摘要： A system and method is provided for selecting a light source in a pointing device such as a mouse. The selection of the light source may be based on attributes of a received image, which are in turn based on reflected light received at the pointing device from the tracking surface. Because the attributes of the receive image are related to characteristics of the tracking surface over which the pointing device is moved, an illumination source appropriate for a particular surface type can be chosen.
摘要翻译：提供了一种用于在诸如鼠标的指示设备中选择光源的系统和方法。光源的选择可以基于接收到的图像的属性，其依次基于在跟踪表面处在指向设备处接收的反射光。由于接收图像的属性与指示装置所在的跟踪表面的特征相关，所以可以选择适合于特定表面类型的照明源。

摘要： Force measuring systems for electronic pens, styli, or other products may include structure for changing a direction or location of application of a force (e.g., a force transmitted via pen or stylus contact with a writing surface) from a first direction or location to a second direction or location. In this manner, a sensor portion of the force measuring system may be reoriented in a direction such that it is not normal to the direction of the force. This feature may help make electronic pens or styli (or other products) thinner and dimensioned more consistent with their non-electronic counterparts. Various structures for changing the direction or location of application of the force are described.
摘要翻译：用于电子笔，测针或其他产品的力测量系统可以包括用于改变施加方向或位置的结构（例如，通过笔或触笔与书写面接触的力）从第一方向或位置到第二个方向或位置。以这种方式，力测量系统的传感器部分可以在使得其不受力的方向不正常的方向上重新定向。此功能有助于使电子笔或触笔（或其他产品）更薄和尺寸更符合其非电子对手。描述用于改变施加力的方向或位置的各种结构。

摘要： An apparatus, with moving parts, having a flexible circuit configured such that its fatigue life is enhanced. The apparatus includes a first component, a second component, and a positioning mechanism between the first component and the second component. The positioning mechanism enables movement of the first component and the second component between at least a proximate position and a spaced-apart position. Also included between the first component and the second component is a flexible circuit that has a first end coupled to the first component and a second end coupled to the second component. The flexible circuit is configured as a compliant spring that can extend and collapse in a predefined shape when the components are spaced-apart and proximate, respectively.

摘要： A flexible chip carrier with contact pads on its upper surface matching those of the chip with said pads conductively connected to land grid array (LGA) pads on its lower surface matching the those of a card or PCB. The chip carrier is provided with a stiffening layer at the LGA interface. The stiffening layer is mechanically attached to the lower surface of the chip carrier. Holes are formed in the stiffening layer to expose the LGA pads. The holes are then filled with a conductive adhesive material.
