Abstract: A method for an audiovisual receiver to request an audiovisual transmitter to reset a communication link includes requesting the reset when the audiovisual receiver determines that the communication link is unlocked. The communication is determined to be unlocked when the active geometry of successive audiovisual frames transmitted from the transmitter to the receiver is determined by the receiver to be inconsistent. The communication is also determined to be unlocked when the interval between control bits of the successive audiovisual frames is inconsistent. When one or both of the inconsistencies is determined, the receiver sets an error bit in a register of the receiver that is accessible by the transmitter to determine from the receiver that the communication link is unlocked.

Abstract: An automatic online analyzer validation and calibration system receives operating parameter input signals from sensors, receives a measured value of a selected process variable from a physical analyzer, determines a difference between the measured value and an inferred value of the selected process variable determined by a controller based on the operating parameter input signals using an inferential analyzer; and if the difference between the measured value and the inferred value exceeds a threshold, initiates a recalibration of the physical analyzer or recalibration of the inferential analyzer. In one example, the automatic online analyzer validation and calibration is used in a gas dehydration system to validate and calibrate a physical moisture analyzer.

Abstract: To analytically determine concentration of dissolved gases in a water pipeline, a water sample is drawn from a source carrying water with dissolved gas, through a water source port of a four-way valve. The water sample is flowed from the water source port towards a syringe port of the valve and into a syringe fluidically coupled to the syringe port to hold the water sample. Inert gas is drawn through an inert gas port of the valve from an inert gas source and is flowed from the inert gas port towards the syringe port and into the syringe. A mixture of the water sample and the inert gas is flowed from the syringe port towards an analyzer port of the valve and into an analyzer fluidically coupled to the analyzer port.

Abstract: Systems and methods for intelligently pre-fetching data for input controls are disclosed. In particular, the disclosed systems and methods predict whether an input control is likely to be edited and only pre-fetches data for the input controls that have a high likelihood of being edited. This way, the presently disclosed systems and methods not only reduce latency in displaying recommended data results for input controls that are likely to be edited but also reduces the number of calls made to the backend server to retrieve the data as the data is not retrieved for all rendered input controls, but only the ones that are likely to be edited.

Abstract: A system and method for securing data storage devices in an information technology (IT) network storage system is provided. The security system comprises a security control computer and electronic locks, which are mounted in a data center cabinet to slots for holding respective data storage devices. The security protocol implemented by the control computer requires an authorized administrator to execute a lock/unlock command identifying a particular device, and to provide a first part of a combination key. Additionally, an on-site hardware engineer is required to input a second part of the key at a terminal on-site at the data center. Upon verification of the first key, and then the second key, the control computer unlocks or locks the appropriate electronic lock. The control computer also implements a data backup/flushing process prior to allowing removal of an online cache board to avoid data corruption, loss, or system interruption.
