Patent number: 11956380Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for receiving, from one of two or more sensors of a device that independently determine whether an aircraft takeoff has likely occurred, an indication that the aircraft takeoff has likely occurred; activating, based on receiving the indication that the aircraft takeoff has likely occurred, an airplane mode of the device; receiving, while the device is in the airplane mode and from one of two or more other sensors of the device that independently determine that an aircraft flight is likely not occurring, an indication that the aircraft flight is likely not occurring; and deactivating, based on receiving the indication that the aircraft flight is likely not occurring, the airplane mode of the device. The indication that the aircraft takeoff has likely occurred may include acceleration data indicating an acceleration of the device in three dimensions.Type: GrantFiled: October 25, 2021Date of Patent: April 9, 2024Assignee: X Development LLCInventors: Erich Karl Nachbar, Grant Alexander Uy, Carl Turner

Patent number: 11902858Abstract: The technology enables locating asset tracking tags based on a ramped sequence of signals from one or more beacon tracking tags. The sequence includes at least one minimum power signal and at least one maximum power signal. Each signal in the sequence has a tag identifier and an initial signal strength value. Each beacon signal in the ramped sequence is associated with the time at which that beacon signal was received by a reader. Each beacon signal is also associated with a received signal strength at reception. A location of the beacon tracking tag is estimated according to the signals in the sequence based on the difference between the initial and received signal strengths. A position of the reader device is identified based on the beacon tag's location. An asset tracking tag location is identified based on the reader's location and packets received by the reader from the asset tag.Type: GrantFiled: April 22, 2022Date of Patent: February 13, 2024Assignee: X DEVELOPMENT LLCInventors: David Andre, Erich Karl Nachbar

Publication number: 20230394257Abstract: The technology enables locating asset tracking tags based on one or more beacon signals from at least one anchor beacon. Each of the beacon signals including anchor beacon identification information and being associated with a received signal strength upon receipt at a reader device. The anchor beacon identification information being associated with a physical location of the anchor beacon. A position of the reader device is estimated according to the received signal strength of the one or more beacon signals and the physical location of the at least one anchor beacon from the anchor beacon identification information. One or more signals from an asset tracking tag are detected by the reader device. A location of the asset tracking tag is identified based on the estimated position of the reader device and signal strength information for each of the one or more detected signals from the asset tracking tag.Type: ApplicationFiled: June 2, 2022Publication date: December 7, 2023Inventors: David Andre, Erich Karl Nachbar

Patent number: 10429914Abstract: Multi-level data center using consolidated power control is disclosed. One or more controllers communicate with one or more power supplies and sensors to adapt to dynamic load requirements and to distribute DC-power efficiently across multiple IT racks. The distributed DC-power includes one or more DC-voltages. Batteries can be temporarily switched into a power supply circuit to supplement the power supply during spikes in power load demand while a controller reconfigures power supplies to meet the new demand. One or more DC-to-AC converters handle legacy power loads. The DC-to-AC converters are modular and are paralleled for redundancy. The DC-to-AC converters are sourced from the one or more AC-to-DC converters. The AC power is synchronized for correct power flow control. The one or more controllers communicate with the one or more AC-power supplies to dynamically allocate AC-power from the DC-to-AC converters to the multiple legacy IT racks.Type: GrantFiled: October 20, 2017Date of Patent: October 1, 2019Assignee: Virtual Power Systems, Inc.Inventors: Karimulla Raja Shaikh, Ravi Subramaniam, Denis Kouroussis, Rajeev P Huralikoppi, Ryan Justin Kennedy, Erich Karl Nachbar, Shankar Ramamurthy, Pranthik Samal, Rajaram Soundararajan, Andrew Sy

Patent number: 10128684Abstract: Disclosed are systems and methods to provide energy control via power-requirement analysis and power-source enablement. Both demand-side and supply-side techniques are used alone or in conjunction to determine an optimal number of power sources to supply power to one or more loads. When fluctuations in power requirements are present, measures such as decoupling less-critical loads in order to continue delivering power to critical systems and turning on and off power sources as needed to meet the current power demands of a system are implemented. Power sources are periodically deactivated by the system on a rotational basis such that all power sources wear evenly, prolonging the life of the equipment. A scalable architecture that allows the virtualization of power from the underlying hardware form factor is also provided.Type: GrantFiled: October 28, 2014Date of Patent: November 13, 2018Assignee: Virtual Power Systems, Inc.Inventors: Shankar Ramamurthy, Sushant Shankar, Rajaram Soundararajan, Andrew Sy, Andrew L Wang, Erich Karl Nachbar, K David Lin, Frank Chuang, Rajeev P Huralikoppi, Ryan Justin Kennedy, Denis Kouroussis, Milind Kukanur, Pranthik Samal
