Multimedia surveillance and monitoring system including network configuration

A comprehensive, wireless multimedia surveillance and monitoring system provides a combination of megapixel digital camera capability with full motion video surveillance with a network, including network components and appliances such as wiring, workstations, and servers with the option of geographical distribution with various wide area carriers. The full service, multi-media surveillance system is capable of a wide range of monitoring techniques utilizing digital network architecture and is adapted for transmitting event data, video and / or image monitoring information, audio signals and other sensor and detector data over significant distances using digital data transmission over a LAN, wireless LAN, Intranet or Internet for automatic assessment and response including dispatch of response personnel. Both wired and wireless appliance and sensor systems may be employed. GPS dispatching is used to locate and alert personnel as well as to indicate the location of an event. Automatic mapping and dispatch permits rapid response. The wireless LAN connectivity permits local distribution of audio, video and image data over a relatively high bandwidth without requirement of a license and without relying on a common carrier and the fees associated therewith. The surveillance system may be interfaced with a WAN (wide area Network) or the Internet for providing a worldwide, low cost surveillance system with virtually unlimited geographic application. Centralized monitoring stations have access to all of the surveillance data from various remote locations via the Internet or the WAN. A server provides a centralized location for data collection, alarm detection and processing, access control, dispatch processing, logging functions and other specialized functions. The server may be inserted virtually anywhere in the Intranet / Internet network. The topology of the network will be established by the geographic situation of the installation. Appropriate firewalls may be set up as desired. The server based system permits a security provider to have access to the appliance and sensor and surveillance data or to configure or reconfigure the system for any station on the network.

Non-flat liquid crystal display element and method of producing the same

Disclosed is a non-flat liquid crystal display (LCD) element having a liquid crystal, a sealing wall and paired substrates opposed to each other such that a major surface of the LCD element has a non-flat form. In an aspect, spacers are disposed between the substrates, and a spacer density in a predetermined region is different from that in at least a portion of the other region. In another aspect, resin structures are disposed between the substrates and are adhered to the substrates, and a resin structure adhesion area, per unit area of the substrate, with respect to the substrate in a predetermined region is different from that in at least a portion of the other region. In further another aspect, at least one of pixel form, size and arrangement pitch in a predetermined region is different from that in at least a portion of the other region. In further another aspect, the resin structures are disposed between the substrates, and at least one of resin structure form, size and arrangement pitch in a predetermined region is different from that in at least a portion of the other region. Also disclosed is a method of producing a non-flat LCD element. The method includes the steps of: holding a liquid crystal between paired flat substrates to produce a flat LCD element having an entirely flat form; and deforming the flat LCD element into a predetermined non-flat form.
