Abstract: It concerns a method for delivering temporarily a plurality of software applications each based on respective contextual data, to one or more wireless mobile end-user devices (13), by using a single application called contextual engine pre-installed in said mobile devices (13), said delivery being limited to the immediate vicinity of specific locations comprising the steps of (i) receiving on a local device (9) located in the vicinity of one of said specific locations a remote request from one of said mobile end-user devices (13) located near said local device (9) for retrieving one of said plurality of applications related to its respective contextual data, (ii) receiving on said local device said application from a remote server (5), (iii) delivering automatically from said local device (9) exclusively said software application to said mobile end-user device (13) via a wireless connection (12), and (iv) displaying said application on said mobile end user device (13).

Abstract: A method & apparatus for conveying an ultrasonic sensor about an outer peripheral surface of a tube to perform a non-destructive evaluation thereof is disclosed. The ultrasonic sensor is mounted on a flexible tension link and the method involves extending the flexible tension link while urging an extended portion of the flexible tension link towards the outer peripheral surface of the tube at a plurality of locations along it's length, thereby causing the ultrasonic sensor to move through an arc in a direction circumferentially around the tube while maintaining ultrasonic coupling between the ultrasonic sensor and the tube.

Abstract: The purpose is to solve target problems in short calculation time certainly without describing algorithms that are data procedures on computers. As the solution method, because it is configured so that, when the initial values or variation values, which are used for constraint conditions with regard to target problems and the relevant constraint conditions, are set through Variable Value Setting 2, then Constraint Condition Extraction 3 extracts constraint conditions that are related to those variables, then Constraint Condition Calculation 4 searches for the solutions for each constraint condition one by one, and Variable Value Resetting repeats searching for the solutions for each constraint condition setting these searched solutions as new variables, so the course of solution searching becomes clear, and it becomes possible to surely reach the final solution and dramatically speed up computing, because each markedly simplified constraint condition has only to be solved.

Abstract: A device (1) and process providing an interface between a user (2) and an apparatus (3) which can be remotely controlled by infrared radiation (4). The device includes an infrared signal reception device (16) and at least one series connection (18) as well as a device which process infrared signals corresponding to the programmable apparatus, can code in ASCII and then store the infrared signals in a read-write memory (20) and process the signals coded in this way and/or stored data in order to carry out a specification application. The device also includes at least one individual sensitive sensor which can be actuated by the user and can trigger the emission of the infrared signals for the remote control of the apparatus from the processing device such that the specific application is carried out at least in part.

Abstract: A device and a method of interfacing between a user and an apparatus which can be remotely controlled by infrared radiation are disclosed. The device receives infrared signals and includes at least one serial link. Infrared signals corresponding to the programmable apparatus are coded into ASCII and the infrared signals are stored in a read/write memory. The coded signals and/or stored data are processed in order to carry out a specified application. Several individual sensors located at a distance from the box, respectively connected in a removable manner and by cabled link to the box, are actuatable by the user and are capable of triggering the transmission of the infrared signals for remotely controlling the apparatus.

Abstract: A method and a system for interactive dialogue between a user and a server includes an interactive device including a mechanism for sending data transmitted by the server as infrared signals decoded as hexadecimal character strings and receiving infrared signals. The system further includes a portable remote-control apparatus including a compact housing and a mechanism for receiving and transmitting infrared signals, a mechanism for storing in a read-write memory data corresponding to the signals transmitted by the device and received by the apparatus, a mechanism for displaying messages and a mechanism for manually controlling the transmission of infrared signals sent back. The message display mechanism is capable of displaying in real time and at locations determined by the device the messages derived from control instructions supplied by the device.

Abstract: A lightweight frame for stretching or blocking fabric material comprising elongated metal side frame elements detachably coupled together at their adjacent ends by a coacting pair of corner elements which are selectively expandably movable and contractibly movable relative to one another, so as to increase or decrease the frame size. Rotatable actuators coacting with the corner elements provide for the selective expansion and contraction of the corner elements relative to one another, to thereby cause said expansion and contraction of the frame. By providing a series of different lengths of side frame elements, substantially different frame sizes can be expeditiously provided. The paired corner elements and the coacting side frame elements have means thereon for rapidly detachably coupling the frame and corner elements together, as well as for rapidly securing fabric material to and removing fabric material from the frame proper.

Abstract: An adaptive control for a dynamic system or process which can be described mathematically as having dominant eigen values and which utilizes the phase response variation with frequency and more precisely uses the rate of change of phase with frequency to measure dynamic characteristics of the system or process and by comparison with known optimum values of rates of change of phase based on a criterion as herein defined determines the changes required to controlled parameters or to a controlling computer in order to achieve and maintain optimum or near optimum performance of the dynamic system or process.
