Abstract: A wireless hoist system including a first hoist device having a first motor and a first wireless transceiver and a second hoist device having a second motor and a second wireless transceiver. The wireless hoist system includes a controller in wireless communication with the first wireless transceiver and the second wireless. The controller is configured to receive a user input and determine a first operation parameter and a second operation parameter based on the user input. The controller is also configured to provide, wirelessly, a first control signal indicative of the first operation parameter to the first hoist device and provide, wirelessly, a second control signal indicative of the second operation parameter to the second hoist device. The first hoist device operates based on the first control signal and the second hoist device operates based on the second control signal.

Abstract: Disclosed embodiments relate to the graphical display of relationships between entities of interest, and specifically between entities in a network of relationships. In such embodiments, multiple icons on an axis between two entities are used to indicate that the entities have multiple relationships. Disclosed embodiments also provide methods of navigating, filtering, and manipulating the display of networked relationships, according to the numerical distribution of relationships and specific combinations of relationships. Disclosed embodiments provide methods of manipulating the display of networked relationships so that relationships between entities can be visually collapsed, and entities can be treated as links between other entities for the purposes of filtering and display.
