  • Publication number: 20230329932
    Abstract: A patient transport apparatus with a base, a litter comprising a support surface, and a lift mechanism to facilitate arranging the litter at different heights relative to the base between a plurality of lift configurations including a fully-retracted configuration and a fully-extended configuration. The lift mechanism includes an actuator including a cylinder, fluid reservoir, and a pump driven by a motor to direct hydraulic fluid from the fluid reservoir to the cylinder. A sensor outputs a signal indicative of a magnitude of pressure in the cylinder. A user interface with an input control is provided. A controller determines a target parameter for the motor and, in response to user engagement with the input control, drives the motor at the target parameter to effect movement of the litter relative to the base at a predetermined rate irrespective of a weight of a patient supported on the litter.

  • Patent number: 8499578
    Abstract: A water product dispensing system includes a dispenser mounted for selectively releasing a water product, a display provided on the dispenser and a sensor operatively coupled to the dispenser. The dispensing system also includes a sensor for determining a fault condition. In the event that a fault condition exists, the fault condition is presented upon the display only upon operation of the dispensing system. The water product dispensing system also includes a water filter, with the fault condition indicating a need to replace the water filter.
