Publication number: 20210080484Abstract: Infrared (IR) vibrational scattering scanning near-field optical microscopy (s-SNOM) has advanced to become a powerful nanoimaging and spectroscopy technique with applications ranging from biological to quantum materials. However, full spatiospectral s-SNOM continues to be challenged by long measurement times and drift during the acquisition of large associated datasets. Various embodiments provide for a novel approach of computational spatiospectral s-SNOM by transforming the basis from the stationary frame into the rotating frame of the IR carrier frequency. Some embodiments see acceleration of IR s-SNOM data collection by a factor of 10 or more in combination with prior knowledge of the electronic or vibrational resonances to be probed, the IR source excitation spectrum, and other general sample characteristics.Type: ApplicationFiled: November 25, 2020Publication date: March 18, 2021Inventors: Rafael Piestun, Simon Labouesse, Markus B.

Patent number: 10776794Abstract: A mechanism for customer service with security and privacy is provided. In a support service scenario for products or services, a determination is made based on an interaction with a customer that additional verification is needed. An authentication code is communicated to the customer via a mode chosen by the customer. At the same time, a hash of the authentication code is stored along with session and customer details. The customer is prompted to provide the authentication code and a hash of the provided authentication code is compared to the hash of the authentication code that was stored with the session and customer details. If the hashes match, it can be presumed that the agent is communicating with the correct customer and customer details are revealed. If the hashes do not match, the agent does not see any private customer details.Type: GrantFiled: June 5, 2017Date of Patent: September 15, 2020Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Jawad Ahmed Ibrahim Katib, Arun R.

Publication number: 20200280428Abstract: Examples described herein relate to a physical layer interface device with an interface to a medium and a link controller. The link controller can attempt to form a link with another device through the interface. Based on failure to achieve link using a last successful configuration, an attempt to form a link with another device through the interface can include interleaving use of an IEEE 802.3 compatible auto-negotiation process with at least one attempt to form a link using a non-auto-negotiated mode. Based on failure to achieve link with the another device using any available link speed mode and forward error correction (FEC) scheme, an attempt is made using IEEE 802.3 compatible auto-negotiation without use of Next Pages.Type: ApplicationFiled: February 4, 2020Publication date: September 3, 2020Inventors: Istvan KOVACS, Samuel A.

Patent number: 10605138Abstract: An exemplary embodiment includes a blending chamber having a urea inlet, a blending chamber gas inlet, and a blending chamber outlet. A urea source provides a pressurized urea solution to the urea inlet at a urea injection pressure, and a pressurized gas source transmits pressurized gas to the blending chamber gas inlet via a passageway. The passageway is configured to decrease pressure of the pressurized gas transmitted along its length from a first pressure of gas received from the pressurized gas source to a second pressure of gas provided to the blending chamber gas inlet. The first pressure of gas received from the pressurized gas source is greater than the urea injection pressure and the second pressure of gas provided to the blending chamber gas inlet is less than the urea injection pressure.Type: GrantFiled: February 13, 2018Date of Patent: March 31, 2020Assignee: Cummins Emission Solutions Inc.Inventors: George L.
