Title: Gas sensor with dual electrolytes
Inventor: CONSADORI FRANCO
IPC: G01N27/49
Filed: 1999-06-25
Abstract: A highly accurate, long life, low cost gas sensor is disclosed, particularly useful for measuring oxygen in an environment. The gas sensor has a first, sensing electrode and a second, counting electrode. Dual electrolytes are electrically serially connected between the first and second electrodes. One of the electrolytes is an ion conducting solid electrolyte, the second is a liquid electrolyte. In response to an electric current an electrical characteristic is produced, and the electrical characteristic changes in response to changes in the concentration of a gas such as oxygen introduced at the first, sensing electrode. The solid electrolyte can be a perfluorinated polymer which advantageously controls the rate of the electrochemical reaction to give the sensor a long life without need for continuous recalibration. A dense liquid impermeable membrane may be positioned over the first electrode so that only gas reaches the first electrode and all gas that reaches the first electrode passes through the membrane. Advantageously, the solid electrolyte isolates the liquid electrolyte from the first, sensing electrode.  The liquid electrolyte may comprise an acidic solution, a basic solution or a salt solution.

Title: Method and apparatus for testing event driven software
Inventor: WINTERBOTTOM PHILIP STEVEN
IPC: G06F11/36
Filed: 1999-11-02
Abstract: A technique for testing event driven software. In accordance with the technique, the source code of the event driven software is directly converted to a automaton based model useful in verifying that the program code complies with the desired properties defined by the user. More particularly, the event driven system program code is translated into a target language for a particular model checker. Such a translation results in a model which contains statements directed at whether execution of the program code will affect the behavior of the event driven system. Thus, this model extraction process can be used as input to a logic model checker for determining whether event driven system complies with the desired correctness properties specified by the user. Advantageously, the model extraction process and application of the model checker occurs in a direct and dynamic fashion from the subject event driven system program code without the need for user intervention.

Title: Additional information superposing method, information signal copy control method, information signal output device and information signal recording device
Inventor: OGINO AKIRA
IPC: H04N1/387
Filed: 1999-11-12
Abstract: An image signal to be outputted is divided into two areas or a first area and a second area. In an electronic watermarking information forming section (WM forming section), a spectrum spread signal (electronic watermarking information) is formed as the first additional information so as to be superposed on the first area of the image signal. The spectrum spread signal is superposed on the first area of the image signal by an electronic watermarking information superposing section (WM superposing section). Moreover, in the case where the image signal is recorded on a recording medium, for example, the second additional information is newly superposed on the second area of the image signal. Thus, deterioration of the information signal is suppressed at minimum, and first and second additional information are superposed on the information signal to be capable of transmitting the information signal.
