  • Patent number: 10691144
    Abstract: A fluid testing system comprises a source that generates electromagnetic waves, a detector that receives the transmitted electromagnetic waves and generates analog signals corresponding to the colours represented in the electromagnetic waves and, a receptacle, having a fluid inlet and an optical inner tube with transparent walls. The receptacle is positioned between the source and the detector to enable the electromagnetic waves to pass through its walls and through a fluid sample in the receptacle. A repository stores a pre-determined range of reference values corresponding to the values of digital signals for fluids of various colours. An analog to digital converter in the system cooperates with the detector to receive the analog signals, converting them into digital signals, wherein the values are compared with the reference values by a comparator. A fluid outlet provides tested fluid. Further, a fuel supply system is disclosed for supplying fuel to a vehicle.

  • Patent number: 10658927
    Abstract: Regulation systems and methods use a first regulator and a tracking second regulator. The first regulator receives a reference voltage and generates a first voltage output based upon the reference voltage, which is coupled as a back-bias voltage to a first load region within the integrated circuit. The first regulator also receives a sampled version of the first voltage output as feedback. A second regulator receives the first sampled voltage output and generates a second voltage output. The second regulator also receives a sampled version of the second voltage output as feedback. During operation, the second voltage output tracks (e.g., by a symmetry ratio) the first voltage output and is coupled as a back-bias voltage to a second load region within the integrated circuit. Further, switched-capacitor operation can be implemented, and clock frequency can be adjusted based upon the first sampled voltage output to reduce power consumption.

  • Patent number: RE48548
    Abstract: In an image sensor, if a pixel for focusing has a structure having a light-shielding layer for performing pupil division, between the micro lens and the photoelectric conversion unit, the pixel may be configured such that the focal position of the micro lens is positioned further on the micro lens side than the light-shielding layer, and the distance from the focal position of the micro lens to the light-shielding layer is greater than 0 and less than nF?, where n is the refractive index at the focal position of the micro lens, F is the aperture value of the micro lens, and ? is the diffraction limit of the micro lens. This enables variation in the pupil intensity distribution of the pixel for focusing due to positional production tolerance of components to be suppressed.
