Abstract: A 3 state BiCMOS output buffer (100) with power down capability has been provided. The buffer includes an input stage (102), responsive to an input signal, an output coupled to both a pull-up driver (114), and an output pull-down driver (116) wherein the drivers provide an output signal at an output of the buffer in response to the input signal. Additionally, the buffer includes a power down sense circuit (108), coupled to a power supply node (118), for turning off an output pull-up transistor (214) when the power supply node is powered down and thus eliminating leakage paths within the buffer. The buffer also includes a noise limiting circuit (112) for slowing down a high to low transition at the output of the buffer thereby reducing the switching noise of the buffer while not affecting the overall speed of the buffer.

Abstract: The present invention includes an input buffer circuit (10) having sleep mode and bus hold capability. An input section (11) of the buffer circuit is operated from an operating voltage which is lower than a supply voltage of the buffer circuit thereby minimizing the static power dissipation. Sleep mode circuitry (15, 36, 38) is included for effectively disconnecting an input signal from the rest of the buffer circuit thereby minimizing dynamic power dissipation. Bus hold circuitry (40) is included for holding the logic state appearing at an output of the input buffer circuit when the input signal is removed thereby further reducing the static power dissipation.

Abstract: A plurality of transistors (22, 23, 27) are utilized to provide a low noise high-to-low transition (40) on an output (19) of a circuit (10). The transistors (22, 23, 27) are sequentially enabled to vary a rate of change of output current thereby minimizing noise created by the high-to-low transition (40). A first transistor (22) is enabled to provide a low rate of change. Subsequently, a second transistor (23) is enabled to provide a higher rate of change. Then, just prior to disabling the second transistor (23) a third transistor (27) is enabled to provide a d.c. level.

Abstract: The present invention includes a circuit having an input section that is operated from an operating voltage which is lower than a supply voltage of the circuit. The operating voltage is established so that the operating voltage minus the voltage of a high level TTL signal is less than an upper level threshold voltage of the input section. The circuit couples the output of the input section to the supply voltage thereby increasing the voltage on the output of the input section to a voltage greater than the operating voltage. In addition, the circuit enables a current source during a portion of a low-to-high transition on an output of the circuit. The current source provides high current drive during the portion of the transition. Since the current source is only enabled during the portion of the transition, static power dissipation is minimized.

Abstract: A circuit for use in conjunction with an enable/disable gate of a three state logic circuit for disabling the outputs of the logic circuit during power up of the voltage supply to maintain a high impedance output state at the outputs of the logic circuits. The circuit includes a voltage level detector stage comprising a switching transistor that is held in a non-conducting state until the voltage supply reaches a predetermined potential after which the transistor is turned on and a pair of transistors configured as a current mirror with their bases coupled to the output of the switching transistor. The pair of transistors are turned on until the switching transistor is turned on to provide sufficient base current drive to a disable transistor of the enable/disable gate such that the logic circuit is disabled accordingly. An aspect of the invention is that the power up circuit draws little additional power during normal operation of the logic circuit.

Abstract: A template-matching adaptive control system for welding comprising noncontacting means for sensing the lateral profile of a weld joint while the welding electrode moves laterally across the joint, means for comparing the sensed lateral profile to a predetermined reference profile or "template", and means for adjusting a welding parameter, such as the center of oscillation for tracking, the width of oscillation, and constant fill control, in response to the results of the comparison. The comparison between the sensed lateral profile and the template is based upon a mathematical criterion of the degree of match therebetween. One disclosed embodiment performs control based upon finding the closest match between the sensed lateral profile and a plurality of different templates. Another embodiment performs control by making adjustments related to the value of the mathematical criterion. The disclosed embodiments employ programmed microprocessers to accomplish the template matching.
