摘要:
A nickel stripping composition is disclosed. The composition can be contacted with a nickel plated article in an aqueous solution in order to remove the nickel. In accordance with the present invention, besides an oxidizing agent, the composition includes the combination of an organic amine and citric acid or salt. Alternatively, other amines containing particular substituent groups can be present in the solution in order to increase the nickel holding capacity of the solution.

An anti-theft barrier for an automatic teller machine is provided. The anti-theft barrier has a first post having a sleeve hinge, a second post having a secure locking housing and a rotating barrier arm. The rotating barrier arm has a first end pivoted from the first post and a second end which locks into the housing of the second post. The housing has an internally hidden and protected lock and bolt and an externally penetrating latch. The anti-theft barrier reduces the chances of attack by deterring unauthorized individuals from being able to unlock the rotating barrier arm to potentially damage or illegally remove the automatic teller machine.

A protective cake cover for supporting candles includes a hollow sidewall having an upper end and a lower end, a top cover wall extending across the upper end of the hollow sidewall to define a closed upper end of the protective cake cover, a groove formed in the top cover wall that is configured to support one or more candles that project above the top cover wall, and a recess formed in a central region of the top cover wall and surrounded by the groove, whereby the recess is configured to receive a box that contains candles. The groove has a circular, square, or rectangular shape, and the recess has a square or rectangular shape that is adapted to receive a box of candles that can be stored on the protective cake cover.

The present invention provides system, methods, and apparatus for organizing objects obtained from data retrieval. It provides a method to assemble the objects into a set based upon their relevance ranking, associated metadata including categories, and the proximity of these categories in a graph. The method provides for selecting objects according to estimated difficulty, resource type, media format, or other criteria. It also provides for connecting objects into a best path in the graph. It also provides for selecting objects to fit a desired total duration and coverage of relevant categories in the graph. It also provides for organizing the objects into a particular sequence according to the particular metadata. The system, methods, and apparatus are suitable for use in information systems, learning management systems, and other systems employing data retrieval.
摘要:
A vertical-cavity surface-emitting laser (VCSEL) comprising a low-loss thin metal contact and current spreading layer within the optical cavity that provides for improved ohmic contact and lateral current distribution, a substrate including a plano-concave optical cavity, a (Ga,In,Al)N multiple quantum well (MQW) active region contained within the optical cavity that generates light when injected by an electrical current, and an integrated micromirror fabricated onto the substrate that provides for optical mode control of the light generated by the active region. A relatively simple process is used to fabricate the VCSEL.
摘要:
Scalable platform architecture includes a high bandwidth bus for transmitting data at high bit rates between various video processing subsystems. A graphics processing subsystem, having graphics memory, is coupled to the high bandwidth bus. The graphics processing subsystem is adapted to receive a video memory and to perform video processing when the video memory is received. The high bandwidth bus is provided with expansion connectors for detachably coupling to various subsystems. These subsystems may include a video processing subsystem and a video capture system. The high bandwidth bus is also provided with a bus bridge for coupling the high bandwidth bus to a low bandwidth bus or a central processing unit bus.
