Abstract: The present invention is directed to a massage apparatus for a massage chair wherein massage benefits or effects are provided to a back body area, a seat or bottom body area, and a thigh body area of a user. Massage benefits or effects may also be provided to a head and neck body area of the user. The massage apparatus includes a frame and a massage device. Also, the present invention is directed to a massage chair that includes a massage apparatus and at least one health monitoring device or system. As a non-limiting example, the at least one health monitoring device or system is a portable, wrist blood pressure and heart rate monitoring device that is manufactured and/or programmed to measure or obtain blood pressure and heart rate of the user right at or near the massage chair when the user is preferably positioned on the massage chair.

Abstract: A system including a flow sensor coupled to a fluid line and operable to determine flow rate data of a fluid flowing through the fluid line and communicate the flow rate data of the fluid to a multi-sense device. The multi-sense device coupled to the fluid line and operable to monitor characteristics of the fluid flowing through a filter element. The multi-sense device including a microcontroller coupled to a first, second, and third sensors. The microcontroller executing instructions for determining a pressure differential across the filter element using the flow rate data from the flow sensor, the first pressure of the fluid from the first sensor, the second pressure of the fluid from the second sensor, and the temperature of the fluid from the temperature sensor.
