A method of recovering and restoring the voltage in a zinc-air battery that has dropped below a first threshold. The method includes the steps of decoupling essentially all loads from the zinc-air battery and permitting the voltage to stabilize, sampling the voltage to determine if the voltage of the zinc-air battery is below a second predefined threshold, starting a timer and determining if the voltage has recovered to at least a third predefined threshold prior to the timing out of the timer, ...

A carrier for a wrist instrument when it is removed from the wrist band comprises a case made in two pieces of identical construction which slide together and house the wrist instrument and its attachments. The two carrier sections each have a tongue extending across a parting line which is received in a mating channel on the other carrier section. Additional guide pins and recesses hold the assembly in alignment. A holster for the assembled carrier sections cradles the assembly securely and inc...

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...

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 step...

An electronic timepiece having a universal, wireless controller for transmitting wireless signals that control features of a plurality of systems. In a first aspect of the present invention, the electronic timepiece includes a data store which contains a library of control signals. In one embodiment, the library of control signals may be detached from the electronic timepiece so that new control signals may be added to the library. Each of the control signals can be retrieved and transmitted by ...

A removable link for use in an arrangement comprising a plurality of interlocking links is provided. In a preferred embodiment, the removable link is used in a watchband and preferably comprises a link body having a first end and a second end; a hand portion having a bar receiving region formed at the first end of the body; a bar coupled to the second end of the body, for coupling to the decoupling link; a retractable retaining pin having a first end within the link body and a second end extendi...

A display box for a consumer article is presented that includes a base, a support member and a cover. The base has at least one platform that includes an outer surface, a bottom surface, and a flange extending from the at least one platform. The base further includes an opening in the bottom surface defined by edges of the flange. The support member is adapted for supporting the consumer article and has a pedestal that is selectively mountable on and decoupleable from the flange. The cover has a...

A wristwatch dial illumination system with a light guide beneath a light transmissive dial receiving light from an LED mounted on a PC board below the light guide. A pattern of white reflective dots on the bottom surface,of the light guide selectively ejects internally reflected light toward the dial and an absorption pattern of light absorbing material selectively absorbs ejected light, including the bright spot from the LED.

A multimode electronic timepiece includes a display, an audible alarm device, a plurality of manually actuated switches, and an integrated circuit programmed to keep time and to provide a plurality of modes including time-of-day, alternate time zone and alarm setting modes. The integrated circuit is programmed to permit an operator to set time-of-day in response to actuation of selected switches, to set alternate time zone time in response to actuation of selected switches, and to set alarm set ...
