摘要:
A 3D shape-measuring apparatus using biaxial anamorphic magnification comprises a light source that projects a light onto an object surface to be sensed. Via an electrical image-grabbing device, such as CCD camera, the light reflected from the object is grabbed to determine the coordinate locations sensed on the object. Before the electrical image-grabbing device, the light reflected from the object passes respectively through a curved reflecting mirror or an assembly of telecentric cylindrical lenses to adjust an image magnification along the light projection direction, and an assembly of cylindrical lenses to adjust an image magnification along a direction perpendicular to the light projection direction. Thereby, resolution nonuniformity with respect to near and far distance is resolved while the observable range of the CCD camera can further be efficiently changed into a measurable field.

An image-measuring apparatus without axial alignment is configured to measure a workpiece. The image-measuring apparatus without axial alignment includes a rotating plate, a lighting unit, an image capturing unit, a central control unit and a rotary driving member. The workpiece is disposed on the rotating plate. The lighting unit is configured to generate a light beam to illuminate the workpiece to form a first workpiece blocking shadow area on the image capturing unit. The rotating plate and the workpiece are rotated through a rotational angle by the central control unit to form a second workpiece blocking shadow area on the image capturing unit. The central control unit calculates the first workpiece blocking shadow area and the second workpiece blocking shadow area to generate an axial position of the workpiece. There is a distance between an axial position of the rotating plate and the axial position of the workpiece.

A non-volatile memory access method and system, and a non-volatile memory controller are provided for accessing a plurality of physical blocks in a non-volatile memory chip, and each physical block has a plurality of physical pages. The method includes determining whether there is enough space in a first physical block to write a plurality of specific physical pages when data stored in one of the specific physical pages are to be updated; and writing valid data and data to be updated into the first physical block when the first physical block has enough space to write the specific physical pages.

A current-limiting protection circuit of remotely controlled ceiling fan-lamp is disclosed. The current-limiting protection circuit includes a microcontroller unit for detecting rectangular wave signal reflective of the power used by a lamp load. The rectangular wave signal is compared with nominal value. In the case that the positive bandwidth of the rectangular wave signal is larger than the nominal value, it is indicated that the lamp load is in an overloaded state. Under such circumstance, the microcontroller unit controls a lamp load driving unit to change driving manner and lower the power used by the lamp load to a value within the nominal range.
