Abstract: Content is organized for brands by selecting a plurality of brand templates. After each selection, a set of properties is generated by applying a portion of settings of the respective brand template, with the remaining settings being overridden with settings for a channel communicating one of a plurality of presentations to a node of a network involved in the communication. The plurality of presentations may include different renditions of the same content. The properties may include sections configured for different focus areas and/or types of content associated with at tags to enable brand-level-targeting. Filters may be identified in the properties. Based on each of the identifications, a property from among the generated sets of properties may be selected based on comparisons with the associated tags.

Abstract: Surgical systems and methods for use with a hand-guided tool. The surgical system includes a robotic manipulator that holds a tool guide. The tool guide receives and guides the surgical tool to enable the tool to manipulate a bone. The robotic manipulator autonomously aligns the tool guide to a target orientation relative to the bone. The tool guide is moved to an initial location adjacent to the bone while remaining aligned with the target orientation. The initial location is suitable for the tool to perform an initial manipulation of the bone. The robotic manipulator facilitates withdrawal of the tool guide away from the initial location to a spaced location after the initial manipulation of the bone while maintaining alignment of the tool guide with the target orientation at the spaced guide location. The spaced guide location is suitable for the tool to perform a further manipulation of the bone.
