An active matrix microfluidic platform employs thin film transistor active (“TFT”) matrix liquid crystal display technology to manipulate small samples of fluid for chemical, biochemical, or biological assays without moving parts, for example, using a two-dimensional matrix array of drive electrodes. The active matrix microfluidic platform may employ existing active matrix addressing schemes and/or commercial “off-the-shelf” animation software to program assay protocols. A feedback subsystem may determine an actual location of a fluid in the microfluidic structure, and provides location information to for display, for example, on an active matrix display, and/or to control movement of one or more fluid bodies in the microfluidic structure.

A system and method of transmitting and receiving RF service signals between a base transceiver station (BTS) of a wireless communication system and subscriber units within a structure. In the forward link, the system demodulates the RF service signal from a BTS to recover a digital service signal; conditions the digital service signal for transmission via the powerline of a structure; and modulates an RF carrier with the digital service signal to generate the RF service signal for wireless transmission to subscriber units within the structure. In the reverse link, the system demodulates the RF service signal from subscriber unit(s) to generate a digital service signal; conditions the digital service signal for transmission via the powerline; and modulates an RF carrier with the digital service signal to generate the RF service signal for transmission to the BTS. Another embodiment eliminates the modulation of an RF carrier with the digital service signal to generate an RF service and vice-versa at the BTS.

A plastic, waveguide-fed, horn antenna is manufactured using a three-dimensional (3D), polymeric micro hot embossing process. Two cavity resonators may be designed to reduce the impedance mismatch between the pyramidal horn antenna and the feeding waveguide. The waveguide-fed antenna may be fabricated using a self-aligned 3D plastic hot embossing process followed by a selective electroplating and sealing process to coat an approximately 8 μm-thick gold layer around the internal surfaces of the system. As such, this plastic, low-cost manufacturing process may be used to replace the expensive metallic components for millimeter-wave systems and provides a scalable and integrated process for manufacturing an array of antenna.

A system and method of determining and reporting on the position of a wireless device relative to a group of other wireless devices dispersed within a specified geographic area. The system includes at least one Query Unit, three or more Responding Units disposed at determinable locations within the specified geographic area, and one or more Mobile Units, which may correspond to additional Responding Units or units that function only as receivers. The Query Unit sequentially queries the Responding Units, and, responsive to the respective query messages, the Responding Units transmit corresponding response messages. One or more of the Mobile Units receive the query and response messages, and generate, for each query-response message pair, a set of time-difference-of-arrival (TDOA) measurements, which are used by the Mobile Units to determine their positions relative to the Responding Units. The Mobile Units record the times-of-arrival (TOAs) of the query message and the response messages at their respective receivers, and calculate the TDOAs based on the recorded TOAs. The TDOAs are then analyzed to determine the time differences due to the differences in lengths of the respective message propagation paths. The position of each Mobile Unit can then be computed using computation techniques typically employed in Long Range Navigation (LORAN) receivers, or any other suitable computation technique.
