Abstract: The disclosed computer-implemented method for navigating through a hierarchy of nodes stored in a database may include (1) receiving a request to access a database that stores a set of nodes organized in a hierarchy, wherein the hierarchy is divided into contiguous subsections and each subsection is stored in a separate page and (2) in response to the request, traversing a path through the hierarchy of nodes by (a) identifying an initial node in the path and looking up an initial page that contains the initial node, (b) loading the page from the database into local memory, the page including the initial node in the path and one or more subsequent nodes in the path, and (c) navigating to the one or more subsequent nodes in the path by accessing the page loaded into local memory instead of accessing the database. Additional methods, systems, and computer-readable media are also disclosed.

Abstract: Intelligent motion capture element that includes sensor personalities that optimize the sensor for specific movements and/or pieces of equipment and/or clothing and may be retrofitted onto existing equipment or interchanged therebetween and automatically detected for example to switch personalities. May be used for low power applications and accurate data capture for use in healthcare compliance, sporting, gaming, military, virtual reality, industrial, retail loss tracking, security, baby and elderly monitoring and other applications for example obtained from a motion capture element and relayed to a database via a mobile phone. System obtains data from motion capture elements, analyzes data and stores data in database for use in these applications and/or data mining. Enables unique displays associated with the user, such as 3D overlays onto images of the user to visually depict the captured motion data. Enables performance related equipment fitting and purchase.

Abstract: A computer-based system and method provide truck-rental information and expertise-based guidance to facilitate a customer's reserving and renting of a truck using a communications network. The system includes a server which processes user inputs from a user's computer over a communications network and provides information responsive thereto to the user's computer over the communications network from which a service contract is generated and confirmed. The server includes a memory and programming. In the memory, a plurality of data sets is stored relating to (a) trucks which can be rented and associated rental prices for the trucks, (b) towing accessories that can be rented and towed vehicles with which the towing accessories can be used, (c) towing accessories and associated rental prices for the towing accessories, (d) expertise-based guidance relating to trucks, and (e) expertise-based guidance relating to towing accessories.
