Patent number: 11959683Abstract: A modulating refrigeration system includes an evaporation unit and a condensing unit. The evaporation unit generates a first output airflow comprising a lower temperature, a lower relative humidity, or both than a first supply airflow and directs the first output airflow into a building. The condensing unit generates a second output airflow at a higher temperature than a second supply airflow and discharges the second output airflow to an unconditioned space. The evaporation unit comprises a first valve operable to direct a portion of refrigerant to a secondary evaporator and primary evaporator or to direct the entire flow of refrigerant to the primary evaporator and bypassing the secondary evaporator.Type: GrantFiled: January 26, 2022Date of Patent: April 16, 2024Assignee: THERMA-STOR LLCInventors: Grant M. Lorang, Gustavo Daniel Olivera, Weizhong Yu, David Treleven, Todd R. DeMonte, Robert John Motiff, Timothy S. O'Brien

Publication number: 20210251614Abstract: An instrument for collecting tissue from a body cavity includes a hollow tubular body having a tubular wall. The hollow tubular body can collect material from a body cavity in a coring mode or an aspiration mode. The tubular wall defines a passage that extends from a proximal end portion of the tubular body to a distal end portion of the tubular body. A middle section of the tubular body includes an articulating section that allows the middle section to articulate relative to the proximal end portion. The distal end portion includes at least one suction port extending from an outer wall surface to an inner wall surface of the tubular wall. The suction port provides a path of fluid communication between the outer wall surface and the passage for drawing in tissue from a body cavity when the tubular body is connected to a source of negative pressure.Type: ApplicationFiled: May 3, 2021Publication date: August 19, 2021Applicant: Lenkbar, LLCInventors: Erik H. Papenfuss, Timothy M. O'Brien, Robert E. Marx

Patent number: 10615888Abstract: Disclosed is a passive intermodulation (PIM) test system having a pulsed signal generator configured to generate and apply a pulsed stimulus signal to a device under test. The PIM test system is further configured to measure a power of at least one PIM product generated by a PIM source in the device under test using the pulsed stimulus signal. Also disclosed in a method for evaluating PIM in a device under test, the method includes using a pulsed stimulus signal to measure a power of at least one PIM product generated by a PIM source in the device under test.Type: GrantFiled: June 14, 2016Date of Patent: April 7, 2020Assignee: BIRD TECHNOLOGIES GROUP INC.Inventors: Timothy L. Holt, Timothy M. O'Brien

Patent number: 5595545Abstract: A golf swing training apparatus having a circular track is made by bending an elongate X-section extrusion of an aluminum alloy to form a plurality of partial circular track sections, which are then joined end-to-end to form a full 360.degree. circular hoop. A multi-wheeled club guide cart rides on the track with a V-shaped circumference of each wheel mated to radially inner and outer opposed corner edges of the track member. The golf club includes a shaft of uniform diameter that rotates and slides in a linear bearing that in turn is connected by a pivot to the cart that allows rotation of the linear bearing and pivoting of the bearing for free movement of the golf club shaft in a plane orthogonal to that of the hoop throughout the swing.Type: GrantFiled: October 3, 1995Date of Patent: January 21, 1997Assignee: Track Trainer, Inc.Inventor: Timothy M.
