Abstract: Embodiments of eyeglasses are provided. The glasses comprise a frame comprising a first and second lens connected by a bridge. Temple pieces extend from either side of the frame. The hinge or hinge point between the temple pieces and the frame can be within the plane of the glasses allowing the temple pieces to fold flat or near flat against the frame. The thickness of the glasses can be less than about 3.5 mm (e.g., 2.6 mm) in a folded configuration.

Abstract: Embodiments of thin eyeglasses are provided. The eyeglasses comprise a first and second lens connected by a resilient bridge. The eyeglasses comprise a first and second ear piece connected to the first and second lens by a first and second hinge. One lens can be rotated about the hinge and over the other lens to place the eyeglasses in a compact configuration.

Abstract: A water quality management system for a water installation containing water. In some embodiments, the system includes a water quality measurement module adapted to monitor the water quality of the water in the water installation and to send water quality information to a controller; a chemical dispensing module adapted to dispense chemicals directly into the water installation in response to signals from the controller; and a communication mechanism configured to provide communication among the controller, the water quality measurement module, the chemical dispensing module and a user.

Abstract: A water quality management system for a water installation containing water. In some embodiments, the system has a water quality measurement module adapted to monitor the water quality of the water in the water installation and to send water quality information to a controller; and a chemical dispensing module adapted to dispense at least one chemical directly into the water installation in response to signals from the controller based on a water quality measurement by the water quality measurement module, the chemical dispensing module comprising a reservoir adapted to contain the at least one chemical, a movable dispenser adapted and configured to advance a fixed quantity of the chemical out of the reservoir and into the water of the water installation in response to signals from the controller.

Abstract: A dispensing system including a handheld dispenser and a dispenser controller. The handheld dispenser may have a housing, a cartridge removably disposed within the housing and containing a dose form to be dispensed, the dose form with an active pharmaceutical ingredient (API), the cartridge having an internal piston movable within a reservoir containing the dose form and a port through a distal tip in communication with the reservoir, the distal tip being sized and configured to be inserted into the user's mouth. A motor disposed in the housing moves the piston to dispense a volume of the dose form from the cartridge through the port. The dispenser controller adjusts the volume of the dose form dispensed by the dispenser based on information about effectiveness of the API in treating a condition of the user.
