Abstract: A system for the therapeutic treatment of joints comprising a composite material comprising a biodegradable polymer matrix and a plurality of piezoelectric particles adapted to generate local electric charges in response to an external stimulation made by means of ultrasound, said plurality of piezoelectric particles being dispersed in the matrix. The composite material also comprises a plurality of stamina cells dispersed in the biodegradable polymer matrix and a plurality of carbon-based particles. The system also comprises a releasing device, arranged to deposit the composite material in a joint cavity at predetermined areas of the cartilage, and a stimulator device arranged to emit ultrasound at a predetermined frequency, a predetermined intensity and for a predetermined time of application, in such a way that, when the device is located near a joint wherein the composite material has been deposited, said ultrasound stimulate the plurality of piezoelectric particles.

Abstract: An arrangement for detecting a load carried by a carrier intended to be tracked by a real-time locating system comprises: a tag intended to be arranged on the carrier, the tag being configured to generate a wireless signal allowing determination of a position of the tag; and at least one detector configured to detect the load carried by the carrier and to generate a wireless signal indicative of at least one of whether or not a load is carried by the carrier and an amount of load carried by the carrier. The arrangement allows for accurate carrier utilization tracking in a cost-effective manner. A real-time locating system comprising such an arrangement and a method for detecting a load carried by a carrier are also disclosed.

Abstract: An arrangement for monitoring the operation of a machine intended to be tracked by a real-time locating system comprises: a tag intended to be arranged on the machine, the tag being configured to generate a wireless tag signal allowing determination of a position of the tag; and at least one detector intended to be arranged on the machine, the at least one detector being configured to detect at least one characteristic of a magnetic field generated by the machine. Detection of the at least one characteristic is indicative of the machine being operative. The arrangement makes it possible to obtain a detailed understanding of how the machine is used in a cost-effective manner. A real-time locating system comprising such an arrangement and a method for monitoring the operation of a machine are also disclosed.
