Abstract: The disclosed apparatus may include a capacitive proximity sensor that increases capacitance in response to proximity of an object; a reference capacitor in parallel with the capacitive proximity sensor; a switch that connects and disconnects the capacitive proximity sensor and the reference capacitor; and a capacitance sensing block that generates a capacitance signal based on a capacitance of the reference capacitor when the switch is in a disconnecting state and based on the capacitance of the reference capacitor and a capacitance of the capacitive proximity sensor when the switch is in a connecting state. Various other methods and systems are also disclosed.

Abstract: An electroencephalogram (EEG) utilizing epileptiform activity detection, warning and recording system adapted for use by non-healthcare professionals or healthcare professionals. The system is simple enough for use by untrained personnel and will be self-contained, not requiring technical setup or point of use maintenance. The system includes a small number of passive or active scalp electrodes for capturing the electrical signals in the subject's brain allowing for detection of epileptiform activity. The system will recognize epileptiform activity and will either transmit signals upon detection of epileptiform activity to either a localized warning device or to a cellular or radio receiving device. The system will note epileptiform activity in a recording component and allow for review of the epileptiform data to allow non-clinical and clinical personnel to verify such activity.
