Abstract: Various of the disclosed embodiments incorporate wavelength-shifting (WLS) materials to facilitate high data rate communication. Some embodiments employ a waveguide incorporating such WLS materials to receive a wireless signal from a source. The signal may be, e.g., in the optical or ultraviolet ranges, facilitating a ˜10 Gbps data rate. Because the WLS material is sensitive in all directions, the source may be isotropic or wide-angled. The WLS material may be shaped into one or more “bands” that may cover an object, e.g., a head-mounted display. A detector may be coupled with the bands to receive the wavelength-shifted signal and to recover the original signal from the source. The WLS material may be modified to improve the waveguide retention, e.g., by incorporating layers of material having a different reflection coefficient or a Bragg reflector.
Abstract translation: 各种所公开的实施例结合了波长移位（WLS）材料以便于高数据速率通信。 一些实施例采用包含这样的WLS材料的波导从源接收无线信号。 信号可以是例如在光学或紫外范围内，有助于10Gbps的数据速率。 因为WLS材料在所有方向都是敏感的，所以源可以是各向同性的或广角的。 WLS材料可以被成形为可以覆盖物体的一个或多个“带”，例如头戴式显示器。 检测器可以与频带耦合以接收波长移位的信号并从源恢复原始信号。 可以修改WLS材料以改善波导保持，例如通过引入具有不同反射系数的材料层或布拉格反射器。

Abstract: In one embodiment, an apparatus includes a wavelength-shifting element configured to receive an input-light signal. The wavelength-shifting element includes a wavelength-shifting material configured to absorb at least a portion of the received input-light signal and produce an emitted-light signal from the absorbed portion of the received input-light signal. The apparatus also includes an optical-concentrating element configured to receive at least a portion of the emitted-light signal and concentrate the received portion of the emitted-light signal onto a photodetector. The apparatus further includes the photodetector configured to receive the concentrated portion of the emitted-light signal and produce an electrical current corresponding to the concentrated portion of the emitted-light signal.

Abstract: A brain computer interface system interprets an individual's neural signals to predict specific phonemes, words, or sentences, thereby enabling the individual to communicate with others through unspoken methods. Specifically, a brain computer interface system captures neural signals from an individual at mesoscopic resolutions using optical neuroimaging techniques. The system applies the captured neural signals to multiple predictive models that have been trained on neural signals captured from previous individuals. The predictive models output predictions as to a phoneme or word that corresponds to the captured neural signals. Therefore, the individual can communicate through the brain computer interface system by only providing neural signals without using verbal, expressive, or physical means.

Abstract: In one embodiment, a method includes receiving an image on a computing device. The computing device may further execute a classification algorithm to determine whether a target feature is present in the received image. As an example, the classification algorithm may determine whether a building is depicted in the received image. In response to determining that a target feature is present, the method further includes using a segmentation algorithm to segment the received image for the target feature. Based on a determined footprint size of the target feature, a distribution of statistical information over the target feature in the image can be calculated.

Abstract: In one embodiment, a method includes receiving an image on a computing device. The computing device may further execute a weakly-supervised classification algorithm to determine whether a target feature is present in the received image. As an example, the weakly-supervised classification algorithm may determine whether a building is depicted in the received image. In response to determining that a target feature is present, the method further includes using a weakly-supervised segmentation algorithm of the convoluted neural network to segment the received image for the target feature. Based on a determined footprint size of the target feature, a distribution of statistical information over the target feature in the image can be calculated.

Abstract: In one embodiment, an apparatus includes a photoluminescent wavelength-shifting material configured to receive an input-light data signal comprising a first range of wavelengths, absorb at least a portion of the received input-light data signal, and produce an emitted-light data signal comprising a second range of wavelengths based on an upper-state lifetime of the photoluminescent wavelength-shifting material. The apparatus also includes a focusing element configured to receive at least a portion of the emitted-light data signal, concentrate the received portion of the emitted-light data signal, and produce a concentrated-light data signal. The apparatus further includes a photodetector configured to receive the concentrated-light data signal, and produce an electrical current corresponding to the concentrated-light data signal.
