This disclosure provides a system (100) for determining patient (P) movement for a medical imaging system, comprising at least one marker (110), and at least one data processing unit (120), wherein the marker (110) is a solid configured to be swallowed by the patient (P). The marker (110) comprises a landmark forming component (111) configured to be detectable within the patient during a medical imaging procedure to determine the movement of the patient. The at least one data processing unit (120) is configured to obtain patient information data and/or medical imaging information data at least indicative for a type of medical imaging procedure intended for the patient. The at least one data processing unit (120) utilizes a computational model to estimate, based on one or more of the patient information data, the medical imaging information data and a configuration of the at least one marker, a position and/or distribution of the at least one marker inside the patient to a certain time and/or over a period of time after swallowing by the patient (P). The data processing unit (120) is configured to generate, based on the estimation of a distribution of the at least one marker, control data for timely controlling the medical imaging procedure.

An operating method of an electronic apparatus, which is performed using a UWB communication module including a plurality of antennas, includes emitting a UWB transmission signal, receiving a UWB reflection signal reflected from an object, and obtaining three-dimensional information of the object based on the UWB transmission signal and the UWB reflection signal, wherein the plurality of antennas are respectively arranged in a vertical direction and a horizontal direction on a front surface of a display of the electronic apparatus.

A sleep monitoring system includes an ECG device (2) and a respiration inductance plethysmogram (3) which monitor cardiac activity and physical (ribcage) respiration respectively and feed representative signals to a digital data processor. Operations (5-9) process the beat interval data, while in a second thread, operations (20-24) independently process the amplitude modulation of the ECG data caused by the respiratory motion of the subject. The inductance plethysmogram device (3) provides an input to the processor which represents respiration as directly monitored independently of the ECG. Operations (30-34) process this direct respiration data independently and in parallel, in a third thread. All extracted features are fed to a classifier which in step (10) combines selected combinations of features to make decisions in real time.

An energy harvesting device includes a housing (2), a moveable device (12) disposed within the housing and including a first surface including a first material (15) and a second surface including a second material (17), wherein the moveable device is operable to move to bring the first and second surfaces together and apart to cause contact and separation between the first and second materials, a first strap (4) attached to the housing, a second strap (6) coupled to the moveable device, wherein movement of the second strap causes operation of the moveable device, and electronic circuitry (20) structured to harvest energy from the electrical charge generated by the contact between the first and second materials.

This disclosure generally relates to systems and methods for video detection of breathing rates in a subject, such as a sleeping baby. One or more video cameras may capture video of the subject. The video may be corrected and then a featured signal may be generated from the corrected video. A respiratory rate detector may be built to output a signal that represents breathing of the subject in the video. The signal may be corrected for any double detections. A breathing rate of the subject may be determined, and then the breathing rate of the subject may be output. In some examples, if the breathing rate is determined to be abnormal, an alarm or notification of the abnormality may be generated, or a moving platform on or in which the subject is sleeping may be moved.

A method for correcting magnetic resonance (MR) object movements includes performing a recording of an MR object with multiple echo trains. k-space data pertaining to an echo train regarded as impaired by an MR object movement is corrected by linking the k-space data to corresponding k-space data reconstructed from k-space data of other echo trains by a PPA method.
