Methods and systems are provided for cooling hot spots on a body coil assembly of an MRI system. In one embodiment, an airflow guide of a body coil assembly of an MRI system comprises a first surface that forms an air passage when the airflow guide is positioned on the body coil assembly, the air passage enclosed by the first surface and a second, outer surface of an RF coil of the body coil assembly, the airflow guide configured to channel cool air generated by a fan to the second, outer surface of the RF coil. The airflow guide may be arranged circumferentially around a portion of the RF coil at one or more ends of the RF coil. The airflow guide may be manufactured as a plurality of airflow guide segments that are glued together.

The present disclosure relates to an intelligent prevention passage control system for an electronic device, which comprises a detection device for an electronic device, a traffic control device integrated with the detection device for the electronic device, an industrial control host, a server, an access controller and a management terminal inside the traffic control device. The present disclosure can more accurately judge violations by scoring violations, and can make the system more intelligent by accurately judging violations, thus realizing no manual attendance, solving the problems of personnel recruitment, shift attendance and personnel management, and saving a lot of labor cost. At the same time, the system can avoid the hidden dangers caused by human feelings, sense of responsibility and inertia brought by manual prevention, and ensure the consistent, accurate and reliable standards of detection work.

Intelligent prevention passage control system for electronic device

Provided is a primer middle sequence interference PCR method, and the method uses one segment of a non-complemented or same-sequence base of the middle sequence of primers to perform antisense interference inside and outside the primer molecules, so as to competitively destroy the polymerization among the primers to selectively inhibit amplification of the primer dimer (PD).

A smart home system having a controller which controls an ozone generator, gas supply outlets connected to gas supply outlets of the ozone generator via a pipe, and solenoid valves which control opening and closing of the gas supply outlets. The controller is connected with each of the solenoid valves and controls opening and closing of each of the solenoid valves. An operation method for the system discloses driving the ozone generator by the controller to generate ozone, controlling opening of the solenoid valves by the central processor when the central processor receives an external signal for opening the solenoid valves, reducing opening level of the solenoid valves when a gas flow sensor detects that the ozone flow rate passing through the gas inlet is greater than the flow rate threshold, and controlling closing of the solenoid valves by the central processor when the central processor receives a signal for closing the solenoid valves.

Smart home system and operation method thereof

This disclosure relates to a gear pair for power transmission in a speed increaser or reducer and its tooth profile forming method. The tooth profiles of driving gear and driven gear are separately designed from reference points. The upper tooth profiles are composed of conjugate curves, while the lower tooth profiles are composed of smooth convex analytic curves. The reference point of the driven gear is located adjacent the middle of the working depth. The reference point on the tooth profile of the driving gear and the reference point on the driven gear tooth flank are a pair of conjugate points.

A differential features larger amplitude in gear ratio fluctuation and higher torque bias ratio. When one of the driving wheel slips, the period of the gear ratio fluctuation between the pinion and side gears involves at least two pitches, thus each period of the gear ratio fluctuation involves a group of teeth, and the number of teeth involved in each group are corresponding to the number of pitches involved in each period. Each pinion has an odd number of groups of teeth, and the group number in side gears is a multiple of the number of pinions. The differential is particularly suitable for off-road vehicles, tippers and wheeled civil engineering machinery.
