    • An over-the-ear Bluetooth® type communications headset for hands-free communication with mobile phones and similar devices, the headset being convertible to a ring configuration for wearing on the finger as a communications device and as jewelry. The headset is divided into ear-piece and voice-piece halves that swivel between headset and ring modes, with respective S- and circular shapes, and includes function-changing contacts that respond to the realignment of the halves in the respective headset and ring modes to optimize the device's use for over-the-ear or finger wear. A further feature is a set of interior spring contacts projecting from the inner circumference of one of the halves, the contacts having both electrical recharging and finger-fitting functions, and a finger-shaped charging base for recharging the headset in the ring configuration via the spring contacts.

    • A multi-element read-write magnetic recording head for recording information on a magnetic tape and for reading recorded information therefrom is provided. The recording head comprises an equal number of associated read elements and write elements to form a two-gap recording head comprising pairs of read and write elements. The two-gap recording head further comprises a first module and a second module, the first and second modules each comprising a plurality of read and write head elements. A first group of read and write heads is configured to perform in a forward direction of movement of the magnetic tape and a second group of read and write heads is configured to perform in a reverse direction of movement of the magnetic tape. One of the modules contains an equal number of forward read heads and reverse write heads and the other of the modules contains an equal number of reverse read heads and forward write heads, to provide decoupling of reading and writing functions and to enable servoing by a given read element of a write element associated therewith. Asymmetry of the magnetic recording head is provided by offsetting leads to the read elements in a given module from leads to said write elements in the same module, while maintaining orthogonality between read and write element leads near the read and write elements. The asymmetry minimizes both inductive and capacitive feedthrough into adjacent readers. As a consequence, noise produced during the writing process is reduced, providing an improved signal-to-noise ratio and thereby permitting same gap servoing.
    • 提供了一种用于在磁带上记录信息并从其读取记录信息的多元素读写磁记录头。 记录头包括相等数量的相关联的读取元件和写入元件,以形成包括读取和写入元件对的双隙记录头。 双隙记录头还包括第一模块和第二模块,第一和第二模块各自包括多个读写头元件。 第一组读写头被配置为在磁带的向前移动方向上执行,并且第二组读写头被配置为在磁带的相反移动方向上执行。 其中一个模块包含相同数量的正向读取头和反向写入头,另一个模块包含相等数目的反向读取头和正向写入头,以提供读取和写入功能的去耦合,并使得能够通过给定的 读取与之相关联的写元件的元素。 通过将给定模块中的读取元件的引线偏移到同一模块中的引线到所述写入元件,同时保持读取和写入元件附近的读取和写入元件引线之间的正交性,来提供磁记录头的不对称性。 不对称性使电感和电​​容馈通最小化到相邻的读取器中。 因此,在写入处理期间产生的噪声减小,提供了改善的信噪比,从而允许相同的间隙伺服。
