  • ULTRASOUND DEVICE INCLUDING A DETACHABLE ACOUSTIC COUPLING PAD
    Publication number: 20200289089
    Abstract: A device obtains ultrasound signals with ultrasound sensors without using ultrasound coupling gels on the face of the device. One such device includes an acoustic coupling pad that is placed on the ultrasound sensors. The acoustic coupling pad replaces conventional water-based ultrasound sensing gels to obviate the need for using such gels that may cause an electrical short circuit between electrode leads of electrocardiogram sensors positioned adjacent to the ultrasound sensors in the face of the device.

  • Systems and methods of measuring quality of video surveillance infrastructure
    Patent number: 10750126
    Abstract: One or more key performance indicators are necessary to properly measure the health of video surveillance applications and the supporting infrastructure. Some of the key performance indicators include: Video Path Uptime (VPU), Video Stream Delivery Index (VSDI), and, Video Retention Compliance (VRC). From these metrics, it is possible to calibrate whether a surveillance infrastructure is operating properly. These metrics can be used to properly alert video network administrators of problems that are actually affecting the video surveillance application. It is also possible to use these metrics to build better analytics to determine root cause of problems as well as build prediction models for potential problems before they occur.

  • Facilitating lane-splitting by motorcycles
    Patent number: 10698404
    Abstract: A controller of a motorcycle determines that the motorcycle is lane-splitting. The controller transmits a notification to vehicles in proximity to the motorcycle. In response to the notifications, the vehicles facilitate lane-splitting by the motorcycle. In particular the vehicles may flash lights to communicate that the vehicle has received the notification and will facilitate lane-splitting. The vehicles may facilitate lane-splitting by refraining from performing lane changes. The vehicles may further notify the motorcycle if lane changes are needed and the motorcycle controller may provide an alert to a rider.
