Efficient detection of ransomware attacks within a backup storage environment
Described is a system that efficiently detects ransomware attacks within a storage environment. The system may perform a specialized validation by comparing a sampling of backup data obtained from a storage environment with a sampling of data maintained by a specialized validation database.

Scalable feedback control of single-photon sources for photonic quantum technologies
Typically, quantum systems are very sensitive to environmental fluctuations, and diagnosing errors via measurements causes unavoidable perturbations. Here, an in situ frequency-locking technique monitors and corrects frequency variations in single-photon sources based on resonators. By using the classical laser fields used for photon generation as probes to diagnose variations in the resonator frequency, the system applies feedback control to correct photon frequency errors in parallel to the optical quantum computation without disturbing the physical qubit. Our technique can be implemented on a silicon photonic device and with sub 1 pm frequency stabilization in the presence of applied environmental noise, corresponding to a fractional frequency drift of <1% of a photon linewidth. These methods can be used for feedback-controlled quantum state engineering. By distributing a single local oscillator across a one or more chips, our approach enables frequency locking of many single photon sources for large-scale photonic quantum technologies. |

Systems and methods for managing building signature intelligent electronic devices
A method for evaluating a building signature operational model (BSOM) associated with a building signature intelligent electronic device (BSIED) includes processing building signature operational data (BSOD) on a cloud-connected central processing unit to identify the BSIED from which the BSOD was received, and to determine if a current BSOM associated with the BSIED, and used by the BSIED to generate the BSOD, needs to be updated. In response to determining that the current BSOM needs to be updated, a new BSOM is selected for the BSIED from a BSOM library based, at least in part, on one or more characteristics associated with the BSIED. The new BSOM is transmitted to the BSIED for installation on the BSIED. |

Windband silencer with means to reduce cross-wind pressure differential
A windband for an exhaust fan system. The windband comprises an elongate housing receivable about a exit nozzle of the exhaust fan system, an air inducer formed from a perforated material and positioned adjacent the bottom portion of the elongate housing, and a discharge sleeve positioned adjacent and secured to the top portion of the elongate housing. The discharge sleeve is formed from a perforated material and forms a passageway through which gas from the nozzle and induced ambient air passing through the elongate housing are discharged. The perforated air inducer and discharge sleeve together assist in the minimization of a pressure differential between an upwind side of the windband and a downwind side of the windband when the windband is subjected to wind striking the windband at an angle. |

Orifice holder mounting system for gas cooktop
A compact non-rotational mounting feature or mechanism is employed for mounting an orifice holder to a support member below a cooktop of a gas cooking appliance. More specifically, the holder and support member include interengaging polygonal structure, such as a key-shaped anti-rotational peg and hole combination, allowing the holder to be initially mated with the support member in a manner which prevents relative rotation and assuring that the holder is appropriately positioned for proper alignment of various gas burner components, such as an orifice, a gas line, electrode, flame spreader and other burner related structure. Upon exacting the positioning of the holder relative to the support member, the holder to fixed in position by a mechanical fastener. |
