  • Publication number: 20160139853
    Abstract: Dynamic sharing of RAM in a software-defined communication system includes storing program code in a flash memory, categorizing parts of the code into groups of transmit categories according to when a part of the code needs to be copied into a section of a RAM and then executed during a first state of a TX state machine and according to how another part of the code can be later fit into the same section and then executed during a second state. Similarly, parts of the code are categorized into groups of receive categories according to when a part of the code needs to be copied into a section of RAM and then executed during a first state of a RX state machine and according to how another part of the code can be later fit into that section and then executed during a second state of the RX state machine, to reduce the amount of RAM without sacrificing speed performance.

  • Patent number: 9336361
    Abstract: A system and method for issuing a license for a device through a license server is provided. A server receives identification information for a device that communicates to the server if a first license binding identity and/or a first display identity has changed. A previous license for the device is revoked and a previous license credit is returned to a user's credit pool if the first license binding identity and/or the first display identity has changed. A license request is received, which includes a second license binding identity identifying the device. If the second license binding identity is the same as the first license binding identity, the previous license for the device is issued. If the second license binding identity is not the same as the first license binding identity, a new license for the device is issued and a new license credit is deducted from the user's credit pool.

  • Patent number: 9335027
    Abstract: Transparent displays enable many useful applications, including heads-up displays for cars and aircraft as well as displays on eyeglasses and glass windows. Unfortunately, transparent displays made of organic light-emitting diodes are typically expensive and opaque. Heads-up displays often require fixed light sources and have limited viewing angles. And transparent displays that use frequency conversion are typically energy inefficient. Conversely, the present transparent displays operate by scattering visible light from resonant nanoparticles with narrowband scattering cross sections and small absorption cross sections. More specifically, projecting an image onto a transparent screen doped with nanoparticles that selectively scatter light at the image wavelength(s) yields an image on the screen visible to an observer. Because the nanoparticles scatter light at only certain wavelengths, the screen is practically transparent under ambient light.
