  • Patent number: 11146699
    Abstract: Methods and apparatuses receive, into a user interface, an instruction to combine multiple scanned pages into one or more n-up sheets. In response to receiving the instruction to combine multiple scanned pages, a resolution field is output from the user interface. A user-set resolution for the scanned pages on the n-up sheets is received into the resolution field. With this, the scanned pages are scanned at the user-set resolution using a scanner. A processor is used to combine the scanned pages together into the n-up sheets at the user-set resolution of the scanned pages resolution, and the processor outputs the n-up sheets in an electronic file.

  • Patent number: 10795145
    Abstract: Infrared and night vision optical fusion systems are provided. The first scheme is to add a common-aperture beam splitter in front of the night vision device, which is a band-pass filter having a high transmission for the light with wavelength of 0.78-1 ?m, and a high reflectivity for the visible light with wavelength of 0.38-0.78 ?m and for the infrared light with wavelength of 8-14 ?m. After electrical processing, a target image with a temperature higher or lower than a certain threshold is obtained on the LCD/OLED. The second scheme is to align the night vision objective lens and the infrared objective lens having the same field of view side by side. Since only infrared targets having a temperature above or below a certain threshold are used, white or red humans, animals and vehicles can be clearly seen in a green night vision background with high contrast no matter which scheme is adopted.

  • Patent number: 10345758
    Abstract: Computer processor controlled energy harvester system. The system uses a plurality of oscillating weight type energy collectors, each configured to store the energy from changes in the system's ambient motion as stored mechanical energy, often in a compressed spring. The energy collectors are configured to move between a first position where the energy collector stores energy, to a second position where the energy collectors release stored energy to a geared electrical generator shaft, thus producing electrical energy, often stored in a battery. A plurality of processor controlled electronic actuators, usually one per energy collector, control when each energy collector stores and releases energy. The processor can use accelerometer sensors, battery charge sensors, and suitable software and firmware to optimize system function.
