Abstract: A patient monitoring system (1) is provided with at least one body sensor (2a) for measuring a physiological parameter, as well as with a body signal processing unit (3) connected downstream from the former and/or a therapy device (2) designed to act on the patient (P), and a mobile radiotelephone end unit (7) operable in a cellular mobile radiotelephone network (1B) for transmitting data from the body signal processing unit or the therapy device to a central monitoring station (1C) and/or from the central monitoring station to the therapy device. A base station coordinate memory unit (13; 13′) and a locator unit (12, 12.1′ through 12.3′) connected to the former serves for the rough determination of the location of the patient based on location information obtained from the current base station connection of the mobile radiotelephone end unit in the mobile radiotelephone network.

Abstract: An implantable cardiac pacemaker (1) comprising a control device (2) including a position detector connected to a movement sensor, wherein the position detector has a classification device (23) for recognizing short movements. Preferably the position detector has a memory device (25).

Abstract: A rate-adaptive pacemaker includes an impedance measuring device for measuring a waveform over time of the intracardial impedance over at least a predetermined portion of one cardiac cycle. An impedance processing device obtains an impedance value from the waveform. A rate determining device is connected downstream of the impedance processing device, and controlled by a sequence controller, determines the adaptive stimulation rate (HR) using the impedance value. The impedance processing device has an integrator stage for determining the time integral of the impedance waveform over the predetermined portion of the cardiac cycle as the primary impedance value.

Abstract: A brush holder mechanism for electric motors, especially the fractional horsepower commutator-equipped motors of workshop power tools. In order to prevent failure of the tool due to jamming of the carbon brushes in their holders, the brush holder according to the invention provides that the brush holder casing in which the carbon brush moves has smooth, flat and uninterrupted interior surfaces and the casing is constructed of a single piece of metal or a single piece of metal on which a continuous cover plate is attached. The integral construction of the casing insures that the casing is not deformed during manufacture or assembly, in particular by the bending of parts of the casing into fastening tabs and the like. In the brush holder according to the invention, the fastening means are integral with the cover plate or the casing. In other embodiments, the casing is held in a receiver by clamps and screws.
