Abstract:
The present invention relates to a drive wheel (10) for integration into a clock movement, in particular into the clock movement of wristwatches, with at least a dented section (11) by whose teeth (12) a downstream wheel (20) is rotatably drivable and at least a non-dented section (13) which has a diameter chosen in such a manner that the part-circular circumference of the drive wheel (10) in the non-dented section (13) blocks the downstream wheel (20) against rotation while the teeth (21) of the downstream wheel (20) face this section. The non-dented section (13) of the drive wheel (10) comprises at least a flexible element (14) that is arranged, seen in the direction opposite to the direction of rotation of the drive wheel (10), immediately after the dented section (11) and that comprises an elasticity essentially directed in radial direction of the drive wheel (10) for the change of the diameter of the non-dented section (13) of the drive wheel (10) in the range of the flexible element (14).

Abstract:
The present invention concerns a case for screening magnetic fields, comprising at least two parts, and more particularly a lower part (4, 5) and a bell-shaped upper part (3). These parts are of a shape such that they are able to envelop a movement (1) of a timepiece. The upper part (3), moreover, is attached in such a way that while attached to the movement, it is able to move in a plane parallel to the movement (1) while it is essentially immobile in a direction normal to this plane.
Abstract:
Passive entry sensor systems and associated sensors are disclosed. The system sensor is locatable in the handle of a door and can provide an electromagnetic radiation beam transmitted either along the length of the handle between opposite ends thereof or between the handle and the door such that the sensor can detect at least a partial interruption of the beam by a user actuating the handle. The system can include an independent optical locking switch for actuation by a user to lock the door which locking switch comprises a shutter for intercepting the beam so as to flag the sensor. The system can include a power-up switch for actuation by a user to power-up the system, back-up switches for detecting a pull on the handle, indicators for indicating system status to the user, and backlight and ground light lighting.

Abstract:
A device comprises a fuel line that carries a combustible fuel including gasoline, a first optical channel that evaluates a degree of absorption at a first wavelength spectrum of light transmitted through the combustible fuel within the fuel line, and a second optical channel that evaluates a degree of absorption at a second wavelength spectrum. The first and second wavelength spectrums consists of wavelengths of between about 800 nanometers (nm) and about 1200 nm. The device further comprises a controller configured to receive inputs from the first and second optical channels representing the degrees of absorption at the first and second wavelength spectrums, correlate the degrees of absorption with proportions of ethanol and water in the combustible fuel, and output data corresponding to the proportions of ethanol and water to a controller of a combustion engine fed with the combustible fuel.
Abstract:
Passive entry sensor systems and associated sensors are disclosed. The system sensor is arranged in the handle of a door or directly mounted to the door skin. When mounted in the handle, the sensor provides an electromagnetic radiation beam transmitted either along the length of the handle between opposite ends thereof or between the handle and the door so that the beam can be at least partially interrupted or modified by a user actuating the handle. When mounted directly to the door skin, the sensor provides an electromagnetic radiation beam transmitted between the handle and the door. The sensor system includes indicators for indicating system status to the user, back-up switches for detecting a pull on the handle, locking switches for activation by a user to lock or unlock the door and backlight and ground light lighting.
Abstract:
A referenced optical chain for measuring angle or position, using transmission by optical fibers. The device comprises a measuring head (29) receiving two light waves transported by a supply optical fiber (28); at the measuring head (29), the incident light beams are collimated (33) then intercepted by an assembly comprising a fixed diaphragm (34) and a movable filter (35) intercepting one of the two light waves; this assembly constitutes the measuring system itself; the resultant light signals are then refocussed and coupled to an optical return fiber which transports the signals toward a photodetector. The measurement is linear and the measuring chain is referenced in all of the embodiments of the invention. The device may be used in any application which requires a measurement of angle or position.
Abstract:
A keyless access sensor system for use with a keyless access control mechanism (KACM) is described for controlling the operation of a locking device. The KACM receives a signal from a sensor device for keyless access to create a first output signal before the user has begun any action on the handle in order to open the door. The first output signal is sent to a general processor, which initiates a recognition process and, after recognition of the authorized user the processor then generates an unlocking signal which unlocks the locking device before the authorized user will have fully accomplished the action of opening the door. Thus the authorized user is allowed to open the door without any specific un-ergonomic and time-consuming additional action to the simple action of actuating the handle to open the door. The second signal is generated by a device, such as a fob, card or the like, carrying a unique digital or analog identification in response to RF or IR interrogation from the general processor after it receives the output signal from the sensor device for keyless access.
