Title: Optimized synchronization preamble structure
Inventor: DOLLE THOMAS
IPC: H04L7/10
Filed: 2000-05-26
Granted: 2003-11-01
Abstract: This proposal describes an optimized synchronization (SYNCH) symbol sequence to be used in transmission systems, which are currently under standardization. The synchronization symbol is constructed using specially designed OFDM (orthogonal frequency division multiplexing) symbols with an optimized sequence, which is mapped onto the modulated subcarriers. The resulting synchronization symbol consists of several repetitions in the time domain. Using the proposed sequence the resulting synchronization symbol achieves a high timing detection and frequency offset estimation accuracy. Furthermore the burst is optimized to achieve a very low envelope fluctuation (low peak-to-average power ratio) and a very low dynamic range to reduce complexity on the receiver and to save time and frequency acquisition time in the receiver. The proposed sequence is furthermore optimized with respect to all other synchronization symbols that are used to construct the synchronization and training preambles for the BCCH-DLCHs.

Title: Joint pile
Inventor: MIURA FUSANORI
IPC: E02D5/22
Filed: 2000-10-04
Granted: 2002-01-01
Abstract: A joint pile interconnects an upper pile and a lower pile, which will move relative to each other when the position of the crust of the earth changes. The upper and lower piles are interconnected easily using a simple structure. This can increase both the deformation energy of the connecting portion of the joint pile and the destruction-preventing effect of the joint pile. The connecting portion of the joint pile includes an upper end plate 3 disposed at an lower end portion of the upper pile 1, a lower end plate 4 disposed at an upper end portion of the lower pile 2, a resilient body 5 disposed between the upper end plate 3 and the lower end plate 4, and a movement limiting member, such as a ring-shaped shear band 6 for limiting relative lateral movement between the upper end plate 3 and the lower end plate 4. Because the connecting portion of the joint pile has a large deformation energy, upon change of the crust of the earth, it can deform, and can thus be prevented from destruction. Shear-resistant connecting portion can also be prevented from outward offset to the left and the right.

Title: Gray level conversion method and display device
Inventor: TOBIYA AKIRA
IPC: H04N5/202
Filed: 2001-06-04
Granted: 2005-02-11
Abstract: In order to correct the gray level of a liquid crystal display (100), based upon a control signal (21) from a computer (2) for setting an LUT in the liquid crystal display (100), a signal source (3) generates a group of analog RGB signals (11) having values corresponding to various gradients, and gives these to an analog/digital converter (4). Moreover, a luminance meter (1) measures a gray level, for example, the luminance (14), displayed by a liquid crystal display panel (6). Data (15) corresponding to the luminance (14) measured by the luminance meter (1) is given to a computer (2). The computer (2) compares values of the group of RGB signals (11) outputted by the signal source (3) and the value of the data (15), and stores the resulting conversion characteristic (16) in an LUT memory means (5). The application of a rewritable memory, such as a RAM and an EEPROM, as the LUT memory means (5) makes it possible to cancel individual differences in the display characteristic of the display panel, and consequently to obtain a desired gray level. Thus, the relationship between the input signal and the gray level so as to have a desired characteristic is obtained.

Title: Compact, high collection efficiency scintillator for secondary electron detection
Inventor: WANG LI
IPC: H01J37/244
Filed: 2001-09-14
Granted: 2002-07-11
Abstract: A scintillator assembly used in a FIB (focused ion beam) system to detect secondary electrons achieves nearly 100 percent collection efficiency for the majority of useful secondary electron energy ranges. Further, the insulator in the assembly is placed such that it is completely out of the secondary electron path in order to avoid arcing which affects FIB secondary electron imaging. Also, the gap between the grounding cap and the scintillator allows high collection efficiency offered by earlier designs to be retained, and at the same time, improves the system reliability. Further, the scintillator assembly may be placed closer to the primary ion beam, which further improves collection efficiency.

Title: Auto-calibration circuit to minimize input offset voltage in an integrated circuit analog input device
Inventor: DARMAWASKITA HARTONO
IPC: H03M1/12
Filed: 2001-09-28
Granted: 2002-12-01
Abstract: An auto-calibration circuit minimizes input offset voltage in an integrated circuit analog input device. The auto-calibration circuit may also calibrate a plurality of analog input devices on an integrated circuit die or in a multi-chip package (MCP). The auto-calibration circuit and analog input device(s) may be fabricated in combination with a microcontroller system on an integrated circuit die or in an MCP. The auto-calibration circuit controls input offset voltage compensation circuit that counteracts or compensates for input offset voltage so as to minimize voltage error at the output of the analog input device. A digital control circuit applies a digital word to the input offset voltage compensation circuit for generating the required input offset voltage compensation. A linear search or binary search of various values of the digital word may be used by the digital control circuit. The digital control circuit switches the inputs, the output and feedback-gain determining resistors for the analog input device during a calibration mode. A voltage comparator compares the output of the analog input device and a voltage reference. When the output of the analog input device is equal to or greater than the voltage reference, the comparator output signals the digital control circuit by changing its output logic level. The input offset voltage compensation circuit of the analog input device has a storage register or memory that retains the digital word which compensates for the input offset voltage.
