The optical sensor is positioned between the first and second layers and senses the strain due to the associated load.

A system for redistributing a multiple input audio / video and data signals having a redistributing device equipped to receive signals in a multiple formats and redistribute a selected signal to a user's premises over conductors, preferably existing twisted-pair telephone wire. The redistributing device is in interactive communication with a communications interface located in the user's premises which receives user-input control signals and contains switching circuitry which routes the selected signal to the user's premises where it is received by the receiving unit such as a television receiver. A single redistributing device services an entire multi-user network from a common distribution point, and services multiple users independently. The system of the invention does not interfere with normal use of the telephone network, so users can interactively access services provided by the system and use the telephone at the same time. In one preferred embodiment the system of the invention dynamically allocates frequencies and modulation techniques to various output signals, to maximize spectral efficiency and minimize interference and cross-talk.

Thermochromic liquid crystal filters are fabricated by providing two polarizers oriented at offset polarity with respect to each other; providing alignment structures adjacent the inner surfaces of the polarizers; placing a plurality of spacers between the polarizers; and filling a space created by the spacers with a thermotropic liquid crystal that acts as a depolarizer in a nematic state. The filter acts as a wave block when the liquid crystal is in an isotropic state. Alternatively, the filters can be created by encapsulating a thermochromic liquid crystal with a polymer material to form a flexible film and orienting the thermochromic liquid crystal in the polymer material to create a structure that functions as a thermochromic optical filter. Such filters can control the flow of light and radiant heat through selective reflection, transmission, absorption, and / or re-emission. The filters have particular application in passive or active light-regulating and temperature-regulating films and materials.

This invention is directed to a security system for wireless access points which includes a mounting bracket, an enclosure frame, a lock plate and a locking device. The mounting bracket couples the access point to a stationary surface. The enclosure frame is adapted to be fastened to the mounting bracket and configured to cover the mounting bracket.
