Digital mapping techniques are disclosed that provide more flexibility to the user through the use of multiple views of map information, including a secondary map and a main map. The secondary map can provide the user with either a zoomed out or in relative to the main map, or a different type of map view (e.g., satellite images). The secondary map can be turned on and off by the user. The secondary map may include one or more viewing frames that indicate views (e.g., current and alternate views) of the main map. The user can move the main map, viewing frame, or secondary map to achieve desired map views. During such movement, the relationship between the main and secondary maps can be synchronous, partially synchronous, or serial.

A method locates a mobile node in a partially synchronized wireless network comprised of nodes with heterogeneous communication ranges. The time intervals it takes for messages to travel from stationary nodes at known location to a mobile node at an unknown location are measured and used to determine a set of possible coordinates of the mobile node. This time-based set of coordinates is in the form of a hyperbolic function. The received signal strengths of a message received from the mobile node is measured in two additional stationary nodes at known location. These RSS-based measurements provide two more sets of possible coordinates of the mobile node. The three sets are then intersected to estimate the location of the mobile node.

A TSP signal that is a measurement signal is generated N times by a signal generating portion. The generated TSP signals are supplied to a steel-echo apparatus. Reverberation generated by the steel-plate echo apparatus corresponding to the TSP signals is arranged N times corresponding to the start points of the TSP signals and synchronously added by a synchronously adding portion. Generating impluse signal is convoluted by an inverse function to TSP signal. The added result of the synchronously adding portion is supplied to an impulse response converting portion. By dividing the added result by the inverse characteristics of the TSP signals, the added reverberation is converted into an impulse response. The impulse response data obtained by the converting portion is recorded to for example a CD-ROM and supplied to a reverberator. The reverberator reproduces an impulse response recorded on the CD-ROM and performs a convolution calculation process for the input signal. Thus, reverberation of the steel-plate echo apparatus can be reproduced.
