Abstract: A time of flight (TOF) camera device and a method of operating the same is provided. The time of flight (TOF) camera device includes a pulse generator configured to generate a pulse signal, a light module configured to emit output light to at least one object in response to the pulse signal, a three-dimensional (3D) sensor configured to receive reflected light when the output light is reflected by the at least one object for a first frame, a distance calculator configured to receive an output of the 3D sensor and generate a distance data signal, and a light density control device configured to receive the distance data signal from the distance calculator and output a light density control signal. The light density control signal may adjust the size of an opening in the light module to change a projected area from the output light onto the at least one object.

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).
