Compressed nitrogen entrains working fluid in a multiphase riser, reducing lift energy while driving a turbine generator.

A subsea cable assembly amplifies flotation travel and converts linear wave motion for hydraulic conversion across a full wave period.

An offset inner piston becomes flush with the main piston near top dead center, controlling detonation timing and reducing component stress.

A force-modifying mechanism and compliant link increase SMA actuator force and stroke while reducing actuator size and power consumption.

An inserted rigid sleeve limits flexible pipe deformation, stabilizing airflow and improving MAF sensor accuracy.

This case uses passive wing drag and mechanical linkages to retract a vertical turbine into a pole-like form.

This case enlarges outer-blade soundproofing means when site turbulence is lower, improving induction and reducing wind-turbine noise.

This case adapts rotor blade soundproofing to site turbulence, increasing induction factor while maintaining noise reduction.

Pressurized air pockets drive inertial liquid pumping for wave energy conversion.

The controller tracks fuel injection and sub-tank levels, limiting engine torque before fuel depletion disrupts jet-pump supply.

Quaternary-carbon metal alkanoates reduce lubricant wear, friction, foaming, and SAPS.

A reinforced bracket guides the injector onto the cylinder head, reducing assembly distortion, pressure loss, vibration, and noise.

This case combines separate excitation and filtering paths to adapt level measurement to medium conductivity and dielectric properties.

This case uses wave-induced tilting and trapped water levels to generate power with fewer maintenance-prone moving parts.

Air-driven oil droplets are collected in a cylinder groove and redirected to lubrication points. This limits oil combustion and emissions.

A chromium-silicon steel piston blank resists scaling-related cracking, enabling higher combustion chamber temperatures.

PWM energization and pause-phase resistance measurements detect SMA actuator position through two wires, limiting heating and cable outlay.

Local cuts form chamfered ply edges, reducing ply drop effects while enabling thicker plies and fewer lay-up steps.

A contrasting inner layer helps image-capturing devices align 3D scans and assess blade-shell erosion under varying lighting.

Selective bonding between spar caps, lightning conductors, and an added conductor controls voltage differences in long blades.

Channel combining and measurement averaging improve weak-reflection detection at lower radar costs.

A segmented valve body and cap enlarge the sodium cavity while shielding the weld from combustion heat and fatigue.

A rocker compresses fluid from passing loads for steadier roadway energy harvesting.

A two-section sleeve accommodates injector misalignment, reducing seal forces and gaps that could admit dust into the engine.

This camera case uses upgoing and downgoing SMA drivers to balance lens forces, simplify wiring, and reduce autofocus stroke.

Carbon spar cap conductivity replaces mid-span conductors, reducing blade manufacturing complexity while preserving lightning protection.

Light-guide manifolds, shared telecentric optics, and SiPM detection improve lidar mapping precision and redundancy.

This case shows how a structural fan shroud replaces extra supports, stabilizing heat exchangers and enabling center-of-mass mounting.

A cylindrical seal bonded to the probe coating supports reliable fill level measurement while avoiding complex conical-seal assembly.

A guide-directed retractor uses linear blade movement along muscle fibers to limit muscular trauma and nerve compression.

A two-wire capacitive probe and instability-tuned oscillator help microcontrollers measure fluid levels with inexpensive components.

This bistable SMA actuator uses transient heating and elastic springs to hold microvalve positions without continuous external force.

This valve places a turbine in the downstream pressure recovery zone to recover kinetic energy and maintain flow and pressure.
