  • Publication number: 20250115263
    Abstract: A method for a replay driver skill improvement system is described. The method includes logging vehicle commands requested by a vehicle operator of an ego vehicle to perform a selected driving maneuver. The method also includes identifying one or more of the logged vehicle commands in which operation of the ego vehicle is outside of a predetermined threshold while performing the selected driving maneuver. The method further includes operating the ego vehicle according to the logged vehicle commands until the one or more of the logged vehicle commands in which operation of the ego vehicle is outside of the predetermined threshold are reached. The method also includes performing, through shared control with the vehicle operator, improved vehicle commands to complete the selected driving maneuver while operating the ego vehicle at or within the predetermined threshold.

  • Patent number: 9181530
    Abstract: The invention relates to the discovery of an HEV strain from a chronically infected patient. The virus grow unusually well in numerous cell cultures. Thus, the invention provides cell cultures, vectors, and vaccine compositions based on the virus. The invention relates, in part, on the identification of a new strain of HEV genotype 3 virus. Strain Kernow-C1 (genotype 3) of HEV, which was isolated from a chronically infected patient, was used to identify human, pig and deer cell lines permissive for infection. Adaptation of the Kernow-C 1 strain to growth in human hepatoma cells selected for a rare virus recombinant that contained an insertion of 174 ribonucleotides (58 amino acids) of a human ribosomal protein gene and additional mutations.

  • Patent number: 7083757
    Abstract: Semiconductor wire bonding tools used in the assembly and interconnection of integrated circuits (ICs) are micromolded from a mixture of ultrafine particulate materials mixed with an organic binder. Following extraction of the binder the green bonding tools are sintered during which they undergo isotropic, constant and accurately predetermined shrinkage. Hence semiconductor wire bonding tools can be produced with virtually no limit to miniaturization, thus allowing the fabrication of higher integrated semiconductor products.

  • Patent number: 6770242
    Abstract: Permanent magnet for voice coil actuator motors used to actuate head-arm assemblies in small form disk drives are produced from a dispersion of prealloyed rare earth magnetic particles in a thermoplastic binder. Upon shaping of green parts the magnetic axis of the particles is aligned with the field lines of a magnetic field. Following extraction of the binder the green parts are sintered to net shape. Improved magnetic properties, smaller dimensions, better than tolerances and 100% material utilization are claimed.

  • Publication number: 20020135108
    Abstract: A method to produce polycrystalline sapphire or ruby watch jewels is disclosed. Green watch jewels are formed from a mixture of fine ceramic powders with a thermoplastic binder. Following extraction of the binder the parts are sintered to net shape and full density. The method obviates the inefficient and labor intensive technique of monocrystalline watch jewel manufacturing. The purity of the raw materials and processing conditions result in sintered polycrystalline rubies or sapphires with homogeneous microstructures, small grain size and hardness similar to that of their synthetic monocrystalline counterparts.
