Abstract: A method and system for monitoring and predicting the health of electro-mechanical systems and components includes collecting data for a fixed pattern of actuation of such system or component. This data is used to build statistical models that correspond to a normal state of the system or component. New measurements are compared to this model in order to monitor the health of the system or component. The comparison can be made using a distance calculation. The combination of new measurements with historical data provides the prediction for future health states of the system or component.

Abstract: Heterocyclic compounds incorporating a [1,3]oxazine ring may be used to make chromogenic materials. These molecules switch from a colorless state to a colored form upon addition of either acid or base. In both instances, the [1,3]oxazine ring opens in response to the pH change forming an indolium cation, after the addition of acid, or a phenolate anion, after the addition of base. Alternatively, the switch may occur in response to a change in electrical current or potential or a change in temperature. Chromophores absorb in the visible region of the electromagnetic spectrum. Hence, their formation translates into the appearance of color. These processes are fully reversible and the original colorless state can be regenerated by switching the pH back to neutral. Thus, these halochromic compounds can be used to develop displays, filters, indicators, lenses, sensors, switches, or windows able to switch their color in response to pH changes.

Abstract: A shock bump (10) comprising a diverging nose (20) and a converging tail. The tail has at least one plan-form contour line with a pair of concave opposite sides (22, 23). The shock bump provides an improved shape with relatively low drag. Furthermore, the concave shape of the tail tends to promote the development of longitudinal vortices which can reduce shock induced buffet at certain operating conditions.

Abstract: Transaction requests requesting a service from the slave device are received from a master device at a transaction interface. The transaction requests are selectively issued to the bus system under control of an issue control circuit. A target outstanding transaction value N.x is received at a control interface. The target outstanding transaction value has an integer portion N and a fractional portion x. The issue control circuit controls the transaction interface to issue the transaction requests to the bus system in dependence upon the target outstanding transaction value so that a time averaged number of outstanding transaction requests corresponds to the target outstanding transaction value.

Abstract: A learning device changes each of multiple parameters to an increased side and to a decreased side with respect to a reference value set for each of the multiple parameters. The learning device calculates an approximation degree for each combination of the changes of the multiple parameters. The learning device performs update by using the combination of the changes providing the highest approximation degree among the approximation degrees as the combination of the updated reference values when an update end condition is not satisfied. The update end condition is a condition that the approximation degree at the reference values is higher than any of the approximation degrees after the change. The learning device decides the reference values as learning values of the multiple parameters when the update end condition is satisfied.

Abstract: There is proposed a method of side-loading content onto a mobile device, preferably using a WiFi connection, from a network content store and storing it on the device for viewing later. The method automatically determines when to delete stored content, and more importantly, what content should be transferred over the network in the first instance. The system comprises a content manager which takes into account various parameters to determine what should be transferred and, if required, what should be deleted from the device. The parameters used include user profiles, size of a potential download, as well as available storage space on the device and the predicted duration the device will be in range of a wireless hotspot or broadcast network.

Abstract: The present invention relates to a method for preferentially breaking cross-links in a vulcanized rubber, thereby de-vulcanizing the rubber, by the use of a supercritical fluid, such as carbon dioxide. The supercritical fluid maintained at an appropriate solubility parameter, swells the vulcanized rubber to a state of equilibrium swell. The cross links become fully extended and under strain to hold the internal pressures caused by the solvent swelling affect of the supercritical gas. When equilibrium swell has been achieved, the pressure within the processing vessel is rapidly dropped to a predetermined level causing a degassing and expansion of the supercritical fluid that has been absorbed within the vulcanized rubber. The resulting three dimensional separation of the rubber molecules will put a further rapid strain on the cross links, causing them to break, thereby giving the affect of de-vulcanization.

Abstract: An electronic control unit performs a process that stores into a buffer selected diagnostic trouble codes (DTC) currently in a volatile trouble code storage by selecting, from among multiple codes, a code that is to be saved in an EEPROM, when an ignition switch of a vehicle is turned off. Further, the DTC stored in the buffer is written in the EEPROM. If the electronic control unit receives, from a scan tool, a command that instructs erasure of the DTC in the volatile trouble code storage, the above-described process is performed before erasing the DTC from the volatile trouble code storage.

Abstract: A reinforced panel (1) comprising: a composite skin (2); a plurality of stringers (3, 4) bonded to the skin; and one or more strain actuators (5), each positioned between an adjacent pair of stringers. A load is applied to the panel in the plane of the skin, and a local strain is applied to the skin by the strain actuators when the compressive load exceeds a predetermined threshold. This causes the skin to buckle and reduce interface stresses between the skin and the stringers.

Abstract: A method of wafer or substrate bonding a substrate made of a semiconductor material with a substrate made from a metallic material is disclosed. The method allows the bonding of the two substrates together without the use of any intermediate joining gluing, or solder layer(s) between the two substrates.

And an image into which the fog image and the color image have been synthesized is displayed as a game image.
