  • Patent number: 10101435
    Abstract: The embodiments described herein provide ranging capabilities in RF-opaque environments, such as a jungle, utilizing transponders located on a property line. In particular, the embodiments described herein provide for determining a perpendicular distance to a property line from a ranging device. The transponders are located on the property line and a separated from each other by a known distance. The ranging device transmits RF signals to the transponders, which are received by the transponders and re-broadcasted back to the ranging device on a different frequency. The ranging device uses information about the transmitted and received RF signals and the known distance to calculate a perpendicular distance from the ranging device to the property line.

  • Patent number: 9827978
    Abstract: A traction motor of a hybrid electric vehicle drives a primary pump to provide pressurized hydraulic fluid to engage a power flow path of a multi-ratio transmission. To reduce fuel consumption, the motor is maintained at zero speed until a shift lever is moved into a drive position. After a power flow path is established, the motor speed is again reduced to zero until a driver demands torque by pressing an accelerator pedal. While the traction motor is stationary, an auxiliary pump maintains the fluid pressure to keep the transmission power flow path engaged.

  • Patent number: 8614006
    Abstract: The present invention relates to one-part cationically curable compositions with storage stability, wherein cure is independent of external stimuli such as heat and UV irradiation. In particular, the present invention provides for compositions with a long shelf life that will cure only upon application of the composition to the target surface, i.e. the surface is involved in initiating cure of the cationically curable component. Suitable compositions comprise those for curing on a surface comprising carbon-halogen covalent bonds comprising a cationically curable component and a non-halide silver salt. The present invention also relates to a primer capable of promoting cure of cationically curable non-halide silver salt compositions.

  • Patent number: 8399099
    Abstract: The present invention relates to cationically and radically curable coating compositions for coating a surface. The coating compositions consist essentially of a radically or cationically curable monomer, and a metal salt. The metal salt is chosen so that it is reduced at the surface to be coated, and where the standard reduction potential of the metal salt is greater than the standard reduction potential of the surface, and where when the composition is placed in contact with the surface, the metal salt of the composition is reduced at the surface, thereby initiating cure of the curable component in the compositions. Redox mediated cure of the coating compositions results in a coating or film on the surface. The invention also provides for functionalization of surfaces. Cross-linking of the coating occurs directly on the surface.
