Patent number: 11734080Abstract: Embodiments relate to reading signals from a stimulus file produced by an emulator into a data store. A method includes executing, by a set of one or more worker processes, reading tasks. Each reading task is executable independent of other reading tasks. Each reading task includes reading a time slice of a signal from a stimulus file produced by a hardware emulator, and pushing a partial waveform corresponding to the time slice to a data store. The partial waveform includes a head and a tail that each has a smaller data size than an entirety of the partial waveform. The method further includes executing stitching tasks. The stitching tasks include pulling the heads and tails of the partial waveform from the data store, modifying the heads and tails to indicate a temporal order of the partial waveforms, and pushing the modified heads and tails back to the data store.Type: GrantFiled: April 7, 2021Date of Patent: August 22, 2023Assignee: Synopsys, Inc.Inventors: Anup Kumar Sultania, Ajay Singh Bisht, Mark W.

Publication number: 20180043584Abstract: The present invention relates to a process to reduce internal stresses in insulation molded onto complex pipes, preferably complex subsea pipe, to reduce cracking in the molded insulation. Insulation materials applies to complex pipes comprising branches, i.e., valves, and the like, may be susceptible to cracking at, or near where the branch connects to the pipe as the coating of insulation material cures or hardens. The process of the present invention aims to reduce post molded cracking by reducing molded in stress at the branch/pipe junction. This is accomplished by providing a preform at or near a branch/pipe junction prior to applying the coating of insulation material.Type: ApplicationFiled: March 18, 2016Publication date: February 15, 2018Inventors: Jie Feng, Mark W.

Patent number: 8973565Abstract: An apparatus and method for inflicting brain injury on a laboratory animal that employs a platform for supporting the laboratory animal. The platform defines an opening for positioning the head of the laboratory animal over the opening. A projectile is launched from a projectile launching device orientated below the opening of the platform. The projectile launching device has a means for propelling the projectile directly at and/or through the opening of said platform, thereby inflicting brain injury on the animal via either a pressure wave or concussive impact of the projectile. Without helmet, direct impact of the projectile results in severe traumatic brain injury. Use of helmet protects animals from skull fracture, subdural hematoma, intracerebral hemorrhage and contusion yet produces mild concussion-like pathology.Type: GrantFiled: August 8, 2012Date of Patent: March 10, 2015Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Zhiyong Chen, Zhilin Liao, Frank C.

Patent number: 7702473Abstract: A submersible biomonitoring system for monitoring water quality in situ includes a submersible chamber constructed of a di-electric material and sized to allow suitable signals from one or more aquatic organisms to be received by eliminating cross-talk between cells while allowing ambient conditions to be maintained inside the chamber. The aquatic organism exhibits ventilatory behavior and body movement sensitive to water quality which manifest as electrical signals picked up by electrodes and communicated to a pre-amplifier that conditions the signals for communication to a land-based amplifier and/or controller that is used to interpret the signals to determine when the water to which the organism is exposed has caused physiological stress to the organism.Type: GrantFiled: April 17, 2007Date of Patent: April 20, 2010Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Mark W.

Patent number: 6988394Abstract: A portable automated biomonitoring system for monitoring water quality includes an exposure chamber for housing an aquatic organism and a water inlet for directing water to the exposure chamber. The aquatic organism has ventilatory behavior and body movement sensitive to water quality. Electrodes sense electrical signals produced by the organism during its ventilatory behavior and body movement, and a controller responsive to signals from the electrodes determines a plurality of ventilatory parameters based on the signals. The ventilatory parameters are compared with corresponding thresholds to determine when the water to which the organism is exposed has caused physiological stress to the organism. The water being evaluated may be recirculated through the system for further analysis.Type: GrantFiled: February 3, 2004Date of Patent: January 24, 2006Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Tommy R.
