Abstract: Systems, methods, and techniques for providing blockchain ledger-based authentication for reviews. In one example, a system obtains an identifier associated with an event, generates a contract based on the event, and broadcasts the contract to a blockchain ledger. The contract is fulfilled in response to cryptographically authenticated user input. In another example, a user writes a review, determines conditions for access to the review, and provides the review to a system, in which the system generates a contract based on the review and the conditions, and broadcasts the contract to a blockchain ledger. Viewers can access the review by fulfilling the conditions for access to the review of the contract.

Abstract: An integrated cryogenic fluid delivery system includes a tank adapted to hold a supply of cryogenic liquid and having an end wall. A shroud is positioned on the end wall and contains a shell and tube heat exchanger. The heat exchanger includes a shell defining a warming fluid chamber and having a shell inlet and a shell outlet in fluid communication with the warming fluid chamber. A number of cryogenic fluid coils are positioned within the warming fluid chamber and are in fluid communication with a cryogenic fluid inlet port and a cryogenic fluid outlet port. A fuel shutoff valve has an inlet in fluid communication with a liquid side of the tank and an outlet in fluid communication with the cryogenic fluid inlet port of the heat exchanger. A manual vent valve has an inlet in fluid communication with a headspace of the tank and an outlet. The fuel shutoff valve and the manual vent valve each have a control knob that is accessible from the first or second side of the shroud.

Abstract: An integrated cryogenic fluid delivery system includes a cryogenic liquid tank having an interior, a wall and a geometry. The interior of the cryogenic liquid tank contains a supply of cryogenic liquid. A fuel pickup line is positioned within the interior of the tank and is in fluid communication with a vaporizer so that the vaporizer receives and vaporizes cryogenic liquid from the tank. The vaporizer is positioned outside of the tank and is secured to the wall. The vaporizer also has a shape that conforms with the geometry of the tank.

Abstract: The implantable scaffold matrix composition for osteogenic regeneration has a biodegradable polymer material selected from the group consisting of one or more of polylactic acid, polyglycolic acid, or polycaprolactone, or any combination thereof to provide a time release delivery of an osteogenic effect and further has a pharmaceutical composition selected from the group consisting of one or more of ibuprofen, non-steroidal anti-inflammatory drugs (NSAIDS), acetaminophen, or naproxen sodium or any combination thereof and wherein the implantable composition has a primary and a secondary time release. The primary time release being one of the polymer compositions; each time release extending occurring between 0 days and 19 days, both not being at 0 days.

Abstract: A method and system for delivering media content to a user at predetermined times. A processing unit of the system receives streamed media content data and causes a display device to display the media content. The method and system include receiving user instructions and streaming media content according to the user instructions.

Abstract: User data stored on a first computer in a network is backed up to a computer which is one of a plurality of other computers in the network. The user data may be backed-up because a new operating system is to be installed. A request message indicating that the user data needs to be backed up is transmitted from the first computer to the network and is received at the other computers. One of the other computers is selected based on data indicating the extent to which each of the replying computers complies with one or more selection criteria. The first computer then transmits the user date to the selected computer with an identifier identifying the user data. The user data is stored in storage associated with the selected computer. The first and other computers may be in the same sub-network. The selection may be made by the first computer.

Abstract: This invention relates to a movement transfer mechanism for a portable power tool, such as a cutting device. The mechanism includes a movement transfer block, a shaft configured to be linked to a driving means, wherein the shaft includes a head configured to engage with the movement transfer block, a linking arm to a working element, which may be a cutting blade, the linking arm configured to engage with the movement transfer block, the mechanism characterised in that the movement transfer block includes a first aperture substantially in line with the head of the drive shaft, and a second aperture substantially inline with the linking arm of the working element. Rotation of the drive shaft causes reciprocal movement of the linking arm, and therefore movement of the working element with which the linking arm engages.

Abstract: A target machine in a sub-network requires network booting. The target machine broadcasts messages in the sub-network indicating that the target machine needs booting, and which are detected by other machines in the sub-network which are capable of booting the target machine. The other machines respond to the messages by electing one of them as a master boot control for the target machine. The elected machine controls booting of the target machine.
