International Classification:

G09G005/08

US Classification:

345/163000

Abstract:

Movement of a mouse or joy stick is detected by optically tracking with a navigation sensor the change in position of the micro-texture on a ball instead of using the ball to actuate shaft encoders. The interior of the mouse or joy stick is an optically controlled environment where the external ambient illumination is excluded, the angle, and intensity of a desired illumination is established once, and the only surface to be imaged and tracked is a part of the ball. As the ball rotates a portion of the old image passes from view as a new portion emerges. Consecutive images are represented internally within the optical tracking mechanism as arrays of pixels, and the tracking mechanism tolerates the disappearance of some pixels along one side of the field of view whilst other pixel appear from the other side of the field of view. Pattern matching of unchanged pixels determines movement. The pattern described by the new pixels need not have any relationship whatsoever to that represented by the disappearing pixels. That is, the ball need not have either a known or a precision pattern upon its surface; the surface can have an arbitrary micro-texture. Any wear and tear to the ball, or dirt that gets on it, simply appears as micro-texture to the optical tracking mechanism. Since the micro-texture is expected to be arbitrary anyway, these phenomenon are of little concern, so long as they do not mechanically interfere with the motion of the ball.

Abstract:

An adaptable programmable calculator employs modular read-write and read-only memories separately expandable to provide additional program and data storage functions within the calculator oriented toward the environment of the user, and an LSI NMOS central processing unit, capable of handling sixteen-bit parallel binary operations, binary-coded-decimal arithmetic, sixteen-bit parallel input/output operations, two-level interrupt from up to sixteen input/output devices, and a direct memory access channel. The input/output units include a keyboard input unit having a full complement of alphanumeric keys, a magnetic tape cassette reading and recording unit capable of bidirectionally transferring programs and data between the calculator and a magnetic tape, a 32-character solid state output display unit capable of displaying every alphabetic and numeric character and many other symbols individually or in combination, and a sixteen-column alphanumeric thermal printer for printing results of computations, program listings, messages generated by the user and the calculator itself, and error conditions encountered during use of the calculator. All of these input/output units are included within the calculator itself. Many other external input/output units may be employed with the calculator.

US Classification:

Abstract:

An adaptable calculator is provided by employing five MOS/LSI circuits interconnected by a multiple line bus system. They include (1) a read-only memory circuit group; (2) a control and timing circuit; (3) an arithmetic and register circuit; (4) a data storage circuit; and (5) an input/output (I/O) circuit. Input and output units include a keyboard input unit and an 18-column output printer unit. An optional LED display unit may be plugged into the calculator mainframe. The keyboard input unit includes an AUTO DECIMAL POINT key for selecting an automatic decimal point mode of calculator operation in which the calculator automatically places the decimal point at a specified location in all entered data. Thus, the operator need not manually enter the decimal point in entered data. The calculator may be operated manually by the user from the keyboard input unit or automatically by a program stored in the calculator memory.

They include (1) a read-only memory circuit group; (2) a control and timing circuit; (3) an arithmetic and register circuit; (4) a data storage circuit; and (5) an input/output (I/O) circuit. Input and output units include a keyboard input unit and an 18-column output printer unit for printing intermediate results of calculations, entered data, arithmetic operators, and diagnostic notes. The keyboard input unit includes a PERCENT key that may be employed in combination with any of four arithmetic operator keys. The calculator may be operated manually by the user from the keyboard input unit or automatically by a program written in user-level language and stored in a plug-in read-only memory unit (ROM), a plug-in programmable read-only memory unit (PROM) or a read/write memory unit associated with a plug-in magnetic card reading and recording unit.

Abstract:

An adaptable programmable calculator employs modular read-write and read-only memories separately expandable to provide additional program and data storage functions within the calculator oriented toward the environment of the user, and an LSI NMOS central processing unit, which includes the capability of bidirectionally transferring information between itself and various input/output units. The input/output units include a keyboard input unit having a full complement of alphanumeric keys, a magnetic tape cassette reading and recording unit capable of bidirectionally transferring programs and data between the calculator and a magnetic tape, a 32-character solid state output display unit capable of displaying every alphabetic and numeric character. The calculator employs a natural algebraic program language that allows the user to enter lines of one or more alphanumeric algebraic statements into the calculator from the keyboard input unit while visually observing each line as it is entered to check for errors therein. The user may immediately execute each entered line or store that line as part of a program in the read-write memory, may subsequently recall the executed or stored line so that it may be reinspected, and, if necessary, edited and re-executed or re-stored, thereby automatically replacing the previously stored line.

Abstract:

A process for the recovery of substantially pure zirconium values from zircon sand which also contains Ra, U, Hf, Pb and other metal values, comprising contacting zircon sand in a chlorinator with a chlorination medium to form an off-gas stream containing chlorides of Zr, Hf, Si, and tract U. The off-gas stream is passed to a condenser to remove volatile Si chlorides and thereby provide a product stream containing condensed chlorides of Zr, Hf and tract U, treating the product stream in acidic aqueous medium in a separation stage to separate the principal Hf values from the principal Zr values. Adjusting the pH of the resulting effluent to between about 3 to about 7 in a second stage to precipitate the trace U values. The residue stream is treated by (A) leaching with an acidic aqueous system to solubilize the trace Ra, Pb and other metal values while settling out the unreacted zircon sand and chlorination medium, and contacting the resultant leach liquor first with Ba++ ions and then with SO. sub. 4 =ions to co-precipitate the barium and trace radium ions as a sulfate complex and the trace lead and other metal ions as their sulfates, or by (B) contacting at least a portion of the residue stream with an aqueous system containing CO. sub. 3 =, SO. sub. 4 =or PO. sub.
