Abstract: A mower may have a frame, a cutting deck coupled to the frame, a side discharge opening on a lateral side of the cutting deck, a discharge chute coupled to the lateral side of the cutting deck, a mounting frame coupled proximate the discharge opening, the discharge chute movable between an extended position and a retracted position. A distal end of the discharge chute is spaced away from the side discharge opening in the extended position. The distal end of the discharge chute being positioned such that the top edge of the discharge chute is substantially parallel (e.g., +/?10 degrees) to the mounting frame in the retracted position.

Abstract: A magnetic signal noise reduction and detection system has inputs configured to receive data from a first total field scalar magnetometer, data from a vector magnetometer, and data from a position, velocity and heading sensor, a signal processor configured with a pre-processor system, an adaptive noise cancellation system and a detection system, the pre-processor system configured to carry out initial processing of data received. The pre-processor is configured to convert data to the frequency domain and pass the converted data to the adaptive noise cancellation system. The adaptive noise cancellation system is configured to carry out multivariate regression on the converted data to reduce detected noise. The detection system is configured to detect magnetic anomalies and output information in real time about the magnetic anomalies to a user interface.

Abstract: A method of calculating accounting encumbrance adjustments for a purchase order associated with a first allocation of a budget includes determining that the purchase order has been closed, where the closure prevents additional processing associated with the purchase order by an invoice processing system; receiving a request to reopen the purchase order, where the request is associated with an additional cost; causing a determination to be made as to whether a second portion of the budget should be allocated, where the second portion of the budget corresponds to the additional cost; and in response to a determination that the second portion of the budget can be allocated: causing the second portion of the budget to be allocated, reopening the purchase order, and sending an indication to the invoice processing system that the purchase order is reopened.
