Abstract: A system is provided for identifying and reducing noise in a therapeutic procedure. For example, the system may be configured to measure one or more signals with cardiac activity. The system may be configured to then identify one or more sources of noise that are distorting the one or more signals with cardiac activity and may reduce the one or more sources of noise from the one or more signals with cardiac activity. Subsequently, the system may be configured to determine one or more aggregate cardiac-derived metrics and/or save processed cardiac data based on the one or more signals with cardiac activity with the one or more sources of noise reduced. Additionally, the system may be configured to determine one or more parameters for applying an electrical signal to an anatomical element of a patient based on the one or more aggregate cardiac-derived metrics and/or saved processed cardiac data.

Abstract: A method provides for permission-based access to personal information over a communication network. The method includes entering specified owner personal information in an owner terminal, by an owner, to establish a secure owner profile, which is stored in an owner database. The method also includes entering specified user personal information in a user terminal, by a user, to establish a secure user profile, which is stored in a user database. The method further includes entering a user request in the user terminal requesting permission to receive a designated piece of the owner personal information from the secure owner profile. A server determines whether to approve the user request; and provides permission to use the designated piece of the owner personal information to the user over the communication network after the user request is approved by the server.

Abstract: A recovery tank is provided for a floor cleaning unit. The recovery tank includes an inlet opening and a duct fluidly connected to the inlet. The duct extends horizontally within the tank adjacent a side wall the recovery tank for directing air and liquid from the inlet opening in two opposing directions. A lid covers the tank and has an outlet opening for directing air out of the recovery tank. A pair of shields depends downwardly from the lid and extends from the duct to the side wall of the recovery tank. The outlet opening of the lid is located between the shields such that the shields prevent liquid from coming out of the duct and entering the outlet opening of the lid.

Abstract: A novel carpet extractor is disclosed having a first cleaning liquid conduit that communicates a supply reservoir with a cleaning liquid distributor via a first valve and a second cleaning liquid conduit that communicates the supply reservoir with the liquid distributor via a second valve. The first valve is actuated by a main trigger and the second valve is actuated by a surge button, both of which are conveniently located in the hand grip on the handle of the machine for propelling the machine over a floor surface. A first normal flow of cleaning liquid is obtained for normal cleaning by depressing the trigger and a second greater flow of cleaning liquid is obtained by depressing the button and the trigger simultaneously. A mechanism is preferably included that will open the first valve in the event an operator depresses only the surge button.

Abstract: A portable compact extractor having permanent solution and recovery tanks integrally formed in a single main tank portion, with a removable power head attached to the top of the main tank. A fill port passes through the powerhead into the cleaning solution tank and a pour spout is formed in the recovery tank. With this construction, the cleaning solution tank may be filled with water and, if desired, detergent, by pouring the water and detergent into the fill port in the power head, and the recovery tank may be emptied as desired simply by tipping the unit and pouring the contents of the recovery tank out the pour spout and down the drain, without ever having to remove any tanks, bottles or the power head from the unit, or disconnect and reconnect any tubes. A carry handle is located on the powerhead to facilitate transportation of the unit, removal of the power head from the main tank for cleaning the tanks when desired, and to facilitate pouring the contents of the recovery tank out of the pour spout.

Abstract: An air/liquid separator is disclosed that is formed by a recovery tank having a hollow, preferably transparent, removable lid on a recovery tank of a wet pickup suction cleaner. The lid has a wall therein dividing the lid into an inlet/separating chamber and an exit chamber. Liquid and dirt entrained working air enters the inlet chamber and flows horizontally across the inlet chamber over a discharge opening passing through the lid bottom plate, such that the stream of dirty liquid and air is redirected downward through the discharge openings into the recovery tank by a pair of ribs in the inlet chamber. The exit chamber fluidly communicates with the interior of the recovery tank through an exit opening passing through the lid bottom plate. A vacuum is preferably drawn upon the exit chamber by an electric fan for providing the required working air flow through the combined air/liquid separator.

Abstract: The present invention teaches a combined air/liquid separator and recovery tank for use on a hot water carpet extractor. The combined tank and separator are particularly suited for an upright style of carpet extractor and features easy removal for emptying the recovery tank at a site remote from the extractor.

Abstract: An air/liquid separator is provided in a hollow, preferably transparent, removable lid on a recovery tank of a wet pickup suction cleaner. The lid has a wall therein dividing the lid into an inlet/separating chamber and an exit chamber. Liquid and dirt entrained working air enters the inlet chamber and flows horizontally across the inlet chamber over a plurality of discharge openings passing through the lid bottom plate, such that the stream of dirty liquid and air is redirected downward through the discharge openings into the recovery tank. The plurality of discharge openings in the lid bottom plate are arranged generally progressively along the stream of liquid and air entering and flowing across the inlet chamber. The discharge openings preferably increase in size moving downstream in the inlet chamber, i.e. away from the entry into the inlet chamber. The exit chamber fluidly communicates with the interior of the recovery tank through an exit opening passing through the lid bottom plate.
