Abstract:
An x-ray image sensor (1) with a lead-oxide photoconductor layer (6) positioned between collecting electrodes (3) and a common electrode (2) is provided with a passivation layer (7) which separates the lead-oxide from the metal of the common electrode to counteract degradation of the photoconductor layer due to chemical reactions between then metal of the common electrode and the lead-oxide. A bias layer (8) is provided between the common electrode (2) and the photoconductor layer (6) and a cladding layer (9) is provided between collecting electrodes (3) and the photoconductor layer (6) so as to avoid injection of charges into the photoconductor layer.
Abstract:
System and method for guiding breathing exercises, a method of processing a sensor signal related to breathing and a use thereof. The application describes a system that allows a guided breathing exercise, where the intensity, frequency and duration of exercises can be adapted to the actual performance of the exercising user. This is obtained a sensing unit (1) monitoring throughout the exercise the process of in- and exhalation and bated breath. A controller (3) uses this information to adapt the actual timing of each of these phases to the desired rhythm of the specific exercise. Also the intensity of inhalation and exhalation can be monitored and adjusted. An instruction device (2) instructs the user with the adjusted exercise, preferably by feedback in audible, visual or tactile manner.
Abstract:
The present invention relates to a bed with an integrated sensor unit for a patient. Furthermore the invention relates to a method of providing a bed with a sensor unit for a patient. In order to provide a simple and reliable technique for monitoring patients a bed is suggested, comprising a bedframe (3) with at least a first and a second bedframe section (1, 2), said bedframe sections (1, 2) being connected to each other by means of at least one hinge (4), the bed further comprising a sensor unit (5, 5'), characterized in that the sensor unit (5, 5') is connected with the pivot (9) of the hinge (4), and is adapted to measure the movement of a bedframe section (1, 2) in a direction (21) substantially perpendicular to the rotary axis (22) of the pivot (9).
Abstract:
The invention relates to the area of rehabilitation for patients with motor disabilities, especially for hemiplegic patients. With the present invention a long term, e.g. day and night, patient activity monitoring can be established in a home environment. A core idea of the invention is to evaluate the functional use of a limb by determining the synchronicity of the patient's movements depending on the movement's cyclicity. With this approach a reliable assessment of limb usage can be made based on the daily living activities of the patient. With the present invention the progress of rehabilitation can be monitored and guidance can be provided to therapists and patients about the state of the rehabilitation process. It further makes them aware of a lack of limb usage.
Abstract:
The invention refers to a sensor arrangement comprising at least one capacitance sensor for detecting a pressure and a shear force, wherein the capacitance sensor is integrated into a wearable textile, a method for measuring a shear force and a pressure by such a sensor arrangement, wherein the shear force and pressure is exerted on a skin of a person lying in a bed or sitting in a chair and to combinations and uses of the method. This described textile sensors allow for a simultaneous measurement of shear stress and pressure in anti decubitus textiles. This enhances risk assessment with regard to the development of bedsore ulcer.
