Abstract:
A method and an apparatus for synchronization of a first set of mail with a second set of mail at the message/folder level (20). A memory (310) stores a mail synchronizer (340) for application independent e-mail message or folder in the mail boxes to be synchronized. An event log (344) is then generated for each mail box. The memory also has a synchronization mechanism (300) for making the first set of data and the second set of data equivalent by using the information in a Change List. A processor (316) runs the mail synchronizer (340).
Abstract:
A computer system (100) which includes a multimedia input device (121-129) which generates an audio or video input signal and a processor (109) coupled to the multimedia input device (121-129). The system further includes a storage device (107) coupled to the processor (109) and having stored therein a signal processing routine for multiplying and accumulating input values representative of the audio or video input signal. The signal processing routine, when executed by the processor, causes the processor (109) to perform several steps. These steps include performing a packed multiply-add on a first set of values packed into a first source and a second set of values packed into a second source, each representing input signals to generate a packed intermediate result.
Abstract:
A longitudinal electromagnetic emission sealer is constituted with an elongated elastomer core and a thin helical skin wrapped around the core. The elongated elastomer core is made of a flexible material that allows the core to be compressed in volume when pressure is exerted on the sealer. The helical skin is made of a material that can absorb electromagnetic emissions, even at minimal thickness, allowing the skin to wrap around the core in a helical manner easily. Additionally, a grove complementary in size to the sealer is provided to one side of the bracket of each card module for securing in place the sealer between the brackets of two card modules.
Abstract:
A ball grid array integrated circuit package (10) which has a plurality of vias (30) located within the solder pads (20) of a package substrate. The substrate supports an integrated circuit (24) which is connected to the solder pads (20) by the vias (30). Solder balls (36) used to solder the package (10) to an external printed circuit board (12) are attached to the solder pads (20) of the substrate. A solder mask plug (38) is formed within the vias (30) to prevent the solder balls (36) from wicking into the vias (30). Locating the vias (30) within the solder pads (20) optimizes the routing space of the substrate and increases the routing density of the package (10).
Abstract:
A method for removing Ball Limiting Metallurgy (BLM) layers (14, 15) from the surface of a wafer (10) in the presence of Pb/Sn solder bumps (17). In one embodiment, the BLM comprises two layers: titanium (14) and copper (15). After Pb/Sn solder-bumps (17) have been formed over the electrical contact pads (12) of the wafer (10), the BLM copper layer (15) is etched with a H2SO4+H2O2+H2O solution. While removing the copper layer (15), the H2SO4+H2O2+H2O etchant also reacts with the Pb/Sn solder bumps (17) to form a thin PbO protective layer (18) over the surface of the bumps (17). When the copper layer (15) has been etched away, the titanium layer (14) is etched with a CH3COOH+NH4F+H2O solution. The PbO layer (18) formed over the surface of the Pb/Sn solder bumps (17) remains insoluble when exposed to the CH3COOH+NH4F+H2O etchant, thereby preventing the solder bumps (17) from being etched in the presence of the CH3COOH+NH4F+H2O etchant. When the titanium etch is complete, the PbO layer (18) is removed from the surface of the Pb/Sn solder bumps (17) by exposing the bumps (17) to an HCl+NH2CSNH2+NH4Cl+H2O solution.
Abstract translation:一种在Pb / Sn焊锡凸块(17)的存在下从晶片(10)的表面去除球限制冶金(BLM)层(14,15)的方法。 在一个实施例中,BLM包括两层:钛(14)和铜(15)。 在晶片(10)的电接触焊盘(12)上形成Pb / Sn焊料凸起(17)之后,用H 2 SO 4 + H 2 O 2 + H 2 O溶液蚀刻BLM铜层(15)。 在去除铜层(15)时,H2SO4 + H2O2 + H2O蚀刻剂也与Pb / Sn焊料凸点(17)反应,在凸块(17)的表面上形成薄的PbO保护层(18)。 当蚀刻铜层(15)时,用CH 3 COOH + NH 4 F + H 2 O溶液蚀刻钛层(14)。 当暴露于CH3COOH + NH4F + H2O蚀刻剂时,形成在Pb / Sn焊料凸块(17)表面上的PbO层(18)保持不溶,从而防止在CH3COOH存在下蚀刻焊料凸点(17) + NH4F + H2O蚀刻剂。 当钛蚀刻完成时,通过将凸块(17)暴露于HCl + NH 2 CSNH 2 + NH 4 Cl + H 2 O溶液,从Pb / Sn焊料凸块(17)的表面去除PbO层(18)。
Abstract:
A system that displays text and graphic information with broadcasted television images includes a VBI inserter (16) for inserting data into the VBI of a publicly broadcasted video signal. An associated personal computer (10) includes a VBI decoder for separating the data from the video signal. The separated data contains command and address information which instruct the PC to retrieve text/graphic information from a storage device, and display the information on a monitor (30). The broadcaster inserts data that retrieves text and graphic information which correspond to the television image displayed by the monitor. The retrieved text and graphic data may be stored for later viewing by the user.
Abstract:
A dual-in-line Universal Serial Bus connector (345) including a plurality of Universal Serial Bus ports (400, 405) oriented adjacent to each other in a longitudinal direction. The dual-in-line Universal Serial Bus connector further includes a plurality of signal pins (435), coupled to the plurality of Universal Serial Bus ports (400, 405), which are configured to receive data input into at least one of the plurality of Universal Serial Bus ports (400, 405) and a pair of mounting tabs (430a, 430b). The positioning of the mounting tabs (430a, 430b) and signal pins (435) enable this connector to be used as a substitute for one of the serial COM port connectors (350) normally used by the computer system.

The opening is then oxidized a second time.
Abstract:
A method and apparatus for regulating the deferral of a transaction issued on a bus by a processor in a computer system is disclosed. A bus transaction recorder coupled to the bus processes encoded signals from the transaction issued on the bus. A line coupled to the bus sends an indication signal when a pending transaction request is issued on the bus. A CPU latency timer times the current transaction on the bus when a new pending transaction is waiting on the bus. The CPU latency timer outputs an expiration signal when the transaction takes more than a predetermined amount of time to complete. A transaction processor unit is coupled to the bus transaction recorder, the line, and the CPU latency timer. The transaction processor unit defers the transactions issued on the bus when the transaction processor receives the indication signal indicating that a pending transaction is waiting to be issued on the bus, when the encoded signals from the transaction issued on the bus indicate that the transaction issued on the bus is a candidate for deferral, and when the CPU latency timer outputs the expiration signal.
