A system includes one or more optical emitters, a transceiver, and a body mountable device. The optical emitters emit light and are configured to be used in luminaires. The transceiver is coupled to receive input data from a data network and coupled to selectively modulate the optical emitters to transmit the optical data. Selectively modulating the optical emitters is in response to the input data. The body mountable device includes a photodetector coupled to receive the optical data and processing circuitry configured to initiate an action in response to receiving the optical data from the photodetector.

Systems, methods, devices, computer readable media, and other various embodiments are described for location management processes in wearable electronic devices. Performance of such devices is improved with reduced time to first fix of location operations in conjunction with low-power operations. In one embodiment, low-power circuitry manages high-speed circuitry and location circuitry to provide location assistance data from the high-speed circuitry to the low-power circuitry automatically on initiation of location fix operations as the high-speed circuitry and location circuitry are booted from low-power states. In some embodiments, the high-speed circuitry is returned to a low-power state prior to completion of a location fix and after capture of content associated with initiation of the location fix. In some embodiments, high-speed circuitry is booted after completion of a location fix to update location data associated with content.

A headset system comprising a headset and a base station. Each of said headset and base station comprises a transceiver configured to transmit radio signals between said headset and said base station according to a first wireless communication protocol, and each of said headset and base station further comprises a transceiver configured to transmit radio signals between said headset and said base station according to a second wireless communication protocol. At least one of said headset and said base station further comprises selecting means, such as a protocol selector configured to select one of said first and second wireless communication protocols for transmission of radio signals between said headset and said base station. The protocol selector is adapted to select the first wireless communication protocol for transmission of voice communication and the second wireless communication protocol for transmission of media content.

In one embodiment, a system includes, but is not limited to, an aviation head-mounted communication device including at least: a speaker, a physiological sensor configured to obtain physiological data, and a wireless communication interface; and a smartphone, a smartwatch, or tablet device wirelessly linked to the wireless communication interface and configured to receive the physiological data and output the physiological data on a display.

A user desires to complete a call utilizing a head-mounted display and a communication device. A call-initiating event is detected at the communication device. In response to the call-initiating event, an intended call recipient is identified utilizing the head-mounted display. A call is then initiated with the intended call recipient utilizing the communication device.

Accessory devices are described herein. An accessory device may include a receptacle for receiving an electronic device. The accessory device may include a case that covers the housing of the electronic device, or a folio that additionally includes a cover can conceal the display of the electronic device. Accessory devices described herein further include wireless circuitry used to communicate with wireless circuitry in the electronic device. The wireless circuitry can be used for various functions and features. For instance, the wireless circuitry in the accessory device can respond to authentication requests from the electronic device, and/or to send authentication requests to the electronic device. Further, the wireless circuitry in the accessory device can send information to the electronic device. Such information may include properties of the accessory device, or information stored on the accessory device that is presented on a display of the electronic device.

Systems and methods for managing temperatures of wearable device components are disclosed. In one aspects, a method includes determining a temperature of an electronic component of the wearable device, determining a rate of temperature change of the electronic component, and determining whether to increase or decrease a transmission rate limit of the electronic component based on the temperature and the rate, adjusting the transmission rate limit based on the determination, and limiting a rate of transmission of the electronic component based on the adjusted transmission rate limit.

A system including image capture eyewear, a processor, and a memory. The image capture eyewear includes a support structure, a selector connected to the support structure, a display system (e.g., LEDs or a display) connected to the support structure to distinctly display assignable recipient markers, and a camera connected to the support structure to capture an image of a scene. The processor executes programming in the memory to assign recipients to the assignable recipient markers, receive a captured image of the scene, receive an indicator associated with the assignable recipient markers distinctly displayed at the time the image of the scene was captured, and transmit the captured image to the recipient assigned to the distinctly displayed assignable recipient markers.

A system includes an antenna, an impedance measurement circuit, an impedance tuning circuit, and a controller. The impedance measurement circuit can include a test current source that conveys a test current through the antenna, and a voltage sensor that measure a voltage across the antenna while the test current is conveyed through the antenna. The impedance tuning circuit can be coupled to the antenna leads and can include one or more reactive elements that can be selectively coupled to the antenna, or otherwise adjusted, to effect adjustment of the impedance connected to the antenna. The controller can: (i) use the impedance measurement circuit to obtain a measurement indicative of an impedance of the antenna; (ii) determine an adjustment to the impedance tuning circuit based on the obtained measurement; and (iii) cause the impedance tuning circuit to make the determined adjustment.

A head-mounted display device for interface with a blood processing machine using a disposable component having tubing and a blood component receptacle includes a frame configured to be mounted on a person's head and configured to hold a lens in front of an eye of the person. The display device includes a display, a wireless transceiver configured to communicate with a network, and a processing circuit. The processing circuit is coupled to the frame, the display and the wireless transceiver and receives instructions for training the person how to use the blood processing machine. The processing circuit overlays indicators, text, highlighting and/or icons on the blood processing machine as seen from a field of view of the person based on the instructions to train the person in using the blood processing machine.
