  • Patent number: 11971716
    Abstract: Aspects of the disclosure relate to controlling a vehicle in an autonomous driving mode. For instance, a first location corresponding to a location where the vehicle is to pick up or drop off a passenger is received. A first cost for the vehicle to reach the first location is determined. A second location based on the first location is identified, and a second cost is determined based on a cost for the vehicle to reach the second location and a cost for the passenger to reach the second location. The first cost is compared to the second cost, and a notification is sent based on the notification. In response to sending the notification, instructions to proceed to the second location are received, and in response to receiving the instructions, the vehicle is controlled in the autonomous driving mode to the second location to pick up or drop off the passenger.

  • Publication number: 20240118463
    Abstract: A light control film comprises a light input surface and a light output surface opposite the light input surface. Alternating transmissive regions and absorptive regions are disposed between the light input surface and the light output surface. The absorptive regions have an aspect ratio of at least 30 and the alternating transmissive region and absorptive regions have a relative transmission at a viewing angle of 0 degrees of at least 75%.

  • Patent number: 11947135
    Abstract: A light control film is described comprising alternating transmissive regions and absorptive regions disposed between a light input surface and a light output surface. The absorptive regions have an aspect ratio of at least 30. In some embodiments, the alternating transmissive regions and absorptive regions have a transmission as measured with a spectrophotometer at a viewing angle of 0 degrees of at least 35, 40, 45, or 50% for a wavelength of the range 320-400 nm (UV) and/or at least 65, 70, 75, or 80% for a wavelength of the range 700-1400 nm (NIR). In another embodiment, the absorptive regions block light at the light input surface and light output surface and the maximum surface area that is blocked is less than 20% of the total alternating transmissive regions and absorptive regions. Also described are various optical communication systems comprising the light control films described herein and methods.

  • Patent number: 11940689
    Abstract: A light control film comprises a light input surface and a light output surface opposite the light input surface; alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface, wherein the absorptive regions comprise a core having a first concentration, C1, of a light absorbing material sandwiched between cladding layers having a second concentration, C2, of the light absorbing material, wherein C2<C1, and wherein the cores have an aspect ratio of at least 20.

  • Publication number: 20160253633
    Abstract: A method of generating home repair estimate reports from subjective home or other building inspection reports may be provided. Such a method may allow preliminary high-level estimation of building repair costs, and may require uploading the inspection report and building and location data, generating a calibration model and location indexing information, extrapolating the sectional deficiencies identified in the inspection report, mapping the deficiencies to the building model, and applying the indexing information.

  • Patent number: 8516480
    Abstract: Virtualization snapshots are utilized for efficiently synchronizing virtual machines present on a client system and a server system. A snapshot of a virtual machine (VM) is taken by the client system before making modifications to the VM. The modifications to the VM are stored by the virtualization snapshot separate from the VM itself. The modified portions of the VM are communicated by the client system to the server system. The server system applies the modifications to a locally stored VM that corresponds to the original VM on the client system. The modified VM on the server system matches the modified VM on the client. As a result synchronization between the VMs on client system and the server system is obtained without transferring the entire VM multiple times. The server system performs format conversions between a format of the client system and the server system on the VM.

  • Publication number: 20070203886
    Abstract: A method and apparatus for accelerating and improving access to network files is provided. One technique for providing data quickly and efficiently is to send a thumbnail of a file to a user rather than sending the entire file. Another technique for providing data quickly and efficiently is to generate the difference between a current version of data and a non-current version of data, to transmit this difference to the requesting user, and to use the difference to update the non-current version of data the user currently has access to. A third technique that can be used in combination with the first two techniques is to compress data, such as the thumbnail or file difference, before transmitting this data. A fourth technique that can be used in combination with the third technique is to securely transmit the compressed data.

  • Patent number: 6993590
    Abstract: A method and apparatus are provided for capturing and managing user-specific data, where the user-specific data contains information on the user's interaction with the Net. The method generally involves using a proxy to capture or cause to capture the user-specific data and then storing the user-specific data. The user-specific data may be used to customize the contents of electronic information delivered to the particular user.
