A micro bubble generating system includes a shell having a well for retaining a first liquid to immerse an object. A micro bubble apparatus is provide to the shell for providing a pressurized mixture of a second liquid and a dissolved gas into the well so as to create a plurality of micro bubbles within the first liquid for engaging the object. One method of using micro bubbles includes providing a fluid mixture, including a saturated gas, to a fluid chamber connected a fitting; and producing a plurality of micro bubbles into a fluid. Another method of using micro bubbles includes providing a fluid mixture, including a saturated gas, into an air entrapment chamber; and producing a plurality of micro bubbles into a fluid.

Methods and systems for efficient query rewriting and the like are described here. One such described method comprises: offline mapping frequently-seen search queries to rewritten queries that may be better for searching; offline caching the mapping in a cache memory; and upon receiving a search query from a user similar to one of the mapped search queries, obtaining a corresponding rewritten query from the mapping in the cache memory based on predetermined conditions, and issuing a search of the rewritten query to the backend data system in order to avoid having to issue a search query to the backend data system twice while the user is online.

A protective assembly for an operating nut of an actuator for a valve in an underground pipe system is comprised of a guide assembly and a mounting assembly. A riser pipe is used to access the operating nut from above ground. The protective assembly maintains alignment of the riser pipe at installation and as the ground shifts over time. The guide assembly is formed of a guide structure and a mounting collar that juts outwardly from the guide structure forming a flange. The mounting assembly has a first portion for attaching the mounting assembly to the flange, and a second portion for attaching the mounting assembly to the actuator.

The present invention is directed to an excavator that is operable in manual and automatic modes and uses state machines to effect unit operations, rotationally offset swing actuators to rotate boom and cutter head, a fail safe hydraulic system to maintain gripper pressure in the event of a malfunction of the hydraulic system, differing position and pressure control functions in the hydraulic actuators, a kinematic module to effect pitch and roll adjustments, a cutting face profile generator to generate a profile of the excavation face, and an optimization module to realize a high degree of optimization of excavator operation.

A printing system accurately prints proprietary marks and selected colors. A dictionary of recognizable patterns and defined colors corresponding to the proprietary marks and selected colors is linked to a user interface wherein a user may designate a location within a document and at least one of the proprietary marks with defined colors from an accessible menu. A processor associates the defined colors with the image at the specified location and generates a printer signal representative thereof. Alternatively, the processor includes a pattern recognizer for identifying recognizable patterns within a document. The patterns have a likeness to defined patterns within a pattern dictionary and can be converted to the defined patterns for display or imaging.

A stirring hot plate for simultaneously heating and stirring a mixture includes a phase controlled motor that spins magnets which couple to, and thereby spin, a stir bar within the mixture. In addition to spinning the magnets, the motor includes an operational mode in which the motor is rapidly braked thereby quickly spinning down the stir bar. The stirring hot plate also includes a visual indicator to the user that the platform is hot-to-the-touch that is especially effective when the stirring hot plate is not in use.

Novel subsea excavation apparatus and methods that exert force between a subsea anchor point and an excavator using a subsea actuator. In some examples the subsea actuator is attached to an anchor point on the seabed and the excavator directly. In other examples, a guide frame is anchored to the seabed to provide anchor points fixed relative to the seabed and the subsea actuators are attached to the guide frame and the excavator. In further examples, the subsea actuators can be attached to the excavator through a carrier frame or other excavator guides rather than directly to the excavator.
摘要:
A method to mitigate attack by an upstream service provider using cloud mitigation services. An edge detection device, which located at the subscriber's network edge, is able to communicate information via status messages about attacks to an upstream service provider. The service provider is then able to mitigate attacks based on the status messages. There is a feedback loop whereby the amount of dropped traffic by the service provider is added to the network traffic to keep the mitigation request open and prevent flapping. Likewise, the detection device includes time-to-engage and time-to-disengage timers to further prevent flapping.
