Abstract: Various embodiments of a device for in-vivo measurements radiopharmaceuticals used for diagnosis and monitoring of radiotherapy are presented. In some embodiments, the present disclosure relates to a device having a cannula that may include a measurement chamber, a radiation detector and a delivery lumen, wherein the device may be used to both deliver material to the patient (e.g., radiotracers used in radiopharmaceuticals) and measure levels and concentrations of radioactive material in, for example, the patient's blood both during and after administration of the radioactive material. In some embodiments, particles emitted by the radioactive material interact with a scintillation material, resulting in the release of light that may be transmitted, via the scintillation material and/or fiber optic material, to an optical detectors or processor for processing.

Abstract: A device for actively controlling combustion instabilities and for decoking uel injectors comprises at least one detector for measuring pressure fluctuations in a combustion or afterburner chamber, means for processing the signal output by the detector and providing, in turn, a control voltage, and at least one piezoelectric device which is disposed in a hydraulic line including a fuel injector for the supply of fuel to the combustion or afterburner chamber and which is responsive to the control voltage to generate pulses in the flow of fuel from the outlet of the fuel injector.

Abstract: A redundant mass flow meter comprises a casing housing a main rotor and an ntermediate rotor which is freely rotatable and is disposed coaxially with a rotationally restricted turbine between the turbine and the casing, a first measuring system for measuring and controlling the position of the turbine relative to the intermediate rotor, and a second measuring system, independent of the first measuring system, for measuring and controlling the position of the intermediate rotor relative to the casing.

Abstract: A urethral probe having a front part and a rear part, and a microwave antenna connected to an external device for generating microwaves. The microwave antenna has its primary active heating part arranged in the urethral probe to be directed onto the prostatic tissues located at least at the level of the bladder neck in the working position.The urethral probe constitutes an essential element of a device for the therapeutic treatment of tissues by thermotherapy, more particularly tissues of the bladder neck of the bladder of a human being.

Abstract: An apparatus for the surgical treatment of tissues by thermal effect, in particular prostate, is disclosed comprising a urethral emitting probe having a front end and a rear end, capable of being inserted in the urethra, provided with microwave antenna located intermediate or in the vicinity of said front end, said microwave antenna being connected to an external microwave generating device, and working at a frequency and at a power effective to heat said tissues to a predetermined temperature for a period of time sufficient to treat said tissues by thermal effect.
