Abstract:
A lamp for providing visible radiation includes tellurium or a tellurium compound in the fill. This substance is present in an amount such that when the fill is excited with sufficient power, substantially all of the radiation resulting from tellurium is emitted at wavelengths exceeding 400 nm. When tellurium is added to a sulfur or selenium based lamp for emitting visible radiation, the spectrum is shifted towards the red region.
Abstract:
An excimer lamp utilizing a high pressure fill. The fill includes a halogen at an operating pressure of greater than about 350 torr or the combination of a halogen and a rare gas at a total operating pressure of greater than about 2.5 atmospheres.
Abstract:
A metal vapor/inert gas laser comprises a laser tube containing an inert gas and a metallic material capable of vaporizing and lasing, a microwave energy source, and a slow wave structure proximate the laser tube for coupling microwave energy from the source to the metal vapor in the laser tube. A non-metallic electronegative species can be substituted for the metallic material in the laser tube.
Abstract:
A user interacts with a data storage service which enables one or more feeds from video and or web cameras to be streamed to the data storage service. The data storage service then provides storage and/or playback services to the subscriber (e.g., for a monthly fee or a usage fee). Once the video streams have been established between at least one camera and the data storage facility, the user may access the recorded data from any one of several sources, such as a world wide web browser or a cellular phone). The interface may provide a matrix of displays such that the user can see multiple areas or multiple parts of the same area simultaneously.
Abstract:
Access Control Lists (ACLs) are used to describe the permitted actions (permissions) on protected network computer system resources or objects associated with an client or user identity. An identity may be an individual user or group of users. The actions are used to represent the different access methods available on a particular projected object or resource. A new action grouping mechanism is provided which tags each action with an action group name. The grouping of actions facilitates a larger permission set to be defined in an ACL, whereas action permission indicators can be reused for unique action definitions within various action groups. This effectively extends the finite total number of permissions available within a security system, allows a more descriptive and extensible permission mechanism in an Access Control List, as well as aiding in the simplification of management and definition of security policies.
Abstract:
Disclosed are methods for conditionally immortalizing stem cells, including adult and embryonic stem cells, the cells produced by such methods, therapeutic and laboratory or research methods of using such cells, and methods to identify compounds related to cell differentiation and development or to treat diseases, using such cells. A mouse model of acute myeloid leukemia (AML) and cells and methods related to such mouse model are also described.
Abstract:
Disclosed are coating compositions that include a polymer comprising silanol functional groups. Also disclosed are substrates coated with such compositions, methods for coating substrates with such compositions, and methods for imparting self cleaning properties to a substrate.
Abstract:
Fiber-reinforced pultruded planks serve as underlayment for tile, stone or terrazzo. In one embodiment, the planks have a thin base surface with a plurality of elongated ridges. The planks have interlocking tongue and groove edges. The elongated ridges have a narrow base and a wider distal portion wherein the areas between adjacent ridges have a trapezoidal cross sectional configuration with the thin base resting on the support. Tile can be adhered to the surface using a rigid cementitious adhesive which fills in the trapezoidal area, creating a very rigid support structure. If the planks are reversed with the ridges resting on the support, tile or stone can be adhered to the relatively smooth thin base with an epoxy adhesive.
Abstract:
A fiber-reinforced pultruded underlayment for ceramic tile includes a thin base with a plurality of elongated ridges. The underlayment is in the form of planks having interlocking tongue and groove edges. The elongated ridges have a narrow base and a wider distal portion wherein the areas between adjacent ridges have a trapezoidal cross sectional configuration. Tile is adhered to the surface using a rigid cementitious or epoxy adhesive which fills in the trapezoidal area creating a very rigid support structure for the ceramic tile.
