Abstract: Provided is an apparatus designed to engage tire chains on motorized vehicles when hazardous road conditions are present, including snow or ice. Moreover, the chains are designed to be deployed manually from inoperative to operative positioning by raising and lowering the apparatus handle. A rotating quick deploy chain wheel at the bottom of the apparatus throws a plurality of chains between the tire and road surface generating vehicle traction. This utility patent for tire chains will provide a cost effective, simple method for putting on and taking off snow tire chains. Existing automatic chain systems characteristically require electronics, motors or a pneumatic system. The embodiment of this apparatus is the simplicity of locking a handle and the chains are engaged. Releasing the handle and the chains are disengaged.

Abstract: A system, method and computer program product is provided for caching domain name system (DNS) information on a network gateway. In particular, a network gateway that interfaces one or more customer premises equipment (CPE) devices to an IP network maintains a centralized on-board cache for storing domain names and corresponding IP addresses. The domain names and IP addresses in the cache are used by the network gateway to resolve DNS queries generated by application programs running on the CPE devices in a manner that is transparent to the CPE devices and that does not expend CPE resources. The cache may be initially loaded by an attached CPE or an external network entity and is continuously populated with information extracted from DNS messages exchanged between a CPE device and the external IP network.

Abstract: A system, method and computer program product is provided for selectively caching domain name system (DNS) information on a network gateway. A CPE attached to the network gateway executes an application that searches files in CPE memory to identify frequently accessed domain names. The domain names are used to generate DNS queries that are transmitted by a network gateway to an IP network for resolution. DNS responses are received from the IP network and parsed to extract each resolved domain name and corresponding IP address, which are then stored in a cache on the network gateway. The cache is then used to resolve DNS queries generated by application programs running on the attached CPE.

Abstract: The invention relates to a glass substrate having on at least one of its faces an antireflection coating formed by a stack of thin dielectric material layers having alternately high and low refractive indices. To prevent the modification of the optical properties of the coating in the case where the substrate is subject toga heat treatment such as tempering, bending or annealing, the layer or layers of the stack which are liable to deteriorate on contact with alkali ions such as sodium ions are separated form the substrate by at least one layer forming part of the antireflection coating and forming a “shield” with respect to the diffusion of alkali.

Abstract: A thin film for covering a clear or colored glass sheet to form a monolithic automobile glazing. The film is based upon metallic tantalum. It may be covered with a layer based upon oxides of various metals. The solar energy transmission and also the reflection of light through the glazing are low, whereas the reflectance is similar to that of the base glass.
