Disclosed is a drive unit for a wheelchair and a wheelchair including such. The wheelchair includes a control input and a structural frame with two lateral frame elements, each supporting a drive wheel. The drive unit includes two drive motors within a driveshaft housing, adapted to drive the drive wheels independently based on input via the control input. The drive shaft housing is releasably attached between the two lateral frame elements of the wheelchair and connected to the drive wheels via quick-release couplings. The drive shaft housing is divided into at least two sections, each section housing one of the drive motors and that the at least two sections of the drive shaft housing are telescopically moveable relative to each other for adjusting the width of the drive shaft housing to different wheelchairs having different distances between the lateral frame elements of the structural frame of the wheelchair.

The present invention relates to controlling a removable electric propulsion system for a rolling object. In this method, a signal representative of the torque at a wheel driven by an electric machine of the electric propulsion system is measured (MES). This measurement is compared (COMP), over different time increments, with two thresholds, and the electric machine is controlled according to this comparison. The invention also relates to a propulsion system suited for this method and to a coupled assembly comprising the propulsion system and a rolling object.

A patient support apparatus that is adaptable to multiple modes of transport includes a variable length base and a drive system that includes two independently drivable wheels that are responsive to inputs from a user to steer the patient support apparatus.

A patient support apparatus comprising a support structure, an input device, an actuator, and a controller. The support surface comprises a patient support surface. The input device generates an input signal. The actuator is coupled to the support structure and is configured to perform an operational function and a feedback function, separate from the operational function, to provide feedback to a user. The controller is in communication with the actuator and the input device and is configured to control the actuator to perform the operational function in response to receiving the input signal from the input device, and to control the actuator to perform the feedback function separate from performing the operational function.
