摘要： Rewritable signs (100, 1300) that include bistable cholesteric liquid crystal layers (102, 1402, 1404, 1406) are provided. According to one embodiment a rewritable sign (100) is devoid of circuitry for establishing electric fields in localize regions for writing information to the rewritable sign (100), and is consequently inexpensive. In the latter embodiment, a separate information writer (400) that includes an array of pixel electrodes (404) that is driven by an active matrix (602) is used to write information on the rewritable sign. According to another embodiment a rewritable sign (1300) includes three cholesteric liquid layers (1402, 1404, 1406) each of which reflects a different primary color. The three cholesteric liquid crystal layers (1402, 1404, 1406) are interleaved with sets of conductive lines (1316, 1320, 1322, 1324) that are used to apply signals to the cholesteric liquid crystal layers (1402, 1404, 1406) for the purpose of writing information.
摘要翻译：提供了包括双稳态胆甾型液晶层（102,1402,1404,1406）的可重写符号（100,1300）。根据一个实施例，可重写符号（100）没有用于在用于将信息写入可重写符号（100）的本地化区域中建立电场的电路，因此便宜。在后一实施例中，包括由有源矩阵（602）驱动的像素电极阵列（404）的单独信息写入器（400）用于写入关于可重写符号的信息。根据另一个实施例，可重写标志（1300）包括三个胆固醇液体层（1402,1404,1406），每个胆固醇液体层反映不同的原色。三个胆甾型液晶层（1402,1404,1406）与用于将信号施加到胆甾醇型液晶层（1402,1404,1406）的导线组（1316,1320,1322,1324）交错，用于写信息的目的。

摘要： An ultrasonically welded joint is made by placing a thermoplastic film (5) between two thermoplastic members (10, 20). The two thermoplastic members each have a mating part of a complex joint. One part of the joint, known as the shear joint (40), serves to shear away part (6) of the film when the two members come together, and another section of the same joint, known as the mash joint (30), serves to bond the film and the two members all together during the ultrasonic welding process.

摘要： A planar fuel cell (20) is provided, including a membrane electrode assembly (23) sandwiched between two current collector assemblies (21, 22). The membrane electrode assembly is a single sheet of a polymer electrolyte membrane with an array of anodes (27) on one side and an array of corresponding cathodes (28) on the other side. The current collectors (25) can be supported by a plastic frame (24), and they have an interconnect tab (26) that provides an electrical pathway to the exterior of the membrane electrode assembly. The interconnect tab is situated to provide electron transfer between the anodes and the cathodes such that the interconnect tab does not traverse the thickness of the polymer electrolyte membrane. When the planar fuel cell is assembled, the interconnect tab is sealed to prevent leaking of fuel or oxidant gases. Fuel is distributed (36) to only one side of the membrane electrode assembly and oxidant is distributed (36) only to the other side.
