| 20110134335 | Multimode filter architecture - Systems and methods which provide a multimode tuner architecture implementing direct frequency conversion are shown. Embodiments provide a highly integrated configuration wherein low noise amplifier, tuner, analog and digital channel filter, and analog demodulator functionality are provided in a single integrated circuit. A LNA of embodiments implements a multi-path configuration with seamless switching to provide desired gain control while meeting noise and linearity design parameters. Embodiments of the invention implement in-phase and quadrature (IQ) equalization and a multimode channelization filter architecture to facilitate the use of direct frequency conversion. Embodiments implement spur avoidance techniques for improving tuner system operation and output using a clock signal generation architecture in which a system clock, sampling clock frequencies, local oscillator (LO) reference clock frequencies, and/or the like are dynamically movable. | 06-09-2011 |

| 20120085414 | ROTARY FLUID VALVE ASSEMBLIES, SYSTEMS AND METHODS - Rotary valves are provided having an elongate spool defining coaxially aligned inlet and outlet ports for respectively receiving and discharging a fluid, and spool inlet and outlet orifices. A rotary cage assembly defines an annular cage recess and cage inlet and outlet orifices in communication with the recess and coaxially surrounds the spool for reciprocal rotations thereabout. An actuator assembly is coupled to the rotary cage assembly for moving the rotary cage assembly between open and closed positions. When in the open position the cage inlet and outlet orifices are in fluid communication with the spool inlet and outlet orifices, respectively, to allow fluid to flow from the spool inlet port to the spool outlet port by way of the annular cage recess. When in the closed position however fluid communication is blocked between at least the cage and spool outlet orifices. | 04-12-2012 |

| 20100033577 | VIDEO SURVEILLANCE AND REMOTE MONITORING - A housing for at least three adjustably fixed cameras and at least one pan/tilt/zoom camera may include a bottom wall having a bottom opening and a dome protruding through the bottom opening, where the dome may be configured to house at least a portion of the at least one pan/tilt/zoom camera. The housing may further include a number of side walls including first, second, and third side walls adjacent to the bottom wall and disposed at obtuse angles in reference to the bottom wall. The first, second and third side walls may also have openings disposed in line with the viewing angles of the fixed cameras. The housing may also include a fourth side wall adjacent to the bottom wall. | 02-11-2010 |

| 20100143694 | PROCESS FOR THERMOFORMING ACRYLIC POLYMER EMPLOYING FOAM AS A MOLD AND ARTICLE FORMED THEREFROM - The present invention is directed to a process of thermoforming an acrylic polymer containing sheet by heating the sheet in a mold which comprises (a) a foam which would degrade if in contact with the heated sheet and (b) a thermal barrier which is intermediate the sheet and foam to prevent the foam from degrading. In many applications, the resulting article can be used without removal of the foam. Also, the foam can serve to protect the acrylic sheet such as during long distance shipping. | 06-10-2010 |

| 20100243753 | Gas Dynamic Virtual Nozzle for Generation of Microscopic Droplet Streams - A nozzle for producing a single-file stream of droplets of a fluid, methods using the nozzle, and an injector, comprising the nozzle of the invention, for providing the single-file stream of droplets of a fluid to a high-vacuum system are described. The nozzle comprises two concentric tubes wherein the outer tube comprises a smoothly converging-diverging exit channel and the outlet end of the first tube is positioned within the converging section of the exit channel. | 09-30-2010 |
