摘要： Methods and systems for efficiently embedding information in a keyboard membrane. Information can be embedded in the keyboard membrane by integrating an information embedding circuit with a switch matrix used to identify location of a key press event. The information is embedded by either hardwiring a column to a selected row, or a row to a selected column. In order to access the embedded information, the row (column) is asserted resulting in the hardwired column (row) to also be asserted. The identification of the asserted column (row) is used to point to the embedded information.

摘要： 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.
摘要翻译：描述了用于低行程键盘的窄键开关和制造方法。具有窄键的低旅行键盘适用于诸如膝上型计算机，上网本计算机，台式计算机等的薄型计算设备。键盘包括位于弹性圆顶上的键帽和两部分剪刀机构在圆顶的相对侧上具有两个独立的连接结构。如果钥匙盖以偏心方式被按压，还提供连杆以将负载从钥匙的一侧传送到中心。将负载转移到中心有助于使弹性体圆顶变形，从而可以激活圆顶下方印刷电路板上膜的开关电路。将连接结构分成两个分开的部件允许使用用于窄键开关的全尺寸弹性体圆顶。全尺寸圆顶可为用户提供所需的触觉反馈。因此，即使认为钥匙比传统钥匙更窄，钥匙的触感也不会受到影响。

摘要： 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.
摘要翻译：描述背光键盘组件的实施例。键帽组件安装到具有相交肋的壳体腹板中。可以成角度的凸缘位于键帽的底部周边上，并且相应形状的凸缘位于壳体腹板的每个肋上。键帽凸缘和外壳腹板凸缘的重叠防止背光源的直接瞄准，并且还提供围绕键帽的更均匀分布的光晕，从而通过提供更好的光控制和对比度来改善美观和功能。

摘要： A computer keyboard includes a plurality of keys arranged in a pattern contained within a plane, a webbed structure defining openings for each of the keys, an illumination source, and one or more light pipes positioned along the webbed structure and arranged to deliver light from the illumination source to the keys, wherein each of the keys is illuminated thereby. Although the keys have the appearance of being backlit similar to traditional illuminated keyboards, the illumination source is actually located along at least one side of and within the same plane as the pattern of keys, rather than beneath the keys. The keyboard can thus be made thinner in such arrangements where the illumination source does not need to be located beneath the keys.
摘要翻译：计算机键盘包括以包含在平面内的图案布置的多个键，限定用于每个键的开口的网状结构，照明源，以及沿着网状结构定位的一个或多个光管，并布置成将来自照明源到键，其中每个键被照亮。虽然键具有类似于传统照明键盘的背光的外观，但是照明源实际上沿着键的图案而不是在键的下方沿着与键的图案相同的平面内的至少一侧并且位于同一平面内。因此，可以在这样的布置中使键盘更薄，其中照明源不需要位于键下方。
