Abstract: A life support and monitoring apparatus with malfunction correction guidance is provided. The life support and monitoring apparatus of the present disclosure identifies the root cause or potential cause of a fault/failure and then prompts an operator to take appropriate steps to assure the continuance of life support and critical physiologic monitoring. When multiple faults/failures exist, the apparatus automatically prioritizes them based on risk to the patient and prompts the operator to do the most appropriate intervention to assure patient safety.

Abstract: Ventilator enables operator to enter into the microprocessor estimate of a patient's individual characteristic, such as weight, which the microprocessor uses to control delivered tidal volume and other parameters to match the patient. The operator can select one of several ventilator operational modes (intube, mask, CPR). Sensors input data to the microprocessor to maintain parameter optimizations and accuracy. Visual/audible alarms and tools activate when one or more parameters exceed or fail to exceed predetermined values for patient's weight. Manual over-ride is available. The ventilator has a quick start capability in which the operator turns on power, selects the automatic operating mode, enters patient's characteristic, selects control option starting automatic ventilation of proper volumes inhalation/exhalation periods, pressure, and oxy-air mixture.

Abstract: A digitally controlled aspirator is provided with a processor that allows the user to select operating conditions including one or more default settings. The processor further includes sensors for sensing operational and environmental conditions and adjusts the operation of the aspirator to reflect the sensed conditions.

Abstract: An apparatus, system and method for maintaining critical medical equipment for stockpile applications are provided. The apparatus, system and method of the present disclosure can be used to monitor and maintain critical medical equipment in a continuous state of readiness. The apparatus includes a storage case which protects a medical device disposed therein and the accessories required for its immediate application while also providing for constant or intermittent charging of the device's internal battery and serial data monitoring of the primary systems. The system and method also incorporate design features in the medical device which enable performance testing via a remote interface while the device is secured within the storage case.

Abstract: A ventilator circuit is provided for use with a ventilator and a low pressure low flow oxygen source to provide a hyper-oxygenated mixture of air and oxygen at the onset of inspiration. The ventilator circuit achieves this result by using its inspiratory limb to store oxygen between breaths. As a result, the oxygen content of dead space gas is increased before delivery to the distal alveoli of the patient. Accordingly, the ventilator circuit achieves an efficient use of available oxygen and requires less oxygen to a desired oxyhemoglobin percentage at the patient.

Abstract: A portable critical care medical ventilator with autonomous control of oxygenation is provided. The system and method provide for significantly reducing the O2 required to maintain an adequate O2 concentration and as a result delivery of O2 to the body's tissues and does not require the clinician to enter initial values.

Abstract: A dental drill system for use in preparing an osteotomy of a predetermined depth and diameter sized to receive a dental implant therein is disclosed. The drill system comprises at least one elongate depth drill of a first diameter adapted to drill the osteotomy opening to the predetermined depth, and at least one elongate width increasing drill of a second greater diameter adapted to size the diameter of the osteotomy opening to the predetermined diameter. The invention also teaches a method of using the dental drill system to form the osteotomy opening, the method comprising the steps of using a starter drill to define at least a portion of the osteotomy opening, using at least one elongate depth drill of a first diameter to drill the osteotomy opening to the predetermined depth, and using at least one elongate width increasing drill of a second greater diameter greater than the first diameter to increase the diameter of the osteotomy opening to the predetermined diameter.

Abstract: The device mounted at the end of an operating arm comprises one or more suckers for supporting objects, for example refractory bricks for the brick-lining of a metallurgical converter, means for linear and angular displacement of the suckers, sensors for monitoring and controlling automatically the means of displacement in order to grip and position the objects in a predetermined location, after immobilization of the operating arm. The suckers are provided on a sucker-carrying plate which in its turn is supported by a pair of blocks which can slide in transverse slide bars of a carriage which comprises a pair of longitudinal slide bars, perpendicular to the transverse slide bars and housed in sliding fashion in a central support attached to the end of the operating arm with a degree of angular freedom and a degree of linear freedom orthogonal to the axes of the longitudinal and transverse slide bars.

Abstract: The spacecraft system has automatic fault detection and autonomous reconfiguration of redundant hardware and software to correct that fault without ground station intervention. The spacecraft has redundant processors, sensors, control systems and buses. When a unit is believed to have failed as detected by the satellite processor unit, it switches to a backup unit. If the symptom persists after the unit is switched, the processor unit switches to a different bus. If the fault still exists, a new processor unit is switched in and the entire checking and switching repeats.
