Abstract: The present invention is a thermal and acoustic insulating sphere that has an evacuated hollow interior. The spheres are constructed of insulating materials, and the inner and outer surfaces of each sphere have highly reflective coatings evenly applied to them. The coatings applied to the inner and outer surfaces reduce the transmission of heat by conduction, convection, and radiation. Additionally, the spheres provide superior acoustic insulation due to the inability of sound to travel through the interior vacuum. The spheres can be used to produce insulating materials, for example, by embedding or positioning them within or between other materials, to provide thermal and acoustic insulation.

Abstract: Heat and Sound Insulation Ball (HASIB) is a hollow ball which has vacuum inside and is made of insulating materials like fiber-reinforced-plastic and glass. The inner and the outer surfaces of HASIB have non-conducting highly reflective coatings. HASIB is a much better heat insulator and its use can reduce the transmission of heat by conduction, convection and radiation. The use of HASIB for heat insulation can save energy and bring down the cost of heating in winter and cooling in summer. HASIB is also a better sound insulator since sound cannot travel through the vacuum inside it. HASIB can be used in the form of HASIB-wrap which can be made by gluing them between two sheets of plastic. HASIBs can also be embedded in the drywall used for the construction of houses to make the drywall a much better heat and sound insulator.

Abstract: Example methods are disclosed for encoding variable sized data using a low-density parity-check (LDPC) code, and transporting the encoded variable sized data in modulated symbols. Example methods involve calculating a minimum number of modulated symbols capable of transmitting a data packet; selecting a codeword size suitable for transmitting the data packet; calculating a number of shortening Nshortened bits; and calculating a number of puncturing Npunctured bits, to thereby produce a shortened and punctured expanded parity check matrix for transmitting the data packet.

Abstract: An EEPROM memory transistor having a floating gate. The floating gate is formed using a BiCMOS process and has a first sinker dopant region proximate to a tunnel diode window, and a second sinker dopant region proximate to a coupling capacitor region. An optional third sinker region may be formed proximate to a source junction of the EEPROM memory transistor. Also, a shallow trench isolation (STI) region may be formed between the first and second sinker dopant regions.

Abstract: An EEPROM memory cell uses silicon-germanium/silicon and emitter polysilicon film for fabricating shallow source/drain regions to increase a breakdown voltage with respect to a well. The source/drain regions are fabricated to be approximately 100 nm (0.1 micrometers (?m)) in depth with a breakdown voltage of approximately 14 volts or more. A typical breakdown voltage of a well in a bipolar process is approximately 10 volts. Due to the increased breakdown voltage achieved, EEPROM memory cells can be produced along with bipolar devices on a single integrated circuit chip and fabricated on a common semiconductor fabrication line.
