Abstract: A transponder has a resonant RLC circuit with one or more electromagnetic energy storage components that vary in response to an externally applied modulating energy field. In addition to the externally modulating energy field, a base station transmits a carrier signal with a frequency essentially the same as the quiescent resonant frequency of the RLC circuit. As the component(s) vary, the resonant frequency of the RLC circuit changes, modulating the carrier signal with the external modulating energy field. Effects of the modulation are detected by the base station. Information (e.g., the presence of a tag) is obtained by receiving and demodulating the modulated signal at the base station. One or more or the circuit elements (e.g, different preferred embodiments of one or more capacitors, inductors, and resistors) can be varied (e.g. mechanically) to modulate the carrier signal.

Abstract: Liquid crystal display (LCD ) panels can be formed rapidly by this method, which involves depositing liquid crystal (LC) in a central region of one substrate, depositing a fillet of epoxy material in a continuous loop along the periphery of one substrate to surround the LC material, placing a second glass substrate over the first substrate and in continuous contact with the epoxy fillet, and then causing the fillet to set by curing or cross-linking. Advantageously, the epoxy fillet can be hardened by scanning it with an infrared or ultraviolet laser focussed to avoid heating the LC material. Alternatively, the epoxy fillet can be formed from two-component epoxy by depositing one fillet of each component on the peripheral region of one of the substrates, joining the substrates to merge the two components, and then vibrating the joined substrates to enhance commingling and setting of the two components into a strong hermetic seal.

Abstract: A device and method for maintaining the volume of a liquid contained within a cavity between two substrates to something equal or nearly equal to that of the volume of the cavity. A particular application is a liquid crystal display (LCD), in which a liquid crystal (LC) material is contained within a cavity between two flat display substrates. The device serves to minimize the volume differential between the liquid and the cavity caused by a change in temperature of the display, such that the formation of bubbles within the liquid is substantially or completely prevented. In so doing, the device essentially eliminates thermally-induced defects that would otherwise be visible to the user.
