Manipulation of playback device response using signal processing
Example techniques involve balancing bass response of a multiple driver playback device. An example playback device receives left and right channels of audio content and generates a center channel of the audio content by combining at least a portion of the left right channels. The playback device generates first and second side channels of the audio content by combining the center channel and a difference of the left channel and the right channel and combining the center channel and an inverse of the difference of the left channel and the right channel, respectively. The first and second side channels are attenuated by a filter with a given cutoff frequency. The center channel is amplified in proportion to the attenuation of the first side channel. The playback device plays back the first side channel, second side channel, and center channel according to respective radiation patterns having maximums aligned in respective directions. |

Distribution of prefixes in a network
Client device prefixes are distributed to other network devices (e.g., routers) in the network inside a special container attribute of an update message. The container attribute is attached as an optional-transitive attribute to a location prefix announcement. A location prefix identifies the Autonomous System (AS) that originates the client prefixes. All of the ID prefixes packed in the container use the location prefix as the recursive next-hop towards them. As a result, all convergence in the network occurs for a small number of location prefixes, while at the same time, the location/ID mapping is being distributed using the Location best-paths. In some embodiments, the container attribute can utilize BGP update packets, or optimized NLRI/attribute packaging. Compression of the ID prefixes can also be used within the messages. |

Oversampled continuous-time pipeline ADC with digital signal reconstruction
Continuous-time pipeline analog-to-digital converters can achieve excellent performance, and avoid sampling-related artifacts traditionally associated with discrete-time pipeline ADCs. However, the continuous-time circuitry in the ADCs can pose a challenge for digital signal reconstruction, since the transfer characteristics of the continuous-time circuitry are not as well characterized or as simple as their discrete-time counterparts.

Connector for electrical power cables
A connector (1) for two electrical energy cables is indicated. The connector (1) has a plug (2) and a socket (3) which each is able to be tightly connected and suitable to produce a releasable electrical contact between the conductors. The socket (3) has hollow space (12) running in the longitudinal direction and the plug (2) a protruding bolt (11) in the longitudinal direction which is pluggable in the hollow space (12). The hollow space (12) and the bolt (11) have the identical truncated conical shape to each other, so that the bolt (11) is fixable in the hollow space (12) in the operative position. The connector (1) has further a pin (15, 18) so arranged that its axis is right angled to a connector axis (10) of the connector (1) and interacts with a circumferential recess (17, 18) around the diameter of the bolt (11). |

Electrical contact terminal and electronic component socket
Contact pins are provided to a socket main body for accommodating an IC package so as to be in contact with connection terminals of the IC package accommodated in the socket main body. Each contact pin includes a conductive substrate and multiple layers laminated on the surface of the substrate, including: an underlying layer formed on the substrate by Ni plating; a first surface layer formed on the underlying layer by Pd—Ni alloy plating; a second surface layer formed on the first surface layer by Ni plating, thus allowing Sn from the corresponding connection terminal to diffuse into the second surface layer at a rate lower than into a conventional plated Ag layer; and an outermost surface layer formed on the second surface layer by Au plating to serve as an electrical contact layer. |

Connector
Housing includes: insertion part into which a connection target is inserted; a plurality of first grooves provided inside insertion part so as to align along an alignment direction being perpendicular to the insertion direction of the connection target, first contact parts being respectively disposed in first grooves; a plurality of second grooves provided inside insertion part so as to oppose to first grooves, second contact parts being respectively disposed in second grooves; first partition wall partitioning adjacent first contact parts; and second partition wall partitioning adjacent second contact parts. At least one of first partition wall and second partition wall has a height dimension in a direction perpendicular to both the insertion direction and the alignment direction, the height dimension being smaller at least at one end in the alignment direction than at a portion between opposite ends in the alignment direction in order to reduce capacitance between contact parts. |

CPU socket contact for improving bandwidth throughput
High-speed data transmissions through a CPU socket are facilitated with CPU socket contacts that have a CPU socket contact body that improves bandwidth throughput. The CPU socket contact body is partially suspended from a CPU socket contact and may include a cavity. The CPU socket contact body includes capacitive impedance that substantially cancels an inductive impedance of the CPU socket contact. Canceling the inductive impedance causes the CPU socket contact to operate like an impedance-matched coaxial transmission line, which enables better bandwidth throughput than a non-impedance matched transmission line. |
