Abstract: A protective circuit protects against overheating of the stator windings of an EC motor. The stator windings are connected to a semiconductor output stage which is designed for time-offset control of the stator windings using a driver circuit of a commutation controller. The protective circuit has two redundant sensor circuits, wherein two resistance-dependent sensor elements connected in series are provided in the first sensor circuit and one resistance-dependent sensor element is provided in the second sensor circuit. The first and the second sensor circuits are connected, respectively, to two evaluating circuits separated from each other and cause an interruption of the driver circuit using switch-off means when a system-specific resistance value of the first sensor element or the one sensor element associated with the second sensor circuit is reached.

Abstract: A humidity sensor having a housing, a data logger that has such a humidity sensor as well as a evaluation method for the humidity sensor or the data logger. The housing of the humidity sensor has a recess in which a humidity sensor element is situated. To protect the humidity sensor element against the ingress of water, a membrane is provided that covers at least a portion of the recess and thus defines a detection volume around the humidity sensor element. This membrane allows for an exchange of air with the surroundings so that the humidity sensor element is able to detect the air humidity. It is also designed in such a way that it prevents the ingress of water. The detection volume is designed to be as small so that the humidity of the detection volume adapts quickly to the surrounding climate that is to be measured.

Abstract: Apparatuses, methods, and systems for tracking movements of golf clubs and alerting a golfer when one or more golf clubs are misplaced from a group of golf clubs. A peripheral unit is associated with and affixed to each of a number of golf clubs, and transmits signals that are detected and collectively processed by a base unit to determine the status of those clubs. A club may be designated as misplaced based on the sequence and timing of status events, upon which an alarm is activated to alert the golfer. Also the base unit may process signals regarding movement of golf clubs in conjunction with location data from a Global Positioning System device to obtain information regarding the user's golf performance.
