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.

An adjustable timer useful to isolate a household solar array together with its power storage elements from the utility grid power connected to the household in order to fully accumulate the power stored in the storage elements that are then available for use at a time when the household occupants return to the household. One such use of the power thus stored may be to recharge an electric vehicle and other uses may include energy storage mechanisms utilizing compressed refrigerant.

A watch including an electronic movement driving display for an analog display on a dial of at least one additional function in addition to a normal current time display, the at least one function being controlled by a controller and including at least one phase using an operating mode in which a duration of the phase is measured.

A force sensor including: a first part including a detection coil; a second part positioned opposite the first part and including: a ferromagnetic plate translationally movable relative to the first part to move towards the first part when a force is transferred to the sensor and to reduce reluctance of a magnetic circuit formed by the first and second parts in series with a variable gap; and an electronic detection circuit configured to generate a signal dependent on the reluctance of the magnetic circuit. The ferromagnetic plate is formed by an amorphous metal alloy.

An apparatus and a method for controlling a vehicle may include at least two buttons provided on a steering wheel, a processor electrically connected to the at least two buttons, and storage that stores instructions executed by the processor, wherein the processor may map and set a vehicle function to the at least two buttons, detect a button manipulated among the at least two buttons, and perform a vehicle function mapped to the manipulated button based on the vehicle function mapped to the operated button and a current vehicle state.

Systems and methods for operating a communication device. The methods comprise: monitoring, by the processor, states of snap-dome based switches of a keypad provided with the communication device; activating, by the processor, a first timer when the snap-dome based switches are simultaneously activated; detecting, by the processor, when maintenance of the communication device is needed based on a value of the first timer; and causing, by the processor, performance of communication device maintenance based on the detecting, for immersion time and immersion depth fatigue.
