摘要： Methods and apparatus are disclosed to implement programmable logic generators that provide the advantages of compatible look-up tables (LUTs) while utilizing less silicon real estate and power for the same number of functions. The disclosed methods and apparatus employ programmable switches to emulate memory units that are used in LUTs and illustrate construction of 2- and 3-input LUTs as building blocks of other multi-input LUTs.

摘要： An installer is installed in a hole in a ceiling or a wall and includes a speaker frame and two connective units. The speaker frame may fix down a speaker and has a circumferential edge. The two connective units are provided on the speaker frame and either connective unit has a connective flexible strip, which may contract or expand laterally by moving in the longitudinal direction. First, as the two connective flexible strips contract inwardly in the radial direction, the speaker may be allowed to pass and then be placed in the hole. Then, as the two connective flexible strips expand outwardly in the radial direction, the diameter formed by the two connective units is larger than that of the hole. Now, the outer layer of a wall or a ceiling is sandwiched in between the circumferential edge and the two connective flexible strips.

摘要： Methods and apparatus for decreasing oxide stress and increasing reliability of memory transistors are disclosed. Duration and frequency of exposure of memory transistor gates to read signals are significantly reduced. In some embodiments, after a short read cycle, the content of the memory cell is latched and maintained as long as the subsequent read attempts are directed to the same memory cell. In these embodiments the read cycle need only be long enough to latch the memory content of the cell, and as long as the subsequent read attempts target the same memory cell the latched value will be used instead of repeating the read process.

摘要： Memory cells comprising an SRAM and an OTP memory unit are disclosed that combine the advantages of both technologies and can be fabricated by standard CMOS manufacturing without additional masking. Disclosed concepts and details may be applied to and utilized in other systems requiring memory and/or employing other fabrication technologies. Among other advantages, the SRAM part of disclosed memory cells allows countless programming of the cell, which is useful, for example, during the prototyping. The OTP part is utilized to permanently program the memory cell by either using external data or the data already existing in the SRAM part of the cell. The value held by the OTP unit may also be written directly into the SRAM part of the cell.

摘要： A high stability loudspeaker has a yoke with a plurality of vents installed therein. The yoke is combined to a bottom of a frame of the loudspeaker. A magnet is placed in the yoke. A washer is arranged above the magnet. A periphery of the magnet is surrounded by a voice coil. A coil winding surrounds the voice coil. A combining portion is formed at a periphery of the yoke. The combining portion serves to be combined with a surround connected to a bottom of end of the voice coil. The voice coils is vertically installed in a gap between the portions of the yoke. The top of the voice coil is connected to another surround. Thereby, vibration of the voice coil is confined at the two ends. As a result, the gap between portions of the yoke structure into which the voice coil extends between portions of the yoke is reduced and therefore, the sensitivity of the loudspeaker is increased and the distortion is decreased.
