Title: Non real-time delivery of MPEG-2 programs via an MPEG-2 transport stream
Inventor: ELSTERMANN ERIK JOHN
IPC: H04N7/52
Filed: 2000-12-08
Granted: 2002-09-01
Abstract: Digital content is extracted from single and multiple-program transport streams for subsequent non-real-time (background) transmission in a bandwidth-efficient manner. The content of the transport streams may include anything from targeted commercial advertisements to broadcast full-length movies. At an encoder (100), several null and/or nonessential (N/N) packets (e.g., packets of unused programs) in a transport stream are replaced by an annotation packet (AP) to obtain non-real-time packets (410). The non-real time packets are inserted into null packet locations (NU) of a real time transport stream. At a decoder (200), the annotation packets are used to regenerate a specified number of null packets to maintain the original separation of packets of the non-real time data (for timing purposes), allowing existing hardware and/or software to decode the selected program. Optionally, the non-real-time packets provide pre-encrypted programs, and decryption information is distributed to the decoders at a formal program release time specified by the program provider.

Title: Servo motor drive control system
Inventor: SANO SYUYA
IPC: H02P5/54
Filed: 2001-01-17
Granted: 2006-09-21
Abstract: A servo motor drive control system comprising a command unit, e.g. a numeric controller, a plurality of drive controllers for controlling the drive of a servo motor, a first communication line for transmitting data, e.g. a control command, from the command unit to the drive controllers, and a second communication line for transmitting data, e.g. detection data, from the drive controllers to the command unit and adapted for controlling the servo motor synchronously by communicating data among the drive controllers through the communication lines, wherein the cycle of communication among the drive controllers is 1/n (n is an integer) that of the command unit. Since an synchronism error correction control command can be transmitted at high speed from one drive controller to another drive controller without being restricted by the control cycle of the command unit, no operation load for generating a synchronism error correction control command is imposed to the command unit, and the synchronism error due to a disturbance, e.g. an impulse, can be converged in a short time.

Title: Image display apparatus, method for repairing chipping of image display apparatus, method for attaching repairing material of dot chipping, and method for applying repairing material of dot chipping
Inventor: IWABUCHI SHIROYUKI
IPC: G02F1/1335
Filed: 2001-05-10
Granted: 2002-10-21
Abstract: An image display apparatus (1), such as a liquid crystal display apparatus, wherein a plurality of display elements are arranged, uses an optical transfer material (7) continuously covering the surfaces of at least two display elements (2) to compensate for a dot chipping occurring in one display element (2') by transferring a display of an adjacent display element (2) to the display element (2') having the dot chipping. The optical transfer material comprises, for example, a photochromic material. Thus, even when a dot chipping occurs in a liquid crystal display apparatus, the display of a normal display element (2) is caused to be displayed in a display element (2') having the dot chipping, thereby repairing that display element having the dot chipping. In this way, the product yield can be improved, and the cost can be reduced.

Title: Enhanced fuses by the local degradation of the fuse link
Inventor: KOTHANDARAMAN CHANDRASEKHARAN
IPC: H01L23/525
Filed: 2001-08-01
Granted: 2003-01-21
Abstract: Described herein is a fuse incorporating a covering layer disposed on a conductive layer, which is disposed on a polysilicon layer. The covering layer preferably comprises a relatively inert material, such as a nitride etchant barrier. The covering layer preferably has a region of relatively less-inert filler material. Upon programming of the fuse, the conductive layer, which can be a silicide, preferentially degrades in the region underlying the filler material of the covering layer. This preferential degradation results in a predictable ""blowing"" of the fuse in the fuse region underlying the filler material. Since the ""blow"" area is predictable, damage to adjacent structures can be minimized or eliminated.

Title: Ink cartridge gas refilling device
Inventor: SHIU CHI-JUNG
IPC: B41J2/175
Filed: 2001-07-27
Granted: 2002-10-11
Abstract: The present invention proposes an ink cartridge gas refilling device which is not interfered or affected by the magnetic field. According to the present invention, a venting hole can be installed to be vented to the atmosphere, and the venting hole is connected to a fixing seat. The fixing seat has a venting hole connected to the ink cartridge, the exterior of the venting hole of the fixing seat is covered with a gas-sealing material with expandable elastivity. The circumference of the venting hole is sealed with the air-sealing material so that the ink cartridge is sealed in the normal state. When the ink level of the ink cartridge is graduated reduced by consumption in the operating of jet printing, the external air cannot get in since the sealing material seals the venting hole, the volume of air becomes larger due to the lowering of the ink level, from Boyle's and Charles' law, the phenomenon can occur: when the mass and temperature of gas is constant, if the volume is larger, the pressure will reduce. Therefore, when the print head continues to consume the ink, the negative pressure in the cartridge will continue to increase. When the difference between the internal pressure and the external pressure of the ink cartridge reaches a critical value, it will be pushed slightly by the external atmosphere pressure, minute amount of air will flow into the cartridge automatically, so that the negative pressure in the cartridge will return to an operable range. At this time, since the difference between the internal pressure and the external pressure of the ink cartridge reduces, and the expanding elastivity of the sealing material is larger than the atmosphere pressure, therefore the venting hole is sealed again, the ink cartridge is continuously kept in the negative pressure state.

Each target address has cached with it in the BTAC an associated offset within the instruction cache line of the previously executed associated branch instruction as well as a valid bit and a prediction of whether the branch instruction will be taken or not taken. Control logic selects the first, valid, taken, and seen target address. The target address is ""seen"" if the associated offset is greater than or equal to a corresponding portion of the least significant bits of the fetch address.
