The system may further include a processor unit for receiving one or more signals from the at least one magnetic-field sensor and for determining the location and/or one or more dimensions of the line-attached tool while approaching, moving through or moving away from the body.

Abstract: A communication system including a registry, a traffic service-level classifier, and a network traffic controller receives messages from a communication address, and performs a proactive address verification process to determine a class of service for the network traffic controller to utilize for the communication address, thereby unlocking additional functionality for the communication address on the network.

Abstract: A fluid exchanger may exchange a fluid (e.g., coolant) in a reservoir (e.g., vehicle radiator) by removing or withdrawing a first fluid (e.g., old, spent, used, etc.) and by introducing a second fluid (e.g., new, clean, etc.). For example, the fluid exchanger may use a negative pressure, suction, or vacuum to draw the first fluid from the reservoir, and subsequently, the second fluid may be transferred into the reservoir using a negative pressure held in the reservoir, a positive pressure applied to the second fluid, or a combination thereof. The fluid exchanger may also include a multi-purpose, hand-held nozzle that can change an operation of the fluid exchanger from a withdrawing mode to a dispensing mode.

Abstract: The present disclosure relates to an adapter that is attachable to an engine vacuum source (e.g., insertable into an end of a vehicle-engine vacuum hose) to receive a cleaning fluid from a canister (e.g., aerosol can) and to meter the cleaning fluid into the vacuum source. The adapter may include a vacuum-source insert and a nozzle receiver. In addition, the adapter may include a fluid path between the vacuum-source insert and the nozzle receiver that meters a flow of cleaning fluid.

Abstract: An apparatus, a system and a process may be used for regulating a wellhead control mechanism. The apparatus may control actuation of the wellhead control mechanism by moving a moveable body of the apparatus between a first position and a second position. When the apparatus is in the first position, a valve actuator is actuatable. When the apparatus is in the second position the valve actuator is physically interfered from actuating. Additionally, when the apparatus is in the second position, the wellhead control mechanism cannot be actuated and is held in either an open, a partially open or a closed position. Further, a system may directly control an actuation of a wellhead actuation mechanism.

Abstract: A host controller for a distributed wireless local area network (WLAN) includes: a communications interface connected to each of a set of wireless access points (APs); a memory storing (i) identifiers of each of the wireless access points, and (ii) a master identifier of the host controller; and a processor configured to: receive a notification, from a first one of the APs, that the first AP has completed an association with a client device; in response to receiving the notification: deploy association data, including an identifier of the client device, to each of the APs; initiate a handshake mechanism with the client device, via a selected one of the APs, to generate an encryption key; and provide the encryption key to each or the APs to enable data exchange between the client device and each of the APs.

Abstract: The present invention relates to a tamper-proof container comprising a container, a cap, and a tamper evidence mechanism, including a female component, a male component, and a locking member. The container to hold contents includes a top portion, a bottom portion, and a wall portion with a cap attached to the top portion of the container. The cap includes an inner portion with orifice and a lid pivotally connected to the inner portion via a hinge for opening and closing the tamper-proof container. The cap further includes a sloped portion at its front region which has a smooth surface for applying the contents directly to the desired area. After contents is filled in the container, the lid is closed for the first time, and the tamper evidence mechanism is secured by locking the male component in the corresponding female component with the locking member provided over the male component.

Abstract: A database service that receives and manages data into columnar databases. Individual columnar databases or columnar database partitions are associated with a dictionary that provides an encoding for the data in the columnar database. The database service generates count information for the dictionary entries. The database service also maintains one or more augmented dictionary values that correspond to featurization criteria. The database service applies the augmented dictionary values to respond to requests for feature data.

Abstract: A computing system for recovery of lost access points in a distributed wireless local area network, including: (a) a host controller, (b) a plurality of access point, and (c) a plurality of stations. When setting up the network, the host controller is configured to register the plurality of access points, instruct the access points to send beacons to the plurality of stations, and perform a handshake to generate a unique encryption key for each of the plurality of stations. When the host controller detects that a physical access point has been lost and then recovered, it can optionally perform a handshake to generate a new encryption key and transmit this new encryption key to the other access points in the network before data communication commences to any of the stations through the recovered physical access point.
