Abstract: An office-type chair includes a weight responsive mechanism having a front link pivotally connected between the base and the seat, a rear link pivotally connected between the seat and the backrest, and a resilient element, wherein the force of a user occupying the seat pivots the front link and the rear link against a resistance created by the resilient element an amount proportional to the weight of the user to increase the effective length of the moment arm between the user and the recline axis, such that the force to pivot the backrest about the recline axis varies as a function of the weight of the user. In one embodiment, a secondary recline spring between the base and the backrest, the secondary spring contributing to the biasing force of the recline tension spring when the backrest is moved to the reclined position.

Abstract: A filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a filter key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter housing assembly may be attached to, and removed from, a filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

Abstract: Crowd funding for innovation includes distributing a proposal with a description of a project idea, an amount of funds requested, and a time frame for raising the funds. Ownership of the project is transferred to an entity, which receives contributions from contributors and for each of the received contributions converts the contribution to a corresponding amount of virtual coin and adds the contribution to the funds. If the funding goal is complete within the time frame, the entity converts the coins to actual money and releases the money to the requestor. After completion of the project, the entity determines if the project is successful and can commercialize successful projects. For certain successful projects, the entity can also distribute funds to the contributors.

Abstract: A castable, moldable, and/or extrudable structure using a metallic primary alloy. One or more additives are added to the metallic primary alloy so that in situ galvanically-active reinforcement particles are formed in the melt or on cooling from the melt. The composite contains an optimal composition and morphology to achieve a specific galvanic corrosion rate in the entire composite. The in situ formed galvanically-active particles can be used to enhance mechanical properties of the composite, such as ductility and/or tensile strength. The final casting can also be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final composite over the as-cast material.

Abstract: An asynchronous medium access control layer scheduler increases efficiency for directional mesh networks by removing extra overhead in the time slots. The efficiency is increased by dividing time slots into sub-slots to allow for a receiving node to be offset by at least one sub-slot from the transmitting node. This enables the scheduler to more efficiently schedule operations for the nodes so that nodes can be performing other functions rather than waiting to receive a transmission or waiting after transmitting a transmission. The sub-slots may be sized to approximate the transmission propagation time or time of flight delay.
