Abstract: Systems and methods for reducing inrush current into a component, such as a power converter (e.g., LED driver), which receives alternating current (AC) power from an AC power source (e.g., AC mains). The method may include pre-charging the input capacitance of a component or circuit for a determined period of time after closing of a control switch (e.g., photocontrol, contactor) using a capacitive load pre-charge circuit (e.g., resistor), and then shorting the capacitive load pre-charge circuit using a bidirectional AC switch coupled in parallel with the capacitive load pre-charge circuit after the determined period of time to selectively bypass the capacitive load pre-charge circuit. The bidirectional AC switch may include two source-connected metal oxide semiconductor field-effect transistors (MOSFETs) which have a very low “on resistance,” such that during steady-state operation, the protection circuit wastes very little power compared to conventional inrush protection circuits.

Abstract: A very small aperture terminal (VSAT) installation tool is provided having the ability to measure cable loss along an interfacility link (IFL) between an outdoor unit and an indoor unit of the VSAT. Radio frequency (RF) signals can be transmitted from the indoor unit to the outdoor unit, where the RF signals are intercepted along the IFL prior to reaching the outdoor unit, and the output power is determined. The determined output power is compared to an expected output power at the indoor unit. The delta between the determined output power and the expected output power can be used to adjust the power of the indoor unit such that the outdoor unit can operate without reaching its compression point. The determined output power can be extrapolated based upon measured of the output power performed over a range of frequencies at which the indoor unit operates.

Abstract: This invention is embodied in a power/data interface for connecting two modules at the leading edge (i.e., the “tip of the spear”) of a fire suppression operation. The power/data interface serves as an operational link between a housing device (for protecting a battery and other electronic equipment) and an accessory like a thermal imaging camera (“tic” camera), video camera or other sensory perceiving device. The power/data interface not only provides power to an accessory by connecting it to a power source, but the power/data interface can exchange data between the accessory and the housing device. Such exchange of data enables electronics stored within the housing device to record and protect data captured by accessory on a flash drive or other recordable media. In addition to providing power and exchanging data with an accessory, the power/data interface can also accept battery pack that can be used to recharge a battery or other power source located inside the housing device.

Abstract: A system and method for the on-site separating and treating of a hydrocarbon liquid stream at an oil and gas production site is disclosed. The system comprises an oil and condensate distillation unit and a vapor recovery unit. In one embodiment, the oil and condensate distillation unit operates at low pressure or vacuum conditions to reduce the vapor pressure above the column of oil within the tubing, thereby increasing the production of oil and condensate and capturing entrained natural gas otherwise lost or burned off. The system further functions to improve the quality and volume of recovered natural gas and to decrease air pollution, in addition to increasing oil and condensate production at the well site.

Abstract: When calculating true inter-camera distance, offset images of a reference object such as a lane marker from at least two cameras coupled to an articulating vehicle are overlaid and shifted until the reference objects in each image are aligned. The distance by which the reference object images are shifted, as well as any rotation required to align the images, is used to calculate the actual distance between the cameras and to compensate for average yaw angle between the cameras when positioning the images for digital stitching to generate a composite “surround view” image.

Abstract: The present invention describes a fuel-management system for minimizing particulate emissions in turbocharged direct injection gasoline engines. The system optimizes the use of port fuel injection (PFI) in combination with direct injection (DI), particularly in cold start and other transient conditions. In the present invention, the use of these control systems together with other control systems for increasing the effectiveness of port fuel injector use and for reducing particulate emissions from turbocharged direct injection engines is described. Particular attention is given to reducing particulate emissions that occur during cold start and transient conditions since a substantial fraction of the particulate emissions during a drive cycle occur at these times. Further optimization of the fuel management system for these conditions is important for reducing drive cycle emissions.
Abstract: The SACK scoreboard is used in slow recovery and the SACK scoreboard and an application programmed timeout are used to determine the initial CWND in slow recovery. The CWND is calculated so that all packets will be recovered before the application times out. A new socket option is provided for an application to program an application timeout (say APP_TO). This value is used in conjunction with the RTT (round trip time) to determine the initial CWND value to insure completion before timeout. Along with the timeout, the application can also set the mode as “soft,” where the CWND value is set to “1” as conventional but when that packet is ACKed, the CWND value is increased immediately to a modified calculated value to allow timely recovery.
