Systems and methods determine the level, density, and/or temperature of a fluid based on the fluorescence of a material within an optical waveguide slab at least partially immersed in the fluid.

Electro-optic fluid quantity measurement system

Methods and systems detect the presence of a fluid, such as water, based on a reflection of optical energy from the fluid. Methods and systems also determine the concentration of a constituent element in a mixture based on a reflection of optical energy from the mixture.

Methods and systems for detecting and/or determining the concentration of a fluid

Methods and systems are provided for determining the density and/or temperature of a fluid based on the manner in which optical energy is affected as the optical energy propagates across a gap between opposing end faces of optical waveguides, or the manner in which the optical energy is reflected from interfaces of optical waveguides and the fluid.

Systems and methods for determining level and/or type of a fluid

Systems for providing optical energy comprise an LED, a detector of optical energy, such as a photodiode, that measures the intensity of optical energy emitted by the light-emitting diode, and a controller. The controller adjusts the intensity of the optical energy emitted by the LED based on the intensity measurement provide by the photodiode, to maintain the intensity of the emitted optical energy at a desired level.

Systems and methods for generating optical energy using a light-emitting diode

Methods and systems are provided for determining the density and/or temperature of a fluid based on a reflection of optical energy directed at the fluid.

Methods and systems for determining the density and/or temperature of fluids

A system for maintaining a business record includes a main menu having a plurality of modular expense routines and a plurality of modular operational assistance routines. All the modular routines are individually identified and selectively callable by entering an individual alpha-numeric identifier for the particular module selected.

Method for expense report storage and calculation

Disclosed herein is a means for evacuating the odors associated with toilet use away from the environment of the bathroom and into the sewer. Vent means are provided around the periphery directly below the toilet seat, and impelling means are provided to channel the air traversing through these vents into the sewer outlet remote from the bathroom interior.
