A contact lens assembly includes a proximal layer formed from a gas-permeable material, a distal layer with an optical element, an air cavity disposed between the proximal layer and the distal layer, wherein oxygen concentration across the air cavity is substantially uniform, and an gas transport region surrounding the air cavity for communicating gas between the air cavity and atmosphere. The contact lens assembly may further include a plurality of fins disposed within the air cavity where the plurality of fins has openings therethrough. One or both of the upper and lower surfaces of the air cavity may have an anti-reflection coating formed thereon.

An adjustable cervical collar designed to accommodate a broad range of prospective wearers with unique physical attributes, and to restrict the movements of the wearer's cervical spine, including rotation, flexion, extension, and lateral bending. The cervical collar includes a front portion and back portion, which may be adjusted in relation to one other to vary the circumference of the cervical collar. The front portion includes upper and lower plastic portions which may be adjusted to vary the height of the cervical collar, and a front thoracic extender which may be adjusted to achieve a desired restrictiveness of flexion movement. The back portion includes occipital and back thoracic extenders which may be adjusted to achieve a desired restrictiveness of extension movement. The adjustable features may be operated independently of one another. The adjustable features include locking means to ensure that the cervical collar is securely applied to the wearer.

A semiconductor memory device has a timing margin for internal operations. The semiconductor memory device can activate an internal control signal for controlling an external address sooner than an internal control signal for controlling an external command to secure a sufficient time for data access. The semiconductor memory device includes a command decoding circuit configured to decode an external command to output an internal command signal for an internal operation corresponding to the external command, a control circuit configured to generate a strobe signal for controlling the internal operation in response to the internal command signal and an internal address signal by decoding an address signal received from outside such that the internal address signal activates sooner than the strobe signal, and a column decoding circuit configured to generate a data access signal when both the internal address signal and the strobe signal are activated.

An auxiliary engine warming system for a primary engine in a diesel locomotive including: a modular engine assembly including an auxiliary diesel engine, the assembly displaceable as a unit from and to a frame for the engine warming system; an auxiliary fuel tank including a fuel line detachably connected to the auxiliary engine and including a first fitting detachably connectable to a first fuel line for a fuel tank for the diesel; at least one temperature sensor interfacable with the diesel locomotive and arranged to monitor at least one temperature condition for the diesel locomotive; and an emergency dialer for automatically dialing a preprogrammed number and transmitting an alert message in response to an alarm signal from the at least one temperature sensor.

A method of biotreating a solid material to remove an undesired compound using a nonstirred surface bioreactor is provided. According to the method the surface of a plurality of coarse substrates is coated with a solid material to be biotreated to form a plurality of coated coarse substrates. The coarse substrates have a particle size greater than about 0.3 cm and the solid material to be biotreated has a particle size less than about 250 mum. A nonstirred surface reactor is then formed by stacking the plurality of coated coarse substrates into a heap or placing the plurality of coated coarse substrates into a tank so that the void volume of the reactor is greater than or equal to about 25%. The reactor is inoculated with a microorganism capable of degrading the undesired compound in the solid material, and the solid material is then biotreated in the surface bioreactor until the undesired compound in the solid material is degraded to a desired concentration. Preferably the thickness of the solid material coating on the plurality of coarse substrates is less than about 1 mm and the void volume of the reactor is greater than or equal to about 35%. The process is useful for many different biotreatment processes, including the bioremediation of contaminated soils, the desulfurization of coal, and the biooxidation of refractory sulfide ores and concentrates. In bioremediation applications, the undesired compound is typically an organic compound. In coal desulfurization and refractory sulfide ore biooxidation applications, the undesired compound is sulfide minerals.

Embolic protection elements are integrated with a catheter or access sheath for any catheter. A catheter with an integrated embolic protection element comprises a catheter shaft, an embolic filter slidably mounted on a distal portion of the shaft, a proximal stop for limiting the proximal movement of the embolic filter, and a distal stop for limiting the distal movement of the embolic filter. The filter comprises a porous mesh material defining a collection chamber for captured emboli and has a collapsed and a deployed configuration. The filter may be collapsed by an access sheath used with the catheter. An access sheath may comprise a tubular main body and an embolic filter mounted on the distal portion of the tubular main body. The embolic filter may evert into the central lumen of the sheath or may be constrained on the exterior of the sheath with a larger diameter outer tube.

A latchable package comprises: a support for supporting one or more items; a structure for selectively blocking access to the one or more items; and a latchable insert. The latchable insert comprises a substantially planar tab member that is coupled to the support such that the insert and support are movable together in an opening direction from a first position in which the structure blocks access to the one or more items to a second position in which the one or more items are accessibly clear of the structure. The structure and the latchable insert comprise co-operating latch features configured to engage when the insert and support are arranged in the first position.

A method for cooling power electronics circuits, in which a printed circuit board is produced according to a prescribed circuit board process and is populated with at least one power electronics components. Contact connecting at least one location on at least one metallic conductor track running on a surface of the printed circuit board that includes at least one metal element, which is both electrically conductive and heat-conductive and the physical height of which is designed to be at least as large as that of the at least one power electronics component. A cooling plate is placed in a planar manner onto the at least one power electronics component and / or the at least one metal element.
