Abstract: Methods and devices are provided for a real time spectrum analyzer (RTSA) to run live on a wireless microphone receiver system whereby text labelling, graphical identifiers and background-shading may be added to the display to allow users to more easily differentiate frequency regions that are likely to be affected by RF emissions from external devices that may influence available the signal to noise ratio for a wireless microphone transmitter and receiver pair. Frequency bands allocated to DTV channels operating within the configurable frequency range of the receiver transmitter pair are identified on a live RTSA scan displayed on the receiver display.

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: 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 handheld wireless microphone has a receiving coil used for induction charging by placing the microphone vertically into a charging holster in a charging station. The receiving coil is located concentrically with the charging coil wound around the charging holster and provides effective magnetic coupling. Ferrite plates are used to enhance inductive coupling and minimize interference from metal components in the microphone. Due to the symmetry of the charging holster and transmitting coil, the user need not concern themselves with the rotary orientation of the microphone when placing it vertically into the holster.

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. A reversible head connection adapter is fastened to the microphone body with screws. A removable main body sleeve covers push buttons for a first user interface to protect against activation by the talent when performing. A secondary user interface is covered by an interchangeable control ring which allows limited control from the exterior while the microphone is active.

Abstract: Methods and devices are provided for the construction of an electronic device, such as a digital wireless transmitter, containing an e-paper display that is sensitive to changes in the configuration of the power supply for the device. This display provides up-to-date accurate information to a user, even after a power disconnect.

Abstract: A wireless RF connection provides relocatable transmitter and/or receiver antennas utilizing digital fiber optic connections to provide improved resilience of relocatable RF antennas. Improved robustness against suboptimal performance of various optical components is realized by the introduction of serial, bit stream transmission of in-phase and quadrature modulation data (I, Q data).

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 handheld wireless microphone has improved resilience against intermittent dropouts due to the placement of hands on the body of the handheld wireless microphone. A robust, dipole RF antenna is provided in the body of the handheld microphone. One antenna element is a conductive cone or truncated cone at the bottom of the microphone body, which is surrounded by a conductive cup and an insulated gap layer to form a capacitive coupling configuration that mitigates interference of RF radiation by human flesh. The other antenna element is conductive and serves as the frame of the microphone body.

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: Methods and devices are provided whereby deficiencies in the impedance of a cable connecting an electric guitar and a wireless transmitter or other audio device may be electronically corrected, according to user preferences. User settings may be saved and recalled as needed from a program interface that serially communicates with electronics controlling the behavior of the cable.

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.
