Abstract: The invention discloses a reticle pod including a base and a lid mounted to the base. The base has a bottom surface having at least one first mark and at least one second mark. The first mark has a first reflectivity relative to a light source, and the second mark has a second reflectivity relative to the light source. The first reflectivity is different from the second reflectivity, and both are also different from that of the rest area of the bottom surface.

Abstract: A mirror therapy device includes a support unit, a camera unit and a display unit. The support unit has a control area adapted for supporting a normal hand of a patient thereon, and an image area disposed adjacent to the control area. The camera unit is disposed above the support unit, and includes a lens confronting the control area and adapted for capturing an image of the normal hand, and a processor coupled electrically to the lens for receiving the image thus captured and generating a mirror image mirroring the captured image. The display unit is disposed on the image area and is connected electrically to the processor for receiving and displaying the mirror image.

Abstract: A motor coordination testing device includes a signal generator and a signal retrieving device. The signal generator includes a first electronic protractor, a second electronic protractor, a first support rotatably coupled with the first electronic protractor, and a second support rotatably coupled with the second electronic protractor. The signal retrieving device is electrically connected to the signal generator.

Abstract: A developer cup. The developer cup includes a bed. A central spindle is vertically and rotatably coupled to a center of the bed through an end of the central spindle. A chuck is vertically coupled to an end of the central spindle opposite to the bed end. An upper coupling is coupled to the central spindle between the chuck and the bed, wherein the chuck. A lower coupling is moveably coupled to the central spindle between the upper coupling and the bed. The annular cup has an upper wheel and a lower wheel, wherein the upper wheel is aligned with the lower wheel, the upper wheel is coupled to the lower wheel through a plurality of the brackets, and the lower wheel is smaller than the upper wheel.
