Abstract: A propeller blade comprising a de-icing system is described, wherein the propeller blade comprises a blade body 1 comprising a carbon fiber fabric skin, a leading edge 11, a trailing edge 12, a hub end 9 and a tip end 10. The blade body 1 comprises a resistive wire 4 that extends along the leading edge 11 to a conductive glue 6. The resistive wire 11, the conductive glue 6 and the carbon fiber fabric in the skin of the blade body 1 form a conductive path for an electrical current. A propeller comprising a plurality of the propeller blades, a UAV comprising one or more of the propellers are also described.

Abstract: Disclosed is a computer-implemented method of analyzing the setup of an array of acceleration sensors on an anatomical body part of a patient encompasses acquisition of acceleration data using a cranial headset having acceleration sensors and determining an appropriate contact of the acceleration sensor to the patient's head, detecting, marking, filtering out, or removing different kinds of noise as well as acceleration signals which are considered to be due to gross patient movement. This is done to determine whether the setup of the headset on the patient's head is good enough to generate measurement signals of acceptable quality. If this is the case, the headset is subsequently used to acquire continuous datasets of acceleration data which is then evaluated to determine the patient's physiological status.

Abstract: A power system enclosure is provided. The power system enclosure includes a housing accommodating a power source. The power system enclosure further includes an enclosure inlet connected to the housing to allow entry of an intake fluid into the housing. An enclosure exhaust is connected to the housing to route fluid from the housing. Further, a relief damper is disposed in the enclosure exhaust. At least a portion of the relief damper is configured to open when a pressure within the housing exceeds a predetermined threshold value.

Abstract: A modem for communicating application data over a voice channel comprises an adaptive modulator, a mixer, and a vocoder. The adaptive modulator modulates application data as a function of a source application of the application data and feedback information of the voice channel. The modulated data is inputted to the mixer. The vocoder processes the mixed data for transmission through the voice channel.

Abstract: The invention relates to a photovoltaic system with a plastic support and a photovoltaic module for installation on roofs. The plastic support (1) may be mounted directly to a roof substructure, so that an additional roof covering can be dispensed with. The photovoltaic modules may be fixed on the plastic support (1) without screwing.

Abstract: The electrode comprises a) a layer (5) which conducts electricity for the supply or the collection of an electrical current traversing the electrode, and b) a consumable electrochemical interface layer (7). According to the invention, it comprises, in addition, an intermediate layer (6) made of a chemically inert and electrically resistant material. This layer can consist of a dispersion of fine particles of carbon in a polymer binder. Application in the preparation of electrodes with increased electrochemical capacity, for an ionophoresis device for the transdermal administration of drugs or a device for the electrocicatrization of wounds.
