Abstract: A zero-gravity hoist system including a chain fall, a motor coupled to the chain fall and configured to drive the chain fall in one or more directions, a power supply configured to provide power to the motor, and a controller having one or more electronic processors. The one or more electronic processors are configured to measure a first force of a load in response to receiving an input, store the measured first force in a memory of the controller, measure a second force of the load, determine a difference between the second measured force and the first measured force, and adjust a height of the load based on determining that the second force differs from the first force by a predetermined threshold.

Abstract: A system and method for defining specifications for outputting content to multiple formats. More specifically, a system and method for creating a single multi-purpose stylesheet file from a single user interface, the single multi-purpose stylesheet being capable of designing multiple output media formats. For example, the multi-purpose stylesheet may convert input XML content to HTML, PDF, PostScript, WML, or other output formats. The method may include creating or modifying a multipurpose stylesheet containing formatting rules corresponding to various properties of different output media formats. A user can configure the multi-purpose stylesheet by selecting different formatting properties for different output media formats.
