  • Patent number: 9876421
    Abstract: A power supply controller having a shortened reset time due to a small hiccup voltage includes an electrical circuit providing a repeated voltage hiccup of a supply voltage of the controller of a switched-mode power supply (SMPS) when the controller enters a latched state. A plurality of comparators each have an input coupled with the controller supply voltage. A multiplexer and two latches are included, each coupled with one or more comparator outputs, and a restart controller is coupled with an output of one of the latches. The restart controller in various implementations toggles a switch to activate and deactivate a current sink to create the supply voltage hiccup. In other implementations, the switch is excluded and the restart controller toggles a voltage startup transistor to couple and decouple a voltage source with the supply voltage to create the voltage hiccup.

  • Patent number: 9601098
    Abstract: The present application includes a system configured to tune multiple instrument simultaneously. The system includes a plurality of frequency sensors, each in communication with a single instrument. The frequency sensor senses a pitch played from the respective instrument and transmits that pitch frequency to a single tuner for processing. The tuner compares each pitch frequency to a base reference. The base reference for each instrument may be different depending on the pitch played by the instruments. The pitch frequency is compared to the base reference and a deviation is produced. The deviation is transmitted and displayed on a readout for use by the musician to make adjustments to the instrument based upon the deviation. An additional readout is also provided to a third party operator for viewing.

  • Patent number: 9357296
    Abstract: A switch control circuit monitors a signal produced by a MEMS or other capacitor microphone. When a criterion is met, for example when the amplitude of the monitored signal exceeds a threshold or the monitored signal has been clipped or analysis of the monitored signal indicates clipping is imminent or likely, the switch control circuit operates one or more switches so as to selectively connect one or more capacitors to a signal line from the microphone, i.e., so as to connect a selected capacitance to the signal line to attenuate the signal from the microphone and, therefore, avoid clipping. The switches may be MOSFET, MEMS or other types of switches co-located with the microphone in a common semiconductor package. Similarly, the capacitors, a circuit that processes the signals from the microphone and/or the switch control circuit may be co-located with the microphone in a common semiconductor package.

    Abstract: The resonant drum head mounted speaker cone retrofit kit improves the sound of the drum on audio recordings and in live sound situations and changes the way the drum is miked in live and studio applications. The center of the resonant drumhead is cut out and a speaker cone assembly is attached thereon facing outwards. The speaker cone, which also vibrates from this pressure, now becomes the miked surface of the instrument. Using otherwise conventional miking techniques, a wider range of attack and tone characteristics can be obtained from the drumhead. Additionally, the use of varying speaker cone sizing, an audio foam dust cap, and cone composition options and differences in drum head tension, also contribute to define and tune the sound characteristics based on end user preference.

  • Patent number: 8569605
    Abstract: Instrument having automatic fine-tuning of pitch with no moving parts. A flute is described as one embodiment. In flutes of the prior art the various notes are often slightly off pitch because of compromises in the locations of the holes, and musicians must compensate. In this invention a built-in electronic sensor picks up sound as a musician plays, and a circuit identifies the intended note. The played note is compared with, an accurate reference pitch and the frequency difference is used to generate a signal in phase quadrature with the played note. The quadrature signal is added to correct the pitch. The added vibration energizes a tuning actuator that is located in place of a conventional tuning plug of the flute. The tuning actuator pulls the pitch automatically to achieve a precisely correct pitch as each note is played. Also, a player can intentionally deflect the pitch.

  • Patent number: 8455748
    Abstract: A pitch detection device in which a frequency can be lowered after having maintained both a pitch error accuracy and a response time at practical values to reduce current consumption. Because a number of times of cumulative addition is changed in response to a pitch of a measured signal, a cumulative addition time sum equals or exceeds a constant T_SUM_MIN. Accordingly, a pitch error accuracy of the measured signal achieves a required error accuracy. Furthermore, a frequency of the clock signal is decided using a numerical formula (6) and a numerical formula (7) so that the constant T_SUM_MIN does not exceed a required response time. Accordingly, a response time is within the required response time regardless of whether the frequency of the measured signal is lowered.

  • Publication number: 20130014631
    Abstract: Instrument having automatic fine-tuning of pitch with no moving parts. In prior flutes the notes are slightly off pitch because of compromises in locations of the holes, and musicians must compensate. In this invention a sensor picks up sound and a circuit identifies the played note. The played note is compared with a frequency reference, in a closed loop. The frequency difference generates an additional signal in phase quadrature relationship with the played note. A tuning actuator at one end adds the quadrature signal to correct the pitch by altering its phase. The closed loop causes the tone to have precisely correct pitch. A feature permits a player to intentionally deflect the pitch for artistic expression.
