Abstract: A method and system is disclosed that provides: (a) a theoretical framework for designing psychological research that uncovers individual decision-making networks, both in terms of sampling requirements and questioning methods, (b) an implementation interface to schedule and administer the appropriate question sequences between an interviewer and a given individual, in real-time, via a web-based system, and (c) a coding and analysis system to summarize and quantify the potential of alternative decision structures to be used to optimize the development of marketing and communication strategies.

Abstract: The present disclosure generally provides systems and methods of controlling an ion concentration in water, for example, a silver ion concentration. The method of depositing ions in the water includes determining a conductivity level of the water using a reference probe. A power level based on the determined conductivity level is also determined. Power is applied to a deposition probe corresponding to the determined power level using a first electrical circuit, and a concentration of ions are deposited in the water.

Abstract: An air purifier (10) held in a housing (12, 14) with an ambient air inlet (16) and an air outlet (18) and defining an airflow path therethrough for treating ambient air, a filter (disposed in the airflow path and having an air permeable media for communicating air therethrough while retaining particles carried in the flow of air. A purification device attaches to an intermediate chassis in the airflow path for treating the air moved by a fan (70) into operative engagement with the purification device within the housing and out the air outlet. A controller operates the purification device by sensing an operative status of the purification device.

Abstract: A portable air purifier for purifying air in selected occupied spaces, comprising a base for attaching to a support in the space, a housing pivotally mounted to the base, a fan mounted within the housing and having an air inlet and an air outlet for communicating air through the housing and at least one air treatment device supported in the housing for acting upon air communicated by the fan.

Abstract: A metalwood golf club head including upper and lower surfaces, a front ball striking face and a curved rear surface is characterized by a concave projection in the lower surface extending from the face toward the rear surface. The depth of the concavity in the projection is governed by the loft of the club face, with the depth being greater for higher lofted clubs. The concave projection enables the club head to strike to golf ball resting on the ground, and particularly in a poor lie such as in a bunker or deep rough, without the head becoming buried in the ground.
