Patent number: 11966418Abstract: Systems and methods are provided for adaptive data replication. A first data object is stored. One or more first network characteristics of a communication network are detected. A first replication mode is triggered (e.g., a single-master replication mode) based on the one or more first network characteristics of the communication network. The single-master replication may be configured to facilitate real-time synchronizations (e.g., for critical updates). One or more second network characteristics of the communication network are detected. A second replication mode (e.g., a multi-master replication mode) is triggered based on the one or more second network characteristics. The second replication may be configured to facilitate a delayed synchronization (e.g., for non-critical updates) of the first data object and the second data object using the second update file.Type: GrantFiled: March 8, 2023Date of Patent: April 23, 2024Assignee: Palantir Technologies Inc.Inventors: Peter Wilczynski, Ryan Zheng, John Carrino, Timothy Wilson, Stephen Freiberg, John Garrod, William Waldrep

Patent number: 11952116Abstract: Described herein are systems for roof scan using an unmanned aerial vehicle. For example, some methods include capturing, using an unmanned aerial vehicle, an overview image of a roof of a building from above the roof; presenting a suggested bounding polygon overlaid on the overview image to a user; determining a bounding polygon based on the suggested bounding polygon and user edits; based on the bounding polygon, determining a flight path including a sequence of poses of the unmanned aerial vehicle with respective fields of view at a fixed height that collectively cover the bounding polygon; fly the unmanned aerial vehicle to a sequence of scan poses with horizontal positions matching respective poses of the flight path and vertical positions determined to maintain a consistent distance above the roof; and scanning the roof from the sequence of scan poses to generate a three-dimensional map of the roof.Type: GrantFiled: August 18, 2022Date of Patent: April 9, 2024Assignee: Skydio, Inc.Inventors: Peter Henry, Jack Zhu, Brian Richman, Harrison Zheng, Hayk Martirosyan, Matthew Donahoe, Abraham Galton Bachrach, Adam Bry

Patent number: 11940795Abstract: In some examples, an unmanned aerial vehicle (UAV) may include one or more processors configured to capture, with one or more image sensors, and while the UAV is in flight, a plurality of images of a target. The one or more processors may compare a first image of the plurality of images with a second image of the plurality of images to determine a difference between a current frame of reference position for the UAV and an estimate of an actual frame of reference position for the UAV. In addition, the one or more processors may determine, based at least on the difference, and while the UAV is in flight, an update to a three-dimensional model of the target.Type: GrantFiled: January 20, 2023Date of Patent: March 26, 2024Assignee: SKYDIO, INC.Inventors: Peter Henry, Jack Zhu, Brian Richman, Harrison Zheng, Hayk Martirosyan, Matthew Donahoe, Abraham Bachrach, Adam Bry, Ryan David Kennedy, Himel Mondal, Quentin Allen Wah Yen Delepine

Patent number: 10488100Abstract: Methods, apparatus, and systems for load control for cooling systems are provided. Coolant flows through a plurality of cooling units in a cooling system. The coolant flow is halted for each cooling unit that is undergoing a defrost cycle. Each cooling unit is configured to start a first defrost cycle at a random time within a predetermined time range after the cooling unit is started or powered on. After the first random start defrost cycle, a regular periodic defrost cycle may be maintained. Thus, the cooling units may be powered on simultaneously while still providing desynchronized defrost cycles, enabling the cooling system to maintain adequate coolant flow and heat load to avoid deleterious stop and restart cycles.Type: GrantFiled: November 9, 2016Date of Patent: November 26, 2019Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Benjamin Tang, Randy Brunter, Peter Zheng

Patent number: 9062900Abstract: A space-saving cooling system for an aircraft may include an evaporator in an enclosure with an accumulation region in the enclosure for a liquid mixture of liquid refrigerant and lubricating oil. Space saving may be achieved through a combining of evaporator functions and accumulator functions in a single enclosure. A heat exchanger may be interposed between the evaporator and the compressor for heating refrigerant emerging from the evaporator so that liquid refrigerant does not reach an inlet of the compressor.Type: GrantFiled: November 8, 2010Date of Patent: June 23, 2015Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Ranjit Darke, Peter Zheng, Ricky Gov

Patent number: 8882158Abstract: A connection system for carrying a refrigerant may provide a hybrid redundancy in sealing a refrigerant flow from the surround system environment. The connection system may include a first sealing ring of a first type and a second sealing ring of a second type positioned downstream from the first sealing ring. In some embodiments, the first sealing ring may be in a groove positioned around the outside diameter of a male fitting. The second sealing ring may be positioned at an interface between the male fitting and a female fitting. In some embodiments, flanges of each fitting define the interface so that the second sealing ring may be positioned between the flanges of each fitting. The second sealing ring may be selected from a material that has a wider range of operating temperature than the first sealing ring so that in the event of failure in the first sealing ring, the second sealing ring may prevent leakage.Type: GrantFiled: January 24, 2013Date of Patent: November 11, 2014Assignee: Honeywell International Inc.Inventors: Ricky G. Gov, Peter Zheng, Ray Molina

Patent number: 8596089Abstract: A refrigerant distribution system has a plurality of chambers formed inside a refrigerant distribution plate, each of the plurality of chambers extending from one end of the refrigerant distribution plate into the refrigerant distribution plate; and a plurality of holes formed in each of the plurality of chambers, the plurality of holes fluidly communicating each of the plurality of chambers with an outside of the refrigerant distribution place. The evaporator may be oriented such that the refrigerant flows horizontally with respect to gravity. The present invention may improve the thermal performance of the evaporator while the evaporator is oriented sub-optimally. Often, with horizontal flow through an evaporator, the refrigerant phases, liquid and vapor, may separate in the manifold, resulting in poor distribution of refrigerant in the evaporator core. The refrigerant distribution plate of the present invention evenly distributes the refrigerant in the core.Type: GrantFiled: February 26, 2009Date of Patent: December 3, 2013Assignee: Honeywell International Inc.Inventors: Ranjit Darke, Peter Zheng
