A measurement apparatus according to the present disclosure including a plurality of transparent electrodes provided on a surface of a display, an acquisition part acquiring an imaging signal obtained by imaging the surface of the display from an inside of the display, a configuring part configuring electrode pair candidates from the plurality of transparent electrodes based on the imaging signal acquired in a state that a subject touches the surface of the display, an electrocardiographic waveform signal measurement part measuring electrocardiographic waveform signals of the subject using respective electrode pair candidates configured, and a determination part determining a measurement electrode pair from the electrode pair candidates based on the electrocardiographic waveform signals measured using respective electrode pair candidates. This measurement apparatus is applicable to, for example, performing a personal authentication process of the subject based on the electrocardiographic waveform signal.

Measurement apparatus, measurement method, program and information processing apparatus

There is provided an information processing apparatus including a data encoding unit that generates an encoded signal by encoding first input data based on CMI (Coded Mark Inversion) coding rules and encoding second input data using errors of the CMI coding rules, a clock signal addition unit that generates a transmission signal by synchronously adding a clock signal having an amplitude value larger than that of the encoded signal to the encoded signal generated by the data encoding unit, and a signal transmission unit that transmits the transmission signal generated by the clock signal addition unit.

Information processing apparatus, encoding method and signal transmission method

A signal processor, which includes: a signal receiving section for receiving signals encoded under a predetermined code rule; a rule violation detecting section for detecting code rule violation included in the signals received by the signal receiving section; an error range specifying section for specifying a range in which an error bit is included out of a bit string which constitutes the signals on the basis of a position of the code rule violation detected by the rule violation detecting section; and an error correcting section for correcting one error bit in the range specified by the error range specifying section so that the code rule violation detected by the rule violation detecting section is eliminated.

Signal processor and error correction process

A sleep length calculation unitof a terminal calculates a sleep length based on what is contained in a PLCP header of a frame, and sets the calculated length on a timer. An address detection unitof the terminal detects a destination address from inside a MAC header of the frame to see if this frame is destined for another terminal. If the frame is found destined for another terminal, then this terminal gives a power supply unitan instruction to start sleeping while causing the timerto start counting time. When the sleep length is found to have elapsed on the timer, the terminal gives the power supply unitan instruction to stop sleeping. If what is contained in the PLCP header or MAC header is not deemed reliable, then a sleep inhibit determination unitinhibits the power supply unitfrom going to sleep. The structure allows a wireless communication system to effect a transition into power-saving mode upon acquiring necessary information, without making changes to existing standards.
