Abstract:
A display control unit performs switching between internal measurement information (for example, a lap time and others) and living-body information (for example, the number of heartbeats) indicated by a living-body signal for display on a display unit, based on whether or not a receiving unit acquires the living-body signal (for example, a heartbeat signal). Accordingly, a user can switch between displaying living-body information indicated by a living-body signal on a running watch (a display unit) and not displaying the living-body information indicated by the living-body signal on the running watch, depending on whether or not a chest strap is worn. Accordingly, the user does not need to perform a user operation for switching between the display of the internal measurement information and the display of the living-body information indicated by the living-body signal. Therefore, a user's laborious job of performing a display switching operation can be reduced.
Abstract:
An object is to provide a pointer driving motor unit which can easily control driving of a pointer of a time piece by a stepping motor, a multifunctional electronic device, and a control method of a pointer driving motor unit. A pointer driving motor unit includes: a supporting body; a stepping motor which rotates a pointer that is supported to be rotatable with respect to the supporting body; a plurality of input portions which include a first input portion into which a first instruction signal is input from a main control portion, and a second input portion into which a second instruction signal is input from the main control portion; and a control portion which is provided in the supporting body, outputs a first driving signal that drives the pointer by a first operation to the stepping motor based on a result of comparing the first instruction signal and a predetermined threshold value with each other, and outputs a second driving signal that drives the pointer by a second operation to the stepping motor based on a result of comparing the second instruction signal and a predetermined threshold value with each other.
Abstract:
There are provided an electronic device, a communication system, and a method of controlling an electronic device which are capable of reducing the number of times manipulation associated with communication using a solar cell. The electronic device includes a solar cell, a secondary battery that is charged by the solar cell, and a control circuit that switches between a charging period during which the charging of the secondary battery from the solar cell is performed and a communication period during which an optical signal is received by the solar cell.
Abstract:
To perform stable communication in communication by an optical signal. An electronic device includes a display part having a light source which transmits an optical signal, a direction detection part detecting a direction of a display screen of the display part and a controller transmitting data by the optical signal from the display part to an electronic timepiece when the direction of the display screen detected by the detection part becomes a predetermined direction.
Abstract:
A time interval setting unit sets a time interval that depends on the number of items of data stored by a storage unit. A storage processing unit stores the data in the storage unit at every time interval that is set by the time interval setting unit. The storage unit retains the data at the time interval that depends on data acquirement time. A data extraction unit extracts the data by the number of items of data that depends on the number of items of display data, from the items of data stored by the storage unit. When the time interval setting unit updates the time interval, it is not necessary to perform subsampling or compression on the data stored by the storage unit and the data can be retained at the time interval that depends on the data acquirement time with less processing load.
