  • Patent number: 7551720
    Abstract: An x-ray system comprises an x-ray tube, covered by a housing, which emits x-rays therefrom, and a receiver mounted within the x-ray tube housing. An electronic sensor receives the emitted x-rays, converts the received x-rays into electrical image data signals, and transmits the electrical image data signals to the receiver. An image processing unit processes the electrical image data signals received from the receiver.

  • Publication number: 20080128012
    Abstract: A method for generating electricity from a ground source. A temperature differential is created across a thermoelectric generator by passing a first fluid that has been maintained at air temperature over one side of the generator, and passing a second fluid that has been maintained at ground temperature over the other side of the generator. Electricity is generated from a voltage induced by the temperature differential across the thermoelectric generator.

  • Patent number: 7193219
    Abstract: An intraoral sensor includes a radiation sensitive sensor array, an event detection circuit, and a transmitter. The radiation sensitive sensor array includes a scintillator which converts x-rays into visible light radiation, and a plurality of pixels sensitive to visible light radiation to capture an image upon the presence of incident radiation. The event detection circuit includes a current sensing device and is configured to generate a triggering signal indicating the presence of radiation incident on the sensor array based upon the amount of electrical current drawn by the sensor array. The transmitter is adapted to transmit via a wireless link signals representing an image captured by the sensor array.

  • Patent number: 7171181
    Abstract: An automatic frequency tuning (AFT) system which can effect immediate and accurate automatic frequency tuning of the local oscillator (LO) of a receiver, in order to achieve a stable intermediate frequency (IF) signal while reducing the power consumption and the cost of the system. In the automatic frequency tuning (AFT) system, an analog-to-digital converter (ADC) converts the intermediate frequency (IF) to a digital value which is sent to a microcontroller. A signal sent from the microcontroller accurately and automatically tunes the local oscillator (LO).

  • Patent number: 7072443
    Abstract: A system for capturing multiple intraoral images includes an intraoral sensor. The sensor includes a sensor array, a transmitter and a power source that provides power to the sensor array and the transmitter. The sensor is configured to be inserted inside a patient's oral cavity, capture an image upon the presence of incident radiation and transmit from within the oral cavity via a wireless link electrical signals representing the image. A base station positioned outside the oral cavity is configured to receive the electrical signals transmitted from the sensor. The sensor is capable of capturing transmitting to the base station electrical signals representing multiple intraoral images without requiring that the sensor be removed from the patient's oral cavity.

  • Patent number: 5995583
    Abstract: A method and apparatus for producing a X-ray image of a patient's teeth by placing an intra-oral sensor having a plurality of pixels disposed in a linear array inside the patient's mouth, and moving a radiation source around outside of the patient's mouth. The intra-oral sensor detects the radiation that has passed through the patient's teeth and generates corresponding output signals that depend on the amount of radiation arriving at each pixel. The information contained in the output signals is stored and can be used to create an X-ray image of the patient's teeth. The intra-oral sensor can be moved about inside the patient's mouth in coordination with the movement of the radiation source in order to improve the resulting image quality. This method and apparatus can be used to obtain an X-ray image of any number of teeth, including a panoramic image of all of the patient's teeth, in a single, quick, uninterrupted operation.
