| 20080314381 | Positive locking device for snorkels, scuba regulators and the like - Positive locking device for components of snorkels and other equipment such as diving regulators, buoyancy compensator hoses and the like. The locking device in a preferred embodiment comprises a hard plastic C-shaped ring or clamp which is preferably mechanically and/or chemically bonded into a soft plastic component connector during molding of that component. The ring or clamp provides an effective locking feature which prevents inadvertent demating of components during a dive or other activity that could otherwise result in a dangerous loss of function. An additional embodiment of the invention provides an optional indexing feature which serves the useful function of audible and tactile feedback during adjustment of components having the locking device. | 12-25-2008 |

| 20100010447 | FLUSH ENTRANCE HEMOSTASIS VALVE WITH UNOBSTRUCTED PASSAGEWAY - A method of placing a catheter into a patient while preventing disadvantageous escape of fluid from the patient comprises providing a catheter secured to a valve hosing. The catheter has a proximal end, a distal end and an interior lumen. The valve housing has a first port, a second port, and a fluid path running between the first and second ports. The catheter and the valve housing have a hollow needle extending therethrough. The method further comprises piercing the patient's skin, thereby inserting the catheter into the patient. The method further comprises holding the catheter and valve housing in place while removing the hollow needle through the catheter and valve housing. The hollow needle passes through the first and second ports of the valve housing. | 01-14-2010 |

| 20100053330 | SECURITY SYSTEM USING LADAR-BASED SENSORS - A security sensor system comprises one or more laser detection and ranging (LADAR) sensors configured for accumulation of three-dimensional image data. In one embodiment, the one or more LADAR sensors each comprise a LADAR device, such as a MEMS device, configured to transmit a plurality of laser pulses, and a microprocessor operatively coupled to the LADAR device. One or more data storage devices is operatively coupled to the microprocessor and configured to store the three-dimensional image data, as well as predetermined protected area boundary and fixed object definitions. A GPS receiver can be operatively coupled to the microprocessor and a GPS antenna. The microprocessor is configured to perform a LADAR image analysis that compares the three-dimensional image data with the protected area boundary and fixed object definitions to identify one or more potential intruders. | 03-04-2010 |
| 20110021231 | SYSTEM AND METHOD OF AUTOMATICALLY MAINTAINING A LINE-OF-SIGHT COMMUNICATION CHANNEL - One exemplary embodiment is directed to a method of automatically maintaining a line-of-sight communication channel. The method comprises determining information about each communication resource that is accessible in a region through which a mobile system is moving. The method further comprises determining information about the mobile system. The method further comprises performing a line-of-sight (LOS) analysis for each of the communication resources based at least in part on a respective location and a respective elevation for the respective communication resource and the current location of the mobile system and a current elevation for the mobile system. The method further comprises determining if a new communication link should be established with at least one of the communication resources based at least on the LOS analyses that were performed and establishing the new communication link if it is determined that the new communication link should be established. | 01-27-2011 |

| 20110288746 | CONTROL SYSTEM AND METHOD FOR IMPROVING COLD STARTABILITY OF SPARK IGNITION DIRECT INJECTION (SIDI) ENGINES - A control system includes an engine enable module and a fuel control module. The engine enable module determines whether predetermined operating conditions of a spark ignition direct injection (SIDI) engine are satisfied and enables an engine prime mode when the predetermined operating conditions are satisfied. The fuel control module controls a fuel injector to deliver a prime pulse to a cylinder of the SIDI engine when the engine prime mode is enabled. The fuel injector delivers the prime pulse by opening for a pulse width to inject fuel directly into the cylinder when the SIDI engine is stopped. | 11-24-2011 |

| 20090120278 | ELECTROHYDROSTATIC ACTUATOR INCLUDING A FOUR-PORT, DUAL DISPLACEMENT HYDRAULIC PUMP - An electrohydrostatic actuator including an unbalanced area actuator whereby movement of an actuator piston causes a greater change in displacement on a first side of the actuator piston having a first area than on a second side of the actuator piston having a second area. The actuator includes a four-port, dual displacement hydraulic pump having a first pair of ports and a second pair of ports. If an axial piston pump is used, the pistons may be arranged in first and second rings of pistons arranged concentrically about a central axis. The pump has a port plate with a first pair of ports associated with the first ring of pistons and a second pair of ports associated with the second ring of pistons. At least one of the first pair of ports and at least one of the second pair of ports are connected to the first side of the actuator piston. At least one of the first pair of ports is connected to the second side of the actuator piston. At least one of the second pair of ports is connected to a reservoir of hydraulic fluid. | 05-14-2009 |
| 20100239439 | ENGINE DRIVEN PUMP DISCONNECT MECHANISM - An engine driven pump includes a drive apparatus that is assisted into the disengaged condition prior to disconnect by the ported pressure in the pump. A spring-biased actuator assembly is fluidly connected to a depressure valve of the pump, and along with its spring bias, urges a yoke into a disengaged position to disengage the gear faces of the mechanism. A trigger link held by a solenoid plunger normally retains the yoke in an engaged position. A drive socket can be accessed to return the yoke, and hence the gear faces, into the engaged position. The pump can be disengaged under command during flight or when the aircraft is on the ground, and can only be re-engaged when the aircraft is on the ground. The drive apparatus has few rotating components to reduce rotational inertia; and is enclosed within a housing with no exposed components with all parts continually lubricated. | 09-23-2010 |
