A spinal stabilization system generally comprises first and second anchor members configured to be secured to first and second vertebrae within a patient's body, a flexible element secured to the first anchor member, and a rigid element secured to the second anchor member. An end portion of the rigid element is coupled to an end portion of the flexible so that the system is able to provide both rigid and dynamic stabilization. The coupling is maintained even if the flexible element relaxes after a period of time within the patient's body.

The invention discloses a method for enhancing the gas-liquid mass transfer of an ebullated bed hydrogenation reactor, which comprises the following processes of: introducing fresh raw oil, circulating oil and hydrogen into a microbubble generator arranged in front of the reactor, fully mixing to make the hydrogen dispersed in a liquid-phase material in the form of microbubbles, and performing hydrogenation and cracking reaction in the ebullated bed reactor. The method can improve the utilization rate of the hydrogen, reduce the volume ratio of the hydrogen to the oil, save operating cost andpromote the depth of the hydrogenation and cracking reaction.

An improved dry heat method and apparatus for thawing frozen biological fluids utilizing electrically heated plates and oscillatory motion to enhance heat transfer by mixing as the fluid thaws. Bags of frozen fluid to be thawed are lightly squeezed between two heating plates, one of which is gently oscillated to facilitate mixing of the thawing fluid, increasing heat transfer and reducing time required for thawing. Direct contact of the heating plates against the bag surfaces increases heat transfer by eliminating insulative effects of another bag wall and a water boundary layer, compared to water bath units. Flat (or curved to conform to bag) heat pipes are preferred as heating plates compared to plain aluminum sheet. Flat heat pipes have the property of an isothermal heating surface, thus maximizing heat transfer to the coldest areas, preventing hot spots, and simplifying heating plate temperature control.

Multiphasic reactions, especially those reactions using a phase transfer catalyst, are conducted in microchannel apparatus. Advantageously, these reactions can be conducted with two, planar microlayers of reactants in adjacent laminar flow streams. Microchannel apparatus and methods for conducting unit operations such as reactions and separations in microchannel apparatus is also described. Microchannel apparatus can provide advantages for controlling reactions and separating products, solvents or reactants in multiphase reactions.

A method utilizing welds, reinforced with sewn seams, to adhere two fabrics together to form an inflatable airbag cushion. Although welded seams provide better and more easily produced attachment points between multiple layers of fabrics, not to mention improved manners of reducing air or gas permeability as such attachment points, the utilization of sewn seams adjacent to such welded areas provides stronger reinforcement, and thus more reliable non-permeable fabrics. Seam welding generally concerns the utilization of a film on the underside of a fabric which, upon contact with a second, film-treated fabric and upon exposure to high frequency energy, forms a bead of polymeric material at the attachment point between the two fabric layers. Lower numbers of sewn seams may be utilized to permit sufficient reinforcement if the size of the formed polymeric bead if of sufficient size to permit thorough sealing and adhesion between the fabric layers. Such a specific reinforced fabric, as well as high bead-size welded airbag fabrics are encompassed within this invention.

An embodiment is a structure including a first fin over a substrate, a second fin over the substrate, the second fin being adjacent the first fin, an isolation region surrounding the first fin and the second fin, a gate structure along sidewalls and over upper surfaces of the first fin and the second fin, the gate structure defining channel regions in the first fin and the second fin, a source/drain region on the first fin and the second fin adjacent the gate structure, and an air gap separating the source/drain region from a top surface of the substrate.

An electrical terminal connection system includes first and second terminals that are interlocked by placing the first terminal on top of the second terminal and rotating the first terminal. The first terminal has a planar ring section with an outer perimeter and a centrally located aperture. The perimeter has cut-out portions. Inclined spring elements extend from the ring section near the outer perimeter. The second terminal includes a semi-circular part with an outer periphery and a centrally located collar. Curved walls extend perpendicularly from the outer periphery. The walls have ledges projecting over the semi-circular part. Aligning the cut-out portions of the first terminal with the curved walls and ledges of the second terminal enables the planar ring section of the first terminal to be placed on the semi-circular part of the second terminal, with the aperture receiving the collar. Rotating or twisting the first terminal causes the spring elements to contact and slide under the ledges. Simultaneously, a catch extending from the second terminal moves behind a locking edge formed in one of the cut-out portions of the first terminal as a side of the first terminal abuts against one of the curved walls. This prevents further rotation in either direction, maintaining the spring elements in physical and electrical contact with the ledges and interlocking the terminals. Depressing the catch enables reverse rotation and separation of the terminals.

Planar index guided vertical cavity surface emitting laser (PIG VCSEL) utilizes index guiding to provide improved optical confinement and proton implantation to improve current confinement. Index guiding is achieved by etching index guide openings (holes or partial ridges) around the optical confinement region and may be adjusted by varying the etched volume of the index guide openings (holes and partial ridges). The top contact surface area is increased in the PIG VCSEL thereby lowering contact and device resistance to improve VCSEL performance further. The PIG VCSEL is a substantially planarized device for ease of manufacture.
