Publication number: 20130139263Abstract: Systems and methods for providing device and/or device type fingerprinting based on properties of network traffic originating from a device to be identified. In one implementation, the method includes capturing packets routed through a network at an intermediate node between the originating device to be identified and destination, measuring properties of the captured traffic, including packet inter-arrival time, and generating a signature based on the measured properties that includes identifying information about the hardware and/or software architecture of the device. Various implementations do not require deep packet inspection, do not require a managed device-side client, are protocol and packet payload agnostic, and effective for MAC or IP-level encrypted streams. Also, various implementations can provide wired-side detection of wireless devices and device types and can detect both previously detected and unknown devices.Type: ApplicationFiled: November 29, 2012Publication date: May 30, 2013Applicant: GEORGIA TECH RESEARCH CORPORATIONInventor: Georgia Tech Research Corporation

Publication number: 20130133346Abstract: The invention is directed toward a vapor-liquid heat and/or mass exchange device that can be used in an integrated heat and/or mass transfer system. To achieve high heat and mass transfer rates, optimal temperature profiles, size reduction and performance increases, appropriately sized flow passages with microscale features, and countercurrent flow configurations between working fluid solution, vapor stream, and/or the coupling fluid in one or more functional sections of the desorber are implemented. In one exemplary embodiment of the present invention, a desorber section utilizes a heating fluid flowing in a generally upward direction and a concentrated solution flowing in a generally downward direction with gravity countercurrent to the rising desorbed vapor stream. To further increase the efficiency of the system, various types of column configurations can be used. Additionally, the surfaces of the microchannels can be altered to better transfer heat.Type: ApplicationFiled: August 10, 2011Publication date: May 30, 2013Applicant: GEORGIA TECH RESEARCH CORPORATIONInventors: Srinivas Garimella, Jared Carpenter Delahanty, Ananda Krishna Nagavarapu

Patent number: 8449174Abstract: Wafer temperature is measured as a function of time following removal of a heat source to which the wafer is exposed. During the wafer temperature measurements, a gas is supplied at a substantially constant pressure at an interface between the wafer and a chuck upon which the wafer is supported. A chuck thermal characterization parameter value corresponding to the applied gas pressure is determined from the measured wafer temperature as a function of time. Wafer temperatures are measured for a number of applied gas pressures to generate a set of chuck thermal characterization parameter values as a function of gas pressure. A thermal calibration curve for the chuck is generated from the set of measured chuck thermal characterization parameter values and the corresponding gas pressures. The thermal calibration curve for the chuck can be used to tune the gas pressure to obtain a particular wafer temperature during a fabrication process.Type: GrantFiled: August 17, 2010Date of Patent: May 28, 2013Assignee: Lam Research CorporationInventors: Keith William Gaff, Neil Martin Paul Benjamin

Patent number: 8452460Abstract: The present invention provides an apparatus for fluidics-based automated orientation of plant embryos. The apparatus comprises flow channels, flow direction means, an orientation detector and a control unit. The orientation of embryos suspended in liquid flowing individually through the flow channels is constrained to cotyledon-first or cotyledon-last orientation by dimensional constraints. The orientation is determined by the orientation detector. Embryos not oriented as desired are directed into a reservoir tube by the flow direction means, after which the flow is directed from the reservoir tube to the outlet thereby having reoriented the embryo. Means of sorting viable embryos from other objects are optionally included in the apparatus.Type: GrantFiled: April 9, 2009Date of Patent: May 28, 2013Assignee: Georgia Tech Research CorporationInventor: Cyrus K.
