Abstract: A blade change mechanism configured to attach a blade to a transmission rod of a power tool, the blade change mechanism including a support body, a blade retention structure, and a component. The blade retention structure is coupled to the support body and includes a blade retention component movable to hold the blade in a locked state in response to engagement of the blade with the blade change mechanism on insertion of the blade. The component is movable to vary the blade retention component to hold the blade in the locked state. The component is further movable to vary the blade retention component to an unlocked state in which the blade retention structure is disengaged from the blade. The blade retention structure is held in the unlocked state absent the blade being fully inserted into the blade change mechanism.

Abstract: Ion-conductive membranes composed of glassy organic frameworks are provided. Also provided are devices incorporating the ion-conductive membranes and methods of making the ion-conductive membranes. The glassy organic framework membranes can be synthesized from nitrile- and/or acetyl-group containing monomers using thermally controlled, step-wise nitrile and/or acetyl trimerization reactions and film casting techniques.

Abstract: Amphiphilic complexing agents for use in electrolyte solutions are provided. The complexing agents include at least one soft ionic group covalently bonded to at least one hard ionic group or polyether chain. The soft ionic group couples with soft, oppositely charged ionic redox species in an electrolyte solution, and the hard ionic groups or polyethylene chains render the complexes formed by the complexing agents and ionic redox species soluble in the electrolyte solution. The size of the complex formed by the coupling of the amphiphilic complexing agent to the soft ionic redox species is substantially larger than the size of the soft ionic redox species alone and, as a result, electrochemical cells that include the amphiphilic complexing agents in an electrolyte solution have less membrane crossover than analogous electrochemical cells that do not include the amphiphilic complexing agents.

Abstract: Disclosed herein is an automated cross-dock management system configured to optimize moves on a cross-dock. The automated cross-dock management system uses inbound manifest data to calculate ordered move instructions for all inbound movable platforms, inbound modular decks, and inbound freight. The ordered move instructions can be assigned to be carried out by manual conveyance vehicles or by automated guided vehicles based upon a plurality of criteria. The automated cross-dock management system is also able to detect damaged freight on the cross-dock using a combination of streams from video cameras.

Abstract: A facility providing systems and methods for managing and optimizing energy consumption and/or production is provided. The facility provides techniques for optimizing energy-consuming and energy-producing systems to meet specified demands or goals in accordance with various constraints. The facility relies on models to generate an optimization for an energy system. In order to use generic models to simulate and optimize energy consumption for an energy system, the generic models are calibrated to properly represent or approximate conditions of the energy system during the optimization period. After the appropriate models have been calibrated for a given situation using one or more modeling parameter sets, the facility can simulate inputs and responses for the corresponding system. The facility uses the generated simulations to generate a plan or control schedule to be implemented by the energy system during the optimization period.
