Abstract: A data input device for use with an optically rough tracking surface comprising a substantially coherent light source for projecting a substantially coherent light beam onto the tracking surface for scattering the substantially coherent light beam. An optic guides the projected substantially coherent light beam toward the tracking surface and comprises a first boundary facing the substantially coherent light source and a second boundary opposite the first boundary. A detector detects at least a portion of the scattered light beam comprising a speckle pattern. The optic is arranged such that the tracking surface is spaced from the second boundary by a distance sufficient to inhibit any substantial retro-reflection of the substantially coherent light beam striking the second boundary from striking the detector. A controller responsive to the detector operates the device in a tracking mode for utilizing the detected speckle pattern to track relative movement between the device and the tracking surface. The device is particularly useful in handheld and laptop devices, such as personal digital assistants, cellular phones, laptop computers, etc., where it is desirable to interact with a tracking surface comprising human skin, such as a fingertip.

Abstract: A new data communication system is described which enables data transmission over existing telephone lines at rates higher than possible with existing methods, including conventional modems. By using a novel asymmetric configuration of the two communication endpoints, the currently-accepted maximum theoretical limits on the data rate are no longer applicable. One endpoint is connected directly to a digital telephone network, whereas the other endpoint uses a conventional telephone connection. This reduces the transmission problem to compensation for a single telephone line interface and a single analog local loop. Means of providing this compensation and the required clock synchronization were also created, enabling a practical implementation of the system. The new system can achieve rates up to 64,000 bits-per-second and has broad utility in several active areas including wide-band audio transmission, video transmission, networking, facsimile transmission, and remote computer access.
