    • There is provided an interactive device capable of providing input data to a computer program in response to user interactions, the interface device comprising a first position sensor reading a sensed location of the interface device having a free roaming movement in a three-dimensional space, a direction vector determination device determining a direction vector indicating an aiming direction, and a transmission system communicating aim information to an external device implementing the computer program. The transmission system may include a transmitter for the direction vector and/or a transmitter for the sensed location. The computer program can use the aim information and input data to support a projected 3D game environment or other application providing sensory feedback in response to the user interactions. Multiple interactive devices having unique identifiers may also be supported. The interactive device enables significant freedom to roam relative to implementing equipment, as compared to existing interactive devices having only a limited range of movement relative to implementing equipment.
    • 提供了一种能够响应于用户交互向计算机程序提供输入数据的交互式设备,该界面设备包括第一位置传感器,其读取在三维空间中具有自由漫游运动的接口设备的感测位置, 确定指示瞄准方向的方向矢量的方向矢量确定装置,以及将目标信息传送到实现该计算机程序的外部装置的传输系统。 传输系统可以包括用于方向矢量的发射机和/或用于感测位置的发射机。 计算机程序可以使用目标信息和输入数据来支持预测的3D游戏环境或响应于用户交互而提供感觉反馈的其他应用。 还可以支持具有唯一标识符的多个交互设备。 与相对于实施设备仅具有有限的移动范围的现有交互式设备相比,交互式设备实现相对于实施设备漫游的显着自由度。

    • Applicant has disclosed a foam swab for cleaning and lubricating firearms. In the preferred embodiment, the invention comprises: a molded plastic shank having a threaded free end and a series of parallel rings spaced between parallel spacers; and a foam cover, preferably made of polyurethane, thermally bonded to the spacers. To clean a firearm, solvent or lubricant is applied to the foam cover. Then the threaded end can be screwed into a gun cleaning rod and the foam swab drawn through a firearm bore.
    • 申请人已经公开了用于清洁和润滑火器的泡沫棉签。 在优选实施例中,本发明包括:模制塑料柄,其具有螺纹自由端和在平行间隔件间隔开的一系列平行环; 以及优选由聚氨酯制成的泡沫盖,其热粘合到间隔件上。 要清洁火器,溶剂或润滑剂应用于泡沫罩。 然后将螺纹端拧入喷枪清洁杆,并将泡沫棉签穿过枪支孔。
