Abstract:
Disclosed are an optical spectroscopy system using a matched filter-based broadband signal receiver for stable data extraction, and a method for controlling the optical spectroscopy system. The optical spectroscopy system may comprise: a light transmission unit for irradiating light on a particular region of a subject by means of a plurality of light sources, wherein the light irradiated from the plurality of light sources is code-modulated by means of the Walsh codes and then irradiated; and a light receiving unit for detecting emergent light which has passed through the particular region, wherein the light source is identified by demodulating the light by means of the Walsh codes.
Abstract:
A wireless electric power receiver (850) for receiving wireless electric power from a wireless electric transmitter (800) is provided. The wireless electric power receiver includes an electric power receiving unit that receives wireless electric power from the wireless electric power transmitter; a rectifying unit (860) that rectifies wireless electric power in the form of alternating current output from the wireless electric power receiving unit (870) and outputs rectified electric power; and an electric power regulation unit that receives an input of the rectified electric power, outputs first electric power which has a lower value of a first voltage than that of the rectified electric power for a first period, and does not output electric power for a second period, so as to output electric power with a predetermined voltage value.
Abstract:
A method and apparatus for relocation of a mobile robot is provided. The relocation method includes the steps of generating a fingerprint based on a previously built magnetic field map, and if the mobile robot is determined as being failed in localization, relocating a location of the mobile robot based on the generated location fingerprint. The step of generating the location fingerprint includes the step of generating the location fingerprint based on the magnetic field map and location measurement values for the mobile robot that are previously measured by a radio source.
Abstract:
A magnetic resonance imaging MRI) apparatus, including a signal transceiver; a controller configured to control the signal transceiver to apply a bipolar gradient magnetic field in an aortic direction, the aortic direction being a direction in which an aorta is disposed within an object; and an image processor configured to receive, from the signal transceiver, phase signal data obtained by applying the bipolar gradient magnetic field to the object, acquire motion data representing a first motion corresponding to a heartbeat of the object and a second motion corresponding to a respiration of the object based on the phase signal data, and acquire MRI data based on the motion data.
Abstract:
The present invention relates to a thermoelectric device and a manufacturing method thereof, and a thermoelectric material is formed on a mesh type substrate made of a glass fabric, and the like. According to the present invention, since the thermoelectric material is supported by a substrate without a substrate made of alumina, and the like, the thermoelectric device has a light weight and thermal loss is minimized by the substrate to maximize thermoelectric efficiency.
