Abstract: An apparatus for forming a color image of a scene and a method for utilizing that apparatus are disclosed. The apparatus includes a plurality of pixel sensors. Each pixel sensor includes a first photodetector includes first main photodiode and a first floating diffusion node. The first main photodiode is characterized by a first light conversion efficiency as a function of wavelength of a light signal incident thereon. The first floating diffusion node includes a parasitic photodiode characterized by a second light conversion efficiency as a function of the wavelength. The second light conversion efficiency is different from the first light conversion efficiency as a function of wavelength. A controller generates an intensity of light in each of a plurality of wavelength bands for the pixel sensor utilizing a measurement of the light signal by each of the first main photodiode and the first parasitic photodiode in that photodetector.

Abstract: A poolside connector system and method for use with swimming pool race timing systems and signaling devices. A deck plate or similar poolside signal junction is provided with an optical receiver terminal, and a cable connection from a poolside signaling device such as a touchpad or backup button is provided with an optical transmitter terminal that can be plugged into the deck plate terminal. Electrical signals from the touchpad and backup button representing completed laps are transmitted as optical signals to the deck plate junction. The optical connection at the deck plate is non-conductive and electrically sealed from the poolside environment, and thus has no exposed electrical terminals to corrode. The low voltage DC current on which the optical terminals operate is provided in sealed fashion to the electrically insulated optical terminals, in a preferred form via an inductive power coupling whose halves are sealed in the deck plate and the removable cable connection.
