Abstract: Systems, devices and methods are provided for more efficient use of RAM and other resources in connection with a route calculation algorithm which quickly obtains a best or reasonable best path between two locations. The navigational aid device includes forced layer switching capabilities. The navigational aid device includes a processor and a memory adapted to communicate with the processor. The memory has cartographic data including any number of locations and data indicative of thoroughfares of a plurality of types connecting certain ones of the locations. The plurality of thoroughfares are organized in a hierarchy of detail levels. The processor operates on a route calculation algorithm to find a path between any two of the number of locations and the route calculation algorithm dynamically forces switching between different levels in the hierarchy of detail levels based on a set of criteria.

Abstract: A method and apparatus are provided for calculating potential paths through a roadway network defined at least partially by separate, but adjacent data maps. First and second data maps are provided that are indicative of roadway networks for different geographic regions bounded by region edges, at least one of which is common to both geographic regions. The data maps are adjacent, and one data map contains the first location while the other data map contains a roadway segment over which the potential paths may travel. Potential paths are planned from the first location through the first data map. When a current potential path intersects an edge of the first data map, the intersection is identified by coordinate data. A transition point is located in an adjacent data map based on the location where the current potential path intersects the edge of the first data map. The calculation method and apparatus continue from the transition point through the second data map toward the second location.

Abstract: A method and apparatus are provided for calculating potential paths between source and destination locations. First and second map databases are provided that are indicative of roadway networks for geographic regions bounded by region edges and containing source and destination locations. The first and second map databases, are non-adjacent, non-contiguous such that the region edges of the first map database are separate and distinct from region edges of the second map database. Potential paths are calculated through the roadway network of the first map database up to a node or segment at which each potential path intersects a region edge of the first map database, thereby defining a node/edge coordinate. A transition location is obtained in the second map database that geographically corresponds to the node/edge coordinate at which a given potential path intersected the region edge of the first map database.

Abstract: Systems, devices and methods are provided for an improved navigational route planning device which provides more understandable, accurate and timely route calculation capabilities. The navigational aid device with route calculation capabilities includes a processor connected to a memory. The memory includes cartographic data and a desired destination, the cartographic data including data indicative of thoroughfares of a plurality of types. A display is connected to the processor and is capable of displaying the cartographic data. The device is adapted to calculate a route to navigate to the desired destination. And, the device is adapted to adjust a starting point for the route calculation to an appropriate location such that the device is on the route at a time when the route calculation is completed. The device processes travel along the route, recognizes when the device has deviated from the route, and calculates a new route to navigate to the desired destination.

Abstract: A computing platform 20 provides multiple computing environments 24 each containing a guest operating system 25 provided by a virtual machine application 26. Optionally, each computing environment 24 is formed in a compartment 220 of a compartmented host operating system 22. A trusted device 213 verifies that the host operating system 22 and each guest operating system 25 operates in a secure and trusted manner by forming integrity metrics which can be interrogated by a user 10. Each computing environment is isolated and secure, and can be verified as trustworthy independent of any other computing environment.

Abstract: A pinch clip occluder for infusion sets is disclosed including a housing and a clamp movably disposed within the housing to selectively occlude an infusion set. In one embodiment the clamp has at least one arm which moves between first and second positions to pinch closed a silicone tube of the infusion set unless the pinch clip occluder is held in an open position by the user, or placed in a receptacle which will hold the pinch clip occluder in an open position. In another embodiment a plunger is disposed so as to intersect a passage passing through the housing. As the plunger is selectively moved between first and second positions, the flow through a tube in the passage is selectively controlled. Such an arrangement prevents a free-flow condition from occurring through the infusion set.

Abstract: A self-cooling beverage container system. The system includes a can, and an external chamber coupled to the bottom of the can for containing compressed gas therein. Helical tubing in the form of a single or double helix resides within the can. A first open end of the tubing is disposed in communication with the external chamber, and an opposing terminal end of the tubing is closed, preferably being accessible with a pull-tab as presently known in the field for opening a vessel responsive to pulling action by a user. When the terminal end of the tubing is opened it communicates with atmosphere, permitting the compressed gas to flow from the external chamber through the tubing and into atmosphere. The gas expands as it flows, thereby withdrawing heat from the surrounding beverage in which the tubing is submerged to cool the beverage.

Abstract: A clamp having an attachment mechanism for holding and positioning a second object attached to the clamp relative to a first object secured by the clamp. The clamp includes a clamping member for securing the first object and an attachment mechanism for holding the clamp to the second object. The clamping member includes a scrape preventive mechanism. The attachment mechanism includes a positioning member for positioning the second object relative to the first object without detaching the second object from the clamping member. The attachment member is hand operable.
