Abstract: An interactive Internet-based Coupon Barcode Verification system comprises a central computer system connected to the Internet. The system is adapted to be accessed by one or more authorized personal computers. A browser and keyboard, and optionally a barcode reader, constitute the minimal hardware and software required to verify the validity of barcode data. The barcode data can be transmitted over the Internet to the coupon barcode verification system by means of the keyboard. Alternatively, the barcode reader and the web browser transmits the information. An algorithm logic means analyzes the barcode data provided by the authorized personal computers to determine the validity of the barcode data. The validity determination is based on UCC guidelines, recognized MIN, Family Code, Value Code and EAN-128 Extended Codes. Advantageously, the system enables manufactures to issue coupons having valid barcodes.

Abstract: An electric motor with rotor being a drive wheel. The drive wheel has one or more permanent magnets attached to said drive wheel with opposite magnetic poles adjacent to one another. One or more electromagnets are attached to the structure to which the drive wheel is rotatably connected. A sensor determines the location of the permanent magnets. This information is utilized to assure that the electromagnets are energized only when the resultant magnetic fields will interact with the magnetic fields of the permanent magnet to produce a force on the drive wheel that will cause rotation in the desired direction. Three principal embodiments are employed. In a first embodiment, a computer periodically activates a switch to send pulsed voltage to the electromagnets; the percentage of the period of each pulse during which the voltage is non-zero determines the speed of the drive wheel. In a second embodiment, the computer is replaced with a timing circuit that controls the switch.

Abstract: A motorized skate employing an electric motor with rotor being a drive wheel. A boot or clamp for holding the foot of a user is attached to a rail that supports the boot or clamp. The drive wheel has one or more permanent magnets attached to said drive wheel with opposite magnetic poles adjacent to one another. One or more electromagnets are attached to the rail to which the drive wheel is rotatably connected. A sensor determines the location of the permanent magnets. This information is utilized to assure that the electromagnets are energized only when the resultant magnetic fields will interact with the magnetic fields of the permanent magnet to produce a force on the drive wheel that will cause rotation in the desired direction.

Abstract: A damage detection system for detecting impacts to static structures such as bridges and the like. The damage detection system comprises an impact sensor assembly and impact analyzer system. The impact sensor assembly comprises a pendulum mounted for movement within the impact sensor assembly which is secured to a static structure. The impact analyzer system includes a micro-computer circuit, power means, visual indication means of the pendulum motion and relay circuit means to relay the type and magnitude of pendulum motion to a warning means.

Abstract: An identifying telephone controller system using a main computer component with a central processing unit coupled to an in-house AC wiring system and utilizing a plug-in ringer/appliance controller receive and a base-remote telephone system to provide multi-function telephone operations including caller identification and call patching and remote appliance control.
