Patent number: 11609225Abstract: Electrochemical sensors commonly used in breath alcohol testing devices detect a concentration of alcohol in a sample of fluid. The sample of fluid is introduced into the electrochemical sensor and a current is generated by the oxidation of the alcohol within the fluid. The electrical output from the electrochemical sensor, plotted over time, forms an output curve, which may be used to estimate the concentration of alcohol in the fluid sample. The technology disclosed herein includes various methods for determining the quantity of an electrochemically convertible substance in a fluid sample using a breath alcohol content device, including detecting water saturation level of the fluid sample. The disclosed technology involves measuring electrochemical sensor outputs to quantify alcohol content of the fluid sample.Type: GrantFiled: January 9, 2020Date of Patent: March 21, 2023Assignee: LIFELOC TECHNOLOGIES, INC.Inventors: Wayne Robert Willkomm, Mark Anthony Lary

Patent number: 9623138Abstract: Implementations disclosed herein provide systems and methods of automatically sterilizing a portable electronic device with ultraviolet (UV) radiation. In one implementation, the method includes distributing UV light substantially uniformly across an intended surface of a device in an enclosure, and sterilizing the intended surface using a calculated dosage of the UV light. In another implementation, an electronic device sterilization system includes an enclosure configured to selectively receive a device for sterilization using a calculated dosage of light, wherein the enclosure includes one or more LEDs, a first reflector configured to receive and reflect the light from the LEDs, and a second reflector configured to receive the light reflected from the first reflector and distribute the light uniformly onto an intended planar surface of the device.Type: GrantFiled: August 17, 2015Date of Patent: April 18, 2017Assignees: Lifeloc Technologies, Inc., AquiSense Technologies LLCInventors: Jennifer Godwin Pagan, Edward Brittain Stokes, John Robert Krause, Paolo Batoni, Gurumurthi Ravishankar, Kelly Silverman

Patent number: 6795775Abstract: A method for determining the quantity and identity of an electrochemically convertible substance in a gas sample. The substance is converted in an electrochemical sensor producing an electrical output. The characteristic parameters of a curve-defining equation y(t)=k×(e−axt−e−bxt) are calculated based on three measurements of output at times t, 2t and 4t. The integral under all or part of the curve is calculated to determine the quantity of the substance. The equation parameters are compared with standard values to determine the identity of the substance.Type: GrantFiled: July 21, 2003Date of Patent: September 21, 2004Assignee: Lifeloc Technologies, Inc.Inventor: Frank A. Traylor, III
