Publication number: 20230046951Abstract: A system for assessing risks of T2DM complications includes: a data acquisition module obtaining and inputting assessment parameters of a patient with T2DM into a risk assessment module; and the risk assessment module inputting the assessment parameters into a number of risk equations and using it to calculate risk values of the complication occurring after a period of time. The risk equation for all diabetic complications (i,j) is: ra(t,i,j)=1?exp{[H(t0)?H(t1)]Ca(t,i,j)} ra(t, i, j) is the risk value for the patient to develop the complication j from the current disease i at age t. t0 is an age of one patient at a state of the disease i. t1 is an age of the patient after the period of time. t is an age between t0 and t1. H(t0) and H(t1) are hazards of the complication occurring at the age t0 and the age t1, respectively.Type: ApplicationFiled: August 3, 2022Publication date: February 16, 2023Applicants: National Chengchi University, Kaohsiung Medical University, National Health Research InstitutesInventors: Ming-Yen Lin, Jia-Sin Liu, Ping-Hsun Wu, Yi-Wen Chiu, Chih-Cheng Hsu, Shang-Jyh Hwang, Hsing Luh

Patent number: 9448053Abstract: A microwave motion sensor including a transmitting device, a signal processing device, a signal processing device, and a path switching device is disclosed. The transmitting device transmits a microwave signal to a space under detection. The receiving device receives a reflected microwave signal reflected from the space under detection. The signal processing device processes the reflected microwave signal received by the receiving device to judge whether there is a disturbance in the space under detection, wherein the signal processing device generates the microwave signal. The path switching device is coupled to the signal processing device and the transmitting device and results in different phase shifts to a plurality of transmission paths travelled by the microwave signal.Type: GrantFiled: April 19, 2013Date of Patent: September 20, 2016Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Je-Kuan Jau, Ping-Hsun Wu

Patent number: 8665098Abstract: A non-contact motion detection apparatus includes at least one reception antenna, at least one transmission antenna, a voltage-controlled oscillator (VCO) and a phase lock loop (PLL). The at least one reception antenna receives a first wireless radio frequency (RF) signal. The at least one transmission antenna transmits a second wireless RF signal to an object which reflects the second wireless RF signal into the first wireless RF signal. The VCO outputs an oscillation signal to the at least one transmission antenna. The first wireless RF signal received by the at least one reception antenna is injected to the VCO. The PLL generates a control voltage to the VCO according to the oscillation signal from the VCO and a reference frequency. Controlled by the control voltage, which represents a motion information of the object, the oscillation signal of the VCO is locked to the reference frequency.Type: GrantFiled: May 31, 2012Date of Patent: March 4, 2014Assignee: Industrial Technology Research InstituteInventors: Je-Kuan Jau, Ping-Hsun Wu
