A mobile device communicates with a base station according to a communication protocol, the communication protocol having a first message for signaling a readiness of the base station for a normal login operation of the mobile device with the base station and a second message for signaling a readiness of the base station for an ad-hoc login operation of the mobile device with the base station, so that the ad-hoc login information of the ad-hoc login operation can be distinguished from the normal login information of the normal login operation. To this end, the mobile device has a receiver, an interpreter and a processor, which is formed so as to perform the ad-hoc login operation when the readiness of the base station for an ad-hoc login operation is signaled.

A one-arm data center topology routes traffic between internal sub-nets and between a sub-net and an outside network through a common chain of services. The data center topology employs layer 4 services on a common chassis or platform to provide routing and firewall services while reducing the number of devices necessary to implement the data center and simplifying configuration. Load balancing is provided by a load balancing device. In the one-arm topology, policy based routing or client network address translations or NAT pushes traffic to the CSM.

A method for position tracking includes placing an internal reference probe in a reference location within a heart of a subject, and collecting and processing first location coordinates of the internal reference probe during one or more respiratory cycles so as to define a range of the location coordinates corresponding to the reference location. An active device is inserted into the heart, and second location coordinates of the active device are collected. The first and second location coordinates are jointly processed so as to find relative location coordinates of the active device in a cardiac frame of reference. When a deviation of the first location coordinates from the range is detected, the relative location coordinates are corrected to compensate for displacement of the reference probe from the reference location.

A communication bus suitable for use in a hazardous area of a process plant includes a first transmission path adapted to communicate electrical signals in a first direction, and a second transmission path adapted to communicate electrical signals in a second direction. A safety device is coupled to each of the first and second transmission paths and includes a control unit adapted to detect a fault condition associated with the communication bus. The safety device further includes a switch unit adapted to interrupt the flow of electrical signals along each of the first and second transmission paths in response to the detected fault condition. In this manner, the detection circuitry of the communication bus automatically reduces or prevents the occurrence of sparks or arcing in the event of a fault condition associated with the communication bus.

The invention relates to a system and a method for website content joint recommendation, wherein the system consists of web page embedded codes, an access log, a user information table, a web page information table, a representative word recommendation table, an association recommendation table, a personality-oriented recommendation table, a website information management module, a representative word recommendation table generation module, an association table generation module, a personality-oriented recommendation table generation module, a representative word recommendation module, an association recommendation module, a personality-oriented recommendation module, a recommended control module and a recommendation display module; the invention can automatically extract representative words of each web page, arranges recommendation order of other web pages with the core of one recommendation word, comprehensively utilizes current access information of the user, personal access historical information of the visitor and overall access information of website access to intelligently recommend the content of the website. The system and the method have higher automation and intelligence, can predict and estimate the direction of the next browser of the visitor more accurately, provide content recommendation for the visitor of the website, increases 'stickiness' of the website, and improve pageviews of the website greatly under the conditions that investments of ads of the website are not increased, and the original content of the website are changed.

A battery case for a mobile device is provided comprising a case, electrical components, a port, and an aperture size to contain at least one rechargeable battery. Also provided is a charger including a mount to receiving a rechargeable battery. The rechargeable battery may be configured to fit inside of the battery case. The charger may be figured to fit inside of the battery case.

The invention relates to a novel non-pressure irrigation rig. The water outlet valve of a water supply tank is opened, irrigation water flows into a water level control tank, when the water level of the tank is higher than h1, an intake tube is submerged, air suction is changed into water inflow until the water level in the intake tube is equal to the water level in the water supply tank, the irrigation water does not flow into the water level control tank, the water level of the tank is stabilized at the water level slightly higher than h1, the irrigation water enters into a filling area at the upper part in a U-shaped slot by virtue of a permeable cover plate and a sand inverted filter from the bottom in the U-shaped slot of the irrigator, a soil saturation water layer which is at the same height of the water level of the water level control tank and is lower than the upper edge of the U-shaped slot, water of the saturation water layer rises to the root layer of a crop in a capillary water way, a crop consumes water to cause the water level of the water level control tank to be lower than h1, the intake tube comes out of water surface, air is sucked in air bubbles, the irrigation water flows into the water level control tank, the water level rises to submerge the intake tube again, the crop consumes the water to cause the water supply process to be repeated, the output of supplying water is increased or reduced along with water consumption, irrigation is adaptive, and the irrigation rig is simple to operate and is convenient to use.

A wind energy system comprising a wind turbine comprising a cowling surrounded by a diffuser and a plurality of inner rotor blades located inside of the cowling that rotate about an inner hub, a plurality of outer rotor blades positioned between the diffuser and the cowling that are counter-rotating relative to the plurality of inner rotor blades, a drive mechanism located within the inner rotor hub, a dynamic telescopic tower, and a tower support that connects tne wind turbine to the dynamic telescopic tower.

A putter head prevents a ball from sliding over a green while maintaining golfers' preferred hitting feel and roll of the ball. A face insert fitted in a face of the putter head has an outer layer which serves as a ball-hitting surface and an inner layer which is located on an inner side of a head body. A smash factor of a second polymer material forming the inner layer is greater than a smash factor of a first polymer material forming the outer layer. Two types of groove, grooves of a first groove group and grooves of a second groove group are formed in an external surface of the outer layer. The grooves of the first groove group may be 0.25 to 1.6 mm wide and 0.05 to 0.5 mm deep and the grooves of the second groove group may be 0.075 to 0.5 mm wide and 0.025 to 0.1 mm deep.

A radiation imaging apparatus including: a plurality of conversion elements being arranged in one-dimensional or two-dimensional array on a substrate, and converting an incident radiation into an electric signal; and a light source for calibration emitting a light to the conversion elements. During a light output adjustment period for driving the light source, a driving level of the light source is adjusted based on a control signal produced by comparing an output signal from a conversion element with a predetermined initial output signal.

A wellhead or Christmas tree seal assembly that forms a metal-to-metal seal between inner and outer wellhead or Christmas tree members. U-shaped metal seals having legs that face in opposite directions, are bonded to a wiping element. During installation of the seal assembly, the ends of the seal legs seal against the wellhead members and the wiping element compensates for defects on the surfaces of the wellhead members. The wiping element can be of an elastomer, metallic, or intercalated graphite material.
