Points of sale or service. According to various embodiment, a point of sale or service includes a register, a peripheral and a protocol converter. The protocol converter communicatively couples the register and the peripheral. The register may communicate with the protocol converter using a first protocol while the peripheral communicates with protocol converter using a second protocol. The register and the protocol converter may communicate using TCP/IP. A second peripheral may communicate with the register using the first protocol and without the aid of the protocol converter. The point of sale or service may further include a processor communicatively coupled to the protocol converter, for accessing the first peripheral.

A light-generated input interface is provided using a combination of components that include a projector and a sensor. The projector displays an image corresponding to an input device. The sensor can be used to detect selection of input based on contact by a user-controlled object with displayed regions of the projected input device. An intersection of a projection area and an active sensor area on a surface where the input device is to be displayed is used to set a dimension of an image of the input device.

In a sensory input system that detects movement of a user's fingers on an inert work surface, two or more input modes (for instance, keyboard and mouse) are provided within an overlapping or coextensive physical space. Depending on the currently active mode, the invention interprets the finger motions as input according to one of the input modes. Automated and/or manual mode-switching are provided.

A system is disclosed for measuring click traffic quality by scoring clicks made on sponsored advertisements. A click score generated by the disclosed system may enable advertisers and publishers to distinguish between legitimate and fraudulent clicks. The disclosed system may filter click data associated with a click made on a sponsored advertisement. The system may generate a click score that may represent the confidence with which the quality of a click may be determined. The system also may generate a confidence interval associated with the click score.

A signature capture device includes a CPU that executes a routine to losslessly compress signature data in realtime such that decompression recovers a legally acceptable replica of the original signature. Digital data representing the pixel start point of a signature run is stored in preferably 10-bit or 9-bit format, and is then reduced to a common lower format of 9-bit or 8-bits. Subsequent data points within a run are reduced to the same common lower format and are compared to the common lower format version of the start point data. The differential between the start point and the adjacent second point is calculated and encoded with 4-bits if possible, or with 8-bits otherwise. The differential between the third point and second point is calculated and encoded with 4-bits or 8-bits, as required, and so on, within the run. A run is initiated by a pen-down status, or if a present run exceeds a predetermined length, or if a differential can no longer be encoded with 4-bits and requires 8-bit encoding. For each run, the start position and differential pixel positions are encoded with a preferably 32-bit start block the provides pen-up and pen-down status (1-bit), run length (10 bit), encoding 4-bit or 8-bit status (1-bit) and up to 10 bits each for initial x and y pixel position.
