Method and system for providing location dependent and personal identification information to a public safety answering point

A method and system are provided for sending location dependent and personal identification information to a public safety answering point. Base stations for receiving a transmission packet signal having a transmitter identification number are located throughout an area where personal security coverage is desired. Whenever a personal security transmitter is activated, it is received by one or more base stations. Each base station has a signal receiving unit for receiving a transmission packet signal and a signal processing unit for processing a transmission packet signal and generating a base station packet. Base station packets contain both a transmitter identification number and location information about the activated transmitter. After a base station packet is generated, it is sent to a command center for processing. If a valid base station packet is received at a command center, information contained in the base station packet is used to determine the closest base station to the activated transmitter and to retrieve personal identification information about the person to whom the transmitter was issued. This location and personal identification information is then displayed at the command center or public safety answering point.

Personal security manager for ubiquitous patient monitoring

The present invention relates to a system and corresponding method for a secure end-to-end patient healthcare system which includes wireless medical sensors adapted to be attached to a patient's body and in communication with each other forming a body sensor network within a wireless medical sensor network including one or more body sensor networks; λ-secure keying means incorporated into each wireless medical sensor for enabling secure communications between the wireless medical sensors, and a personal security manager within the body sensor network and in communication with the wireless medical sensors within the body sensor network, the personal security manager providing secure communications with backend services and providing security relationships within the body sensor network by means of the λ-secure keying means, wherein the λ-secure keying means are such that a coalition of no more than λ compromised wireless medical sensors conceals a pairwise key between any two non-compromised wireless medical sensors and provides protection against node compromise until λ+1 wireless medical sensors have been compromised.

The invention belongs to the field of construction safety monitoring and wireless communication and discloses a construction tunnel safety protection method based on a wireless sensor network and a monitoring system thereof. The method is as follows: by acquiring environment, work amount and locating data of personnel in a tunnel, realizing alarming services of six types of dangerous situations and corresponding safety protection means, calling a protection plan to take protection measures on key parts of the system when emergent (dangerous) events occur, and with the purpose of guaranteeing personal safety, releasing a control command. The system comprises a wireless sensor network based on industrial wireless communication standard WIA-PA, a positioning network and a mobile network. If the dangerous situation develops further, the system exchanges data with a remote mobile server by a 3G network, leads a community security system into the range of a construction tunnel safety protection system, and provides united rescue of communities and disaster control services. The invention is used for tunnel construction safety monitoring, and a computer or 3G mobile equipment can obtain construction site information at any time; and the installation of the WIA-PA wireless network is flexible, and the formed safety protection system and sensing early-warning network make contribution to solving the problem of tunnel safety construction fundamentally.
