Abstract: A UV exposure dosimetry system includes at least one UV sensor that measures the UV irradiance intensity. The system can generate extrapolated UV intensity data based on measured UV intensity data to correct unreliable UV measurement due to inconsistent irradiation of UV light. The system integrates the extrapolated UV intensity data over time to calculate real-time UV dosage and vitamin D production by taking into account factors including UV sensor location, body surface area, clothing coverage, and sunscreen usage. Based on the measurement, the system can predict the time remaining to skin burn and the time remaining to reach daily goal of vitamin D production. The system is also adapted to measure sun exposure time based on the corrected UV intensity over a period of time. The UV dosimetry system supports multi-user control through an advanced and user friendly input and output interface.

Based on the measurement, the system can predict the time remaining to skin burn and the time remaining to reach daily goal of vitamin D production. The system can also estimate UV intensity for a time in the future at a geographic location based on the forecast UV index data, and predict UV dose and vitamin D generation for the user corresponding to user defined scenarios. The UV dosimetry system supports multi-user control through an advanced and user friendly input and output interface.

Abstract: A UV dosimetry system comprises a wearable unit and a mobile computing device. The wearable unit measures the UV irradiance intensity and wirelessly communicates with the mobile computing device. The UV dosimetry system supports multi-user control and can link one mobile computing device with multiple wearable units. The UV dosimetry system processes the measured UV irradiance intensity to calculate the UV index (UVI) and the sensor site specific UV dose. It can also calculate the total absorbed UV dose and vitamin D production by taking into account user specific factors. The UVI data measured by a plurality of UV meters such as the disclosed UV dosimetry system are crowd sourced to a remote server together with the location and time data of the measurement. The remote server excludes invalid UVI measurement and generates UVI maps showing time-varying distribution of UVI data at different locations.

Abstract: A hydro massaging tub is used for massage treatment wherein the treatment is performed by ozone-mixed warm air or water jets distributed adjacent the bottom wall of the tub all about its circumference. Ozone generated by an ozone generator is injected in an air distribution duct to sterilize the air distribution system and help clean the skin of the bather's body. The oxygen liberated in the water and the air improves the quantity of oxygen in the bather's environment so that oxygen intake through the skin and lungs is facilitated. A mobile air jet and section control of the air jets enable the bather to massage selective body areas with adjustable intensity of sections of the massage to achieve a desired effect. In one embodiment, orientable valves are mounted in the air jet holes for adjusting the orientation of the air jets. In another embodiment, optical fibers or light emitting diodes are provided to emit light frequencies in the water turbulence for physiological and therapeutic effects.

Abstract: A hydro-thermo massaging tub and method of massage treatment wherein the treatment is performed by warm air jets distributed adjacent the bottom wall of the tub all about its circumference. Air jets are formed by holes made in the tub wall with the longitudinal axis of the holes oriented less than 45.degree. from the plane of the bottom wall. The jets communicate with an air distribution duct which is fed hot air under pressure by a blower. Controls are also provided to vary the pressure of the air as well as the temperature thereof. Warm air jets are released in the water contained within the tub to impart turbulence in the body of water to create acupressure massaging flows of warm air jets and water flows from opposed sidewalls and end walls of the tub towards a central area of least turbulence which is occupied by the body of a person. The acupressure massaging flows perform a massaging action all about the body simultaneously.

Abstract: A game apparatus receives tokens pitched toward it and provides a score corresponding to the number and location of tokens it receives. The apparatus includes a box-like frame (20) that carries a horizontally disposed target board (22). The target board (22) includes a plurality of openings (38) formed therein. The openings (38) are arranged in a matrix of multiple rows and multiple columns and configured to receive the tokens (42) pitched into them. Beneath the target board (22) are a plurality of chutes (40), one chute associated with each opening (38). Within each chute (40) there is a token guide mechanism (54) for directing any coin-like tokens (42) received in that chute through a detection passage (60). A sensor (88) is mounted to each token guide mechanism (54) for detecting the presence of a token (42) within the detection passage (60), the presence of the token being indicated by a detection signal applied to the sensor output.
