  • Publication number: 20090322328
    Abstract: A method and apparatus is described to image a body using electric fields. The electric field is apply to the body from a well controlled electron beam that deposits charge on a glass plate at a particular time and spatial location. This is demonstrated by using the ubiquitous CRT computer monitor. The method is useful in medical imaging and for nondestructive testing. An advantage of the electric field imaging is it requires no ionizing radiation. The use of the computer display allows for proximity detection of a body. A smart control is drawn on the video screen by a program. The control produces and E-field source that occurs at known time in the video refresh. A proximate E-field sensor is used to detect the changes in the signal produced by the button. Changes in the signal level are associated with a proximate body to the button. Detection logic is used to instigate the action of the control.

  • Patent number: 7358742
    Abstract: A method and apparatus is shown for detecting with high sensitivity by allowing the operation of an e-field amplifier without a DC bias resistor shunt with the amplifier input. E-fields produced by an approaching body, or changing E-field of the background, turn on the amplifier from a partial DC bias state with E-field coupling to the power supply of the amplifier. The result is high sensitivity and extremely long battery life. The amplifier is sensitive to transient and quasitatic DC E-field and the AC background signals. The signals are available simultaneously for processing at the output of the amplifier in a DC and AC coupled channel. The resulting signals are passed to a control system.

  • Publication number: 20080028473
    Abstract: A method of storing and receipt of purchase is described allowing convenient access and proof of purchase. The method is applicable to transfer of images, video streams, and movies. A scrambling and method of inaccessibility is claimed to reduce possibility of illegal copies. In addition to a paper copy, an image of the receipt is sent to a website from the point of purchase. The user of the service then has access to tools that allow sorting and monitoring of expenditures, access to special promotions from the stores they frequent, and a certified method of proof of purchase, and return or exchange status, and warranty registration, and warranty insurance. This method of receipt processing allows customers peace of mind by providing convenient access to receipt information even if the paper receipt is lost.

  • Patent number: 7242298
    Abstract: A method and apparatus is invented that provides unambiguously detection of the charge and proximity to an object. The method and apparatus are passive and function by using the background electric fields from electrical power wiring and equipment. The invention is useful for detecting plastic and other charged objects concealed by nonconductive covering materials. Applications of this lead to plastic detectors to scan people and cargo for dangerous dielectric items similar to metal detectors. It is also useful to warn of hazards due to static electricity buildup on objects or individuals. The technology also offers touchless control capability of computers, apparatus, and games, with plastic objects such as pointers, styluses, swords, sticks, and wands. The sensors are able to detect motion while discerning between proximity to bodies with dielectric or plastic objects. It is also useful for providing people, robots, and machines with obstacle avoidance, and vision capabilities.

  • Patent number: 7078911
    Abstract: A method and apparatus are described for interacting with electronic devices through motional commands. The method uses perturbations of the background quasistatic electric fields. The apparatus measures perturbations in electric potential relative to the background. Body movement is recognized by comparing changes in signals over time. Signals collected from sensors are compared with training sets to recognize specified motional commands or gestures. Upon recognizing the commands, the apparatus issues the predetermined response to the motion.

  • Patent number: 6900642
    Abstract: A low cost diagnostic system for testing the airborne static discharge systems and the grounding systems for aircraft. The present invention is a passive electrostatic detection scheme which in one embodiment is an array of inexpensive, miniaturized sensors for measuring the detected E-field disturbances from aircraft. The measurements are taken on the runway upon arrival and indicate whether the aircraft had an appreciable accumulated charge indicating a failure of the electrostatic discharge system. The system further verifies that the ground discharge devices are properly working and any charge is dissipated upon landing. In one embodiment the measurement information is transmitted to a central location where the aircraft and the measurement data are matched and maintenance is scheduled for aircraft having high levels of electrostatic charge.
