摘要:
An electronic device that includes functionality to perform at least two functions, a first of which may be timekeeping and the other of which is at least a function other than the first function. The electronic device comprises a multilayered module comprising a frame having a frame surface; at least two physically separable printed circuit boards, the first of which includes means related to at least the timekeeping and the second of which includes means related to at least the function other than timekeeping, wherein the first printed circuit board is intermediate the frame surface and the second printed circuit board; a battery compartment dimensioned for receiving a battery, wherein the battery compartment is asymmetrically positioned within the module thus creating a region above the first printed circuit board and proximate the battery compartment; and wherein the second printed circuit board is securable within the module and in the region; wherein the functionality of the electronic device can be changed and/or modified by a removal of the second printed circuit board and a replacement with another printed circuit board having means at least in part different from and/or in addition to the means of the second printed circuit board; whereby the first printed circuit board need not be removed to provide for such additional and/or different functionality provided by the replacement printed circuit board.

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.

A date display assembly for displaying the day of the month in an electronic device, the assembly comprising a units ring and a tens disc, the units ring comprising at least one series of numerals from 0 to 9 and the tens disc comprising a series of numerals from at least 1 to 3 and optionally the numeral 0; wherein the units ring and the tens disc being positioned relative to each other so as to display in the space of a window two numerals side by side, one of which is carried by the units ring and the other of which is carried by the tens disc, wherein the units ring is divided into ten sectors or a multiple of ten sectors each separating the numerals 0 to 9, the one sector separating the numerals 9-0 having an angular extent equal to ¾ of the angular extent of the sectors separating the other numerals. In the preferred embodiment, the device is a timepiece and a wristwatch in particular.

A cannula has a flange and a body with slots extending through the entire flange and into the body. The cannula may also have a longitudinal slot extending its entire length. An obturator used with the cannula may also have a longitudinal slot extending along its length. A surgical method using these instruments includes separating lengths of suture and managing the suture by placing lengths of suture in the slots in the cannula. The cannula and obturator may be used after suture is already in place by placing the suture in the longitudinal slots and then introducing the cannula and obturator to the tissue defect site. The cannula may also be used to deliver a therapeutic implant to the tissue defect site. The instruments and method may be used in mensical surgery.

Unitary surgical devices (10) are disclosed. One group of the illustrated devices has a pair of biocompatible, bioresorbable anchors (16, 18) connected to fixed lengths suture. The anchors (16, 18) and fixed length of suture are connected to each other prior to surgery. Another group of unitary surgical devices has a pair of fixating mechanisms (15, 17) connected to a base (21) prior to surgery. The second group of illustrated devices generally includes extracellular matrix material either as part of the base (21) or supported on the base (21). The extracellular matrix material serves as tissue regenerating material. In the second group of unitary surgical devices, the fixating mechanisms illustrated generally comprise suture, anchors or pre-formed holes in the base. All of the illustrated unitary surgical devices are useful in repairing a damaged meniscus. The first group of unitary surgical devices can be used to approximate inner surfaces of a tear in the meniscus. The second group of devices can be used either as an insert to be placed between and approximated to the inner surfaces of the tear or as an insert to replace a void in the meniscus left after a menisectomy.
摘要:
A movement subassembly adapted for use in either a two hand timepiece or a three hand timepiece, the subassembly having a first set of elements common to both timepieces adapted to cooperate with a second set of components, including at least one intermediate wheel assembly to make up a three hand timepiece movement, the first set also adapted to cooperate with a third set of components, using a different wheel assembly to make a two hand timepiece. The second set components includes a seconds wheel assembly, an intermediate wheel assembly, a third wheel assembly and a once-per-second pulsing integrated circuit. The subassembly frame includes bearings for journaling all of said aforementioned wheel assemblies using a common subassembly.

In a wristwatch movement with a stepping motor with a rotor connected to drive a gear train which periodically advances the hands of the wristwatch, the stepping motor has a flat stator piece secured in a plastic movement frame. A coilcore assembly comprising a flat hook-shaped core plate having a straight core portion of uniform width with a coil inserted over the free hand of the core portion is secured to the stator so that opposite ends of the hook-shaped member overlap opposite ends the stator to complete a path for the magnetic flux. The hook-shaped coil core is placed on top of the stator during assembly and is held down by insulated clamping means such as a bridge or circuit board bolted to the frame at the time of final assembly. Preferably, the stator and coil core member are located with respect to one another by plastic studs integral with the frame extending through aligned holes in the stator and coil core. Some of the studs receive bolts which hold the clamping means to the frame.
