A drive system thermal temperature rise test and compensation system. The system has an optical non-contact type sensing head mounted on a main shaft of a machine tool, and a sensing center is formed in the center of the sensing head. A platform driven by a transmission device of the machine tool is provided with plural ball lens devices, and a temperature sensor for transmitting temperature data externally is further provided on the transmission device. After the machine tool sequentially records an original point coordinate for each ball lens center by using the sensing head, the sensing head is cyclically and sequentially moved to the original point coordinate of each ball lens, so as to measure a displacement error between the sensing center and the ball lens center resulted from thermal shifts of the transmission device, as well as capable of measuring multiaxial errors and using various axial temperatures for compensation.

A signal control module integrated to a low coherence interferometry including a one-dimensional (1D) array image sensor is provided. The signal control module includes an image acquisition controller and a signal controller. The image acquisition controller sends a 1D image acquisition control signal. The signal controller sends a two-dimensional (2D) image acquisition control signal, wherein the 1D and 2D image acquisition control signals are synchronized with each other. The 1D array image sensor captures 1D image information of an object-to-be-tested at different positions along a direction according to the 1D and 2D image acquisition control signals. The 1D image information constitutes 2D image information. Furthermore, a low coherence interferometry is provided.

An optical detecting apparatus for detecting a degree of freedom error of a spindle and has a standard bar and a sensor module, and is assembled between a spindle and a rotating platform of a powered machinery. The standard bar has a rod lens and a reflection face. The sensor module has two detecting groups, an oblique laser head, and a reflected spot displacement sensor. Each detecting group emits a laser light through the rod lens along the X-axis and the Y-axis of the powered machinery. The oblique laser head emits an oblique laser light to the reflected spot displacement sensor. When the spindle of the powered machinery generates errors after rotating, the sensor module receives the changes of the laser lights to obtain the displacement change signals of the standard bar for a calculation unit to detect the errors between the spindle and the rotating platform.

A heat dissipation device and a heat dissipation method are provided. The device is disposed in a case having a first opening and a fan for generating a first cooling air flow. The device includes a heat dissipation element and an air-guiding plate. The heat dissipation element has a first region and a second region, and the first cooling air flow flows from the first region towards the second region. The air-guiding plate is disposed in the first region of the heat dissipation element and used for reducing a cross-sectional area of the first cooling air flow flowing in the first region along a flow direction of the first cooling air flow, so as to draw air outside the case into the second region via the first opening to generate a second cooling air flow, thereby lowering a temperature of the case located below the heat dissipation element.

In a method for enabling a power-saving mode for an electronic apparatus, a power mode index Ips is determined according to transmission indices Bit&#x2dc;Bitn and/or port situation indices Ip&#x2dc;Ipm. For example, when the transmission indices Bit&#x2dc;Bitn are all under inactive states or when all the port situation indices Ip&#x2dc;Ipm are under disable states, the power mode index Ips indicates a highly power-saving mode D. When less transmission indices are under inactive states or when less port situation indices Ip&#x2dc;Ipm are under port disable states, the power mode index Ips indicates a primary or intermediate power-saving mode Dor D. The power mode index Ips can also indicate no power-saving mode Dwhen all transmission indices and/or port situation indices are active/enabled or the electronic apparatus is forced to remain normal power.

The present invention provides a high-speed, memory efficient parallel coding technique for embedded block coding with optimized truncation (EBCOT) used in still image compression. Attributing to parallel processing method and structure, it processes a discrete wavelet transform (DWT) coefficient at a clock cycle without any state variable stored. Therefore, the need of state variable memory can be avoid and the external memory bandwidth can be reduced. With the same cost of chip-area and lower power consumption, the processing rate of this invention is several times higher than conventional schemes. Furthermore, the present invention processes 50 M coefficients per second at 100 MHz and can encode lossless HDTV 720 p resolution pictures at 30 fps in real time.

A method for performing a load flow test among a number of IEEE 1394 controllers is provided. The IEEE 1394 controllers are disposed on a number of interface cards individually while the interface cards are placed in a host or several hosts. The method includes the following steps: The interface cards are first initialized. Then, the master interface card starts to perform the load flow test. After that, the status of every interface cards is checked for confirming whether an error occurs or not. If the error occurs, debugging is performed. If not, the slave interface cards checks the result of the load flow test. The invention can fully control the buffer and monitor the memory since the test method is not performed under the driver structure in the WINDOWS operating system. It is therefore convenient to test in a load flow environment by using this method.
