A commodity promotion system includes output unit that presents a customer with information, commodity presence/absence determination unit that determines presence or absence of the target article on the basis of signal strength information of the RF tag, commodity information storage unit that stores commodity information list in which the tag information of the RF tag, commodity presence/absence information indicating presence or absence of the target article, output unit ID information of the output unit, and output information indicating information to be presented are associated with one another, and commodity pickup determination unit that detects that the target article has changed from a presence state to an absence state, on the basis of a determination result of the presence or absence of the target article and the commodity presence/absence information in the commodity information list and outputs the output information associated with the tag information to the output unit.

Commodity promotion system and non-transitory computer-readable medium storing program therefor

A noise suppression structure for suppressing an undesired high-frequency current in a transmission line (i.e. a sleeve) of a short-circuited termination type includes a conductor base encompassing the periphery of the transmission line and a conductor short-circuiting part which is connected to the transmission line at the opposite side to an open end of the conductor base and whose inductance is greater than that of the conductor base. It is possible to increase an inductance by modifying the shape of the terminal end of the sleeve, equivalent to a quarter wavelength of an undesired high-frequency current which occurs in a wireless circuit of a mobile wireless terminal and flows through a ground layer, thus reducing the entire length and realizing miniaturization while securing desired input impedance.

Noise suppression structure

A technique is proposed for reducing leakage electromagnetic field that reduces the electromagnetic leakage from a connection point between a communication coupler and a signal transmission apparatus and that can conduct both communication and transmission of electric power. The signal transmission apparatus includes: a first sheet conductive body portion constituting a lower portion electrode; and a second sheet conductive body portion in a mesh shape which is laminated on the first sheet conductive body portion while a gap area is sandwiched therebetween and which includes an uneven mesh size area on which a sheet impedance is continuously changed.
