Abstract: A pre-filled, single-use, disposable medication chamber for use in a medical nebulizer system that delivers a mist of properly sized aerosol particles of medicament to the patient. The nebulizer can be effectively used in conjunction with conventional nebulizer cap, tee and mouthpiece devices that interface with the patient.

Abstract: A method for scanning an object is provided. The method involves placing the object on a scanning platform. The scanner has a plurality of cameras positioned around the object to be scanned. The scanned object can be a foot, among other things, and the scanner is positioned at a predetermined incline so that the foot is evenly supported. A positioning system including at least one sensor is used to determine if the foot is located within a predetermined scanning area. The method can be used to measure foot dimensions for the production of shoe lasts and construction of shoes. The method can be used in a system for selecting shoes that properly fit.

Abstract: A scanner has a plurality of cameras positioned around an object to be scanned. The object is illuminated by unstructured light and the object is covered by a textured surface. The cameras can be arranged as pairs and each camera pair is supported on a single support. The scanned object can be a foot, among other things, and the scanner is positioned at a predetermined incline so that the foot is evenly supported. Method for attaching the camera pairs on the support, method for calibrating the camera pairs and method of scanning the foot to provide shoe sizes and shoe lasts are also disclosed.

The cameras can be arranged as pairs and each camera pair is supported on a single support. The scanned object can be a foot, among other things, and the scanner is positioned at a predetermined incline so that the foot is evenly supported. A positioning system, either visual or automatic, is included on the scanner platform. If automatic, a sensor array is affixed to the platform such that a scan will only initiate when certain sensors or combinations of sensors are ON. Method for attaching the camera pairs on the support, method for calibrating the camera pairs and method of scanning the foot to provide shoe sizes and shoe lasts are also disclosed.

Abstract: An valve actuator in a hydronic heating and cooling system includes a motor for changing the position of a valve, a switch for switching power to the motor, and a sensor for detecting the arrival of the valve at a desired position and for stopping the motor without using a mechanical stop. The motor's power source includes a capacitive power source which can be used to drive the motor under low-power conditions. A worm gear is used in the drive train, and combined with a clutch assembly to permit the valve to be operated manually.

Abstract: A zone valve for use in a hydronic system, the valve including a ball element through which liquid flows in an axial direction, a valve casing enclosing a ball element, a valve seat in contact with the ball element and the valve casing, the valve seat having a notch to receive an O-ring, an O-ring installed in the notch, and wherein the notch has a surface inclined with respect to the axial direction so that an axial force on the valve seat causes the O-ring installed in the notch to be compressed to improve a seal between the valve seat and an internal bore of the valve casing.

Abstract: An wet-rotor hydronic heating/cooling circulator in which a check valve is positioned at the inlet eye of the pump impeller, where it can easily be serviced by removing the circulator motor and impeller. The check valve is preferably in the form of a valve subassembly that is removably inserted into an opening at the eye.

Abstract: An integrated zoning circulator includes a priority controller, integral with the zoning circulator, for determining the priority given to the circulator in an individual zone of a multi-zone hydronic system. The zoning circulator also includes a priority circulator system for a multi-zone hydronic system having a zoning circulator at each zone, a plurality of control boxes each having a thermostat, one control box being associated with each circulator, and, a plurality of priority controllers, one priority controller being associated with each control box. Each priority controller, when activated, functions to assure that when the associated thermostat calls for the circulator to operate, other circulators in non-priority mode are prevented from operating simultaneously.

Abstract: A zoning circulator for circulating fluid within a zone in a hydronic heating or cooling system includes a zoning circulator controller including a speed regulating circuit for controlling the speed of a circulator motor. The circulator controller also includes an override circuit for operating the circulator at a high speed, high starting torque for several seconds to overcome frictional resistances between the moving parts of the motor and then tapers down to the speed established by the speed regulating circuit.

Abstract: An integrated wet-rotor zoning circulator for circulating fluid within a zone in a hydronic heating or cooling system. The zoning circulator has three primary components: a motor, an impeller casing, and a controller. The controller, which is integrated with the motor, houses a voltage transforming device (e.g., a transformer) and a switching device (e.g., a relay). When a thermostat in the zone being served by the zoning circulator closes, the switching device closes and the pump is activated.
