Preventing rogue implementations of a security-sensitive class interface
A method and apparatus for preventing rogue implementations of a security-sensitive class interface are provided. With the method and apparatus, a unique identifier (UID) is created by a server process when the server process is started. Anytime the server process, i.e. a server runtime environment, instantiates a new credential object following start-up of the server process, the encrypted UID is placed into a private field within the new credential object. In addition, the UID is encrypted and stored in a private class of the server runtime environment. A verification class is provided within the server runtime environment which includes one or more methods that receive the credential object as a parameter and return true or false as to the validity of the credential object. These one or more methods determine the validity of the credential object by retrieving the encrypted UID from the private class stored in the server runtime environment, decrypting the UID and comparing it to the decrypted UID stored in the private field of the credential object. If the two UIDs match, a determination is made that the credential object was created by the server runtime environment rather than a rogue application. If the two UIDs do not match, or if there is no UID in the credential object, then a false result will be returned by the verification class. |

Cache management using historical access information
A caching manager calculates cache priorities for accessed items, including items not currently stored in the cache. The cache manager determines an item's cache priority as a function of the item's access frequency, retrieval cost and size. The cache manager dynamically updates cache priorities as items are accessed. When the cache is full and a non-cached item is accessed, the cache manager uses cache priorities to determine whether to overwrite a cached item with the non-cached accessed item. If the accessed item has a lower cache priority than all of the items in the cache, then the non-cached item is not stored in the cache. If any item in the cache has a lower cache priority than the accessed item, then the cache manager stores the accessed item in the cache, overwriting the cached item with the lowest cache priority. |

The RAID class driver binds a RAID-specific functional interface to each disk having a RAID-specific device identification and combines the disks into a disk object representing the entire RAID system. The disk object provides the operating system with a standard disk device identification. The operating system loads a standard disk driver to interface with the disk object, thereby enabling transparent access to the RAID system. |

Data storage using disk drives in accordance with a schedule of operations
Techniques for data storage using disk drives. To conserve power and reduce heat generation so that higher packaging density is possible, only some of the disk drives in an array may be powered on at any one time. Disk accesses may then be scheduled so that appropriate drives are powered on and off at appropriate times. In addition, various levels of storage services may be provided depending, for example, upon how accessible the drives are to individual clients and upon a level of data redundancy provided. Another advantage includes off-loading of tasks to a controller or processor included within the disk drives themselves. For example, the disk drives themselves may compute error detection or error correction representations and perform data integrity checks based on those representations. Failure simulation may also be performed to verify the ability to recover lost data and the disk drives may be used to convert the data into general formats that may be expected to be more easily read in the future. |

Pseudo random and command driven bit compensation for the cycling effects in flash memory
Easily implemented randomization within a flash memory EEPROM reduces the NAND string resistance effect, program disturbs, user read disturbs, and floating gate to floating gate coupling that result from repeated and long term storage of specific data patterns. The randomization may be code generated pseudo randomization or user driven randomization in different embodiments. User driven commands, the timing of which cannot be predicted may be used to trigger and achieve a high level of randomization. Randomly altering the encoding scheme of the data prevents repeated and long term storage of specific data patterns. Even if a user wishes to store the same information for long periods, or to repeatedly store it, it will be randomly encoded with different encoding schemes, and the data pattern will therefore be varied. |

Method and system for structured programmed input/output transactions
Disclosed is a structured model for developing PIO code and for performing PIO transactions. This model of structured PIO transactions provides a framework with default behaviors. Developers need only provide a minimal amount of configuration information and can then characterize subsequent PIO transactions in terms of a profile, thus reducing the amount of detailed and often redundant information that developers need to provide for each PIO transaction.

Method for providing a DNS server address list from a server to a client
The invention relates to a method for providing a DNS server address list from a server 1 to a client 2 comprising the steps of: the client 2 requests an IP address from the server 1; and the server 1 responds by assigning the IP address together with said DNS address list to the client 1. In the prior art the order of the DNS server addresses in the list is static, that means that upon any IP request the same list, having the same order of addresses is provided to the client. When the client wants to output a DNS request he starts by asking the first server in the list irrespective as to whether said server may currently be overloaded or has gone down. In these situations time is lost since no response is provided by such a disturbed DNS server to a DNS request and the client has to ask another server in the list. In order to overcome these disadvantages the order of the DNS server addresses in the list is dynamically updated in that the client always knows which of the available DNS servers is currently best appropriated. |

High throughput functional genomics
This invention focuses on the marriage of solid-state electronics and neuronal function to create a new high-throughput electrophysiological assay to determine a compound's acute and chronic effect on cellular function. Electronics, surface chemistry, biotechnology, and fundamental neuroscience are integrated to provide an assay where the reporter element is an array of electrically active cells. This innovative technology can be applied to neurotoxicity, and to screening compounds from combinatorial chemistry, gene function analysis, and basic neuroscience applications. The system of the invention analyzes how the action potential is interrupted by drugs or toxins. Differences in the action potentials are due to individual toxins acting on different biochemical pathways, which in turn affects different ion channels, thereby changing the peak shape of the action potential differently for each toxin. Algorithms to analyze the action potential peak shape differences are used to indicate the pathway(s) affected by the presence of a new drug or compound; from that, aspects of its function in that cell are deduced. This observation can be exploited to determine the functional category of biochemical action of an unknown compound. An important aspect of the invention is surface chemistry that permits establishment of a high impedance seal between cell and a metal microelectrode. This seal recreates the interface that enables functional patch-clamp electrophysiology with glass micropipettes, and allows extracellular electrophysiology on a microelectrode array.

Sub-threshold stimulation to precondition neurons for supra-threshold stimulation
In order to generate the smallest phosphenes possible, it is advantageous to selectively stimulate smaller cells. By hyperpolarizing the somas of the large cells selectively with sub-threshold anodic ‘pre-pulse’ stimuli (making them more difficult to stimulate) and then selectively depolarize the smaller cells one can selectively stimulate smaller cells. Alternatively, one can hyperpolarize the dendrites of the cells with larger dendritic fields by applying sub-threshold anodic currents on surrounding electrodes and then depolarizing the smaller cells in the center. Further, one can manipulate the phases of an individual biphasic wave to affect selective stimulation resulting in more focal responses. It is possible to increase resolution with the ‘pre-pulse’ described above. One can also effect resolution by modifying the pulse order of the cathodic and anodic phases. Further, one can isolate the effect of the phases by separating them in time (long inter-phase interval) or by making one of the phases long and low amplitude—always keeping equal total charge for the two phases. As an example, one can preferentially stimulate smaller ganglion cells by providing a longer sub-threshold anodic pulse balanced with a shorter supra-threshold cathodic pulse. Preferentially stimulating the smaller ganglion cells will allow stimulation of different brightness levels while maintaining high spatial resolution. |

Breathing and aberration variation during focusing are optionally controlled by moving at least two groups of lens elements independently. Aberration correction in general is aided by allowing the working distance to become short relative to the format diagonal. Field curvature is largely corrected by a steeply curved concave surface relatively close to the image plane. This allows the main collective elements to be made of low-index anomalous dispersion materials in order to correct secondary spectrum. In wide-angle example embodiments, distortion may be controlled with an aspheric surface near the front of the lens. |

Phosphor screen and displays systems
A phosphor screen for image forming including phosphor material being excitable by light in a wavelength λ1. The phosphor screen receives an optical image from an image forming optical system and produces the optical image at a second wavelength λ2. The phosphor screen includes a phosphor layer comprising the phosphor material. A short-pass reflective coating is positioned on a first side of the phosphor layer. The short-pass reflective coating transmits the wavelength λ1 and reflects the wavelength λ2. A long-pass reflective coating is positioned on a second side of the phosphor layer. The long-pass reflective coating transmits the wavelength λ2 and reflects the wavelength λ1. A first substrate is positioned over the short-pass reflective coating. The first substrate is formed of optically clear and thermal conductive material. A second substrate is positioned over the long-pass reflective coating. The second substrate is formed of long-pass absorptive optical filter material that transmits the wavelength λ2 and absorbs wavelength λ1 from ambient light to prevent the phosphor layer from being excited by the ambient light. The phosphor screen may alternatively be used for a direct-view visual display apparatus. These principles can also be utilized for backlighting and general illumination applications. |

Method and apparatus for reducing microlens surface reflection
A microlens has a surface with an effective index of refraction close to the index of air to reduce reflection caused by change in indices of refraction from microlens to air. The microlens having an index of refraction approximately the same as that of air is obtained by providing a rough or bumpy lens-air surface on the microlens. Features protrude from the surface of a microlens to create the rough surface and preferably have a length of greater or equal to a wavelength of light and a width of less than a sub-wavelength of light, from about 1/10 to ¼ of the wavelength of light. The features may be of any suitable shape, including but not limited to triangular, cylindrical, rectangular, trapezoidal, or spherical and may be formed by a variety of suitable processes, including but not limited to mask and etching, lithography, spray-on beads, sputtering, and growing. |
