Abstract: A fitness equipment unit has a controller that actuates a light between different states in response to service conditions. In one implementation, actuation of the light is based upon a combination of at least two of: a mileage parameter of the fitness equipment unit, a sensed electrical current of the fitness equipment unit, a sensed temperature from the fitness equipment unit and a sensed position of a portion of the fitness equipment unit. In another implementation, actuation of the light is based upon a combination of the first and second service conditions selected from a group consisting of: a connection error service condition; a part wear service condition; a motor/actuator error service condition; a sensor error service condition; a processor error service condition; and a power supply error service condition and further based upon a prioritization of different severity levels of the first and second service conditions.

Abstract: Belt wear of a treadmill is monitored. In one implementation, samples of electric current draw of a treadmill at different speeds of the treadmill belt of the treadmill are received. A value of each sample is differently weighted based on a speed of the treadmill belt at which the value of each sample was obtained. A belt wear notification is output based on the different weighted values of the samples.

Abstract: Belt wear of a treadmill is determined. Samples of electric current draw of a treadmill at different speeds of the treadmill belt of the treadmill are received. A value of each sample is differently weighted based on a speed of the treadmill belt at which the value of each sample was obtained.

Abstract: An elliptical exercise device including a frame having a pivot axis, a foot link, a coupling, a swing arm, an engagement mechanism, and a guide system. The foot link has rearward, forward and foot support portions. The foot support portion has a central location. The coupling couples the rearward portion to the pivot axis so that the rearward portion of each foot link travels in a closed path relative to the pivot axis. The engagement mechanism has a first portion coupled to the swing arm and a second portion coupled to the foot link at a location rearward of the central location. The guide system supports the forward portion of the foot link along a preselected reciprocating path of travel as the rearward portion of the foot link travels along its path of travel. The guide system is selectably positionable in a plurality of different positions.

Abstract: An exercise device is provided including a foot link having a rearward end and a forward end. An adjustable stride mechanism is provided. The adjustable stride mechanism includes a primary gear and a secondary gear. The primary gear is sized larger relative to the secondary gear. A primary crank connects the primary gear and the secondary gear. A timing belt connects the primary gear to the secondary gear. The primary crank and the timing belt enable the secondary gear to rotate around the primary gear. A secondary crank is pivotally attached to the secondary gear and to a foot link. The secondary crank creates an ellipse-shaped path for the foot link as the secondary gear rotates around the primary gear. Thus, the foot link motion combines an at least a dual ellipse motion. An automatic adjusting mechanism can be provided to adjust the adjustable stride mechanism.

Abstract: An elliptical exercise device includes a frame having a first pivot axis and a longitudinal axis, at least one foot link and at least one swing arm. The foot link is coupled to the frame and is constrained to move in an orbital path approximately parallel to the longitudinal axis. The swing arm is also coupled to the frame and has a reciprocating movement whereby a natural “stride” movement of the arm of a user is replicated. The swing arm operates independently from the foot link. The natural “stride” movement of the arm of the user grasping the arm link follows a generally concave motion relative to the ground. The length of the movement of the arm of the user is defined by the user. A different resistive load can be applied on the arm apparatus than on the foot links.

Abstract: A trailer hitch assembly that includes a hitch mount member having a chassis mount plate, a hitch mount plate having a plate mounting aperture bored entirely therethrough and four spaced alignment bores formed therein, and an extension arm in connection between the chassis mount plate and the hitch mount plate; a multi-ball hitch unit including a cross-shaped ball support structure including four support arms extending radially outward from a center portion having a structure mounting aperture formed therethrough; three trailer mount balls, each secured to the end of one of the four support arms; and a pintel hook secured to the end of the remaining one of the four support arms; and a positioning mechanism including a bolt assembly including a bolt having a cap portion and a threaded shaft portion; a securing nut threadable onto an end of the threaded shaft portion; a biasing spring; and two alignment pins, the alignment pins extending perpendicularly with respect to two of the four support arms and being pos
