The present disclosure relates to an electronic detonation device for a blasting system. The electronic detonation device include: an electronic detonator; a wireless communication module; an electric wire connecting the electronic detonator to the wireless communication module; and a communication module support in which the electric wire is stored in a wound state, with the wireless communication module positioned on an upper surface of the communication module support. The communication module support is provided with a pile part configured to be driven into a ground for fixation, so that the electronic detonation device enables stable communication reliability to be secured by orienting the wireless communication module toward the sky, thereby preventing malfunction during blasting and improving blasting accuracy.

A combustion chamber assembly unit for a fuel-operated vehicle heater includes a combustion chamber housing, a combustion chamber formed in the combustion chamber housing, an evaporator medium for the absorption of liquid fuel and for the discharge of fuel vapor into the combustion chamber, and a heating/ignition device for heating the evaporator medium or/and for igniting a mixture of fuel and combustion air formed in the combustion chamber. The heating/ignition device includes at least one radiation source for the emission of electromagnetic radiation into the combustion chamber and at least one absorption body for the absorption of electromagnetic radiation emitted into the combustion chamber.

Logging apparatus, methods and electronic detonators are presented for logging data, wherein the logger transmits read request messages to preprogrammed electronic detonators without transmitting any delay programming messaging, receives and stores electronic detonator data from a given one of the preprogrammed electronic detonators, and sends a verify command to cause the detonator to update its status flag to prevent the given electronic detonator from responding to subsequent read request messages.
