Abstract: Embodiments are directed towards establishing a network between mobile devices, an automobile head unit, and a plurality of automobile accessories. A user utilizes a user interface on a mobile device to send an accessory access request to the head unit. The head unit receives the request and determines if the mobile device is authentic. If authentic, the head unit determines if the mobile device has the proper permissions to perform the requested access of the accessory. If permitted, the head unit generates and sends control commands to the accessory or obtains the requested accessory data and provides it to the mobile device.

Abstract: The present disclosure relates to a light emitting device that can improve design of emitted light. A communication substrate is provided with an LED indicator which emits light. A light guiding plate has a concave surface portion which is a concave surface to cover the LED indicator, and receives the light from the LED indicator using the concave surface portion. A storage case stores the communication substrate and the light guiding plate in a state where a part of the light guiding plate is exposed. The light guiding plate allows the light from the LED indicator to penetrate to a part of the light guiding plate exposed from the storage case by diffusing the light received using the concave surface portion. For example, the present disclosure is applicable to the light emitting device that emits light using an LED or the like.

Abstract: Embodiments are directed towards establishing a network connection between a mobile device and an automobile head unit. A user of the mobile device interacts with a user interface on the mobile device to establish the connection with the head unit. If authorized, the head unit disconnects a currently connected device if the connection is to be via classic Bluetooth protocols. If the head unit has reached a maximum number of registered mobile devices, then the head unit sends a request to the mobile device for a selection of which currently registered mobile devices are to be unregistered. The head unit registers the mobile device with the head unit and establishes the connection between the mobile device and the head unit via classic Bluetooth protocols or Bluetooth Low Energy protocols depending on the type of connection request.
