Publication number: 20240115182Abstract: An electrocardiogram measurement unit comprises: a pair of positive and negative electrode bodies and constituting capacitive coupling electrodes and arranged in a non-contact state with a human body; a signal amplification unit that amplifies an electric signal from both the electrode bodies and outputs the amplified electric signal as an electrocardiographic signal; and an inverting output unit that inverts an in-phase signal of the electric signal from both the electrode bodies and outputs an inverted signal. The electrocardiographic signal measurement device comprises simultaneously both channels and when the electrocardiogram measurement unit to which the inverted signal from the inverting output unit is input to the positive electrode body is defined as a first channel, and the electrocardiogram measurement unit to which the inverted signal from the inverting output unit is input to the negative electrode body is defined as a second channel.Type: ApplicationFiled: February 17, 2022Publication date: April 11, 2024Inventors: Satoshi MATSUNUMA, Ayako SHINTANI, Kazuaki SHIMADA, Reiji HATTORI

Publication number: 20170094067Abstract: A data communication control device includes a transmitting unit that transmits data; and a receiving unit that receives the data through a communication line. The transmitting unit includes a transmitting component that transmits an establishment signal of establishing communication to transmit the data to the receiving unit, and a first controller that controls the transmitting component. The receiving unit includes a receiving component that receives the data transmitted by the transmitting component, and outputs a confirmation signal of confirming the establishment of the data communication with the transmitting component when receiving the establishment signal, and a second controller that controls the receiving component, and transmits a notification signal of notifying the first controller about the establishment of the data communication through a dedicated line different from the communication line when receiving the confirmation signal.Type: ApplicationFiled: February 8, 2016Publication date: March 30, 2017Applicant: FUJI XEROX CO., LTD.Inventors: Yujin ISHI, Kazuaki SHINTANI
