Abstract: Embodiments provide a scheme for estimating an optimal read threshold voltage using a deep neural network (DNN) with reduced number of processing. A controller receives first and second program voltage (PV) levels associated with read operations on cells. The controller estimates first and second probability distribution parameter sets representing skew normal distributions of the first and second PV levels, respectively. The controller estimates an optimal read threshold voltage based on the first and second probability distribution parameter sets. The optimal read threshold voltage is a read threshold voltage such that first probability density function (PDF) value of the skew normal distribution of the first PV level is the same as the second PDF value of the skew normal distribution of the second PV level.

Abstract: A method and system for LDPC decoding method. In the method and system, an LDPC codeword is decoded using a quasi-cyclic matrix. A first message for variable nodes in a circulant column of the quasi-cyclic matrix and a second message for check nodes belonging to the circulant column are computed. Parity and syndrome are computed using the computed first and second messages. A bit error rate is calculated for both a first mode with no error in a parity portion of a codeword and a second mode with errors in the parity portion of the codeword.

Abstract: A facility for determining a heart rate of a person is described. The facility receives ultrasound data collected from the person at each of a number of times during a period of time, such as a sequence of B-mode images, or an M-mode image.

Abstract: The present disclosure provides a float valve motion detection device, a pot cover assembly and a pressure cooking appliance, the float valve motion detection device comprising: a float valve, a hollow inductance coil and a detection circuit. A valve core of the float valve is made of materials having permeability unequal to that of air. When the valve core is pushed by the pressure in a pot from a first position to a second position, the volume of the valve core in the hollow inductance coil changes, which changes the inductance of the hollow inductance coil. A detection circuit determines the position of the valve core by means of detecting the change in the inductance of the hollow inductance coil so as to determine whether it is safe to uncover at the current time.
