An address at which a writing error occurs is held, and after a completion of a series of writings, the data of the held address is read. Then, a faulty-block processing is performed only for the addresses, for which it is determined that retry of writing is required, thereby preventing an increase of faulty-blocks. This can suppress the problem that when a writing is performed in a particular flash memory, a writing error frequently occurs and a large number of faulty blocks occur.

A glasses type display that is connected to an information communication terminal via a wire line or a wireless line, in which the operation by the user is made simple by preventing error operation and the power consumption is decreased by not consuming the unnecessary power, is provided. The glasses type display provides lenses, a main frame, side frames, a microphone, a speaker(s), open and closed state detecting sensors, wearing state detecting sensors. When the user opened the side frames, the open and closed state detecting sensors react, and the wearing state detecting sensors become the on state. When the user put on the glasses type display, the lenses automatically become the on state by that the wearing state detecting sensors detected the wearing state. And when the reaction from a part of the wearing state detecting sensors was turned off, caused by some vibration, the lenses are not immediately turned off. Therefore, an error operation is avoided. When the side frames were closed, the lenses were turned off automatically by the operation of the open and closed state detecting sensors. Therefore, the unnecessary power consumption is avoided.

A mitigation enablement module for a computer that improves application reliability. When performing memory management operations, the mitigation enablement module and associated memory manager selectively use mitigations that are intended to prevent an application bug from cause an application error. The memory manager may selectively apply mitigations for each of one or more applications based on the likelihood that such mitigations are successful at preventing bugs from causing application errors. The likelihood is determined from historical information on whether the mitigations, when applied, prevented bugs from causing memory operations that could cause application errors. This historical information can be gathered on a single computer over multiple invocations of the application or may be aggregated from multiple computers, each invoking the application. The determined likelihood may then be used to determine whether or for how long to apply the mitigation actions for memory operations requested by the application.

Whether the comparison value of temporarily stored data which is read out from a flash memory by a host system exceeds a threshold value related to a bit error or not is checked, and if the comparison value exceeds the threshold value, the temporarily stored data which is read out is rewritten into the flash memory. If the temporarily stored data has an error, the error is corrected by an error correction part and then the data is rewritten. The threshold value includes, e.g., the number of readouts, the number of bit errors and the number of accumulated occurrences of bit errors. The present invention is suitable for prevention of bit errors due to read disturb and can recover the bit data which changes with time, and therefore makes it possible to improve the reliability of the flash memory by preventing occurrence of bit errors.

Method and apparatus which prevents or at least significantly reduces errors during dynamic TDD UL/DL configuration changes. Received downlink time division duplex subframes are monitored during a predetermined time window, wherein at least a portion of the subframes includes an uplink/downlink configuration indication. In response to not detecting an uplink/downlink configuration indicated by any of the uplink/downlink configuration indications in the monitored downlink time division duplex subframes, an average of the monitored uplink/downlink configuration indications is calculated. The calculated average is utilized in determining a time division duplex uplink/downlink configuration to be used.

A surface defect inspection apparatus is structured to add detection signals of multi-directionally detected scattered lights to detect a tiny defect and to individually process the respective detection signals to prevent an error failing to detect an anisotropic defect.

The technical scheme of the invention is a dynamic time bending distance fault section locating method based on time sequence compression. The method comprises the steps: carrying out the preprocessing of the fault record data collected by a feed line terminal device, wherein the preprocessing operation comprises the extraction of the initial value and extreme values of the record data and the changes of the record data, and obtaining a new time sequence of the record data; transmitting the time sequence to a main station, solving the similarity of zero-mode currents of two adjacent feed lineterminal devices via a dynamic time bending distance algorithm through the main station, and determining a fault section. The beneficial effects of the invention are that the data size, compared withan original time sequence, is reduced by a half or more, thereby greatly reducing the communication cost; for a high-frequency signal, the dynamic time bending distance algorithm is stronger in synchronization error prevention capability and signal amplitude response capability than a correlated coefficient method; the method provided by the invention is higher in robustness, and does not need the strict time synchronization.

The invention aims at providing an NC-operation error preventing technology. A standard calibration block is arranged on the worktable of an NC machine tool, an operating check procedure for checking block feed before a workpiece processing procedure is increased, so that automatic detecting can be realized for tools and coordinate system setting through simple system macro procedure calling, thereby avoiding economic loss caused by misoperation in the NC process. The development of error-checking subroutine is mainly based on application system parameters, system variables and counting and logic computing, breaking away specific processing parts, thereby having generality for all parts on a specific machine. Error-checking subroutines are stayed in the system of the CNC machine tool, thereby just simply calling is needed for processing any parts.

Provided are a method and an apparatus for accurately detecting positions of eyes in an input face image. The method includes extracting a symmetric face region from a face image based on magnitude and phase of gradient in each pixel of the face image; detecting available eye positions based on brightness information of the extracted face region; verifying regions around each of the detected eye positions with a classifier which determines whether an input image is an eye image using information obtained by supervised learning on sample images. According to the present invention, faulty eye detection is prevented by removing obscuring elements such as illumination, glasses and hair from an input face image. Also, eye coordinates can be extracted more accurately using an eye classifier.

The present invention provides a highly sensitive inspection technology that prevents false detections. The present invention includes means for detecting an image of an entire chip. Using this image, inspection regions are defined based on criticality. Detection sensitivities can be set for each of these inspection sensitivities. Alternatively, false detections can be eliminated in post-inspection processing by recording characteristic values used to evaluate defects, e.g., concentration differences, in the inspection results. Furthermore, by providing a system that allows sharing of inspection conditions and the like needed by multiple inspection devices, the time required for determining inspection conditions can be shortened and stability and reliability can be monitored.

Erroneous detection of a failure in spite of the absence of failure on the route on account of a communication delay is to be prevented. A node device detects a failure on the route to a remote node device is detected by a failure to receive a packet from the remote node device after the elapse of a determined detection time. The node device sets “remote system transmission interval x detection multiplier” to be a first detecting time on the basis of a packet transmission interval determined by negotiation with the remote node device. It also sets the sum of “remote system actual transmission interval x detection multiplier” and “tolerable delay time” to be a second detecting time. The first detecting time and the second detecting time are compared, and what is longer is determined as the detecting time to be applied to actual operation.

Systems and methods are provided through which compare instructions in computer code are eliminated partially resolving the predicate of the compare instructions. Partially resolved predicates are used to reduce the number of compares generated during the prediction phase of the compiler. In a partially resolved predicate, the predicate name is defined along the same paths as the fully resolved predicate counterpart, but it can be used to guard a subset of the instructions of the fully resolved predicate name. A partially resolved predicate is generated for predicate names which are only valid in a restricted control flow region. One or more of the control flow edges are ignored when computing control dependence. The predicate name relies partially on the actual ignored control flow edge to prevent incorrect usage of the predicate name.
