Publication number: 20140049661Abstract: Technologies are generally described herein for generating a higher resolution still frame. Some example technologies may configure a video camera at a first configuration, which the video camera to capture video at a first pixel offset. The technologies may capture a first frame of al field-of-view through the video camera configured at the first configuration. The first flame may contain the field-of-view captured at the first pixel offset. The technologies may adjust the video camera from the first configuration to a second configuration, which adapts the video camera to capture the video at a second pixel offset, the adjustment using a hardware mechanism. The technologies may capture a second frame of the field-of-view through the video camera configured at the second configuration. The second frame may contain the field-of-view captured at the second pixel offset.Type: ApplicationFiled: May 6, 2011Publication date: February 20, 2014Inventors: Henry Leung, Xiaoxiang Liu

Publication number: 20140047106Abstract: Technologies are presented for implementing a compressive-sensing-based data collection system in a cloud environment. In some examples, high-dimensional sensor data may be compressed using sparsity transforms and compressive sampling. The resulting low-dimensional data messages may be steered through a switch network to a cloud service manager, which then reconstructs the compressed messages for subsequent analysis, reporting, and/or comparable actions.Type: ApplicationFiled: August 8, 2012Publication date: February 13, 2014Inventors: Henry Leung, Xiaoxiang Liu

Patent number: 8610771Abstract: Technologies are generally described for a broadband passive sensing and tracking system that may employ a number of passive receivers that each have the capability of sensing electromagnetic waves (e.g., Radio Frequency “RF” signals) from surrounding broadcast sources. Each passive receiver may be adapted to sense through one or more antennas. Multiple receivers at different positions may be utilized to form a broadband sensing network adapted to perform collaborative tracking of a scene of interest. According to some examples, a beam-forming algorithm may be applied over the broadband sensing network utilizing an antenna array formed by the passive receivers to localize and track objects.Type: GrantFiled: March 8, 2010Date of Patent: December 17, 2013Assignee: Empire Technology Development LLCInventors: Henry Leung, Xiaoxiang Liu
