Abstract: It aims, for example, at enabling to easily check whether information displayed on a label etc. attached to a food product is reliable or not. First, a producer 402 registers an ingredient analysis result of a food product. A terminal apparatus 400b of the producer 402 acquires a verification code verifying a production location and a shipment date and time of the food product, from a verification server apparatus 300, at the shipment of the food product. A storage part 202 of a food product trace apparatus 200 stores the verification code, shipment sender information indicating the producer 402, and registration information indicating whether the producer 402 has previously registered the ingredient analysis result of the food product, upon making the verification code, the shipment sender information, and the registration information mutually corresponding. Next, the producer 402 attaches a label displaying the verification code to the food product, and ships the food product.

Abstract: Includes a base station (2) that measures an uplink interference value of a transmission path when a data error has occurred in reception packets multiplexed by plurality, generates a retransmission request signal of a packet format based on the measured uplink interference value, and then transmits the retransmission request signal to a mobile communication terminal that has transmitted the erroneous packet; and a mobile communication terminal (1) that outputs multiplexed transmission data as a transmission packet during a normal transmission, automatically divides the transmission data into parallel signals according to a retransmission multiplex number based on the retransmission request signal when the retransmission request signal has been received, further multiplexes the parallel signals to generate a transmission packet for retransmission, and outputs the transmission packet to the base station.

Abstract: A small and economical voice packet assembling/disassembling (PAD) apparatus, which includes only one packet assembler/disassembler for a plurality of channels. The packet assembler receives coded voice data from a plurality of CODECs provided for each channel, and assembles voice packets by using the coded voice data. The packet disassembler disassembles voice packets to coded voice data and supplies them to a plurality of CODECs provided for each channel.

Abstract: A data multiplex transmission system including a data multiplexer, a demultiplex controller and a clock generator for terminal interface is disclosed, in which one block of an error correction code of a variable word length whose rate can be easily matched with the multiplex rate is set into one transmission frame. The multiframes of the least common multiple of the number of multiframes such that the multiplex rate which cannot be matched in one transmission frame is matched are set, thereby allowing the bit stuff reference timing to be integratedly handled. Further, transmission frame header information and control data link are provided, thereby allowing the multiplex transmission to be executed in accordance with a predetermined communication procedure.This transmission frame can realize the advanced communication by the header information and control data link. Thus, the data multiplex transmission can be performed with a simple construction while keeping the high efficiency and high reliability.
