| 20090052049 | FLUIDIC OPTICAL DEVICES - A fluidic optical device, systems utilizing fluidic optical devices, methods for manufacturing fluidic optical devices and actuators are disclosed. | 02-26-2009 |
| 20110007161 | FLUIDIC OPTICAL DEVICES - A variable focal length lens sensor system for use with UAVs is disclosed. A variable focal length lens camera for use with cell phones. One or more static optical components and one or more are within a housing. The variable focal length lens includes a sidewall and first and second optical surfaces defining an aperture. One or more of the optical surfaces are at least partially elastic. One or more lens fluids are disposed between the aperture and sidewall. An actuator is configured to apply a force to a portion of the variable focal length lens. The applied force results in a change in focal length of the variable focal length lens. The combination of static optical components and variable focal length lenses are capable of providing variable zoom and focus. An image sensor is optically coupled to the variable focal length lens for capturing images. Control electronics are configured to control the fluidic lens and sensor. | 01-13-2011 |

| 20100138639 | SANDBOXED EXECUTION OF PLUG-INS - A sandbox architecture that isolates and identifies misbehaving plug-ins (intentional or unintentional) to prevent system interruptions and failure. Based on plug-in errors, the architecture automatically disables and blocks registration of the bad plug-in via a penalty point system. Publishers of bad plug-ins are controlled by disabling the bad plug-ins and registering the publisher in an unsafe list. Isolation can be provided in multiple levels, such as machine isolation, process isolation, secure accounts with limited access rights, and application domain isolation within processes using local security mechanisms. A combination of the multiple levels of isolation achieves a high level of security. Isolation provides separation from other plug-in executions and restriction to system resources such as file system and network IP. Moreover, the architecture is highly scalable, stateless, and low administration architecture for the execution of the plug-ins, which can be scaled by adding/removing additional sandbox servers on-the-fly without prior configuration. | 06-03-2010 |

| 20090243750 | BALUN WITH SERIES-CONNECTED BALANCED-SIGNAL LINES - A balun may include series-coupled balanced-signal lines. In some examples, a balun may include a first transmission line having a first unbalanced signal port on which an unbalanced signal may exist relative to circuit ground; a second transmission line having a first balanced-signal port may be connected in series with a third transmission line having a second balanced-signal port. In some examples, a fourth transmission line may be coupled to the first transmission line and have a third balanced-signal port. A fifth transmission line may be connected in series with the fourth transmission line and have a fourth balanced-signal port. In some examples, the transmission lines may be coaxial. Balanced signals may exist between the first and second balanced-signal ports and between the third and fourth balanced-signal ports. Series-connected coaxial transmission lines may be formed of a single coaxial line with a gap in the outer conductor separating the two coaxial transmission lines. | 10-01-2009 |
| 20100301963 | BALUN WITH INTERMEDIATE CONDUCTOR - A balun comprising first and second transmission lines having a shared intermediate conductor. The first transmission line may include first and second conductors. The first conductor may have a first end for conducting an unbalanced signal relative to a circuit ground and a second end for conducting a balanced signal. The second conductor may have first and second ends proximate the respective first and second ends of the first conductor. The first end of the second conductor is open circuited. The second transmission line may include the second conductor and a third conductor having a first end connected to circuit ground and a second end for conducting the balanced signal. A resistor may connect the second end of the second conductor to circuit ground. | 12-02-2010 |
| 20110074519 | TRANSMISSION-LINE TRANSFORMER - An example of a transmission-line transformer may include a transmission-line assembly and a balun assembly. The transmission-line assembly may include first and second conductors forming at least first and second transmission-line sections. The transmission-line assembly may provide a signal path through the first conductor and second conductor in series to a circuit ground. Balanced lines of the balun assembly may be connected to respective intermediate points on the first and second conductors between the first and second transmission-line sections. The transmission-line transformer may provide a signal path between a first end of the first conductor of the transmission-line assembly and the unbalanced line of the balun assembly. | 03-31-2011 |
