Abstract: A control system, computer-readable storage medium and method of preventing occlusion of and minimizing shadows on the driver's face for driver monitoring. The system includes a steering wheel, a plurality of fiberscopes arranged evenly spaced around the steering wheel, and one or more video cameras arranged at remote ends of the plurality of fiberscopes. Distal ends of the fiberscopes emerge to a surface of the steering wheel through holes that are perpendicular to an axis of rotation of the steering wheel. Each of the distal ends of the fiberscopes includes a lens. The system includes a plurality of light sources and an electronic control unit connected to the one or more video cameras and the light sources.

Abstract: Systems and methods for monitoring a user by a plurality of image sensors are disclosed. The system includes a plurality of image sensors that output content descriptive of one or more visual attributes of the user, where each of the image sensors are positioned at a unique angle facing a user. The system also includes one or more processors and one or more non-transitory memory modules communicatively coupled to the one or more processors. The non-transitory memory modules storing machine-readable instructions that, when executed, cause the one or more processors to receive the content from the plurality of image sensors, and assign respective weights to each of the plurality of image sensors based on the content. The respective weights of the plurality of image sensors are actively re-weighted over a period of time. The processors are also caused to merge the content of the plurality of image sensors together.

Abstract: An oscillator having a desired output frequency, comprising a cavity resonator 102 loaded with an anisotropic dielectric material and an oscillator circuit 100 including the cavity resonator 102 as a frequency determining element, the oscillator circuit 100 arranged to operate the cavity resonator 102 at a first frequency in a first mode and at a second frequency in a second mode, the first mode and the second mode each being influenced to a different extent by the thermal coefficient of permittivity of at least one crystal axis of the dielectric material, the oscillator circuit arranged to produce the desired operating frequency from the first frequency and the second frequency. The first frequency and the second frequency differ by an amount corresponding to the desired output frequency.
