摘要： The Heartbeat Failure Detector of the present invention, is a new, simple method and device that has several identical modules, and each module is attached to a processor in the system. Roughly speaking, the module of a processor x maintains a heartbeat counter for every other process. For each process y, the counter of y at x (called the heartbeat of y at x) periodically increases while y is alive and in the same network partition, and the counter stops increasing after y crashes or becomes partitioned away. Using such a device, x can solve the communication problem above by resending m only if the heartbeat of y at x increases. Note that if y is crashed (or partitioned away from x), its heartbeat at x stops almost immediately, and so x will also immediately stop sending copies of m to y.

摘要： New failure detector mechanisms particularly suitable for use in asynchronous distributed computing systems in which processes may crash and recover, and two crash-recovery consensus mechanisms, one requiring stable storage and the other not requiring it. Both consensus mechanisms tolerate link failures and are particularly efficient in the common runs with no failures or failure detector mistakes. Consensus is achieved in such runs within 3□ time and with 4n messages, where □ is the maximum message delay and n is the number of processes in the system.

摘要： A method of forming a high temperature sensor includes preparing a substrate having a surface from an electrically insulative material having a first coefficient of thermal expansion (CTE), preparing an electrical conductor from a metal material having a second CTE that is different from the first CTE, and creating an interface between the electrical conductor and the substrate with a CTE blending medium that is provided between the substrate and the electrical conductor. The CTE blending medium accommodates differing thermal expansion rates of the substrate and the electrical conductor at temperatures of at least 700° C.

摘要： A reusable adhesive pad with embedded magnets consists of a layer of fibrous cloth with elasticity, a layer of silicone gel padding, and permanent magnets. The fibrous cloth with elasticity is made from fiber materials with a stretchable characteristic. The silicone gel padding is spread out fully and glued on one surface of the fibrous cloth with elasticity. In addition, the silicone gel padding is provided with holes that the permanent magnets with cylindrical or conical outers can be filled in and glued to the adhesive surface of the fibrous cloth with elasticity. Since the other sides of the permanent magnets protrude outwards the surface of the silicone gel padding, applying the invention to the human skin can perform the acupuncture and moxibustion treatment and the magneto-therapy to lessen painful discomfort.

摘要： A gantry assembly includes a main beam extending between a first and a second end. A plurality of legs including a pair of first legs and a pair of second legs attached to the main beam. A pair of first trolleys is slidably attached to the main beam. A first girder is attached to each one of the first trolleys and extends outwardly from the first trolleys for movement with the first trolleys. The first girder includes a pair of posts having a first and a second post disposed spaced from one another. The first post is attached to the first girder and extends downwardly from the first girder. The second post is slidably attached to the first girder and is movable along the first girder toward and away from the main beam allowing the gantry assembly to have different widths to accommodate for a single or double railway bridge.
