摘要:
A pneumatic radial tire has at least one carcass reinforcing ply and a pair of opposing bead portions. Each bead portion has a bead core and a bead apex, while the carcass reinforcing ply has a main portion and two turnups, with one turnup extending from each end of the main portion and having a terminal end. In each bead portion, there is a minimum distance DMIN between the carcass main portion and the carcass turnup, as measured perpendicular to the tire equatorial plane EP. The distance DMIN is not less than 50% of the maximum bead core width WB as measured perpendicular to the equatorial plane EP. In each bead portion, radially outward of the minimum distance DMIN, a radially outermost portion of the carcass turnup extends at an angle so the radially outermost portion of the carcass turnup is divergent from the carcass main portion.

摘要:
The present invention provides multiple test structures for performing reliability and qualification tests on MEMS switch devices. A Test structure for contact and gap characteristic measurements is employed having a serpentine layout simulates rows of upper and lower actuation electrodes. A cascaded switch chain test is used to monitor process defects with large sample sizes. A ring oscillator is used to measure switch speed and switch lifetime. A resistor ladder test structure is configured having each resistor in series with a switch to be tested, and having each switch-resistor pair electrically connected in parallel. Serial/parallel test structures are proposed with MEMS switches working in tandem with switches of established technology. A shift register is used to monitor the open and close state of the MEMS switches. Pull-in voltage, drop-out voltage, activation leakage current, and switch lifetime measurements are performed using the shift register.

Micro-electromechanical switches (MEMS) are configured to form a data storage latch to reduce power consumption, to reduce the space used in an integrated circuit, and to improve performance of the integrated circuit. MEMS are implemented at the wiring layer connected to an integrated circuit and coupled to form a storage latch.

A Dual Channel Mode for selecting specific waveform sets or characters in the applied data eliminates round trip delay errors in automatic test equipment. Drive waveforms and data are directed by a compiler to a first channel, while receive waveforms and data are directed to a second channel, eliminating false readings induced by the round-trip delays. The drive and compare waveforms are separated onto the first and second channels of electronics.

摘要:
Performing electronic voting by utilizing the ATM network and ATM machines; issuing voter cards to voters; modifying existing ATM software to recognize the voter card; maintaining a voter registration database; and making the voter registration database available to the ATM network. In use, the voter is matched to the database, and to voting options, and is restricted options specified by the database. A voting record, such as record, photo and verification, is stored in the database. A paper receipt is issued to the voter for verification.
摘要:
A method for forming a heat spreading apparatus for semiconductor devices is disclosed. The method includes extruding a frame material to form multiple individual cells including fillable openings within the frame material; filling a first group of the individual cells with one or more high thermal conductivity materials; filling at least a second group of the individual cells with one or more materials of lower thermal conductivity than in the first group of the individual cells; and implementing a reflowing process following filling the multiple individual cells so as to infiltrate the materials within the individual cells, wherein defined walls of the frame material remain following the reflowing.
