20120068435 | DRIVE ASSISTANCE DEVICE, WHEELCHAIR AND METHOD FOR DETERMINATION OF THE PHYSICAL EFFICIENCY AND MUSCULAR EFFORT DATA OF A WHEELCHAIR DRIVER - A drive assistance device for a wheelchair includes a drive motor, a running wheel and a sensor device which is adapted to determine a driving force manually induced into the running wheel; and a control unit which is adapted to control the drive motor for driving the running wheel depending on the driving force manually induced by the user into the running wheel. The control unit of the drive assistance device includes a user force analysis operational mode which is adapted to determine data concerning physical efficiency and capacity of the user. These include a maximum force of the user as well as the maximum speed which can be reached with purely manual drive. | 03-22-2012 |
20120067662 | DRIVE ASSISTANCE DEVICE, WHEELCHAIR AND METHOD FOR DETERMINATION OF THE MANUAL DRIVING FORCE OF A WHEELCHAIR DRIVER - A drive assistance device for a wheelchair having a drive motor, a running wheel and a sensor device which is adapted to detect a driving force manually induced into the running wheel. A control unit which is adapted to control the drive motor for driving the running wheel depending on a driving force manually induced by the user into the running wheel has a user force determination operational mode in which the maximum force of the user can be determined. | 03-22-2012 |
20110260417 | STAIR-CLIMBING DEVICE - A stair-climbing device including a support unit, a climbing unit driven by a motor and a control unit for controlling operation of the climbing unit, wherein a detection unit is provided for detecting the current position of the support unit with respect to one or several steps of a stair which includes at least one non-contact sensor, wherein the detection unit provides signals to the control unit, which signals contain information about the current position of the support unit with respect to one or several steps of the stair, and wherein the control unit is adapted to control operation of the climbing unit depending on signals of the detection unit. | 10-27-2011 |
20100062907 | STAIR CLIMBING DEVICE - A stair climbing device, adapted for a wheel chair, including at least one climbing element which is adapted to be moved on a circular path so that it can get in contact with the next step of a stair and lift or lower the stair climbing device on the next step. The stair climbing device includes a drive motor for providing a driving force for moving the at least one climbing element on the circular path, wherein the movement of the at least one climbing element on the circular path is carried out with a non-constant rotational speed. A gear transmission assembly is provided between the drive motor and the at least one climbing element which gear transmission assembly is adapted to cyclically vary the rotational speed of the at least one climbing element with respect to the rotational speed of the drive motor. | 03-11-2010 |
20100036543 | Drive assistance device for a wheel chair and a wheel chair having a drive assistance device - A drive assistance device for a wheel chair having a drive motor, a driving wheel, a sensor means which is designed such that a driving force manually induced into a driving wheel is detected, and a control unit, designed such that the drive motor is controlled to drive the driving wheel in accordance with a drive assistance degree depending on the driving force manually induced into the driving wheel, wherein the control unit comprises an anti-rollback operational mode in which it is adapted to control the drive motor such that an unintended rolling of the driving wheel is avoided. The invention also relates to a wheel chair having such a drive assistance device. | 02-11-2010 |
