  • Publication number: 20200123484
    Abstract: An integrated chip is provided and comprises systems for sperm sorting, oocyte incubation and fertilization and liquid perfusion. The sperm sorting system comprises an inlet, an outlet, a main channel and a branch channel. The main channel has a width which increases along a direction from the inlet toward the outlet. The branch channel is connected to the main channel. The oocyte incubation and fertilization system is connected to the branch channel and comprises upper and lower holes. The upper hole is larger than the oocyte to hold the oocyte to be fertilized by a sperm. The lower hole is smaller than the oocyte. The sorted sperms are introduced into the oocyte incubation and fertilization system through the branch channel, to fertilize with the oocytes in the upper holes. The liquid perfusion system is located below the lower holes and a liquid exchange is performed through the second holes.

  • Patent number: 7357532
    Abstract: A lamp module mounted on a housing is provided. The lamp module includes a lamp and a lamp sleeve. The plane perpendicular to an optical of the lamp has an x-axis direction and a y-axis direction mutually perpendicular to each other. The lamp is mounted within the lamp sleeve, and a positioning piece is formed at one end of the lamp sleeve for mounting the lamp sleeve on the housing. The positioning piece at least includes a first surface and a second surface respectively parallel to the x-axis direction and the y-axis direction. At least one of the first surface and the second surface is equipped with an adjustable apparatus for adjusting the alignment of the lamp by moving the positioning piece along the direction(s) of the x-axis or/and the y-axis. The adjustable apparatus comprises a positioning component, a fastener and an elastic component.

  • Publication number: 20060262278
    Abstract: A projector includes a light module and an optical engine. The light module includes a fixture, at least a light source and a light guide element. The light source, disposed on the fixture, is for emitting a light along a direction. The light guide element, disposed on the fixture and adjacent to the light source, is for changing the direction of the light. The optical engine, disposed near the light module, is for receiving the light emitted from the light guide element and for generating an image. The fixture is detachably disposed on a projector, so that the light module is detachably disposed on the projector.

  • Publication number: 20060197924
    Abstract: A distance adjusting apparatus is disposed between a first optical module and a second optical module for adjusting the distance between the two optical modules and includes a supporting component, a stroke ring and an elastic component. The supporting component includes a bump. The stroke ring includes a spiral surface. Two ends of the elastic component are respectively connected to the first and the second optical modules. An elastic restoring force generated by the elastic component is applied onto the first and the second optical modules, so that the bump presses the spiral surface. By applying a force onto the stroke ring to rotate the spiral surface, a relative movement occurs between the bump and the spiral surface, so that a relative displacement of the stroke ring moving forward along an axial direction is controlled, and that the distance between the first and the second optical module is adjusted.
