Abstract: In a method for initiating a data transfer from an implantable medical device a relay data request is generated at a remote device, the relay data request containing an implant interrogation request representing a request for the implantable medical device to create an interrogation data set. The relay data request is transferred to a patient device, and a communication link between the patient device and the implantable medical device is established to transmit said implant interrogation request to the implantable medical device. An implant interrogation response is transferred from the implantable medical device to the patient device, the implant interrogation response representing a response from the implantable medical device containing said interrogation data set. The implant interrogation response is transferred from the patient device to the remote device.

Abstract: An antenna of an implant programming device that has a telemetry transmit/receive stage, in particular working in the ULP-AMI band, for wireless communication with an electronic medical implant. The antenna is formed as a conductor track on a stiff planar carrier substrate. The surface area of the carrier substrate is much larger than the surface area covered by the conductor track.

Abstract: An air regulator for compressor, in particular for a screw compressor, of the type that has an oil separator device comprising a pre-separator, is provided in a regulator housing containing a valve element which is spring-loaded on one side and can be actuated by means of a piston arrangement. A control device is operatively connected to the air regulator and includes a control piston which, depending on the pre-separator pressure, actuates the valve element of the air regulator in co-operation with a pre-control device in such a way that the regulator immediately and forcibly assumes the closed position upon starting the compressor, while the regulator assumes the open position in an unloaded initial state.
