In distributedsensor fusion systems, each of the local sensors has its own tracker processing local measurements for measurement-to-track association and state estimation. Only the processed data, local tracks (LT) comprising state vector estimates and their covariance matrices are transmitted to the fusion center (FC). In this work, a multi-object hybrid probabilistic information matrix fusion (MO-HPIMF) is derived taking into account all association hypotheses. In MO-HPIMF, the association carried out is between the FC track states (prediction) and the LT state estimates from local sensors. When having a large number of objects and sensors in fusion, only the m-best FC-track-to-LT association hypotheses should be incorporated in MO-HPIMF to reduce the computational complexity. A Sequential m-best 2-D method is used for solving the multidimensional assignment problem in this work. It is shown in the simulations that MO-HPIMF can successfully track all targets of interest and is superior to track-to-track fusion (T2TF, a commonly used approach in distributedsensor fusion system) which relies on hard association decisions.

This paper presents a humidity sensor consisting of a two-port piezoelectric bulk wave resonator and a uniform layer of graphene oxide (GO) film, aiming for the applications of human-machine interaction. With the help of the hydrophilic GO film, the sensor possesses high sensitivity (195 Hz/%RH with an operating frequency of 10.5 MHz) and low hysteresis (less than 3%RH) to environmental humidity changes. Meanwhile, the humidity response of the sensor is rapid, highly repeatable and stable, which endows the sensor a fast and accurate response to the approach of a human finger. Moreover, by leveraging the different reactions of the sensor to the finger approaching and staying for various lengths of time, the noncontact information input can be realized in the form of Morse code.
