Provided is an electromechanical transducer to be detachably attached to an electronic device, the transducer including: first and second plates; a rotor rotating around a rotating shaft supported by the plates; a fixed substrate disposed between the plates and facing the rotor; a charged portion having sub-regions disposed on the rotor at intervals in a rotating direction thereof so as to face the fixed substrate; an opposing electrode disposed on the fixed substrate so as to face the rotor; an adjusting unit for adjusting sliding properties of the rotating shaft, the adjusting unit being provided for at least one of the plates; and a gear train coupled to the rotating shaft. The gear train transmits motive power generated by the rotor rotated by electric power of the electronic device to the electronic device or transmits motive power generated by a change in orientation of the electronic device to the rotor.

The invention provides a system for providing an indication including a meniscus mobilizer, a meniscus mobilized by at least meniscus mobilizer, and at least one fluid forming the meniscus, such that mobilization of the meniscus by the meniscus mobilize is accomplished through the use of an electro-mechanical or mechanical sub-system. The system further includes a temperature control sub-system, whereby the temperature control sub-system securitizes and optimizes a meniscus displacement velocity of the meniscus. The system further includes an element of a vehicle, such as a windshield, indicators within the cockpit of the vehicle, ship, train, motorcycle or airplane. Optionally, the element comprises a transparent glass. The indication is an indication of time or other parameter such as speed, acceleration, etc. Indication is provided by means of a fluorescent active fluid that forms the meniscus. The invention includes an ultraviolet light generator. Optionally, the ultraviolet light generator is an LED, whereby the system is not lighted in an orthogonal direction and thereby invisible to a driver of a vehicle.

A method includes receiving geo-location data collected over time period. The geo-location data is associated with a monitoring device. The method further includes receiving motion tracking data of the monitoring device. The motion tracking data is collected over time period. The method includes identifying one or more activities. The activities are identified based on inference rules that identify certain activities to have occurred when at least part of the motion tracking data is correlated to the received geo-location data. The method further includes defining a metric for one or more of the identified activities. The metric is associated to a calendar date. The method includes sending the metric to a calendar application with integration instructions. The integration instructions define the calendar date to which the metric will be added.

A timepiece includes a dial plate, and a solar battery which is disposed on a rear side of the dial plate. The dial plate is provided with grooves or ridges. The grooves or the ridges have portions where inclination angles with regard to a normal line of the dial plate are different, and due to this, light which is transmitted through the dial plate is incident from a plurality of directions with angles which are different with regard to the solar battery.

A timepiece display mechanism includes a rotating display member for displaying a magnitude other than the current time of day, or a position in a cycle. The rotating display member is integral in rotation with a snail cooperating with the beak of a striking rack included in a striking mechanism integrated in or juxtaposed with this display mechanism, to strike a numerical value characteristic of this magnitude, or respectively of this position. The display mechanism is more particularly a chronograph mechanism including a seconds snail integral with a main chronograph wheel, for counting the seconds and cooperating with a seconds rack, and a minute snail integral with a minute counter wheel for counting the minutes and cooperating with a minute rack, in order, after timing a duration, to strike the minutes and seconds of the timed duration.

A control method includes acquiring time information including a wake-up set time; acquiring a sleep state of a sleeper who is stimulated by a stimulation device; determining a change of the sleep state; causing the stimulation device to start increasing a stimulus which urges the sleeper to awake at a control start time as time before the wake-up set time by a predetermined time period; and controlling a change amount of the stimulus based on the change of the sleep state with the stimulus.
