A custom-fit in-ear-monitor (IEM) is provided that utilizes a plurality of drivers and a single piece driver module that significantly simplifies fabrication while insuring that the completed IEM achieves the desired acoustic performance. The driver module, which is fit within a custom-fit ear mold shell, includes a plurality of driver ports to which the drivers are coupled. The driver module also includes an acoustic output member that includes one or more sound bores that acoustically couple the acoustic output surface of the custom-fit ear mold shell to the plurality of driver ports via a plurality of sound ducts within the driver module.

The present disclosure generally provides an apparatus and method of providing a performer with a desired combined mix of one or more performer's voices, instruments and/or music tracks with minimal or no overall effect on the setup of the sound system in a venue, such as a concert venue, recording studio or other type of musical gathering in which the performer is performing. The disclosure provided herein generally includes the use of an audio signal intercepting device that is inserted within and/or coupled to a portion of a sound system at a venue to provide the performer with a desired custom monitor mix of one or more performer's voices, instruments and/or music tracks.

Audio monitor signal interception device

A method of fabricating a custom-fit in-ear-monitor (IEM) is provided that utilizes a pre-tuned, single piece driver module to simplify fabrication and reduce cost while insuring that the performance of the IEM consistently meets the acoustic goals set for the device. During fabrication the driver module, the drivers coupled to the module's driver ports, and the crossover circuit are installed in a custom-fit IEM shell such that the module's acoustic output is aligned with the output surface of the IEM shell. After installing the device components within the IEM shell, the shell is sealed.

Manufacturing process for a custom fit in-ear monitor utilizing a single piece driver module

Performance of mass flow controller may be vulnerable to pressure transients in a flow path to which the controller is coupled for the purpose of controlling the fluid flow. A system and method are provided for reducing or eliminate performance degradations, instabilities, and/or inaccuracies of a mass flow controller caused by changes in the pressure environment. In particular, a method and system are provided for compensating for pressure transients in the pressure environment of a flow path and mass flow controller.

Methods and apparatus for pressure compensation in a mass flow controller

A in-ear monitor is provided that is coupleable to an external audio source and that may be configured as a custom fit IEM or configured to accept a removable eartip, the in-ear monitor including at least two drivers and at least two concentric sound delivery tubes that acoustically couple the audio output from each of the drivers to the acoustic output surface of the in-ear monitor.

In-ear monitor with concentric sound bore configuration

A multi-driver, in-ear monitor is provided that is coupleable to an external audio source, for example via a source input cable or a wireless receiver. A circuit, for example comprising a passive or active crossover circuit, receives the electrical signal from the external audio source and provides separate input signals to the drivers contained within the in-ear monitor. A plurality of sound delivery tubes acoustically couple the audio output from each of the drivers to the acoustic output surface of the in-ear monitor. The in-ear monitor may be configured as a custom fit IEM or configured to accept a removable eartip. The plurality of sound delivery tubes may be comprised of a pair of concentric tubes; a pair of concentric tubes and a discrete tube; or three concentric tubes.

A system and method for controlling a mass flow controller to have a constant control loop gain under a variety of different types of fluids and operating conditions, and for configuring the mass flow controller for operation with a fluid and/or operating conditions different from that used during a production of the mass flow controller. Further, the system and method includes providing control by reducing the effects of hysteresis in solenoid actuated devices by providing a non-operational signal to the solenoid actuated device.
