    A Tone Alarm Control function is provided in a baseband modem without any loss of information on the transmit spectrum. The principle which has been chosen to perform the Tone Alarm Control function on a baseband coded signal is to transmit a low frequency tone and to detect it remotely. This tone is sent: when a...

    Electronic tablets are used to record images of handwriting and drawings. This is done by recording periodically the x-y coordinate points obtained from the dynamic trace of a stylus moving over the tablet. An indication of pen up-down is also recorded and the coordinate points are generally recorded only when the...

    A fast and efficient means of moving data to and from I/O devices is shown in the figure. The Generic Block I/O Subsystem (GBIOS) provides an efficient means of moving data to and from adapters that support or carry data which can be blocked at a low level. The GBIOS also provides a common design approach for block...

    A method is described for the mapping of logical sectors to physical sectors on a magnetic disk which provides for a 2/1 interleave within a block and also provides additional interblock time. With some disk adapters the best interleave factor possible is 2/1. This allows 1 sector (512 bytes) time to unload the...

    A technique is described whereby the addresses of failed computer memory registers, involving correctable and uncorrectable multiple errors, are recaptured during error correcting operations. Also described is a memory refresh concept for handling dynamic memory refreshing when operations of infinite duration are...
