  • the storage interface 734 can connect to a standard computer readable medium for storage and/or retrieval of information, such as a fixed disk drive 744.
  • the fixed disk drive 744 may be a part of a computer system 700 or may be separate and accessed through other interface systems.
  • the network interface 748 may provide multiple connections to the networked devices.
  • the modem 746 may pro vide a direct connection to a remote server via a telephone link or to the Internet via an Internet service provider (ISP).
  • the network interface 748 provides one or more connections to a data network, which may consist of any number of other network-connected devices.
  • the network interface 748 may provide such a connection using wireless techniques, including digital cellular telephone connection, Cellular Digital Packet Data (CDPD) connection, digital satellite data connection or the like.

  • a signal can be directly transmitted from a first block to a second block, or a signal can be modified (e.g., amplified, attenuated, delayed, latched, buffered, inverted, filtered, or otherwise modified) between the blocks.
  • a signal can be directly transmitted from a first block to a second block, or a signal can be modified (e.g., amplified, attenuated, delayed, latched, buffered, inverted, filtered, or otherwise modified) between the blocks.
  • modified signals e.g., amplified, attenuated, delayed, latched, buffered, inverted, filtered, or otherwise modified
  • a signal input at a second block can be conceptualized as a second signal derived from a first signal output from a first block due to physical limitations of the circuitry involved (e.g., there will inevitably be some attenuation and delay). Therefore, as used herein, a second signal derived from a first signal includes the first signal or any modifications to the first signal, whether due to circuit limitations or due to passage through other circuit elements which do not change the informational and/or final functional aspect of the first signal.

Abstract

L'invention concerne des systèmes, des appareils et des procédés qui sont conçus pour surveiller et gérer une pluralité de capteurs. La pluralité de capteurs peut comprendre des capteurs fixes, mobiles, ou une combinaison de ceux-ci, et dans certains modes de réalisation, la surveillance et la gestion des capteurs est facilitée au moyen d'une interface graphique utilisateur.
