  • Patent number: 9333535
    Abstract: A micromachined ultrasonic transducer (MUT) circuit, which has a MUT with a MUT membrane that can vibrate back and forth to transmit an ultrasonic wave, electrically controls the movement of the MUT membrane by controllably transferring energy to the MUT membrane, thereby allowing the MUT membrane to transmit substantially any desired ultrasonic wave.

  • Patent number: 8686839
    Abstract: A system includes an actuator configured to generate vibrations for creating tactile feedback to a user. The system also includes a sensor configured to measure the vibrations generated by the actuator. The system further includes a tactile feedback system configured to drive the actuator in order to generate the vibrations. The tactile feedback system is configured to adjust the driving of the actuator in response to measurements from the sensor. The actuator could include a motor configured to drive an eccentric mass, and the sensor could include an accelerometer and/or a gyroscope. Among other things, the tactile feedback system could be configured to over-drive a motor of the actuator until the measurements from the sensor indicate that vibrations are detected by the sensor and to back-drive the motor of the actuator until the measurements from the sensor indicate that no vibrations are detected by the sensor.

  • Patent number: 8674961
    Abstract: A method includes identifying a position of a user's touch on a touch screen, a velocity of the user's touch across the touch screen, and a pressure of the user's touch on the touch screen. The method also includes generating at least one drive signal for driving one or more actuators associated with the touch screen and outputting the at least one drive signal. The at least one drive signal is configured to cause the one or more actuators to generate a desired haptic texture on the touch screen. The at least one drive signal is based on the position, the velocity, and the pressure. For example, a waveform of the at least one drive signal could be based on the position. Also, groups of pulses in the at least one drive signal could have a frequency and waveform based on the velocity or an amplitude based on the pressure.

  • Publication number: 20130182539
    Abstract: A method includes identifying a position of a static reflector near an ultrasonic transmitter. The method also includes transmitting ultrasonic signals from the ultrasonic transmitter. The method further includes receiving reflected ultrasonic signals at an ultrasonic receiver, where the received ultrasonic signals include a direct reflection directly from a target and a multipath reflection indirectly from the target via the reflector. In addition, the method includes identifying a location of the target using the reflections and the identified position of the reflector. The identified position of the reflector can be used to determine which pulses in the received ultrasonic signals are from the direct reflection and which pulses in the received ultrasonic signals are from the multipath reflection. The pulses in the received ultrasonic signals from the multipath reflection could be discarded or combined with the pulses in the received ultrasonic signals from the direct reflection.

  • Patent number: 8451098
    Abstract: Various embodiments of the invention combine a passive RFID tag with a manually switchable battery for additional transmit range when needed. In some embodiments, connecting the battery may also modify the contents of the data transmitted from the RFID tag. This feature may be particularly useful in applications in which a device generally only needs to identify itself as being in a small area, but may occasionally need to send out an alert with greater range.

  • Patent number: 8044773
    Abstract: Various embodiments of the invention may use code division multiple access (CDMA) technology in communications from radio frequency identification (RFID) tags to RFID readers, so that multiple RFID tags may respond to the same RFID reader at the same time on the same frequency and still be reliably decoded by the RFID reader. In some embodiments, orthogonal CDMA PN sequences for the RFID tags to use in creating their responses may first be transmitted to those RFID tags, possibly using a non-CDMA technique.

  • Patent number: 7986235
    Abstract: A receive-only supplemental radio frequency identification (RFID) reader may receive response signals from RFID tags, digitize and interpret those signals, and transfer the resulting data to a primary RFID reader. By relieving the primary RFID reader of some or all of the tasks of receiving, demodulating, and decoding concurrent responses from multiple RFID tags, the primary RFID reader may be made less expensive and/or may devote its resources to other tasks.
