Electronic Solutions Ulm
The products include the LokPilot and LokSound series of decoders and recently the Märklin company has teamed up with ESU for the manufacture of the decoders for their new generation of mfx locomotive decoders. ESU is also an OEM supplier of decoders for a number of manufacturers.
ESU was one of the first manufacturers to produce decoders capable of sound - a feature that has become very popular with model railroaders. Their Loksound v3 decoders have the added benefit that end-users can re-program the sound files used by the decoder, using a LokProgrammer.
Some of their decoders such as the LokPilot and LokSound are multiprotocol in that they support the Motorola format as well as Digital Command Control (DCC) and also Märklin style analog AC current. Their LokPilotDCC on the other hand is a pure DCC decoder and will not work in a pure Märklin/Motorola environment. The ECoS DCC system supports NMRA DCC, Marklin/Motorola format and Selectrix modes.

The ESU mfx format was designed by Marklin, but information is hard to come by. They describe it as a bi-phase format.
It looks a lot like DCC with a zero pulse being 100 milliSeconds in duration, and a logical one represented by a 50 mS pulse. Polarity is not an issue.
Control up to 4 solenoids or 8 other loads. Works with any DCC system.
Adds four relay driven outputs.
SwitchPilot Servo V2.0
Designed to drive servos.
ESU is a supplier of both retail and OEM Decoders. Unlike many other decoder suppliers, ESU doesn't supply different versions of OEM and retail decoders. The decoders are identical. For the Australian and North American markets the Select OEM decoder is used and identical to the retail decoders. The user can replace the sound files (as long as they are Select sound files.)
A notable user of Loksound Select decoders with custom sound files is Rapido Trains.
