Abstract: An external adapter circuitry is plugged into the printer port of a host computer to provide the utility of computer telephony for the host computer. The circuitry is housed in a compact box which is about the size of a common parallel port connector. The circuitry consists of a telephone line interface for receiving and sending signals from/to the telephone line; a printer port interface for sending data to and receiving data from the host computer; a couple of registers for latching signal-in and signal-out; a A/D converter for converting analog signals to digital signals; and a D/A converter for converting digitized signals to analog signals. More specially, the electricity of the entire circuitry is supplied from a signal-to-power converter which obtains voltages from the printer port. Therefore, the external adapter circuitry does not need a power line for external power supply.

Abstract: An aperture selection mechanism for camera lens includes an aperture strip and a disk selection knob. The aperture strip has two or more different sizes of apertures equally spaced from each other and being sequenced by size. Turning the selection knob, the aperture strip will be moved and one of the apertures will be positioned in the light path of the camera lens. Two or more apertures may be moved to the light path of camera lens one at a time so that the camera can produce better quality of photo and image. The structure is simple, low cost and easy to use.

Abstract: A sheet-fed scanner with selectively variable document feed-in and feed-out positions is provided. The sheet-fed scanner includes conventional scanning means for performing a scanning process on a document; conventional diving means for driving the document through the scanning process, a base plate; a main body for accommodating the scanning means and the driving means therein, the main body, being mounted on the base plate and having at least a base side, a first inclined side, and a second inclined side; and a passage formed between the base plate and the main body for guiding the document through the scanning process. By resting the sheet-fed scanner on various sides of the main body, the user can feed the document from various positions: when resting on the base plate, the passage is horizontally oriented, allowing a horizontal feed-in and feed-out of the document; when resting on the first inclined side, the passage is inclined in such a manner that allows an inclined top feed-in and bottom feed-out of the document; and when resting on the second inclined side of the main body, the passage is inclined in such a manner that allows an inclined bottom feed-in and top feed-out of the document. Moreover, the main body can be shaped in either a pentagonal or trapezoidal cross section so as to elevate either the feed-in and feed-out positions for either inclined or horizontal feed-in and feed-out.
