  • Patent number: 9579028
    Abstract: A system for detecting abnormalities or inconsistencies and a method to utilize the same are provided. In particular, a computer system may be adapted to detect the abnormality or inconsistency within at least a portion of a subject by generating internal impedance data which indicates that an impedance change within the portion of the subject has occurred. For example, the impedance change may be associated with a change in at least one characteristic of a blood vessel within the subject (such as a change in a fluid flow rate within at least a portion of the subject), a change in a fluid volume within at least a portion of the subject, etc. The impedance change also may be associated with the presence of a foreign object within the portion of the subject. In an exemplary embodiment, it is possible to detect the abnormality or inconsistency within the subject by generating a continuous, real time internal impedance map indicating the impedance change within the subject.

  • Patent number: 9572645
    Abstract: A closed system mouthpiece uses light and heat generation to activate a gel formulation to increase its volume. The gel formulation is coated into the mouthpiece, which is inserted into the user's mouth. Application of heat above a threshold temperature causes the gel to transform into foam and expand out of the mouthpiece and into the oral cavity. The mouthpiece creates a hermetic seal such that the foam expands out throughout the oral cavity into nooks and crannies that are normally difficult to access. Activation of a light source embedded within the mouthpiece enhances the bacteria killing properties of the foam material. The pH balance of the mouth is restored by the inventive method and apparatus to a neutral level in the range of 6.75 to 7.25.

  • Patent number: 9474485
    Abstract: A blood pressure measurement device includes a cuff, a display, a distance sensor, an acceleration sensor, and a CPU. The display displays a positional relationship between the patient's heart and the device, which includes a flat screen. The distance sensor measures a distance between the device and the patient, and detects a subject to be measured on a line perpendicular to the flat screen of the display and measures the distance. The acceleration sensor measures an angle of inclination of the device when mounted on the patient's wrist. The CPU calculates a positional relationship between the patient's heart and the device based on the distance between the device and the subject to be measured, the angle of inclination of the device mounted on the patient's wrist, the length of the patient's forearm and upper arm, and a vertical distance between the patient's shoulder and heart.

  • Patent number: 9449225
    Abstract: A neuronal recording system featuring a large number of electrodes and a portable wireless front-end integrated circuit for signal processing for low-power spike detection and alignment. The system is configured as a Neuroprocessor and introduces hardware architectures for automatic spike detection and alignment algorithms. The Neuroprocessor can be placed next to the recording electrodes and provide for all stages of spike processing, stimulating neuronal tissues and wireless communications to a host computer. Some of the algorithms are based on principal component analysis (PCA). Others employ a novel Integral Transform. The algorithms execute autonomously, but require off-line training and setting of computational parameters. Pre-recorded neuronal signals evaluate the accuracy of the proposed algorithms and architectures: The recorded data are processed by a standard PCA spike sorting software algorithm, as well as by the several hardware algorithms, and the outcomes are compared.
