  • Patent number: 9463332
    Abstract: Portable therapeutic treatment devices and methods with a triangular arrangement of crystals in an induction coil with an external wrapped coil for sensing effected area body part emissions. A biosensor/bioscanner sensor can be used as an indicator to find an effected body part needing treatment and determine when treatment has been effective. The device can be passed over a body until a RED LED light indicates an effected part needing treatment. Treatment can occur with approximately 8 Hz emissions, and the sensor will indicate when the effected area has reached a treated state of approximately 8 Hz by lighting a GREEN LED light. Treatment can occur within approximately 2 minutes. A variety of ailments can be treated such as but not limited to inflammations, nerve problems, joint-pain, muscle-pain, gall bladder problems, and the like.

  • Patent number: 9445536
    Abstract: A crystal oscillator fabrication method includes depositing mounting cement onto first and second mounting pads on a substrate to thereby define first and second electrode adhesion bumps. First and second electrodes of a crystal oscillator are electrically connected to the first and second mounting pads by contacting the first and second electrodes to the first and second electrode adhesion bumps and then curing the adhesion bumps. Next, mounting cement is deposited onto the first electrode and onto a portion of the first electrode adhesion bump to thereby define a top electrode adhesion extension. The top electrode adhesion extension is then cured.
