Signal transmission apparatus and signal transmission method
According to one embodiment, a signal transmission apparatus being ac-coupled with a receiving apparatus through a digital transmission line includes a transmitting module configured to transmit a differential signal based on an encoded bit serial input signal such that a low frequency component of the differential signal to be transmitted is maintained at a constant level when the differential signal based on the encoded bit serial input signal is transmitted to the digital transmission line where the encoded bit serial input signal includes a ratio of the number of logic 1 to the number of logic 0 which is different from 5:5.. .

Communication system, transmitter, receiver, communication method, program, and communication cable
The present invention relates to providing high-speed bidirectional communication while maintaining compatibility. When an hdmi® source 71 performs bidirectional ip communication with an hdmi® sink 72 using a cec line 84 and a signal line 141, a switching control unit 121 controls a switch 133 so that, when data is transmitted, the switch 133 selects a constituent signal forming a differential signal output from a converting unit 131 and, when data is transmitted, the switch 133 selects a constituent signal forming a differential signal output from a receiver 82.

Method and device for ultrasound imaging
A method of high-resolution ultrasound imaging, in which transducers are made to emit ultrasound waves in a field of observations containing micro bubbles, by making the micro bubbles burst one by one in tandem with the emissions of ultrasound waves. At each shot j of an ultrasound wave, raw reverberated signals sj(i,t) picked up by each transducer i are recorded, and then differential signals vj(i,t) representative of variations between successive raw signals are determined, a parabolic function pj(x) is fitted to the differential signals corresponding to each shot j, and then a crest aj(x0,y0) of this function pj, corresponding to the position of the micro bubble destroyed between shots j-1 and j, is determined..

Multiple signal format output driver with configurable internal load
A multiple signal format output driver is configurable to provide a current-mode logic (cml) output signal in response to a cml value of one or more first values of the control signal. The output driver is configurable to provide a low-power, low-voltage positive emitter-coupled logic (low-power lvpecl) output signal in response to a low-power lvpecl value of the one or more first values of the control signal.
