Patent number: 11992955Abstract: A spearing end effector for a robotic spearing device capturing and sorting a selected item from a mass of items and having a robotic manipulator with the spearing end effector mounted at an end thereof. The robotic spearing device comprises: a spearing end effector body; a spike; a linear actuator having the spike mounted thereon; and a propeller. The spike is configurable between a retracted configuration where it is entirely located inside the spearing end effector body and an extended configuration where it extends outwardly from therefrom. The spike is engageable to the selected item when configured in the extended configuration. The linear actuator is movable to configure the spike between the retracted configuration and the extended configuration. The propeller is selectively activatable to propel the selected item in a propelling direction during an ejection of the selected item from the spearing end effector.Type: GrantFiled: April 23, 2021Date of Patent: May 28, 2024Assignee: Waste Robotics Inc.Inventors: Eric Camirand, Michel Laforest, Pier Grenon, Nicolas Belanger, Jean-Pierre Thibodeau, Frederic Martin

Patent number: 9197354Abstract: The present disclosure relates to concatenated optical spectrum transmission systems and methods that allocate optical spectrum of groups of channels to reduce or eliminate deadbands or guardbands (i.e., unused optical spectrum) between channels. The concatenated optical spectrum transmission systems and methods include various techniques for using optical spectrum such as over the C-band or any other frequency bands. In particular, the concatenated optical spectrum transmission systems and methods provide a balance between fixed channel systems such as provided for by the International Telecommunication Union (ITU) and a more flexible system enabled by coherent optical detection. In an exemplary embodiment, the concatenated optical spectrum transmission systems and methods may utilize a Wavelength Selective Switch (WSS) and a plurality of moderate Common Mode Rejection Ratio (CMRR) coherent receivers in combination to achieve a concatenated optical spectrum.Type: GrantFiled: August 26, 2011Date of Patent: November 24, 2015Assignee: Ciena CorporationInventors: David Boertjes, Michel Belanger
