摘要:
The invention relates to watches, generally wristwatches, whose cases incorporate electronic modules for storing information that comprise an integrated circuit connected to an antenna consisting of a coil and are able to communicate by radio signals with a reading and/or writing device adapted at least to read the information contained in a memory of the integrated circuit and often also adapted to delete or modify at least some of that information and to add other information.To eliminate the drawbacks of prior art watches in which the module is inside the case (complicated fabrication or new design of the watch, increased volume thereof) or to reduce the importance of those drawbacks (attenuation and/or distortion of the signals sent and received by the coil), in the watch of the invention the electronic module (14) is housed at least for the most part in a cavity (13) in the back (3) of the case (1) open towards the outside.
摘要:
The watch with a metallic case including an electronic module for storing data, which is mounted in an external cavity in the back cover of a case. The module can communicate via broadcast signals with a read and/or write apparatus for said data. The module includes a base on which are mounted an integrated circuit chip having at least two bumps and a coil acting as a transmission and/or reception antenna. The coil is formed by an electrically conductive wire having two ends respectively connected to said bumps of said integrated circuit chip. The coil surrounds a space in which said chip is placed. The dome-shaped base of the electronic module is a metallic element that conducts magnetic flux to insulate the module coil magnetically from the metallic case during data communication between a read/write apparatus and said module. The base of the module can be covered by a protective cover.
摘要:
A quickly resettable timer is claimed which comprises a container having a base end and a reset end; a quantity of a flowing, particulate solid medium; a funnel-like receptacle having a loading orifice nearest the reset end and a metered orifice nearest the base end, the receptacle being mounted to and spaced from the interior wall sections of the container such that the particulate medium in the base end will flow over and around the receptacle and into the reset end upon inversion of the timer by rotation in any direction; and a ring fitted snugly against each interior wall section of the container intermediate the receptacle and the reset end, the ring having an aperture positioned above and sized smaller than the loading orifice of the receptacle. Preferably, the ring has inwardly protruding sides which taper toward each other to define the aperture. Most preferably, the receptacle and at least a portion of the container are made from a substantially transparent material.
