Abstract: A method and system for managing hierarchical content having a plurality of messages where a navigation widget with message zones receives messages from a message database. When a message zone is selected, a message list is updated to show only those messages specific to that message zone. When a message from the message list is selected, the message zone renders a preview of the selected message within the message zone.

Abstract: A machine implemented method and system for managing variation and customization of content or touchpoints for customer communications management. The touchpoint has a plurality of message zones able to receive messages from variants. Variants are selected from a database by a variant selector operating on a document composition server. The variants are selected based on selector data. The messages of the selected variant are placed into the message zones of the touchpoint and rendered for distribution to customer devices. When a variant at a higher level in the hierarchy is edited by the content creator, the system automatically updates dependent variants.

Abstract: A method and instrumentation for performing a patellofemoral arthroplasty orthopaedic procedure includes coupling an anterior cutting block to a femur of a patient such that the cutting block references local anatomy of the femur. The anterior cutting block is used to perform a number of bone cuts to establish a trochlear cavity in the femur. The trochlear cavity is formed such that a trochlear prosthesis may be inset into the cavity and substantially flush with the surrounding cartilage. A finishing burring guide and burr bit may be used to detail the shape and/or size of the trochlear cavity. Additionally, a trochlear drill guide may be used to facilitate establishing peg holes in the patient's femur to receive corresponding pegs of the trochlear prosthesis.

Abstract: Various embodiments of a non-powered actuator arm for controlling liquid flow to a fluid-filled lens are described herein. A vertical tweezer assembly compresses a reservoir of solution in a first vertical direction by lateral disposition of a slider mounted on the outside of the housing. The assembly may also be shaped to provide compression of the reservoir in a second horizontal direction by lateral disposition of a slider. In another embodiment, a housing may contain a piston that moves laterally within the housing and collapses the reservoir disposed adjacent to the piston and also within the housing. The housing may contain a plurality of compressible domes which can each be compressed to cause a local compression on the reservoir disposed within the housing. Compression of the reservoir causes liquid inflation of a lens module.
