Patent number: 10956227Abstract: Examples provide two-tiered scheduling within a cluster. A coarse-grained analysis is performed on a candidate set of hosts to select a host for a virtual computing instance based on optimization of at least one resource. A host is selected based on the analysis results. The identified virtual computing instance is placed on the selected host. A fine-grained analysis is performed on a set of communication graphs for a plurality of virtual computing instances to generate a set of penalty scores. A set of communicating virtual computing instances are selected based on the set of penalty scores. A first virtual computing instance from a first host is relocated to a second host to minimize a distance between the first virtual computing instance and a second virtual computing instance. Relocating the first virtual computing instance reduces at least one penalty score for the set of communicating virtual computing instances.Type: GrantFiled: February 11, 2019Date of Patent: March 23, 2021Assignee: VMware, Inc.Inventors: Po-An Tsai, Sahan Gamage, Rean Griffith

Patent number: 10915718Abstract: A radio frequency (RF) positioning system comprises transceivers, positioning tags, processing units and a computing host. One or multiple positioning tags are attached to a target object being located. When the transceivers first generate and transmit transmission signals, one or multiple tag antennas in the positioning tag receive the transmission signals and transmit back modulated signals. The transceivers then receive and transmit the modulated signals to the processing units. The processing units are configured to obtain received signals, and calculate frequency differences based on the received signals and the transmission signals. The computing host calculates position coordinates of tag antennas based on the frequency differences, and then calculates the orientation of the target object being located according to the position coordinates of the tag antennas.Type: GrantFiled: December 21, 2018Date of Patent: February 9, 2021Assignee: METAL INDUSTRIES RESEARCH & DEVELOPMENT CENTREInventors: Nai-Chun An, Yuan-Chih Lin, Hsiu-An Tsai, Shuo-Ching Chen, Chih-Lung Lin
