Abstract: Medium, method and system for a distributed ledger system for recording asset provenance and titling information. The distributed ledger may store information that can be used to tie a particular digital asset provenance tag to an associated asset such as a serial number or other identifying indicia. The digital asset provenance tag may further store information regarding the provenance of the asset in question, including the history of the production and previous ownership of the asset. Thus, a prospective purchaser of the asset can confirm that the asset is what it is purported to be and that the seller is actually the owner of the asset prior to purchase.

Abstract: A docking station for a mobile cleaning robot can include a base, a housing, and a pad cleaning system. The base can be configured to receive the mobile cleaning robot. The housing can be connected to the base. The pad cleaning system can be connected to the housing and can include a reservoir configured to retain liquid therein. The pad cleaning system can also include an agitator located at least partially within the reservoir. The agitator can be engageable with a cleaning pad of the mobile cleaning robot.

Abstract: A method and apparatus is shown for measuring diameter of sucker rods during reworking of an oil well. Diameters are compared to known data tables to determine if a sucker rod should be replaced. If undue wear has occurred to the guides, the sucker rod will be replaced. If wear is excessive, additions guides will be added to the replacement sucker rod.

Abstract: A headphone that includes a headband and one or two earcups. The earcups are movably coupled to the headband by a joint that is constructed and arranged to allow translation of the earcup relative to the headband along a translational axis, and rotation of the earcup from a neutral position in both directions about the translational axis, where in a first direction the rotation extends for at least about 90 degrees from the neutral position. The joint is further constructed and arranged to accommodate an electrical cable.

Abstract: A wireless headset with a headband that is constructed and arranged to fit over a user's head. The headband includes an antenna that is adapted to transmit and receive wireless signals, and electronic signal processing hardware that is electrically matched to the antenna. The headset also includes earcups carried by the headband, each earcup arranged to sit on, over or near one ear of the user. Each earcup has an audio transducer.

Abstract: Two lighting devices for producing flames, and two fuel compartments for holding combustible liquid fuel such as butane comprises a double sided lighter. Each end of the lighter provides a lighting device, and each lighting device is connected to a fuel compartment. The fuel compartment supplies combustible fuel to the lighting device, which converts the fuel into a flame. The fuel compartments may be disposable or refillable.

Abstract: Horizontal electrophoresis is performed in a cell that includes a tank and a pair of electrodes, each mounted on an electrode support that is easily inserted into and removed from the tank, and once inserted, is secured in position by one or more spring-loaded, manual-release locking features.

Abstract: A fishing rod support rack has upper and lower wire frames. The lower frame has a continuous wire hoop, a wire shelf assembly, and a plurality of bent wire loops all welded together. The upper frame has a continuous wire hoop and a plurality of bent wire loops welded together. The upper and lower frames are attached to a wall in such a selectively spaced vertical relation that the loops of the upper frame generally align directly above the loops of the lower frame. The shelf assembly has upper surface portions on which the butt ends of the fishing rods can be removably supported. The loops of the lower frame removably receive the butt ends of the fishing rods therethrough and afterwards engage the grips of the removably supported fishing rods, thereby providing clearance among the removably supported fishing rods.
