Title: Tester for automotive trailer light systems
Inventor: SYRACUSE CARMELO R
IPC: B60Q11/00
Filed: 1998-10-13
Abstract: The tester includes mating electrical connectors which permit the tester to be positioned between the respective plugs of the respective electrical cables running between a towing vehicle and from a trailer. The container for the tester preferably has magnetic strips along its bottom surface to permit temporary attachment to either the tongue of the trailer or the rear of the towing vehicle. The essential features of the tester are limited to only two simple single-pole/double-throw switches, positioned in tandem, and three diodes arranged as a simple "OR" gate in combination with an audio signal device. This simple circuitry permits a single operator to check (a) the integrity of the wiring harness connected to the towing vehicle's lighting circuits, without leaving the driver's seat of the towing vehicle, and (b) the integrity of the trailer lighting with two simple switch adjustments. Means are also provided for checking for a bad ground connection, and an auxiliary power supply can be used with the tester to permit checking of trailer lighting circuits without the presence of a towing vehicle.

Title: Recovery of metal from dross
Inventor: TSANTRIZOS PETER G
IPC: F27D1/18
Filed: 1997-04-10
Abstract: A process and an apparatus are disclosed for improved recovery of metal from dross, wherein a dross treating furnace is provided with a refractory wall or lining with good capacity to store and conduct heat. This furnace is preheated to a desired temperature by injection of oxygen to burn non-recoverable metal remaining in the residue after tapping of the recoverable metal contained in the dross. When dross is treated in such preheated furnace, the heat emanating by conduction from the furnace wall is sufficient to melt and separate the recoverable metal contained in the dross, without addition of an external heat source, such as fuel or gas burners, plasma torches or electric arcs.

Title: Means and methods for the treatment of neurological disorders
Inventor: FISCHELL DAVID R
IPC: A61N1/36
Filed: 1998-10-26
Abstract: Disclosed is a multiple electrode, closed-loop, responsive system for the treatment of certain neurological diseases such as epilepsy, migraine headaches and Parkinson's disease. Brain electrodes would be placed in close proximity to the brain or deep within brain tissue. When a neurological event such as the onset of an epileptic seizure occurs, EEG signals from the electrodes are processed by signal conditioning means in a control module that can be placed beneath the patient's scalp, within the patient's chest, or situated externally on the patient. Neurological event detection means in the control module will then cause a response to be generated for stopping the neurological event. The response could be an electrical signal to brain electrodes or to electrodes located remotely in the patient's body. The response could also be the release of medication or the application of a sensory input such as sound, light or mechanical vibration or electrical stimulation of the skin. The response to the neurological event can originate from devices either internal or external to the patient. The system also has the capability for multi-channel recording of EEG related signals that occur both before and after the detection of a neurological event. Programmability of many different operating parameters of the system by means of external equipment provides adaptability for treating patients who manifest different symptoms and who respond differently to the response generated by the system.

Title: A portable wheelbarrow
Inventor: HADAVAND-MIRZAIE MANOUCHEHR
IPC: B62B5/00
Filed: 1998-12-15
Abstract: A new portable wheelbarrow is designed to dump the load sideways easily, quickly, and safely with the use of a pedal located at the rear end of the shaft that is placed underneath the load container. It has a capacity of approximately 65 cubicdecimeters.  This wheelbarrow is mainly consists of three wheels, a frame, a pedal, a handle, and a load container. The front wheel of this wheelbarrow is free to rotate allowing the operator to turn the device 360 degrees. A latch located above the dumping handle holds the load container in a normal position that should be removed before using the pedal.  Since three wheels support the wheelbarrow, the operator dose not need to lift and carry the load. Therefore the operation of this wheelbarrow involves less physical work while is more efficient compared to the ordinary wheelbarrows. This wheelbarrow is mostly made of aluminum, easy to assemble, and capable of transporting heavy loads due to its unique structure. All different parts of the wheelbarrow can be placed in a 121 cm *  60cm* 20cm box or a case (where the height of the box is 20cm). One of the important aspects of this wheelbarrow is that a wide range of users such as a child or an old person can use that for various applications

Title: Resuscitator device with self closing valve
Inventor: EISENBERG MELVIN I
IPC: A61M16/00
Filed: 1998-12-17
Abstract: A mouth-to-mouth resuscitator device for providing a physical barrier between a rescuer and a victim. The device comprises a flexible face shield having an opening formed therein. A tubular housing is sealed to the shield around the periphery of the opening and includes a rescuer air input end accessed from one side of the shield, and a victim air output end disposed on the opposite side of the shield. A self-closing one way valve arrangement comprising a flexible valve disc is contained in the housing to permit exhaled air under pressure to flow from the input end to the output end, and to prevent fluid back flow from the output end to the input end. A plate is secured in the housing to support the disc and provide a hinge for dividing the disc into a pair of flaps. A valve seat having a concave shape is provided to support the valve disc. The valve disc has a convex shape when the valve is closed. One flap of the disc pivots or bends outward from the valve seat in one direction and the other flap of the disc pivots or bends outward from the valve seat in the opposite direction, in response to the forced air applied at the input end by the rescuer for opening the valve and transferring the forced air to the output end; and the flaps resiliently pivot inward in opposite directions toward the input end for positioning on the valve seat to close the valve when the forced air has dissipated. The valve disc is stressed when in the closed-condition due to the valve seat blocking the valve disc from moving to its normal flat configuration. The valve disc abuts the valve seat in response to fluid back flow from the victim output end, to maintain the valve closed; and thereby blocking any fluid back flow from being transferred and discharged at the rescuer air input end. A pair of spaced apart rods are formed on the valve disc for attaching the valve disc to the support plate.

Title: Method for transmitting multiresolution image data in a radio frequency communications system
Inventor: HASSAN AMER
IPC: H04N7/26
Filed: 1997-07-09
Abstract: The present invention relates to a method for transmitting multiresolution image data via wireless devices in a radio frequency communication system wherein images are decomposed into levels of resolution. The image data is stored in discrete information blocks in an image storage unit including a base image and one or more image details. The base image represents the coarsest resolution of the image. Each image detail, when added to the base image, improves the resolution of the image. An image display unit (52) transmits a request for image data to the image storage unit (46). In response to the initial request, the base image is transmitted to the image display unit. If the base image is insufficient, the resolution can be increased incrementally by sending additional image data requests to transmit additional image detail. The additional image detail is then transmitted to the image display unit and recombined with the base image to provide a higher level of resolution to the image.
