Patent number: 10890523Abstract: An optical spectrometer module for analysing samples. The optical spectrometer module comprises two or more sample holders. Each sample holder is adapted to receive and reproducibly position a sample in fixed locations within the optical spectrometer module. Each sample holder is also adapted to receive a light beam to thereby enable a sample contained in the sample holder to be exposed to the received light beam. Each sample holder is further adapted to enable light transmitted through the sample holder to exit the sample holder. The optical spectrometer module also comprises two or more electro-thermal components. Each electro-thermal component is thermally coupled to a respective sample holder to control the temperature of the sample holder.Type: GrantFiled: January 16, 2018Date of Patent: January 12, 2021Assignee: AGILENT TECHNOLOGIES, INC.Inventor: Hugh Charles Stevenson

Patent number: 10830464Abstract: A fresh-air cooling system for a building structure having an unvented attic is provided. The system provides airflow pathways that allow outside air to be drawn through, and discharged from, a building having an unvented attic. Dampers with a low thermal conductivity regulate airflow through the building structure. The system allows a whole house fan to cool a building having an unvented attic. The system seals or otherwise alters airflow pathways through the building structure in order to reduce heat transfer between the building and the outside environment when the cooling system is not in use.Type: GrantFiled: March 7, 2016Date of Patent: November 10, 2020Assignee: QC MANUFACTURING, INC.Inventor: Dana Charles Stevenson

Patent number: 10753627Abstract: An energy efficient and quiet air cooling system for a building structure is provided. The air cooling system includes an evaporator system mounted in the wall of the building, a remotely mounted fan, an air intake, and a sound and heat insulating duct. The fan is mounted in the attic and configured to draw air from the living area of the building through the sound insulating duct with sufficient power to create a negative static pressure in the living area. The negative static pressure in turn causes outside air to flow through the evaporator system which removes heat from the outside air. The cooled air is in turn drawn into the building and pulled into the attic through the duct and expelled through the attic. The fan expels warm air into the attic, creating a positive pressure environment which causes the warm air to be expelled from the attic through natural vents.Type: GrantFiled: January 14, 2019Date of Patent: August 25, 2020Assignee: QC MANUFACTURING, INC.Inventor: Dana Charles Stevenson
