Abstract:
Systems and methods may provide for receiving an electrical measurement signal from a first photodetector coupled to a first waveguide and determining a total intensity level of reflected light in the first waveguide based on the electrical measurement signal. Additionally, a perspiration level of skin in contact with the first waveguide may be determined based on the total intensity level of the reflected light in the first waveguide. In one example, an electrical control signal is received from a second photodetector coupled to a second waveguide that is physically isolated from the skin, wherein the total intensity level of the reflected light in the first waveguide is determined further based on the electrical control signal.

Abstract:
A diminutive ultraviolet radiation monitoring device comprising a sensor (10, 35), integrator (22, 43) and control (17, 51). The sensor (10, 35) senses impinging ultraviolet radiation and generates a sensing signal commensurate to the magnitude of the radiation. The integrator (22, 43) integrates the sensing signal in accordance with a first timing function related to an admonished accumulative effect of the radiation on a person's skin, and generates an active signal proportional to the integration. The control (17, 51) monitors the active signal and issues an alarm when it attains a threshold level related to the optimum cumulative radiation to which the skin is desired to be exposed. The integrator includes a memory (16, 45) to store the active signal magnitude and allows the magnitude to diminish in acordance with a second timing function related to an admonished decay in the residual effect of the previous radiation on the skin after it is removed from the radiation or vice versa.
Abstract:
Conventional mobile electronic devices have a room for improvement in control on a plurality of sensors to detect information. For example, a mobile electronic device 1 includes a plurality of sensors, a detector that detects a biological reaction by one of the sensors, and at least one controller 10 that performs control to change a detection cycle of other sensors according to whether the biological reaction is detected. For example, the controller 10 changes the detection cycle used when the biological reaction is detected to a detection cycle shorter than the detection cycle used when no biological reaction is detected.
