Abstract: A dynamic vision sensor (DVS) including a plurality of substrates electrically connected to one another and stacked vertically includes a photoelectric conversion device configured to generate charges in response to incident light from an external environment that is external to the DVS sensor, a bipolar junction transistor (BJT) device including a base connected to the photoelectric conversion device and configured to output a current based on amplifying a current output from the photoelectric conversion device, and a DVS pixel circuit that detects a change in intensity of the incident light and to output an event signal based on the current. The photoelectric conversion device is on a first substrate among the plurality of substrates. At least part of the DVS pixel circuit is on a different substrate from the first substrate among the plurality of substrates.

Abstract: A wearable device includes a case, a bio-processor embedded in the case, and a plurality of electrodes connected to the bio-processor. The bio-processor is configured to selectively and respectively operate the electrodes as sensing electrodes and sourcing electrodes in response to a selection signal. The selected one/ones of the electrodes operated as sensing electrodes which pick up a biological signal from (e.g. biological activity or a biological condition of) the wearer. The selected one/ones of the electrodes operated as sourcing electrodes supply current to the wearer regulated to cause the desired biological signal to be picked up by the sensing electrode(s).

Abstract: An electrode assembly for measuring bio-signals includes a body, a fastening member extending from the body and provided on one side of the body, the fastening member including a spring groove formed therein and an aperture penetrating therethrough, and a spring inserted into the spring groove. The aperture receives a fastening stud of a patch which is supplied from outside. The spring compresses the fastening stud received in the aperture such that the fastening member fixes the fastening stud thereto.

Abstract: An apparatus for measuring bioelectrical signals is provided. The apparatus includes a sensor electrode, a sensor support, and a main body. The sensor electrode has a tapering portion that narrows toward one end and a protruding portion that extends from the one end of the tapering portion, contacts a body part, and senses bioelectrical signals. The sensor support maintains the contact between the sensor electrode and the body part. The main body is connected to the sensor support and is wearable on a living body.

Abstract: An apparatus is configured to perform a method for scrolling a display screen to correspond to a touch input in a mobile terminal. Upon detecting a touch input, the mobile terminal determines an actual coordinate value of the detected touch input, obtains a predicted coordinate value for the determined actual coordinate value, obtains a smoothed coordinate value by performing a smoothing operation on the obtained predicted coordinate value, and determines that the detected touch input has occurred at the obtained smoothed coordinate value.

Abstract: Disclosed are a brainwave sensor unit and a brainwave measurement apparatus using the same. The brainwave sensor unit includes first and second contact electrodes located on a supporter, the first contact electrode obtains a brainwave signal from a living body, and the second contact electrode is spaced apart and electrically insulated from the first contact electrode and is grounded.
