  • Publication number: 20230304860
    Abstract: Aspects relate to a spectral modeling system for building chemometrics (calibration) models for spectral devices targeting ultra-wide-scale deployment. The spectral modeling system includes a spectral converter for generating a plurality of artificial spectra using spectral data of a plurality of samples measured by a subset of a plurality of spectral devices and spectral device characteristics representing spectral variations in the plurality of spectral devices. The spectral modeling system further includes a chemometrics engine for generating a chemometrics model for one or more parameters associated with the plurality of samples based on the spectral data and the plurality of artificial spectra.

  • Patent number: 10055892
    Abstract: Some augmented reality (AR) and virtual reality (VR) applications may require that an “activity region” be defined prior to their use. For example, a user performing a video conferencing application or playing a game may need to identify an appropriate space in which they may walk and gesture while wearing a Head Mounted Display without causing injury. This may be particularly important in VR applications where, e.g., the user's vision is completely obscured by the VR display, and/or the user will not see their actual environment as the user moves around. Various embodiments provide systems and methods for anticipating, defining, and applying the active region. In some embodiments, the system may represent real-world obstacles to the user in the user's field of view, e.g., outlining the contour of the problematic object to call the user's attention to the object's presence in the active region.

  • Patent number: 7639700
    Abstract: An architecture for optimizing network communications that utilizes a device positioned at two edges of a constrained Wide Area Network (WAN) link. The device intercepts outgoing network packets and reroutes them to a proxy application. The proxy application uses persistent connections with a network accelerator device at the other end of the persistent connection. The proxy applications transmit the intercepted data after compressing it using a dictionary-based compression algorithm. Packet mangling may involve spoofing the connection request at each end node; a proxy-to-proxy communication protocol specifies a way to forward an original address, port, and original transport protocol information end to end. The packet mangling and proxy-to-proxy communication protocol assure network transparency.

  • Patent number: 7286476
    Abstract: An architecture for optimizing network communications that utilizes a device positioned at two edges of a constrained Wide Area Network (WAN) link. The device intercepts outgoing network packets and reroutes them to a proxy application. The proxy application uses multiple, preferably persistent connections with a network accelerator device at the other end of the persistent connection. The proxy applications transmit the intercepted data. Packet mangling may involve spoofing the connection request at each end node; a proxy-to-proxy communication protocol specifies a way to forward an original address, port, and original transport protocol information end to end. The packet mangling and proxy-to-proxy communication protocol assure network layer transparency.
