    Abstract: The invention is based on the realization that feedback control for the vertical drive of a pin head becomes unnecessary if one instead prealigns the relative heights of the spotting surface and the well plates such that the pins in the pin head are lowered to the same absolute height both for picking up liquid from the well plates and depositing it onto the spotting surface. By aligning the heights of the well plates and spotting surfaces, the vertical drive of the pin head needs only to be able to reproducibly and accurately arrive at a single lowered position. A pin head can provide this functionality by having a mechanically defined bottom point, obviating the need for a complex and costly feedback control system for height determination of the pins. A simple, low-cost micro-arrayer can thus be provided.

    Abstract translation: 本发明基于这样一种认识，即如果一个针对喷头表面和井板的相对高度预先对准，使得销头中的销降低到相同的绝对高度，则针头的垂直驱动的反馈控制变得不必要 两者用于从井板拾取液体并将其沉积在点样表面上。 通过对准井板和点样表面的高度，针头的垂直驱动仅需要能够再现和准确地到达单个降低的位置。 针头可以通过具有机械限定的底点来提供该功能，从而避免需要用于销的高度确定的复杂且昂贵的反馈控制系统。 因此可以提供简单，低成本的微阵列器。

    Abstract: A low cost radio frequency interference filter assembly comprises a multiple layer structure including a middle trace layer disposed between an upper ground layer and lower ground layer. Non-conductive insulation layers are disposed between the middle trace layer and the upper and lower ground layers. The upper layer includes input contacts, signal contacts, and capacitors which are coupled to the signal contacts and an upper grounded substrate. The middle trace layer includes a grounded substrate and trace lines which are coupled to the signal contacts of the upper layer by signal vias. The lower layer includes a grounded substrate. Ground vias are formed through the insulation layers to couple the middle grounded substrate to the upper and lower grounded substrates. The filter assembly may be formed as an integral projection of a printed circuit board assembly. A structure for an RF power amplifier assembly is provided along with methods for manufacturing a filter assembly and assembling an electronics assembly.

    Abstract: For use with RF circuitry in which a DC bias circuit provides bias voltage is provided to impedance-matched circuitry, a structure is provided, in which a dielectric member, having a high dielectric constant, is selectively placed adjacent to a bias feed line coupled between the DC bias circuit and the remainder of the circuitry, to maintain high RF impedance while reducing impedance at lower frequencies. The invention has particular applicability to RF amplifiers, to be used for amplifying modulated carriers, such as video signals made up of an RF carrier and a lower-frequency modulation. Where the carrier has a predetermined wavelength, the physical length of the bias feed line and the dielectric constant of the dielectric member are chosen such that an effective length of the bias feed line is a quarter of the wavelength of the carrier.
