  • Patent number: 11139666
    Abstract: Energy harvesting and propulsion assistance techniques for a patient support apparatus are provided. The patient support apparatus comprises a base, a patient support surface supported by the base, and a powered device (e.g., propulsion device). An energy harvest and release system includes a harvesting device for harvesting energy, a storage device for storing and releasing the harvested energy, and a controller coupled to the harvesting device, the storage device, and the powered device. The controller is automated to selectively instruct the harvesting device to harvest energy and to selectively instruct release of the harvested energy from the storage device for consumption by the powered device (e.g., to assist in movement of the patient support apparatus).

  • Patent number: 11096850
    Abstract: A patient support apparatus comprising a patient support deck, a touchscreen, and a controller. The patient support deck comprises a patient support surface. The touchscreen comprises a screen, an input surface arranged adjacent to the screen, and a touch sensor configured to generate an electric field within an envelope defined adjacent to the input surface to sense conductive objects interacting with the electric field. The touch sensor is operable at a first sensitivity level to detect conductive objects approaching the input surface, and a second sensitivity level to detect conductive objects engaging the input surface. The controller is in communication with the touchscreen to operate the touch sensor at the first sensitivity level during an absence of conductive objects interacting with the electric field, and to operate the touch sensor at the second sensitivity level in response to conductive objects interacting with the electric field within the envelope.

  • Publication number: 20210186783
    Abstract: Systems, methods and techniques for operating a patient support apparatus are disclosed. The patient support apparatus includes a support structure including a base and a patient support surface to support a patient. The patient support apparatus also includes an actuator coupled to the support structure and operable to move the patient support surface. The actuator is configured to receive an applied voltage and an applied electrical current, and to produce an output power, where the applied electrical current varies based on different loads applied to the actuator. A controller is coupled to the actuator to determine a desired output power of the actuator and to control the actuator such that the output power produced by the actuator is controlled relative to the desired output power by modifying the applied voltage to compensate for the different loads being applied to the actuator.
