Techniques and mechanisms for enabling small radius bending of a flexible circuit. In an embodiment, the flexible circuit includes a first section, a second section and a third section between the first section and second section. Stacked structures of the first section include a first trace portion and a first conductor, and stacked structures of the second section include a second trace portion and a second conductor. In another embodiment, a first span structure of the third section exchanges a first signal between the first trace portion and the second trace portion while the first conductor and the second conductor are maintained at a reference potential. While the first signal is exchanged, a second span structure of the third section—coplanar with the first span structure—is maintained at the reference potential or propagates a second signal complementary to the first signal.

Three-dimensional (3-D) volumetric board architectural design provides technical solutions to technical problems facing miniaturization of circuit boards. The 3-D volumetric architecture includes using more of the unused volume in the vertical dimension (e.g., Z-dimension) to increase the utilization of the total circuit board volume. The 3-D volumetric architecture is realized by mounting components on a first PCB and on a second PCB, and inverting and suspending the second PCB above the first PCB. The use of 3-D volumetric board architectural design further enables formation of a shielded FEMIE, providing shielding and improved volumetric use with little or no reduction in system performance or increase in system Z-height.

The present invention specifically permits purging and/or sampling of a well but only removing, at most, about 25% of the fluid volume compared to conventional methods and, at a minimum, removing none of the fluid volume from the well.The invention is an isolation assembly that is inserted into the well. The isolation assembly is designed so that only a volume of fluid between the outside diameter of the isolation assembly and the inside diameter of the well over a fluid column height from the bottom of the well to the top of the active portion (lower annulus) is removed. A seal may be positioned above the active portion thereby sealing the well and preventing any mixing or contamination of inlet fluid with fluid above the packer. Purged well fluid is stored in a riser above the packer. Ports in the wall of the isolation assembly permit purging and sampling of the lower annulus along the height of the active portion.

Techniques for encoding data are described herein. An example of a device in accordance with the present techniques includes a signaling module coupled to a plurality of digital inputs. The signaling module is to encode data received at the plurality of digital inputs to generate encoded data. Based on the encoded data, the signaling module can drive line voltages on a plurality of signal lines of a bus. Each one of the plurality of line voltages corresponds to a weighted sum of the data received at the plurality of digital inputs.

A low weight encoding circuit of a power delivery system for encoding data sent out on an I/O bus with minimal current drawn so as to minimize signal and timing distortions. Such a low weight encoding circuit comprises a current balance tester arranged to test whether a predetermined number of data bits is current balanced; a current balance encoder and decode bit generator arranged to encode data bits and generate encoded data and corresponding decode bits if the predetermined number of data bits is not current balanced; and a latch arranged to latch either the data bits, via an I/O bus, if said predetermined number of data bits is current balanced or the encoded data and corresponding decode bits, via the I/O bus, if the predetermined number of data bits is not current balanced.

An apparatus includes a substrate, a ground plane on the substrate, the ground plane having a slot, transmission lines lying over the slot, and data processing agents each connected to one of the transmission lines. A method includes inducing a transient return current on a reference plane in response to a driving agent sourcing a current being representative of binary data onto a first transmission line, the current being representative of binary data, propagating energy of the transient return current to a slot in the reference plane, inducing a transient voltage pulse onto a second transmission line connected to a receiving agent when the propagating energy encounters the second transmission line and generating a binary digital signal in the receiving agent from the transient voltage pulse received on the second transmission line.
