Abstract:
This watch (1) includes a case (2), a glass (3) and at least one manual control device (22), which comprises a capacitive sensor (20) with a first electrode (5) arranged on the internal face (6) of the glass (3). The selective positioning of a finger (10) of a wearer of the watch (1) on the external face of the glass (3) enables a first capacity (C.sub.d) to be formed between the first electrode (5) and earth (11) constituted by the case (2). A parasitic capacity (C.sub.p) is present between the first electrode and the case.The manual control device (22) also includes a voltage-frequency converter (22) whose oscillation frequency is determined by the first capacity (C.sub.d), when the latter is formed by the presence of the finger, in combination with the parasitic capacity (C.sub.p),
Abstract:
A driving device has a stepping motor for reciprocatively rotationally driving a decorative rotary member. A memory circuit stores a data table on the basis on which the operation timing of the stepping motor is determined. A control circuit controls the application of actuation pulses to the stepping motor on the basis of the data stored in the memory circuit. The data table is made up of numeric values representative of the inter-pulse spacing of the actuation pulses, the inter-pulse spacing being selected such that the rotational speed of the rotary decorative member varies in conformity with a sine curve or the rotation angle of the decorative rotary member varies in conformity with a secant function.
Abstract:
The invention concerns a timepiece. Such timepiece exhibits at least two selectable modes of operation, a first referred to as time and a second referred to as nontime, and it comprises at least one hours hand (h) and one minutes hand (m) capable of being independently actuated by motor means (18, 20), electronic management means (22) for said modes of operation and an external control organ capable of operating on said management means, such timepiece being characterized in that it includes visual means for signalling entry into the non-time mode of operation, such signalling means being formed by said hours (h) and minutes (m) hands acting in an automatic and systematic fashion at least, upon entry into the nontime operating mode. The invention is applicable to an electronic timepiece having an analog display.
Abstract:
A sundial-like timepiece comprising a conventional clock mechanism including a surface having a plurality of time interval markings inscribed thereon. A light source is attached to the clock mechanism and is disposed a spaced distance from the surface. The light source is moved relative to the surface by the clock mechanism on either a twelve or twenty-four hour cycle. A gnomon is disposed in such a position relative to the surface that the light source causes a shadow of the gnomon to be cast onto the surface. As the light source moves relative to the surface, the shadow moves across the time interval markings, and time can be read off the timepiece by observing the position of the shadow relative to these markings. If the light source is not functional, the time cannot be read off the timepiece.
Abstract:
A clock device utilizing a hollow housing having stackable--columnar--first, second and third stations, each having a blinking light emitting diode (LED) controllably connected to a battery through a firm-wired or hardwired circuit with: the upper hour LED being energized first in sequence to present the hour of the predetermined time of day, by flashing such LED in accordance with a control algorithm or first pulse subcode to proved a total number of flashes contained in the time of day, viz., between 1 and 12; a mid-LED being next energized in accordance with a control algorithm or second pulse subcode that is decimally based, i.e., each flash denoting the number of ten minutes blocks or decades contained in the time of day; and a lower-LED being next being energized in accordance with a control algorithm or third pulse subcode that is also decimally based, each flash denoting a number of minute units in a particular 10-minute block, such number being between zero and nine. With such LED's being energized in serial fashion with the hour station providing a traditional hour display and the minute stations providing a decimal based displays, it has been found that children can learn to tell time and to count.
Abstract:
A device for indicating time comprises means arranged to display the number of equally large time increments of a predetermined size, for instance 15 minutes, remaining until a predetermined occurrence is intended to take place.
Abstract:
A double-faced clock having a device for adjusting time difference between two clock part. The double-faced clock comprising a first clock part containing a first gear group for operating hands of clock, a second clock part attached to a rear side of the first clock part which contains a second gear group similar to the first gear group, a driving shaft rotatably supported in the first and second clock parts and driven by a driving source which is mounted with a first driving gear engaging with any gear of the first gear group at its first end and which is mounted with a second driving gear engaging with any gear of the second gear group at its second end, and means for adjusting selectively time of one or both of the first and second clock parts.
Abstract:
A double faced watch has a movement driving a first gearing actuating a first hands array cooperating with a first dial and a second dial 31 on its opposed face cooperating with a second hands array 32, 33', 43. An automatic winding mass 19 is pivoted concentrically to the two hands arrays by a bail bearing the internal housing of which is fastened on a sleeve giving passage to an axle 7, 7', carrying one hand of the first hands array. This axle 7, 7' is used as a driver for the driving of the second hands array. A time setting stem 55 is axially slidable between two positions, in one of which its rotation sets one of the hands arrays and in the other of which its rotation sets the other hands array. A tilting member 62 (FIG. 6) ensures that the setting stem 55 slides in the opposite direction from a sliding pinion 47 so that the stem 55 and pinion 47 are alternately in driving relation with one or the other of the drive trains of the two hands arrays.
Abstract:
A programmable clock includes a memory for storing times, dates and messages for subsequent read-out and display in providing a reminder of a birthday, anniversary, doctor's appointment, meeting, etc. The clock is adapted for prominent display by mounting to a wall or other support structure and provides a user with a visual display of stored reminder messages, as well as an indication of the content of the reminder message, over a given future time period, i.e., all stored reminder messages for today, tomorrow, or some other selected day in the future. The reminder clock also includes a speaker and an audio recorder for providing a reminder message in the user's own voice, as well as a printer for providing more extensive reminder messages as well as a list of all stored reminder messages. The reminder clock makes use of any one of several analog and combined analog and digital time displays which are easily read and understood, including a display presenting an analog representation of hours and a digital display of minutes. Various audio and/or video alarms are provided to indicate the read-out and display of a reminder message. An electronic pendulum is provided to indicate proper operation of the reminder clock as is a calendar indicating the days and times when stored reminder messages are to be recalled from memory and displayed.
Abstract:
Apparatus is disclosed for assistance in learning binary number notation. Various examples of the apparatus are disclosed, each example comprising symbols each of which can be switched between two states in which it is respectively visible and invisible. Further, each symbol is oriented differently to the other symbols or alternatively the apparatus is provided with other insignia which enables each symbol to be distinguished from the others without reference to the others. Similar apparatus with symbols other than visible symbols is suggested.
