Patent number: 11722377Abstract: A control device may be configured to form a network at a unique coordinated startup time. The control device may identify a role assigned to the control device in a previously-formed network that the control device was attached to. The control device may determine a unique coordinated startup time for the control device based on the role assigned to the control device in the previously-formed network. The control device may initiate a network formation procedure at the unique coordinated startup time for the device. For example, the network formation procedure may cause the control device to attach to another control device in the network. The network formation procedure is configured to enable the control device to assume the role assigned to the control device in the previously-formed network in the new network.Type: GrantFiled: June 20, 2020Date of Patent: August 8, 2023Assignee: Lutron Technology Company LLCInventors: Jeffrey S.

Patent number: 9091597Abstract: Particles of a flow of aerosol are collected and analyzed by passing them through a housing having an inlet area, an outlet area, and a collection and analysis area. A collection electrode has a tip disposed in the flow path in the collection and analysis area. Particles are collected on the tip of the collection electrode. A microwave pulse is applied to the collection and analysis area such that a plasma is created. Atomic emissions produced during at least part of the microwave step are collected for analysis of the ablated particles.Type: GrantFiled: March 14, 2013Date of Patent: July 28, 2015Assignee: The United States of America, as represented by the Secretary of the Department of Health and Human Services, Centers for Disease Control and PreventionInventors: Pramod Kulkarni, Philip Efthimion

Patent number: 6861036Abstract: An improved method for charging ultrafine particles in coronas (e.g., unipolar or bipolar corona discharges) by exposing the particles to X-ray irradiation. Experimental tests have verified that positive corona in the presence of X-ray irradiation results in maximum or optimum charging efficiency, followed by a negative corona in the presence of X-ray irradiation, X-ray radiation only (without corona), negative corona only (without X-ray irradiation), and finally positive corona only (without X-ray irradiation). This method and system is particularly well suited for use with bioaerosol particles wherein exposure to the corona discharge and X-ray irradiation serves to both capture and inactivate the bioaerosol particles using a single device.Type: GrantFiled: August 30, 2002Date of Patent: March 1, 2005Assignee: Washington University in St. LouisInventors: Pratim Biswas, Norikazu Namiki, Pramod Kulkarni
