Abstract: Hand-held analytical devices are provided for blood sugar tests. The devices can incorporate a replaceable test tape cassette having a test tape with a plurality of analytical aids and have a tape drive having a DC motor and gearing that can be coupled to the test tape cassette for successive provision of the analytical aids. The devices also include a control device for rotational speed control of the DC motor. Methods also are provided for operating such hand-held analytical devices.

Abstract: An image capturing apparatus and an auto-focusing method thereof are provided. The method includes transmitting light beams from light sources to an eye including a cornea, a pupil, a crystalline lens, and a fundus. The light beams are transmitted to the fundus through the cornea. The light beams transmitted to the cornea form first light point images detected by an image sensor through a lens module having first and second lenses. According to the first light point images and focal adjustment data, the first lens and the light sources are moved simultaneously to focus on the cornea. The light beams are substantially intersected at the pupil and transmitted to the fundus to form second light point images detected by the image sensor through the lens module. According to the second light point images and the focal adjustment data, the first lens is moved to focus on the fundus.

Abstract: An image detecting apparatus for detecting a first eyeball is provided. The image detecting apparatus includes an illumination light source, an imaging lens, an image sensing device, a display and a viewfinder. The illumination light source emits an illumination beam, and the illumination beam irradiates the first eyeball. The first eyeball reflects the illumination beam into an image beam. The imaging lens is disposed on a transmission path of the image beam. The image sensing device is disposed on the transmission path of the image beam, wherein the imaging lens is disposed between the first eyeball and the image sensing device. The display shows the image formed by the image beam. The viewfinder is disposed in front of the display such that a second eyeball observes the display via the viewfinder. An image detecting method is also provided.

Abstract: A method for moving a sledge disposed thereon an optical pickup head of an optical disc drive is provided for controlling the motion of the sledge relative to an optical disc loaded. The optical disc drive further includes a sledge motor. At first, the sledge motor drives the sledge to move toward the center of the optical disc. At the same time, the tracks crossed by the optical pickup head are detected and counted according to a tracking error signal generated by the optical pickup head. When the count or an increment in the count within a specific period is not larger than a predetermined value or the tracking error signal is undetectable, the optical disc drive immediately stops the sledge motor from driving the sledge. The monitoring mechanism can avoid undesired impact and noises of the sledge.
