Abstract: A low-power personal epilepsy seizure warning system is disclosed based on the clinical observation that while the brain potentials marking the onset of epilepsy vary from patient to patient, indicative brain potentials in any one patient are highly likely to remain constant. The system includes an implantable monitor to detect brain potentials and recognize the onset of a seizure, and an external warning unit to warn the patient when a seizure is imminent. The monitor is configured to recognize a patient's indicative potentials after preoperative EEG observation, and may include relatively simple analog circuitry to recognize simple forms, or a microprocessor and programmed memory to recognize complex forms utilizing algorithms such as the fast Fourier transform. An external program adjustment unit may also be utilized to increase or decrease the sensitivity of the monitor corresponding to the patient's experience of insufficient or excessive warnings after implantation.

Abstract: Novel methods for the parenteral administration of nutriments to patients, which comprises opening the umbilical vein and introducing an aqueous solution of nutriments into the opened vein, thereby permitting the maintenance of patients who are unable to ingest sufficient foods by the normal oral route.
