Abstract: A pair of dual chamber mixing pumps are combined which allow for a constant dispense rate profile using motor speed modulation. Each pump is divided into two chambers, the proximal chamber and the distal chamber. The chambers are defined in part by a piston having proximal and distal ends and recessed sections. The pump utilizes one common driving mechanism to axially rotate and laterally reciprocate the piston to provide continuous pumping of fluids with reduced pulsations. Each fluid enters through its own pump inlet and outlet. The pumps are operated 90° out of phase with respect to each other.

Abstract: An improved modular flavor dispenser for dispensing a plurality of different flavors is shown and described. One disclosed modular flavor dispenser includes a controller that is linked to a coordinator or interface with a controller associated with the food or beverage dispenser. For example, an automated coffee machine may include its own controller. The controller of the coffee machine communicates with the coordinator or interface of the modular flavor dispenser which, in turn, communicates with the motor control board or controller of the flavor dispenser. The flavor coordinator board may have a memory with a plurality of recipes stored therein or that information may be communicated from the controller of the coffee machine. The flavor coordinator board is linked to the motor control board which, in turn, is linked in parallel with the plurality of pumps used to dispense the variety of flavors.

Abstract: A manually operated seal/closure system for a fluid dispenser manifold is disclosed. The manifold includes at least one nozzle and, more typically, a plurality of nozzles ranging from more than one to twelve or more. The manifold housing includes a sidewall or other stationary structure. The stationary sidewall is pivotally connected to an arm. The sidewall further includes a lateral slot and a curved slot. The arm includes a proximal end pivotally connected to the sidewall and a distal end with an elongated slot disposed therebetween. The closure system also includes a bracket for supporting a cup and a seal. The bracket is coupled to the arm and the sidewall by a first pin that extends from the bracket through the lateral slot in the sidewall and through the elongated slot of the arm. The brackets also coupled to the sidewall by a second pin that extends through the lateral slot of the sidewall and laterally between the first pin and the manifold.

Abstract: In an elliptical step exercise apparatus distance traveled can be approximated by determining the portion of the ellipse traversed by a foot pedal where the user applies force to the pedal. This portion can be considered equivalent to the amount of foot travel on a treadmill and modified as a function of speed to simulate the gait of a user at various speeds so as to provide an approximation of the distance traveled by a user as if he were running on a treadmill. This process can be further modified for use with an elliptical exercise apparatus where the stride length can be changed such that the simulated distance will be increased with increased stride length.

Abstract: An exercise treadmill is disclosed which includes various features to enhance user operation and to reduce maintenance costs. These features include handlebars with an upwardly curved center section and outwardly flared side portions along with pivoting rear legs for the treadmill frame. The control panel features include snap-in user trays and an overlay covering the numerical key pad along with an auxiliary control panel having a subset of user controls that are larger and more easy to use than the same controls on the main control panel. Maintenance enhancing features include the provision for access panels in the treadmill housing and a belt lubrication system that uses a priming pulse to clear the wax spraying nozzle along with using treadmill operating criteria for scheduling and operating the lubrication system. For injection molded parts such as the control panel, structural strength is enhanced by utilizing gas-assist injection molding to form structural ribs.

Abstract: In an elliptical step exercise apparatus a dynamic link mechanism can be used to vary the stride length of the machine. A control system can also be used to vary stride length as a function of various exercise and operating parameters such as speed and direction as well as varying stride length as a part of a preprogrammed exercise routine such as a hill or interval training program. In addition the control system can use measurements of stride length to optimize operation of the apparatus.

Abstract: In an exercise apparatus having a frame that is adapted for placement on the floor, a pivot axle supported by the frame, a pair of pedal levers, pedals secured to the pedal levers, arm handles connected for motion with the pedal levers and which can utilize a variety of pedal actuation assemblies for generating elliptical motion of the pedal, the stride length portion of the elliptical motion can be increased automatically as a function of exercise parameters such as speed.
