Abstract: A method of fabricating a solar cell is disclosed. The method includes forming a polished surface on a silicon substrate and forming a first flowable matrix in an interdigitated pattern on the polished surface, where the polished surface allows the first flowable matrix to form an interdigitated pattern comprising features of uniform thickness and width. In an embodiment, the method includes forming the silicon substrate using a method such as, but not limited to, of diamond wire or slurry wafering processes. In another embodiment, the method includes forming the polished surface on the silicon substrate using a chemical etchant such as, but not limited to, sulfuric acid (H2SO4), acetic acid (CH3COOH), nitric acid (HNO3), hydrofluoric acid (HF) or phosphoric acid (H3PO4). In still another embodiment, the etchant is an isotropic etchant. In yet another embodiment, the method includes providing a surface of the silicon substrate with at most 500 nanometer peak-to-valley roughness.

Abstract: The present teachings provide one or more surgical implements for repairing damaged tissue, such as in the case of a spinal fixation procedure. A cross connector system for use during a spinal fixation procedure is provided. The system includes at least one bridge defining a coupling bore and having a pair of downwardly extending arms for coupling to a first bone engaging member. The system includes a contoured bar having a first end offset from a second end, and a bore having a central axis. The system includes an expansion ring received within the bore, and a locking device received through the expansion ring and the coupling bore. The locking device is operable in a first state in which the contoured bar is movable about the central axis of the bore and in a second state in which the contoured bar fixed relative to the central axis of the bore.

Abstract: Methods of fabricating solar cells and apparatuses for fabricating solar cells are described. In an example, a method of fabricating a solar cell includes treating a light-receiving surface of a substrate with a gaseous ozone (O3) process. Subsequently, the light-receiving surface of the substrate is texturized.

Abstract: A remote control system includes a first network configured for communication via a first format. The first network includes a router configured to receive packetized remote control codes transmitted to the router in the first format. The remote control system further includes a second network configured for communication via a set of second formats. The second network includes a translator communicatively coupled to the router via a network link The translator is configured to receive the packetized remote control codes from the router in the first format and translate the remote control codes from the first format to a set of second formats. The second network further includes a blaster communicatively coupled to the translator. The blaster is configured to received the packetized remote control codes in the set of second formats and transmit the packetized remote control codes in the set of second formats to a set of consumer-electronic devices.

Abstract: An intervertebral implant for insertion between adjacent vertebral bodies is provided. The intervertebral implant can include a first component including a first articulating surface, which can be generally convex with a first radius of curvature. The first articulating surface can also define a stop element. The intervertebral implant can comprise a second component defining an aperture and including a second articulating surface. The second articulating surface can be generally concave and can have a second radius of curvature. The second articulating surface can be articulable with the first articulating surface for retaining motion between the first and second vertebra. A portion of the first articulating surface including the stop element can extend into the aperture and contacts a sidewall of the aperture to limit the range of articulation of the first component and the second component.

Abstract: An intervertebral implant for insertion between adjacent vertebral bodies is provided. The intervertebral implant can include a first component. The first component can have a first articulating surface, which can be generally convex. The intervertebral implant can include a second component, which can be generally in the shape of a toroid. The second component can have a second articulating surface. The second articulating surface can be generally concave and articulable with the first articulating surface for retaining motion between the first and second vertebra. The second articulating surface can have a larger radius of curvature than the first articulating surface such that a portion of the first articulating surface extends into an aperture defined by the generally toroid shape.

Abstract: Single use or disposable cutting blocks and methods for utilizing same are disclosed. The blocks are preferably constructed of polymer and/or other suitable low cost and light weight materials. The blocks may be adapted for use with low friction cutting instruments, as well as other such cutting instruments. Several differently sized and configured blocks may be utilized to perform a single surgical procedure. In addition, kits housing one or more such blocks, with or without other instruments are possible.

Abstract: Methods, systems, and computer readable media for facilitating trading two items (L,Q) from the group of items comprising commodities and financial instruments. At least two agents (2) want to trade the items (L,Q). There is a trading channel (3) between the two agents (2) allowing for the execution of trades. There are flow (trading) limits on the items being traded. A central computer (1) is coupled to the two agents (2). Said computer (1) is adapted to convey to each agent (2) current tradable bid and offered prices and sizes subject to the agent's (2) trading limits.

Abstract: An apparatus for guiding a surgical instrument for shaping the end of a bone includes an alignment plate which has a contact surface and is mounted with the contact surface in a plane substantially perpendicular to the physical axis of the bone and in contact with the bone. A cutting guide is mounted to the alignment plate for rotation about an axis which is substantially parallel to the mechanical axis. The cutting guide includes an instrument-receiver which maintains the surgical instrument in a cutting plane which is substantially parallel to the contact plane and at a predetermined distance from it.
