Abstract:
An electronic alarm wristwatch including a wristwatch case with a time display and an alarm buzzer therein wherein the display overlaps at least a portion of the alarm buzzer is provided. The alarm buzzer is positioned in a sound member in registration with buzzer openings in the watchcase for directing the buzzer sound to the time display side of the wristwatch. By overlapping the time display and buzzer, the size of the time display area may be increased without increasing the overall size of the wristwatch.
Abstract:
Mechanism for controlling the function of an analogue watch permitting the display of the state of at least one of the functions.It comprises a disc 16 for displaying the states; a lever 8 articulated to the pull-out piece 6 and on which a push button 18 acts; a pawl 10 articulated at the end of the lever 8; a wheel 12 meshing with the wheel 14 which bears the disc 16. For one position of the pull-out piece 6, the push button 18 moves the lever 8 in such manner that the pawl 10 causes the rotation of the wheel 12 and of the indicator 16. For the other positions, the push button 18 has no effect.
Abstract:
A digital wristwatch including a transmitter therein for selective activation of a remote electronic circuit by the wearer. The digital wristwatch includes a time-of-day readout encased in a housing supported by a wrist band. Within the watch housing, the following elements are provided: (1) a digital clock circuit for controlling the time-of-day display, (2) a signal transmitter which is operatively, electrically connected to the digital clock circuit, and (3) a battery for operation of both the digital clock circuit and the signal transmitter. The signal transmitter may be activated by one of two methods: (1) a pushbutton switch on the side of the watch housing or (2) by an externally-supplied, electrical signal to terminals on the watch housing. The pushbutton switch extends outwardly from the housing of the watch to enable the wearer to activate the transmitter in a manner which is undetectable to the observer. The terminals, one located under each of the two wristband attachment arms, is used to activate the transmitter from an external device. An example of such an external device would be a pulse rate detector and comparator built into the wristband. The wearer's pulse rate could be monitored and if it exceeded predetermined limits, the signal transmitter would be activated. A receiving station is provided remotely from the wristwatch and is adapted to receive the transmitted signal from the watch to activate an electronic circuit such as a burgler alarm, fire alarm, medical alert, door opener, etc.
Abstract:
An alarm wrist watch incorporating a watch band, a watch casing and an electro-acoustical signal transmitter which can be activated by the watch movement or clockwork at pre-selected signalling times. The electro-acoustical signal transmitter is arranged at a part of the watch band removed from the watch case.
Abstract:
A horological instrument includes a source of electrical energy and an electrical audible alarm. The circuit between the energy source and the alarm is normally open. A setting stem rotates a geared disc. The disc carries a conductive track and a conductive contact point. The contact point, normally twice a day, contacts a portion of the hour wheel, closing the circuit and allowing the alarm to sound.
Abstract:
The alarm wheel (5) is mounted with axial clearance between an insulating plate (6) and a wheel (8).This wheel (5) is in mesh with the hour cannon wheel (3). It has an embossment (5a) which, once during each turn, passes in front of a magnet (9) carried by the plate (6). The wheel (5) is then attracted axially and its embossment (5a) enters into contact with the magnet (9), grounding the latter. Now, the magnet (9) being in permanent contact with one of the conductive tracks (13) of the printed circuit of the watch, this track (13) is thus grounded. The user of the watch can alter the time at which the releases are produced by altering the angular position of the plate (6). No spring acts axially on the alarm wheel (5) which moves freely between the wheel (8) and an annular rib (6e) provided on the plate 6.
Abstract:
An electronic wristwatch case construction in which a sound-emitting cover has a battery replacement hole and a plurality of sound-emitting holes. A fixing ring is disposed in concentric relationship with respect to the battery replacement hole of the sound-emitting cover, and a vibrating plate cooperating with a piezoelectric vibrating element for an alarm is spaced from the sound-emitting cover. A battery hatch is detachably fastened to the fixing ring, and a sealing ring is disposed between the battery hatch and the fixing ring to provide a water-tight sealing therebetween.
Abstract:
A switching system for an electronic timepiece has: a plurality of display sections which are individually activated in response to movement of manual member for effecting an amendment of said display sections. A switching mechanism is operated by axial movement and rotational movement of said manual member for effecting the desired amendment.
Abstract:
An extremely small time-setting switch adapted for mounting in a hole in the case of an electric or electronic wrist watch. The switch is provided with a coin slot whereby it may be rotated to any one of a plurality of operating positions including a run position, a stop position, a minutes change position, and an hours change position. The switch is provided with a construction affording an extremely thin, flat package that has a stainless steel, sealed exterior surface. Terminals extend out through the bottom of the base and are formed to make the required connections to the electronic circuit upon mounting of the switch in the watch case. Contact configurations are provided that reduce the height of the switch to a minimum while affording adequate contact pressure.
Abstract:
A small alarm timepiece having a timepiece movement, an electrically operating buzzer as an acoustic alarm signal delivery means, a battery detachably mounted on the timepiece movement for energizing said buzzer for its operation, and an alarm switch for on-off control of the operation of the buzzer. This alarm switch is operatively connected with the movement so as to be closed at a preset time point and to remain closed for a certain predetermined operation period. The drive circuit for the buzzer is designed as a free-running oscillator having an oscillator transistor. In addition to the alarm switch, there is provided a switching transistor operatively connected with the first mentioned transistor. There is provided a CR-time limiting circuit operatively connected with the switching transistor for control thereof. In this way, the operating period of the buzzer is limited to only a small fraction of the closure period of the alarm switch which is adapted for being mechanically closed at the preset time by the action of an alarm control mechanism fitted to the timepiece movement. In this way, the power consumption of the electronic alarm can be minimized.
