Publication number: 20170024594Abstract: A method for deconvolution of digital images includes obtaining a degraded image from a digital sensor, a processor accepting output from the digital sensor and recognizing a distorted element within the image. The distorted element is compared with a true shape of the element to produce a degrading function. The degrading function is deconvolved from at least a portion of the image to improve image quality of the image. A method of indirectly decoding a barcode includes obtaining an image of a barcode using an optical sensor in a mobile computing device, the image comprising barcode marks and a textual character. The textual character is optically recognized and an image degrading characteristic is identified from the textual character. Compensating for the image degrading characteristic renders previously undecodable barcode marks decodable. A system for deconvolution of digital images is also included.Type: ApplicationFiled: October 3, 2016Publication date: January 26, 2017Applicant: International Business Machines CorporationInventors: Varun Bhagwan, Timothy Liu, Justin Ormont, Heather Underwood

Publication number: 20160036856Abstract: This disclosure makes public a data flow forwarding method and device, and in this method, a second health state is acquired based on the first health state of one or more pieces of identifying information of the received data flow, wherein the first health state and second health state are associated with the access rights of the user and/or user device that sent the data flow; it employs firewall policy property sets to determine whether or not to forward the data flow, wherein the firewall policy property sets comprise: the second health state. The technical schemes based on this disclosure improve the ability of a firewall to identify network attacks or abnormal activities and reduce administration costs.Type: ApplicationFiled: July 31, 2014Publication date: February 4, 2016Applicant: HILLSTONE NETWORKS, CORP.Inventors: Timothy Liu, Zhong Wang, Lingling Zhang, Bin Jia

Patent number: 9182340Abstract: An optical measuring apparatus comprising at least one light emitting unit, a stage, at least one lens, and at least one light detector is provided. The light emitting unit emits a light beam. The stage contains accommodating spaces. The accommodating spaces move to the transmission path of the light beam in turn. The lens is located between the light emitting unit and the stage, whose orthogonal projection on the stage appears substantially to be a polygon. When one of the accommodating spaces moves to the transmission path of the light beam, a perpendicular bisector half line of each side of the polygon is not overlapped with another adjacent accommodating space of the accommodating spaces. An optical measuring method is also provided.Type: GrantFiled: April 10, 2013Date of Patent: November 10, 2015Assignee: Lite-On Technology CorporationInventors: Yu-Jin Kao, Yi-Kai Cheng, Shih-Chang Wang, Ta-Hsiang Wang, Timothy Liu

Patent number: 8505823Abstract: A method for noise removal from color barcode images includes acquiring a barcode image using a color imaging array and separating the barcode image into color channels. Weighting factors are associated with the color channels and at least one weighting factor is reduced. The weighting factors are applied to the color channels to produce a first transformed image. A portion of the first transformed image is analyzed to produce a first set of decoded data from the barcode.Type: GrantFiled: June 30, 2010Date of Patent: August 13, 2013Assignee: International Business Machine CorporationInventors: Varun Bhagwan, Timothy Liu, Justin Ormont, Heather Underwood

Patent number: 8001610Abstract: An endpoint defense system uses endpoint health indicators and user identity information to provide fine-grain access control over network resources. For example, the endpoint defense system may include a controller, a set of protection devices, and a set of agents. The agents are software applications installed on a set of endpoints to gather the health information that represents security states of the endpoint devices. The agents send updated health information to the controller. In response to a login attempt, the controller processes the health indicators and identity information through a set of administrator-defined policies to generate a set of access rights. The controller transfers the set of access rights to the protection devices. The protection devices then control user access to network resources according to the set of access rights. The controller sends updated sets of access rights to the protection devices whenever the access rights change.Type: GrantFiled: September 28, 2005Date of Patent: August 16, 2011Assignee: Juniper Networks, Inc.Inventors: Roger Chickering, Sampath Srinivas, Timothy Liu

Publication number: 20110014617Abstract: Methods and kits for detecting a target nucleic acid in a sample are described. In some embodiments, the sample to be analyzed includes a primer which hybridizes to at least a portion of the target nucleic acid, a probe having a first region which hybridizes to at least a portion of the target nucleic acid and a second region having a detectable label, a polymerase which extends the hybridized primer and an enzyme comprising nuclease activity that can cleave the hybridized hybridization probe to thereby release a labeled probe fragment. In some embodiments, the sample can then be contacted with a solid support comprising surface bound capture probes which can hybridize to the labeled probe fragment(s). These capture probes more readily bind to the probe fragment(s) than to the intact hybridization probe. The label can then be detected on the support surface. In this manner, improved discrimination between the probe fragments and the intact hybridization probes can be achieved.Type: ApplicationFiled: June 15, 2010Publication date: January 20, 2011Applicant: LIFE TECHNOLOGIES CORPORATIONInventors: Kristian Scaboo, Vissarion Aivazachvili, Timothy Liu, Robert Eason, Konrad Faulstich
