Abstract: Systems, devices and methods are provided to compress data, and in particular to code and decode data in a PDA. One aspect of the present subject matter is a data structure. The data structure includes a field representing a decoding structure to decode canonical Huffman encoded data, and a field representing a symbol table. The decoding structure includes a field representing an accelerator table to provide a 2N-deep direct-index lookup to provide high-frequency symbols for high-frequency data and to provide bracketing indices for low-frequency data. The decoding structure also includes a field for a binary search table to provide a low-frequency symbol index using a binary search bounded by the bracketing indices provided by the accelerator table. The symbol table is adapted to provide a symbol associated with the low-frequency index.

Abstract: A system and method for constructing an R-Tree index structure, and packing spatial data in the structure to permit parameters of the R-Tree to be constructed to be selected, within provided ranges, by an operator of the system. The spatial data features to be packed into the R-Tree constructed, are sorted, according to fractal geometry, and placed in a table of records. Each record is individually selected from the table, and data associated with each record is temporarily stored in one of a plurality of buffer storage locations according to a plurality of packing algorithms. The data in a buffer storage location is split, into first and second groups of data, upon the occurrence of one of a plurality of predetermined conditions. Data is selectively removed from the buffer for placement in the R-Tree being packed, such that data representing nearby geographical areas is most optimally clustered together. A portable electronic device such as a navigational aid, has a processor, a display, an input, and a memory, all housed by a housing, wherein the memory has spatial data indexed by an R-Tree index embedded therein.

Abstract: A electronic navigation device utilizing a desired orientation to adjust an electronic map displayed on the device. Acquiring global positioning system data, a processor calculates the current position of the navigation device. Scanning into cartographic memory located in memory, the processor locates a predefined thoroughfare containing or most adjacent the calculated position. Utilizing points located nearest the calculated position, the processor establishes the heading of the thoroughfare at that location. The processor adjusts the orientation of the map display to reflect the calculated heading of the adjacent thoroughfare. The processor continues to update the current position and the heading of the map display on a real time basis.

Abstract: A mobile support unit such as an IV stand or the like coupled to a mobile hospital bed, gurney or wheelchair by a latch mechanism which provides hands free operation thereby avoiding the need for a nurse or care provider to manually manipulate the latch to secure the units together for tandem transport. Further, the latch mechanism according to this invention includes a clutch which prevents relative movement of the IV stand or support unit with respect to the hospital bed during transport up to a specific adjustable torque level thereby avoiding the problem of the IV stand or support unit swinging freely relative to the bed during movement. Further, the clutch permits movement of the IV stand or support unit through an arc relative to the bed when a specified force is applied as required by the nurse or care provider to reposition the stand or support unit relative to the bed and provide increased access to the patient or the like. The IV stand includes a relatively heavy base which provides a low center of gravity for the unit and offers a very stabile mobile IV stand which resists tilting or tipping during transport.

Abstract: A stapler mechanism is described which contains a stapling assembly, and anvil assembly, firing means and knife means. These means are activated by a firing trigger. The anvil assembly is closed upon the stapling assembly by means of a closure trigger. The firing trigger is inoperable until the closure trigger has been activated. Another mechanism in the stapler is capable of locking the closure trigger after use so it does not spring open inadvertently before actuation of the firing trigger. Additionally, the stapler mechanism allows forward motion of both triggers and also is capable of allowing reverse motion of the closure trigger to open the mechanism. Furthermore, the stapler mechanism contains means for obstructing the flow of insufflation gasses or bodily fluid from the surgical site through the instrument during endoscopic surgery.

Abstract: The storage space required for representing geographic features is reduced by determining an optimum number of bits that can be used to store coordinate data along each separate axis. Any coordinate change that cannot directly fit within the optimum bit size is subjected to an escape sequence made up of one or more special values and a normal value that fits in the optimum bit size. The special values are obtained by a predetermined calculation for each bit size. If all changes for one axis are in the same direction and special values are not needed, a global sign can be used to further enhance use of the available space on the storage medium.

Abstract: A portable electronic navigational aid device and method calculates estimated time en route and estimated time of arrival. A user inputs a plurality of variables, including identity, cartographic data, final destination. Upon receiving the inputs, the device determines from cartographic data the estimated distance to the final destination and the type of thoroughfare the inputted trip will traverse. During operation, the device recalls the average driving velocity for the inputted driver over each different type of thoroughfare traversed. Using prestored average velocity data, the device calculates an initial estimated time en route and an estimated time of arrival for a desired route. The device continues to receive GPS data as to the driver's position and velocity and updates the average velocity record for that driver on the specific type of thoroughfare. As the average velocity fluctuates, the device adjusts the estimated time en route and the estimated time of arrival. The device further has control processes for potentially erroneous sampling. The device has a predetermined threshold in which data inputs below that threshold will not be averaged into the memory. The second control process of the present invention allows for zero velocity sampling without necessitating a reset of the entire system. If the device samples a zero speed, it will not average that velocity into the system as explained above. Rather, a stop time measured by a counter will be added to the estimated time en route and estimated time to arrival.
