A network session recording and parsing system (“SRP System”) captures direct user interactions passed between the web server and a browser, the SRP System and information from the web site's server-side application layers. In one embodiment, the SRP System includes two main components, data recording hooks and a parser. The SRP System includes a data recording hooks library that provides the ability to implement a dynamic, web-based application and gather a wide-range of user session history information. The SRP System parser analyzes the logged information from the data recording hooks and re-creates a history, with a desired level of contextual detail, of every individual user's session. In one embodiment, the SRP System embodies a flexible design system that allows a designer to customize the type of information recorded. An embodiment of the data recording hooks provides a virtually unnoticeable impact to browser-Web server request and response times.

An oxygen concentration detector under a temperature control for an internal combustion engine. An oxygen sensor of a critical current type is held between a gas under test and a reference gas, in the vicinity of which a heater is located for heating up the oxygen sensor in a sensor activating temperature range. A first voltage is applied for a positive bias control to the oxygen sensor during a first period, and a second voltage is applied for a negative bias control thereto during a second period. Electric current flowing through the oxygen sensor is detected during the first period in order to detect the oxygen concentration in the gas under test. The current value is also detected during the second period in order to detect and maintain constant the internal electric resistance of the oxygen sensor by controlling the heater heating output.
摘要:
A fuel injection system in which the valve control pulses are generated on the basis of information regarding the engine rpm and the combustion air flow rate and in which the air flow rate is measured by a baffle plate and a position sensor. When the throttle is abruptly closed, the inertia of the air and of the baffle plate prevents a precise measurement and an overly lean fuel mixture may be admitted. Accordingly, the apparatus of the invention is sensitive to the rate of change of the signal from the baffle plate sensor and when that rate is too great, additional current is fed to a multiplying circuit, thereby extending the control pulse length and increasing the amount of fuel fed to the engine.
