摘要:
A high-durability printhead for an ink cartridge printing system. The printhead includes a substrate having ink ejectors (e.g. resistors) thereon and an orifice plate positioned above the substrate. The orifice plate (which preferably involves a non-metallic polymer film) has a top surface, bottom surface and a plurality of openings therethrough. To improve the durability of the orifice plate, a protective coating is applied to the top surface and/or the bottom surface of the plate. Representative coatings involve dielectric compositions (including diamond-like carbon) or at least one layer of metal. This approach improves the abrasion and deformation resistance of the plate and avoids "ruffling" and "dimpling" problems.

摘要:
A method and apparatus for encoding channel quality indicator (CQI) and precoding control information (PCI) bits are disclosed. Each of the input bits, such as CQI bits and/or PCI bits, has a particular significance. The input bits are encoded with a linear block coding. The input bits are provided with an unequal error protection based on the significance of each input bit. The input bits may be duplicated based on the significance of each input bit and equal protection coding may be performed. A generator matrix for the encoding may be generated by elementary operation of conventional basis sequences to provide more protection to a most significant bit (MSB).
摘要:
The number of users and data capacity of wireless systems are increased by employing apparatus and method for increasing the number of spreading codes available in the system by providing a mechanism to reuse the already allocated spreading code or use the codes that may correlate to those already being used within the same sector/cell. This, in return, provides capacity improvement proportional to the number of added base station (BS) antennas for each cell. An antenna null steering technique for code allocation maintains the cross correlation properties of the codes only for the desired user and to obtain a gain in capacity improvement.

An apparatus for improving transmission bandwidth is provided in the embodiments of the present disclosure, which includes: a signal transmission line, side grounds located at two sides of the signal transmission line, and a capacitor disposed between the signal transmission line and the side grounds. The signal transmission line comprises a microstrip line, and the signal transmission line and the side grounds form a coplanar waveguide transmission line together. On a transmission channel connected through a bonding wire, a capacitor is disposed between a signal transmission line and side grounds. An inductor-capacitor (LC) resonance circuit is formed by using inductance characteristics presented by the bonding wire and the capacitor connected in parallel with the bonding wire, and a resonance point is formed within a frequency band in a frequency domain.

An analog/digital gain control device avoid some of the requirements associated with the nature of a closed-loop AGC circuits and which meets the remaining requirements without much difficulty uses an analog to digital conversion method that increases the number of effective ADC bits by compressing the baseband input analog signal using a logarithmic circuit. After the compressed analog signal is converted into a digital signal, a digital anti-log process or look-up table (LUT) is used to expand the digital signal back to the original linear scale. The word size of the output of the anti-log process is larger than the input word size due to the nature of the anti-log function. To reduce the word size of the digital signal an open loop normalization technique can be applied.
摘要:
A wireless communication apparatus which uses fast Fourier transforms (FFTs) in an orthogonal frequency division multiplexing (OFDM) receiver which incorporates a beam space antenna array. The beam space antenna array may be implemented with a Butler matrix array. The beam space antenna array may be a circular array, vertical array, or a combination of both circular and vertical arrays, for providing the desired angular antenna coverage. In one embodiment, the antenna array is optimized because the FFTs are linear invariant transform operators, whereby the order of operations in the OFDM receiver can be interchanged.
