20110203912 | STACKED METAL AND ELASTOMERIC DOME FOR KEY SWITCH - A low travel keyboard and methods of fabrication are described. The low-travel keyboard is suitable for a thin-profile computing device, such as a laptop computer, netbook computer, desktop computer, etc. The keyboard includes a key cap positioned over stacked elastomeric and metal domes. The quick force drop of the metal dome provides the crisp “snappy” feel for the user and the elastomeric dome provides the ability for longer travel than the metal dome alone. The metal dome also activates the switch circuitry of the membrane on printed circuit board. The stacking of the elastomeric metal domes takes advantage of the abrupt force drop in the metal dome buckling and applies it to the elastomeric dome force, making it possible to design a low-travel key while still maintaining or improving the tactile feeling of the key switch. | 08-25-2011 |
20110303521 | NARROW KEY SWITCH - A narrow key switch for a low travel keyboard and methods of fabrication are described. The low-travel keyboard having narrow keys is suitable for a thin-profile computing device, such as a laptop computer, netbook computer, desktop computer, etc. The keyboard includes a key cap positioned over an elastomeric dome and a two-part scissor mechanism having two separate linkage structures on opposite sides of the dome. A link bar is also provided to transfer a load from a side of a key to the center if the key cap is depressed in an off-center manner. Transferring the load to the center helps to deform the elastomeric dome so that it can activate the switch circuitry of the membrane on printed circuit board underneath the dome. Separating the linkage structures into two separate parts allows for the use of a full-sized elastomeric dome for a narrow key switch. The full-sized dome provides the desired tactile feedback to a user. Thus, the tactile feel of the key is not compromised even thought the key is narrower than a conventional key. | 12-15-2011 |
20120043191 | SINGLE SUPPORT LEVER KEYBOARD MECHANISM - A keyboard mechanism for a low-travel keyboard and methods of fabrication are described. The low-travel keyboard is suitable for a thin-profile computing device, such as a laptop computer, netbook computer, desktop computer, etc. The keyboard includes a key cap that can be formed of a variety of materials in the form of a flat slab. The key cap is attached to one end of a support lever that supports it from underneath. In one embodiment, the support lever is formed of a rigid material and is pivotally coupled with a substrate on the other end. In another embodiment, the support lever is formed of a flexible material and is fixedly attached to the substrate on the other end. The portion of the support lever that is attached to the key cap is positioned over a metal dome that can be deformed to activate the switch circuitry of the membrane on printed circuit board underneath the dome. | 02-23-2012 |
20120199455 | KEYBOARD DESIGN - Embodiments of a backlit keyboard assembly are described. A keycap assembly is mounted into a case web having intersecting ribs. A flange, which can be angled, is on the bottom perimeter of the keycap and a correspondingly shaped flange is on each rib of the case web. An overlap of the keycap flange and the case web flanges prevents direct sighting of the backlight light source and also provides a more evenly distributed halo around the keycap, thereby improving both aesthetics and functionality by providing better light control and contrast. | 08-09-2012 |
20130161171 | Keyboard Mechanisms for Electronic Devices - An input device configured to communicate with a computing device includes at least one keycap, a support mechanism operably connected to the keycap and configured to move the keycap from a first position to a second position, and a feature plate operably connected to the support mechanism. The support mechanism includes a first support and a second support. The first support and the second support are each connected to the at least one keycap and the feature plate. The first support and second support pivot to allow vertical movement of the keycap but lateral movement of the first support and second support are restricted. | 06-27-2013 |
20130161172 | Keyboard with Position Sensing Mechanism - An input device configured to communicate with a computing device includes at least one keycap, a support mechanism operably connected to the keycap and configured to move the keycap from a first position to a second position, a feature plate operably connected to the support mechanism, and a sensing member. The sensing member is configured to detect at least one of a change of position of the at least one keycap, a speed of the at least one keycap, an amount of force applied to the at least one keycap, or a location of a finger. The sensing member may be a capacitive sensor. In some embodiments, the input device may not include the support mechanism and the sensing member may be configured to detect the location of a finger regardless whether or not the keycap moves. | 06-27-2013 |
20130162450 | Illuminated Keyboard - In a first embodiment, an input device includes at least one keycap, a support mechanism configured to move the keycap from a first position to a second position, a feature plate having at least one anchoring mechanism operably connected to the support mechanism, and an illumination panel. The illumination panel is positioned between the at least one keycap and the feature plate. The at least one anchoring member extends through a portion of the illumination panel. In a second embodiment, an input device includes a keycap, a support mechanism configured to move the keycap, a support plate operably connected to the support mechanism, and an illumination panel. The illumination panel includes a light source, a light guide, and a frame substantially surrounding the light guide. Light illuminated from the light source is directed by the light guide and the frame towards the keycap. | 06-27-2013 |
20130164068 | BONDED KEYBOARD AND METHOD FOR MAKING THE SAME - A bonded keyboard and method for making the same are disclosed. The bonded keyboard uses adhesive as the primary agent, and in some embodiments, as the sole agent for coupling various components of the keyboard stackup together. The keyboard stackup uses a skeletal adhesive to couple a top case to a backcase assembly. In one embodiment, the skeletal adhesive is an interconnected matrix of ribs dimensioned to fit within the spacing existing between adjacent keys, which are mounted on the backcase assembly. The skeletal adhesive is fixed to the backcase assembly, occupies a portion of the spacing that exists between keys, and the top case is fixed to the top of the skeletal adhesive. | 06-27-2013 |
