Abstract: Systems and methods are directed to optimizing survey parameters using machine learning. A network system monitors user activity of a plurality of users with respect to an application and provides a notification to users of the plurality of users that satisfy a trigger condition for providing the notification. The network system obtains feedback corresponding to the notification, whereby the feedback indicates whether each of the users accepted, rejected, or ignored the notification. A machine learning model is then trained using input data obtained from the feedback to optimize on one or more parameters used by the network system in providing a future notification. Based on the machine learning model, the future notification is presented to a further set of users using the one or more optimized parameters.

Abstract: The invention provides inoculants for the generation of a biologically active layer in a water treatment or purification device. In some embodiments, the invention provides inoculants for a biologically active zone in a wastewater treatment system or device, for example in municipal wastewater and sewage treatment. In other aspects, the invention provides inoculants for water purification, for example in municipal drinking water purification or in slow sand filtration. Inoculants of the invention increase the effectiveness of the above systems and devices in providing useable water.

Abstract: A disc top dispensing closure which includes a body having an opening and an actuator having a channel mounted to the closure body. The actuator is pivotable about a pivot axis between an open position, wherein the channel and the opening of the body form a continuous fluid path, and a closed position, wherein the channel and the opening of the body do not form a continuous fluid path. The actuator is also rotatable between a locked position, wherein the actuator is not movable between the open and the closed position, and an unlocked position, wherein the actuator is movable between the open and the closed position. The pivot axis is parallel to but offset from a plane in which the longitudinal axis of the closure exists.

Abstract: A swing training apparatus for use with a hand held sports implement having a head and a handle with a longitudinal axis extending between the head and handle includes a housing that is mounted to the implement at a position adjacent the head. A sleeve carried by the housing defines a bore with a bore axis generally parallel to the implement longitudinal axis. A slug is carried by the sleeve in the bore and has a metallic portion defining a first electrical contact. A spring is used to bias the slug into a position spaced away from the implement head. A second electrical contact is positioned to engage the first contact when a preset centripetal force urges the slug to travel toward the implement head when the implement is swung with sufficient force. An indicator emits an audible signal and emits the signal as the implements reaches the preset centrifugal force threshhold.
