Abstract: A digital avatar may be used to represent, track, and/or monitor behavior of a tool (e.g., a downhole tool) to track particular tools based on specific characteristics of the tool. For instance, a thermal digital avatar may be used to track or predict thermal generation for particular job durations or power levels based on physical characteristics of the tool. For example, the thermal digital avatar may be used to predict thermal generation based at least in part on a thermal efficiency that is based at least in part on the age of the tool, changes or imperfections in heatsinks, results of after-manufacture thermal testing, or a combination thereof.

Abstract: A system for overhead anchor evacuation according to embodiments of the present invention includes a support bar configured to extend overhead of a user, a device mount in sliding engagement with the support bar, the device mount slideable along the support bar between a first position in which the device mount is on an inside of an edge of a building, and a second position in which the device mount is on an outside of the edge of the building, wherein the device mount slides freely between the first and second positions during the user's normal use of the system, and a controlled descent device coupled to the device mount.

Abstract: A rope thimble with a closed curve substantially reduces rope wear. Various closed curve rope thimbles may include side walls of different heights.

Abstract: A carry and deploy bag system according to embodiments of the present invention includes a holster for housing a controlled descent device and an anchor; a rope pouch for receiving a rope that is securable to the controlled descent device and the anchor; and a connecting gooseneck extending between the holster and the lumbar pouch that protects the rope as it runs through the connecting gooseneck from the lumbar pouch to the holster; wherein the holster comprises a tear-away cover flap that can be opened and disconnected from the holster in one motion.

Abstract: An edge protector for placement between an edge and a rope according to embodiments of the present invention includes an inner surface having a rope guide, the rope guide including a first guide rail, a second guide rail, and a rope travel path between the first and second guide rails along which the rope slides in a rope travel direction, and an outer surface comprising one or more edge engagement bands, the one or more edge engagement bands oriented substantially perpendicularly to the rope travel direction and configured to engage the edge to deter slippage of the edge protector with respect to the edge.

Abstract: A logging-while-drilling (LWD) tool includes a bottomhole assembly (BHA); an electronic device carried on the BHA; and a bunched wire contact providing an electrical connection between the electronic device and a electrical power source at the BHA. The bunched wire contact includes a plurality of wires each of which has sufficient capacity to provide the requisite electrical current for operation of the electronic device.

Abstract: A baby changing, cleansing and bathing station with a basin hinged at the rear to pivot away from the wall overtop an existing toilet, a shower wand with adapter for connection to an existing faucet or shower, a front leg assembly for automatically deploying upon pivoting down of the basin, and a fold-down drain for automatically deploying upon pivoting down of the basin to drain water from the basin into said toilet. The automatic legs and drain allow for easy one-hand deployment while carrying a baby. The baby changing, cleansing and bathing station is adaptable to a freestanding configuration with either a cabinet enclosure or rear leg assembly for freestanding support, or a wall-mounted configuration with or without a cabinet enclosure.

Abstract: A cellulosic particle, especially useful as a cat litter, is manufactured by agglomerating a fibrous cellulosic feed material in the presence of water, compacting the surface of the agglomerated particles, and drying the particles.

Abstract: A closed paperboard carton for containing hot foods includes an automatically openable vent responsive to presence of hot vapor emanating from the food to accommodate escape of the vapor. The vent comprises a tab portion formed in a wall of the carton, defined by at least a pair of equal-length knife cuts and having a region of connection with the wall. Vapors emanating from the hot food condense, and are absorbed by the inwardly facing wall surfaces of the paperboard carton. Absorption of condensed vapors in the region of the tab causes the inwardly facing surface of the tab to swell so that it curls outwardly and forms a vent. Once the vapor has substantially escaped, the inwardly facing wall surfaces tend to dry out, accompanied by uncurling of the tab to its original, vent-closing position.
