    • A correction device for typewriters and the like, including a material, preferably in liquid form, maintained at a predetermined pressure within a container. The container outlet is coupled through a narrow elongated tube whose dispensing end is positioned upon the typewriter carriage or other device so as to be located immediately across from the last printed character or other symbol. An operating switch activates an electronic circuit for dispensing a measured amount of the material over the last printed character, the color of said material being the same as the paper being printed upon to provide the same effect as erasure of the character. The dispensing of the measured dosage may be accomplished either by electronic or mechanical means. The erasure means may be provided as an integral part of the typewriter unit or as an independent stand-alone accessory.
    • 用于打字机等的校正装置,包括优选为液体形式的材料,其保持在容器内的预定压力下。 容器出口通过窄的细长管连接,其分配端位于打字机托架或其他装置上,以便立即与最后打印的字符或其他符号对准。 操作开关激活用于在最后打印字符上分配测量量的材料的电子电路,所述材料的颜色与正在打印的纸张相同,以提供与字符擦除相同的效果。 测量剂量的分配可以通过电子或机械手段来实现。 擦除装置可以作为打字机单元或独立的独立附件的组成部分提供。

    • A wireless hearing assist device including a microphone unit and a receiver unit. The microphone unit includes a microphone that receives audio signals, a frequency profile adjustment control circuit that adjusts frequency profile of the received audio signals based on input by a user, and a transmitter that wirelessly transmits the adjusted audio signals. The receiver unit is adapted to be worn by the user and includes a receiver that wirelessly receives the adjusted audio signals transmitted by the transmitter, and a speaker that generates sound based on the adjusted audio signals. In at least one embodiment, the microphone unit includes a Bluetooth enabled RF communication link for wireless communication with an external device other than the receiver unit.
