An omni-directional electric vehicle (11) includes: a body (12) having a chair portion (23); an operation detection unit (13) which detects an operation direction and an operation amount of an operation input; a travel control information generation unit (14) which generates, based on the operation direction and the operation amount, travel control information including (i) a target straight-movement speed for moving the body (12) in a forward/backward direction and (ii) a target rotation speed for rotating the body (12) about a rotation center; and a control unit (15) which drives a movement mechanism of the body (12) according to the travel control information. The travel control information generation unit (14) changes, based on the target straight-movement speed, the rotation center for the target rotation speed from a reference position which is set virtually and fixedly to the body (12) in the forward/backward direction.

A powered wheelchair is operated by sensor-based control pads that include force transducers to produce a variable output signal that is proportional to a varying force applied. The control pad provides an analog-type output that provides a variable speed signal to a controller to operate the wheelchair at a variable speed in both forward/reverse directions and in right or left turning directions.

A standing wheelchair device includes a wheeled base for enabling the device to move on a supporting surface. A harness assembly includes a plurality of braces for attaching to parts of a body of a user of the device, at least some adjacent braces of being connected by joints. A lifting unit mounted on the base, supports a hip joint of the harness assembly, and is configured to raise or lower the hip joint. When the user is attached to the harness assembly and is in a sitting position, raising a height of the hip joint causes the user to assume a standing position. When the when the user is attached to the harness assembly and is in a standing position, lowering the hip joint causes the user to assume a sitting or reclining position.

The present invention relates to a wheelchair, comprising a wheelchair body, a control system, two front wheels and two rear wheels mounted to the front part and rear part of the wheelchair body respectively. The wheelchair further comprises a left and right transmission gear and a front and rear transmission gear mounted to the front part and rear part of the wheelchair body and connected to the two front wheels, the two rear wheels and the control system respectively. The left and right transmission gear is used to drive the two front wheels to rotate left and right and the front and rear transmission gear is used to drive the two rear wheels to move forward and backward and assist left and right rotation. The present invention enables the wheelchair to turn left or right while moving forward or backward on two parallel lines, allowing convenience of use

The invention relates to a floor platform (10, 90) for operating tables (100), said floor platform (10, 90) comprising an interface for securing a patient support unit (110) for supporting a patient, and an omnidirectional electrical drive unit. The drive unit is configured in such a way that the floor platform (10, 90) can be moved and rotated, by the drive unit alone, within a predetermined plane and in any desired direction. Moreover, a control unit (70) for regulating the drive unit is provided, wherein this control unit comprises a manual actuation element (72). Moreover, the control unit has a regulator which, in accordance with the actuation of the actuation element (72), determines trigger signals for the drive unit and sends them to the drive unit, on the basis of which the drive unit moves the floor platform (10, 90). The invention further relates to an operating table (10) with such a floor platform (10, 90).
摘要:
A controller (30) for a motorised vehicle is provided which is arranged to receive control signals from a user input device (32) and the controller (30) is configured to control a motor arrangement (20,22) of the motorised vehicle in dependence on the control signals. The controller (30) comprises an acceleration control unit (60) configured to determine a centripetal force factor corresponding to a centripetal force which is currently acting on said motorised vehicle as a result of the control signals and is configured to calculate an acceleration limit for the motorised vehicle in dependence on the centripetal force factor. The acceleration control unit (60) is configured to apply the acceleration limit by modifying a response of the controller (30) to the control signals, such that the motorised vehicle does not exceed the acceleration limit.

The invention relates to a powered wheelchair for transporting a person, comprising a seat frame for supporting the person, a pair of opposing main wheel assemblies, including a first main wheel assembly and a second main wheel assembly connected to the seat frame, and a third main wheel assembly arranged spaced apart from the pair of opposing main wheel assemblies and connected to said seat frame. The powered wheelchair further comprises a support wheel arrangement for supporting the powered wheelchair, said support wheel arrangement having a main beam and a front support wheel unit capable of being applied to a ground surface. The main beam is rotatably connected to said third main wheel assembly at a third connection point and connected via a guiding mechanism to the first main wheel assembly at a first connection point. The main beam has a first portion adapted to cooperate with said guiding mechanism when said first portion passes through a part of the guiding mechanism upon movement of the main beam relative to the guiding mechanism, to maintain said support wheel arrangement in a supporting position, in which the front support wheel unit is applied to the ground surface.
