    摘要： A system and method are provided for modifying the effective reading range of an radio frequency identification tag. The tag, a chip-based tag, includes an antenna and a chip in communication with the antenna. The chip includes circuitry including field effect transistors that can modify the effective reading range of the tag by modifying characteristics of the tag including the modulation depth of the backscatter signal, the impedance characteristics of the tag front end electronics, the power consumption characteristics and the threshold power-on voltage of the tag. These characteristics are change either temporarily or permanently in response to commands communicated to the tag from a radio frequency identification reader.

    摘要： An electro-optical memory cell having a non-volatile programmable refractive index and a method of making. The memory cell includes: a waveguiding structure having a transition metal oxide with oxygen vacancies; a plurality of electrodes for applying an electrical field; and an optical detector for detecting a state of the memory cell. The method includes: fabricating a waveguiding structure having a transition metal oxide with oxygen vacancies; positioning a plurality of electrodes for application of an electric field; arranging the transition metal oxide and the electrodes such that when an electric field is applied, the oxygen vacancies migrate in a direction that has a component which is radial relative to a center of the beam path; applying the electric field thereby programming the refractive index to set a state of the memory cell; and detecting the state of the memory cell using an optical detector.

    摘要： An occupant of a cubicle or office can activate transparent partitions to partially or completely enclose a cubicle and/or office to minimize noise, optimize privacy, lighting, air flow and temperature. This transparent partition is coated with a thin layer material connected to electrodes. Once the occupant decides that changing working conditions (e.g., minimize noise, optimize privacy, adjust lighting, air flow and/or temperature) is needed, the occupant can activate the thin transparency control layer by appropriate electronic control. Movable parts of the partitions may also be adjusted. The transparent partitions may be made darker or opaque. Movable partitions may be used to provide optimized privacy, noise level, lighting, air flow and temperature control. Conversely, the partitions may be made transparent and movable sections retracted to permit greater worker-to-worker interaction.
