Apparatus for monitoring movement of a person's eye, e.g., to monitor drowsiness. The system includes a frame that is worn on a person's head, an array of emitters on the frame for directing light towards the person's eye, and an array of sensors on the frame for detecting light from the array of emitters. The sensors detect light that is reflected off of respective portions of the eye or its eyelid, thereby producing output signals indicating when the respective portions of the eye is covered by the eyelid. The emitters project a reference frame towards the eye, and a camera on the frame monitors movement of the eye relative to the reference frame. This movement may be correlated with the signals from the array of sensors and / or with signals from other sensors on the frame to monitor the person's level of drowsiness.

A rotation and / or tilt angle detection device for a ball and socket joint is provided wherein at least one magnet (2), especially a permanent magnet, is arranged in the joint ball (1a), wherein a display device (4) displays the magnetic field of the at least one magnet (2) by means of the magnetooptic effect. An image detection deice (10) detects the information displayed by the display device (4). A data processing unit (50) calculates the relative position of the joint ball (1a) and the ball socket (3) of the ball and socket joint on the basis of the information detected.

A motion detection system is disclosed. The invention comprises a touch panel, a plurality of switching units, a detection unit and a control unit. The touch panel comprises a plurality of metal sensors, each of which in turn is set as a detecting sensor. Each switching unit is electrically connected to a corresponding metal sensor respectively for switching voltage. During a charge stage, the detection unit calculates the discharge time of the detecting sensor and generates a detection result signal. The control unit generates a motion signal according to the detection result signal generated by the detection unit. Based on the capacitive effect and simple hardware architecture, the invention can be employed in option or orientation control by detecting a human hand's movement on the touch panel.

The present invention relates to a signal measurement system (100, 200, 300) for measuring a signal, the system comprising a signal detection unit (41) for detecting a raw signal, a signal processing unit (42) and a signal cable (10) electrically connecting the signal detection unit (41) with the signal processing unit (42). The signal cable (10) comprises a signal conductor (1, 2) for electrically conducting a first signal from the signal detection unit (41) to the signal processing unit (42), which first signal comprises at least the raw signal, a reference conductor (11, 12) for detecting and electrically conducting to the signal processing unit (42) only a noise signal induced by a movement of the signal cable (10) or by electromagnetic interference. In this way the effect of noise on the signal quality is reduced caused by movement of the signal cable (10) or other sources of noise that induce a noise signal in the signal cable (10), such as electromagnetic interference, while at the same time not increasing the power usage or power loss.

A method for ascertaining a state of drowsiness of a driver of a motor vehicle, movements of at least one eyelid of one eye of the driver being detected, and the state of drowsiness of the driver being determined as a function of the detected movements. It is provided that an instantaneous normal degree of eye opening is determined, that closing movements of the eyelid are monitored based on the normal degree of eye opening, and that the state of drowsiness is determined as a function of the detected closing movements.

A remote control device provided with a means for receiving light from a light-emitting element 21 at a light-receiving element 3 and detecting from a signal thereof a movement amount of a mark 16 on a screen 2a of a display device 2 so as to cause movement of the mark such as a pointer on the screen of the display device in response to a movement amount of a light emission point H of the light-emitting element, wherein the light-receiving element is provided with a semiconductor position detection element, and moreover, is configured to be capable of detecting movement of the light emission point in a horizontal direction and a vertical direction, and causes the mark on the screen of the display device to move due to the signal from the light-receiving element.

A rotating actuator includes a shaft (24) and a mechanical stop device (23) for generating a stop to limit the rotation of the shaft in a direction of rotation. The stop device acts upon the shaft to prevent the shaft from rotating further in the direction of rotation by blocking the shaft using a stop device acting mechanically on the shaft while enabling rotation of the shaft in a direction of rotation counter to the stop with slip in a stop arrangement. The slip is configured such that movement of the shaft in the direction of rotation counter to the stop is detectable. The stop device may include two independently triggered, mechanical stop devices. One stop device acts as a stop for limiting the rotation of the shaft to the right, and the other stop device acts as a stop for limiting the rotation of the shaft to the left.

A system and method for a connected wireless device to hand off from one network to another based on empirical data gathered from real live networks regarding the grade of service available on the network. The invention uses this information in combination with the user's choice of a preferred type of network connection to intelligently manage and conserve device battery life.
