  • Patent number: 11971288
    Abstract: A level meter includes light emission segments forming an emission region, a register portion to register a default emission condition and an emission-condition specified value, and a control portion. The control portion controls the light emission so that the emission region spreads in an emission proceeding direction according to an increase in numerical quantity to be expressed. An emission-condition specified value indicates a command to apply a predetermined specified emission condition concerning a subsequent segment positioned on a more upstream side than a foremost segment positioned on a most downstream side in the emission proceeding direction. The control portion allows all the light emission segments forming the emission region to emit light based on the default emission condition, and the control portion allows the foremost segment to emit light based on the default emission condition whereas allowing the subsequent segment to emit light based on the specified emission condition.

  • Patent number: 11965791
    Abstract: An improved prony brake dynamometer capable of measuring the power of a prime mover's rotating shaft connected to a cylinder brake drum rotating around a newly designed dual quad power stator (DQPS), with hydraulic pressure equalizer plate (HPEP), controlled by an electronic load control system with inline cooling system (ELCS), cooled by a 270-degree water distribution manifold (WDM). The improvements of the DQPS and HPEP result in maximizing the pressure applied by the stator over the entire surface area of the rotor drum, thereby maximizing the coefficient of friction at the kinetic point of energy and increasing load capacity over previous models. The addition of the ELCS increases the number of potential settings of hydraulic pressure, resulting in thousands of power settings, as opposed to previous models using manual load control valves. The WDM cools the dynamometer load absorption unit more efficiently than previous models.
