    • A method of determining a measure of a tissue state ( e.g. , glycation end-product or disease state) in an individual. A portion of the tissue of the individual is illuminated with excitation light, then light emitted by the tissue due to fluorescence of a chemical with the tissue responsive to the excitation light is detected. The detected light can be combined with a model relating fluorescence with a measure of tissue state to determine a tissue state. The invention can comprise single wavelength excitation light, scanning of excitation light (illuminating the tissue at a plurality of wavelengths), detection at a single wavelength, scanning of detection wavelengths (detecting emitted light at a plurality of wavelengths), and combinations thereof. The invention also can comprise correction techniques that reduce determination errors due to detection of light other than that from fluorescence of a chemical in the tissue. For example, the reflectance of the tissue can lead to errors if appropriate correction is not employed. The invention can also comprise a variety of models relating fluorescence to a measure of tissue state, including a variety of methods for generating such models. Other biologic information can be used in combination with the fluorescence properties to aid in the determination of a measure of tissue state. The invention also comprises apparatuses suitable for carrying out the method, including appropriate light sources, detectors, and models (for example, implemented on computers) used to relate detected fluorescence and a measure of tissue state.
    • 确定个体中组织状态(例如,糖基化终产物或疾病状态)的量度的方法。 用激发光照射个体组织的一部分,然后检测由组织响应于激发光的化学物质的荧光而由组织发出的光。 检测到的光可以与将荧光与组织状态的测量相关联的模型组合以确定组织状态。 本发明可以包括单波长激发光,激发光的扫描(以多个波长照射组织),单个波长的检测,检测波长的扫描(检测多个波长的发射光)及其组合。 本发明还可以包括校正技术,其减少由于检测除了组织中的化学物质的荧光以外的光的测定误差。 例如,如果不采用适当的校正,组织的反射率可能导致错误。 本发明还可以包括将荧光与组织状态的测量相关联的各种模型,包括用于产生这种模型的各种方法。 其他生物信息可与荧光性质结合使用,有助于测定组织状态。 本发明还包括适于执行该方法的装置,包括用于检测荧光和组织状态测量的适当的光源,检测器和模型(例如,在计算机上实现)。

    • A method for providing interactive information content in an analog cable system having only a one-way communication path from a cable head end to a communication device, such as a set-top box that is associated with a television is disclosed. A set-top box receives a plurality of interactive information content signals on at least one analog channel from the cable head end. In certain embodiments the interactive information content signals are data streams that sent over an analog carrier channel. The set-top box provides a selection screen to the television for display. A user can then use a user-input device, such as, a remote control to make a selection. In general, the user will select a key, such as a directional key and the remote control will provide the selection/directional signal to the set-top box. The set-top box then outputs a new information content signal based the received selection signal without having to transmit to the head end.
    • 公开了一种在仅具有从电缆头端到通信设备的单向通信路径的模拟电缆系统中提供交互式信息内容的方法,例如与电视机相关联的机顶盒。 机顶盒在电缆头端的至少一个模拟通道上接收多个交互式信息内容信号。 在某些实施例中,交互式信息内容信号是通过模拟载波信道发送的数据流。 机顶盒为电视机提供选择屏幕进行显示。 然后,用户可以使用诸如遥控器的用户输入设备进行选择。 通常,用户将选择诸如方向键的键,并且遥控器将向机顶盒提供选择/定向信号。 然后,机顶盒基于接收到的选择信号输出新的信息内容信号,而不必向头端发送。
