A wearable electronic device for conveying information in an analog manner at least in part by the use of at least one display hand positioned on the dial side of a dial, wherein the wearable electronic device uses the display hand(s) to convey information that is stored in the controller of the device and/or provided by sensors and/or an external transmitter. An actuation mechanism, preferably a stepper motor, is used to rotate the display hands in the clockwise and/or counterclockwise directions in predefined increments to convey the information.

An implant device for cartilage regeneration in loading-bearing regions uses the osteochondral defect model. The implant is formed of resorbable polymeric materials. The implant is designed such that load is transmitted from the articulating surface of the bone platform through the implant to the entire area of subchondral bone of the bone platform. Application of load in this manner results in reduced subchondral bone resorption, leading to joint stabilization and maintenance of normal joint biomechanics. The implant allows for the incorporation therein of a resorbable scaffold or matrix material. The present implant solves the current inability to regenerate cartilage in load-bearing articulating surfaces using engineered scaffold devices.

An improved illuminated watch movement with analog and digital features comprising a frame containing an analog stepping motor and gear train connected to operate timepiece hands located substantially in the center of the movement. The frame has a recess on the dial side of the frame with a liquid crystal display disposed in the recess and having an indicia pattern. The liquid crystal display has a large available surface which covers the lower half of the movement up to the hour wheel, so that a variety of indicia patterns may be displayed. An electroluminescent lamp is disposed beneath said liquid crystal display. An electroluminescent dial is disposed on the dial side of the frame and has a window opening framing the indicia pattern. A circuit with actuators is connected to actuate the electroluminescent lamp and/or the electroluminescent dial. The movement further includes a printed circuit board disposed on the opposite side of the frame from the dial and having contact pads. Yieldable electrical connectors such as spring metal or conductive elastomeric members extend across the frame between the contact pads and the electroluminescent dial and lamp. The movement is adapted to fit a variety of dial shapes with window openings for framing a variety of indicia patterns without significant physical alterations.

An improved movement for an analog wristwatch of the type having a plastic frame with a peripheral wall surrounding a central wall. The central wall carries gear trains on the dial side and movement side of the wall and a stepping motor driving the gear trains to drive the watch hands. An annular printed circuit board carries discrete electronic components disposed on one side and electrically connected thereto. The peripheral wall of the frame includes coplanar mounting surfaces arranged to support the PCB and has discrete recesses surrounding the central wall which receive the discrete electronic components when the annular PCB is so supported. An annular conductive spring plate disposed on the annular PCB performs various switching functions. The spring plate and the printed circuit board are held down against the coplanar mounting surfaces, and a thin, large diameter lithium energy cell fits inside the annular members.

An improved setting mechanism for a timepiece of a known type having a frame, a gear train, a detented setting stem rotatably mounted and axially slidable in the frame and having a toothed setting pinion which is engageable and disengageable with a plurality of crown teeth arranged on one of the gear train members, the stem setting pinion being arranged on a first axis and the crown tooth gear being arranged on a second axis. The improvement comprises offsetting the first axis so that it does not intersect the second axis and skewing the crown teeth in the direction of offset so that the setting pinion engages the crown teeth from a non-radial direction to facilitate engagement on only one side of the pinion. The offset further facilitates a stem extension in a non-interfering position.

A three hand movement of the type having a frame, a stepping motor mounted in the frame, a manually actutable timesetting stem disposed in the frame and a gear train driven by the stepping motor to rotate coaxial members carrying "seconds", "minutes", and "hours" hands. An improved dual reduction gear assembly comprises a first rotatable member with a toothed wheel and a second rotatable member having first and second pinions driving the "hours" and "minutes" wheels. A timesetting gear is adapted to be clutched to the "minute wheel". A friction coupling connects the first and second rotatable members during timekeeping. During timesetting, the friction coupling slips to disengage the toothed wheel from the first and second pinions, so that the second rotatable member separately functions as a reduction gear during timesetting.
