Abstract: This disclosure concerns a protective gear with a hood for a user that protects the user from the environment, while also minimizing exposure of the environment to contagious agents, e.g. biological contaminants, that may be exhaled by the user in case the user is infected.

Abstract: A network appliance may be configured to transmit data over a multiple networks from one or more client applications, for example, enterprise business applications. The network appliance may receive and analyze information regarding the multiple different networks transmitting over different transmission media, e.g., terrestrial and wireless, and to switch a client application from a primary network to a backup network based on a detected change in network availability. For example, the determination to switch transmission networks may be based on an outage of a primary network, or based on an efficiency or cost analysis, along with other factors. The network appliance may be in communication with an appliance network server, for example, to receive and compile statistics and remotely reconfigure a plurality of network appliances installed in remote locations.

Abstract: A broadband communication system with improved latency is disclosed. The system employs distributed caching techniques to assemble data objects at locations proximate to a source to avoid latency over delayed links. The assembled data objects are then multicast to one or more remote terminals in response to a request for the objects, thus reducing unnecessary data flow across the satellite link.

Abstract: A positive-pressure respirator hood assembly comprising, a gas-impermeable hood made of a flexible material, formed with at least a transparent visor portion; a gas treatment unit, comprising a filter and a power-operated blower to force air through the filter and generate a positive pressure within the hood; a one-way purge valve for facilitating the exhaust of exhaled gases and moisture from the hood; and a sealing portion for sealingly securing the hood over a body portion of the user; the respirator hood assembly is designed to be compactly received in a container and to be deployed into an operative state automatically, whereby a user is provided protection from toxic gases and particulate material.

Abstract: An insecticidal device is provided which has a panel of a color having insect attracting properties, preferably yellow, and a spherical body of another color, preferably red. The spherical body is capable of defusing a liquid which contains an insect attractant and is combined with the panel in a manner that they form together an essentially flat panel having hemispherical bulges formed by the spherical body. A specific panel, which can be used as a panel in the above device and can be used as an independent insecticidal device is also provided.

Abstract: An axiosymmetric eccentric spherical polycarbonate lens (2) for goggles (1), comprising inner (7) and outer (8) spherical surfaces defined by centers of curvature 0.sub.1 and 0.sub.2 and by radii R.sub.1 and R.sub.2, respectively, 0.sub.1 and 0.sub.2 being both located on the lens's axis of symmetry (5), at a distance D from each other, the lens being more distal from 0.sub.1 than from 0.sub.2, the length of R.sub.2 being about 1.025-1.035 R.sub.1, and that of D about 0.0510-0.0564.
