摘要:
Methods and apparatus are described for enabling a user using a communication device, such as a cell phone, to make and receive calls in a hands-free mode and utilize an existing audio system, such as a radio, to output audio received from the other party, i.e., the calling or called party. An accessory containing an RF transmitter and a microphone, among other components, is attached mechanically to a communication device, for example, using a clip. There is no electrical or digital connection between the accessory and the communication device. The accessory has an internal microphone which is positioned close to the speaker of the communication device to detect sounds waves emanating from the speaker. The sound waves are converted to an RF signal and transmitted to a radio at a particular radio frequency channel thereby allowing the user to hear the other party's voice over the radio speakers. The communication device is placed near the user so that the microphone of the cell phone can sufficiently detect the user's voice. The communication device need not be held by the user thereby keeping both hands of the user free.

A drawing tool for creating stripped patterns or multi-colored lines, such as rainbows. The drawing tool includes a set of removable cartridges of varying sizes, nib shapes and colors, each of which is interchangeable with others of its own size or with a set ratio of lager or smaller cartridges.

摘要:
A water color painting kit is disclosed having a central body (12), a palette (14) detachably engagable with the central body and a variety of brushes. The central body defines a plurality of water supply chambers (22) therein. The palette (14) includes a color supply portion that carries a variety of color blocks (30). The color blocks (30) are secured to a base member (50) that snap fits into openings in the palette (14). The base member (50) has a extension to facilitate the removal and insertion of the base member. In a working configuration, guides located on the palette (14) engage slits on the central body to connect the palette with the central body (12). In a storage configuration, the palette is disengaged from the central body and stored on the water supply chamber (22). In a multiple-user embodiment, the kit includes a plurality of palettes engaged with the central body.
