Optical sensor methods and systems for detecting the edge of an object are disclosed. An optical sensor having dual equal area active regions can be provided, and a uniform light source located opposite the optical sensor, such that an occlusion of light from the uniform light source provides location determination data of an object via the optical sensor regardless of the direction of motion of the occlusion relative to the dual equal area active regions thereof.

Opto-electronic transmissive edge location sensor

A method and system for detecting a magnetic field utilizing a magnetoresistor of a magnetic sensor is disclosed. A normalized magnetoresistance associated with the magnetoresistor can be calculated such that the magnetoresistor comprises an initial magnetization direction thereof. The magnetic field is generally permitted to exceed an ability of the magnetoresistor to remain pointed in the initial magnetization direction, thereby enabling the magnetoresistor to experience a magnetization reversal thereof. The normalized resistance can be placed into a new state in response to the magnetization reversal thereof, thereby permitting the normalized resistance to be utilized as a switch thereof and allowing the magnetic sensor to detect changes in the magnetic field associated with the magnetoresistor.

The specification discloses a control module having circuitry for generating control and timing signals and for receiving digital data. A plurality of sensor modules are connected to the control module and each contains devices for sensing various physical characteristics, such as water level, rainfall or the like. In response to control signals generated by the control module, each of the sensor modules is operable to input digital data representative of the sensed physical characteristics to the control module. A recorder is connected to the control module and includes a removable recording cassette for recording the digital data transmitted from the sensor modules. The recorder also records the identification of the sensor module transmitting data, along with the calender day and the time of day that the data was transmitted.

The specification discloses a digital method for measuring the volumetric flow rate of a flowing fluid, utilizing the change in electrical conductivity produced in a fluid by the introduction of a predetermined quantity of electrolyte. A temperature sensitive conductivity probe has an oscillator with an output signal frequency directly proportional to the conductivity of the fluid flowing between the electrodes of the probe. The conductivity probe is disposed in the fluid downstream from the point at which the electrolyte is introduced to alter the electrical conductivity of the fluid. The circuitry measures the increase in conductivity caused by the electrolyte during the period of time it takes the electrolyte to pass the conductivity probe and subtracts the integral of normal conductivity to determine the integral of conductivity produced by the electrolyte. The volumetric flow rate of the fluid is calculated directly by dividing a flow constant, determined by the number of equivalents of electrolyte introduced, by the integral of the conductivity. A digital display provides direct indication of the flow rate. The device can also determine whether too much or too little electrolyte has been introduced for accurately measuring the volumetric flow. The conductivity probe signal can be converted to indicate and display directly the conductivity of the fluid to visually determine the width of the conductivity peak. The period of time for integrating the change in conductivity produced by the electrolyte in solution with the field can be adjusted and the circuitry can be reset for additional measurements.
