Abstract: Simulated bog-down system and method for power tools. One power tool according to an example embodiment includes a power source and a motor selectively coupled to the power source. The motor includes a rotor and stator windings. The power tool includes an actuator configured to generate a drive request signal and a power switching network configured to selectively couple the power source to the stator windings of the motor. The power tool includes an electronic processor coupled to the power source, the actuator, and the power switching network. The electronic processor is configured to detect a load on the power tool and compare the load to a threshold. The electronic processor is configured to determine that the load is greater than the threshold, and to control the power switching network to simulate bog-down in response to determining that the load is greater than the threshold.

Abstract: A lead-free KNN-based piezoelectric material represented by the composition formula (KaNabLic)(NbdTaeSbf)Og, where 0.4?a?0.5, 0.5?b?0.6, 0.01?c?0.1, 0.5?d?1.0, 0.05?e?0.15, 0.01?f?0.09, 1?g?3. In one embodiment, the lead-free KNN-based piezoelectric material has a d33>300 pm/V and a Tcurie>250° C. In one embodiment, the d33 and Tcurie of the lead-free textured KNN-based piezoelectric material can be adjusted by creating phase boundaries of (i) orthorhombic to tetragonal (O-T), (ii) rhombohedral to orthorhombic (R-O), and (iii) orthorhombic to tetragonal (O-T). In one embodiment, the lead-free KNN-based piezoelectric material is textured with NaNbO3 or Ba2NaNb5O15 seeds which are platelet or acicular shaped. In one embodiment, the amount, orientation, or particle size distribution of the NaNbO3 or Ba2NaNb5O15 texturing seeds in the lead-free textured KNN-based piezoelectric material can be altered.

Abstract: The present invention concerns a method for allocating at least one resource to a plurality of resource consumers in a cloud computing environment. The method comprises the steps of defining a maximum resource consumption for each of the plurality of resource consumers; measuring a current resource consumption of each of the plurality of resource consumers; calculating based on the maximum resource consumptions and the current resource consumptions an unutilized amount of the at least one resource; and allocating at least a portion of the unutilized amount of the at least one resource to the plurality of resource consumers.
