Abstract: Disclosed is a skull endosseous implant adapted to be implanted in the subject's skull to provide an access channel. A variety of sensor means may be installed in the access channel for monitoring the intracranial status of the subject. The present invention further provides a kit containing the skull endosseous implant.

Abstract: A rehabilitation apparatus is disclosed. The rehabilitation apparatus includes a supporting housing, a rotary housing, an actuator, a control unit, and a torque detector. The rotary housing is slidably mounted to the supporting housing to hold a body segment. The actuator has a driving shaft to rotate the rotary housing. The control unit is electrically connected to the actuator to control the actuation of the actuator. The torque detector is electrically connected to the control unit, thereby detecting a torque exerted on the driving shaft, and transmitting a torque signal to the control unit.

Abstract: A sensor device that detects Laplacian electroencephalogram (LEEG) signals includes a signal acquisition module placed on a scalp of a subject to acquire brain signals. A signal processor is coupled or connected to the signal acquisition module to perform a Laplacian operation on the signals acquired by the signal acquisition module such that the noise signal is reduced to yield an analog LEEG signal with a high signal-to-noise (S/N) ratio.
