Head-mounted display systems and methods of operation that allow users to couple and decouple a portable electronic device such as a handheld portable electronic device with a separate head-mounted device (e.g., temporarily integrates the separate devices into a single unit) are disclosed. The portable electronic may be physically coupled to the head-mounted device such that the portable electronic device can be worn on the user's head. The portable electronic device may be operatively coupled to the head-mounted device such that the portable electronic device and head mounted device can communicate and operate with one another. Each device may be allowed to extend its features and/or services to the other device for the purpose of enhancing, increasing and/or eliminating redundant functions between the head-mounted device and the portable electronic device.

A wearable device includes first and second electronic modules, a connection module configured to electrically connect the first electronic module to the second electronic module, and a length adjusting module of which length is adjustable to bring the connection module in contact with a user. The length adjusting module comprises first and second fastening units configured to be assembled and disassembled and configured to be locked together in a fastened position when assembled. When the first and second fastening units are assembled, the first fastening unit is electrically connected to the second fastening unit and a length of the length adjusting module is adjusted.

A virtual shockwave creation system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the virtual shockwave creation system to generate, for each of multiple initial depth images, a respective shockwave image by applying a transformation function to the initial three-dimensional coordinates. The virtual shockwave creation system creates a warped shockwave video including a sequence of the generated warped shockwave images. The virtual shockwave creation system presents, via an image display, the warped shockwave video.

A characteristic of a blood product in a blood product container is determined. Using a smartphone, an image is acquired of a blood bag or tubing of the blood product container disposed in front of the smartphone. The image is processed using a processing circuit of the smartphone or a remote computer in wireless communication with the smartphone. The processing identifies a characteristic of the blood product from the image. A visual notification is generated on a display of the smartphone of the identified characteristic of the blood product.

The present subject matter relates to wireless VR devices. In an example implementation of the present subject matter, wireless VR devices are described. In an example, a wireless VR device includes a first array antenna disposed on a headband of the wireless VR device to communicate wirelessly. The wireless VR device also includes a second array antenna disposed on a display unit of the wireless VR device to wirelessly communicate with the docking station. In an example implementation, the first array antenna and the second array antenna have an omni-directional radiation pattern.

Various aspects include wearable audio devices enabling modular component attachment and detachment. In certain implementations, a wearable audio device includes: a headband for contacting a head of a user; an earpiece coupled with the headband for positioning proximate an ear of the user, the earpiece having an electro-acoustic transducer configured to output audio signals; and a slot configured to engage an electronic component, where the slot includes one or more snap-fit and/or friction-fit connectors for selectively engaging the electronic component.

A system for controlling a vehicle includes a programming device comprising an application for programming vehicle function settings of a vehicle. The programming device has a transmitter communicating the vehicle function settings of the vehicle. A vehicle receiver is disposed within the vehicle. The vehicle receiver receives the vehicle function settings. A vehicle is controller disposed within the vehicle. A helmet generates a helmet movement signal in response to sensing movement of the helmet. The helmet communicates a helmet identifier to the vehicle controller through the receiver in response to the helmet movement signal. The vehicle controller controls a vehicle function in response to the vehicle function settings.

A method of recording a state of an apheresis machine or a dialysis machine having a disposable component disposed thereon. The disposable component has tubing and a blood component bag. The disposable component is configured to be installed on the apheresis device or dialysis machine by a human operator. The method includes acquiring with a camera an image of a forward-facing external surface portion of the apheresis machine or dialysis machine and the tubing and the blood component bag of the disposable component. The image is acquired automatically without requiring user input. The method includes recording medical device information for the apheresis machine or dialysis machine comprising the image. The method includes generating a message comprising the image and transmitting the message comprising the image to a remote computer.

A head-mounted display device interfaces with a medical device configured to perform an invasive procedure on a patient. The display device includes a frame for mounting on a person's head, 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 input data relating to the medical device. The processing circuit retrieves from a memory an instruction relating to the medical device based on the input data and displays the instruction relating to the medical device on the display.
