Abstract: In some embodiments, data from multiple vehicle-based natural gas leak detection survey runs are used by computer-implemented machine learning systems to generate a list of natural gas leaks ranked by hazard level. A risk model embodies training data having known hazard levels, and is used to classify newly-discovered leaks. Hazard levels may be expressed by continuous variables, and/or probabilities that a given leak fits within a predefined category of hazard (e.g. Grades 1-3). Each leak is represented by a cluster of leak indications (peaks) originating from a common leak source. Hazard-predictive features may include maximum, minimum, mean, and/or median CH4/amplitude of aggregated leak indications; estimated leak flow rate, determined from an average of leak indications in a cluster; likelihood of leak being natural gas based on other indicator data (e.g. ethane concentration); probability the leak was detected on a given pass; and estimated distance to leak source.

Abstract: A container can end includes a concave dome shape and may forgo a peripheral reinforcing bead around the center panel. The tab may also be curved. Tooling for forming the end and a corresponding method are provided.

Abstract: Methods and systems for providing alternate wireless and network service on a cruise ship or in other remote or isolated “captive” environments where available wireless communication options tend to be limited and/or bandwidth constrained. Aspects of the disclosed systems and methods allow existing wireless customers to continue using their normal wireless phone and phone number in the captive environments while still easily avoiding large roaming and bandwidth charges, all while nearly transparently maintaining the full range of normal wireless voice, text, and MMS services.

Abstract: A game controller for use with handheld game devices, for example smartphones, includes a cradle for holding the smartphone. The cradle is pivotable between an open position, extending from a base of the game controller, and a closed position in which the cradle is about a bottom wall of the base.

Abstract: A system for remotely monitoring and/or controlling a pool or spa. The remote control can utilize a microprocessor-based data acquisition and processing system, along with a network interface, to provide remote access to the pool or spa parameters, including but not limited to: temperature, pH, and ORP levels; and the status and control of pumps, heaters, ozone apparatus, and filters. The information is presentable via the Internet, a private or other networks, and can be accessed through known browsers or other convenient interfaces, allowing for operation across all computing platforms.

Abstract: The accessory drive unit, mounted intermediate an engine and a transmission, provides mounts for a water pump, an alternator, a supercharger and a starter. The accessory drive unit includes a main planetary gear driving a supplemental gear which is rotatably interconnected to a bevel gear driving a supercharger shaft. A first pilot gear is rotatably coupled to the main gear and is coaxially mounted to a second pilot gear. A water pump gear is rotatably coupled to the second pilot gear. An alternator gear is rotatably coupled to the first pilot gear. A flywheel is mounted on the engine drive shaft and has a peripheral gear thereon. The starter has a geared drive shaft which is adapted to rotatably interlink with the peripheral gear on the flywheel.

Abstract: A gas turbine engine (10) includes a first fire zone (Zone 3) in the region of a core of the engine and a second fire zone (Zone 1) in the region of a fan case of the engine, the first and second fire zones being separated by fire walls. The first fire zone is located generally radially inwardly of the second fire zone but includes a bifurcation part which extends radially outwardly of the remainder of the zone for limited circumferential extent. The engine further includes a disconnect panel (52) mounted on the fan case (32) to extend radially outwardly therefrom, the disconnect panel (52) forming a fire wall and providing means for pipes and harnesses (44) to be routed therethrough.

Abstract: The integrated bell housing on an engine, carries a supercharger, an alternator, a water pump and a starter. The engine has a crankshaft which is coupled to a flywheel in the casing as is a geared transmission. The flywheel has a first gear and a second gear. The first gear drives a supercharger drive shaft which drives the supercharger. The second gear is coupled to an alternator drive shaft such that the flywheel drives the alternator. A water pump drive shaft is keyed to the crankshaft and is rotatably mounted through the bell housing.

Abstract: Apparatus and methods include a first data communication link (hardwired or wireless) between a sensor and an Internet communication interface or device (such as a Java™-enabled or other programmable cellular telephone). The cellular telephone can provide an always-on link to a network such as the Internet, on which websites and related hardware and software tools can permit ready and virtually unlimited access to and interaction with the original data and sensor, and/or the sensor's system. In the preferred embodiment, a Java™-enabled cellular telephone interfaces directly with one or more sensors as well as with a network such as the Internet, to provide a data acquisition and control channel. The cellular telephone's display and keypad can provide a local display and data entry for the sensor and/or the sensor's system.

Abstract: A remotely operated vehicle-mounted pump is used to pump water from a suction pile, causing the suction pile to sink into the seabed of the ocean. The remotely operated vehicle exhibits a first mating member, and the pile exhibits a second mating member. The mating members define a channeled interface, channeling the first and second mating members to a common axis.
