Abstract: Functionalized catalysts for use in a hydrogen evolution reaction (HER) contain nanoparticles containing a transition metal enveloped in layers of graphene, which renders the nanoparticles resistant to passivation while maintaining an optimal ratio of transition metal and transition metal oxide in the nanoparticles. The catalysts can be utilized with anionic exchange polymer membranes for hydrogen production by alkaline water electrolysis.

Abstract: A method, system, and apparatus for multiplexing comprising feeding a signal into a sampler, splitting a first signal into an even branch at a first set of times, splitting a second signal into an odd branch at a second set of times, feeding a switch bleed current into the first branch at the second set of time and feeding the switch bleed current into the second branch at the first set of time.

Abstract: Register banks are used to allow for fast beam switching in a phased array system. Each beam forming channel is associated with a register bank containing M register sets for configuring such things as gain/amplitude and phase parameters of the beam forming channel. The register banks for all beam forming channels can be pre-programmed and then fast beam switching circuitry allows all beam forming channels across the array to be switched to use the same register set from its corresponding register bank at substantially the same time, thereby allowing the phased array system to be quickly switched between various beam patterns and orientations. Active power control circuitry may be used to control the amount of electrical power provided to or consumed by one or more individual beam forming channels such as to reduce DC power consumption of the array and/or to selectively change the effective directivity of the array.

Abstract: A rotary power tool comprises a drive mechanism including an electric motor and a transmission, a housing enclosing at least a portion of the drive mechanism, a spindle rotatable in response to receiving torque from the drive mechanism, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, a sleeve bushing supported by the housing, and a bearing rotatably supporting the spindle. The spindle has an outer race. And, the outer race of the bearing moves along the sleeve bushing during reciprocation of the spindle when the first ratchet and second ratchet are engaged.

The spindle is movable relative to the housing in response to contact with a workpiece, causing the first and second ratchets to engage and the spindle to reciprocate while rotating. The outer race of the bearing moves along the sleeve bushing during reciprocation of the spindle when the first ratchet and second ratchet are engaged.

Abstract: A scalable voucher system used to manage how content (specifically advertisements) is delivered to client devices is described. The advertisements are stored on a plurality of different ad servers. With the use of vouchers that are assigned to each ad server for pre-determined periods of time, the voucher system is able to manage when and how advertisements should be provided to the client devices. The voucher system also provides an arrangement that allows for the use of additional ad servers to be scalable. As the number of client devices that would need to be serviced with advertisements increases, the voucher system is able to easily accommodate the increase number of clients with the implementation of additional clusters of ad servers and corresponding processors without significant changes to the underlying system.

Abstract: A fingernail file case includes a hole through which filing can take place while the case remains otherwise fully closed. The case may optionally include a projection adapted to scrape under a fingernail and/or a blade adapted to push a cuticle.

Abstract: A private cloud-based processing pipeline apparatus and method for its use is disclosed. A first load balancer directs data packets to one of a plurality of collectors. The collectors authenticate the data packet. Then a second load balancer receives the data packet from the collector and to direct the data packet to one of a plurality of extract transform load (ETL) frontends, where the data packet is converted from a platform dependent form into a platform independent form and loaded into a queue. Handlers then process the converted data packets. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: A method, device and software for ensuring path diversity across a communications network are disclosed. The method forms a digest of resources used in an initial, working, path is created as the initial path is established. This digest may be used during the formation of a subsequent, protection, path. Each node along the subsequent path can use the digest to ensure that resources are not common to the initial and subsequent paths. Conveniently, the digest may take the form of a Bloom filter that summarizes local information about resources known to each node along the initial path. The method lends itself for use in an MPLS compliant network or any connection oriented network such as an ATM, SONET or switched optical network.
