  • Patent number: 10260933
    Abstract: A person support apparatus, such as a bed, stretcher, recliner, cot, or the like, includes a frame, a plurality of load cells, a support surface supported by the load cells, a detection circuit, and a controller. The controller determines if any of the load cells are in an error state based upon information from the detection circuit. If the load cells include memory having calibration data stored therein, the controller communicates with the memory and uses the calibration data to determine an amount of weight supported on the surface. The detection circuit may include one or more Wheatstone bridges wherein the controller monitors voltages between midpoints of the Wheatstone bridges. The load cells may include an activation lead that is monitored by the detection circuit and a sensor lead that is used by the controller to determine an amount of weight supported on the patient support apparatus.

  • Publication number: 20190083337
    Abstract: A patient support apparatus comprising a base movable about a floor surface and a deck comprising sections movable between deck configurations including an egress deck configuration. An articulation system coupled to the deck moves the sections. A lift mechanism moves the deck relative to the base between lift configurations including an egress lift configuration. An egress input is arranged for actuation by a user. A bed detection system monitors data associated with the patient support apparatus and communicates with a remote station. A controller interrupts communication of the bed detection system with the remote station, drives the articulation system to move the sections to the egress deck configuration, and drives the lift mechanism to move the support frame to the egress lift configuration in response to actuation of the egress input.

  • Publication number: 20190083124
    Abstract: Systems (10) and methods (12) of controlling an ultrasonic surgical tool (20) with a console (22) are provided. A first drive signal (40) is applied to the ultrasonic surgical tool (20). A characteristic of a harmonic signal (44) resulting from application of the first drive signal (40) to the ultrasonic surgical tool (20) is acquired. A cancellation signal (70) is generated based on the characteristic of the harmonic signal (44). The first drive signal (40) and the cancellation signal (70) are combined to produce a second drive signal (80) that is sinusoidal. The second drive signal (80) is applied to the ultrasonic surgical tool (20) such that presence of the harmonic signal (44) resulting from application of the second drive signal (80) is reduced relative to presence of the harmonic signal (44) resulting from application of the first drive signal (40).

  • Patent number: 10231649
    Abstract: Patient support apparatuses include a frame, support surface, and a controller. The controller provides notification to a user of a service event relating to the patient support apparatus. The controller limits functionality of a component of the patient support apparatus based upon a severity of the service event. The controller may also, or alternatively, detect when a control is activated by a user and, in response to such activation, determine whether the patient support apparatus has been marked for use or marked for servicing. If marked for use, the controller responds in a first manner, and if marked for service, the controller responds in a different manner. In other embodiments, a method is provided for determining an order in which multiple patient support apparatuses should be service. In still other embodiments, the patient support apparatus automatically changes to an unusable configuration when in need of high priority service.
