Publication number: 20240139045Abstract: A patient transport apparatus with a support structure having a base, a support frame, and a patient support deck defining a support surface. An inertial sensor is coupled to the support structure and generates a signal representing a change in velocity of the support structure. A controller in communication with the inertial sensor has a processor and a non-transitory storage medium having stored thereon a program that monitors the signal generated by the inertial sensor for changes relative to a predetermined threshold. In response to an event in which the signal exceeds the predetermined threshold, the program is further configured to: generate a waveform based on the signal received from the inertial sensor; store the waveform at an overwritable address in the non-transitory storage medium; and generate an entry in an event log stored in the non-transitory storage medium, the entry comprising one or more parameters associated with the waveform.Type: ApplicationFiled: December 21, 2023Publication date: May 2, 2024Applicant: Stryker CorporationInventors: Neeraj Singla, Aaron Douglas Furman, Bhavin Rajeshkumar Kapadia, Brandon David Naber, Thomas Alan Puvogel

Patent number: 11684526Abstract: Patient support apparatuses, such as beds, cots, stretchers, recliners, or the like, include control systems with one or more image, radar, and/or laser sensors to detect objects and determine if a likelihood of collision exists. If so, the control system controls the speed and steering of the patient support apparatus in order to reduce the likelihood of collision. The control system may be adapted to autonomously drive the patient support apparatus, to transmit a message to a remote device indicating whether it is occupied by a patient or not, and/or to transmit its route to the remote device. The remote device may determine an estimate of a time of arrival of the patient support apparatus at a particular destination and/or determine a distance of the patient support apparatus from the particular destination.Type: GrantFiled: June 23, 2021Date of Patent: June 27, 2023Assignee: Stryker CorporationInventors: Michael Joseph Hayes, Krishna Sandeep Bhimavarapu, Daniel Vincent Brosnan, Aaron Douglas Furman, Jonathan David Campbell, Thomas Alan Puvogel, James K.

Systems and techniques for evaluating performance of actuator systems of a patient support apparatus
Patent number: 11607356Abstract: A patient support apparatus comprises a support structure comprising a base and a patient support surface to support a patient. An actuator system facilitates movement of the patient support surface relative to a floor surface. One or more sensors are responsive to changes in position of the patient support surface caused by the actuator system. A controller is operably coupled to the one or more sensors and the actuator system. The controller is configured to operate the actuator system to move the patient support surface and to monitor the movement of the patient support surface by sensing positions of the patient support surface over time. The controller is further configured to identify a frictional load event on the actuator system during movement in a present cycle and associate the frictional load event with a sensed position of the patient support surface in the present cycle.Type: GrantFiled: July 27, 2021Date of Patent: March 21, 2023Assignee: Stryker CorporationInventors: Joshua Alan Mansfield, Thomas Alan Puvogel, Michael Hayes -
Patent number: 11491062Abstract: A strain gauge assembly includes a member and a strain gauge supported by the member spaced.

Patent number: 10603234Abstract: A patient support apparatus includes a frame, wheels, a patient support surface, a motor, a power assist control, a sensor, and a controller. The power assist control detects a force applied to it. The sensor detects an angular orientation of the patient support apparatus with respect to a generally horizontal plane. The controller drives the motor at different levels for a particular force applied to the power assist control depending upon the angular orientation sensed by the sensor. The controller may control the motors such that the patient support apparatus accelerates at substantially the same rate, regardless of the angle of the patient support apparatus. The controller may also limit the driving of the motor to less than a maximum value based upon the angular orientation of the patient support apparatus.Type: GrantFiled: March 28, 2017Date of Patent: March 31, 2020Assignee: Stryker CorporationInventors: Thomas Alan Puvogel, Joshua A.
