Abstract: In one set of embodiments, a temperature measurement system may include an analog to digital converter (ADC) to produce digital temperature readings according to a difference base-emitter voltage (ΔVBE) developed across a PN-junction. A clock generating circuit may be configured to provide a sampling clock used by the ADC, which in some embodiments may be a delta-sigma ADC, in performing the conversions. The clock generating circuit may be configured to change the frequency of the sampling clock a specified number of times within each one of the one or more conversion cycles to reduce an error component in the temperature measurement, where the error component is produced by an interfering signal, such as an electromagnetic interference (EMI) signal being coherent with the sampling clock, and/or a noise residing on the voltage supply and also being coherent with the sampling clock.

Abstract: A system for communicating check information to a financial institution is provided. The system includes but is not limited to a check reader, a centralized computer, and a financial institution computer. The check reader retrieves check information from a drawn check. The check information includes an amount of money, a routing number, and an account number. The centralized computer is in communication with the check reader. The centralized computer converts the check information into debit card data for transmission over a debit card network. The financial institution computer is in communication with the centralized computer via the debit card network. The debit card data is transmitted to the financial institution over the debit card network.

Abstract: A three-dimensional and a two-dimensional GPS unit periodically provide coordinate positions of points on the work machine and are combined with a Kalman filter to produce a point of reference on a work machine. The point of reference is improved by combining the position with an inertial position derived from accelerometer data in another Kalman filter. Additionally, the two-dimensional GPS unit provides a heading that is combined with an inertial orientation derived by the angular rate from a gyroscope in another Kalman filter to produce a precise orientation estimate. Inclinometers provide pitch and roll of the work machine. With the point of reference, orientation estimate, pitch, roll and known geometry of the work machine, the invention calculates the location and orientation of machine components and continuously tracks its movement throughout the mine. Additionally, the accelerometers and gyroscope provide position and orientation when the GPS units are inoperable.
