Abstract: A single-piece mechanical advantage device comprising a solid body formed by machining, molding, or casting, with one or more integrally formed passive pulley grooves configured to redirect cordage without rotating components. The device includes through-holes and anchor points for secure attachment to trees, poles, vehicles, or equipment using bolts, carabiners, or lashing. Multiple units may be stacked and lashed together to create compound pulley systems, with optional alignment features or variable groove diameters to reduce friction and cord interference. The body may incorporate drainage channels, surface texture for heat dissipation, and etched or laser-marked instructions for field use. Designed for durability and tool-free deployment, the device supports integration with belts, MOLLE-compatible gear, and other modular equipment systems. Variants may be color-coded and produced in multiple sizes to accommodate a range of load and environmental conditions.

Abstract: A skincare device having energy regenerating end effector is presented. In one embodiment, an end effector includes an inner end effector structure configured to oscillate about an axis. The inner end effector structure includes at least one magnet and a plurality of contacting elements configured to contact skin of a user. The end effector also includes an outer end effector structure having at least one induction coil. The at least one magnet and the at least one induction coil cooperate to generate electrical current in the at least one induction coil when the end effector oscillates about the axis.

Abstract: A skincare device having energy regenerating end effector is presented. In one embodiment, an end effector includes an inner end effector structure configured to oscillate about a first axis. The inner end effector structure includes at least one magnet and a plurality of contacting elements configured to contact skin of a user. The end effector also includes an outer end effector structure comprising at least one induction coil. The at least one magnet and the at least one induction coil cooperate to generate electrical current in the at least one induction coil when the end effector structure oscillates about an axis.

Abstract: The present invention relates to a selective estrogen receptor modulators of formula I (I); or a pharmaceutical acid addition salt thereof; and of formula II (II); or a pharmaceutical salt thereof; useful, e.g., for treating endometriosis and/or uterine leiomyoma/leiomyomata.

Abstract: A dry analytical element is disclosed which can be used to sensitively and rapidly detect and quantitate protein. The assays are carried out using a dye that reacts with protein and molybdate ion to produce a measurable change in the spectral absorption of the dye. Also disclosed are polymers which stabilize and enhance the accuracy of the assay, and compounds which reduce interference by bicarbonate.
