Title: Diffuser for direct type backlight unit
Inventor: LEE HYUN-SU
IPC: G02B5/02
Filed: 2006-12-19
Abstract: A dot pattern is formed either on a surface of a diffuser 35 or of a diffusion sheet 37 facing lamps 33. The dot pattern serves to disperse light at the centre of the lamps 33 and to condense light in a boundary between them. The diffuser 35 may be part of a direct backlight unit for an LCD display that comprises a reflecting plate 31 and a prism sheet 39, and can use either fluorescent tubes or LEDs as a light source. The dot pattern may comprise a main pattern (fig 4, I) at the centre of a lamp that lowers transmissivity and a sub dot pattern (fig 4, II) of relatively smaller size that enhances transmissivity. The dots may be circular or diamond-shaped and are formed by printing using a transparent ink mixed with a reflective white ink. The diffuser 35 reduces the mura or variation in luminance of the backlight.

Title: An internal combustion engine with in-cylinder pressure measurement system
Inventor: KENCHINGTON STEVEN
IPC: F02D35/02
Filed: 2007-01-22
Abstract: With reference to Figure 1, the present invention provides an internal combustion engine comprising a cylinder (12); a piston (11) reciprocating in the cylinder (12) and defining with the cylinder (12) a combustion chamber (10). An inlet poppet valve (14) controls admission of air into the combustion chamber (10). An exhaust poppet valve (16) controls exhaust of combusted gases from the combustion chamber (10). A first position sensor (40) measures deflection of the inlet poppet valve (14) when the valve is closed and deflects under pressure applied by gases in the combustion chamber (10). A second position sensor (41) measures deflection of the exhaust poppet valve (16) when the valve (16) is closed and deflects under pressure applied by gases in the combustion chamber (10). An electronic engine management system (31) aggregates / averages deflection signals from the first (40) and second (41) position sensors and from the aggregated signals determines a value for in-cylinder pressure.

Title: Encryption system for peer-to-peer networks in which data is divided into chunks and self-encryption is applied
Inventor: IRVINE DAVID
IPC: H04L9/00
Filed: 2007-05-22
Abstract: A file is divided into chunks 2 and small data elements, such as bytes, are permuted between the chunks 3. Each chunk is hashed 4 to form a chunk hash, and each chunk hash is encrypted using one or more other chunk hashes 5 in a self-encryption process. Self-encryption involves obfuscation using algorithms seeded by elements preferably derived from the data itself so that the data holds the key to reversing the processes. The chunk hashes and the encrypted chunk hashes are constituents of a mapping function. The chunks are distributed across various nodes of a peer-to-peer network. The permutation of the chunks contributes towards the effective encryption of the file. The file can be recovered using the mapping function. Also disclosed is "duplicate removal" and "storing files".

Title: Process of preparation of biodegradable films from semi refined kappa carrageenan
Inventor: GHOSH PUSHPITO KUMAR
IPC: B29D7/01
Filed: 2007-05-24
Abstract: The present invention relates to use of inexpensive semi-refined kappa carrageenan as a seaweed polysaccharide in preparation of tough, biodegradable films exhibiting improved performance over films obtained from refined kappa carrageenan. The formulation requires no gelling salt and the only other essential components of the film are glycerol and water, the former being used as plasticizer as reported in the prior art. The films can be recycled and reprocessed if required. The performance of the films can be further enhanced by incorporating polyvinyl alcohol that lends toughness and clarity as also natural rubber latex that imparts greater elasticity and barrier properties. Films of optimum composition can be pulse heat sealed immediately after casting and used for preparation of soft capsules and pouches. It is possible to store solvents and oils in the pouches. In view of the more eco-friendly processing of semi-refined kappa carrageenan compared to refined kappa carrageenan, films made with the former would also effectively be "greener".

Title: Vehicle bonnet hinge with pedestrian safety feature
Inventor: CHEAL JONATHAN PAUL ANTHONY
IPC: B60R21/34
Filed: 2007-09-01
Abstract: A hinge assembly 10 (110, figure 3), for connecting a bonnet to a body of a vehicle and allowing a rear portion of the bonnet to be raised in the event of a collision, comprises first 12(112), second 14(114), third 16(116) and fourth 18(118) links and a locking mechanism 20(120). The first link is pivotally connected to the second link. The third link is pivotally connected between the second and fourth links. The locking mechanism is engageable with, and releasable from, a lockable link, which is one of the second and fourth links, so as to prevent and allow, respectively, relative movement between the second and fourth links. The third link is pivotally connected to one of the second and fourth links by a moveable pivot 29(129), which allows the third link to be rotated relative to the second and fourth links. The third link or the pivot is engageable with the locking mechanism such that when the locking mechanism is engaged with the lockable link, rotation of the third link 16 relative to the second and fourth links releases the locking mechanism from the lockable link. A telescopic 22(122) actuator linked to a supply of compressed gas may operate to urge the third link from first to second positions.

Title: Picture adaptive frame or field (PAFF) coding for MPEG2 using temporal displacement and distortion thresholds
Inventor: AMMU SATYAGHOSH
IPC: H04N7/26
Filed: 2007-11-01
Abstract: A video picture encoder and method arranged to use a field mode or a frame mode to encode a video picture 10. The encoder comprises: means for determining a ratio of a frame activity to a field activity of the picture; selection means arranged to select the field mode if the ratio is less than or equal to a predetermined lower threshold value and to select a frame mode if the ratio is equal to or greater than a predetermined upper threshold value. Computation means are arranged to compute a temporal displacement and a temporal distortion of the picture if the ratio falls outside the range of lower threshold value to higher threshold value. In that case, the field mode is selected if the temporal displacement is greater than a predetermined temporal displacement threshold or the temporal distortion is greater than a temporal distortion threshold but otherwise the frame mode is selected.

Title: A circuit for securing against non-reset of a device in power-up reset procedures
Inventor: DEWAR KEVIN
IPC: G06F21/75
Filed: 2007-12-14
Abstract: A security circuit comprises first and second registers 3, 5 producing respective first and second multi-bit output values; inverter 9 for inverting one of the output values; comparator 7 comparing the non-inverted and inverted output values and producing a comparator output; and wherein registers 3, 5 are subject to substantially similar operating conditions (e.g. the registers are located in close proximity). In a normal reset procedure (26), expected bit values are compared with a user input and the comparator output indicates that the circuit is in a known state (e.g. a secure mode). If an attack is made (e.g. tampering) registers 3, 5 will power up in an undefined state and each bit of the registers tends to settle towards a particular logical state. Because of the self similarity of register cells it is highly probable that the non-inverted and inverted output values are different, leading to a self reset (27) in a known state. Once in a known state, user authentication procedures (28) occur.

Title: A chemFET with PPi receptor
Inventor: ROTHBERG JONATHAN M
IPC: G01N27/414
Filed: 2008-06-25
Abstract: Methods and apparatus relating to very large scale FET arrays for analyte measurements use a chemFET with a PPi receptor. ChemFET (e.g., ISFET or ENFET) arrays using receptors may be fabricated using conventional CMOS processing techniques based on improved FET pixel and array designs that increase measurement sensitivity and accuracy, and at the same time facilitate significantly small pixel sizes and dense arrays. Improved array control techniques provide for rapid data acquisition from large and dense arrays. Such arrays may be employed to detect a presence and/or concentration changes of various analyte types in a wide variety of chemical and/or biological processes. In one example, chemFET arrays facilitate DNA sequencing techniques based on monitoring changes in the concentration of inorganic pyrophosphate (PPi), hydrogen ions, and nucleotide triphosphates.
