Locally implemented terminal latency mitigation
Terminal latency mitigation improves performance of networked consoles by embedding latency mitigation functionality in a terminal emulator. An enhanced terminal reduces perceived and actual delays by accurately predicting responses a remote service will provide to key press data. Latency mitigation may receive key press data, transmit it toward the remote service, locate a prediction, obtain a prediction string from the prediction, and write the prediction string to a display. A prediction indication may visually indicate the presence of a prediction string as opposed to an actual response from the remote service.

When the prediction is accurate the terminal shows the prediction string without the prediction indication. When the prediction is inaccurate, the terminal replaces the prediction string by the response. The enhanced terminal may be server kernel independent, shell independent, and independent of proprietary communication protocols. |

Electro-active lenses with raised resistive bridges
Resistive bridges can connect many ring electrodes in an electro-active lens with a relatively small number of buss lines. These resistors are usually large to prevent excessive current consumption. Conventionally, they are disposed in the same plane as the ring electrodes, which means that the ring electrodes are spaced farther apart or made discontinuous to accommodate the resistors. But spacing the ring electrodes farther apart or making them discontinuous degrades the lens's optical quality. Placing the ring electrodes and resistors on layers separated by an insulator makes it possible for the ring electrodes to be closer together and continuous with resistance high enough to limit current consumption. It also relaxes constraints on feature sizes and placement during the process used to make the lens. And because the resistors and electrodes are on different planes, they can be formed of materials with different resistivities. |

Dual engine-compressor system
The present invention is directed to a dual engine-compressor system having a crankcase enclosing a crankshaft and having engine cylinder housings and compressor cylinder housings linearly disposed on opposite sides of the crankcase. Combustion pistons are reciprocatingly disposed in the engine cylinder housings and defines alternating combustion chambers on opposite sides of the pistons. Compressor pistons are reciprocatingly disposed in the compressor housings and define alternating low and high pressure compressor chambers on opposite sides of the compressor pistons. The compressor pistons undergo a 4-cycle process to drawn in, re-distribute, and then compress fluid. The compressor cylinder and piston has a series of one-way intakes and reed valves to selectively draw or push fluid in response to movement of the compressor piston. |

Assembly for producing a thermostatic element
This assembly comprises a cup containing a thermally-expandable material, a piston designed to move in translation along an axis (X-X) under the action of the thermally-expandable material, a guide (40) for guiding the piston and intended to be fixed to the cup, and a buffer (60) made of an elastomer material and designed to be interposed between the thermally-expandable material and the piston. The guide is provided with a bore (41) that is intended to be centered on the axis and comprises a first bore portion (41.2) having a constant cross-section, a second bore portion (41.1) provided to receive the piston and having a cross-section that is both constant and smaller than that of the first bore portion, and a third bore portion (41.3) that continuously connects the first and second bore portions. According to the invention, the buffer consists of both first and second end portions (62, 61), which, in the assembled state of the thermostatic element, are respectively received in the first and second bore portions regardless of the translational position of the piston, and of a running portion (63), which coaxially connects the first and second end portions and which, before assembly of the buffer to the rest of the thermostatic element, is at least locally thinner relative to the first end portion, so that, in the assembled state of the thermostatic element, the running portion passes from one to the other of the first and second boring portions, via the third boring portion, and partially releases the internal deformation stresses of the buffer when the piston is translated. |

Wind turbine having a reduced radar cross section
A wind turbine including a support structure and one or more turbine blades is presented, that incorporates ways for reducing the radar cross section (RCS), wherein the support structure is notionally divided into an upper section in the shadow of the blade sweep area, and a lower section beneath the upper section, wherein the upper section is adapted to have the ways for reducing the RCS, and the lower section does not have the adaptation. The invention makes use of the realisation that the blade masking the tower as it rotates (or the blade being masked by the tower if facing away from a radar), contributes significantly to interference to radar systems, and so localised application of e.g. RAM can give good RCS reduction at a lower cost than treating the whole structure. |
