Abstract
A remote data capture system includes a host computing device. A client computing device is communicatively coupled to the host computing device. A capture device having a sensor is coupled to the client computing device. The capture device is configured to receive an electrical input signal from the sensor, convert the input signal to corresponding input data having a predetermined format, compress the input data to a variable-length bit stream, and convert the bit stream to keyboard codes. The client computing device selectably transmits the keyboard codes to the host computing device.
Claims20
A remote data capture system, comprising:
- a host computing device;
- a client computing device communicatively coupled to the host computing device;
- and
- a capture device coupled to the client computing device, the capture device having a sensor and being configured to:
- receive an electrical input signal from the sensor,
- convert the input signal to corresponding input data having a predetermined format,
- compress the input data to a variable-length bit stream, and
- convert the bit stream to keyboard codes,
- the client computing device selectably transmitting the keyboard codes to the host computing device.
A system for compressing electronic signatures, comprising:
- a client having:
- a stylus;
- a sensor panel arranged to generate an electrical input signal in response to movement of the stylus thereupon;
- a client computing device, and
- a controller configured to receive the input signal from the sensor panel, convert the input signal to corresponding input data, compress the input data to a variable-length bit stream, convert the bit stream to keyboard codes, and forward the keyboard codes to the client computing device;
- a host computer configured to receive the keyboard codes from the client computer;
- and
- an electronic communication system intermediate the client computer and the host computer.
A method for compressing electronic signatures, comprising the steps of:
- generating an electrical input signal in response to movement of a stylus upon a sensor panel;
- measuring coordinates corresponding to the electrical input signal;
- scaling the coordinates;
- differencing the scaled coordinates;
- encoding the differenced coordinates with special codes to generate coded data;
- compressing the coded data;
- and
- encoding the compressed data into a predetermined format.
