Abstract: A system with an intelligent shelf (100) has product display shelves (110 to 130) displaying products having RFID tags R. The system includes antennas (112a to 112c) each having unique antenna numbers and detecting a tag serial number from an RFID tag on a product, human body sensors S disposed on each end of the product display shelf 120, a tag-product ID registration table storing the tag serial numbers of the RFID tags and the product IDs of the products and a control computer (200) detecting that a particular product is picked up from and/or returned to a particular product display shelf by combining the input tag serial number and the antenna number of the antenna detecting the tag serial number and analyzing which direction the detected human body has moved based on the difference of the detection times of the human body sensors.

Abstract: [OBJECT] To provide system and program for obtaining customers' purchase behavior information for products. [MEANS FOR ACHIEVING OBJECT] A system comprising an intelligent shelf (100) having product display shelves (110 to 130) on which the products A to C applied with RFID tags R are displayed, a plurality of antennas (112a to 112c) each having unique antenna numbers and detecting a tag serial number from an RFID tag on a product, a pair of human body sensors S disposed on each end of the product display shelf 120, a tag-product ID registration table storing the tag serial numbers of the RFID tags and the product IDs of the products uniquely given to each kind of product and a control.

Abstract: To provide a steering wheel which is lightweight, and which has adequate strength and shock resistance, a carbon fiber prepreg 13 is wound on a mandrel 11 or a lightweight foam core 40 so as to obtain a preformer 14. By heating this preformer 14 in a mold 18, a steering wheel is obtained wherein the rim is formed from a fiber-reinforced synthetic resin joined to a metal skeleton 23.

Abstract: In a connector whose exposed terminals are connected to a mating connector having a terminal portion of a flexible printed circuit, the invention provides a terminal cover structure which prevents terminals from being exposed when the connector is disconnected. The terminal cover structure has a slidable protective cover that protects the exposed terminals of the connector. With the protective cover retracted, the exposed terminals are brought into contact with the exposed terminal portion of the mating connector. Either of the protective cover or the mating connector is provided with an engagement portion which consists of resilient clamping pieces to draw out the protective cover. The other is provided with a second engagement portion that engages with the first engagement portion.

Abstract: Disclosure is a connector terminal holding mechanism which assures that a terminal received in a connector housing can reliably be held in the latter. The connector terminal holding mechanism for reliably holding a terminal including an upright standing engagement portion and an engagement shoulder located forward of the upright standing engagement portion in a connector housing with a rear holder including an engagement portion adapted to be engaged with the upright standing engagement portion is constructed in the improved state in such a manner that a plurality of guide rails each including a raised portion having a height in excess of that of the upright standing engagement portion are formed in the connector housing, and the rear holder merges into an engagement projection including a plurality of slidable portions adapted to be slidably engaged with the guide rails and a plurality of engagement portions adapted to be engaged with a shoulder portion of a box-shaped portion on the terminal.
