Abstract: The present disclosure generally relates to a lock including a blocker (e.g., a bolt) useable to selectively prevent access through a portal such as a door. The blocker can be retained in a blocking position to prevent access through the portal by a retainer. In alternative embodiments, the blocker can also be retained in an open position to allow access through the portal. A retainer can be utilized to retain the blocker in the blocking position preventing access through the portal and can also be utilized, in certain embodiments, to retain the blocker in the open position to allow access through the portal. A retainer blocker can be utilized to maintain the retainer in position to retain the blocker (e.g., bolt) in a fixed position. An actuator may, in certain alternative embodiments, be employed to position the retainer blocker. In certain embodiments, the actuator is controlled by an electronic controller.

Abstract: These teachings provide for quickly yet accurately forming an influence matrix by generating the influence matrix via integration with a Monte Carlo particle transport simulation. The resultant influence matrix can then be utilized in an ordinary manner when optimizing a radiation treatment plan. By one approach, the foregoing comprises generating the influence matrix via integration with a Monte Carlo particle transport simulation on a particle-by-particle basis. For example, for each particle, these teachings can provide for identifying a spot to which the particle belongs and then adding a dose deposited by the particle during transport to an influence matrix element that corresponds to a spot to which the particle belongs and a voxel to where the dose was deposited.

Abstract: Systems and methods for online assisted pre-intervention or “prevention” are described. A prevention system may provide the ability to initiate a prevention campaign in order to create a customized support forum for persons who may be afflicted by a harmful addiction. The prevention system can receive a request to initiate a campaign for a recipient from a host and facilitate the invitation of other participants to the campaign. Knowledge-based questionnaires may be dynamically generated for the host and participants, and a profile built for the recipient based on received responses. Customized messages may be generated by the prevention system using expert knowledge-based rules, and delivered to the recipient. The messages may be unique to the recipient based on the recipient's circumstances and relationship to the host and participants. Support services provided by the prevention system encourage the recipient to agree to accept help and provide action plan recommendations.

Abstract: Techniques and tools are described for rendering views of a map in which map metadata elements are layered in 3D space through which a viewer navigates. Layering of metadata elements such as text labels in 3D space facilitates parallax and smooth motion effects for zoom-in, zoom-out and scrolling operations during map navigation. A computing device can determine a viewer position that is associated with a view altitude in 3D space, then render for display a map view based upon the viewer position and metadata elements layered at different metadata altitudes in 3D space. For example, the computing device places text labels in 3D space above features associated with the respective labels, at the metadata altitudes indicated for the respective labels. The computing device creates a map view from points of the placed labels and points of a surface layer of the map that are visible from the viewer position.
