Publication number: 20230304950Abstract: A system for determining one or more properties of one or more gases. The system comprises sensors configured to measure thermal conductivity and exothermic responses of a sample at multiple temperatures. Sensor responses to exposure to a gas sample at two or more temperatures are compensated and analyzed by a subsystem. The subsystem is configured to determine a thermal conductivity of the gas sample at each of the two or more temperatures and determine at least one component of the gas sample based at least in part on the thermal conductivity value of the sample at each of the two or more temperatures. Related systems and methods of determining one or more properties of a sample are also disclosed.Type: ApplicationFiled: June 1, 2023Publication date: September 28, 2023Inventors: Benjamin S.

Patent number: 10453321Abstract: A pre-smoke detector and system for use in early detection of developing fires whereby vapors of marker chemicals generated during the melting and/or smoldering of common household materials are detected before detection by conventional smoke detectors. Vapors resulting from heating and resultant vaporization of substances are detected as well as vapors resulting from their breakdown, decomposition, or pyrolysis during the pre-combustion stage. Conventional smoke detectors focus on particle detection and are most effective after a developing fire has produced smoke. To minimize false alarms caused by common household odors, the pre-smoke detectors focus on detecting medium temperature pyrolysis products using sensor coatings that can be consistent with a 10-year operational lifetime and multiple orthogonal detection processes.Type: GrantFiled: February 7, 2018Date of Patent: October 22, 2019Assignee: Nevada Nanotech Systems Inc.Inventors: Jesse D.

Patent number: 7557596Abstract: One embodiment of the present invention concerns a test assembly for testing product circuitry of a product die. In one embodiment, the test assembly includes at test die and an interconnection substrate for electrically coupling the test die to a host controller that communicates with the test die. The test die may be designed according to a design methodology that includes the step of concurrently designing test circuitry and a product circuitry in a unified design. The test circuitry can be designed to provide a high degree of fault coverage for the corresponding product circuitry generally without regard to the amount of silicon area that will be required by the test circuitry. The design methodology then partitions the unified design into the test die and the product die. The test die includes the test circuitry and the product die includes the product circuitry. The product and test die may then be fabricated on separate semiconductor wafers.Type: GrantFiled: November 30, 2004Date of Patent: July 7, 2009Assignee: FormFactor, Inc.Inventors: Benjamin N.

Patent number: 7053637Abstract: Signal paths within an interconnect structure linking input/output (I/O) ports of an integrated circuit (IC) tester and test points of an IC die on a wafer are tested for continuity, shorts and resistance by using the interconnect structure to access a similar arrangement of test points on a reference wafer. Conductors in the reference wafer interconnect groups of test points. The tester may then test the continuity of signal paths through the interconnect structure by sending test signals between pairs of its ports through those signal paths and the interconnecting conductors within the reference wafer. A parametric test unit within the tester can also determine impedances of the signal paths through the interconnect structure by comparing magnitudes of voltage drops across pairs of its I/O ports to magnitudes of currents it transmits between the I/O port pairs.Type: GrantFiled: January 12, 2004Date of Patent: May 30, 2006Assignee: FormFactor, Inc.Inventors: Ralph G.
