Abstract: Optimization design method for configurable analog circuits and devices resulting from same. An implementation fabric for a given application domain can be accurately pre-characterized in terms of devices and parasitics. Customization structures are designed and characterized to be applied to the fabric to customize a device for a particular application. In some embodiments, characterization is accomplished by formulating a configurable design problem as an optimization with recourse problem, for example, a geometric programming with recourse (GPR) problem. Devices can be produced for multiple applications from the application domain using the same optimized fabric to provide predictable performance.

Abstract: An actuator device for setting a downhole tool is disclosed. The actuator device includes a gas releasing material that releases a gas when activated by a solvent or other activator. The gas produced due to the contact with the activator is captured within a chamber in the downhole tool. As a result, gas pressure builds up inside the tool to move a piston and cause setting of the downhole tool.

Abstract: A trigger device for setting a downhole tool is disclosed. The trigger device includes a retaining member that prevents the downhole tool from setting until it is properly positioned within the well. Regardless of the type of downhole tool or the type of trigger device, the retaining member includes a dissolvable material that dissolves when contacted by a solvent. The dissolvable material is preferably one that dissolves at a known rate so that the amount of time necessary for the downhole tool to set is pre-determined. Preferably, the solvent is a water-based or hydrocarbon-based drilling fluid or mud.

Abstract: A gas chromatograph with multiple valves is disclosed. An embodiment of the multi-valve gas chromatograph includes multiple valves, multiple thermal conductivity detectors (TCD's), and a manifold. This allows separation and measurement of a gas sample in one compact integrated unit. The unit is particularly desirable because the solenoids associated with the valves are attached directly to the underneath of the manifold, thus eliminating the need for tubing between the solenoids and the valves. Other features may also be present. For example, a leak free multi-valve block may include a first temperature zone heating the valves and detectors and a second temperature zone heating the columns. The leak free feature may be achieved by placement of tightening screws through the center of each valve. Carrier gas insertion areas may be provided in the multi-valve block to improve performance. Improved separation of the temperature zones leading to further gains in performance can be achieved by use of both a thermal insulator and an air gap. Further, the temperature sensors placed in the first temperature zone can be ideally located to minimize measurement error, resulting in yet further performance gains.

Abstract: An object of the present disclosure is to provide a beamforming method for a massive MIMO system. Specifically, S routes of data streams to be transmitted via the antenna array are subjected to horizontal direction baseband beamforming processing, to obtain T routes of data streams; the T-routes of data streams are subjected to vertical direction digital beamforming processing to map the T routes of data streams onto a corresponding channel according to a predetermined rule; a data stream on each channel is subjected to analog beamforming processing to map the data stream on each channel onto a corresponding array element of the antenna array for transmission. Compared with the prior art, the present disclosure implements the following advantages: by combining the advantages of RF beamforming with the BB beamforming with limited antennas at the FH, a good flexibility regarding BB algorithm selection and RF beam design is provided, which balances the complexity and performance between BB and RF and implements a massive MIMO in sub-6 GHz.
