  • Publication number: 20210336471
    Abstract: Method for active battery management to optimize battery performance. The method includes providing signal injections for charging and discharging of a battery. The signal injections include various charging and discharging profiles, rates, and endpoints. Response signals corresponding with the signal injections are received, and a utility of those signals is measured. Based upon the utility of the response signals, data relating to charging and discharging of the battery is modified to optimize battery performance and to determine when to discharge the battery into a power grid in order to return power to the grid in exchange for an economic benefit such as a payment or rebate from a utility company.

  • Patent number: 11116090
    Abstract: Electronic Devices Incorporating Flexible Component Layers with Interlocking Devices At least some aspects of the present disclosure directs to an electronic device 100 comprising a rigid member 100A, 100B, a flexible component layer 130, and an interlocking device 110A, HOB disposed between the flexible component layer and the rigid member. The flexible component layer has at least two sections when the flexible component layer is flexed. The interlocking device comprises a first interlocking component attached to or integrated with the flexible component layer, and a second interlocking component attached to or integrated with the rigid member configured to engage with the first interlocking component, such that the engagement prevents the separation of the flexible component layer from the rigid member along a direction generally perpendicular to a surface of the rigid member.

  • Patent number: 10431635
    Abstract: A flexible OLED display device that includes an upper module having a cover window film, a lower module, and a display module between the upper and lower modules. The display module includes an OLED and an OLED substrate. The stiffnesses of components in the display device are controlled to satisfy a particular relationship such that the bending stiffnesses of the upper and lower modules are tuned in order to position the neutral bending plane below the display module, which places the display into a state of compressive strain as opposed to zero strain. This design is suitable for a bifold flexible display in which the upper module can be folded to face itself.

  • Patent number: 9944031
    Abstract: Molded optical articles and methods of making them are disclosed herein. Optical articles comprise a photopolymerizable composition disposed on a major surface of a substrate. The photopolymerizable composition comprises: a silicon-containing resin comprising silicon-bonded hydrogen and aliphatic unsaturation, and a platinum catalyst providing from about 0.5 to about 30 parts per million of platinum. The major surface imparts a positive or negative lens to the photopolymerizable composition. Optical articles also include those that have been photopolymerized using actinic radiation having a wavelength of 700 nm or less.
