20100079154	CAPACITIVE ANGLE ENCODER AND WITHDRAWABLE FEEDER FOR CIRCUIT BOARD COMPONENT INSERTION MACHINES - The invention relates to a capacitive angle encoder for detecting a rotational position of a rotatable object relative to a stationary object as well as a withdrawable feeder for circuit board component insertion machines, said withdrawable feeder being equipped with an angle encoder according to the invention. The angle encoder comprises a stator that supports first and second transmitting electrodes and first and second receiving electrodes, and a rotor which supports an incremental coupling electrode and an absolute value-coupling electrode. The incremental coupling electrode is designed such that the first electrostatic field is modulated by a change in capacitance in response to a change in the rotational position of the rotor, while the absolute value-coupling electrode is designed such that the second electrostatic field is modulated by a change in capacitance in response to an absolute rotational position of the rotor. A signal processing circuit detects the first and second modulated electrostatic field and determines a measured value for the position in response to the detected field. The at least one first and second transmitting electrode and the at least one first and second receiving electrode are coplanar to one another.	04-01-2010

20080224054	Photon detection device - The present invention discloses a photon detection device that is adapted to detect at least one packet of photons. The photon detection device may include a photon-sensitive element having an output, an amplifier; and a non-linear feedback (NLF) element. The photon-sensitive element generates charges upon the engagement of at least one photon packet therewith. An increase from a first number of charges in the photon-sensitive element to a second number of charges, results in a corresponding increase of a first reset time required to reset the first number of charges to a respective second reset time required to reset the second number of charges in the photon-sensitive element, whereby the reset time is non-linear to with respect to an increase in the charges. Additional and alternative embodiments are described and claimed.	09-18-2008

20080202865	Wheel Brake Comprising a Wear Sensor - A brake for a vehicle wheel which is mounted in such a way that it can be rotated in relation to a wheel support, the brake including a frame which is fixed to the wheel support, and additional mobile and fixed friction elements. The inventive brake also includes a device for measuring a parameter representing the energetic capacity of the brake. The measuring device includes a capacitive sensor and an information processing unit, the capacitive sensor having two measuring reinforcements mounted face-to-face and carried by the frame, and a dielectric screen carried by a friction element which can be displaced by the action of each actuator. The dielectric screen slides between the two reinforcements during the clamping of the friction elements in order to modify the capacity of the condenser formed by the two measuring reinforcements. The brake is useful in an aeroplane.	08-28-2008
