  • Publication number: 20210271003
    Abstract: An optical element including an array of microlenses, a pinhole mask, and a wavelength selective filter is described. The pinhole mask includes an array of pinholes with each pinhole in the array of pinholes aligned with a microlens in the first array of microlenses. The wavelength selective filter is adapted to transmit a first light ray having a first wavelength and transmitted from a first microlens in the array of microlenses through a first pinhole in the array of pinholes aligned with the first microlens, and to attenuate a second light ray having the first wavelength and transmitted from the first microlens through a second pinhole in the array of pinholes aligned with a second microlens in the first array of microlenses adjacent to the first microlens.

  • Patent number: 10978682
    Abstract: A method for fabricating a solid state battery device. The device can include electrochemically active layers and an overlaying barrier material, with an inter-digitated layer structure configured with a post terminated lead structure. The method can include forming a plurality of battery device cell regions (1-N) formed in a multi-stacked configuration, wherein each of the battery device cell regions comprises a first current collector and a second current collector. The method can also include forming a thickness of a first and second lead material to cause formation of a first and second lead structure to interconnect each of the first and second current collectors associated with each of the plurality of battery device cell regions and to isolate each of the second current collectors extending spatially outside of the battery device cell region within a first and second isolated region, respectively.

  • Patent number: 10586974
    Abstract: A pulsed laser can be used to ablate the desired thin film layers at a desired location, to a desired depth, without impinging significantly upon other layers. The battery cell layer order may be optionally optimized to aid in ease of laser ablation. The laser process can isolate layers of thin film within sufficient proximity to at least one edge of the final thin film battery stack to optimize active battery area.

  • Patent number: 7324867
    Abstract: Predictive models of physical parts of the laser processing system part determined. These predictive models are used to determine how the physical system will actually react. The predicted reaction from the models is used as feedback in order to produce the control signals. These physical models therefore adjust to the operation of the system, much in the way that actual feedback would adjust the operation of the system. However, the system may be used at faster speeds, where the actual feedback could not be produced fast enough. Different kinds of modeling are described, including in-position feedback which models sharp movements of the laser system, trajectory models which superimpose the commanded curve over the predicted actual curve to determine errors in trajectory, and constant/variable energy density controls.
