A mobile communication system including a plurality of base stations arranged in a communication area, each emitting a radio wave inherent thereto and a mobile station moving in the communication area and communicating with respective base stations via the transmitted radio waves. There is previously stored a location correlation data group including correlation data representing correlation situations of a plurality of arriving radio waves produced by the transmitted radio waves at respective ones of a plurality of sampling locations within the communication area, the location correlation data corresponding to respective locations. Upon reception of radio waves at a current location of the mobile station, current correlation data is calculated representing correlation situations among received arriving radio waves for the respective mobile station. The location correlation data in the location correlation data group is compared with the current correlation data, and the current position of the mobile stations is determined in accordance with a result of the comparison, generating the determined current position data.

In an online marketplace environment, a seller of items can provide information relating to items for sale on one or more online sales channels to a connection provider. In one implementation, a method describes receiving a product data file (PDF) from a seller, in which the product data file includes information relating to one or more items for sale by the seller. The method also includes facilitating a sale of the one or more items through one or more online sales channels, in which the product data file further includes one or more data fields for enhanced selling features. The enhanced selling features include selling features in addition to baseline features. The baseline features include providing online listing capabilities for the one or more items being sold.

A code error correcting circuit interleaves original data comprising a sequence of bit data having a length of p bits by arranging the bit data of the original data into a hypothetical matrix of I rows and J columns and then selecting the bit data positioned on the ith row along an order of the jth column. The circuit is provided with a memory unit having a plurality of memory areas each having a length of 2n bits; and a controller for storing the original data to be interleaved into the memory areas respectively. The bit data, which are indicated by a bit select data, stored in the memory unit are sequentially outputted along an order of the ith row and the jth column in the hypothetical matrix as the interleaved original data.

An eyepiece lens has an apparent field of no less than 40.degree., and minimizes eye relief error. The eye relief includes a distance between a lens surface closest to an eye point side in the eyepiece lens and an eye point. The eyepiece lens comprises an assembly of lens groups including, from the eye point, a first lens group G.sub.1 that includes one positive lens component, a second lens group G.sub.2 with positive refracting power that includes a cemented lens having a negative lens component and a positive lens component, a third lens group G.sub.3 with positive refracting power that includes a cemented lens having a positive lens component and a negative lens component, and a fourth lens group G.sub.4 that includes one negative lens component. The assembly of lenses is configured such that 1.4.ltoreq..vertline.R7/R4.vertline., wherein R4 is a radius of curvature of a cemented surface of the negative lens component and the positive lens component of the second lens group G2, and R7 is a radius of curvature of a cemented surface of the positive lens component and the negative lens component of the third lens group G.sub.3.

Eyepiece lenses are disclosed that provide a wide apparent field of view (.gtoreq.40.degree.) and that effectively correct optical aberrations even to the periphery of the apparent field of view. The eyepiece lens comprises, in order from the eye side, a first lens group G.sub.1 comprising a positive lens element, a second lens group G.sub.2 having positive refractive power and comprising either a positive lens element cemented to a negative lens element, or a negative lens element cemented to a positive lens element, and a third lens group G.sub.3 having positive or negative refractive power and comprising a positive lens element cemented to a negative lens element. At least one lens surface is aspherical. The eyepiece lens satisfies any of various quantitative expressions.
