  • Patent number: 11453423
    Abstract: A system for railroad directive management is presented. The system can receive a myriad of data related to a directive, track segments, and/or vehicle events on the track and/or track segments. Vehicle- and/or event-specific data can be compared with one or more thresholds, including force thresholds, temporal thresholds, environmental thresholds, and/or event thresholds to determine whether and what kind of directive modification should be instantiated. Specialized algorithms can be implemented to trace vehicle paths along the track to determine whether directive-related segments are traversed, and specialized clustering algorithms can be utilized to cluster data unique to a particular segment on a per-segment basis. The system can be integrated with existing track infrastructure and can further generate alerts to notify coupled systems and/or personnel of directives and/or modification thereof.

  • Patent number: 11347355
    Abstract: Acoustic touch and/or force sensing system architectures and methods for acoustic touch and/or force sensing can be used to detect a position of an object touching a surface and an amount of force applied to the surface by the object. The position and/or an applied force can be determined using time-of-flight (TOF) techniques, for example. Acoustic touch sensing can utilize transducers (e.g., piezoelectric) to simultaneously transmit ultrasonic waves along a surface and through a thickness of a deformable material. The location of the object and the applied force can be determined based on the amount of time elapsing between the transmission of the waves and receipt of the reflected waves. In some examples, an acoustic touch sensing system can be insensitive to water contact on the device surface, and thus acoustic touch sensing can be used for touch sensing in devices that may become wet or fully submerged in water.

  • Patent number: 11090985
    Abstract: The invention relates to a method and an apparatus for determination of the wear on at least one tire of a vehicle, wherein the vehicle has a tire pressure monitoring system, consisting of a pressure sensor, a transmission unit and a reception unit, as well as a computer unit and a data memory having a database. Proceeding from a circumference of the tire (5) defined by the tire manufacturer and thereby a mantle surface having a length L=2?r, wherein r is the radius of the tire (5), the radius decreases during corresponding wear, and thereby the length of the mantle surface also decreases. The length of the flat pattern of a new tire is therefore greater, in terms of length, than the length of the flat pattern of a used tire. This is determined by a sensor (4), the value of which is transmitted by a first module (2) to a second module (3), which is fixed in place. There, the value L is calculated and compared with data in a database and evaluated.
