Publication number: 20190340317Abstract: Systems and methods are disclosed for using a synthetic world interface to model environments, sensors, and platforms, such as for computer vision sensor platform design. Digital models may be passed through a simulation service to generate synthetic experiment data. Systematic sweeps of parameters for various components of the sensor or platform design under test, under multiple environmental conditions, can facilitate time- and cost-efficient engineering efforts by revealing parameter sensitivities and environmental effects for multiple proposed configurations. Searches through the generated synthetic experimental data results can permit rapid identification of desirable design configuration candidates.Type: ApplicationFiled: May 7, 2018Publication date: November 7, 2019Inventors: Jonathan Chi Hang CHAN, Michael EBSTYNE, Alex A.

Patent number: 8930900Abstract: A method for building an application installation repository is disclosed herein. In one embodiment a build directory comprising a plurality of application objects is evaluated. Artifact generation rules may also be evaluated with respect to the application objects and the build directory. Object groupings, each comprising one or more application objects of the plurality of application objects, are defined according to the evaluations of the artifact generation rules and the hierarchical directory structure and artifacts are generated according to the object groupings. An installable application is generated that includes the generated artifacts. Artifacts may be further grouped into sharable units and assemblies according to rules and organization of application objects in the build directory. A delta build including only artifacts corresponding to modified files and correspondingly modified metadata may also be generated according to methods disclosed herein.Type: GrantFiled: March 15, 2013Date of Patent: January 6, 2015Assignee: International Business Machines CorporationInventors: Keith Chi-Hang Chan, Yu Yuan

Patent number: 8829942Abstract: A comparator is provided and the comparator includes a comparing input unit and a latching unit. Wherein, the comparing input unit has a first input receiving a first comparing signal and has a second input receiving a second comparing signal. The comparing input unit drives a first intermediate node signal at a first intermediate node depending on the first comparing signal according to a first strobe signal, and the comparing input unit drives a second intermediate node signal at a second intermediate node depending on the second comparing signal according to the first strobe signal. The latching unit determines a comparing result according to at least one of the first intermediate node signal and the second intermediate node signal. In addition, the latching unit latches the comparing result according to a second strobe signal.Type: GrantFiled: November 13, 2012Date of Patent: September 9, 2014Assignee: University of MacauInventors: Chi-Hang Chan, Yan Zhu, U-Fat Chio, Sai-Weng Sin, Seng-Pan U, Rui Paulo da Silva Martins

Patent number: 8659461Abstract: The present invention provides a pipelined-successive approximation register (SAR) analog-to-digital converter (ADC) circuit with decoupled flip-around MDAC, capacitive attenuation solution and self-embedded offset cancellation. The flip-around MDAC architecture is built for low inter-stage gain implementation. A capacitive attenuation solution is provided for minimizing the power dissipation and optimizing conversion speed. The design reuses SAR ADC to perform offset cancellation, which significantly saves calibration area, power and time.Type: GrantFiled: November 13, 2012Date of Patent: February 25, 2014Assignee: University of MacauInventors: Yan Zhu, Chi-Hang Chan, Sai-Weng Sin, Seng-Pan U, Rui Paulo da Silva Martins, Franco Maloberti
