    • A piezoelectric tactile input device and method in a computing environment. An embodiment disclosed herein includes a touch screen having a piezoelectric material layer that may generate a voltage when deformed in a localized area. The piezoelectric layer may also include a pattern of sensors for detecting the voltage generated. The detected voltage signals may then be used to extrapolate the position of the localized area in which the piezoelectric layer was deformed (e.g., from a finger touch or a stylus). Further, because the piezoelectric layer generates a greater voltage in the presence of a greater pressure, the device may further decipher a relative level of force for the tactile input on the touch screen.
    • 计算环境中的压电触觉输入装置和方法。 本文公开的实施例包括具有压电材料层的触摸屏,当压电材料层在局部区域中变形时可产生电压。 压电层还可以包括用于检测所产生的电压的传感器的图案。 然后可以使用检测到的电压信号来推断压电层变形的局部区域的位置(例如,从手指触摸或触针)。 此外,由于压电层在存在较大压力的情况下产生更大的电压,所以该装置可以进一步破译用于触摸屏上的触觉输入的相对水平的力。

    • A folding knife comprises a lock configured to more securely hold the blade in an extended position than conventional locks of conventional knives. The folding knife includes a handle, a blade movable relative to the handle to an extended position, and the lock that retains the blade in the extended position. The blade includes a cutting edge, and a tang that has a cavity and that is attached to the handle and pivotable about a pivot axis. The cavity includes a central axis parallel or substantially parallel with the pivot axis and that is located a distance away from the pivot axis that is greater than the distance between the pivot axis and the end of the handle. The lock includes a pin moveable relative to the handle and insertable into the cavity to retain the blade in an extended position. The lock holds the blade more securely by contacting the blade a further distance away from the location where the blade is attached to the handle than the distance between the same two locations of a conventional folding knife.
    • 折叠刀包括锁定构件,以将传统刀的传统锁定更为牢固地保持刀片处于延伸位置。 折叠刀包括手柄,可相对于手柄移动到延伸位置的刀片,以及将刀片保持在延伸位置的锁。 叶片包括切割边缘和柄部,其具有空腔并且连接到手柄并且绕枢转轴线枢转。 空腔包括平行于或基本上平行于枢转轴线的中心轴线,并且该中心轴线远离枢转轴线的距离大于枢转轴线和手柄的端部之间的距离。 锁包括可相对于手柄移动并可插入空腔中的销,以将刀片保持在延伸位置。 通过使刀片与常规折叠刀的相同两个位置之间的距离远离刀片附接到手柄的位置更远的距离使刀片更牢固地保持刀片。

    • A paint roller comprising: a frame; a roller cage assembly rotatably mounted to the frame; and a roller cover removably mountable to the roller cage assembly, the roller cover defining a roller cover passageway. The roller cage assembly includes a hub for mounting the roller cover thereonto, the hub defining a hub outermost surface insertable in the roller cover passageway and a locking mechanism for selectively locking the roller cover, the locking mechanism including a locking element movable between a locking position and a releasing position, the locking element defining a protruding portion. In the locking position, the protruding portion protrudes from the hub outermost surface. In the releasing position, the protruding portion is retracted inwardly relative to the hub outermost surface.
    • 一种漆辊,包括:框架; 可旋转地安装到框架的滚子保持架组件; 以及可拆卸地安装到滚子保持架组件的滚轮盖,滚轮盖限定了辊盖通道。 滚子保持架组件包括用于将辊盖安装到其上的轮毂,轮毂限定可插入辊盖通道中的轮毂最外表面和用于选择性地锁定辊盖的锁定机构,该锁定机构包括可在锁定位置 和释放位置,所述锁定元件限定突出部分。 在锁定位置,突出部分从轮毂最外表面突出。 在释放位置,突出部分相对于轮毂最外表面向内缩回。
