  • Publication number: 20200359906
    Abstract: A biological data measurement device has patches. A patch to be mounted on the human body basically includes first and second heat insulators, first and second temperature measurement circuits, and a belt-shaped wiring film (bus wire). Therefore, the configuration is simple. For example, a thickness can be approximately several mm, and a weight can be approximately several grams. The patch is easily mounted on the human body, and is inexpensive. The patch is equipped with a selection circuit, and selectively outputs a temperature signal of a first thermometer and a temperature signal of a second thermometer at a predetermined timing. Accordingly, even in a case where the patches are mounted on a plurality of locations of the human body, the number of wires is settled by the number required for one patch. The number of wires can be significantly reduced, compared to the number of wires in the related art.

  • Patent number: 8831510
    Abstract: A near-field wireless communication circuit 10 included in a terminal 1A can perform switching between a normal mode and a near mode which has a relatively short communicable distance and a relatively high transmission rate as compared with those in the normal mode. Further, a controller 13 executes preliminary processing for starting data transmission and reception in the near mode to/from a terminal 1B serving as a communication destination between the terminals 1A and 1B by using the near-field wireless communication circuit 10 which is set to the normal mode. Further, the controller 13 determines the availability of the data transmission and reception in the near mode to/from the terminal 1B by using a measured value of communication quality which has a correlation with a communication distance to the terminal 1B as a measure of the determination.
