Abstract: A browser is provided in which the color of a selected linking word in a document is changed to a color that indicates the relative order in which the linking word was selected. As an example, consider a document with three hyperlinking words and the colors red, yellow and green, with red specifying the most recent hyperlink selected, yellow the next most recent, and green the least recent of the three. When the first linking word is selected, its color is changed from, for example the prior art blue, to red when the user drills back to the original web page document. When the next link is selected, it is colored red when the user returns to the original document and the first selected linking word is colored yellow. When a third hyperlinked word is selected, it is colored red on return, the first selected hyperlink word, which was yellow, is colored green, and the second selected hyperlink word, which was red, is colored yellow.

Abstract: A digital signal processing system for multiplexing/demultiplexing a large number of closely spaced FDM channels in which sub-band definition filtering divides the FDM spectral band comprised of "N" channels into "K" sub-bands in order to reduce the dimension of the polyphase filter fast Fourier transform structure required to complete the multiplexing/demultiplexing. This reduces the order of the required prototype filter by a factor proportional to K. The number of sub-bands K is chosen so that it is large enough to ensure the polyphase filter, fast Fourier transform structure for each sub-band is realizable within a finite word length, fixed point arithmetic implementation compatible with a low power consumption. To facilitate efficient sub-band definition filtering, the real basebanded composite signal is inputted at a spectral offset from DC equal to one quarter the FDM channel bandwidth for the N channels and the signal is sampled at a frequency 50% greater than the applicable Nyquist rate.

Abstract: A weather monitoring, measuring and reporting system which uses unattended, high-resolution digital cameras and laser rangers to both measure and display weather conditions in a local region, such as the region surrounding an airport. Visibility is estimated by processing images in the camera's field of view at known range distances. The light response of the camera is matched to the light response of the human eye. In a preferred embodiment of the invention, the camera generates a digital pixel image of range objects; that is, prominent terrain objects such as, buildings, water towers, etc. in the camera's field of view. The digital pixel values of these range objects are stored in system memory at known address locations. The contrast between an average background pixel value in a region adjacent to an object and the average object pixel value is used to determine if the object is visible.

Abstract: A computer system referred to as a Database Management System with Nested Time Axes (DBMS with NTA), which cooperates with a Computed Medical File and Chart System (CMFCS), employs data processing techniques to solve problems related to data collection and analysis in daily medical practice. It reconstructs irregularly or regularly collected data and places it into a database table with a standardized time axis acceptable for the CMFCS. Multiple records of an original database at irregular intervals are correlated to a progeny database with a standardized time axis by averaging, maximizing and minimizing. The DBMS with NTA consists of several database tables, each of which has a relational time axis, and corresponding programs to reconstruct a root database table to a progeny database table in hierarchical order.
Abstract: A ratchet wrench includes a handle, a housing attached to said handle, a ratchet gear mounted for rotation in said housing, the ratchet gear having an axis of rotation extending through the housing, and means connected to the ratchet gear for turning a threaded fastener. A pawl is mounted on the handle about a pivot axis that extends through the handle, the pawl pivoting among a first position in which the pawl permits unrestricted rotation of the ratchet gear, a second position in which the pawl engages the ratchet gear to prevent rotation of the ratchet gear in one direction, but allows rotation of the ratchet gear in the opposite direction, and a third position in which the pawl engages the ratchet gear to prevent rotation of the ratchet gear in the opposite direction, but allows rotation of the ratchet gear in the one direction. A method for turning a threaded fastener is also included.
Abstract: A rotor is comprised of laminations forced on a shaft that has two staking rails, which penetrate the laminations and create two holding points. The two staking rails are positioned on the shaft at an angle to force the lamination toward the center of the shaft and force it hard against a flat on the shaft. This assembly provides for "zero" rotational movement without additional steps in the manufacturing process. An additional feature of the assembly is that the flat on the shaft relates to flats on the rotor to which the permanent magnets are attached, and a flat on the shaft for mounting an encoder, which flats are all in the same plane. This allows the motor to be easily aligned, which is a requirement to properly phase motor rotation to motor commutation.
