Abstract: A method to implement traceability and provability on a particular project in software development based on blockchain-recorded transactions of assigned developer time, the method comprising of the following steps: setting up a blockchain network comprised of a distributed, redundant, and tamper-resistant ledger; issuing each user an attestable pre-fabricated and signed virtualized environment on approved hardware that comes with functionality required for the user's role implemented as one of a set of virtual machine templates fashioned from a signed and approved pre-fabricated image; and verifying that assigned developer time is valid, and if so, record each development action on the ledger to enable extensive tracking and auditing of end-to-end software development process.

Abstract: A printable substrate, along with methods of its formation, is generally provided. The printable coating can include a base sheet defining a first surface and a second surface and a printable coating on the first surface of the base sheet. The base sheet can be constructed from a cellulosic nonwoven web and a saturant. The printable coating can include a plurality of inorganic microparticles and a crosslinked material, where the crosslinked material is formed from a crosslinkable polymeric binder and a crosslinking agent. An image can be formed on the printable substrate, such as by printing an ink composition onto the printable substrate (e.g., onto the printable coating).

Abstract: A mechanism for moving elements in a fluid filled housing using a pump with the element to be moved attached rigidly to the pump or to a port assembly connected to the pump. The pump assembly or port assembly moves as a result of differential pressure created between a first and a second chamber separated from each other by the pump assembly or port assembly. Movement of the fluid in one direction increases or decreases pressure, the pressure change resulting in a net force in one direction or the other.

Abstract: A formation tester for determining the formation pressure of a subsurface formation traversed by a wellbore comprises of:—an elongate tester body;—a support plate (3) that is extendible outwardly from the surface of the formation tester body, said support plate carrying probe means (5) to establish a passageway between the inside of said formation tester body and said formation, and a sealing pad (6) connected to said probe means to isolate said passage way between the inside of said formation tester body and said formation;—anchoring means (7) to settle said tester body at a level within the wellbore. The elongate tester body comprises an eccentric portion (2) wherein said support plate is mounted such that a determined standoff is maintained between said elongate tester body and the wall of the wellbore when said tester body is settled at a level in the wellbore.

Abstract: A method for determining formation fluid pressure in earth formation surrounding a borehole wall uses a downhole probe coupled to a variable-volume cavity. The probe is driven into contact with formation at the borehole wall. The method includes expanding the volume of the cavity during a first period of time to establish fluid communication between tool fluid and formation fluid, by withdrawing a minimal amount of fluid from the formation. During a second period of time the tool pressure is allowed to equilibrate to formation pressure. When pressure equilibrium is established, formation fluid pressure is set equal to tool pressure. A preferred embodiment includes terminating expanding the volume of the cavity on detecting a break in the mud cake seal.
