Abstract: A check valve bleed assembly eliminates the requirement for a person to enter the red zone when bleeding the grease out of a gate or other valve. A gas or other fluid is provided to the check valve bleed assembly. The gas or other fluid acts upon the surface driving a pin into the associated check valve with sufficient force to overcome the resistance of the object sitting on a seat and moves the object off of the seat. The force is maintained as long as is necessary. Usually, the check valve is held open until the gate transitions into the gate's associated gate recess thereby displacing the grease within the gate recess through the check valve, into the check valve bleed assembly, and finally to a waste collection tube. In some embodiments a gate valve greasing access port is included in the check valve bleed assembly such that grease may be injected into the check valve bleed assembly.

Abstract: A multi-tenant system provides software-updating functionality that selectively updates tenant systems according to a number of different factors. In some embodiments, the factors include evaluation of “health metrics” that quantify how well tenant systems are functioning after an update of software components to the latest version, policies specified by either the tenants or the multi-tenant system (or both), and/or “kill switches” specified by the multi-tenant system that prevent updating, as some examples.

Abstract: A security system used by an organization maintains a PKI used for issuing digital certificates (hereinafter for brevity also referred to simply as “certificates”) and provides the PKI to the organization as a network service. In order to simplify the use of the PKI for purposes such as obtaining certificates, the security system additionally provides a mechanism for using a designated flow protocol to interface with whichever MDMs the organization uses. This mechanism permits administrators or other users to provision certificates to their organization's client devices with just a few actions within a user interface.

Abstract: A system and method of automatically detecting pricing loops by generating a price-history database and searching the database for recurring pricing update patterns. If a price update pattern is detected, then the price republishing is blocked until a next event occurs to interrupt the pricing loop. A pricing engine searches the price-history database before publishing a new price. If a past price recurs multiple times over a predetermined time period, then it is saved as a candidate value for a pricing loop. A current price to be published is compared to the candidate value, and if there is a match, then the current price is suppressed.

Abstract: An organization uses an independent separate authentication system to authenticate users or the organization for access to resources of the organization. The organization also uses an MDM system independent both of the organization and of the authentication system to administer the client devices of the organization's users and to ensure that the client devices handle the resources of the organization in a secure manner. In order to allow the authentication system to consider MDM management status of a client device when authenticating a user, the authentication system and the organization cooperate to establish a mechanism whereby the authentication system can securely determine whether a particular client device requesting access to an organization resource is in fact managed by an MDM system.

Abstract: A greasing system may be placed partially within the red zone and partially outside of the red zone. Grease and pneumatic power is supplied from outside of the red zone to a pod, inside of the red zone, having local storage, high-pressure pumping capacity, and a distribution mechanism. The grease is supplied from outside of the red zone to the pod at low-pressure through a hose having at least a 1 inch inside diameter and is usually at least 100 feet long. The pod pressurizes the grease to a high-pressure and distributes the grease via a distribution mechanism to a relatively short hose, generally less than 8 feet between the distribution mechanism and the greasing point on the wellhead, in order to minimize pressure losses.

Abstract: A hydraulic accumulator system is provided to remove the motors or engines from the red zone while maintaining sufficient capacity within the red zone to quickly close the designated blowout preventer or other gate valves. Additionally, a single point is provided outside of the red zone to charge the local storage units or to open or close the designated blowout preventer or other gate valves when time is not a critical consideration.

Abstract: A wellhead is provided having a port or ports about the external periphery of the wellhead. The center bore of each port is generally directed at a point within the wellhead having a location where a portion of a tool or an object is expected. Each port does not provide fluid access from the exterior to the interior of the wellhead and preferably has a flat bottom. Each port is fitted with a sensor and preferably the sensor contacts the bottom of the port. And ultrasonic a sensor emits an ultrasonic waveform which proceeds through the bottom of the port and a portion of the ultrasonic waveform is reflected back to the ultrasonic receiver. A comparison is then performed to compare the predicted value versus the received value to determine whether or not the expected tool or object is in place or partially in place within the wellhead.

Abstract: A sensor system to prevent the unintended severing or damage to a cable or other object within the throughbore of a standpipe or wellhead that may include a blowout preventer and gate valves. Generally, a sensor which may include both an emitter and receiver, is affixed externally to the standpipe, wellhead, blowout preventer, or gate valves. None of the emitter or receiver penetrates the pressure vessel formed by the standpipe, wellhead, blowout preventer, or gate valves. The sensor system may detect disturbances in a pre-existing field such as a geomagnetic sensor detecting the earth's magnetic field, the sensor may create a field and then detect disturbances within that created field such as a magnetic sensor, or the sensor may send a pulse of energy towards the area to be sensed and then read the reflected energy. Generally, the sensor system includes a logic controller, a memory, a sensor or sensors that may or may not include emitters and receivers, and a display.

Abstract: A sensor system to indicate whether or not the gate valve is open, closed, or at some position between.
