  • Patent number: 12249001
    Abstract: The present application discloses systems, methods, and computer-readable media that can dynamically control a number of provider devices operating in a prioritized-dispatch mode by determining a range of prioritized-dispatch-mode slots for a target time based on differences between value metrics received by provider devices operating in multiple dispatch modes and sending availability nudges to provider devices based on the range of prioritized-dispatch-mode slots. For instance, the disclosed systems can generate a threshold-noticeable-value difference between historical value metrics received by provider devices while operating in a prioritized-dispatch mode and in a basic-dispatch mode. Based on the threshold-noticeable-value difference, the disclosed systems determine a range of slots for the prioritized-dispatch mode during a target time period for a geographic area.

  • Patent number: 12061018
    Abstract: A method for full spectrum solar thermal energy harvesting and collection includes storing a first heat in a phase change material in the presence of solar radiation based on absorbing full spectrum solar radiation, harvesting a second heat from the phase change material in the presence of solar radiation, storing molecular energy in a molecular storage material in the presence of solar radiation based on absorbing full spectrum solar radiation, transferring the second heat from the phase change material to the molecular storage material in the absence of solar radiation, and harvesting the molecular energy released by the molecular storage material.

  • Patent number: 11964230
    Abstract: A system configured to capture CO2 and able to be washed of the captured CO2 includes a material including an ionic liquid configured to capture CO2 in response to exposure to a gas comprising CO2 and to a thermal energy source and an aerogel holding the ionic liquid therein. The system may also include a washing solution configured to wash the captured CO2 from the material.

  • Publication number: 20230146045
    Abstract: Methods for fabricating flexible/stretchable circuits can include identifying one or more regions of a printed circuit board (PCB) for selectively removing insulation material. The PCB can include one or more electrically conductive structures arranged on an insulation layer. The method can include applying, within each region of the one or more regions, thermal energy via a heat source to a surface of the PCB within the region such that insulation material of the insulation layer is removed from the region while a portion of the insulation layer beneath the one or more electrically conductive structures is maintained. The flexible/stretchable circuit can be laminated on a soft actuator to form a soft robotic device.

  • Patent number: 11541349
    Abstract: A method of capturing CO2 and converting the captured CO2 into useful byproducts includes providing a material including a material matrix holding an ionic liquid, exposing the material to a source of thermal energy to capture CO2 within the material, removing the material from exposure to the source of thermal energy, and washing the material with a solution to convert the captured CO2 and wash the converted, captured CO2 from the material as filtrate. Materials and systems for capturing CO2 and converting the captured CO2 into useful byproducts are also provided.

  • Publication number: 20220387675
    Abstract: Systems, methods, and devices having improved conformal properties for biomedical signal measurement are disclosed. A device can have a first polymer substrate coupled to a conductive layer forming a conductive trace electrically coupled to a conductive pad exposed via an opening. The device can have a second polymer substrate forming a first cavity between the first polymer substrate and the second polymer substrate. The device can have a first inlet portion that receives a fluid that expands the first cavity causing the device to conform to an anatomical structure. The structure can be an atrium, such as the left atrium, of the heart of a patient. The device can conform to the walls of the tissue structure, and the conductive pad exposed via the opening can detect a signal from the wall of the tissue structure. The signal can be provided to an external measurement device for processing.

  • Publication number: 20150026462
    Abstract: A method and system for access-controlled decryption in big data stores is provided. In an implementation, a system provides a method for encryption that stores meta-information about sensitive data elements being encrypted in a big data store, such as a Hadoop system, in which the bulk of the data may remain unencrypted. In an implementation, the system reads the stored meta-information at decryption time to determine where the encrypted data is within a large and unencrypted file system, and to determine whether or not an individual user has access rights to decrypt a given element of sensitive data. The system allows fine-grain control over access rights to sensitive data during decryption.
