Abstract: A log acquisition method is provided that allows a processing log of software to readily be acquired and reduces the man-hours needed for analyzing a bug. The log acquisition method is a method for acquiring a runtime log of a program including a function, comprising the step of changing the address of the function loaded to the address of a function for log acquisition and selecting the function, wherein the function for log acquisition comprises the steps of: calling the function the log of which is to be acquired to cause a predetermined process to be executed, receiving the result of the execution, and passing said result to said program, recording given information when calling the address of the selected function, and recording given information when receiving the result of the execution of the selected function.

Abstract: An information processing apparatus executes a first module, a second module, and a third module for mediating a call from the first module to a function in the second module and obtaining the log of processing in the second module in response to the call. The apparatus obtains the log from the third module, extracts, from the obtained log, attribute information of functions and identifiers assigned to the functions, and determines, on the basis of attribute information of a first function and a second function among the extracted functions, identifiers assigned to the first function and the second function, whether processing in the second module has normally ended.

Abstract: In an information processing apparatus which executes a first module, a second module, and a third module for mediating a call from the first module to a function in the second module and obtaining the log of processing in the second module, the third module determines operation condition of the initialization processing when a call from the first module to a function associated with initialization processing in the second module is detected, executes the function associated with the initialization processing in the determined operation condition, and notifies the first module of the execution result.

Abstract: In an information processing apparatus for relaying a calling from a first module to a function inside a second module in software divided into a plurality of modules, the calling is relayed from the first module to the function inside the second module. A log in the second module corresponding to the calling is obtained. The log includes at least a write starting address of binary data and a data size thereof. An area where the binary data is written is determined based on the write starting address and the data size thereof. Whether or not writing into the decided area is permitted is determined. On the basis of the determination result, writing into the decided area of the binary data is controlled. As a result, writing into an invalid area of the log is prevented without modifying the software.

Abstract: An automatic weight detecting device is provided with a platform on which an object to be measured is placed, a supporting shaft for supporting the platform is rotatable and smoothly movable in the supporting direction. A driving motor rotates the supporting shaft, and an elastic member supports the supporting shaft. A load detecting device converts the load of the object, transmitted in the supporting direction of the rotatable supporting shaft through the elastic member into a given electrically physical amount and a weight detecting circuit integrates to obtain the average of the electrically physical amount while the shaft rotates, so that the weight of the object is detected.

Abstract: The invention detects the weight of an object by detecting the change in electrostatic capacity due to a change in the distance between electrodes caused by deflection of flat plates, by using a pressure sensitive sensor having flat plates composed of two elastic insulators stuck together across a proper gap and extending parallel to one another, with electrodes provided at the confronting sides of the flat plates, and by transferring the load of the object to be measured to the sensor through a load support. The gap between the electrodes of this pressure sensitive sensor is enclosed, and a hole is provided to allow air to pass into and out of the gap. Furthermore, the surface of the pressure sensitive sensor is coated with a water-repellent substance to eliminate current loss due to dust or dew deposited on the surface of the electrodes. As a result, the weight may be measured accurately without being effected by temperature changes or humidity.
