Abstract: A device and method for performing coronary artery grafting on a model heart. In one embodiment, a motor-operated cam displaces a surface on which a model cardiac vasculature is mounted or integrated. The active surface moves to simulate the beating of the heart during a live operation. The trainee performs the simulated procedure while the model heart pulsates.

Abstract: A simulated ammunition round (1) is characterised by a gunfire simulator (4) having a combustion chamber (28), means (21) for admitting fuel gas to the combustion chamber, ignition means (23) for igniting fuel gas in the combustion chamber to cause an explosion and an exhaust port (51) in the combustion chamber. The simulated ammunition round may comprise outlet valve means (14), e.g. a collapsible or frangible diaphragm, for closing the exhaust port and arranged to open rapidly and with audible results in response to explosive pressure rise within the combustion chamber. The simulated ammunition round may comprise means (38, 41) to enable firing of the round, the enabling means being responsive to loading of the round into the receiving chamber of a weapon.

Abstract: An interactive modular educational system. This invention provides for an interactive modular educational system comprised of a deck of visually-enhanced cards designed to allow users to learn important business-related techniques, tactics, and strategies. The cards, divided into sections based upon different business principles, utilize color schemes, similarly sounding word endings, acronyms, and clever sketches to allow the user to learn or improve upon a variety of business disciplines. The system, which can be used randomly, modularly, or sequentially, provides an easy-to-use, easy-to-understand method of learning and remembering valuable business techniques.

Abstract: A system and method which enables individuals to manipulate text retrieved by a computer in such a manner that the computer user can rapidly and accurately obtain information about the contents of a retrieved body of text without reading the text. If a computer retrieves text that is too large to display on a single computer screen, the present invention creates a map box on the computer screen. The map box is displayed along with a portion of the retrieved text. Within the map box is displayed a representation of the entire body of text. Using a screen icon, a user can point to any place in the representation of the body of text. The portion of the body of text pointed to then becomes displayed on the computer screen. Furthermore, the representation of the text in the map box can be mapped in different ways to help inform the computer user as to the contents of the body of text prior to that text being read.

Abstract: An aerial decoy comprising a fuselage having forward and aft ends. Disposed within the fuselage are a plurality of decoy discs. Rotatably connected to the forward end of the fuselage is a ram air turbine which is cooperatively engaged to the decoy discs such that the rotation of the ram air turbine facilitates the dispensation of the decoy discs from the aft end of the fuselage.

Abstract: A educational card game for teaching phonetic pronunciation of words and letters. The educational card game includes a plurality of cards, each of the plurality of cards includes a face side and represents a different letter of the alphabet. The letter of the alphabet represented by each card is printed in a central portion of the face side and a point value assigned to each card is printed in a corner of the face side. A device for storing data representing an oral pronunciation of each letter printed on each of the plurality of cards is included to provide a correct oral pronunciation of each letter on each card. The data representing the phonetic pronunciation of each letter is assigned a respective location within the data storage device.

Abstract: A training device, for mounting to a standard door having a cutout at middle height, the door mounted in a door frame having a strike plate at middle height. A sliding box is mounted in the cutout for slidable motion toward and away from the strike plate. At least one spring is mounted between the sliding box and the cutout for biasing the sliding box toward the strike plate. The spring is selected to resist compression and thus motion of the sliding box away from the strike plate. The amount of resistance that the spring provides is equivalent to the amount of resistance presented by a doorknob and locking assembly on standard doors. Thus, a crowbar-like tool may be used to pry the sliding box away from the strike plate to open the door and simulate the force and action necessary to pry open any standard door.

Abstract: A training unit generally includes a processor, a magnetic field sensor, a plurality of control switches, and a message and data output device. Placing a PEIS magnet, constructed in accordance with the ISOWD 14994 standard, adjacent to or in contact with the training unit activates the magnetic field sensor, a condition detectable by the processor. Activation of the switches determines which of three modes the training unit will operate. In an instructional mode, the process provides instructional messages to the operator via the message and data output device, which preferably includes a display and an audio speaker. In a coached mode, the training unit informs the operator when to place the magnet adjacent to or in contact with the training unit and when to remove the magnet in accordance with the timing intervals of the PEIS entry code. In a practice mode, the operator initiates and completes the entry code using a PEIS magnet without coaching.

Abstract: An image display device preferably used for educational applications is disclosed. In the image display device, an instructor gives a lecture while seeing an original document without being disturbed by any element of the device. In addition, a video camera, which is detachably attached to the camera mount, may be tilted to the left or right or tilted upward or downward so that it is not required to move the original document when the left, right, upper or lower side of the document has to be picked up by the camera. The above display device also includes a means used as either a whiteboard or an OHP-filmed image revealing panel. The device thus improves educational effect when it is used for educational applications. The device is not expensive thus being widely used for educational applications without forcing excessive costs on the owner.
