Carbon monoxide detector

Portable radiotelephone unit

An instrument for use on a marine vehicle including a sensor for determining the concentration of carbon monoxide (COC) present on the vehicle, an LED indicator for visually displaying the concentration, a microprocessor using a mathematical formula for calculating the health hazard to a person on the vehicle occasioned by the level of carbon monoxhemoglobin %COHb in the blood of that person resulting from breathing concentrations of carbon monoxide over a period of time. The instrument also determines for determining the health hazard condition in terms of long term exposure to a low COC level, moderate term exposure to a moderate COC level, and short term exposure to a high COC level, and in addition visually and audibly indicates the health hazard conditions. A method for the operating instrument, and a method of testing operativeness of the instrument are also provided.

Carbon monoxide health hazard monitor

A computer system is proposed for finding and displaying the depth and depth related values of an object in an aquatic environment in which and LCD display is subdivided into segments each representing a fraction of the total depth range in which the system is operating as well as a fraction of the transit time for the transmission of pulses within the depth range. Each segment is addressed and activated in response to the presence of a receiver output in the microprocessor for a given number of consecutive time-scans, thus providing a quasi-analog visual display of depth on the array of the segmented scale.
