  • Patent number: 11434083
    Abstract: Disclosed herein are reclaimer systems, troughs, and methods for selectively positioning at least a portion of an upper portion of a trough relative to a vertical axis to adjust an operative height of the trough and thereby set an overflow threshold height for the reclaimed material, wherein reclaimed material below the overflow threshold height contributes to a target reclaim rate for the reclaimer system, and wherein the trough is configured to permit overflow of reclaimed material above the overflow threshold height.

  • Publication number: 20220212282
    Abstract: A system and method for making vias in a laminated printed circuit board (PCB). A drill having both a mechanical drill and a laser drill is used to make the via. The mechanical drill is moved over a location in the PCB where a blind via is desired. The mechanical drill drills to a point where a tip of a bit of the mechanical drill is a predetermined distance above a target interconnect layer. Then the drill is moved such that the laser drill is located over the via where the mechanical drill had drilled the via. The laser drill then ablates the resin remaining above the target interconnect layer.

  • Patent number: 6798843
    Abstract: A wideband predistortion system compensates for a nonlinear amplifier's frequency and time dependent distortion characteristics. The system comprises a data structure in which each element stores a set of compensation parameters (preferably including FIR filter coefficients) for predistorting the wideband input transmission signal. The parameter sets are preferably indexed within the data structure according to multiple signal characteristics, such as instantaneous amplitude and integrated signal envelope, each of which corresponds to a respective dimension of the data structure. To predistort the input transmission signal, an addressing circuit digitally generates a set of data structure indices from the input transmission signal, and the indexed set of compensation parameters is loaded into a compensation circuit which digitally predistorts the input transmission signal.

  • Patent number: 6697436
    Abstract: A predistortion system adaptively compensates for distortion introduced along one or more amplification chains of a power amplifier system. In one embodiment, the predistortion system includes a plurality of compensation circuits, each of which is coupled to, and configured to digitally predistort an input transmission signal to, a respective amplification chain of an antenna array system. Each such amplification chain has an output coupled to a respective antenna of the antenna array system. A processing unit monitors the input transmission signals to, and corresponding output signals from, each of the amplification chains on a time-shared basis, and generates updates to the compensation parameters used the corresponding compensation circuits.

  • Patent number: 6313703
    Abstract: A LINC amplifier of a radio frequency transmitter provides substantially linear amplification from two nonlinear amplifiers by decomposing the original signal into two constant amplitude envelope, phase varying signals, which, when combined, constructively and destructively interfere to re-form the original signal. The output of the LINC amplifier, which is to be transmitted via an antenna, is an amplified form of the original signal. The LINC amplifier uses a digital control mechanism to control and adapt a digital compensation network that directly compensates for the imperfections of the analog RF environment, including the amplifiers. The mechanism monitors the combined amplifier output and adjusts the signal components in order to precisely compensate for any differences in the characteristics of the separate signal paths which would cause the combination not to accurately represent the original signal.

  • Patent number: 6112055
    Abstract: A paging protocol includes header synchronization and system information segments containing information that allows a pager to conserve power. These segments can indicate a schedule of transmissions, and the channels of other transmissions. The pager can use this information to reduce the time the pager is in a high-power mode. In addition, the addresses are ordered so that the pager can more quickly determine whether a page is addressed to that particular pager. Further, the pager can activate circuitry in a sequenced manner to reduce peak power usage. The transmissions on different channels are synchronized in an offset manner so that the pager can scan one channel and switch to a next channel and immediately receive the start of a frame. Still further, the pager can be configured to perform narrowing searches during the initial acquisition process, which are then widened if no active channels are detected.
