The Transfer Length Method or the "Transmission Line Model" (both abbreviated as TLM) is a technique used in semiconductor physics and engineering to determine the specific contact resistivity between a metal and a semiconductor.
2D TLM example: an incident voltage pulse in two consecutive scattering events. The TLM method is based on Huygens' model of wave propagation and scattering and the analogy between field propagation and transmission lines. Therefore, it considers the computational domain as a mesh of transmission lines, interconnected at nodes.
A direct-drive mechanism is a mechanism design where the force or torque from a prime mover is transmitted directly to the effector device (such as the drive wheels of a vehicle) without involving any intermediate couplings such as a gear train or a belt.
Catapult C supports SystemC model generation intended for virtual platforms, and a SystemC test environment to verify the generated RTL against the original C++ using the original C++ testbench. Catapult C supports the synthesis of Transaction Level Models (TLM), including standard off-the-shelf bus interfaces and custom protocols.
The stationary (stator) windings of an outrunner motor are excited by conventional DC brushless motor controllers. A direct current (switched on and off at high frequency for voltage modulation) is typically passed through three or more non-adjacent windings together, and the group so energized is alternated electronically based upon rotor position feedback.

The L3A is the direct-injection 1.5 L naturally-aspirated variant of the SGE used in the second-generation Chevrolet Volt, with a 74 mm × 86.6 mm (2.91 in × 3.41 in) bore and stroke for a total capacity of 1,490 cc (1.5 L). The compression ratio is 12.5:1 and the engine can run on regular unleaded-grade gasoline.
The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors , power is delivered to windings in the stator (case) rather than the rotor . This simplifies mechanical design because power does not have to be delivered to the moving rotor, which eliminates the need for a commutator .
