Abstract: A controller system is provided for controlling the power boost operation of an internal combustion engine by increasing fuelling, the controller means comprising a fuel controller for controlling the rate of fuel supplied to the engine and for supplying an increased rate of fuel in response to a power boost demand signal. The controller system further includes a first timer for measuring a first time period during which the power boost signal is supplied to the fuel controller, a comparator for supplying a prevent boost signal when the first time period exceeds a maximum boost time period, and a second timer for preventing the fuel controller from supplying the increased rate of fuel for a second time period in response to the prevent boost signal.

Abstract: One embodiment of the present invention comprises a tee marker sign (90) which includes a graphic representation of a particular golf hole, number 10, which includes three separate tee boxes--a ladies' tee (92), a men's tee (94) and a championship tee (96). The tenth hole includes a water hazard that is depicted on sign (90) at (100). A golfer teeing off on the tenth hole needs to know the distance to the pin from the tee box. The golfer also needs to know the distance to the water hazard (100). As such, sign (90) includes settable distance indicators associated with each tee box and the distance from each tee box to the water hazard (100).The blue tee box includes distance indicator (102), that is set using selector dial (104). Manipulating selector dial (104) changes the value in distance indicator (102). Adjusting the selector dial (104) also changes the distance simultaneously in distance indicator (106). A distance indicator (108) and a distance indicator (110) are associated with the men's tees.

Abstract: A distance indicator (10) is provided that comprises a housing (12). Distance indicator wheels (22), (24) and (26) are provided through openings (14), (16) and (18) of the housing and the information indicator (28) specifies the point from which the distance indicated by the distance indicator wheels (22), (24), (26) is measured. An information indicator (28) is provided through an opening (20) of the housing. The distance indicators are controlled using selectors (46), (48) and (50). The information indicator is controlled using a selector (44). The distance marker (10) enables the distance on a golf hole to be calculated by groundskeepers and to be reflected exactly for any placement of the tees on a pin on a given day.
