  • Patent number: 11765533
    Abstract: The present invention provides a capacitive microphone such as a MEMS microphone with two capacitors. The signal output from the first capacitor is additive inverse of that from the second capacitor, and a total signal output is a difference between the two outputs. In at least one of the two capacitors, a movable or deflectable membrane/diaphragm moves in a lateral manner relative to the fixed capacitor plate, instead of moving toward/from the fixed plate. The squeeze film damping, and the noise are substantially avoided, and the performances of the microphone is significantly improved.

  • Patent number: 11757074
    Abstract: To extract light from a light-emitting diode (and thereby improve efficiency of the display), a microlens stack may be formed over the light-emitting diode. The microlens stack may include an array of microlenses that is covered by an additional single microlens. Having stacked microlenses in this way increases lens power without increasing the thickness of the display. The array of microlenses may be formed from an inorganic material whereas the additional single microlens may be formed from an organic material. The additional single microlens may conform to the upper surfaces of the array of microlenses. An additional low-index layer may be interposed between the light-emitting diode and the array of microlenses. A diffusive layer may be formed around the light-emitting diode to capture light emitted from the light-emitting diode sidewalls.

  • Patent number: 11735451
    Abstract: A support member system is described for association with an overhead transport system. The support member system provides a safety feature to the overhead transport system by which the overhead transport system is able to avoid damage to wafers that are contained within a wafer cassette that is unintentionally released by the overhead transport system. The support member system is able to prevent such released cassettes from impacting the ground or tools located under the overhead transport system. The support member system targets wafer cassettes that have dimensions which are different than the dimensions of wafer cassettes for which the overhead transport system was originally designed to transport. Stocker systems for receiving, storing and delivering different types of wafer cassettes are also described.
