Title: Innovations of Keith Kaste
Introduction
Keith Kaste is an accomplished inventor based in San Luis Obispo, California. He has made significant contributions to the field of gas analysis technology, holding three patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is a method and apparatus for detecting a component gas in a sample. This non-dispersive infrared gas analyzer is specifically designed for measuring the concentrations of hydrocarbons (HC), carbon monoxide (CO), and carbon dioxide (CO₂) in vehicle exhaust. The system includes a sample chamber for holding the gas, a radiation emitter that directs a beam through the chamber, and a detector that indicates the amount of radiation absorbed. A series of filters, each transmitting radiation at specific absorption bands of the gases, are alternately positioned in the radiation path to produce a time-multiplexed signal containing concentration information for all gases. The output from the detector is corrected for gain and offset errors in real-time, utilizing an analog multiplier circuit without the need for demultiplexing.
Another notable patent is the non-dispersive infrared gas analyzer system, which also focuses on measuring HC, CO, and CO₂ concentrations in vehicle exhaust. This system features a sample chamber, a radiation emitter, and a detector similar to his previous invention. It includes a calibration assembly with multiple calibration cells that can be selectively positioned in the radiation path. This allows for an internal calibration standard for two-point calibration of each gas channel. The calibration cells contain predetermined concentrations and pressures of the gas components to compensate for differences in optical path length.
