    • An anti-theft alarm is provided, for a portable device such as a laptop computer. An embodiment of the anti-theft alarm comprises three main components: a uniquely coded tag for attachment to the bottom of the device, a pad upon which the device is placed, for sensing the tag, and an electrically powered control module. The module is connected to the pad. The control module is able to determine if the tag is still in contact with the pad--if not an alarm sounds immediately. The module can also determine if the electrical power has been disconnected and if the module has been moved (using a motion sensor). If there is no power and the module has been moved, an alarm sounds immediately. The alarm can be disabled with a key switch.
    • 为便携式设备(例如膝上型计算机)提供防盗报警器。 防盗报警器的一个实施例包括三个主要部件:用于附接到设备底部的唯一编码标签,放置该设备的垫,用于感测标签,以及电动控制模块。 模块连接到焊盘。 控制模块能够确定标签是否仍然与焊盘接触 - 如果不是立即发出警报声。 模块还可以确定电力是否已断开,并且模块是否已被移动(使用运动传感器)。 如果没有电源并且模块已被移动,则立即发出警报。 可通过钥匙开关禁用报警。

    • A flexible, retractable assembly for use as a door, space divider, covering or the like which comprises a sheet such as Mylar polyester film having a permanent memory set to roll up on itself or otherwise retract automatically into a coil, accordion, or other compact configuration. The assembly is adapted to be stored on one side of an opening and then guided across the opening to fully or partially cover the opening. The permanent memory set of the sheet permits it to retract at least partially under its own force to eliminate or minimize the need for separate rewinding apparatus. The sheet may substitute for a variety of standard products including entryway doors, closet, cabinet and shower doors, screen doors and windows, room dividers, machinery guards and covers for various items such as florescent light fixtures. The sheet may be combined with decorative finishes including a tambour composite structure providing aesthetic and functional advantages.
    • 用作门,空间分隔器,覆盖物等的柔性的可收回组件,其包括具有永久性存储器的片材,例如聚酯薄膜,其具有永久性存储器,其自身卷起或以其他方式自动缩回成线圈,手风琴或其它紧凑件 组态。 组件适于存储在开口的一侧,然后被引导穿过开口以完全或部分地覆盖开口。 片材的永久记忆组允许其至少部分地在其自身的力下缩回以消除或最小化对单独的倒带装置的需要。 纸张可以代替各种标准产品,包括入口门,衣柜,橱柜和淋浴门,屏风门窗,房间分隔线,机械防护罩和各种物品如荧光灯具的盖子。 该片材可以与装饰性饰面组合,包括提供美观和功能优点的t our复合结构。

    • A retractable conduit formed from a sheet of memory-set polyester. To manufacture the memory-set strip, the polyester sheet is wound into a desired coiled position. It is then heated and cooled in a manner to memory-set the sheet in a coiled form. After this process the sheet of polyester will automatically return to the coiled position after it has been uncoiled. In one form, suitable as a splashblock, the distal end of the polyester sheet is wider than the end attachable to a downspout. In another form the polyester sheet is sheathed in an elongated polyethylene tube, to form a retractable hose. In a preferred form, the distal end of the hose is supported on a spool which will roll along the ground as the hose is wound and unwound to further ensure that the hose retracts properly. The tube can also be provided with holes to act as a sprinkler if desired.
    • 由一组记忆组聚酯形成的伸缩导管。 为了制造记忆纸条,将聚酯片材卷绕成所需的盘绕位置。 然后将其加热和冷却以将片材记录为盘绕形式。 在这个过程之后,聚酯薄片在被卷起后将自动回到卷绕位置。 在一种形式中,适合作为防溅块,聚酯片的远端比可附着到下水口的端部更宽。 在另一种形式中,聚酯片被套在细长的聚乙烯管中,以形成可缩回的软管。 在优选的形式中,软管的远端被支撑在卷轴上,该卷轴将沿着软管卷绕和展开以沿着地面滚动以进一步确保软管适当地缩回。 如果需要,管也可以设置有用作喷洒器的孔。
