Abstract: The disclosure provides a touch module, a touch display panel and a display device. Each touch electrode includes a plurality of electrode blocks arranged along an extending direction, and electrode blocks belonging to other touch electrodes are distributed in an area where at least part of all the electrode blocks are located, which makes full use of an interior area of a traditional touch pattern and increases a coupling area between the touch electrodes. When touch occurs, an amount of change in a mutual capacitance value between the touch electrodes will be significantly increased, thereby increasing touch sensitivity.

Abstract: Disclosed are an Internet of Things data transmission data and system. The method comprises a downlink transmission step: obtaining first downlink data delivered by an Internet of Things platform; parsing the first downlink data to obtain a target meter of a metering task and a forwarding priority in a first packet; obtaining second downlink data; adding the second downlink data to an asynchronous delivery queue according to the forwarding priority; and delivering the second downlink data to the target meter according to the asynchronous delivery queue, so that the target meter completes the metering task.

Abstract: The present disclosure provides a probabilistic decision engine for autonomous vehicles. Briefly described, one embodiment comprises taking a network connection matrix (based on maps and graph theory) and a cost matrix (with entries of the cost's mean values and probability distributions) as input and generates the probability distribution of optimal routes as output. The disclosed probabilistic decision engine comprises a stochastic network standardization module, a stochastic network decomposition module and a probabilistic optimization kernel. A deterministic network reduction method is first used to derive a standard reduced network, augmented by the stochastic network reduction. The standard network is then decomposed into a series of stochastic subnetworks by using the convolution, probability density function (PDF) shifting, and PDF reshaping techniques. A pure-analytical probabilistic solver is finally used to solve the stochastic optimization problem.

Abstract: An apparatus and a method for measuring a rotational angle of a sinking platform. The apparatus includes a sinking platform being a subject to be measured, suspension ropes and guide ropes connected to the sinking platform, a carriage assembled on the guide ropes, a gyroscope and a gyroscope signal radio transmitter mounted at an upper end of the carriage, and a tilt angle sensor and a radio signal reception processor mounted on the sinking platform. During running of the carriage, the gyroscope keeps measuring a pose of the carriage, and a measured signal is transmitted to the radio transmitter in a wired manner. The radio transmitter transmits a pose signal of the carriage during running to the radio signal reception processor in a wireless manner. A turning angle of the sinking platform in the y direction is accurately obtained by subtracting a pose of the carriage being located at the top of the guide ropes from a pose of the carriage being located at the bottom of the guide ropes.
