Abstract: The method of providing a pair of contact terminals on the back side of an electroluminescent (EL) lamp, of the type which has EL material between front and back conductive layers, which are disposed on a transparent substrate. A bump of conductive material deposited on the front conductive layer is insulated from the back conductive layer for providing a contact terminal on the back of the EL lamp which is connected to the front conductive layer. A preferred embodiment includes the further steps of adding an extension which relocates the back connection to a different place on the back of the EL lamp.

Abstract: A water-resistant timepiece of the type including a crystal, a timepiece dial and movement assembly, and a long-life energy cell, which comprises a continuous case of plastic having: a first outer peripheral member adapted to receive said dial and movement assembly and the long-life energy cell, and further adapted to receive the crystal to form a water-resistant seal therewith; a thin substantially flat case back wall integral with the peripheral member to form an annular edge; and a peripheral groove located in the bottom of the peripheral member. A case back blank of substantially uniform thickness, having a substantially flat central portion and an integral peripheral side wall, and preferably made of stainless steel, cooperates with the peripheral groove of the case to integrally attach the case back blank to the case to complete a thin timepiece having improved water resistance, high mechanical and structural integrity, and an aesthetic appearance.

Abstract: An improvement in a known type of display box having two complementary separable box halves arranged to display a wristwatch, comprising a rear box half of rigid material with a bottom wall, a rear wall and two spaced triangular side walls, a watch holder supported in the rear box half and adapted to display the wristwatch, and a front box half of rigid transparent material with a top wall, a front wall and two spaced substantially flat triangular side walls and adapted to nest with the rear box half. The improvement comprises a recessed pocket in the back of the rear box half, formed by a stepped contstruction in the rear wall and bottom wall, and a slot in the top wall of the front box half, the recess and the slot being so located as to cause the slot to be aligned with the recess when the box halves are nested, whereby the open box may be supported on a peg extending through the slot into the recess so as to display the wristwatch.

Abstract: An alarm setting mechanism for an analog timepiece of the type having a minute hand, an hour hand and an alarm device responsive to switch actuations. A minute setting ring and a coaxial hour setting ring are both rotatably mounted in the timepiece and include a minute alarm marker and an hour alarm marker. Both rings have crown gears coupled to a drive pinion arranged to rotate the two rings at a ratio of 12:1 to set the hour and minute markers. This is preferably accomplished using a spur tooth gear on the minute setting ring and a Geneva drive for the hour ring. A first switch is actuated in response to passage of the hour hand contacting the hour marker and a second switch is actuated in response to passage at the minute hand in close proximity to the minute marker. The alarm setting mechanism has a separate crown which is detented in three positions.

Abstract: A combined wristwatch and radiotelephone has a portion such as a wristband which typically remains on the user's wrist, and a timekeeping and radiotelephone portion which is typically removable from the portion that remains on the wrist. The wristwatch and radiotelephone portion is reconfigurable between a relatively compact form in which it is suitable for wearing on the wrist as a wristwatch, and a more elongated form in which it is suitable for use as a hand-held radiotelephone with a microphone and speaker spaced sufficiently far apart to permit simultaneous use of those components adjacent the user's mouth and ear.

Abstract: An electroluminescent dial for an analog timepiece comprising a flexible transparent substrate, an inner layer comprising electrically conductive material adhered to the substrate, an EL layer comprising a mixture of electroluminescent material in a binder adhered to the inner layer, and an outer layer covering the electroluminescent layer comprising electrically conductive material, the substrate and the layers comprising a single flexible laminated assembly and having a hole therethrough for accommodating the rotatable stem, and includes a tab portion comprising the substrate and the inner layer extending beyond the EL and outer layers. A dial support member comprising a rigid plate substantially the size and shape of the electroluminescent dial supports the dial on one side of the frame.

Abstract: A combined wristwatch and radiotelephone has a plurality of substantially rigid segment members arranged end to end in a series with pivotable connections between each adjacent pair of members in the series. The pivotal axes of these connections are substantially parallel to the longitudinal axis of the user's wrist when the apparatus is worn on the wrist as a wristwatch. The pivotable connections allow the apparatus to be curved into a shape which fits around the user's wrist when the apparatus is to be used as a wristwatch. Alternatively, the pivotable connections allow the apparatus to form a more elongated structure suitable for use as a hand-held radiotelephone when such use is desired.

Abstract: Improvement in a multimode electronic timepiece having a display, a plurality of manually actuated actuators, including first and second actuators, and an integrated circuit programmed to keep time and to provide a current sequence of a plurality of modes for performing a plurality of timepiece functions, including at least first and second modes, said integrated circuit being programmed to permit an operator to sequentially cycle said timepiece through said plurality of modes, by selectively and repetitively actuating a first of said plurality of actuators, wherein said improvement comprises: first automatic mode selection means, including a program for said integrated circuit adapted to calculate at least first and second values respectively comprising the number of times the respective timepiece functions of said first and a second modes are performed by a timepiece operator in said current sequence, and to provide a next sequence of said plurality of modes, including said first and second modes of said cu

Abstract: A multimode electronic timepiece has a display, a case, a plurality of manually actuated actuators disposed about said case, and an integrated circuit programmed to keep time and to provide a plurality of modes for performing a plurality of timepiece functions, including a first and second modes. The integrated circuit is further programmed to permit an operator to sequentially cycle a timepiece through the plurality of modes by selectively and repetitively actuating a first actuator. The improved timepiece includes a program for the integrated circuit adapted to dispose the timepiece out of a first and second of the plurality of modes into a first and second operating instruction subroutine in response to actuation of a second actuator. The first and second operating instruction subroutine respectively comprise a first and second set of operating instructions which describe the operation of the actuators when the timepiece is respectively disposed in the first and second modes.
