91results about How to "Reduce granularity" patented technology

Integrated multi-touch surface having varying sensor granularity

This relates to an event sensing device that includes an event sensing panel and is able to dynamically change the granularity of the panel according to present needs. Thus, the granularity of the panel can differ at different times of operation. Furthermore, the granularity of specific areas of the panel can also be dynamically changed, so that different areas feature different granularities at a given time. This also relates to panels that feature different inherent granularities in different portions thereof. These panels can be designed, for example, by placing more stimulus and / or data lines in different portions of the panel, thus ensuring different densities of pixels in the different portions. Optionally, these embodiments can also include the dynamic granularity changing features noted above.

LDPC concatenation rules for 802.11n systems

Improved LDPC code structure and concatenation rules for IEEE 802.11n systems, providing two code sets per rate, one longer codeword and one shorter codeword. The longer codeword length is determined by the system parameters, while the shorter codeword length is ⅓ of the longer codeword length. A LDPC concatenation rule is provided, wherein a maximum of one extra OFDM symbol is added in padding in order to reduce the code set granularity. In order to provide improved code performance, more bits are shortened compared with puncturing, by transmitting the extra OFDM symbol. Further, all the required puncturing and shortening bits are distributed across all codewords. This scheme provides a preferred tradeoff between code complexity and over-the-air efficiency.

A Fabry-Perot interference sensor based on solid-core photonic crystal fiber and its manufacturing method

The invention provides a Fabry-Perot interferometric sensor based on a photonic crystal fiber and a manufacturing method thereof. The sensor is composed of a conventional communication single-mode fiber and a solid photonic crystal fiber, wherein the conventional communication single-mode fiber and the solid photonic crystal fiber are welded by using a certain welding method. Because air holes ona cladding of the photonic crystal fiber collapse, an air cavity (namely, an F-P cavity) is formed between the two fibers, and the two end faces (namely, the front and rear surfaces of the air cavity) of the photonic crystal fiber and the single-mode fiber are two reflecting surfaces of the F-P cavity. The solid photonic crystal fiber is made of a single material, and does not cause the mismatching of thermal expansion coefficients of materials in the process of temperature variation, thereby ensuring that the influence of temperature variation on the interferometric sensor is small; in the manufacturing process, only a fiber cutting and welding process is used, therefore, the preparation process is simple; by using the sensor, high-fineness and high-contrast interference fringes can be obtained, therefore, the sensor has a great application potential in large-capacity and quasi-distributed sensing systems; and the sensor is in an all-fiber structure, and has the advantages of small volume, good robustness and low cost.

Data packet length indication for mobile telecommunications systems

In a data packet, e.g. a PDU of the UMTS, a length indicator field of variable granularity is created, depending on the exact length of the payload to be transmitted. An additional field is provided, a single bit in length, to indicate the granularity of the length indicator field. This increases the resolution of the header, whilst keeping low an overhead of extra field bits. The method comprises: assessing the length of the data to determine the appropriate units, from a plurality of possible units, in which the length should be expressed; setting the granularity field to define the appropriate units in which the length of the data is to be indicated; and setting the length indicator field to indicate the data length.

Display device

A display device for a vehicle includes a display LCD and a control LCD, which has transmission switching portions, each of which has three segment units. When the vehicle is running, left-side two-third segment units of each transmission switching portion are set to a non-transparent state in a portion of the control LCD corresponding to the left half screen of the display LCD. In contrast, in a portion of the control LCD corresponding to the right half screen of the display LCD, all the segment units are set to a transparent state. Thus, an image in the right half screen is visible from a driver seat, while an image in the left half screen is not visible from the driver seat. Both the images in the right half screen and the left half screen are visible from a front passenger seat.

The present invention provides methods and an infrastructure for performing repetitive data protection and a corresponding restore of data for block oriented data objects comprising several indexed segments. For implementing the invention, timestamps tk are set by a timer k. Only the first data modification of a segment is recorded, after a timestamp tk has been set, by storing the old data contents of said segment together with the segment index j and said timestamp tk as undo-log block in a first journal j0, before overwriting said segment with the modified new data. Besides, said undo-log blocks are transmitted to N journals ji for storing redundant undo-log information, with N>1 and i=0, . . . , N−1.
