  • Patent number: 11355397
    Abstract: A method for fabricating a three-dimensional (3D) static random-access memory (SRAM) architecture using catalyst influenced chemical etching (CICE). Utilizing CICE, semiconductor fins can be etched with no etch taper, smooth sidewalls and no maximum height limitation. CICE enables stacking of as many nanosheet layers a desired and also enables a 3D stacked architecture for SRAM cells. Furthermore, CICE can be used to etch silicon waveguides thereby creating waveguides with smooth sidewalls to improve transmission efficiency and, for photon-based quantum circuits, to eliminate charge fluctuations that may affect photon indistinguishability.

  • Patent number: 11337870
    Abstract: A self-propelled emergency stretcher includes an elongate frame having a set of wheels a track drive unit mounted thereto. The set of wheels includes first wheels at a front end of the frame and second wheels at a rear end of the frame, and the track drive unit is mounted between the first wheels and the second wheels. A plurality of actuators is configured to raise and lower the first wheels and the second wheels relative to the frame, so as to selectively switch the emergency stretcher between a self-propelled configuration and a manually-propelled configuration. In the self-propelled configuration the first wheels and the second wheels are out of contact with a ground surface below the emergency stretcher and the track drive unit is in contact with the ground surface. In the manually-propelled configuration the first wheels and the second wheels are in contact with the ground surface and the track drive unit is out of contact with the ground surface.

  • Publication number: 20210263389
    Abstract: Aspects of the present disclosure describe optical phased array structures and devices in which hyperbolic phase envelopes are employed to create focusing and diverging emissions in one and two dimensions. Tuning the phase fronts moves focal point spot in depth and across the array. Grating emitters are also used to emit light upward (out of plane). Adjusting the period of the gratings along the light propagation direction results in focusing the light emitted from the gratings. Changes in the operating wavelengths employed moves the focal spot along the emitters.

  • Publication number: 20210218638
    Abstract: Systems, methods, and computer-readable media for flow stitching network traffic flow segments at a middlebox in a network environment. In some embodiments, flow records of traffic flow segments at a middlebox in a network environment are collected. The flow records can include transaction identifiers assigned to the traffic flow segments. Sources and destinations of the traffic flow segments with respect to the middlebox can be identified using the flow records. Further, the traffic flow segments can be stitched together to form a plurality of stitched traffic flows at the middlebox based on the transaction identifiers and the sources and destinations of the traffic flow segments in the network environment with respect to the middlebox. A configuration of the middlebox operating in the network environment can be identified based on the stitched traffic flows at the middlebox in the network environment.
