  • Publication number: 20230419058
    Abstract: A computer-implemented system and method for entity tracking and identification is provided. A tracker associated with an entity is tracked. Communication is continuously attempted between the tracker and a tracking device associated with an individual in custody of the entity. During one of the attempted communications, an absence of the tracker is determined by identifying a time of the attempted communication and applying a time threshold to the time for the attempted communication. The absence of the tracker is identified when no communication has been established with the tracking device within the time threshold. The entity is classified as missing when the absence of the tracker is determined.

  • Patent number: 9970853
    Abstract: An ultrasonic or acoustic viscosity sensor or viscometer is provided that can be used to accurately measure viscosity for fluid samples of less than 1 ?l in volume. Methods for measuring viscosity for fluid samples of less than 1 ?l in volume are also provided. The viscosity sensor and methods based thereon enable simultaneous measurement of bulk and dynamic (shear-rate dependent) viscosity of a non-Newtonian fluid. Bulk and dynamic viscosity of the non-Newtonian fluid can be measured simultaneously without separating constituents of the fluid, and thus distinguishing the effect of constituents on the viscosity. Dynamic viscosity of the non-Newtonian fluid can be estimated at varying shear rates, to study the deformability of the constituents of the fluid as a function of shear rate.
