Abstract: An information handling system includes a touchpad that accepts touch inputs to move a cursor on a display and that deflects at a front side to accept button inputs. A bracket is disposed between a touch detection surface and circuit board of the touchpad to bias the touch detection surface up and deflect in response to a push down as a button input. Conical spring ground devices coupled to the circuit board on opposing sides of the bracket interface with an ohmmeter included on the circuit board that detects a resistance from a first ground device through the system ground to a second ground device. Resistance across ground is applied by the touchpad processor to adjust touch detection sensitivity and avoid ghost inputs.

Abstract: Systems and methods for a hack-proof security keyboard are described. In some embodiments, a keyboard module may include a first circuit configured to detect activation of a plurality of keys and a second circuit configured to detect activation of a subset of the plurality of keys, where the second circuit overlies the first circuit. In other embodiments, a method may include detecting an electrical signal received from a secondary membrane of a keyboard, where the keyboard includes a primary membrane configured to detect individual activation of any of a plurality of keys, and where the secondary membrane is configured to output the electrical signal in response to concurrent activation of a subset of the plurality of keys. The method may also include performing a selected action in response to the detection.

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 is 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 information handling system includes keyboard backlights, an embedded controller, and a processor. The embedded controller communicates with the keyboard backlights. In response to an activate keyboard backlights signal, the embedded controller turns on the keyboard backlights. In response to a deactivate keyboard backlights signal, the embedded controller turns off the keyboard backlights. The processor communicates with the embedded controller. The processor determines whether an ultrasonic waveform is received. In response to the ultrasonic waveform being received, the processors provide the deactivate keyboard backlights signal to the embedded controller. In response to the ultrasonic waveform not being received, the processor provides the activate keyboard backlights signal to the embedded controller.

Abstract: A touch panel device includes a face plate, a bracket, and a PCB. The face plate receives a contact. The bracket includes a permanent magnet affixed to a surface of the bracket. The PCB is positioned proximate to the bracket such that a surface of the PCB is adjacent to the bracket. The PCB includes a Hall sensor collocated proximate to the permanent magnet. The touch panel circuit is coupled to the Hall sensor. When the contact is received at the face plate, the PCB moves closer to the bracket. In response, the touch panel circuit receives a voltage from the Hall sensor, determines a force associated with the contact based upon the voltage, and triggers a haptic feedback response in the bracket.
