The control section performs a write operation, in synchronism with a clock signal, for transferring write data to one of the plurality of memory devices, utilizing: (i) an identification information transmission period during which the control section sends the identification information of a single memory device to all of the plurality of memory devices through the data line to select the single memory device; (ii) a write data transmission period during which the control section sends a single set of write data having a prescribed size to the selected single memory device; and (iii) a response period during which the selected single memory device responds to the control section with a response signal indicating presence or absence of communication error in relation to the received set of write data. Communications between the control section and the selected memory device during the write data transmission period and the response period are repeatedly performed for each transmission of one of plural sets of write data having the prescribed size. The control section sets a frequency of the clock signal during the response period to a lower value than that of the clock signal during the write data transmission period.

An authorization system and computer program for provision and process of a personal identification number (PIN) via a short-message-service (SMS) text message to a mobile communication device. The authorization system and computer program receive a communication from the user indicating a one-time-authorization mode. The authorization system and computer program retrieve information from a point-of-sales location and process a unique identifier for the mobile communication device. A text message is sent to the identified mobile device. The message communicates a one-time-use PIN with required PIN return via the point-of-sales system. The confirmation is processed, which authorization only occurring after confirmation. The PIN response period is voided after a short time, further improving security of the transaction.

A system is provided for responding to chemical, biological and / or nuclear attacks in large areas such as cities, states and nations. The system protects the public before significant exposure occurs, utilizing a preventive approach rather than a purely reactive approach. Modeling may be conducted to selectively position sensors for the on-going collection of real-time detection data, such as contaminant types and concentrations, weather conditions, terrain data, dispersion data and the like. The detection data is compared to background data and modeled data to detect unsafe contaminant levels and immediately activate a response system. The integrated modeling and simulation component may function to interface with real-time data from the sensors providing integrated real-time plume depiction, prediction, and verification, as well as real-time response and mitigation. This is testable and serves as an advanced redundant scientific control. The response system may implement a variety of measures, including, but not limited to, medical response procedures for emergency rooms and hospitals, warning alarms, instructions for personal protection, sealing of buildings, introduction of positive pressure in buildings, and introduction of clean air in confined spaces. During the response period, actual affects of the contaminant release may be determined, such as symptoms developed by people, animals and plants, treatments given to patients, medication consumption, assessments of environmental damage and remediation thereof, etc. The response to the contaminant release may then be modified based on the determined actual affects of the contaminant release.

A method for controlling a servo for an actuator that applies a force to a piston that reciprocates in a cylinder of a free piston engine having axially-aligned cylinders and a pair of mutually connected pistons that reciprocate in the cylinders. The servo has a first state at which an energy source is connected to the actuator for developing the actuating force. The length of a response period for the actuator force to reach a desired magnitude after applying a control signal to the servo is determined. The length of a period for the piston to reach a desired position where the actuator force will reach the desired magnitude is determined. The servo is switched to the first state when the length of time for the piston to move from its current position to the desired position reaches the length of the response period.

A signal delay time measurement device outputs, to a sound space, a measurement signal sound corresponding to a measurement signal such as a pulse signal, and obtains a response signal indicating a response thereof. By comparing the response signal with a predetermined threshold, the signal delay time measurement device measures a signal delay time in the sound space. The signal delay time in the above-mentioned sound space includes a delay time other than the delay time caused by a transmission of a signal sound to the sound space, and the response signal cannot theoretically reach the signal delay amount calculating unit during the delay time. Therefore, the delay time calculating unit does not perform the comparison in a no-response period in which the response signal has not reached the delay time calculating unit yet. Thereby, it can be prevented that the signal delay time is erroneously calculated by an effect of a background noise during the no-response period.

Revision of a part specification document, such as a drawing, a part specification, or a bill or materials, prompts execution of an automated notification process. A unique part number associated with the revised part specification document is employed in searching open purchasing documents for purchase orders or request for quotes containing the part number. Electronic mail addresses for outside supplier contacts are kept in the database and linked to the supplier master of the open purchasing documents containing the part number. An electronic mail notification of the part specification document revision is generated and transmitted to each electronic mail address identified as being associated with an open purchasing document containing the subject part number. The revision notification includes a link to the revised part specification document to enable the outside supplier to access the document and review the revisions. A response period during which the outside supplier is expected to access the revised document may be set, with an alert being generated if one or more outside suppliers receiving the revision notification fails to review the changes within the selected response period.
