Abstract: A detection system and method for the migrating cell is provided. The system is configured to detect a migrating cell combined with an immunomagnetic bead. The system includes a platform, a microchannel, a magnetic field source, a coherent light source and an optical sensing module. The microchannel is configured to allow the migrating cell to flow in it along a flow direction. The magnetic field source is configured to provide magnetic force to the migrating cell combined with the immunomagnetic bead. The magnetic force includes at least one magnetic force component and the magnetic force component is opposite to the flow direction of the microchannel. The coherent light source is configured to provide the microchannel with the coherent light. The optical sensing module is configured to receive the interference light caused by the coherent light being reflected by the sample inside the microchannel.

Abstract: A 3D printer system that uses the AM method to print a product using a plurality of materials, each of which is contained in a respective capsule. The capsules are removably inserted into respective capsule holders, each of which includes a heating device for adjusting the temperature of the material, and is releasably held in one of a plurality of stations. A tool fetches individual capsules from and deposits them to their stations, and holds individual capsules for printing the product using a telescopic extrusion apparatus. A memory stores capsule-identifying data, a processor provides position coordinates for positioning of the tool, and a controller moves the tool to the position coordinates. The capsule holders include heating systems for controlling the rheological behavior of the materials based on algorithms executed by the processor.

Abstract: A belt adjusting device of a printer includes a bracket, a base, a driving device, and a resisting member. The bracket includes a bottom wall and a belt placed on the bottom wall. The belt is loop-shaped. The base is slidably mounted to the bracket. The driving device is mounted to the base and includes an eccentric device engaging with the belt. The resisting member resists the driving device to enable the eccentric device to rotate to adjust the belt when the base slides relative to the bracket.

Abstract: A printer includes a hanger, a printer head, a carriage, and an adjustment assembly. The hanger includes a base and a board above the base. The carriage includes a body, a rod, and an actuator. The body is rotatably connected to the rod. The actuator is rotatably connected to the body. The actuator includes a projection and a resisting member. The adjustment assembly includes a protruding post. When the body moves in a first direction, the projection applies a push force to the protruding post, the protruding post rotates downward. When the body moves in a reverse, second direction, the protruding post applies a push force to the projection, which causes the actuator to rotate, the lateral surface of the resisting member stays in contact with the board during the rotation of the actuator, causing the carriage to rotate, the distance between the printer head and the base is changed.
