A joining pin (3.2) with which two parts (1 and 2) made from a porous material, particularly wood or a wood-like material, are to be joined together, is anchored in the porous material at predetermined anchoring points (31, 33). For this purpose, a bore (4.2) with a closed inner end (41) is made in the parts (1 and 2). The shape of this bore (4.2) is so matched to the joining pin (3.2) that it can be introduced substantially without force expenditure into the bore and is positionable in a first position. At least one predetermined anchoring point (31, 33) between the joining pin (3.2) and the wall of the bore (4.2) is formed when pressure is built up by pressing the joining pin (3.2) with a pressing force (F) more deeply into the bore to a second position. Energy is supplied in a planned manner to the joining pin (3.2) so that at the predetermined anchoring points (31, 33) the thermoplastic material of the joining pin (3.2) is plasticized. The locally plasticized plastic material is pressed by the local pressure into the porous material of the parts and forms local, macroscopic anchors (10, 20). The joining pin (3.2) is, e.g., made entirely from a thermoplastic material and the energy for plasticizing is supplied thereto by ultrasonic vibration.

A multitouch-capable touchscreen is realized in that a large number of pressure sensors are attached under a flexible surface and thus both the pressure distribution and also the deformation of the surface is measured. Local pressure maxima occur due to the flexibility of the surface material with associated deformation on contact. As several local pressure maxima can exist, it is thus also possible to identify a plurality of contacts simultaneously. It is possible from the strength of pressure and pressure distribution to determine the force that is used for pressing such that this information can also be used in the user interface. Such sensors can be produced very efficiently and inexpensively by printing an ink that changes its resistance under pressure onto PCB tracks designed as sensor surfaces. The PCB tracks and the sensor surfaces can also be printed out using an ink with as low a resistance as possible.

An airborne network system (ANS) on a member aircraft receives incoming geo-referenced atmospheric data regarding atmospheric conditions from other member aircraft and can re-transmit the data to other members. An air data system senses local pressure and temperature conditions. A navigation system calculates geo-referenced aircraft position. An inertial data system senses member aircraft attitude, angular rates and accelerations. A data processing system (DPS) generates the member aircraft's perspective of the atmospheric conditions, based on input data from the above-mentioned systems. Network directed DPS output atmospheric data is provided to the ANS to be transmitted to other airborne network systems positioned on other member aircraft. An airborne display system is adapted to receive crew directed DPS output atmospheric data and in response thereto display desired atmospheric forecast conditions. An airborne caution / advisory system receives the crew directed DPS output atmospheric data and alerts the pilot(s) of hazardous flight conditions.

A structural and functional model for a lung or similar organ is virtually defined by encoding aspects of branching passageways. Larger passageways that are visible in medical images are surface mesh fitted to the anatomical surface geometry. Smaller distal passageways, beyond a given number of branch generations, are modeled by inference as linear passages with nominal diameters and branching characteristics, virtually filling the space within the outer envelope of the organ. The model encodes finite volumetric elements for elasticity and compliance in passageway walls, and for local pressure and flow conditions in passageway lumens during respiration. The modeling can assess organ performance, help to plan surgery or therapy, determine likely particle deposition, assess respiratory pharmaceutical dosing, and otherwise represent structural and functional organ parameters.

The mounting of a component subjected to pressure from a fluid requires special precautions if the component is made of wear resistant, hard and hence generally brittle material and may be destroyed by locally raised stresses. A fluidic component of this kind, made, for example, of silicon / glass is arranged in an elastomeric shaped component, made, for example, of silicon rubber. The inner contours of the elastomeric shaped component correspond to the outer contours of the fluidic component. The outer contours of the shaped component corresponds to the inner contours of a holder. Due to this "floating mounting" there are no unacceptable local pressure peaks and no deformation of the fluidic component. The device is particularly suitable for mounting a fluidic component made of glass or silicon, or miniature dimensions, subject to high pressure.

Systems and methods for mass flow controllers which minimize false flow conditions and display a reduced sensitivity to pressure transients are disclosed. Pressure gradients that exist within the volume of a mass flow controller fluid path are minimized in order to limit the potential energy contained in compressed or pressurized process gas. Additionally, process gas pressure may be monitored using a pressure sensor. This pressure signal is utilized in conjunction with a control algorithm to cancel the detrimental effect of certain flow components. These mass flow controllers may be used as drop in replacements for legacy mass flow controllers and reduce the cost of gas sticks due to elimination of discrete components such as pressure regulators, gas filters, pressure transducers, local pressure displays, isolation valves, seals, etc.

An improved micro slit viscometer includes a combined micrometer depth rectangular slit flow channel with monolithically integrated multiple pressure sensors in the flow channels and a pumping system that injects a test sample to the channel at a desired flow rate. Pressure sensing diaphragm of the monolithically integrated pressure sensors is smooth to minimize the flow disturbance thereby measuring accurate local pressures. With the measurement of the pressures at various locations of the channel the true viscosity of test sample can be calculated. The viscometer may consist of multiple flow channels and thus the true viscosity at multiple shear rates can be measured simultaneously for a given flow rate thereby obtaining a full viscosity curve as a function of shear rate of non-Newtonian liquids in a much faster manner. The viscometer needs only a miniscule amount of sample, which minimizes a waste of test material. The flow channels and the monolithically integrated pressure sensors are fabricated using microfabriaction processes on wafers and combined, which greatly reduce the production costs.

As a result, the liquid crystal device is provided with improved display qualities due to suppression of irregularities at the outside-pixel region and / or a local pressure distribution.

Rupture path logic methods of detecting, locating and isolating ruptures within a fluid piping system are disclosed, wherein a rupture within a piping system can be detected and isolated based solely upon local pressure and flow rate measurements at individual valves within the system without the need for communication of measured fluid data between valves at various locations throughout the system. A fluid characteristic is determined individually for each valve based upon the pressure and flow rate measurements at the valve, and that fluid characteristic is compared with set point fluid characteristic information to determine whether each valve is on a fluid path between a fluid supply source and a rupture. Upon detecting a rupture, valves detected as being on such a fluid path are automatically closed within the system in an order of valves furthest from all online fluid supply sources closing first, thereby ensuring eventual isolation of the rupture while allowing intact sections of the piping system to remain open and operational. An automatic rupture detection and isolation fluid piping system is also disclosed that utilizes rupture path logic methods to isolate detected ruptures within the system.

The invention relates to a working roll technology for controlling the edge drop of cold rolled steel. With the special high-order curve working roll forming technology, the technology solves the disadvantages that a rolling machine with a working roll which can not axially move has weak capacity of controlling the edge drop when electric steel is rolled. The technology can control the edge drop of the electric steel below 10 mu m, simultaneously improve the control performance of the plate shape of the rolling machine, increase the transverse rigidity for bearing roll gap, improve the state of contact pressure between rolls and prevent the roll from shelling off caused by local pressure peak. The technology is suitable for the cold rolling machine with the working roll which can not axially move, in particular for the rolling machine which infrequently changes the rolling width and the rolling specification.

A prosthetic sock configured to accommodate a transtibial amputee's residuum volume reductions which occur over time and are greater distally than proximally. It is also applicable to other amputee limbs and other levels of amputation of the leg and arm. The sock provides better compensation for the increased distal volume shrinkage and it reduces discomfort from localized loading on the stump by providing a knitted thickness that is greater distally and then tapers to a lesser proximal knitted thickness. A transtibial amputee's residuum is more sensitive to pressure over the tibial bone and this sock also provides a reduced local thickness over the tibial crest area which decreases the localized pressure in this region. Since the sock accommodates the loss of tissue volume in the distal end of the prosthetic socket, it thereby provides improved stump stability inside the prosthetic socket and improves amputee control and stability in walking.

With the invention, a negative pressure generation device is arranged in a steam flowing passage of the cooker body, and rapid suctioning is carried out so that the steam in the cooker body has no time to supplement the space where gas is suctioned by the device, to form, nearby the negative pressure generation device, a local low pressure space with a local pressure lower than the internal pressure inside the cooker body, so as to physically avoid rice water foam overflow during rice cooking and porridge cooking processes of the rice cooker.

One embodiment of a transition-to-turbine seal (320) comprises an upstream portion (322) adapted to engage a flange (416) of a transition (400). The upstream portion (322) may be U-shaped in cross-sectional profile and comprises a primary wall (324) that comprises a proximal section (325) and a distal section (326) relative to a hot gas path (170). The proximal section (325) comprises a plurality of recesses (327) which are spaced apart and separated by intervening wall (328). In each recess (327) is provided one or more outlets (329) of cooling fluid holes (339). The outlets (329) communicate via the cooling fluid holes (339) with a supply of compressed cooling fluid, such as compressed air that is provided from the compressor. During operation the outlets (329) release this fluid into the respective recesses (327). The flow of cooling fluid through such outlets (329) in the respective recesses (327) provides for a more uniform cooling effect that includes impingement and convective cooling. Further, the outlets and recesses reduce the likelihood of hot gas ingestion due to local pressure gradients. Toward its downstream end, the seal (320) also comprises a downstream groove (321) which is adapted to engage a lip (138, 139) of a row 1 vane segment (130). Variations of the transition-to-turbine seal are described.

The erosion process may be driven by a force-producing element that may also include a tissue-grasping element (144).

A two-mode therapeutic mattress system is provided, including a non-powered air mattress, a pressure dispersion cushion, and a selectively operable air diffusion coverlet in a common modular assembly for improved medical management of skin care. The non-powered air mattress includes longitudinal air cylinders providing a static air support system inflated to predetermined pressure. The longitudinal air cylinders are in pressure communication with elasticized reservoirs, in that the air level in the elasticized reservoirs dynamically reacts to changes in pressure in the longitudinal air cylinders, for example upon receipt of a patient upon the mattress system. The pressure dispersion cushion facilitates pressure relief with a number of lateral and longitudinal cuts resulting in a plurality of separate upright support cells, the size and construction of which may vary over the surface of the pressure dispersion cushion so as to provide selective support characteristics. The air diffusion coverlet contains a plurality of air pockets. The air diffusion coverlet operates in two modes: a “therapy mode” such that compressed air from an air compressor is pumped to the air diffusion coverlet, and an “off” mode in which the air pockets collapse to provide a suitable and relatively smooth bedding component to the therapeutic mattress system. The non-powered air mattress, pressure dispersion cushion, and selectively operable air diffusion coverlet cooperate to provide a single product that addresses localized pressure, maceration, shear stress, and dynamic changes in a patient's condition during the course of time.

A multi-touch capable touch screen or touchpad is implemented in that a large number of pressure sensors are attached below a flexible surface and both the pressure distribution and also the deformation of the surface are measured. Local pressure maxima arise due to the flexibility of the surface material with the attendant deformation upon contact. Because multiple local pressure maxima may exist, multiple contacts may thus also be recognized simultaneously. The force with which pressure is applied may additionally be ascertained from the pressure strength and the pressure distribution, so that this information may likewise be used in the user interface. Such sensors may be produced very efficiently and cost-effectively in that an ink, which changes the resistance thereof under pressure, is imprinted on printed conductors implemented as the sensor surfaces. Likewise, the printed conductors and the sensor surfaces may also be printed using an ink having the lowest possible resistance.
