摘要:
An eyewear retention device with a cable having sufficient strength so that, when worn on eyeglasses over the ears, the cable is suspended in an arc above the wearer's neck, shoulders or garments.
摘要:
An adjustable eyewear retention device having two cables, two temple retainers, guiding means and grasping means which allow adjustment of the device to the dimensions of a user's head. In another embodiment, the guiding means is eliminated and the cables are connected by means of the grasping means.
摘要:
An eyewear retention device is disclosed that includes a length of resilient cord, such as cabling having a smooth plastic outer sheath, and terminating at each end in a tapered, rubberized retention tubing, and including retention end grommets molded against the ends of the cabling to prevent the slipping off of the retention tubing from the cabling. The combination of the resilient cord and the retention tubing produces a tensioned arc such that in addition to retaining eyeglasses to the vestment of a user when not in use, the retention device forms a suspended arc over the wear's upper torso such that the device does not contact the wear's upper torso or their vestment when donned over a wear's eyes.
摘要:
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.
摘要:
A system, apparatus, computer program product and method for authorizing information flows based on security information associated with information objects is provided. A hash key is generated based on an information object and a lookup operation is performed in a hash table based on the hash key. A determination is made whether an entry in the hash table at an index corresponding to the hash key identifies a labelset for the information object. A labelset, identifying a sensitivity of the information object, is stored in the entry at the index corresponding to the hash key for the information object if a labelset for the information object is not identified in the entry in the hash table. Information flows involving the information object are authorized based on a lookup of the labelset associated with the information object in the hash table. The hash table may be a multidimensional hash table.
摘要:
A variable capacity automotive refrigerant compressor is provided with a pressure equalization passage between the crankcase volume and the suction passage in the manifold to prevent a pressure imbalance between the two that could otherwise cause a reduction in crankcase lubricant retention during extended periods of system inactivity.
摘要:
Improved devices, systems, and methods for inhibiting hyperplasia in blood vessels provide controlled and safe cryotherapy treatment of a target portion within a body lumen of a patient. Efficacy of endoluminal cryogenic cooling can be enhanced by limiting cooling of target tissues using a thermal barrier disposed between a dual balloon cryotherapy catheter. Containment of both balloons can be monitored by applying a vacuum within a space between the first and second balloons, and by coupling the vacuum space to a fluid shutoff so as to inhibit flow of cryogenic fluid in response to a change in the vacuum space. Controlled cooling of the vessel can be improved by use of a nebulizer in fluid communication with a cryogenic liquid supply lumen and a gas supply lumen.

摘要:
Post-angioplasty hyperplasia in blood vessels is treated using a cryosurgical balloon catheter. The balloon catheter is positioned at a target region within the blood vessel, and the balloon inflated by expanding a cryogenic fluid, such as liquid nitrogen, across an expansion orifice into a balloon. The balloon will be constructed so that cooling is achieved primarily in the central regions of the balloon, with the proximal and distal regions being less cold and acting to insulate adjacent regions of the blood vessel from excessive cooling.
