Abstract: Embodiments of machines, systems, computer-implemented methods, and computer program products certify oil and gas well equipment. Embodiments identify a selected well equipment device, a device test specification, and testing sequences to be performed by a corresponding testing apparatus. Embodiments select a testing sequence responsive to the selected device. Embodiments control the testing apparatus for the selected testing sequence so that the corresponding testing apparatus performs the sequence responsive to the device test specification. Embodiments generate testing data for the selected testing sequence and link the testing data for the selected testing sequence to the device identifier for the device so that a certificate can be generated. Embodiments generate a certificate for the selected device responsive to the testing sequences having been performed upon the selected device and link the certificate for the selected device to the device identifier so that the certificate can be readily recalled.

Abstract: A valve assembly adapted for use in oil and gas operations. In one aspect, the valve assembly includes a valve body defining an internal region, an inlet passageway, and an outlet passageway, the inlet and outlet passageways extending into the internal region; a valve seat connected to the valve body and defining a fluid passageway; a clapper extending within the internal region and defining an annular groove; and a seal extending within the annular groove of the clapper and adapted to sealingly engage the valve seat. In an example embodiment, the clapper is actuable between an open configuration, in which fluid flow is permitted through the fluid passageway; and a closed configuration, in which the seal sealingly engages the valve seat to at least partially restrict fluid flow through the fluid passageway.

Abstract: Time after time studies find that often, even when administered by trained professionals, cardiopulmonary resuscitation (CPR) compression rates and depth are inadequate. Too week, shallow or too forceful compressions may contribute to suboptimal patient outcome. Several parameters are crucial for optimal and properly-administered CPR. Crucial parameters include proper hand positioning on the patient's chest, depth of compression of 4-5 cm, and compression rate of 100 compressions per minute. The crucial parameters are often affected by patient parameters, and relative to the patient, rescuer parameters, such as patient thoracic volume; weight; age; gender; and rescuer's, relative to the patient's, parameters, such as weight, height; physical form, etc. Proposed is an automated CPR feedback device with user programmable settings for assisting with real-time feedback and subsequently correcting rescuers patient customized CPR technique.

Abstract: The present invention relates generally to a support structure for fixating a patient to a treatment unit, and especially to a support structure for fixating the patient to a cardiopulmonary resuscitation unit. An embodiment of the support structure includes a back plate for positioning behind the patient's back posterior to the patient's heart and a front part for positioning around the patient's chest anterior to the patient's heart. Further, the front part can include two legs, each leg having a first end pivotably connected to at least one hinge and a second end removably attachable to the back plate. The front part can further be devised for including a compression/decompression unit arranged to automatically compress or decompress the patient's chest when the front part is attached to the back plate.

Abstract: A method and apparatus of coordinated voltage control for electric power systems with at least two substations and at least one load, a method of controlling distribution of reactive power between substations within a power system of similar parameters, and a method of reduction of interaction between voltage control modules in the said power system are disclosed. The purpose of coordinated control is to maintain acceptable voltage with minimal deviation from the set point across all elements of the power system. Disclosed coordinated control is accomplished via each substation's transformers equipped with on load tap changers (OLTC) and electrical generators Automatic Voltage Regulators (AVR) using proportional-integral-derivative control embedded in coordinated master controllers.

Abstract: A defibrillator system optimizes the timing and manner of applying a defibrillator charge to a patient based upon data provided to the defibrillator from a utility module or one or more external devices. A parameter module on the utility module provides the defibrillator with patient parameter information. Devices external to the utility module may provide the utility module with coaching data that the utility module may pass through to the defibrillator as a proxy to the external devices. The utility module may also provide external devices with patient data that the utility module may pass through to the external devices as a proxy to the defibrillator on a scheduled or other basis. The utility module may additionally provide a reserve of power to enable defibrillators to be used where power is unavailable and to enable defibrillators to deliver multiple charges more readily anywhere, anytime.

Abstract: A networking thermostat is described that includes a main processor and a communications processor. The main processor includes a network manager function, a master messaging function and a slave messaging function while the communications processor includes a wireless radio enabling the thermostat to communicate with other networking thermostats. The networking thermostat is able to operate in a master mode or a slave mode, where the master mode allows the networking thermostat to act as a main gateway between other networking thermostats and a remote server. When in the master mode the networking thermostat can default to a slave if communication with the remote server is lost, thereby allowing one of the other networking thermostats to become a master.

Abstract: Method and system for assigning addresses to end point devices in a network includes placing a mobile device in close proximity to a first end point device and establishing a wireless connection, transmitting an auto-addressing command from the mobile device to the end point device in response to the connection being established and disconnecting the connection in response to the end point device being configured with the network address. As the mobile device is moved through the system, when the wireless signal strength between the mobile device and a respective the end point device exceeds a threshold, both devices recognize that they are in close proximity and the mobile device transfers the address configuration information to the end point device. By moving the mobile device through the system the steps are automatically repeated until the mobile device assigns address and location information to each end point device on the network.
