Abstract: An illustrative method includes determining a preliminary estimate of the patient's tinnitus tone by allowing the patient to listen to and vary frequency and intensity of a first test tone within a predetermined first frequency range and a predetermined first intensity range to approximate the first test tone to the patient's tinnitus tone; defining a second frequency range and a second intensity range around the preliminary estimate of the patient's tinnitus tone; and determining a final estimate of the patient's tinnitus tone by allowing the patient to listen to and vary frequency and intensity of a second test tone within the second frequency range and the second intensity range to approximate the second test tone to the patient's tinnitus tone.

Abstract: A device may include a first locking mechanism configured to connect a first end of the device to a needle, a second locking mechanism configured to connect a second end of the device to a syringe, a pressure transducer, a microprocessor and a light emitting diode. The pressure transducer may be configured to measure a first pressure at a first time and a second pressure at a second time. The microprocessor may be configured to receive the first pressure and the second pressure from the pressure transducer, determine a pressure difference between the first pressure and the second pressure, and determine a time difference between the first time and the second time. The light emitting diode may be configured to signal when the needle is properly situated based on the pressure difference and the time difference.

Abstract: System and methods of detecting and measuring periodontal disease comprising filling a periodontal pocket with a fluid capable of propagating sound waves, transmitting a sound wave into the periodontal pocket, sensing the return sound wave from the periodontal pocket, and determining the depth of the pocket by measuring the time it takes the at least one transmitted sound wave to traverse the periodontal pocket and return. A peak discrimination analysis algorithm is also provided.

Abstract: The present invention provides automated devices for use in supporting various cell therapies and tissue engineering methods. The present invention provides an automated cell separation apparatus capable of separating cells from a tissue sample for use in cell therapies and/or tissue engineering. The cell separation apparatus can be used in combination with complementary devices such as cell collection device and/or a sodding apparatus to support various therapies. The automated apparatus includes media and tissue dissociating chemical reservoirs, filters, a cell separator and a perfusion flow loop through a graft chamber which supports a graft substrate or other endovascular device. The present invention further provides methods for using the tissue grafts and cell samples prepared by the devices described herein in a multitude of therapies including revascularization, regeneration and reconstruction of tissues and organs, as well as treatment and prevention of diseases.
