In artificial neural networks, and other similar applications, there is typically a large amount of data involved that is considered sparse data. Due to the large size of the data involved in such applications, it is helpful to compress the data to save bandwidth resources when transmitting the data and save memory resources when storing the data. Introduced herein is a compression technique that selects elements with significant values from data and restructures them into a structured sparse format. By generating metadata that enforces the structured sparse format and organizing the data according to the metadata, the introduced technique not only reduces the size of the data but also consistently places the data in a particular format. As such, hardware can be simplified and optimized to process the data much faster and much more efficiently than the conventional compression techniques that rely on a non-structured sparsity format. |

Non-three-phase fault isolation and restoration systems
A smart switch allows distributed generators to “ride through” non-three-phase faults by very quickly detecting a non-three-phase phase fault, locating the fault, identifying the “responsive sectionalizer switches” that will be involved in clearing or isolating the fault, and selecting one of the responsive sectionalizer switches to direct back-feed tie switch operations. The responsive sectionalizer switches trip only the faulted phase(s), and the selected sectionalizer switch instructs a back-feed tie switch to close to back-feed the distributed generators prior to conducting the typical fault response operation. This typically occurs within about three cycles, and is completed before the normal fault clearing and isolation procedures, which momentarily disconnect all three phases to the distributed generators from the normally connected feeder breaker. The looped connection to an alternate feeder breaker during these operations allows the distributed generators to “ride through” the normal fault clearing and isolation procedures. |

Vehicle sound emission control
A speed of a target vehicle can be detected. A difference in host vehicle speed and the speed of the target vehicle is determined. A target frequency is specified for a sound to be received at the target vehicle. A sending frequency is determined for the sound based on the target frequency and the difference in host vehicle speed and target vehicle speed. The sound is transmitted at the sending frequency. |

System and method for real-time assessment of traffic stream flow characteristics
The present disclosure relates to a system and method for updating traffic-related infrastructure. The method includes determining average traffic stream speed and average traffic density over a segment of a highway. The method further includes determining, upon analysis of the determined average traffic stream speed and average traffic density over a segment of a highway, an appropriate action in order to update the infrastructure. |

Wearable personal or public safety device
Most embodiments of the invention are for a public safety device that is typically worn and may collect various types of information from stimuli, whether from the environment or, if worn, then also from the body wearing the device. The device is typically in constant communication with at least one remote server. In certain embodiments, the device may communicate instrument data to be processed by a remote computing device to detect a combative situation and relay an emergency signal. In other embodiments, based on certain input from the various instruments measuring the stimuli, the device itself may detect a combative situation and transmit an emergency signal. |

Signal device for maritime distress rescue and surveillance device for maritime distress rescue
A signal device for maritime distress rescue and a surveillance device for maritime distress rescue are provided. The signal device for maritime distress rescue which is carried by a user aboard a vessel may include a first communicator configured to communicate with a surveillance device for maritime distress rescue of the vessel, a first position detector configured to generate first position information of the signal device at a predetermined time interval, and a first controller configured to receive second position information of the surveillance device from the surveillance device at a predetermined time interval and determine whether the first position information is within a safe area of the vessel that is set on the basis of the second position information. Accordingly, when a distress occurs, it is possible to transmit a distress signal without operating a switch while minimizing power consumption of the signal device. |

Identifying smoke within a vehicle and generating a response thereto
System, methods, and other embodiments described herein relate to improving the safety of a vehicle in relation to occurrences of smoke and fire. In one embodiment, a method includes acquiring, from a radar of a subject vehicle, radar data about a passenger cabin of the subject vehicle. The method includes determining a current state of the passenger cabin according to the radar data. The method includes, responsive to identifying that the current state indicates smoke is present within the passenger cabin, controlling the subject vehicle to generate a response to the smoke. |

Dual function strap for resonating elements and ultra high frequency antennas
A combined EAS and RFID circuit includes an HF coil antenna, a UHF tuning loop, and an RFID chip coupled to a strap that includes a first coupling area and a second coupling area. The coil ends of the HF coil antenna are configured to capacitively and/or conductively couple to one or both of the first coupling area or second coupling area of the strap. The HF coil antenna can include a gap between turns for non-interfering placement of the UHF tuning loop. The EAS circuit can be deactivating upon application of a field at the resonant frequency of sufficient intensity to cause the breakdown voltage to be exceeded between a coil end and coupling area. The threshold breakdown voltage between a coil end and a coupling area can be reduced by laser ablation treatment of a conductive surface of one or both of the coil end or coupling area. |

Cloud-connected occupancy lights and status indication
Methods and systems for providing an availability status associated with a facility. One system includes a visual indicator associated with a facility subsystem of the facility and a sensor configured to detect data associated with the facility subsystem. The system also includes a controller communicatively coupled to the visual indicator and the sensor. The controller is configured to receive a data from the sensor. The controller is also configured to determine a current availability status associated with the facility subsystem based on the data received from the sensor. The controller is also configured to control the visual indicator to indicate the current availability status associated with the facility subsystem. |
