Abstract: A thermographic diagnostic device which places a visual mark directly on the skin to indicate localized areas exhibiting skin temperatures a predetermined amount above the temperature of the surrounding areas. A hand held probe with a temperature responsive sensing element and marking instrument at one end is placed in contact with the skin and moved across the body along a desired path. The marking instrument, preferably a pen, is actuated by a control unit when the temperature measured by the sensing element exceeds a preselected temperature relative to surrounding body areas, and a mark is placed on the skin. By moving the probe across the skin in a series of parallel paths, a pattern is placed on the skin corresponding to the localized area of excessive temperature differential.

Abstract: A system which is capable of allowing an attending physician to continuously monitor the electrocardiogram (ECG) signals produced by a cardiac patient. The signals, generated by the patient, are first recorded in real time over a predetermined time period established by the physician. At the conclusion of the predetermined time period a monitoring station is automatically alerted by telephone and commences receiving the patient's real time ECG signals directly. The recorded ECG signals are then transmitted in a compressed time fashion to the monitoring station simultaneously with the real time ECG signals. The monitoring station receives the compressed time and the real time transmitted signals and following analysis thereof transmits a report of selected portions of the ECG to the physician.

Abstract: Storage batteries and/or aggregates thereof are constructed to provide a high impact absorbency, so that their mass will serve a dual function: storing electricity and absorbing collision impacts.The collision protection for humans also involves two separate functions: impact absorption and gradual deceleration. The former is achieved by adding highly shock absorbent closed cell foamed metal plates to the battery aggregate, the second by spacing these in such a way that the impact absorption occurs gradually, so that the deceleration at no point exceeds that of 7 times gravity acceleration. To this end the battery aggregate is designed so that the shock energy absorption occurs in many centers or zones of the battery aggregate, thus providing a safe deceleration curve over a distance equal to the distance from leading side to trailing side of the battery aggregates as installed.
