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 pressure control device for isolating a section of a conduit comprises a support member, a flexible cup member mounted to the support member, a first swellable element, the first swellable element adapted, upon activation by an activation fluid, to urge a first portion of the cup member outwards into engagement with a conduit surface and at least one bypass arranged to permit the activation fluid to bypass the swellable element and build up behind a second portion of the cup member.

Abstract: A sealing apparatus for sealing a well bore is described. The sealing apparatus comprises a sealing element adapted to be moved from a run-in configuration to a set configuration, a first back-up layer and at least one second back-up layer sandwiched between the sealing element and the first back-up layer. The at least one second back-up layer comprises a thinner material than the first back-up layer. The first back-up layer and the at least one second back-up layer are adapted to be moved from the run-in configuration to the set configuration under the action of the sealing element.

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 sealing element for a packer is described. The sealing element comprises an annular body having an internal surface defining a throughbore, the internal surface adapted to engage a mandrel having a mandrel diameter. The annular body internal surface defines first and second regions, the throughbore diameter of the regions being less than the mandrel diameter.

Abstract: A container (12) suitable for use in packaging pharmaceutical products such as tablets and capsules. The container (12) can be withdrawn from a box or sleeve (14) in a first direction X to a fully extended position whereby a user can remove any item stored by the container (12). The container (12) has a base (32) which includes an end portion (40) that remains substantially within the box or sleeve (14) when in the fully extended position. The base (32) carries at least one chamber formation (42) for containing an item to be removed by the user. The base (32) also has at least one stabilizing formation (44) on the end portion (40) that interacts with the box or sleeve (14) when in the fully extended position to resist pivoting of the container (12) relative to the box or sleeve (14). The or each stabilizing formation (44) differs in size and/or shape to the or each chamber formation (42), and has a length in the first direction X that is greater than or equal to its width in a second direction Y.

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.
