Abstract: The invention is embodied in a computer including a memory and a memory protector responsive to a list of key memory locations containing information to be protected, the memory protector including (a) a write protection circuit—operating independently of the computer—which prevents any write requests specifying the memory locations contained in the list from being carried out, and (b) a manual protect enable switch for enabling and temporarily disabling the write protection circuit, thus allowing special or temporary access to the protected memory locations. The write protection circuit may be implemented as a programmed microprocessor with its program stored in a non-volatile read-only memory, or as a dedicated hard-wired logic circuit, such as a field programmable gate array. The list of key memory locations may be stored in a non-volatile memory accessed by the write protection circuit. More conveniently, the list is contained in a protected memory location (i.e.

Abstract: A glove worn on the hand of a computer operator provides a computer mouse function for a computer having a video display highlighted by a cursor, in which the apparatus senses the direction of movement of an element of a computer operator's body and transmits corresponding commands to the computer to move the cursor in the video display in a corresponding direction, whereby two-dimensional movement of the cursor reflects movements of the body element. In one embodiment of the invention, cursor motion is controlled by lateral motion of the operator's wrist and vertical motion of the operator's index finger, whereby movement of said cursor follows the direction of movement of the wrist and index finger. Click button on various fingers of the glove are activated by the thumb to provide mouse click functions.
