Patent number: 11006855Abstract: An ultrasonic receiver receives ultrasonic waves reflected at a plurality of portions of the body of a person to be measured, and thus the person to be measured needs to input the approximate height of himself/herself. An electrostatic capacitance sensor includes a transmission electrode and a reception electrode. The electrostatic capacitance sensor measures a mutual capacitance between the transmission electrode and the reception electrode by a mutual capacitance method. A variable frequency pulse generator generates a pulse supplied to the transmission electrode. A control apparatus allows the variable frequency pulse generator to sweep the frequency of the pulse and allows the electrostatic capacitance sensor to measure the mutual capacitance to identify a frequency at which the measured mutual capacitance is minimized. The control apparatus obtains the height of a person to be measured on the basis of the identified frequency.Type: GrantFiled: May 3, 2018Date of Patent: May 18, 2021Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Kakeru Kimura, Masahito Kajiwara, Shinji Takeda, Takuro Ichikawa, Shoichi Hamada, Koji Hirano

Publication number: 20190341151Abstract: A health support system that facilitates estimation of a user's health condition status and improvement of the health condition status is constructed. The health support system includes a first sensing device for acquiring biometric information of a user, a first actuator device operating based on abstracted data, and a first server connected to the first sensing device and the first actuator device via a network in a daily living space in which the user lives a daily life. The first sensing device or the server generates the abstracted data based on the biometric information. The abstracted data is classified by estimating a health condition of the user. The first actuator device facilitates improving a health condition of the user.Type: ApplicationFiled: April 10, 2019Publication date: November 7, 2019Inventors: Shoichi HAMADA, Kakeru KIMURA, Hirohisa IMAMURA, Koji HIRANO

Patent number: 8981975Abstract: In AD conversion of a voltage, data continuity is ensured between the results of conversion after amplification and of direct conversion without amplification. In AD conversion operation, an analog signal output from a DA converter circuit is directly converted by an AD converter circuit, and the analog signal is converted after amplification with an expected gain of 2?. Based on resultant data, a gain of an amplifier circuit and an offset thereof are calculated. An analog signal to be enhanced in bit precision is amplified by the amplifier circuit and converted by the AD converter circuit, the offset is subtracted from the resultant conversion, and the result is multiplied by a ratio of the expected gain to the calculated gain to cancel gain error. Based on data with gain error canceled, acquisition of bit-extended conversion result data is performed to ensure continuity between data having different degrees of bit precision.Type: GrantFiled: December 3, 2013Date of Patent: March 17, 2015Assignee: Renesas Electronics CorporationInventors: Yoshimi Iso, Kakeru Kimura, Tadashi Matsushima, Yuji Shimizu
