Show moreThis invention relates a control strategy for a hybrid electric vehicle having an electric motor, a battery and an internal combustion engine. The control strategy improves fuel economy and reduces emissions while providing sufficient acceleration over a varying set of driving conditions through an adaptive control unit with an artificial neural network. The artificial neural network is trained on a pre-processed training set based on the highest fuel economies of multiple control strategies and multiple driving profiles. Training the artificial neural network includes a training algorithm and a learning algorithm. The invention also includes a method of operating a hybrid electric vehicle with an adaptive control strategy using an artificial neural network.

Show moreA collapsible, transportable personnel isolation apparatus or device is used to isolate a patient in a controlled environment and to protect the patient against biological or chemical hazards during transport of the patient. The collapsible apparatus has a flexible containment wall which is expandable from a collapsed, stored state to an expanded state to receive the patient. At least a portion of the containment wall is clear to allow observation of the patient within an interior region of the device. An air filtration system is provided for filtering air between the airtight interior region and the ambient atmosphere. Preferably, the apparatus has various ports therein, such as glove ports, pass through ports, access ports for cardiac leads, infusion line ports, and ventilation ports. Preferably, an air filtration device provides a flow rate of 4 to 6 cfm to prevent an undesirable build-up of carbon dioxide and provides a predetermined air pressure within the interior regions. In one form, the containment device is a clam shell litter type for transport of a prone patient and in another form the device is a jacket type with a hood defining an air impermeable chamber for an ambulatory patient who carries an ambulatory air filtration device for supplying and filtering the air impermeable chamber.

Show moreA data transmission and receiving network includes a plurality of nodal apparatus for sending and receiving digital data in variable length data slots. The nodal apparatus includes a storage device for maintaining a conflict resolution queue representative of nodal apparatus sending simultaneous requests for transmission causing a collision during a control minislot. The nodal apparatus also includes a transmission queue stored in the storage device. The transmission queue is indicative of nodal apparatus that have successfully transmitted during a minislot and are thus queued for transmission of data in data slots. The apparatus includes a transmitter for sending a variable length data slot signal comprising digital data in response to the state of the transmission queue. The nodal apparatus also includes a receiver for receiving a variable length data slot signal. Sponsorship: Illinois Institute of Technology United States Patent Show less

Show moreA passive mapping system employs an antenna or other sensing means having a receiving beam pattern which is scanned in azimuth while moving along a path relative to the area to be mapped. The received signal, after detection and other processing, is recorded on a moving record medium in such a manner that each emitting element in the mapped area generates a straight line of a certain intensity or contrast on the record medium with a slope corresponding to the emitting element range, and the position along the medium corresponding to the location of the antenna along the path. Subsequently, the record medium is processed to collapse or integrate each straight signal line into a point on a further record medium to produce a radiometric plan view map of the area.
