  • Patent number: 11466842
    Abstract: A light shaping apparatus consisting of two or more components which may be die cast from aluminum, magnesium, or similar materials that are meant to be attached to existing LED venue lighting fixtures. These components are designed so that they can be rotated and adjusted on the fixture circumference/edge. A semi-circular snoot flares out slightly from the outer edge of the fixture to reflect light that would normally be absorbed by a visor. The snoot may include a reflector on its inside surface. The snoot has connection points that mate with the fixture. The snoot also has connection points which allow it to be connected to a semi-circular bowl spaded brow adapted for cutting into the beam of light and block some of light emitted from the fixture. The brow is preferably one piece and has multiple sets of thin shear lines cast into it such that the length of the brow can be modified by breaking off material along the shear lines.

  • Publication number: 20220219676
    Abstract: A vehicle control system for reducing turn radius of a vehicle may include a controller and a torque control module operably coupled to the controller and to front wheels of a front axle of the vehicle and rear wheels of a rear axle of the vehicle. The controller may also be operably coupled to components and/or sensors of the vehicle to receive information including vehicle wheel speed and steering wheel angle. The torque control module may be operable, responsive to control by the controller, to apply a negative torque to an inside rear wheel during a turn and apply a positive torque to the front axle during the turn to compensate for the negative torque applied to the inside rear wheel to reduce the turn radius based on the steering wheel angle and the vehicle speed.

  • Patent number: 9209827
    Abstract: An integrated circuit includes a component calculator configured to compute at least one component value of a highly programmable analog-to-digital converter (ADC) from at least one application parameter, and a mapping module configured to map the component value to a corresponding register setting of the ADC based on at least one process parameter, wherein the integrated circuit produces digital control signals capable of programming the ADC. In a specific embodiment, the component calculator uses an algebraic function of a normalized representation of the application parameter to approximately evaluate at least one normalized ADC coefficient. The component value is further calculated by decimalizing the normalized ADC coefficient. In another specific embodiment, the component calculator uses an algebraic function of the application parameter to calculate the component value.
