  • Patent number: 11136202
    Abstract: Electronic components are transferred from a source surface for supplying electronic components to a destination surface for receiving electronic components by an ejector device that is locatable at an ejection position for pushing an electronic component mounted on the source surface towards the destination surface. A support device that is locatable at a receiving position supports the electronic component that is pushed onto the destination surface. Further, a pre-transfer imaging device inspects the electronic component before it is transferred from the source surface and a post-transfer imaging device inspects the electronic component after it has been transferred onto the destination surface, wherein the pre-transfer and post-transfer imaging devices are located on opposite sides of the source and destination surfaces.

  • Patent number: 10684118
    Abstract: An apparatus for determining an orientation of a die mounted on a tape includes an imaging device, a light source and a conveying mechanism. The die is at least partially translucent and includes at least one orientation feature indicative of the orientation of the die. In use, the conveying mechanism conveys the tape to position the die at an inspection position between the imaging device and the light source. The light source projects light to the imaging device and the imaging device captures an image. The projected light from the light source passing through the die is obstructed by the at least one orientation feature of the die to cause the captured image to include an image of the at least one orientation feature, whereby the orientation of the die may be determined.

  • Patent number: 10014203
    Abstract: A semiconductor die pick and place device comprising a handing mechanism comprising a pick arm movable between a placement location and a pick-up location. A reference feature is located on the pick arm, and a light reflecting module is carried by the pick arm. The light reflecting module is operable to reflect an image of the reference feature to an image capturing module such that the reference feature appears to the light reflecting module to be in focus at a virtual position that is equivalent to a position at the pick-up location and/or the placement location.

  • Publication number: 20060136200
    Abstract: Embodiments of the invention provide a method and apparatus for adjusting the gain of conference users including a separate input gain for each user and an output gain for each user. The input gain may be determined in response to whether active audio is detected. Users may be classified as dominant speakers or passive participants. A separate class of input gain levels may be provided for dominant speakers (higher) and passive participants (lower). The input gain may be inversely proportional to user input energy level for dominant speakers. The output gain may be inversely proportional to user input energy level.
