Abstract:
The invention relates to a computer tomograph provided with a charge-integrating read amplifier having a plurality of gain factors for a data acquisition system as well as a control circuit for the gain factor. In order to avoid noise in addition to the shot noise in computer tomographs of this kind and also to avoid degrading of the DQE (Detection Quantum Efficiency), according to the invention it is proposed that the control circuit automatically selects the gain factor in dependence on the expected integrated input signal of the next frame, the expectation being based on the maximum possible relative variation of the integrated input signal between two successive frames.
Abstract:
The present invention relates to a mobile electronic device for acquisition of medical data of a user. The mobile electronic device is preferably implemented as an electronic otoscope and serves to acquire otoscope images indicating for example ear infections and tonsillitis. The mobile electronic device is adapted to transmit acquired medical data to a service center by making use of conventional communication devices. In response to a request, the user receives appropriate medical assistance from the service center. Since the mobile electronic device has implemented a billing module, the user not necessarily has to register with the service center. A huge variety of different payment models applies allowing for a universal usage of the mobile electronic device for various scenarios related to child care or medical assistance during travel and holiday. The mobile electronic device is ideally suited for universal medical precaution and medical assistance.
Abstract:
The present invention relates to a device and method for measuring a user's heart rate. In order to provide a reliable and inexpensive heart rate measuring technique, a device (1) and a method for measuring a user's heart rate is suggested in which the relative movement between a heart rate sensor (2) and the user is detected to generate a correction signal for removing motion artifacts caused by a user' s movement.
Abstract:
The invention relates to a method for automatic customization of a service to a user by a remote host (32') by means of a telematic communication (40), said remote host comprising storage means (47) for storing a background information about the user, said method comprising the steps of initiating a trigger information (39) at a user's site upon an occurrence of an event corresponding to a need of the user, acquiring a context information (36) about the user at the user's site, combining the trigger information (39) with the context information (36) in a specific message, sending the specific message to the remote host by means of the telematic communication, receiving the specific message by the remote host, processing of said trigger information by the remote host in combination with the background information (47) according to a prestored user identification (45), processing said context information (43) by the remote host, putting forward a service offer to the user based on a combination of said trigger information (41), said background information (47) and said context information (43).
Abstract:
A method for manufacturing method for manufacturing a wearable monitoring system, said method comprising a step of providing a fabric-based elastic belt for housing of electrodes, the electrodes being provided by molding of an electrode material through the elastic belt. The fact that the necessary electrodes are integrated in the belt of the garment contributes to the user-friendliness of such a monitoring system. Furthermore such a system is washable which further contributes to the comfort of the patient.
Abstract:
An X-ray detector includes an array of X-ray sensitive sensors, each sensor including a conversion element which converts incident X-rays into electric charge pulses. The X-ray detector also includes an evaluation unit which is electrically connected to the conversion element in order to receive and evaluate the electric charge pulses. In order to form an X-ray detector which exhibits a high degree of linearity over a large dynamic range in conjunction with a higher maximum count rate and in order to avoid falsification of the calculated image by multiple counting of X-ray quanta, the evaluation unit includes a current/frequency converter as well as an electronic counter which is electrically connected thereto. The electric charge pulses from the conversion element are applied to the input of the current/frequency converter whose output pulses are applied to the electronic counter.
