Abstract:
An apparatus (100) and method for monitoring an audio circuit while the audio circuit is simultaneously generating an audio signal. Specifically, an AC audio signal and DC current source supervision signal are superimposed over a speaker circuit. These signals are superimposed at the junction (145) where a first DC filter (14) and a first AC filter (130) are connected.
Abstract:
The bottom plate for a timepiece movement has a transparent or translucent first, outer part (1) that has a central opening (1.2) and at least one cutout that allows an element of a movement to pass, and also a second, central part (2) designed to carry all the members, elements, bridges, gear-trains and mobiles of a timepiece movement made of an opaque material. At least one part of the outer perimeter (2.1) of the second, central part (2) has a shape and dimensions that correspond to the shape and the dimensions of the inner perimeter (1.3) of the central opening (1.2) in the first, outer part (1). The first, outer part (1) and the second, central part (2) form a one-piece assembly.
Abstract:
La platine de mouvement d'horlogerie comporte une première pièce extérieure (1 ) transparente ou translucide comportant une ouverture centrale (1.2) et au moins un évidement donnant passage à un élément d'un mouvement ainsi qu'une seconde pièce centrale (2) agencée pour porter tous les organes, éléments, ponts, rouages et mobiles d'un mouvement d'horlogerie en un matériau opaque. Au moins une partie du pourtour extérieur (2.1 ) de la seconde pièce centrale (2) présente une forme et des dimensions correspondant à la forme et aux dimensions du pourtour interne (1.3) de l'ouverture centrale (1.2) de la première pièce extérieure (1 ). La première pièce extérieure (1 ) et la seconde pièce centrale (2) forment un ensemble d'un seul tenant.
Abstract:
A clockspring connector is provided comprising a housing (10) defining a chamber, including a carrier member (30) having a first roller (31) associated with a first turned-back loop of a first flat conductor cable (41) and a second roller (32) associated with a second turned-back loop of a second flat conductor cable (42) wherein said first and second flat conductor cables are alternatingly coiled at an inner diameter of the chamber adjacent the hub or along said outer diameter of the chamber adjacent the housing wall. The clockspring connector includes a compliant roller member (131) providing compression forces against the flat ribbon cable during rotation of the clockspring connector.
Abstract:
An improved push-button assembly for an electronic wrist instrument requires only two components, a push-button member (40) and a gasket (50) which dually functions as a spring, thereby reducing the cost of manufacturing and easing assembly. The push-button member includes a tapered end on the stem end (40b) which is temporarily deformed during assembly and retains the push-button by interference with an annular ledge (43) on the case (20).
