  • Patent number: 11960085
    Abstract: A manufacturing method of a waveguide and a head mounted display device having the waveguide are provided. The head mounted display device includes a display unit, a first waveguide and a second waveguide. The display unit is configured to provide an image beam. The first waveguide is located between the display unit and the second waveguide. The first waveguide is configured to transmit the image beam to the second waveguide and adjust a light shape of the image beam to maintain a field angle and expand a pupil in a single dimension. The second waveguide is configured to transmit the image beam to outside of the head mounted display device, and the second waveguide can extend a light transmission path and provide a uniform image beam.

  • Publication number: 20240088246
    Abstract: Various embodiments of the present application are directed towards a control gate layout to improve an etch process window for word lines. In some embodiments, an integrated chip comprises a memory array, an erase gate, a word line, and a control gate. The memory array comprises a plurality of cells in a plurality of rows and a plurality of columns. The erase gate and the word line are elongated in parallel along a row of the memory array. The control gate is elongated along the row and is between and borders the erase gate and the word line. Further, the control gate has a pad region protruding towards the erase gate and the word line. Because the pad region protrudes towards the erase gate and the word line, a width of the pad region is spread between word-line and erase-gate sides of the control gate.

  • Publication number: 20240015700
    Abstract: The invention provides a method for multi-paging of a user equipment (UE) in a network; the network may be a wireless cellular network, and may comprise a plurality of cells. The method may be executed by the UE, and may comprise a multi-paging procedure. The multi-paging procedure may comprise: when the UE camps on a serving cell of the plurality of cells, checking whether a non-serving cell paging message is received on a non-serving cell of the plurality of cells, with the non-serving cell being different from the serving cell.

  • Patent number: 9681316
    Abstract: A communications apparatus includes at least two cellular system radio transceivers capable of simultaneously performing transmitting/receiving radio activities in two cellular networks and a control entity. The control entity is coupled to the cellular system radio transceivers, collects radio activity information of the cellular system radio transceivers, determines whether interference will occur or is occurring and which cellular system radio transceiver is an aggressor transceiver and which cellular system radio transceiver is a victim transceiver when the interference occurs according to the radio activity information, and further determines control information according to the radio activity information for controlling the aggressor transceiver or the victim transceiver to mitigate the interference. The aggressor transceiver is the cellular system radio transceiver having the transmitting radio activity that will interfere or interferes with the receiving radio activity of the victim transceiver.
