  • Patent number: 10606241
    Abstract: A process planning apparatus based on augmented reality (AR) includes: a camera set capturing color and depth images of a processing machine and a probe operated by a human user in a real scene; a processor, which is signal-connected to the camera set and the processing machine, creates spatial intelligences for motion planning of the probe operated by the human user in an AR environment that combines a virtual workpiece with the real scene, and generates instructional data from the spatial intelligences to guide the human user to operate the probe to produce machine motion data for a manufacturing task; and an output interface, which is signal-connected to the processor and outputs scene data, the virtual workpiece and the instructional data to the human user.

  • Publication number: 20070224656
    Abstract: The present invention is based on the findings that BACE2, a homolog of ?-secretase BACE, is able to stimulate processing of APP in a non-amyloidogenic pathway, thereby suppressing the level of A?. Accordingly, the present invention provides methods and means for the identification and use of modulators of this unique activity of BACE2 to suppress A? production. The compounds identified using the methods and means provided herein may be used as potential candidates for the treatment of Alzheimer's disease and other neurological diseases.

  • Publication number: 20060183160
    Abstract: The invention concerns a novel ?-secretase, a method of partially purifying this novel ?-secretase, and its use in assays to screen for potential drug candidates against Alzheimer's disease and other neurological diseases. The novel ?-secretase has an estimated molecular weight of about 32-39 kDa or 22-26 kDa in HEK293 cell membrane extracts and human brain samples, respectively, as calculated from radiation inactivation analysis, and has a pH optimum at about pH 6.5-7.0.
