Most of the XY positioning stages proposed in previous studies are mainly designed by considering only a single performance indicator of the stage. As a result, the other performance indicators are relatively weak. In this study, a 2-degree-of-freedom linear compliant positioning stage (LCPS) is developed by mechatronic design to balance the interacting performance indicators and realize the desired positioning stage. The key parameters and the coupling of the structure and actuators are completely considered in the design. The LCPS consists of four voice coil motors (VCMs), which are conformally designed for compactness, and six spatial leaf spring parallelograms. These parallelograms are serially connected for a large travel range and a high out-of-plane payload capacity. The mechatronic model is established by matrix structural analysis for structural modeling and by Kirchhoff’s law for the VCMs. The sensitivities of the key parameters are analyzed, and the design parameters are subsequently determined. The analytical model of the stage is confirmed by experiments. The stage has a travel range of 4.4 mm× 7.0 mm and a 0.16% area ratio of workspace to the outer dimension of the stage. The values of these performance indicators are greater than those of any existing stage reported in the literature. The closed-loop bandwidth is 9.5 Hz in both working directions. The stage can track a circular trajectory with a radius of 1.5 mm, with 40 mm error and a resolution of lower than 3 mm. The results of payload tests indicate that the stage has at least 20 kg out-of-plane payload capacity.

群成员可撤销的群签名中,验证者本地撤销机制似乎是一种更为灵活的选择,因为在签名验证过程中,仅需验证者获取最新的撤销信息,而不涉及签名者。与经典的数论型构造相对应,Langlois等人给出了后量子安全的首个格上验证者本地撤销群签名。然而,截至目前,所有格上验证者本地撤销群签名方案暂不满足后向无关联性,该特性可保障群成员被撤销前其对消息签名的匿名性和无关联性。本文给出了首个格上后向无关联性安全的验证者本地撤销群签名方案,从而解决了这一公开问题。新方案为群公钥和群成员签名密钥节省了O(log N)的比特大小,并且没有任何公钥加密。特别地,新方案在随机谕言机模型下是可证明安全的,其困难性可归约至两个经典格上难题假设,即小整数解难题和差错学习难题。
