Abstract: A federated learning method includes: providing importance parameters and performance parameters by client devices respectively to a central device, performing a training procedure by the central device, wherein the training procedure includes: selecting target devices from the client devices according to a priority order associated with the importance parameters, dividing the target devices into training groups according to a similarity of the performance parameters, notifying the target devices to perform iterations according to the training groups respectively to generate trained models, transmitting the trained models to the central device, and updating a global model based on the trained models, performing the training procedure again or outputting the global model to the client devices based on a convergence value of the global model and the number of times of performing the training procedure.

Abstract: A mutual-capacitance touch sensing device including a touch panel, a plurality of driving electrodes and a plurality of sensing electrodes is provided. The touch panel is substantially parallel to a reference plane. The driving and sensing electrodes are arranged to from a matrix including a plurality of sensing units. Each of the sensing units is associated with at least one driving electrode and at least one sensing electrode. A gap is formed between the at least one driving electrode and the at least one sensing electrodes. A projection length of the gap on the reference plane is longer than a total length of two diagonal lines in each of the sensing units.

Abstract: A touch sensing device including a touch sensing panel and P number of first sensors is provided. N sensing rows with a row spacing smaller than a predetermined touch diameter are defined on the touch sensing panel. The first sensors are for sensing whether the N sensing rows are touched. An n1-th sensing row and an n2-th sensing row share a same first sensor. The sensing rows directly neighboring to the n1-th and n2-th sensing rows respectively corresponds to the first sensors different from one another. N is an integer larger than 3; n1 and n2 are positive integers smaller than or equal to N. P is a positive integer smaller than N.

Abstract: A mutual capacitive touch panel includes electrodes arranged in N rows and multiple control channels. The electrodes arranged in N rows are formed on a same plane and are unconnected to one another. Each row of electrodes includes multiple unconnected electrodes. The control channels are formed on the same plane with the electrodes arranged in N rows. Each electrode corresponds to one control channel. A controller cooperating with the mutual capacitive touch panel sends driving signals and receives sensing results via the control channels.
