Patent number: 7501631Abstract: An electronic imaging sensor, which has an improved immunity to noise caused by unwanted x-rays, images an object by collecting charge carriers produced in the sensor when the object is exposed to x-rays. One or more shielding areas are formed proximate the sensor to capture or sweep away any undesirable charge carriers generated by the unwanted x-rays. The shielding areas extend deeper beneath the surface of the sensor than the depth at which the desired charge carriers corresponding to the object being imaged is collected. The shielding areas capture charge carriers formed by the unwanted x-rays, which penetrate into the sensor to a greater depth than the depth at which the. desired charge carriers are collected. In this way, the undesirable charge carriers are captured near the region where they are generated and before they migrate towards the surface where they can be collected and manifest as noise in the resulting image of the object.Type: GrantFiled: October 7, 2005Date of Patent: March 10, 2009Assignee: Schick Technologies, Inc.Inventors: Stan Mandelkern, David Schick, Barmak Mansoorian, Daniel Van Blerkom

Patent number: 7471761Abstract: A method of computing oral bone mineral density using a panoramic x-ray system. A reference phantom having a known density is provided. A digital panoramic image of a body part and the reference phantom is obtained by irradiating the body part and the reference phantom. The reference phantom is disposed in a location free from anatomical features and in the same scan line as the body part. A relationship is established between a region of the image corresponding to a portion of the body part and a region of the image corresponding to the reference phantom. Bone mineral density is calculated based upon the established relationship and the known density of the reference phantom.Type: GrantFiled: September 15, 2005Date of Patent: December 30, 2008Assignee: Schick Technologies, Inc.Inventor: Daniel Michaeli

Patent number: 7193219Abstract: 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.Type: GrantFiled: May 1, 2006Date of Patent: March 20, 2007Assignee: Schick Technologies, Inc.Inventors: David B.

Patent number: 7171181Abstract: 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).Type: GrantFiled: August 11, 2003Date of Patent: January 30, 2007Assignee: Schick Technologies, Inc.Inventors: David B. Schick, Stan Mandelkern, Iouri Kazarov, Leonid Khatutskiy, Valeriy Armencha
