    • A method and apparatus are disclosed for providing audio-visual communication between registered users. Similar to the traditional walkie-talkie, a user depresses a button to transmit audio information, such as voice, and releases the same button to receive audio information from a transmitting device. Additionally, when communicating to another unit, the transmitting unit can also simultaneously send streaming video or still pictures in conjunction with audio communication. Both the audio and streaming video are transmitted and received in real-time. Still pictures may be stored or transmitted at any time. Each unit comprises a transmitter, antenna, camera, speaker, display screen and battery that are compact enough to be taken anywhere and allow for mobility. To enable security of the device, users must register with each other while within range before any communication can begin. This invention will allow users to communicate with each other for both business and recreational purposes.
    • 公开了一种用于在注册用户之间提供视听通信的方法和装置。 类似于传统的对讲机,用户按下按钮来发送诸如语音的音频信息,并且释放相同的按钮以从发送设备接收音频信息。 此外,当与另一单元通信时,发送单元还可以与音频通信一起同时发送流式视频或静态图片。 音频和流视频都是实时传输和接收的。 可以随时存储或传送静态图片。 每个单元包括发射器,天线,相机,扬声器,显示屏和电池,其紧凑性足以在任何地方进行移动。 为了实现设备的安全性,在任何通信开始之前,用户必须在范围内相互注册。 本发明将允许用户为了商业和娱乐目的彼此通信。

    • A structure and process for producing an even cut for window covering horizontal slat sets includes a cutting sleeve attached at opposite ends of the slats of a window covering horizontal slat set to be cut which gather in selective ones of the slates together for cutting in a way which minimizes collective bowing and ripping of the finished surface immediately adjacent the cut ends of the slats. The cutting sleeves can be spaced to hold groupings of 1, 2, 3, 4, 5, 6, 7, or more slats. Embodiments of the cutting sleeves can have two main opposite walls or eliminate one wall in favor of a comb topography which can load from the side.
