Abstract: An information handling system includes a printed circuit board, a screw, and a processor. The printed circuit board includes a through hole via. The through hole via includes top and bottom sections plated with a conductive plating material, and a middle section without any conductive plating material. The screw in physical communication with the top, middle, and bottom sections of the through hole via in the printed circuit board. The processor determines whether an electrical circuit is formed between the screw, the top section of the through hole via, and the bottom section of the through hole via. Based on the determination of the electrical circuit being formed, the processor provides an indication that no intrusion has been made into the information handling system.

Abstract: An ammonium fluoride gas may be used to form a protection layer for one or more interlayer dielectric layers, one or more insulating caps, and/or one or more source/drain regions of a semiconductor device during a pre-clean etch process. The protection layer can be formed through an oversupply of nitrogen trifluoride during the pre-clean etch process. The oversupply of nitrogen trifluoride causes an increased formation of ammonium fluoride, which coats the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) with a thick protection layer. The protection layer protects the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) during the pre-clean process from being etched by fluorine ions formed during the pre-clean process.

Abstract: A touch detection circuitry includes an analog-to-digital converter (ADC), a controller, and a packet generator. The ADC is arranged to convert touch signals of a touch panel from analog form into digital form. The controller is electrically connected to the ADC, and is configured to calculate at least one coordinate point and at least one touch size respectively corresponding to at least one touch event on the touch panel based on the touch signals. The packet generator is electrically connected to the controller, and is configured to encapsulate the at least one coordinate point and the at least one touch size into a touch data packet.

Abstract: An integrated circuit includes an upper threshold circuit configured to set a logic level of a first enabling signal, a lower threshold circuit configured to set a logic level of a second enabling signal, and a control circuit configured to change an output voltage signal in response to a condition that the logic level of the first enabling signal and the logic level of the second enabling signal are changed consecutively. In the control circuit, a first switch is electrically connected to a second switch at a buffer output node. The control circuit includes a regenerative circuit configured to maintain the output voltage signal at the buffer output node while each of the first switch and the second switch is at a disconnected state.

Abstract: An integrated circuit includes an upper threshold circuit, a lower threshold circuit, and a control circuit. The upper threshold circuit is configured to set a logic level of a first enabling signal based on comparing an input voltage signal with an upper threshold voltage. The lower threshold circuit is configured to set a logic level of a second enabling signal based on comparing the input voltage signal with a lower threshold voltage. The control circuit is configured to change an output voltage signal from a first voltage level to a second voltage level when the logic level of the first enabling signal and the logic level of the second enabling signal are changed consecutively.

Abstract: A buffering device includes: a buffering circuit coupled between a first voltage source providing a first voltage level and a second voltage source providing a second voltage level, for selectively outputting an output signal with the first voltage level or the second voltage level according to an input signal; and a controlling circuit coupled to the buffering circuit, for generating a first control signal to disconnect the buffering circuit from the first voltage source and generating a second control signal to connect the buffering circuit to the second voltage source when the buffering circuit transits the output signal from the first voltage level to the second voltage level. The second voltage level is different from the first voltage level.
