A mobile hearable device for communicating with a vehicle control system is described. The mobile hearable device includes a microphone, and a wireless transceiver configured as one of a near field magnetic induction (NFMI) transceiver and a near field electromagnetic induction (NFEMI) transceiver. The mobile hearable device includes a processor coupled to the transceiver and the microphone. The processor receives a location identifier via the transceiver from a location identification transmitter located in a vehicle, the location identification transmitter is configured as one of a NFMI transmitter and a NFEMI transmitter. If the processor receives a speech signal from a user of the mobile hearable device, it determines whether the speech signal includes an actuator control command and generates a control instruction comprising the actuator control command and the location identifier. The control instruction is transmitted to a vehicle control system and used to control an actuator in a vehicle dependent on the location of the person using the mobile hearable device.

Methods and apparatus to monitor a media presentation are disclosed. An example system includes a monitoring device to monitor a media presentation and generate research data identifying the media. A bridge device includes a housing dimensioned to receive the monitoring device, a receiver carried by the housing to receive a first audio signal via a wireless data connection from an audio source device using a wireless communication protocol, the first audio signal associated with the media. The bridge device includes an audio emitter to emit the audio signal for receipt by the monitoring device, and a transmitter to transmit the audio signal to an audio receiver device using the wireless communication protocol.

Systems, methods, and computer-readable media are disclosed for ring-shaped devices with combined Bluetooth and NFC antenna assemblies. In one embodiment, an example device may include an inner shell, an outer shell coupled to the inner shell, where the outer shell and inner shell together form a first side portion, a second side portion, and a lower portion of the ring-shaped device, a battery, and an antenna assembly that forms an upper portion of the ring-shaped device. The antenna assembly may include a metal substrate, a ferrite layer disposed on the metal substrate, and a metallic loop structure disposed on the ferrite layer.

The two-way communication system comprises a non-invasive and non-implanted system which allows for clear two-way communications. This system is generally comprised of a mouthpiece component, relay component, infrastructure communication device, an optional earpiece component, and an optional system control which may interface with the relay component.

An apparatus includes a housing and a circuit including an inductor and at least one capacitor in electrical communication with the inductor. The circuit has a resonance frequency and bounds a non-electrically-conductive region of the housing. The circuit is configured to be operable as an antenna.

A mounting system which includes a pocket for receiving a digital recorder or a wireless transmitter and a connector for connecting to the body of a microphone device, such as a hand held microphone. The pocket is made of a polyurethane foam and laminated with a four-way stretch nylon fabric which acts to grip the digital recorder or wireless transmitter to prevent it from sliding out of the pocket when handling the microphone. This pocket also covers the logo of the recorder or transmitter and any indicator lights or other indicators on the recorder or transmitter to make the digital recorder or wireless transmitter as visually low profile as possible. The mounting system provides unobstructed access to the microphone's on/off switch and indicator light. The four-way stretch nylon fabric helps retain the digital recorder or wireless transmitter near the top of the microphone.
