    Abstract: A head-mountable device can operate in concert with one or more optical assemblies thereof to provide multiple users with shared experiences and content enjoyment. Such operations can be facilitated by a connection between the head-mountable device and one or both of its optical assemblies to allow different users to receive content. Such a connection can be made possible by a communication link that directly and/or physically connects the head-mountable device and one or both of its optical assemblies when the one or both of the optical assemblies is removed from the head-mountable device for operation by a separate user. The ability to provide multiple outputs on separate components allows separate users to participate in a shared experience.

  • Patent number: 12249295
    Abstract: A semiconductor device includes a gradation voltage generation circuit, output amplifier circuits, a drive control circuit, and a delay time measurement circuit. The gradation voltage generation circuit converts, according to a load signal, pixel data pieces into gradation voltages and outputs the gradation voltages. The output amplifier circuits generate drive signals by individually amplifying the gradation voltages, and output the drive signals to data lines. The drive control circuit outputs the load signal to the gradation voltage generation circuit according to a horizontal synchronization signal. The delay time measurement circuit obtains, as a measured delay time, a time from receiving the measurement start signal until a voltage value of the drive signal outputted from one of the output amplifier circuits exceeds a predetermined threshold voltage. The drive control circuit shifts a timing of outputting the load signal by a difference between the measured delay time and a reference delay time.
