The photo survey service system of the invention comprises an image information receiving means 12 for receiving image information from customer's terminal equipment 8 via a telecommunication circuit network 10, which image information is obtained by taking photographs of an area 4 under survey having a plurality of stations 2-1, 2-2, . . . 2-n from a plurality of points using a digital camera 6 at a fixed focal length, an analysis processing means 14 which uses computation processing to calculate a three-dimensional vector relation of each station from the received image information on the basis of a difference in parallax between both images of adjacent photographing points, and an analytical result transmitting means 16 for transmitting information on the calculated three-dimensional vector relation of each station to the customer's terminal equipment 8 via the telecommunication circuit network 10.

A mobile telecommunication device including at least one telecommunication circuit; at least one subscriber identification module; at least one assembly including at least one supply battery; and a switch of selection between a power supply of the subscriber identification module by the assembly and by the telecommunication circuit according to the presence or not of a near-field communication module in the assembly.

According to the invention, systems and methods are provided for analyzing the diversity of a set of critical telecommunication circuits. For example, according to one embodiment of the invention, a method is provided for analyzing the diversity of critical telecommunication circuits, the method comprising: determining a critical circuit set comprising a first critical circuit and a second critical circuit; identifying a first set of telecommunication resources associated with the first critical circuit; identifying a second set of telecommunication resources associated with the second critical circuit; and comparing the first set of telecommunication resources with the second set of telecommunication resources to determine whether the critical circuit set is diverse.

Embodiments according to the present invention allow multiple parties equipped with telecommunications devices (endpoint devices) of similar or differing audio capabilities to join in a conference call and enjoy the fidelity associated with their equipment. Rather than operating with the frequency and fidelity limits of traditional telecommunications circuits (for example, about 300-3500 Hz), at least a portion of a conference bridge according to the present invention operates at higher frequencies. Conference participants using high-fidelity endpoint devices hear each other with greater clarity and reproduction accuracy. Conference participants using conventional interfaces send and receive lower-fidelity audio, but it affects only their own participation and not that of the entire conference. Participants can connect via for example, wireline, wireless Public Switched Telephone Network (PSTN), or via networks such as the Internet. Multiple voice encoding schemes are accommodated.

The invention relates to an ultra-low power consumption long-distance electrocardiogram data wireless acquisition system. The wireless acquisition system adopts ANT (antenna) +GPRS (General Packet Radio Service) heterogeneous networking to match with an electrocardiogram acquisition band, solves the acquisition of mankind electrocardiogram data during exercises, enables coaches and athletes to deeply know intensity of training in order to improve exercise effect and also can satisfy the huge requirements of domestic medicine and health supervision for monitoring cardiac rates. The wireless acquisition system comprises an electrocardiogram data acquisition band and a wireless data retransmitting device, wherein the electrocardiogram data acquisition band comprises an electrocardiogram acquisition treatment circuit and a lead electrode, and the wireless data retransmitting device is a topological structure network comprising a remote telecommunication circuit and a main control computer. Compared with the prior art, the wireless acquisition system realizes the wireless acquisition of mankind electrocardiogram data during exercises, adopts an ANT+GPRS heterogeneous networking structure and realizes the low-power consumption long-distance transmission of data. The electrocardiogram data acquisition band has light and simple structure, is easy to wear by a measured human body and does not influence the motion and the daily activities of the measured human body.
