摘要： 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.

摘要： 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.

摘要： 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.

摘要： A touch panel device includes a face plate, a force-feedback device, and a touch panel circuit. The face plate receives at a first surface a contact with the face plate. The force-feedback device includes a PCB affixed by a first surface of the PCB to a second surface of the face plate. The PCB includes a first metallic ring on a second surface of the PCB. The piezo disc includes a piezoelectric wafer and a second metallic ring. The piezo disc is adjacent to the second surface of the PCB. The touch panel circuit is coupled to the first metallic ring, the second metallic ring, and the piezoelectric wafer. The touch panel circuit determines a capacitance between the first metallic ring and the second metallic ring, determines a force associated with the contact based upon the capacitance, and triggers a haptic feedback response in the piezoelectric wafer.
