Embodiments are disclosed to monitor and present biometric information for a user wearing a watch. The watch may include a biometrics sensor configured to output biometric signals associated with a user wearing the watch and a processor configured to select one of a plurality of alphanumeric characters based upon the determined biometric information. The watch may include a first disc coupled with a first motor and including the plurality of alphanumeric characters, the first disc positioned under the first window such that one of the plurality of alphanumeric characters, such as a target heart rate zone, is visible through the first window as the first motor rotates the first disc.

A method for controlling an electronic watch includes a first pointing hand, a first motor configured to move the first pointing hand, a second pointing hand, a second motor configured to move the second pointing hand, a pressure sensor configured to measure pressure, and a mode indication unit configured to indicate a mode, and when detecting start of diving based on a pressure measured by the pressure sensor, control is performed on the first motor and the second motor to indicate with the first pointing hand a water depth estimated from the pressure and indicate with the second pointing hand a time period of diving for which timing is started after detecting the start of diving, and when the water depth is indicated with the first pointing hand, with a plurality of modes with different indication resolutions being provided, the selected mode is indicated on the mode indication unit.

A method for controlling an electronic watch that includes a first pointing hand, a first motor configured to move the first pointing hand, a second pointing hand, a second motor configured to move the second pointing hand, and a pressure sensor configured to measure a pressure, the method including, when start of diving is detected based on a pressure measured by the pressure sensor, controlling the first motor and the second motor, and indicating with the first pointing hand and the second pointing hand a water depth based on the pressure and a diving time period.

An analog electronic watch includes watch's internal time, and controls rotation of a group of indicators based on the watch's internal time. A terminal appliance stops the rotation of the group of indicators, generates an image of the indicators and the dial plate with an imaging unit, detects current display positions of the group of indicators in identification areas as part of the image of the indicators and the dial plate, generates current display time information based on the current display positions, and generates display time correction information based on a difference between the current display time information and the watch's internal time information. The analog electronic watch corrects the display positions of the group of indicators based on the display time correction information. There are provided an analog electronic watch system and an analog electronic watch that can reduce a time required for display time correction.

There is provided a timepiece which includes a movable pointer, an acquisition unit which acquires information on a movable range corresponding to at least a portion of a movable range of the movable pointer and acquires information indicating a target position to which the pointer is to be moved, a control unit which compares the target position with the movable range and determines a movement direction of the pointer based on the comparison result, and a drive unit which drives the pointer in the determined movement direction.

A timepiece includes a motor control unit driving a motor for driving an indicating hand, based on an instruction signal, and a control unit receiving an instruction confirmation signal corresponding to a drive state of the motor in response to the instruction signal from the motor control unit, and determining whether or not the motor is driven in accordance with the instruction signal, based on the instruction confirmation signal.

This disclosure describes systems and methods for using a primary device, communicatively coupled to a remote system, to configure or re-configure a secondary device in the same environment as the primary device. In some instances, the primary device may communicatively couple to the secondary device via a short-range wireless connection and to the remote system via a wireless area network (WAN), a wired connection, or the like. Thus, the primary device may act as an intermediary between the secondary device and the remote system for configuring the secondary device.

An electronic timepiece can prevent overrunning when driving a motor at a high speed. The electronic timepiece has a controller that controls a driver to an on state or an off state according to the current value detected by the current detector; a polarity changer that determines driving one step of the motor ended and changes the polarity of the drive current when the on time or off time is detected to meet a specific condition; and a drive period adjuster that sets the terminal supplying the drive current to the coil to a first state if the remaining drive step count is greater than the remaining count evaluation number, and if the remaining drive step count is less than or equal to the remaining count evaluation number, sets the terminal to a second state in which the brake force applied to the rotor is greater than in the first state.

An electronic timepiece detects an external magnetic field without using a magnetic sensor. The electronic timepiece has a driver that drives a motor; a current detector that detects a current value flowing through a coil of the motor; a controller that controls the driver to the on state or the off state according to the detected current value; a polarity changer that alternately changes the polarity of the drive current to a first polarity and a second polarity when an on time, which is a continuous time of the on state, meets a specific condition; a counter that counts the number of on states in the first polarity and the number of on states in the second polarity; and an external magnetic field detector that detects an external magnetic field based on a result of comparing the counted number of on states in the first polarity and the second polarity.

A mobile device includes a drive unit for which correspondence between a command that is input and a drive signal that is output to an operation unit is predetermined, and a controller configured to output the command to the drive unit and cause the operation unit to operate. The controller includes a storage unit storing therein a user program including script language and outputs the command in accordance with the user program.
