Abstract:
A light collection system including a light concentrating device and a reflective curving-surface device is provided. The light concentrating device receives at least a portion of an incident light and forwardly emits the portion of the incident light after concentrating and passing it through a first focal region, so as to obtain a first-stage output light. The reflective curving-surface device has an entrance aperture for receiving the first-stage output light. The reflective curving-surface device includes a reflective inner curving surface, and at least a portion of the reflective inner curving surface has a second focal region. The first focal region and the second focal region are confocal or approximately confocal within a range. As a result, at least a portion of the first-stage output light is confocally converted into a forwardly emitted second-stage output light.

A method of adjusting selected window size of an image object is applicable for tracking a target object in a video. The video includes a plurality of frames, and the target object has a display range changing with the playback of each frame. According to a variation trend of the display range of the target object, whether a variation times corresponding to the variation trend reaches a threshold value or not is recorded, and then the selected window size is reset, such that the target object is enclosed with a selected window having a size closer to the target object.

The method is characterized in that the property of the data is determined by its length, and the data is written to the high density memory unit or the low density memory unit according to the property of the data and the relative wearing rate and the amount of data processed by the storage device.
Abstract:
An image detection method is performed by a computer to determine whether or not an image in a region shot by a camera changes. According to the method, consecutive images shot by the camera are captured, and at least one anchored frame for the consecutive images is set. Whether or not the images in the anchored frame should or should not change is determined, and a signal is transmitted to determine whether or not the detected region is normal or not. Then, a notification signal is transmitted automatically to remind supervisors to closely observe the detected region.
Abstract:
A wafer thinning system and method are disclosed that includes grinding away substrate material from a backside of a semiconductor device. A current change is detected in a grinding device responsive to exposure of a first set of device structures through the substrate material, where the grinding is stopped in response to the detected current change. Polishing repairs the surface and continues to remove an additional amount of the substrate material. Exposure of one or more additional sets of device structures through the substrate material is monitored to determine the additional amount of substrate material to remove, where the additional sets of device structures are located in the semiconductor device at a known depth different than the first set.
Abstract:
A highly efficient data characteristic identification device for flash memory is provided, including an instruction register, a plurality of auxiliary controllers, a data register, an address register, a microprocessor, a plurality of hash function units, a hash table unit, a comparator, a shifter, and an adder. By connecting the instruction register, data register and address register to a flash memory access control circuit and flash memory for storing the control instruction of the access control circuit and the data and physical and logical address of the flash memory, the control instruction is decoded and transmitted by the microprocessor and the auxiliary controllers to each circuit. A plurality of hash function units, a hash table unit, a comparator, a shifter, and an adder form an index computation circuit for flash memory LBA. By using the index and computation on the contents of the hash function units, the data characteristics of the LBA can be stored with less memory and higher efficiency. Therefore, the object of a highly efficient data access characteristic identification device for flash memory is provided.
Abstract:
A wireless LAN medium access controller supporting mode change and the mode change method thereof are proposed. A physical layer detects signal strength in the environment and writes a mode index value of the stronger signal into a register. When the written mode index value is different from a mode index value in the communication system, a medium access controller is informed to perform mode change. The physical layer then sends out an interrupt signal to a central processor and sends the mode index value to the central processor for comparison via a DMA module and a memory. An interface module is used to access the mode index value in the memory for providing an external interface for the medium access control layer. When the mode index value doesn't conform to the signal in the environment, a software layer in the medium access controller is used for mode change.
