to the K transceiver circuits where P and K are integers greater than or equal to 2, with K smaller than P. Each sub-assembly further includes at least one mobile transducer capable of being, via the routing circuit, disconnected or connected to any one of a plurality of predefined transceiver circuits among the K transceiver circuits of the sub-assembly.

Abstract: A device for detecting an electromagnetic radiation has at least one photodetector including an organic diode and an organic photodiode formed in a same stack of semiconductor layers, the organic photodiode receiving the radiation. The photodetector further includes at least one screen which is opaque to the radiation and screens the portion of the stack corresponding to the diode.

Abstract: An ultrasonic imaging device includes a plurality of ultrasonic transducers arranged in an array of a plurality of rows and a plurality of columns, the array being divided into a plurality of sub-arrays of neighboring transducers, each including a plurality of rows and a plurality of columns, the device including, for each sub-array: a single transmit and/or receive circuit; and a combiner selector and/or splitter selector circuit configurable to couple any, alone, of the transducers of the sub-array to the transmit and/or receive circuit of the sub-array, or to simultaneously couple a plurality of the transducers of the sub-array to the transmit and/or receive circuit of the sub-array. The device further includes a control circuit adapted to individually controlling the combiner selector and/or splitter selector circuits of the different sub-arrays.
