Abstract: Scattering-type long wave pass filters for the infrared region of the spectrum offer high levels of suppression of the unwanted short-wave radiation, good levels of transmission of the desired long wave radiation combined with good control of the rejection edge position and shape and good mechanical stability of the filter layer. Such filters are well suited for the wide range of applications and can be used in various environments including cryogenic temperatures. Several methods of fabrication of such filters based on electrochemical etching of semiconductor materials in order to form porous layer are provided.

Abstract: Methods are described that have the capability of producing submicron/nanoscale particles, in some embodiments dispersible, at high production rates. In some embodiments, the methods result in the production of particles with an average diameter less than about 75 nanometers that are produced at a rate of at least about 35 grams per hour. In other embodiments, the particles are highly uniform. These methods can be used to form particle collections and/or powder coatings. Powder coatings and corresponding methods are described based on the deposition of highly uniform submicron/nanoscale particles.

Abstract: A technique for sanitizing data storage devices, such as magnetic disks, is disclosed. Logical data storage units such as files or portions thereof may be individually deleted and sanitized on a disk. A disk is divided into physical disk regions, each comprising one or more blocks. The contents of the disk are encrypted using a separate encryption key for each physical disk region. If a file or other data structure located in a first disk region and encrypted using a first encryption key is to be deleted, the logical portions (i.e., blocks) of that region that do not belong to the file are re-encrypted using a second encryption key, and the first encryption key is deleted.

Abstract: A file system in a storage system allows a user to designate data as write-once read-many (WORM) data. The WORM data are stored in a first set of storage media of the storage system. Signature data are generated from the WORM data. Using the signature data, the integrity of the WORM data can be verified.

Abstract: Nanoscale particles, particle coatings/particle arrays and corresponding consolidated materials are described based on an ability to vary the composition involving a wide range of metal and/or metalloid elements and corresponding compositions. In particular, metalloid oxides and metal-metalloid compositions are described in the form of improved nanoscale particles and coatings formed from the nanoscale particles. Compositions comprising rare earth metals and dopants/additives with rare earth metals are described. Complex compositions with a range of host compositions and dopants/additives can be formed using the approaches described herein. The particle coating can take the form of particle arrays that range from collections of disbursable primary particles to fused networks of primary particles forming channels that reflect the nanoscale of the primary particles. Suitable materials for optical applications are described along with some optical devices of interest.

Abstract: This invention provides a specified retention date within a data set that is locked against deletion or modification within a WORM storage implementation. This retention date scheme does not utilize any proprietary application program interfaces (APIs) or protocols, but rather, employs native functionality within conventional file (or other data containers, data sets or block-based logical unit numbers) properties available in commonly used operating systems. In an illustrative embodiment, the retention date/time is calculated by querying the file's last-modified time prior to commit, adding the retention period to this value and thereby deriving a retention date after which the file can be released from WORM. Prior to commit, the computed retention date is stored in the file's “last access time” property/attribute field, or another metadata field that remains permanently associated with the file and that, in being used for retention date, does not interfere with file management in a WORM state.

Abstract: Light reactive deposition can be adapted effectively for the deposition of one or more electrochemical cell components. In particular, electrodes, electrolytes, electrical interconnects can be deposited form a reactive flow. In some embodiments, the reactive flow comprises a reactant stream that intersects a light beam to drive a reaction within a light reactive zone to produce product that is deposited on a substrate. The approach is extremely versatile for the production of a range of compositions that are useful in electrochemical cells and fuel cell, in particular. The properties of the materials, including the density and porosity can be adjusted based on the deposition properties and any subsequent processing including, for example, heat treatments.

Abstract: An apparatus for destroying medical waste material is provided including a transportable container member, a processor having rotatably driven roller members for breaking the medical waste materials into smaller particles, a removable receptacle for containing the medical waste particles, and a loading device for actuating an opening mechanism of the transportable container and regulating the introduction of medical waste material therein.

Abstract: A method and apparatus for automatically providing a display case for a plurality of packages includes an assembly station at which the packages are initially assembled into an array. The array is then moved to a covering station. At the same time, a shroud is formed which shroud covers a top and two opposed first sides of the array while leaving two opposed second sides of the array uncovered. Forming of the shroud includes initially bending a blank so that a partially-formed shroud is produced having a top panel and two opposed side panels formed in a plane, and finally bending and locating the partially formed shroud relative to the array at the covering station such that a fully covered array is provided with the top panel and side panels covering a majority of the respective top and first sides of the array. Finally, the covered array is placed in a tray at a finishing station to provide the display case.

Abstract: An apparatus and method for continuously loading containers into cartons in oriented two row arrays is provided. A supply delivers the containers individually to a depositing device for individually receiving respective containers. The depositing device is then moved to individually deposit the containers delivered thereto in a first collection device for collecting the containers in rows and columns corresponding to the array. The first collection device includes a matrix of dedicated channels similar to the array into which channels the depositing device deposits the containers in a sequential manner whereby the matrix is repeatedly filled with the containers row by row. Individually and alternately after each associated row of the matrix is filled, each row of containers in the first collection device is next delivered to a second collection device for collecting the containers in separated rows. The second collection device includes a respective bay for each respective row of the array of containers.
