Abstract: A control device that communicates with a first communication device and a second communication device includes: a determination section configured to determine a position of a terminal on a basis of a first ranging result obtained from a radio wave communicated between the first communication device and the terminal and a second ranging result obtained from a radio wave communicated between the second communication device and the terminal, wherein the first communication device is disposed at a first position where it is difficult to directly receive the radio wave between a first area and a second area that are separated by a first member including material through which it is difficult for the radio wave to penetrate, and the second communication device is disposed at a second position where it is possible to directly receive the radio wave between the first area and the second area.

Abstract: A wireless communication device having a control section configured to control transmission and reception of a wireless signal by an antenna in conformity with a designated communication standard, wherein the control section controls a timing of causing the antenna to transmit a second signal in response to a first signal received by the antenna, on a basis of fixed time and delay time related to internal transfer in the wireless communication device, the fixed time being decided in advance.

Abstract: To realize more secured Authentication while convenience is secured. There is provided a communication device including a control unit configured to control a process relating to transmission or reception of a first authentication signal and a second authentication signal used for a first authentication process that is authentication between the communication device and another communication device, in which the control unit further controls a second authentication process that is authentication different from the first authentication process and starts a process relating to transmission or reception of signals used for a second authentication process that is authentication different from the first authentication process before transmission or reception of the first authentication signal.

Abstract: There is provided a communication device comprising: a control unit configured to control ranging with a wireless signal in conformity with a regulated communication standard, wherein the control unit controls output intensity of a data transmission signal that has a payload based on reception sensitivity for a plurality of ranging signals transmitted to and received from other communication devices.

Abstract: To provide a mechanism capable of matching timings at which communication is performed between devices. A communication device for performing wireless communication with another communication device, the communication device comprising: a first wireless communication unit configured to perform communication conforming to a first wireless communication standard; a second wireless communication unit configured to perform communication conforming to a second wireless communication standard; and a control unit configured to control the first wireless communication unit so that the first wireless communication unit transmits, a plurality of times, a first signal, the first signal being a signal conforming to the first wireless communication standard and being a signal including setting information that is information for setting a timing at which the second wireless communication unit performs communication.

Abstract: [Problem] To provide a so-called competitive immunological assay method capable of more uniformly immobilizing on a solid phase a substance equivalent to an antigen. [Solution] This immunological assay method measures an analyte substance in a sample by using: an equivalent substance immobilized on the solid phase during the execution of the assay, the equivalent substance being immunologically equivalent to the analyte substance; and a labeled antibody for specifically binding to the substance equivalent to the analyte substance.
