Abstract:
Disclosed herein are an apparatus and method for controlling smart wear. The apparatus for controlling smart wear includes a motion capture unit, an error information unit, a motion estimation unit, and an actuation unit. The motion capture unit captures a motion of a user using sensors included in the smart wear. Then error information unit generates user error information using reference motion information and the results of the motion capture. The motion estimation unit estimates a subsequent motion of the user using the user error information. The actuation unit controls the smart wear of the user in real time using the estimated subsequent motion and the user error information.
Abstract:
An apparatus and method for transmitting data using a human body. The apparatus includes a parallel bit stream generation unit, a frequency selective spreading unit, a matched filter unit, and a transmission filter unit. The parallel bit stream generation unit outputs a parallel bit stream for an input serial bit stream. The frequency selective spreading unit divides the parallel bit stream into a preset number of bit groups, generates a single code vector by combining orthogonal code vectors corresponding to the respective bit groups, and shifts the center frequency of a transmission signal by spreading the single code vector using a frequency shift code. The transmission filter unit meets a transmit mask for the transmission signal.
Abstract:
The present disclosure relates to a capsule endoscope transmitter configured to transmit frames including control frames and data frames to a capsule endoscope receiver. The capsule endoscope transmitter includes a preamble generator configured to generate preambles for synchronizing and identifying the control frames used to select a reception electrode pair that receives the frames, and a line sync generator configured to generate a line sync for synchronizing the data frames and identifying a code value of each of the data frames.
Abstract:
Disclosed herein are a wearable wireless power transmission apparatus and a wearable wireless power transmission using the same. The apparatus includes a wearable energy harvesting unit, a wearable battery unit, a wearable power charging unit, a wearable power transmission processing unit, and a fiber-type primary coil unit. The wearable energy harvesting unit generates power from at least one of light energy and kinetic energy, and is attachable to fabric. The wearable battery unit stores the power, and is attachable and detachable to and from the fabric. The wearable power charging unit rectifies the power, charges the wearable battery unit, and is attachable and detachable to and from the fabric. The wearable power transmission processing unit generates a transmission signal, and is attachable and detachable to and from the fabric. The fiber-type primary coil unit wirelessly transmits the transmission signal to the secondary coil unit of the power reception terminal.
Abstract:
Provided is a capsule endoscope. The capsule endoscope includes: an imaging device configured to perform imaging on a digestive tract in vivo to generate an image; an artificial neural network configured to determine whether there is a lesion area in the image; and a transmitter configured to transmit the image based on a determination result of the artificial neural network.
Abstract:
Disclosed are an electric power conversion apparatus and method in an energy harvesting system. In more detail, it is possible to obtain the maximum electric power from the plurality of energy sources by selecting the connection structure between the source terminals or the connection structure between the source terminals and the collection terminals using the electrical characteristic values (for example, open voltage, short current, and internal impedance) of each source and adjusting the load impedance in the selected connection structure in the energy harvesting system.
