Abstract: A control system for use with a turf maintenance vehicle. In one embodiment, the control system may provide a discrete engine speed input that may provide one engine speed command upon actuation, but result in additional engine speed commands depending on an actuation time of the input. In other embodiments, the vehicle may include an electronic controller (EC) providing resettable property statistics for one or more properties. In still another embodiment, the EC may provide a maintenance monitor onboard the vehicle that indicates maintenance status, when maintenance tasks are due or past due, and permanently records historical information regarding maintenance tasks. The maintenance monitor may further adjust a maintenance interval before the maintenance task is again due based upon inputs to the maintenance monitor.

Abstract: A panelized, systems-based, holistic approach towards design, manufacturing and construction is disclosed. In an exemplary system, a core structural metal framing known as stud and track structure refers to the construction of walls and planes using cold-formed steel. The metal framing has two main components, a stud and a track. The disclosed system is a flat pack. A flat pack system is a prefabricated building construction system that uses structurally insulated panels which are prefabricated in a factory, shipped by stacking and assembled on site. The modular panel system is manufactured off-site and includes an exterior facade, insulation and interior walls in a single pre-made modular panel system, which is connected via novel connectors.

Many different features of the pad and/or the adapter-pad interface are configured to improve stiffness characteristics to satisfy both curving and high speed performance of the railcar truck.

Abstract: A tracking loop and associated method for tracking a satellite signal in a GNSS receiver and for determining a line-of-sight (LOS) signal from a plurality of satellite signals received by the GNSS receiver from a satellite. One or more first correlators perform a correlation between a code signal derived from one of the received satellite signals and a plurality of corresponding replica code signals to determine a plurality of code correlation sums comprising a prompt code correlation sum, one or more early code correlation sums and one or more late code correlation sums. One or more second correlators correlate the plurality of code correlation sums with a plurality of replica carrier signals, each having a different Doppler frequency offset, to determine, for each of the plurality of code correlation sums, a set of correlation magnitudes at frequencies of the plurality of replica carrier signals.

Abstract: A stand-up grounds maintenance vehicle including a chassis, a control tower, an implement, and a cover. The chassis is supported upon a ground surface by a plurality of ground-engaging members and extends along a longitudinal axis between a front end and a rear end. The control tower is coupled to the chassis proximate the rear end. The implement is attached to the chassis and is positioned at least partially forward of the control tower. The implement includes an implement drive. The cover extends over the implement drive and is pivotally coupled to the chassis.

Abstract: Various embodiments of a grounds maintenance vehicle are disclosed. The vehicle includes a frame and a control tower disposed at or near a rear end of the frame. The control tower includes a support structure that defines an interior space of the control tower and a nonplanar removable skin connected to the support structure. The removable skin includes a front side disposed over a front side of the support structure and a lateral side disposed over at least one of a left side or a right side of the support structure. A portion of at least one of the front side or lateral side of the removable skin is disposed above an uppermost surface of the prime mover. Further, the removable skin is adapted to be at least partially removed from the support structure to facilitate additional access to the interior space of the control tower.

Abstract: Systems and methods for inhibiting implement-induced stall of a prime mover associated with a turf vehicle. In some embodiments, the vehicle includes an electronic controller (EC) adapted to monitor a speed of the prime mover and detect when the speed falls below a speed threshold. The EC is adapted to automatically disengage a power take-off (PTO) connecting the prime mover to the implement when the speed of the prime mover falls below this speed threshold.
