Abstract: A trailer configured to be towed by a towing vehicle and carry one or more goods. The trailer comprises a chassis, a hitch to couple the trailer to a towing vehicle and a receptacle mounted on the chassis and defining a space to hold goods. The trailer comprises at least two wheels. An electric motor is mounted on each wheel, and the electric motors may be independently controlled to each wheel. The trailer comprises: one or more force sensors mounted on the trailer, at least one optical sensor mounted on the trailer, and optionally may include other sensors such as acoustic sensors. The trailer comprises a controller that is configured to process sensor inputs and determine a force on the hitch applied by the towing vehicle, determine an orientation of the towing vehicle and control the electric motor based on the determined force and orientation.

Abstract: A device arranged to be in fluid communication with a patient interface arranged to be in communication with an airway of a patient during respiratory therapy, the device comprising: an inlet for receiving a breathable gas from a respiratory apparatus; an outlet for conveying the breathable gas to the patient interface; a body portion extending between the inlet and the outlet, wherein the body portion includes a trigger port, and one or more sensors, wherein output of the one or more sensors is used to determine a status of the trigger port.

Abstract: A flow generator 21 for a respiratory therapy system configured to deliver a breathable gas flow to a patient comprises a housing 27 comprising an inlet 28 and an outlet 25 and a gas flow path between the inlet 28 and outlet 25. An impeller is mounted within the housing 27 for rotation about an axis, the impeller configured to be rotationally driven by a motor to provide a gas flow along the gas flow path. Various embodiments are disclosed in which the flow generator 21 further comprises a sensor 23 mounted in the housing 27 in the gas flow path and configured to detect a property of the gas flow. The sensor 23 may be mounted in the outlet 25 so as to project into the gas flow path. Flow generator may comprise an axial inlet 28 and a tangential outlet 25. In another embodiment the sensor 23 may be mounted in the inlet 28.

Abstract: A control system for controlling an exoskeleton worn by a user and having one or more actuators associated with various body members of the exoskeleton each corresponding to a body part of the user. The control system comprises a user interface for receiving input data indicative of a desired movement sequence, a memory component for storing pre-programmed movement data indicative of one or more sequential instructions required to effect the movement sequence, each instruction being associated with relative actuator movements for performing the instruction, and an actuator controller for moving the one or more actuators according to the relative actuator movements for each instruction. The control system also comprises a terrain sub-system for adjusting the actuator movements upon detection of a change in terrain slope and a balance control sub-system for periodically adjusting the balance of the exoskeleton during relative movement of the one or more actuators.
