Abstract: A door interface system for a vehicle door includes a sensor and a visual indicator. The sensor may be a proximity sensor and may be positioned proximate to the visual indicator such that it will detect an object proximate to the proximity sensor. The visual indicator may convey the position of the sensor and/or a status of the vehicle door. The door interface system is configured to control the vehicle door based at least in part on detecting an object proximate the visual indicator.

Abstract: A thermoregulation interface pack (10) for the treatment of physical injuries and disorders includes a plurality of conduits (12-16) providing separate feed and return through channels (24, 26), are arranged in each conduit in a plurality of spiral shapes (30), each of which provides a fluid path inversion (32). At the fluid path inversion (32) the conduits (12-16) are provided with flow constrictors (50). This shape of the conduits (12-16) provides an array of zones (30) of zero fluid speed which optimises energy transfer between the interface pack (10) and the patient. The interface pack (10) is preferably formed of two layers (60, 62) of material of which the inner or contact layer (62) is made of a more conformable material than the overlying or upper layer (60), causing the contact layer (62) to deform to a greater extent than the upper layer (60), thereby to increase surface contact with the patient.

Abstract: A control system for a thermoregulation assembly includes a fluid manifold assembly (12?) and a control unit (56?). The fluid manifold assembly includes a manifold output (26) for supplying thermoregulation fluid to an interface pack. The manifold assembly is operable to selectively provide thermoregulation fluid into the interface pack in accordance with feed parameters. The control unit (56?) can obtain a desired temperature profile and a conversion algorithm, the conversion algorithm providing a formula for deriving one of more feed parameters for bringing the interface pack to or maintaining the interface pack at a desired temperature dependent upon a characteristic energy transfer rate between a user and the interface pack. The control unit (56?) is operable to calculate one or more feed parameters from the desired temperature profile and the conversion algorithm and to operate the manifold assembly (12?) in accordance with the one or more feed parameters.
