  • 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.
    Type: Grant

  • Publication number: 20130319251
    Abstract: A method and system for noise cancellation in an air purifier is disclosed. The air purifier employed with a noise cancellation system comprises at least one microphone connected to the air purifier. At least one microprocessor programmable and adaptable to operate with a noise cancellation software is connected in a way to receive signals from the microphone placed inside or near the air purifier. A plurality of speakers connected to the microprocessor outputs the noise cancelled sound waves. The system is adaptable to operate with any conventional air purification filters and is capable to achieve optimum effectiveness without generating undesirable noise. The frequency of the noise cancelling sound waves matches the frequency of unwanted sound.

  • Publication number: 20060277457
    Abstract: An efficient, useful and practical way to integrate video into blogs such that the paradigm of text blogging can be applied to video. The user is provided the ability to post, revise, comment (and have others comment) on, syndicate and track video. Video is integrated into a blog environment such that blog-functions (e.g., posting, revising, commenting, quoting whole or sub-sets of video, syndication, tracking, etc.) are applied to video.

  • 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.
