A wireless communicator-indicator for communicating with a management apparatus that manages progress in a picking operation includes: an indication unit that provides an indication for mating an operator recognize a position of a picking target item; a first wireless communication circuit that receives indication instruction information transmitted from the management apparatus by a radio wave, and records or outputs electronic information reflecting the indication instruction information with energy of the received radio wave; an operation accepting unit that accepts an operation relating to picking operation completion; a power supply circuit; a second wireless communication circuit that transmits picking operation completion information with power of the power supply circuit; and a controller that controls the indication unit to provide an indication on the basis of the electronic information, and controls the second wireless communication circuit to transmit the picking operation completion information on the basis of the accepted operation.

Wireless communicator-indicator

A walking assistance device includes: a base body; a driving unit that moves the base body; a distance detection unit that detects a distance from the base body to a user; a safety distance range setting unit that set, as a safety distance range, a distance range from the base body to the user during safe walk of the user; a walking state determination unit that determines whether or not the distance detected by the distance detection unit is out of the safety distance range; and a control unit that controls the driving unit when the walking state determination unit determines that the distance is out of the safety distance range. The walking assistance device detects that the distance is narrower than a predetermined distance, wherein the driving unit is controlled when the approach determination unit detects that the distance is narrower than the predetermined distance.

Walking assistance device

There is provided a board layout check apparatus for checking whether or not a guard wiring is appropriately formed, wherein a place which must be corrected is clearly displayed. The board layout check apparatus includes a printed board obtained by forming a guard wiring on a printed wiring layer, a check target wiring detecting unit which detects a check target wiring the influence of noise of which must be reduced from the printed wiring layer, a guard wiring exemption region calculating unit which calculates a guard wiring exemption region in which no guard wiring is formed for the check target wiring, a guard wiring detecting unit which detects a wiring portion in which a guard wiring is formed for the check target wiring, an error determination unit which determines whether or not the guard wiring is appropriately formed in a region except for the guard wiring exemption region, and an output unit which outputs a wiring portion determined as an error by the error determination unit.

Board layout check apparatus and board layout check method for guard wiring

A printed board includes: an impedance matching member disposed along the periphery of a plurality of connecting pins for connecting a connector to signal lines on the printed board, the plurality of connecting pins being arranged in row and column directions; and a connecting portion for connecting the impedance matching member to a ground line of the printed board. The printed board according to the present invention is capable of suppressing the impedance mismatching of an ordinary connector having no special shield or the like for impedance matching.

Printed board

A layout designing/characteristic analyzing apparatus for a wiring board includes a module library memory for storing in advance for each of wiring board modules which are constituents of the wiring board, moduled circuit information on moduled circuits which constitute a wiring board circuit, wiring information and an analysis model for use in characteristic analysis; an input section for inputting instructions on connection of the moduled circuits so as to construct a desired circuit; a module coupling section for connecting moduled circuits based on the inputted instructions, for determining a layout of the wiring board based on the wiring information of each module and for generating a coupled analysis model in which the analysis models of the modules are coupled; a characteristic analyzing section for analyzing the characteristics of the wiring board based on the generated coupled analysis model; and an output section for outputting the determined layout and the results of the characteristic analysis of the wiring board.
