Abstract: A violation checking method includes generating a violation log report for a design, classifying violation logs in the violation log report into high-risk logs and low-risk logs by a machine learning model, reviewing the high-risk logs, and modifying the design if at least one bug is identified in the high-risk logs.

Abstract: A control knob for controlling operation of a machine, the control knob including: an attachment surface configured for attaching the control knob to a surface of the machine; a display member comprising an electronic display module disposed thereon; a motion sensor configured for sensing motion of the user's hand, said sensor being operably-connected to the display member such that, responsive to the motion sensor sensing motion of the user's hand, the display member is configured to switch operation from a sleep mode into an active mode; an operational mode display controller for controlling display of operational modes of the machine upon the electronic display module, said operational mode display controller being configured for rotational movement around the electronic display module amongst a plurality of rotational positions, said operational mode display controller being operably connected with the electronic display module such that, responsive to the rotational movement of the operational mode displ

Abstract: A speed control switch includes a base. An upper end of the base is provided with a switch assembly. A side of the base is provided with a PCB board and a slide terminal. The PCB board is provided with a first contact plate. The slide terminal is slidably connected with the first contact plate. The base is provided with a trigger assembly for driving the slide terminal to slide along the first contact plate and to close the switch assembly. The speed control switch can regulate the speed of a motor precisely. The structure is compact to reduce the size of the switch, so that it is convenient for operation.

Abstract: A circuit 100 for determining the polarity of an input sequence of pulses 200 or 300 applied to input 102 by digitally determining the polarity of a predetermined number of pulses of the input sequence of pulses using the digital polarity determinator 130 and, dependent on the output of the digital polarity determinator 130, routing the input sequence of pulses by the polarity switch 120 to the output 135 when the polarity of the input sequence of pulses is a predetermined polarity, and routing the input sequence of pulses to the output 135 via the inverter 125 when the polarity of the input sequence of pulses is not the predetermined polarity, thereby providing an output sequence of pulses having only the predetermined polarity.
