  • Patent number: 9606633
    Abstract: The method and apparatus for input to electronic devices include a control circuit and a gyro module. The control circuit includes a microcontroller, where the microcontroller includes a digital bus, a receiver/transmitter module, a plurality of digital input pins, and an analog input pin. The gyro module is connected to the digital bus. The apparatus further includes a plurality of tactile switches connected to the digital pins. Further, a force sensitive resistor and a vibration motor interact with the control circuit. The force sensitive resistor is connected to the analog input pin of the microcontroller through a voltage divider, and the vibration motor is connected to the digital bus of the microcontroller through a motor controller. The apparatus also includes a communications antenna that is connected to the receiver/transmitter module of the microcontroller through a wireless module. A method includes various steps for inputting into an electronic device.

  • Patent number: 5173476
    Abstract: A superconductor consisting of a sufficiently pure phase of the oxides of Bi, Sr, Ca, and Cu to exhibit a resistive zero near 110K resulting from the process of forming a mixture of Bi.sub.2 O.sub.3, SrCO.sub.3, CaCO.sub.3 and CuO into aparticulate compact wherein the atom ratios are Bi.sub.2, Sr.sub.1.2-2.2, Ca.sub.1.8-2.4, Cu.sub.3. Thereafter, heating the particulate compact rapidly in the presence of oxygen to an elevated temperature near the melting point of the oxides to form a sintered compact, and then maintaining the sintered compact at the elevated temperature for a prolonged period of time. The sintered compact is cooled and reground. Thereafter, the reground particulate material is compacted and heated in the presence of oxygen to an elevated temperature near the melting point of the oxide and maintained at the elevated temperature for a time sufficient to provide a sufficiently pure phase to exhibit a resistive zero near 110K.
