Abstract: The present invention is a wireless alarm system having a transmitter which operates in conjunction with existing intruder detection devices to provide an electromagnetic signal in response to detection of an intruder. The transmitter is attached to, and is pulsed by the detection device. In response to the pulse, a signal is emitted by the transmitter, and is sent to a receiver unit which is electrically connected to a power source remote from the transmitter. The receiver is provided with an electrical switching mechanism and an alarm selection device. When a signal from the transmitter is received by the receiver, the power from the power source is switched by the receiver so as to actuate one or more of selected alarms or electrical components which may be an integral part of or be attached directly to the receiver, or may be located remotely therefrom.

Abstract: Apparatus and method for separation, recovery, and recycling municipal solid waste and the like by introducing solid waste materials into a rotatable pressure vessel, rotating, pressurizing, adding pH controlling chemicals and heating the pressure vessel and thus the waste material while simultaneously applying a mixing action to the solid waste material. The addition of a predetermined amount of pH controlling chemicals and the application of a vacuum serve to control the moisture content of the final fine organic portion of the processed material. Organic contents of the vessel are pulped and sterilized when processed to facilitate ease of separation and prepare the resulting cellulose material for use.

Abstract: A system utilizing an array of high speed video cameras with image processors coupled to data microprocessors, data memory devices, video monitors, control terminals, printout devices, and related hardware and software. The system functions to identify, track, display and record all or selected portions of the path of one or more golf balls from the time each ball is struck, or after it is in flight, until it reaches its final point of rest. The recorded tracking information may be displayed in selected forms such as video or audio replays of the actual golf shot or selected portions thereof, or by printed data in character or graphic form. The tracking information may be reviewed for detailed study of all or portions of the track of the golf shot as well as the final resting place of the ball with respect to the intended target of the shot.

Abstract: An orthopedic traction apparatus for use with an adjustable hospital bed and capable of being operated by a patient within the bed to independently get in and out of the traction apparatus without the help of another person.

Abstract: A portable microcomputer inventory system including a plurality of components and a support for supporting the components on an user as the user inventories items that have a bar code disposed thereon. The components include a microcomputer, a handheld bar code scanner for scanning the bar code on items to be inventoried, a visual display device carried on the user to display information relative to the item being inventoried, a keypad for accessing the computer and a rechargeable battery pac for supplying electrical power to the components of the inventory system.

Abstract: A method and apparatus for detecting the seismic signal generated by a tornado and providing timely warning of the tornado's approach. The invention involves the use of a geophone or velocity transducer (3) to detect the seismic surface waves generated by the tornado. The output of the geophone passes to the microchip (4) installed with the alarm system (5) within the building (6). Within the microchip the signal passes through the A/D converter (7), to the band-pass filter (8), and then to the signal-to-noise comparator (9). When the signal-to-noise ratio exceeds a specified level, the switch (10) is closed and the alarm (5) is activated.

Abstract: Apparatus and method for supporting at least a portion of an article while the article is being formed. A source of self-adhering particles is directed by a particle jetting device, or the like, to a predetermined position in a controlled environment to form the article. A support structure is carried in the controlled environment for substantially rigidly supporting at least a portion of the article during the formation of the article (by build-up of the self-adhering particles). The support structure is a fluid which changes state to a solid responsive to an electrical charge and reverts back to a fluid responsive to removal of the electrical charge.

Abstract: An optical filter which blocks a substantial portion of a selected color of the visual light spectrum from entering one eye. The selected portion is the normal color of an object which is to be viewed by both eyes. The other eye is simultaneously allowed to have a substantial portion of the selected color to enter it. When used to aid a hunter in tracking a blood trail, a substantial portion of the red color (more than 50%) of the blood is blocked from entering one eye while the other eye is allowed to receive a substantial portion (more than 50%) of the red color.

Abstract: Apparatus and method for separation, recovery, and recycling municipal solid waste and the like by introducing solid waste materials into a pressure vessel having a rotatable section. The vessel is disposed for subjecting the waste material to heat and pressure while simultaneously applying an extruding action to the solid waste material. The extruding action is achieved by a rotatable extruder mechanism carried in the pressure vessel and rotated in response to the rotating section thereof. The rotation forces the processed solid waste material through a pair of constricted areas before the waste material is expelled from the pressure vessel by rotation of the extruder mechanism.

Abstract: A portable (removable) tongue for connecting a house trailer to a towing vehicle for towing the trailer from one location to another with the tongue being adapted for easy and rapid disconnection from the towing vehicle and trailer. The tongue is adapted to be attached to, and removed from, the frame which supports a house trailer and includes a coupler and hitch lock, a pair of arms connected to and diverging from the coupler and hitch lock, a pair of male coupling members secured to the free ends of each arm, and a pair of female coupling members adapted to be secured to the frame of the trailer, and a clip for locking each male coupling member to a respective female coupling member. The tongue is adapted to be readily secured to the frame of the trailer for towing purposes and easily removed from the frame of the trailer while the trailer is parked in a trailer court for living purposes.

Abstract: Powdered metal composition consisting essentially of carbon, copper, solid lubricant particles, carbide-enriched alloys and iron and process for sintering to yield alloyed components exhibiting improved mechanical, physical and wear-resistent properties.

Abstract: Apparatus for detecting and identifying, by video imagery, an object such as a helicopter, having a characteristic temporal signature containing phase and magnitude information. The object is acquired and the video signals are stored and then temporally filtered by a FFT on a pixel to pixel basis. The magnitude and phase of pixel at a predetermined frequency is determined and compared with periodic frequencies generated by known objects, such as helicopter rotors, to determine if the frequency generated by the object matches any of the known frequencies. Further processing determines the number of blades and directions of rotation of the blades which removes ambiguities from frequency only processing.
