    摘要: 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.

    摘要: The antenna of a radio frequency identification (RFID) tag may be detuned by applying a conductive material in radio frequency (RF) contact with the antenna, such that the RFID tag is not operable. This material may later be removed, or the conductive effect of the material eliminated, thus re-tuning the antenna to its design specifications and restoring the RFID tag to an operable condition. In this manner, RFID tags may be manufactured in an inoperable state, to be subsequently made operable through the occurrence of an event, such as scraping off the conductive material.

    摘要: Methods, apparatuses, and systems to identify biometric characteristics of people and things are disclosed. Embodiments generally comprise sensors that contain arrays of pads or electrodes. In various embodiments, current or voltage sources generate quantum tunneling currents from the arrays of pads to biometric components using select elements as ground return paths. In many embodiments, currents sources apply varying magnitudes of voltages to individual pads in the arrays to create the quantum tunneling currents. In these embodiments, the sensors or electronics coupled to the sensors create voltage profiles of the biometric components by measuring the individual magnitudes of voltages. In some embodiments the individual magnitudes of voltages may be acquired via accumulation state machines and stored in random access memory. In many embodiments, the profiles are compared with other voltage profiles to identify people. Some embodiments involve granting access to computing services when the profile matches a known profile.

    摘要: A radio frequency (RFID) reader may modulate a clock signal onto the carrier wave that it transmits to one or more RFID tags, and maintain that clock signal throughout all or most of its transmission (which in some embodiments may also be modulated additionally for the transmission of data). An RFID tag receiving that signal may synchronize its own internal clock to that received clock signal, and use its own internal clock as a reference clock for its own transmission. By continuing to synchronize on the clock signal from the RFID reader, the RFID tag's transmission data rate may be prevented from drifting excessively.
