Tendon-driven endoscope and methods of insertion

A steerable, tendon-driven endoscope is described herein. The endoscope has an elongated body with a manually or selectively steerable distal portion and an automatically controlled, segmented proximal portion. The steerable distal portion and the segment of the controllable portion are actuated by at least two tendons. As the endoscope is advanced, the user maneuvers the distal portion, and a motion controller actuates tendons in the segmented proximal portion so that the proximal portion assumes the selected curve of the selectively steerable distal portion. By this method the selected curves are propagated along the endoscope body so that the endoscope largely conforms to the pathway selected. When the endoscope is withdrawn proximally, the selected curves can propagate distally along the endoscope body. This allows the endoscope to negotiate tortuous curves along a desired path through or around and between organs within the body.

A Conduit Having a Cable Therein

A method of suspending an electric submergible pumping system within a wellbore includes inserting an electric cable within a conduit, such as coiled tubing, before the conduit is deployed downhole. The electric cable is inserted into the conduit at the surface and is permitted to buckle in a manner so that the electric cable buckles and uniformly contacts an interior surface of the conduit at a plurality of locations along the entire length of coiled tubing to prevent longitudinal movement of the electric cable within the conduit. An electric submergible pumping system is then connected to the conduit, and the electric cable is connected to an electric motor of the electric submergible pumping system. The electric submergible pumping system and the conduit are inserted into the wellbore.

Database backup system and backup method and slave database server of database backup system

The invention discloses a database backup system and a backup method and a slave database server of the database backup system. The system comprises a master database server, the slave database server and a storage node cluster. The master database server is used for maintaining a database, the slave database server is used for backup of the database and transmitting a backup result after the backup result is obtained, the storage node cluster is based on the HDFS (Hadoop distributed file system) technology and comprises a storage control node and at least one storage node, and the storage control node is used for receiving the backup result transmitted from the slave database server and is responsible for managing backup file distributed storage of the various storage nodes. As the backup result is transmitted to the storage node cluster based on the HDFS technology to store backup files, the storage control node can comprehensively manage and adjust storage of the backup files according to storage space of the various storage nodes, the backup result is uniformly stored in the various storage nodes in a distributed storage mode, and utilization rate of the storage space can be increased in a database backup process.

Pressure Measuring Device

A pressure measuring device suitable for disposition in a chamber of an internal combustion engine. The pressure measuring device has a housing, a force transmitting element that is effectively connected to a pressure sensor, and a sensor cage that surrounds the pressure sensor. The sensor cage is connected to the housing by a circumferential weld seam only at one connection segment of the housing. In this way, it is possible to achieve a defined pre-tensioning of a metal diaphragm that is connected on the one hand to the sensor cage and on the other hand to the force transmitting element.

Precise self-centering chuck suitable for super-large workpieces

ActiveCN105772771AGood synchronizationSame output torqueChucksNumerical controlEngineering
The invention relates to a precise self-centering chuck suitable for super-large workpieces. The precise self-centering chuck suitable for the super-large workpieces comprises a chuck body and a plurality of jack catch mechanisms arranged on the chuck body in a sliding mode. A jack catch driving mechanism is further arranged on the chuck body and comprises a numerical control moment motor, a plurality of transition gears, a plurality of double-enveloping speed reducers and a first gear. The inner circular surface and the outer circular surface of the first gear are provided with inner teeth and outer teeth correspondingly. The numerical control moment motor is provided with motor teeth. The multiple transition gears are all engaged with the motor teeth and the inner teeth of the first gear. The outer teeth of the first gear are engaged with second gears of the multiple double-enveloping speed reducers. The double-enveloping speed reducers drive the jack catch mechanisms to reciprocate to clamp or release the annular workpieces to be machined. The numerical control moment motor is used for sequentially driving the multiple transition gears and the double-enveloping speed reducers to rotate in a matched mode, so that the multiple jack catch mechanisms move inwards or outwards synchronously. The super-large annular workpieces are subjected to automatic centering clamping or releasing, and the clamping positioning accuracy is high.

Behavior Shaping System and Kits

A system for modifying and shaping behavior. The system comprises a number of components, which may be used individually or in combination with other components. A variety of kits comprising various components can be formed. Components include a progress pyramid chart to reward and reinforce positive and desired behaviors, a graduated restrictions chart and work-before-play chart to discourage undesirable behaviors, a daily responsibilities or daily routine chart may be used to clarify and strengthen daily family routines, a point-based or token-based system may be used to reward children for appropriate actions or behavior, a tether or leash used to teach self restraint, a series of school success charts or plans used to monitor school work (on a daily, weekly, and monthly basis), a gratitude jar, a series of life skills charts (including a learning chart, decision-making chart, anger management chart, communication chart, problem-solving chart, and goal-setting chart), a mission statement for the family, a vision or manifestation chart for use by a caregiver, and a family coat-of-arms. These charts may include color-coded clips that correspond to color-coded timers, which may be used to teach the concept of graduated restrictions. The timers are used to define break or “time out” periods, and the colors may indicate the severity of the restriction. The above components and kits can be presented and used in a variety of formats: a clipboard, poster, magnetic material, board, computer program, television, hand-held computer or laptop, mobile phone, personal digital assistant, MP3 or music device, iPod, or similar electronic device.

Internal winch for self payout and re-wind of a small diameter tether for underwater remotely operated vehicle

A cable containing an optical fiber is used to transmit data between an underwater remotely operated vehicle (ROV) and a support vessel floating on the surface of the water. The ROV stores the cable on a spool and releases the cable into the water as the ROV dives away from the support vessel. The ROV detects the tension in the cable and the rate that the cable is release from the ROV is proportional to the detected tension in the cable. After the ROV has completed the dive and retrieved by the support vessel, the cable can be retrieved from the water and rewound onto the spool in the ROV.
