Patent number: 10161685Abstract: Embodiments of a heat exchanger, e.g. a micro-channel heat exchanger are disclosed. The heat exchanger may include a plurality of rows of micro-channel tubes, each of which can be configured to direct a working fluid in a specific direction. The heat exchanger may include one or more distributors in a distribution header of the heat exchanger, each of which can be connected to a different application circuit (e.g. a refrigeration circuit) so that a capacity of the heat exchanger may be regulated. The heat exchanger as disclosed herein can be used as an evaporator and/or a condenser in a refrigeration system.Type: GrantFiled: January 11, 2016Date of Patent: December 25, 2018Assignee: TRANE INTERNATIONAL INC.Inventors: Roger J. Voorhis, Jr., Jun Wang, Brian Westfall, Sean A. Smith, Tao Zhou, William B. Fox, Felix Quintero, Michael W. Groen, Justin S. Winters, Robert F. Schult

Patent number: 8387499Abstract: A method for automatically cutting a workpiece comprising the steps of moving a workpiece along its longitudinal axis, positioning a cutting blade by rotating the blade about a vertical axis, positioning the cutting blade by rotating about a bevel axis, and vertically moving the blade into cutting contact with the workpiece, thereby stab cutting the workpiece and creating a bevel cut. The method may also comprise moving the blade along a transverse axis. Further steps may include moving the cutting blade along a transverse axis simultaneous to moving the workpiece along it longitudinal axis, thereby creating a scarf cut.Type: GrantFiled: April 17, 2012Date of Patent: March 5, 2013Assignee: Illinois Tool Works Inc.Inventors: Brian Westfall, David L. McAdoo, Richard Zeinert, Andrew Lashley, Brent McMillan

Patent number: 6546360Abstract: A system and method for determining when portable devices require service. In one embodiment, the system is co-located with the portable device and includes a sensor, positioning system receiver and communication transmitter. The sensor senses when the portable device requires service. The positioning system receiver receives positioning signals, such as positioning signals issued by the Global Positioning System, (GPS), and uses the positioning system signals to determine the location of the portable device. The communications transmitter transmits a service signal to a service base station to indicate that the portable device requires service. The service signal includes the determined location of the portable device, thereby eliminating the need for service personnel to physically inspect every portable device in order to determine if any portable devices require service.Type: GrantFiled: October 30, 1998Date of Patent: April 8, 2003Assignee: Trimble Navigation LimitedInventors: Charles Gilbert, Brian Westfall

Patent number: 5515057Abstract: Apparatus and method for eliminating the time delay variation associated with the satellite signal propagating within an antenna for a GPS receiver (or GLONASS receiver). The antenna is an n-point symmetrical feed double-frequency feed antenna which has the reduced electrical center error ellipsoid as compared with the single point antenna. The angular dependence of the time delay variation on the azimuth and the angle of elevation of the incoming satellite signal is reduced in case of n-feed point symmetrical antenna. The GPS receiver with n-point antenna can be used for differential GPS, both static and dynamic, and for absolute GPS positioning.Type: GrantFiled: September 6, 1994Date of Patent: May 7, 1996Assignee: Trimble Navigation LimitedInventors: Gary R. Lennen, Wilfred Hand, Brian Westfall

Patent number: 5465413Abstract: Method and apparatus for reducing or cancelling impulse noise from a signal containing noise. The desired noise-free signal is assumed to have a representative frequency .omega..sub.3, but may have a range of frequencies adjacent to this frequency, and is assumed to have substantially zero amplitude for all frequencies .omega.<.omega..sub.1 and/or for all frequencies .omega.>.omega..sub.2, where .omega..sub.1 <.omega..sub.3 <.omega..sub.2 or .omega..sub.1 <.omega..sub.2. An input (noisy) signal is filtered and analyzed in a narrow frequency region surrounding .omega.=.omega..sub.1 and/or a narrow frequency region surrounding .omega.=.omega..sub.2 to obtain one or two output signal components n.sub.1 (t) and/or n.sub.2 (t), respectively, that, ideally, contain no contribution from the desired signal. The input signal is also filtered and analyzed in a narrow frequency region surrounding .omega.=.omega..sub.3 to obtain an output signal s(t)+n.sub.3 (t) component including the desired signal s(t).Type: GrantFiled: March 5, 1993Date of Patent: November 7, 1995Assignee: Trimble Navigation LimitedInventors: Per Enge, Dominic Farmer, Brian Westfall
