    摘要: Supplementing the movement stroke of a trackpad with a haptic response is one way to restore some or all of a reduced trackpad feel and overall performance caused by a reduction in the movement stroke. However, incorporating haptic responses in a clickable trackpad may interfere with accurate force measurement using physical movement of the trackpad as a proxy. The following describes haptic trackpads with anisotropic compliant spacers. The disclosed haptic trackpads permit selective haptic responses to a user, while also permitting accurate force measurement using displacement of a sensing surface caused by the user's finger(s) as a proxy.

    摘要: A key structure includes a base plate, a structural plate, a sound generation assembly and a keycap. The structural plate is installed on the base plate. The sound generation assembly includes a shaft body and a cantilever element. The cantilever element is protruded from a side of the shaft body. The structural plate is covered by the keycap. The keycap includes a first protrusion post and a second protrusion post. A first space and a second space are formed between the first protrusion post and the second protrusion post. The first space and the second space are not aligned with each other. The cantilever element is movable within the first space and the second space. Consequently, the feedback of a click sound is generated.

    摘要: An input device includes at least one key structure and a film circuit board disposed below the key structure. The key structure includes a top cover, a plunger, a sleeve, a rod, a first elastic element, a second elastic element and a bottom cover. The plunger is assembled on the top cover and has a protruding portion protruding from a first opening of the top cover and a guiding portion. The sleeve is assembled inside the plunger. The rod is movably disposed in the sleeve. The first elastic element is disposed in the rod, wherein the guiding portion passes through the first elastic element so that a first end of the first elastic element leans against the plunger. The bottom cover having a second opening locks the top cover. A second end and a third end of the second elastic element respectively lean against the sleeve and the bottom cover.

    摘要: A keyboard with at least some double action keys is described. The keyboard includes at least two layers disposed below the keys and the keys are selectively used to make contacts on one layer, or pass through and provide contacts with or on the second layer. All or at least some of the keys of the keyboard can be pushed partially down to generate a first command and can be pushed fully down for generating a second command.

    摘要: Systems and methods are disclosed that enable spring loaded mechanical key switch assemblies having variable displacement sensing capabilities. In one example, the disclosed key switch assemblies may be implemented in a keyboard system and used for providing variable displacement output signals that may be processed by a controller for input to a host processing device of an information handling system, such as a desktop or notebook computer. In another example, the disclosed key switch assemblies may be configured to provide both a digital “make” connection signal and separate variable displacement output signal/s that may be processed for input to a host processing device of an information handling system.

    摘要: A mechanical computer keyboard including a plurality of keys and an input/output (i/o) interface for output of registration of pressing one or more of the plurality of keys. Each key includes a keycap, a key switch including a stem, a key registration unit for registering a keystroke, and a spring for forcing the keycap in a neutral release position and providing a perceptible increase in pressing force. The keyboard further includes an analog-to-digital converter and the keys include a distance sensor unit for determining a travel distance of the pushing-down of the keycap by measuring a complex electrical impedance corresponding to the travel distance of the pushing-down the keycap, wherein the analog-to-digital converter is configured to convert the complex electrical impedance to a digital input signal including a digitalized keystroke travel distance for outputting of the digital input signal by the i/o interface towards the computer.
