摘要： The pressure of the atmosphere is sensed by a pressure transducer which causes a resistance to vary. The variance of this resistor is converted to a variable frequency. The number of cycles of this frequency in a set amount of time is counted by a counter and displayed by a digital display. An up/down counter is loaded with the count of the last digital readout in the previous cycle and counts down the number of cycles in the frequency of the next reading and displays the difference on a digital display or activates a sonic output if the countdown is greater than the stored previous count.

摘要： A simple self-aerating container for small marine life which requires no power. The aeration rate is easily adjusted continuously and remains constant once set. At low flow rates, the container can be aerated over night, and the high flow rates can be used when there are a larger number of small marine life in the container, or when it is desirable to have them very active. The aerator consists of a tank with a hand pump, a simple pressure regulator, and a unique mass (air) flow regulator. The tank is also equipped with a spring loaded safety valve and a valve for filling the tank at a service station.

摘要： A Robotic Vision System for real time operation based on a luminous fiduciary code located upon a robot and an object the robot is to operate on. The luminescent code, when irradiated, locate the position of the object relative to the robot thus allowing placement of the fiduciary codes, on the object and the robot, into a predetermined desired position and orientation.
