Additional friction-retained and fixed attachment configurations of the dental anchor device are provided, along with methods of securing a dental appliance in a subject's mouth by means of the friction-retained and fixed attachment dental anchor devices.

Abstract: A sealing assembly for installation on a port of a spring brake actuator includes a plug, a one-way valve and a cap. The plug receives the one-way valve for providing one-way air flow through the orifices and maintaining about two psi in the spring brake chamber at zero stroke. An elastomeric piece is affixed to a first set of segments of the plug for sealing against an inner surface of the port. The cap has arms sized to extend around a third set of segments of the plug and snap onto the plug. A fourth set of segments of the plug elastically deform so the sealing assembly can be installed and removed from the port easily.

Abstract: In some embodiments, apparatuses and methods are provided herein useful to automatically balance and buffer the return of empty containers or other totes to a plurality of areas. In some embodiments, a control circuit employs a logic system in which empty totes are directed along primary, secondary, or tertiary paths depending on information gathered from sensors regarding the availability of space for empty totes at a plurality of potential destinations. In this way, the return of empty totes to one or more points of origin may be buffered to balance the number of empty totes in one or more areas.

Abstract: In a computing system, data is ingested into a primary row of shards in a stamp data structure. The stamp data structure includes a primary row of data shards and a set of replica rows of data shards so the data shards are arranged in rows and columns in the stamp structure. The ingested data is replicated from the primary row into the replica rows of data shards. Each of the data shards, in each row, is evaluated to identify a particular data shard in each column of shards to generate a logical row of data shards. Queries against the data shards are serviced from the logical row of data shards. The system dynamically controls expansion and contraction of the number of data shards in a row and of the number of replica rows.

Abstract: A motion-based push activation power assist system for manual wheelchairs. The system uses motion-based measurements to determine when the user applies a push to the wheelchair handrims and brakes with the handrims. The push recognition activates a drive system that provides an assistive driving force-pulse to the wheelchair to reduce the demand on the user during propulsion. The brake recognition deactivates the power assist. The provided power assist is proportional to the sensed push and can be modulated to different proportional settings.
