Abstract: An audio transducer system, such as in-ear monitors, are connected to an audio base unit, such as a receiver body pack, using a bidirectional serial time-division multiplexed link. The bidirectional connecting cable has a single active conductor and a ground wire, a detachable connector to the receiver body pack and, preferably, a detachable connector to the sin-ear monitors. The invention provides for bidirectional communication between the audio base unit (receiver body pack) and the audio transducer system (in-ear monitors) and enables simultaneous and automatically configured DC power supply depending on the identified requirements.

Abstract: A handheld wireless microphone body may be connected to an assortment of microphone heads, providing compatibility between models from differing manufactures including accommodating differing attachment threads and electrical/audio output contact configurations without the need for hardware or software substitution.

Abstract: An external selector assembly, such as a spring-loaded bayonet style switch, is removably attached to a compatible electronic device, such as a wireless microphone transmitter intended to be worn by a performer. A contactless magnetic interface has at least one signal magnet in the external selector assembly and an array of one or more Hall sensors within the device housing. If mounted on the compatible electrical device, the external selector assembly enables the user limited control without requiring any physical changes to the compatible electrical device except for the mounting of the external selector assembly. The external selector assembly and contactless magnetic interface are compatible with a sealed housing (e.g. sealed to prevent dust ingress and/or water).

Abstract: Methods and devices are provided for the modular construction of a mixer-recorder and wireless receiving modules, where the receiving modules may be optionally attached directly to the mixer-recorder without the need for cabling between them and/or in combination with corded units placed in the vicinity of the mixer-recorder.

Abstract: A lavalier microphone has improved dynamic range. The lavalier microphone incorporates a pair of microphone transducer elements into the same housing or attached housings, with one of the microphone transducer elements being more sensitive to acoustic input than the other. The voltage signals from the respective transducer elements are processed and combined, resulting in a digital output audio signal with improved signal to noise both at lower and higher input acoustic levels.

Abstract: A method includes receiving, by a recording device, an indication of an initializing time and receiving, by the recording device, an indication of a timing pace. The method also includes maintaining, by the recording device, an updated current time based on the initializing time and the timing pace and sensing, via a sensor of the recording device, a condition. The method further includes storing, in memory of the recording device, an indication of the condition and an associated indication of the updated current time. The indication of the updated current time corresponds to when the condition was sensed by the sensor.

Abstract: A rotary fader apparatus includes a fader control knob that is directly attached to the rotor of a non-contact electrical motor. The apparatus may produce a fade effect based on the rotational position of the fader control knob and may be automated through signals to the motor. Such a rotary fader apparatus may be used, for example, in audio mixing applications to provide automated or manual rotary control of track fading. The motor may also be used to alter the feel of the movement of the fader control knob and/or provide tactile feedback in response to mixing parameters or signal properties.

Abstract: Methods and devices are provided for a wireless microphone network whereby robustness for reception of audio information transmitted by one or more wireless microphones is enhanced. The system incorporates a dual stage approach for collecting, transmitting and receiving audio information. In the first stage, audio information collected by one or more microphone modules is transmitted to a series of receiver base stations. In the second stage, information received at each base station is subsequently transmitted to a receiver hub that selects, blends and/or augments the information to produce a high quality representation for audio information that provides improved robustness and reliability with respect to the movement, physical placement or performance of each microphone module.

Abstract: A linear fader includes a slider that is configured to slide along a rail. The slider includes a magnet. The linear fader also includes a plurality of coils spaced along a length of the rail, one or more sensors configured to detect a position of the slider along the rail, and control circuitry operatively coupled to the plurality of coils and the one or more sensors. The control circuitry is configured to receive a signal corresponding to a first location of the slider from at least one of the one or more sensors, receive a desired location of the slider, and cause a first electrical current to pass through the plurality of coils, thereby generating a force on the slider in a direction toward the desired location.

Abstract: A multi-stage analog-to-digital conversion method and system use window functions and translation to match high gain frames of data to target frames of data. The technique selects window data packets for the output stream based the stage of data having the highest gain satisfying selection criteria, such as requiring a frame of data for the respective stage to satisfy a predetermined accuracy of fit value compared to a target frame of data for a zero gain stage.
