  • System for placing a label on an object, a method thereof and an effector for a robotic system
    Patent number: 11352161
    Abstract: A system for placing a label on an object comprising: a scanning module arranged to scan the object for a suitable label placement position based on predefined parameters associated with the label; a robotic controlled apparatus arranged to extract the label from a label substrate and move the label to be adjacent to the suitable label placement position; and, wherein the robotic controlled apparatus is further arranged to apply the label onto the suitable label placement position such that the label is adhere to the object.

  • Assembly for high-speed optical transmitter or receiver
    Patent number: 6869230
    Abstract: An optical assembly is provided that is capable of high speed operation using a vertical cavity laser such as a vertical cavity surface emitting laser (VCSEL). The optical assembly is configured to have a small form factor and uses an angled surface of an embedded fiber to internally reflect a beam from the VCSEL along the length of the fiber. The angled surface is coated to ensure that a small portion of the beam is transmitted through the fiber out of the angled surface into a monitoring diode. This geometry provides high coupling efficiency and facilitates direct active alignment between the fiber and the VCSEL.
