The invention concerns a modulator (M) for data transmission between a transponder and a base station, which amplitude modulates and/or phase modulates a received electromagnetic carrier signal as a function of data to be transmitted, having a control input at which a modulation control signal is present, having a rectifier (GL) circuit for rectifying the received electromagnetic carrier signal which has at least one rectifier stage (S1-S3), having at least one switching device (SE) which is controllable through the modulation control signal and whose output side intervenes in at least one rectifier stage of the rectifier circuit, and by means of which a reference voltage can be applied to at least one node (H1-H3) of said rectifier stage. The invention further concerns a transponder with such a modulator and a modulation method for operating such [a modulator].

The present invention relates to acquisition of medical image information of an object. In order to improve operating theatres and allow more effective use of equipment and staff during interventions, a medical X-ray system (10) is provided, comprising a patient support (12), an X-ray image acquisition arrangement (14), a support arrangement (16), and a rail arrangement (18). The image acquisition arrangement (14) acquires imaging information of an object of interest (20) arranged on the patient support (12). The rail arrangement (18) is provided overhead. The support arrangement (16) is movably mounted to the rail arrangement (18), and at least movable along the rail arrangement (18). The image acquisition arrangement (14) is movably mounted to the support arrangement (16) to allow image acquisition of the object (20) from different directions. The rail arrangement (18) is arranged transversely to a longitudinal direction of the patient support.

The testing for the Lyme disease pathogen, (Borrelia bergdorferi (Bb) and all other Lyme Borrelia), is notoriously difficult. Bb is not by nature a blood loving bacteria, and prefers the climate of avascular tissues such as cartilage. The Borrelia Provocation technology disclosed herein proposes to uniquely lure the Lyme Borrelia spirochetes into the blood through a simple procedure of sub-dermal injection of benign tick saliva and co-factors. Lyme Borrelia can then be tested accurately after the provocation injection, utilizing any Lyme Borrelia detection test such as a specific PCR (polymerase chain reaction) test for the most accurate results, as there will be abundantly available DNA present in the blood if there is an existing infection. Treatment is more effective after provocation as well. The provocation protocol taught herein makes accurate, non-invasive, active direct Lyme infection testing possible, and creates a platform for an effective treatment as well.

The invention relates to a broadband ventilation and sound insulation window unit structure and application thereof. The broadband ventilation and sound insulation window unit structure comprises an inner resonant cavity (1), a hollow pipe (2) and a thin-wall shell (3); the outer wall of the hollow pipe (2) is fixedly connected with the inner resonant cavity (1); the outer edge of the inner resonant cavity (1) is sleeved with the thin-wall shell (3); the inner resonant cavity (1) comprises a plurality of layers of hollow cylinders which are arranged on the outer wall of the hollow pipe (2), are stacked up and down and have the same structure and size; the outer edge of the bottom of each layer of hollow cylinder is provided with a horizontal partition plate (11) of an annular structure; and each layer of horizontal partition plate (11) is provided with a circumferential partition plate (4) and a radial partition plate (5) which are used for dividing each layer of resonant cavity into a plurality of resonant spaces. Compared with the prior art, the structure has the advantages that the sound insulation effect is improved, the working frequency band is wide, effective sound absorption can be improved while efficient sound insulation is achieved, and the application range is wide.

Machine to recover a cable, comprising at least one hydraulic pump with variable cubic capacity, provided with a system to adjust the cubic capacity, driven by a servo controller, and at least one hydraulic motor fed by said hydraulic pump by means of at least one pipe to deliver a fluid and at least one pipe to return the fluid.
