  • Patent number: 11994438
    Abstract: A communication device of an embodiment includes a normal operation mode and a low-power consumption mode and includes a first memory unit, a second memory unit, and a control unit. The first memory unit includes a work area for execution of firmware configured to perform basic control of the communication device. The second memory unit stores software for communication with an external device. When transition is performed from the normal operation mode to the low-power consumption mode, the control unit stops voltage supply to the first memory unit and performs control to reduce voltage supplied to the second memory unit to lower than a voltage in the normal operation mode.
    Type: Grant

  • Publication number: 20210243581
    Abstract: A wireless device includes a clock for generating clock cycles, a wireless transmission/reception circuit, a counter configured to count the number of clock cycles output by the clock since a previous point in time, and a controller. The controller is configured to append a first counter value from the counter to transmission data. The first counter value corresponds to a time of transmission for the transmission data from the wireless transmission/reception circuit. The transmission data further includes a measurement value from a sensor device and a second counter value from the counter corresponding to a time of measurement for the measurement value.
