A reference monitor system, apparatus, computer program product and method are provided. In one illustrative embodiment, elements of the data processing system are associated with security data structures in a reference monitor. An information flow request is received from a first element to authorize an information flow from the first element to a second element. A first security data structure associated with the first element and a second security data structure associated with the second element are retrieved. At least one set theory operation is then performed on the first security data structure and the second security data structure to determine if the information flow from the first element to the second element is to be authorized. The security data structures may be labelsets having one or more labels identifying security policies to be applied to information flows involving the associated element.

A cargo trailer having a frame assembly with pivotally mounted wall structures or frames. The frame assembly can be collapsed into a compact shipping configuration wherein the wall structures are positioned substantially parallel with the floor structure of the trailer. Various parts of the cargo trailer can also be stowed in the collapsed frame assembly for shipment of the frame assembly and stored parts. After shipment of the cargo trailer, the wall structures are pivoted into their upright positions and the final assembly of the cargo trailer is completed. Exterior panels may be shipped together in a compact stack with the frame to the final assembly location where the panels are attached to the cargo trailer.

An axle beam suspension system for a mobile vehicle, the system includes a main vehicle body, an axle attached to the main vehicle body, a control bar, and a track bar. The track bar includes a controlling connection portion. A first end of the track bar is attached at a lateral attachment to a lateral joint connection portion of the main vehicle body. A second end of the track bar is attached at a pivot attachment to a pivot joint portion on the axle. The control bar has a first end attached at a control attachment to a control joint connection portion of the main vehicle body and a second end attached at a fourth attachment to the controlling connection portion of the track bar. A lateral portion of an axle-pivoting-movement is transferred into lateral movement of the axle beam suspension system.

A flapper valve assembly is described having an equalizing port assembly with a bleed valve member that is moveable between an open position and a closed position. The equalizing port assembly features a structural support member in the form of a retainer key that is secured to the flapper valve member both axially and radially. Additionally, a compressible spring is located between the structural support member and provides biasing force upon the valve member to urge it toward a closed position. Additionally, the flapper valve member presents a pair of raised, substantially flat actuator contact portions upon its downstream face to meet an actuating tube in a mating contact arrangement and resist material deformation that could tend to clog or block the equalizing fluid flow port.

The invention provides techniques and devices for treating atherosclerotic disease using controlled cryogenic cooling, often in combination with angioplasty. The efficacy of endoluminal cryogenic cooling is enhanced by limiting cooling of target tissues using an insulated cryogenic balloon, the insulation ideally comprising a fluid which undergoes a phase change at a predetermined temperature. A combination cryogenic/angioplasty catheter avoids exchange procedures between dilation of a stenotic region within a vessel wall and the application of cryogenic cooling. The combination angioplasty/cryogenic cooling catheter may cool the diseased blood vessel before, during, and/or after dilation. Controlled cooling of the vessel wall may change its mechanical properties, weakening the vessel and allowing it to be expanded at a much lower pressure than with conventional uncooled angioplasty.

摘要:
An exercise machine is provided for developing the chest muscles while maintaining correct biomechanical posture and joint movement for the user, thereby maximizing efficiency and safety. The exercise machine includes a track on which two platforms independently slide. The platforms are each interconnected to a weight stack unit or other vertical resistance unit that provide resistance to the inward movement of the platforms. Each platform may also be connected to a tension element or resistance band that is configured to provide gradual and progressively increased resistance as the platforms are moved inwardly towards the center or center stop of the track.
摘要:
The present invention relates to exercise equipment and more particularly to a resistance band having a pair hand adapters, a pair of handles, and an extension interposed between each hand adapter and handle. The present invention farther relates to a hand adapter having a plurality of finger loops that are configured to contact the back surface of fingers of a user's hand, and the surface of the hand adapter to which the plurality of finger loops is attached is configured to contact the palm surface of the user's hand.
摘要:
An automatic vent valve and method for use is provided equalizing the pressure in at least two lines. A housing has a first piston that compresses a bias device when the second pressure source supplies sufficient pressure. Upon a sufficient reduction in pressure the first piston releases a second internally held coaxial piston to allow fluid to flow from a first pressure source towards a second pressure source, thereby equalizing the pressure between the two pressure sources.

Medical devices, systems, and methods for pain management and other applications may apply cooling with at least one probe inserted through an exposed skin surface of skin. The cooling may remodel one or more target tissues so as to effect a desired change in composition of the target tissue and/or a change in its behavior, often to interfere with transmission of pain signals along sensory nerves. Alternative embodiments may interfere with the function of motor nerves, the function of contractile muscles, and/or some other tissue included in the contractile function chain so as to inhibit muscle contraction and thereby alleviate associated pain. In some embodiments, other sources of pain such as components of the spine (optionally including herniated disks) may be treated.
