Security hardened function keys and indicators

A key-press detection circuit for an information handling system includes a detector circuit, a RC circuit, and a latch circuit. The detector circuit is coupled to a keyboard matrix device, and operates to provides a clock signal in a first state when a particular key of the keyboard matrix device is pressed and to provide the clock signal in a second state when the particular key is not pressed. The RC circuit receives the clock signal and provides a timed clock signal in a third state for a predetermined amount of time in response to receiving the clock signal in the first state. After the predetermined amount of time, the RC circuit provides the timed clock signal in a fourth state. The latch circuit receives the timed clock signal at a clock input, receives a data signal at a data input, and latches an output signal in a same state as the data signal when the timed clock signal changes from the third state to the fourth state.

A backlight keyboard includes a first language keyswitch set having adjacent first and second keyswitches, a first backlight module disposed under the first language keyswitch set, and a masking sheet. The masking sheet is suitable for the backlight keyboard and a second backlight keyboard including a second backlight module and a second language keyswitch set. The first and second keyswitches on the backlight keyboard coincide with a third keyswitch in the second language keyswitch set on the second backlight keyboard. The masking sheet has a first light-exit region layout corresponding to the first, second, and third keyswitches for allowing light to be incident to symbols on the first, second, and third keyswitches. In other words, the masking sheet of the present invention can be applied to different backlight keyboards having different language keyswitch sets.

Concealable input region for an electronic device

Embodiments are directed to an electronic device having a hidden or concealable input region. In one aspect, an embodiment includes an enclosure having a wall that defines an input region having an array of microperforations. A light source may be positioned within a volume defined by the enclosure and configured to propagate light through the array of microperforations. A sensing element may be coupled with the wall and configured to detect input received within the input region. The array of microperforations are configured to be visually imperceptible when not illuminated by the light source. When illuminated by the light source, the array of microperforations may display a symbol.

A controlling device has a configurable key. An insert is provided to the configurable key and includes an indicium representative of a media content provider. An image of the indicium or an image of a QR code associated with the indicium is used to assign one or more commands to the configurable key. The one or more commands are used to cause a controllable device to tune to a channel on which the media content provider is being broadcast, to invoke an app associated with the media content provider, to access a website associated with the media content provider, and the like.

CONTROL DEVICE WITH CAPACITIVE-TYPE VISUAL KEY STRUCTURE
20230268922 · 2023-08-24 ·

A control device with a capacitive-type visual key structure is provided. The control device includes a covering member and a transparent keycap. The covering member includes an accommodation space. The transparent keycap is accommodated within the accommodation space. An elastic element, a first electrode, a key circuit board assembly with a second electrode and a display panel are accommodated within the accommodation space. When the transparent keycap is pressed down, the elastic element is correspondingly moved, and a spatial distance between the first electrode and the second electrode is changed. Consequently, a capacitance change value is formed. According to the capacitance change value, the control device judges whether the transparent keycap is pressed down and triggered.

Flexible touch sensing system and method

A single volume soft sensor capable of sensing real-time continuous contact and stretching. A low-cost and an easy method to fabricate such piezoresistive elastomer-based soft sensors for instant interactions is also provided. An electrical impedance tomography (EIT) technique is employed to estimate changes of resistance distribution on the sensor caused by fingertip contact. To compensate for the rebound elasticity of the elastomer and achieve real-time contact sensing, an adaptive baseline update for EIT is utilized. The baseline updates are triggered by fingertip contact and movement detections.
