  • Patent number: 10592621
    Abstract: A method for determining a stiffness of a tube bundle heat exchanger. The heat exchanger has a core tube and a plurality of coil tubes coiled around the core tube to form a tube bundle having a plurality of coil layers at a respective layer coiling angle. The method determines a geometric strength parameter for a coil layer, the strength parameter being an area ratio of a coil-tube cross-sectional area to a cell cross-sectional area resulting from the axial spacing of the coil tubes and an outer diameter of the coil tubes. The area ratio is corrected by a correction factor taking the orientation of the coil tubes of the coil layer in relation to the force of gravity acting on the coil tubes into consideration. The stiffness of the respective coil layer is determined from the corrected area ratio and a modulus of elasticity of the coil-tube material.

  • Patent number: 10571603
    Abstract: The object of the invention is a method implemented in a computer for the numerical simulation of a porous medium that may comprise multiple interacting hydraulic fractures in continuous or naturally fractured medium. The method calculates numerically the propagation of a crack, or set of cracks, for instance under the fluid pressure imposed artificially through a well or perforation in a rock mass. This is accomplished by using the Finite Element Method and the special elements named zero-thickness interface or joint elements in the specialized literature, which are pre-inserted along all potential crack paths in the rock mass (pre-existing natural and artificial fractures plus main potential new fracture paths).

  • Patent number: 10551258
    Abstract: Provided is a residual stress estimation method and a residual stress estimation device capable of suppressing the number of cut pieces to be collected for measuring inherent strain without deteriorating residual stress estimation accuracy. In a case where it is assumed that the inherent strain is uniformly distributed in one direction in a structure, a user measures residual stress from a cut piece collected in a region in which the inherent strain is uniformly distributed and inputs the measured value to the residual stress estimation device. The residual stress estimation device estimates a two-dimensional inherent strain distribution on an analysis surface perpendicular to the one direction in the structure using the input residual stress measured value, transfers the estimated two-dimensional inherent strain distribution to the one direction, and estimates a three-dimensional inherent strain distribution in the structure.

An indication is received when the portion of the medicament delivery device or the simulated medicament delivery device is removed from the adapter. A second wireless signal characterized by a second communication mode with the computing device is produced in response to the indication. The second communication mode is different from the first communication mode. The second communication mode can be, for example, a hold mode, a sniff mode or a park mode.

  • Patent number: 9879892
    Abstract: The invention relates to a method for configuring, on a control unit, operating parameters of a plurality of devices of a refrigeration system. A user selects on the control unit, among the plurality of devices of the refrigeration system, a first device to configure. Information of valid configurable operating parameters of the first device is provided on the control unit. The user selects at least one of the valid configurable operating parameters of the first device, thereby configuring the first device. Information stored about operating parameters of other devices of the refrigeration system, based on the configuration of the first device, is then provided on the control unit. Finally, the user confirms, on the control unit, one or more operating parameters of one or more of the other devices, thereby configuring the one or more other devices. The invention also relates to a control unit and a refrigeration system.

  • Patent number: 9857242
    Abstract: A method for analyzing a three-dimensional stress concentrating feature of a component (60), such as a borehole (62), using a two-dimensional probabilistic technique. A circumferentially-dependent stress concentration profile around the stress concentrating feature is determined, and then a probability of failure of the component is calculated using a 2D probabilistic failure analysis of the stress concentration profile. The probabilistic failure analysis may include a Monte Carlo theta integration approach.

  • Patent number: 9827672
    Abstract: A piezoelectric drive device includes a piezoelectric drive portion which includes a contact portion capable of coming into contact with a driven body and a piezoelectric material, and a drive circuit which drives the piezoelectric drive portion. The drive circuit sets an allowable maximum output torque Tlim or less to an allowable output torque range, sets output torque Td of the piezoelectric drive portion so as to be within the allowable output torque range, and operates the piezoelectric drive portion. The allowable maximum output torque Tlim is expressed by the following Expression (1). Tlim=r1×?k×Ns×fs??(1) In the expression, r1 is a distance between a rotation center of the driven body and a contact position of the contact portion, ?k is a dynamic friction coefficient between the driven body and the contact portion, Ns is a pressing force by which the contact portion presses the driven body when an operation of the piezoelectric drive portion stops, and fs is a coefficient of 1 or less.

  • Patent number: 9791311
    Abstract: Methods are provided for: (i) measuring the position of the blade stagger angle axis for one or more blades of a row of blades attached to a rotor, (ii) measuring the blade tip stagger angle for one or more such blades, and (iii) measuring the blade tip axial displacement for one or more such blades. The methods use forward and rearward blade tip timing datasets for successive rotations of the blades from two axially spaced blade tip timing probes. The forward probe is forward of the rearward probe along the axial direction of the rotor. The blade tip timing datasets allow the times of arrival of the blades at the respective probes to be measured. The methods also use a once per revolution dataset for the successive rotations of the blades. The once per revolution dataset allows the angular velocity of the blades to be measured.

  • Patent number: 9734608
    Abstract: Adding a new disjoint graph diagram to an existing graph diagram. A set of one or more new nodes from a graph to be added to a first graph diagram are identified. An automatic graph diagram layout of the set of one or more new nodes is performed creating a second graph diagram. The first graph diagram is aligned along a first axis with the second graph diagram Nodes in the first graph diagram that are at least partially between a first point and a second point of boundaries of the second graph diagram are identified. A boundary is created around the nodes in the first graph diagram that are between the first and second points. The second graph diagram is moved along a second axis toward the boundary to create a combined graph diagram.

  • Patent number: 9642725
    Abstract: The present invention relates to joint simulators, and in particular, to methods and systems for controlling joint simulators by using a haptic mapping technique. A joint simulator is used to closely approximate the conditions within the body, particularly with respect to human and animal joints, and can be used to test and evaluate prosthetics for use in various parts of a human or animal body. The haptic mapping technique improves the rate of convergence of the actual testing forces to the prescribed forces during repetitive performance and life testing. The method is used in conjunction with an impedance-mode servo controller.

  • Patent number: 9636871
    Abstract: 3D printing may be optimized by segmenting input jobs and/or combining parts of input jobs together. In an embodiment, a user-defined metric is received associated with each input job and this is used in scheduling input jobs to optimize latency and/or throughput of the 3D printing process, along with the printing envelope and other characteristics of the 3D printers used. In various embodiments, the scheduling may comprise dividing a 3D object into a number of parts and then scheduling these parts separately and/or combining 3D objects, or parts of 3D objects, from various input jobs to be printed at the same time on the same 3D printer. In various embodiments, the scheduling is repeated when a new input job is received and changes made during printing. In various embodiments, a user may submit an updated version of an input job which is already in the process of being printed.
