A patient support (10) may, among other things, support a person in a laying-down or a seated position. A mobile lift (150) may assist a person with the process of moving from a seated or laying-down position to a standing position, or moving from one type of patient support to another (e.g. from a bed to a wheelchair or vice versa). A docking apparatus (56,58,90) may secure the position of the mobile lift (150) relative to the patient support (10). The docking apparatus (56,58,90) may include an electrical connection between the mobile lift (150) and the patient support (10). The docking apparatus (56,58,90) may permit control of the mobile lift (150) by the patient support (10), and/or permit control of the patient support (10) by the mobile lift (150).
