Abstract: Halo vests and the construction methods thereof are provided. The halo vests are designed in unibody structures to minimize the number of components. A 3D scanner is utilized to scan a subject to obtain parameters for a modeling program, which help to construct an optimized halo vest for the subject by printing rather than assembling manually. The subject can easily put on the halo vest without miscellaneous steps.

Abstract: A long-range wireless charging enhancement structure for implantable medical devices (IMDs) is disclosed. The abovementioned enhancement structure provides a possibility for long-range charging the IMDs, which maintains the quality of user's lives and also reduces the risks of replacing the batteries through surgeries. The enhancement structure includes an enhancer, which comprises an emitter, a carrier, an IMD, and an enhancement module. The enhancement module is set within the carrier and disposed at the outer surface of user's skin between the emitter and the IMD. The charging signals emitted by the emitter is enhanced by the enhancement module and further transmitted for charging the IMD inside the user's tissue.

Abstract: A method of controlling automatic stop of a surgical drill 1) uses a smart module to receive instantaneous electrical signals of a driving device coupled to the surgical drill; 2) sets the length of a unit time, and sets the average of all instantaneous electrical signals received in a unit time as a reference electrical signal; and 3) compares the instantaneous electrical signal with the reference electrical signal. When the instantaneous electrical signal experiences a step drop with respect to the reference electrical signal, the smart module sends a stop command to the driving device to stop the operation of the driving device.

Abstract: The present invention discloses a physiological signal wireless transmission system which is compatible with a magnetic resonance system. The physiological signal wireless transmission system comprises an implantable sensing device, and a power relay device wirelessly connected to the implantable sensing device. The implantable sensing device comprises a sensing module including at least one sensor, a data transmission module coupled to the sensing module, and a power receiving module coupled to the sensing module and the data transmission module. On the other hand, the power relay device comprising a data transmission antenna wirelessly connected to the data transmission module, a first microprocessor connected to the data transmission antenna, a display module connected to the first microprocessor, a power transmitting antenna wirelessly connected to the power receiving module, and a power emitting module coupled to the power transmitting antenna.

Abstract: Wireless intracranial monitors are provided. The wireless intracranial monitors comprise a main body, a wireless transceiver, a processing module, and a sensing module, in which the sensing module contains a catheter. On the catheter, a pressure sensor is configured to detect deformation of the catheter or a diaphragm connected to the pressure sensor. The detected deformation is then transmitted to the processing module through an in-catheter wire.
