摘要： A bone anchor insertion device comprises a handle, a nosepiece connected to a distal end of the handle, a bone anchor connected to the nosepiece, and an actuator disposed on the handle for deploying the bone anchor, which suture is also fixed to a portion of soft tissue to be attached to a portion of bone. A suture ratchet or tensioning mechanism is disposed in the handle for tensioning suture which is associated with the bone anchor. This mechanism permits precise tensioning, while also permitting one-handed operation, thereby allowing the practitioner to use his or her other hand for other activities, such as camera operation or the like.

摘要： A bone anchor and methods for using same to secure connective tissue, such as tendons, to bone are disclosed which permit a suture attachment that lies entirely beneath the cortical bone surface. The bone anchor of the invention incorporates a deformable body that creates an increased anchor body diameter after it is inserted into the cancellous bone and deployed beneath the cortical surface of the bone. The increased body diameter, by virtue of its intrinsic geometry, creates both axial and rotational fixation of the bone anchor or suture fixation point.

摘要： A device has first, second and third elements fabricated on a common substrate. The first element supports a first optical mode in a first active waveguide, the second element supports a second optical mode in a second passive waveguide, and the third element, at least partly butt-coupled to the first element, has a bottom waveguide, supporting a bottom intermediate mode, overlying a top waveguide, supporting a top intermediate mode. A tapered waveguide structure in the top waveguide facilitates efficient adiabatic transformation between the top intermediate mode and the bottom intermediate mode. Tapering in at least one of the bottom waveguide and the second waveguide facilitates efficient adiabatic transformation between the second optical mode and the bottom intermediate optical mode. No adiabatic transformation occurs between either of the intermediate optical modes and the first optical mode. Lithographic alignment marks facilitate precise alignment of the three elements during device fabrication.

摘要： A device includes a first element having a passive waveguide structure supporting a first optical mode, a second element providing heat spreading functionality, a third element thermally coupled to the second element, having an active waveguide structure supporting a second optical mode, and a fourth element, at least partly butt-coupled to the third element, having an intermediate waveguide structure supporting intermediate optical modes. A tapered waveguide structure in either one of the first and fourth elements facilitates efficient adiabatic transformation between the first optical mode and one of the intermediate optical modes. No adiabatic transformation occurs between any of the intermediate optical modes and the second optical mode. Mutual alignments of the first, second, third and fourth elements are defined using lithographic alignment marks that facilitate precise alignment between layers formed during processing steps of fabricating the first, second, third and fourth elements.

摘要： A device includes three elements fabricated on a common substrate. The first element includes an active waveguide structure having at least three sub-layers supporting a first optical mode. The second element has a passive waveguide structure supporting a second optical mode, and the third element, butt-coupled to the first element, has an intermediate waveguide structure supporting intermediate optical modes. One sub-layer in the active waveguide structure includes an n-contact layer, another sub-layer includes a p-contact layer, and a third sub-layer includes an active region. A tapered waveguide structure in at least one of the second and third elements facilitates efficient adiabatic transformation between the second optical mode and an intermediate optical mode. No adiabatic transformation occurs between that intermediate optical mode and the first optical mode. Mutual alignments of the three elements are defined using lithographic alignment marks that facilitate precise alignment between layers formed fabrication of the elements.

摘要： A device providing efficient transformation between an initial optical mode and a second optical mode includes first, second and third elements fabricated on a common substrate. The first element includes first and second active sub-layers supporting initial and final optical modes with efficient mode transformation therebetween. The second element includes a passive waveguide structure supporting a second optical mode. The third element, at least partly butt-coupled to the first element, includes an intermediate waveguide structure supporting an intermediate optical mode. If the final optical mode differs from the second optical mode by more than a predetermined amount, a tapered waveguide structure in the second or third elements facilitates efficient transformation between the intermediate optical mode and the second optical mode. Precise alignment of sub-elements formed in one of the elements, relative to sub-elements formed in another one of the elements, is defined using lithographic alignment marks.

摘要： A device comprises first, second and third elements fabricated on a common substrate. The first element comprises an active waveguide structure comprising: one portion, of effective cross-sectional area A1, supporting a first optical mode; and a second portion, butt-coupled to the first portion, of effective cross-sectional area A2>A1. The second element comprises a passive waveguide structure supporting a second optical mode. The third element, at least partly butt-coupled to the second portion, comprises an intermediate waveguide structure supporting intermediate optical modes. If the first optical mode differs from the second optical mode by more than a predetermined amount, a tapered waveguide structure in at least one of the second and third elements facilitates efficient adiabatic transformation between the first optical mode and one intermediate optical mode. No adiabatic transformation occurs between any intermediate optical mode and the first optical mode. Mutual alignments of the elements are defined using lithographic marks.

摘要： Disclosed are methods and systems for improving cell-to-cell repeatability of electrical performance in memory cells. The methods involve forming an electrically non-conducting material having ordered porosity over a passive layer. The ordered porosity can facilitate formation of conductive channels through which charge carriers can migrate across the otherwise non-conductive layer to facilitate changing a state of a memory cell. A barrier layer can optionally be formed over the non-conductive layer, and can have ordered porosity oriented in a manner substantially perpendicular to the conductive channels such that charge carries migrating across the non-conductive layer cannot permeate the barrier layer. The methods provide for the manufacture of microelectronic devices with cost-effective and electrically reliable memory cells.

摘要： A drive belt includes at least one continuous band and a number of cross elements having a transversely curved saddle surface of saddle radius for interacting with an inwardly oriented main face of the continuous band that at a first lateral side thereof adjacent a pillar part of the element connects to a concavely recessed surface part through a first convexely curved transition surface part. The drive belt features include that: a transverse width of the continuous band is larger than that of the saddle surface; the saddle radius is essentially constant throughout the transverse width of the saddle surface; the saddle radius is smaller than a band radius of a transverse curvature of the band in an unloaded state thereof, irrespective of an amount of bending in the longitudinal direction of the band; and the first transition surface part forms a relatively sharp edge.

摘要： A controllable attenuator includes a pair of collimators respectively connected to input and output fibers. A pair of reflection devices are respectively positioned behind the pair of collimators opposite to the corresponding input and output fibers. A U-like light path is defined among the pair of collimators and the pair of reflection devices. A neutral density filter is moveably positioned between the pair of reflection devices wherein a moving direction of the filter is preferably parallel to a longitudinal direction of the pair of collimators. An ND filter position indicator such as a potentiometer, is used to dynamically monitor attenuation setting.
