The first indicator has a first state when the threshold condition is not satisfied and the first indicator has a second state when the threshold condition is satisfied, and the first indicator is coupled to the controller so that the controller is responsive to a change of the state of the first indicator, and wherein the controller is adapted to provide information for display that is indicative of the state of the first indicator. ## Claims ### Claim 1 A system for communicating threshold conditions for use of a powered device to a user, comprising: an engine; a controller coupled to the engine to control starting of the engine; a first indicator associated with a first threshold condition, the first indicator has a first state when the threshold condition is not satisfied and the first indicator has a second state when the threshold condition is satisfied, and the first indicator is coupled to the controller so that the controller is responsive to a change of the state of the first indicator, and wherein the controller is adapted to provide information for display that is indicative of the state of the first indicator; a second indicator associated with a second threshold condition, the second indicator has a first state when the second threshold condition is not satisfied and the second indicator has a second state when the second threshold condition is satisfied, and the second indicator is coupled to the controller so that the controller is responsive to a change of the state of the second indicator, and wherein the controller is adapted to provide information for display that is indicative of the state of the second indicator; and a throttle control including two throttle levers that are each movable between a first position and a second position and wherein the first indicator is associated with a first throttle lever of the two throttle levers and the first indicator is in the first state when the first throttle lever is in the first position and the first indicator is in the second state when the first throttle lever is in the second position, and the second indicator is associated with a second throttle lever of the two throttle levers and the second indicator is in the first state when the second throttle lever is in the first position and the second indicator is in the second state when the second throttle lever is in the second position. ### Claim 2 (depends on 1) The system of claim 1 wherein the first position of both the first throttle lever and the second throttle lever permits powered movement of the device and the second position of both the first throttle lever and the second throttle lever is a neutral position wherein the throttle control does not cause movement of the powered device. ### Claim 3 (depends on 1) The system of claim 1 which also includes an electronic device having a display that is connected with the controller to provide visual information from the controller and wherein the display includes an icon having a first state when the first indicator is in the first state and the icon has a second state when the first indicator is in the second state. ### Claim 4 (depends on 1) The system of claim 1 wherein the electronic display is a touch sensitive display and wherein a start input is provided on the display for selection by touching a corresponding portion of the electronic display, and the start input is not enabled so that touching said corresponding portion of the electronic display does not initiate a start event when the threshold condition is not satisfied and the start input is enabled when the threshold condition is satisfied so that touching said corresponding portion of the electronic display does initiate a start event. ### Claim 5 (depends on 4) The system of claim 4 wherein multiple indicators are provided and each indicator is associated with a different threshold condition, and wherein the start input is not enabled when any one of the threshold conditions is not satisfied and is enabled when all threshold conditions are satisfied. ### Claim 6 (depends on 1) The system of claim 1 wherein a third indicator is responsive to the position of a key which is movable from a first position in which the threshold condition is not satisfied to a second position in which the threshold condition is satisfied. ### Claim 7 (depends on 5) The system of claim 5 which also includes an electronic device having a display that is connected with the controller to provide visual information from the controller and wherein the display includes an icon for each of the multiple indicators, and each icon has a first state when the first indicator is in the first state and the icon has a second state when the first indicator is in the second state. ### Claim 8 (depends on 7) The system of claim 7 which: a) includes a seat and wherein one of the multiple icons visually looks like the seat and wherein the icon that looks like the seat is in the first state when the seat is not occupied by a user and the icon that looks like the seat is in the second state when the seat is occupied by the user; or b) one of the multiple icons visually looks like one of the throttle levers and wherein the icon that looks like the throttle lever is in the first state when said one of the throttle levers is in a first position and the icon that looks like the throttle lever is in the second state when said one of the throttle levers is in a second position. ### Claim 9 (depends on 3) The system of claim 3 wherein the display is part of a handheld mobile device that is coupled to the controller via one or more wires or wirelessly. ### Claim 10 A method of controlling starting of an engine of or powered moving a powered device, comprising: providing at least one indicator associated with a threshold condition, the indicator having a first state when the threshold condition is not satisfied and a second state when the threshold condition is satisfied; determining the state of the indicator at a controller coupled to the engine to control at least one parameter of engine operation; communicating the state of the indicator to an electronics device having a display; visually depicting the state of the indicator on the display with an icon having a first state when the indicator is in the first state and a second state when the indicator is in the second state; changing the state of the icon when the state of the switch changes as communicated from the controller to the electronics device; and presenting a start input that initiates an engine starting attempt when the threshold condition is satisfied, where the start input is provided on a portion of the display that is responsive to touch so that touching said portion of the display initiates an engine starting event, wherein the at least one indicator includes a first indicator that is associated with a first throttle lever of the two throttle levers, and the first indicator is in the first state when the first throttle lever is in the first position and the first indicator is in the second state when the first throttle lever is in the second position, and the at least one indicator includes a second indicator that is associated with a second throttle lever, and the second indicator is in the first state when the second throttle lever is in the first position and the second indicator is in the second state when the second throttle lever is in the second position. ### Claim 11 (depends on 10) The method of claim 10 which also includes the step of wirelessly coupling the electronics device to the controller and wherein the communication between the controller and the electronics device occurs wirelessly. ### Claim 12 (depends on 10) The method of claim 10 wherein the indicator is a switch or sensor having two positions or states. ### Claim 13 (depends on 10) The method of claim 10 wherein there are multiple threshold conditions and at least one indicator associated with each threshold condition, and wherein the start input is presented on the display only when all threshold conditions are satisfied as determined by the state of the indicators. ### Claim 14 (depends on 7) The system of claim 7 wherein the display is part of a handheld mobile device that is coupled to the controller via one or more wires or wirelessly. ### Claim 15 (depends on 8) The system of claim 8 wherein the display is part of a handheld mobile device that is coupled to the controller via one or more wires or wirelessly.
