Abstract: A novel fuel waste variable identification and analysis system is capable of analyzing real-time on-board diagnostics (OBD) information of a vehicle from a remote monitoring station unit. This novel system analyzes, quantifies, and/or predicts various fuel waste variables for a particular vehicle and its driver. Preferably, various fuel waste variables are normalized with a novel metric called “RPG,” or “engine rotation per minute per gallon of fuel.” Utilizing the RPG as a normalizing factor for fuel waste variable measurements uniquely enables a realistic representation of a driver's fuel wasting behaviors in context of the particular vehicle's inherent, native, and average fuel consumption characteristics.

Abstract: A method that provides increased flexibility to measure dynamic range of a rotating system is provided. The method includes the steps of: providing a first rotating member; providing a second rotating member suitably engaged to the first rotating member; providing a set of sensors disposed to sense variations in characteristics along a circumference of the first member and the second member respectively; providing a controller for receiving information sensed by the sensors; determining a rate of rotation of the rotating members; selectively using the sensed information thereby at different rate of rotation different amount of the sensed information is used.

Abstract: An apparatus for measuring frequency of rotation of a shaft, connectable to his shaft through a reducing gear having a solenoid clutch at the output thereof, has the output shaft of this solenoid clutch associated with a driver and a return spring. The driver is adapted to rotate a memory mechanism through an actuator fast with the shaft of this mechanism. The shaft of the memory mechanism carries an indicator of the frequency of rotation of the shaft and an overrunning clutch operatively connected with a solenoid brake controlled by a pulse generator. The pulse generator is successively connectable to the solenoid clutch to perform a measurement of the frequency of rotation of the main shaft, and to the outer cage of the overrunning clutch to register the frequency of rotation of the shaft, which is being measured.

Abstract: An improved magnetic return mechanism, especially useful in timing devices of the type including a motor means for driving a member at a given rotational velocity about a given axis and from a selected angular position, means for indicating when the member has been driven a given angular amount corresponding to a cycle time, means for releasing the member for free rotation about the given axis back to the selected angular position, and return means for rotating the member from a position angularly spaced from the selected position to the selected position.

Abstract: A timing device including an internal motor which rotates a pointer on an elapsed time dial which indicates the time periods required for the performance of respective events and for indicating the differences between the time periods when each time period is successively indicated on a common dial. A drive mechanism is movable between two positions. In one position the single time dial is caused to indicate increments of time for performing a series of successive events while in the other position the same single dial is caused to indicate decrements of time of the previously recorded periods of time. A timing governor is provided as a part of the drive mechanism, so as to regulate the output speed of the drive mechanism.

Abstract: A device adapted for special use in a reset timer/counter unit to return various digital counting subwheels to their reset condition after a timing or counting cycle. The device includes a first ring formed from a permanently magnetizable material having a generally circular first pole surface with a set of opposite polarity magnetic poles arranged in a selected pole pattern on the first pole surface and means for securing the first ring onto one of the subwheels or other device to be returned to a selected position. The second ring formed from a permanently magnetizable material is provided with a generally circular second pole surface generally facing the first pole surface and having opposite polarity magnetic poles arranged in a pole pattern matching the selected pattern of the first surface with poles of the first surface generally facing opposite polarity poles of the second surface when the members to be controlled are in a selected angular returned, or known, position.

Abstract: The present invention relates to a counter feed mechanism as used in digital clock comprising a cam member adapted for advanced rotation and another cam member adapted for delayed rotation both arranged on a common axis so that the advanced rotation of the first-mentioned cam member under a drive force transmitted from a clock mechanism twists a coil spring stretched between both cam members, which is, in turn, charged with energy for rotation of the second-mentioned cam member and, upon rotary displacement of the first-mentioned cam member by a predetermined angle, said second cam member is released to be rotated at once so as to advance a rotary wheel step by step.
