Abstract: The present disclosure relates to a battery electric dump truck, comprising a frame, a dump body pivotably mounted on the frame, a power unit comprising a battery, the power unit providing electrical energy to at least one electrical propulsion motor of the battery electric dump truck, and a charging interface unit is provided separately from the power unit and connected to the power unit by wiring.

Abstract: A software program, for use on a computing device such as a Personal Digital Assistant (PDA) device, is provided to a health care provider (HCP). The software program configures the computing device with means for inputting profile information regarding patients and means for comparing the patient profile information against a database containing information regarding one or more drug studies performed on patients having similar medical histories and/or symptoms. The patient information is compared against the database, and, where appropriate, the healthcare provider is made aware that the patient associated with the patient profile could benefit from being prescribed to take the drug or drugs on which the study is based, and/or at a particular dose indicated by the study.

Abstract: A method and apparatus for rapid distribution of information whereby information gathered from an ongoing conference is incorporated into a single, electronic file. The file may be an interpretable data file, or a personal digital assistant (PDA)-executable application file created to include both the information sought to be distributed, and viewer software for displaying the information via a PDA device. The application file may be created from an easily-created document through a GUI-driven software application for gathering information from a user, manipulating data, and interacting with commercially available code development software, which typically requires a high level of user experience or training, to automate the otherwise complex application development process. The application file may include a checksum to prevent distribution and/or display of altered information. The file is distributed at the conference via wireless transmission to attendees' PDA devices via a beaming station.

Abstract: A method and apparatus for electronic administration of an exercise regimen. The exercise regimen is prepared electronically by a therapist via a therapist interface displayed by an electronic device such as a PDA. The exercise regimen is customizable for the patient. Related exercise information may be retrieved and delivered to the patient in addition to the exercise regimen by wireless transmission to the patient's electronic device, such as a PDA, for viewing via a patient interface. The patient interface's display of information may be customized to present images and instructions specific to the exercises selected by the therapist and to display the name of the therapist and/or therapist contact information to allow for resolution of questions/concerns. Additionally, reminder messages may be provided to the patient to prompt performance of the exercises in accordance with the therapist-specified schedule. The therapist and patient devices may be configured to display selected advertising indicia.

Abstract: A matrix for holding the electrolyte within a phosphoric acid fuel cell is made from silicon carbide and a binder of polyestersulfone. Preferably the matrix consists of 10-20 weight percent polyethersulfone with a balance of silicon carbide. The matrix has improved strength, wettability and bubble pressure compared to the best known prior art matrix.

Abstract: A seal material especially adapted for phosphoric acid fuel cell stack sealing is described comprising an unfilled, unoiled high molecular weight polytetrafluoroethylene. Although the seal material is especially adapted as the regular seal around the plenums separating the oxygen and hydrogen gas inlets and outlets, it can also be used as a plenum or stack crack sealer. The material provides seal integrity and stability at temperatures in excess of 400.degree. F. (204.degree. C.)., e.g. 400.degree. F. to 450.degree. F. (204.degree. C. to 232.degree. C.), in a corrosive chemical environment at differential pressures above 50 psi (e.g. 50 psi to 80 psi). It can be used in electrochemical cells in general where high temperature, high pressure, corrosive environments prevail.

Abstract: A thermally conductive caulk particularly suited for use in a phosphoric acid fuel cell is made by mixing graphite into a stable aqueous dispersion of polytetrafluoroethylene and fluorinated ethylene propylene such that the solids floc to form a paste. The paste is applied to the part to be caulked and then dried and heat treated. Caulks made according to the present invention have good thermal conductivity and absorb very little phosphoric acid.
