Abstract: A sprinkler includes an axially extending, generally tubular sprinkler frame having an inlet located at a proximal end and extending toward a distal end. A plurality of pins are anchored to the sprinkler frame and extending distally. A fluid deflector is oriented in a first position in a non-operative configuration of the sprinkler and distally slidable along the pins into a second position in an operative configuration of the sprinkler. A thermal trigger is supported by the sprinkler frame in the non-operative configuration of the sprinkler at an axial position distal to the deflector. The sprinkler frame is configured to mount to a fire protection piping network.

Abstract: The present disclosure discloses a pathogenic microorganism sample collection and preservation device with a protection function, including a sampler and a preservation container; the sampler and the preservation container are both packaged by independent aseptic packaging bags. The sampler includes a sample collection mechanism, a holding mechanism, and a protection mechanism arranged between the sample collection mechanism and the holding mechanism. Before sample collection, the preservation container is sealed by an assorted sealing cover. The sample collection and preservation device of the present disclosure is convenient for holding and flexible adjustment of a sample collection angle. The protection mechanism between the holding mechanism and the sample collection mechanism plays a role of shielding, thus avoiding the problem of cross contamination.

Abstract: The present disclosure provides a female reproductive system sample collector, including a sampling device and an elution preservation device, where the elution preservation device is filled with an elution preservation solution, after sampling is completed, the sampling device is submerged in the elution preservation solution of the elution preservation device and sealed for preservation; the sampling device includes a sampling rod and a sheath; the sampling rod includes an operating rod, a straight rod brush and a ball head brush, an opening and closing cover corresponding to the ball head is disposed at a front end of the sheath, and the opening and closing cover includes four oscillating rods that are hinged with a front port of the sheath and the oscillating rods are connected through thin films. The present disclosure can collect cells or nucleic acids of uterus and ovaries in a uterine cavity, a sampling rod can deform in a shape along an outline of the uterine cavity.

Abstract: The invention discloses an integrated tumor resection instrument and a simulation training system. The resection device comprises an imaging system, a minimally invasive incision, a processor, an operating device, a resection executing mechanism and a positioning control device. The operating device is connected to the input end of the processor, the resection actuating mechanism is provided with a resecting driver, and the positioning control device and the resecting driver are both connected to the output end of the processor; the simulation training system comprises the steps of designing a manikin; arranging the imaging system; integrated resection. The resection device can resect the whole tumor along the edge of the tumor, thereby avoiding the incomplete resection and even tumor recurrent caused by crushing in the process of resecting the tumor. The simulation training system can train an operator to quickly master the resection skill and operation of various positions.

Abstract: A plasma cutting or welding system includes a power input. The power input is configured to be coupled to a plurality of multipronged input plugs. Each of the multipronged input plugs corresponds to an input voltage. The power supply also includes a user input device for selecting an operating current. The user input device is subdivided into a plurality of current ranges. Each of the current ranges includes an iconic representation of at least one multipronged input plug.

Abstract: A method of operating a computing device to explore content of a data storage, such as a binary file, using a format definition. The format definition comprises a class, with data members of the class representing a layout of data elements and their relationships in a type of a data storage. The relationships among the data elements may be represented using inheritance. The class derives from a base class providing reflection functionality. The reflection allows parsing the class so that its data members and their values are accessed at runtime, using the base class. Results of the parsing are presented in a form that allows exploring the content of the data storage and modifying the parsing results. New data may be created that conforms to the modified results.

Abstract: A method of operating a computing device to represent and explore content of a data storage, such as a binary file, using a format definition. The format definition comprises classes, with data members of one or more of the classes representing a layout data elements and their relationships in the data storage. The relationships among the data elements may be represented using inheritance. In the format definition, a class may derive from a base class providing reflection functionality. The reflection allows parsing instances of the class so that their data members and their values are accessed at runtime, using the base class. Results of the parsing are presented in a form that allows exploring the content of the data storage and modifying the parsing results. New data may be created that conforms to the modified results.
