Abstract: Provided is a method (100) comprising providing (102) a nonblood bodily secretion sample having a concentration of an analyte. The analyte is separately detectable in blood. The method also comprises determining (104), independently of any measurement of said concentration, a measure of an absolute amount, in other words a total amount, of the analyte in the nonblood bodily secretion sample. Further provided is a sensing assembly for implementing the method, and a method for determining a correlation between such a measure of an absolute amount of the analyte in a nonblood bodily secretion sample and a blood concentration of the analyte in blood.

Abstract: A system is provided for detecting lung abnormalities in a subject. The system comprises a first sensor, for sensing a first acoustic signal generated by, or applied to, the subject and an arrangement of one or more second sensors for detecting a plurality of second acoustic signals from the lungs of the subject, wherein the second acoustic signals comprise attenuated versions of the first acoustic signal after passing through the lungs of the subject. The system further comprises a processor, wherein the processor is configured to determine a respective signal attenuation between the first acoustic signal and at least a subset of the plurality of second acoustic signals and process the signal attenuations thereby to detect a lung abnormality.

Abstract: In the current diagnostic imaging workflow, transfer of handicapped patients between a hospital bed to a patient support of an imaging system and back is performed manually, which may be physically exhausting for staff and uncomfortable for the patient being transferred. Furthermore, this should be avoided in an autonomous scanning environment. Accordingly, the present application proposes an approach for enabling patient pain detection and reduction when using a patient transfer device configured to transfer a patient between a first and a second patient support.

Abstract: A field driven electroactive polymer actuator which is actuated using an actuation drive having a profiled portion having a start voltage and an end voltage and a duration of at least 25 ms followed by a steady state drive portion based on a steady state voltage. The profiled portion comprises a voltage curve or a set of voltage points which define a first voltage slope at the beginning of the profiled portion which is steeper than a linear ramp between the start voltage and the end voltage, and a second voltage slope at the end of the profiled portion which is shallower than a linear ramp between the start voltage and the end voltage.

Abstract: An actuator device has an electroactive polymer actuator (35) and an integrated piezoelectric transformer (30) whose primary side (32) and secondary side (34) are formed from different electroactive polymer materials. At least the secondary side (34) of the transformer shares a piezoelectric electroactive polymer layer (36) with the electroactive polymer actuator, so that lower external voltages can be applied to the device.

Abstract: There is provided a cutting assembly for use in a hair cutting device. The cutting assembly includes a cutting element having a first end and a second end, the cutting element comprising an optical waveguide for receiving light from at least one light source. The cutting assembly includes a first light guiding element configured to guide light from the at least one light source into the first end of the cutting element, and a second light guiding element configured to guide light from the at least one light source into the second end of the cutting element. Each of the light guiding elements comprises a taper transition section in which a diameter of the light guiding element reduces from a first diameter to a second diameter. A hair cutting device comprising a cutting assembly is also disclosed.

Abstract: A flow control device comprises a laminate structure of an electroactive material layer and a non-actuatable layer. An array of orifices is formed in one of the layers wherein the orifices are open in one of the rest state and actuated state and the orifices are closed in the other of the rest state and actuated state. Actuation of the electroactive material layer causes orifices to open and close so that flow control function may be implemented.
