A bulk acoustic wave resonator structure that isolates the core resonator from both environmental effects and aging effects. The structure has a piezoelectric layer at least partially disposed between two electrodes. The structure is protected against contamination, package leaks, and changes to the piezoelectric material due to external effects while still providing inertial resistance. The structure has one or more protective elements that limit aging effects to at or below a specified threshold. The resonator behavior is stabilized across the entire bandwidth of the resonance, not just at the series resonance. Examples of protective elements include a collar of material around the core resonator so that perimeter and edge-related environmental and aging phenomena are kept away from the core resonator, a Bragg reflector formed above or below the piezoelectric layer and a cap formed over the piezoelectric layer.

An automatic manipulator, such as a multiaxial industrial robot, with a carrying component structure (support structure) for transmitting forces between individual members of the automatic manipulator. The entire support structure is formed from a material that is inert with respect to external effects, such as moisture or the like. The material of the support structure may be, in particular, a material that is suitable for use in contact with foods, such as stainless steel, so that the automatic manipulator according to the present invention can be used reliably and without additional costly protective measures in environments in which there is a risk for contamination, such as in the food industry.

A method of using one or more microjets to create and/or control oblique shock waves. The introduction of microjet flow into a supersonic stream creates an oblique shock wave. This wave can be strengthened—by increasing microjet flow rate or the use of many microjets in an array—in order to form an oblique shock. Such an oblique shock can be used to decelerate flow in a jet aircraft engine inlet in a controlled fashion, thus increasing pressure recovery and engine efficiency while reducing flow instability. Adjusting the pressure ratio across the microjet actually alters the angle of the oblique shock. Thus, the use of microjets allows decelerating shock waves in an inlet engine to be properly positioned and controlled. Microjet arrays can also be used to ameliorate shock waves created by external aircraft surfaces, such as sensor pods and weapons. Microjets placed forward of any external protuberance can convert a single substantial shock wave into a series of much milder waves which will not produce unwanted external effects, such as strong sonic booms.

A passive magnetic latch is disclosed. The latch includes, according to various embodiments, a magnetically-actuated switch and a hard, non-linear biasing magnet. The switch may include components that, when polarized, cause the switch to transition from a first state to a second state. The biasing magnet is positioned proximate to the switch such that when the magnetization of the biasing magnet is changed by an external effect to thereby induce a modified magnetic field from the biasing magnet, the modified magnetic field polarizes the components of the switch such that the switch transitions from the first state to the second state and remains in the second state after the external effect is removed. A second external effect may be used to again change the magnetization of the biasing magnet such that the components of the switch depolarize and the switch transitions back the first state. As such, the magnetic latch may act like a remote ON/OFF switch.

A process for manufacturing a hybrid component. To manufacture a hybrid component with electronic components in a possibly continuous manufacturing process, it is proposed according to the present invention that the electronic component be extrusion-coated with a hot melt adhesive melting at low temperature and to extrusion coat the intermediate product formed with a conventional plastic suitable for injection molding in an additional injection molding operation. On the one hand, damage to the electronic component is reliably prevented from occurring by this procedure, and, on the other hand, a hybrid component can be manufactured with a housing that is insensitive to external effects.

The invention discloses a method for preparing a polystyrene/sodium monofluorophosphate microcapsule corrosion inhibitor, which comprises the following steps of preparing the sodium monofluorophosphate into water solution of sodium monofluorophosphate, adding emulgator and stirring for dissolution so as to prepare water phase, dissolving the polystyrene into PS (poly styrene) solvent to prepare oil phase, mixing the water phase and the oil phase for preparing W/O type emulsion, preparing protective colloid into water solution, adding the water phase into the prepared W/O type emulsion and stirring for mixing to obtain W/O/W complex phase emulsion, taking the mixed liquid out for standing and taking out a sediment layer after full volatilization of PS solvent, washing the precipitated particles with water, after sedimentation and filtration, drying in a vacuum drying box, thus obtaining the polystyrene/sodium monofluorophosphate microcapsule corrosion inhibitor particles.

By the method, the vortex-induced vibration of the deep-sea riser under the internal and external flow effect can be evaluated.

Disclosed is apparatus and a method for detecting udder disease in dairy animals. An accelerometer is attached to each of a plurality of dairy animals. A processor determines a measure of the activity of the dairy animals to which the accelerometers are attached. Data is recorded by and automatically transmitted from a sensor unit secured to an animal, without the requirement for costly and time consuming chemical analysis of milk, or of visual or veterinary inspection of individual animals in a herd. The development of an udder disease in a dairy animal, such as mastitis, may be identified from a decrease in the monitored measure of activity of a dairy animal. A separate baseline measure of activity may be determined for each dairy animal and the ac tivity of a plurality of dairy animals in one or more herds may be taken into account, in order to reduce false positives due to external effects which are not specific to a single dairy animal.

When a heating process is performed in a state where a thermal transfer sheet is superimposed on a scintillator plate, a film of the thermal transfer sheet is separated from the thermal transfer sheet and adhered onto the scintillator plate. The film includes a protective layer, an aluminum layer, and an adhesive layer. The aluminum layer is protected by the protective layer. Because the scintillator plate by itself functions as a rear surface support substrate with respect to the protective layer and the aluminum layer, a film which is highly resistive against an external effect can be formed. A plurality of films can be layered on the scintillator plate. A pressure transfer method can also be used for formation of the film. A scintillator member in which the film has been formed is disposed in a radiation measuring device.

Disclosed herein is an embedded chip antenna. The embedded chip antenna having a complementary radiator structure includes two radiators that have identical radiation characteristics and are respectively arranged on both sides of a feed point. According to the present invention, the radiator of a chip antenna has a single physical radiator structure, but is electrically formed of a plurality of partial radiators symmetrical with respect to a feed point, and radiation operations in high and low frequency bands are separately performed. Therefore, complementary operational characteristics that counteract external effects are implemented, so that, when part of a human body, such as the hand, affects one partial radiator on one side of the chip antenna, the other partial radiator on the other side thereof independently operates, thereby minimizing performance degradation originating from the outside of the antenna.
