A medical device assembly is disclosed, comprising: a medical device; a fluid and a package forming a storage compartment, which at least partly accommodates the medical device, and a fluid compartment, housing the fluid, wherein a first joint separates the storage compartment and the fluid compartment, the first joint forming a first rupture zone.

The present invention provides a regeneration process of the etching solution for the silicon nitride film, applying phosphoric acid aqueous solution, wherein multiple numbers of filters are connected to the piping path of etching solution extracted from the etching tank by switching alternately in parallel or in series; in both cases that said multiple numbers of filters are connected in parallel or in series, said extracted etching solution being supplied to a filter with a filter element of a high silicon removal rate of silicon compounds with already deposited silicon compounds, thus maintaining a high silicon removal rate of silicon compounds.

A method for manufacturing a custom orthosis, such as an ankle brace, includes use of scanning processes. A digital model of a surface may be applied to a digital orthosis model to define a custom digital orthosis model. The digital model and, thus, the custom digital orthosis model may include one or more standard features. The custom digital orthosis model may be used with an automated manufacturing process to make some or all of the custom orthosis. In some embodiments, additive manufacturing processes may be used to form a portion or all of the custom orthosis.

A dowel including an anchor rod (2; 22) having a load application element at one of its longitudinal ends and a head (3; 23), a diameter of which increases toward the free end of the anchor rod, at its opposite end, an expansion sleeve (4; 24) having a bore through which the anchor rod (2; 22) extends and a plurality of expansion tabs (5; 25) separated from each other by longitudinal slots (6; 26) and extending from a circumferential groove (7) toward the head (3; 23), the expansion tabs (5; 25) expanding radially, upon the expansion sleeve (4; 24) being displaced over the head (3; 23), and a substantially ring-shaped member (8; 28) arranged in the circumferential groove (7) and substantially filling out the circumferential groove (7; 27) in an expanded condition of the expansion tabs (5; 25).

There is provided a method of forming a nitride semiconductor layer, including the steps of firstly providing a substrate on which a patterned epitaxy layer with a pier structure is formed. A protective layer is then formed on the patterned epitaxy layer, exposing a top surface of the pier structure. Next, a nitride semiconductor layer is formed over the patterned epitaxy layer connected to the nitride semiconductor layer through the pier structure, wherein the nitride semiconductor layer, the pier structure, and the patterned epitaxy layer together form a space exposing a bottom surface of the nitride semiconductor layer. Thereafter, a weakening process is performed to remove a portion of the bottom surface of the nitride semiconductor layer and to weaken a connection point between the top surface of the pier structure and the nitride semiconductor layer. Finally, the substrate is separated from the nitride semiconductor layer through the connection point.

A downhole release tool for use in conjunction with multiple select-fire perforating guns and a method for electronically actuating the release tool using either positive or negative control voltage. In a preferred embodiment, the release tool employs operating circuitry that allows actuation of the release tool by either a positive or a negative voltage at an absolute magnitude greater than the absolute magnitude of positive or negative voltages used to arm or fire the perforating guns.

A monitoring unit which is locally assigned to a bus controller of a user of a communication system, for monitoring and controlling the access to a data bus. Bus controller accesses data bus via a bus driver, and monitoring unit monitors and controls the access authorization of bus driver to data bus. In order to detect also permanent disturbances of bus controller and resulting errors of bus controller when accessing data bus monitoring unit has an arrangement for implementing a question-answer communication with bus controller and that it enables the bus controller to access data bus only if the question-answer communication establishes a proper functioning of bus controller.

The system comprises: a signal generating module, a light source module, an optical frequency comb generating module, a frequency sweeping and pulse generating module, an optical circulator, a sensing fibre, an interference module, a photoelectric conversion module and a detection and position module. The method comprises: obtaining a plurality of Rayleigh backscattering signals of the sensing fibre; performing a fading elimination processing on the Rayleigh backscattering signals, thereby obtaining a plurality of averaged Rayleigh backscattering signals of non-interference fading and polarization fading; performing a phase processing on the averaged Rayleigh backscattering signals, thereby obtaining phase variance curves; and determining a vibration point according to variances in the phase variance curves, and finally obtaining a position and a vibration waveform of the vibration point.

A battery that cycles lithium ions includes at least one first monopolar electrode having a first polarity and having a first tab and at least one second monopolar electrode having a second polarity opposite to the first polarity and a second tab. The first tab and the second tab are in direct electrical communication with an external circuit. At least one bipolar electrode is disposed between and electrically insulated from the first monopolar electrode and the second monopolar electrode, wherein a first side of the bipolar electrode has the first polarity and a second side of the bipolar electrode has the second polarity. The battery thus comprises at least one first unit cell connected in parallel and at least one second unit cell connected in series.

The present invention is a flexible picture frame. The frame stretches so that a user can insert a picture, a picture and picture cover, or a picture, picture cover, and backer section. Once the components are disposed in the flexible frame, it then recovers to its original shape and size. The flexible frame contains grooves on the inside walls to contain the picture and other components.
