20120058736 | Transceiver Front-End - A transceiver front-end provides an interface between a transmission medium and transmitter, and between a transmission medium and receiver. The transceiver front-end includes a hybrid circuit, a high-pass filter, and a gain stage, that permits the reduction or the complete elimination of buffer amplifiers. Buffer amplifiers can be eliminated because the hybrid circuit and/or the high-pass filter are adapted so that they can be directly connected to each other, without a loss in circuit performance. Furthermore, the high-pass filter and/or the gain stage are also adapted so they can be directly connected. As such, the transceiver front-end can be constructed using all passive components, reducing or eliminating excess heat generation. | 03-08-2012 |

20140177768 | Digital Calibration of Analog Distortion Using Split Analog Front-End - A receiver is disclosed that is capable of correcting for harmonic distortion injected into received analog signals. The receiver splits the analog signal in the analog front-end and modifies the split analog signals with a difference signal. After amplification and/or sampling, the modified analog signals are recombined in a main data pathway and are kept separate in a secondary pathway. Utilizing the difference signal, a feedback loop that includes distorters and an LMS filter detects the distortion coefficient of the harmonic distortion. A distorter in the main data pathway utilizes the detected distortion coefficient to correct the harmonic distortion in the analog signal. | 06-26-2014 |
20150085412 | OVERVOLTAGE PROTECTION CIRCUIT WITH DIGITAL CONTROL - A device for digitally protecting against an overvoltage event may include a front-end circuit, an overvoltage protection circuit, and a protection switch. The protection switch may be coupled to the overvoltage protection circuit and may be configured to decouple the front-end circuit from an external medium, in response to a clamp signal. The overvoltage protection circuit may be configured to detect the overvoltage event at one or more nodes of a circuit. In response to the detection of the overvoltage event, the overvoltage protection circuit may generate the clamp signal to activate the protection switch. | 03-26-2015 |

20150132535 | SANDWICH PANEL, METHOD OF BUILDING SUCH A SANDWICH PANEL, A CORE OF SUCH A SANDWICH PANEL, AND A BUILDING BUILT OF A PLURALITY OF SUCH SANDWICH PANELS - The invention relates to a sandwich panel, comprising: —a core, comprising: —a plurality of zigzag-shaped first spacers extending in a first longitudinal direction, each first spacer comprising at each corner thereof a first loop; —a plurality of zigzag-shaped second spacers extending in the first longitudinal direction, each second spacer comprising at each corner thereof a second loop, each second loop having outer dimensions that are smaller than the inner dimensions of each first loop, —wherein the second loops of each second spacer extend through the first loops of an adjacent first spacer; —wherein the openings defined by the second loops of successive second spacers are registered in rows extending in a second longitudinal direction, which second longitudinal direction extends under an angle of at least 20° with respect to the first longitudinal direction; and—wherein the first spacers and the second spacers define a second zigzag-shape in the second longitudinal direction; —two skin layers arranged on opposite sides of the core, wherein each skin layer comprises a plurality of openings through which the second loops extend; —a plurality of rods, each rod extending through the openings of the second loops of each row at the outer surface of each skin layer such that each rod locks the second loops in the first loops with respect to the skin layer. The invention further relates to a method of building such a sandwich panel, a core of such a sandwich panel, and a building built of a plurality of such sandwich panels. | 05-14-2015 |
