Abstract: An Archimedean screw turbine generator of increased efficiency is disclosed. Rather than having the helical flighting of the turbine perpendicular to the central torque tube, this design incorporates cupped or cambered flighting. This increases the turbine's overall efficiency, as well as its efficiency across a broad range of fluid flows. The improved Archimedean screw turbine produces efficient power from about 5 percent of design flow to about 110 percent of design flow. In addition, design flow efficiency is 9-10 percent better than existing Archimedean screw generators. Prior art turbines of the Archimedean screw type operate efficiently only near design-rated flows. Most are turned off if flows drop more than 30 percent below deign-rated flow figures. For a presently-preferred embodiment of the invention, the screw axially rotates within a close-fitting half pipe. A three-phase permanent-magnet AC servo motor is used as a generator.

Abstract: A freezing of gait cue apparatus that provides a visual cue, and a method for providing a visual cue, upon detection of a gait irregularity. The gait irregularity, such as a freeze of gait (FOG) for sufferers of neurological diseases like Parkinson's disease, is determined by a processor in communication with a motion sensor worn by the sufferer. When the gait irregularity is determined the apparatus projects a laser light beam on the ground in front of the user of the apparatus to cue them to continue walking.

Abstract: Apparatus for replacing underground pipe is described, including a resistance plate from which a pair of hydraulic cylinders extend perpendicularly in parallel with each other. The cylinders operate cyclically with a pulling bridge having a cable gripper to provide a sequence of pulling strokes to a cable pulling a mole. The mole pulls a replacement pipe behind it through the old pipe, which has been burst, slit, or otherwise expanded by the mole. The resistance plate is provided with a slot, and the cylinders are positions such as to allow the mode to be pulled substantially completely into the apparatus. A holding bridge is releasably mounted spanning the slot in the reaction plate to position a second cable gripper for holding the cable on return stroke of the pulling bridge. The holding bridge may be removed at the end of the pulling operation to accommodate the mole.

Abstract: The invention is directed to a material loader for quickly and easily loading material, particularly bulk material, into a containment apparatus. Material to be loaded is placed inside a bin that is dimensioned to fit inside the containment apparatus. In use the containment apparatus is positioned so that the bin is inside the containment apparatus and the containment apparatus or a vehicle bearing the containment apparatus is connected to a material transfer member inside the bin. Forward movement of the containment apparatus/vehicle causes the material transfer member to hold against the material while the bin slides out of the containment apparatus from the point of view of the containment apparatus, leaving the material behind. In other words, the forward movement of the containment apparatus/vehicle causes the material transfer member to pull the material into the containment apparatus. The invention may also be used for unloading a containment apparatus.

Information stored within and specific to the microprocessor is accessed. The information can comprise coefficients of a quadratic approximation of a frequency-voltage characteristic of the microprocessor for a set of body biasing conditions. An efficient voltage for operating the microprocessor at the desirable operating frequency is computed. The microprocessor is operated at the efficient voltage and the set of body biasing conditions.

Abstract: A container body has a closed bottom and a peripheral wall defining a hollow interior for receipt of desired contents. A cap for the container has a depression constructed and arranged to fit tightly over a top rim of the container body to seal the contents within the hollow interior. The cap can be pried upward to an open position to allow access to the hollow interior. An opening tab hinged to the cap normally extends downward alongside the container body when the cap is closed, but is swingable upward to a horizontal orientation. The tab and cap have cooperating abutments that limit further upward swinging of the tab relative to the cap such that the tab can be used to pry the cap open.

Abstract: In one form the invention provides a method of modifying a data file for transmission over a data network. The method comprises the steps of receiving the original data file and creating a header file, the header file including the length in bytes of the original data file. At least one repetition byte sequence is identified within the original data file, the repetition byte sequence comprising a byte value that is repeated consecutively within the repetition byte sequence. A modified data file is created by replacing the repetition byte sequence with a repetition marker, the repeated byte value, and a repeat frequency value representing the number of times the repeated byte value occurs within the repetition byte sequence. The repetition marker is added to the header file. The invention further provides a method of transmitting a data file to a remote device over a data network.
