  • Patent number: 10663531
    Abstract: An apparatus detects a short of a class-D amplifier. A pulse detector detects an output PWM pulse exceeds a predetermined width and a controller differentiates whether the pulse width exceeding is caused by a short or by a large digital input signal occurring during normal operation based on an expected level of the digital input signal to a level of the digital input signal when the pulse width exceeds the predetermined width. The expected level is dynamically obtained in response to one or more previous PWM pulses exceeding the predetermined width during the normal operation and may be selected based on an amount the pulse exceeds the predetermined width. A lookup table of predetermined levels, selected based on impedance of a load, provides the expected level if the expected level has not yet been dynamically obtained when the pulse width exceeds.

  • Publication number: 20200140856
    Abstract: A cell model for in vitro evaluation of compound-induced skin sensitization and a constructing method therefor. The method for constructing the cell model comprises the steps of: designing and constructing an sgRNA expression vector based on CRISPR/Cas9 vector system; designing and constructing a homologous recombinant vector capable of knocking a reporter gene linked to a self-cleaving peptide sequence into a specific site of the expression frame of the HMOX1 gene; co-transfecting the homologous recombinant vector, an hCas9 plasmid and the sgRNA expression vector into a cell, and carrying out monoclonal expansion to obtain the cell model. The present invention obtains a HaCaT cell model in which a luciferase gene is knocked in before the stop codon of the HMOX1 gene by combination of CRISPR/CAS9 and a monoclonal cell technique. The cell model realizes synchronous expression of the luciferase gene and the HMOX1 gene, thereby effectively distinguishing sensitizing compounds from non-sensitizing compounds.
