Abstract: This specification discloses a brain electrode device. The brain electrode device includes a set of contact points and a set of sub-circuits. The sub-circuits include sensor ports configured to connect to the contact to the respective ones of the contact points. The device can further include an intelligent multiplexer that aggregates signals from the set of sub-circuits and generates an aggregate signal. The aggregate signal is transmitted to a signal acquisition device.

Abstract: An electrode system is provided for sensing and/or stimulating a brain while reducing risk associated with the sensing and stimulation. The system is scalable to different numbers of contacts to span large areas of the brain. The system includes an electrode array made with a plurality of patches connected together physically and electrically. The array and/or each patch can have its own respective intelligent multiplexer and/or intelligent demultiplexer to aggregate the respective sense and/or stimulate signals, thereby reducing the wire count down to a single wire or wireless link. The array or each patch can have an embedded ground plane, thus minimizing the susceptibility to external EM noise. Moreover, the physical resolution of the array or each patch can be adjusted as needed.

Abstract: A fall detection system includes a plurality of sensors in which at least one of the sensors is coupled to or disposed near a floor. The fall detection system further includes a central monitoring system in signal communication with the plurality of sensors. The central monitoring system is configured to receive a response signal in response to an activation signal being transmitted from at least one of the plurality of sensors, and determine whether the response signal is indicative of a person being arranged in a prone position on the floor.

Abstract: A system and method is presented for reducing skew between the positive and negative components of a differential signal in a high speed communications link. The communications link includes a signal generator producing and transmitting complementary positive and negative signals over separate transmission lines and a receiver receiving the complementary signals. The communication link further includes a skew compensation circuit having a skew detector, a controller, and separate delay and buffer elements for both the positive and negative component of the differential signal. The controller separately controls each of the delay or buffer elements in response to the detected skew between differential signal components.
