Abstract: In a method of performing discovery, at least a plurality of identifiers associated with a plurality of respective communication devices is processed, using a first hash function, to generate a first bit string. The first bit string is indicative of whether each of the plurality of identifiers is included in a group. An indication that a new hash function should be used is detected, and, in response to detecting the indication that a new hash function should be used, at least the plurality of identifiers is processed, using a second hash function different than the first hash function, to generate a second bit string. The second bit string is indicative of whether each of the plurality of identifiers is included in the group.

Abstract: A valve assembly for use in an inner tube member of a core barrel head assembly positionable within a drill string of a drilling apparatus. The piston member of the valve assembly is located between a fluid pressure communication port and a fluid flow port to hold the retracting case in an up position and the latches retracted. After an increased fluid pressure has pushed the piston member past the annular element or bushing, the piston member substantially restricts fluid flow through the bushing and allows the retracting case to move to a down position and extend the latches. If the latches are not extended due to an obstruction or misalignment, the retracting case will prevent the piston member from completely passing through the bushing, thus maintaining high fluid pressure due to the flow ports remaining closed, and indicating to the driller that the latches have not properly latched.

Abstract: A device, system and method are provided for controlling the rate of infusion of fluids during infusion therapy using non-electric infusion devices. Rotation of a flow regulator dial causes an orifice connected to the inlet to modify its position relative to a particular one or more orifices or groove portions, the characteristics of which provide a certain flow rate characteristic. The flow regulator allows for the infusion pump to infuse at a rate that may be varied during use by the user. Additionally, the flow regulator is made from a material selected to operate under a wide range of pressures, from 5-40 PSI, making the flow regulator compatible with pressurized devices, such as, a non-electric pump.
