An apparatus for providing a temperature based alerting signal to a user to alert the user to the occurrence of a particular or predetermined event. The temperature based alerting device may be incorporated into jewelry, garments, or a releasable strap and includes at least one spot heating element that is maintained in substantial contact with the users skin. Upon detected occurrence of the predetermined event, as for example an incoming telephone call or page, the user is silently alerted by a change in the temperature of the spot heating element in contact with the users skin. Subsequent action by the user, as for example answering of the incoming call or page, causes the temperature based alerting device to reset to an initial, non-alert state.

A system for automatically locating a personal electronic object is described. The system comprises: a communicator; a location sensor; and a security controller. The security controller activates the location sensor to determine a location of the personal electronic object. When security of the system is compromised and access to a computer network or a wireless network is available, the location is transmitted through the communicator.

A pump source for a fiber Raman amplifier is formed to include a polarization scrambler to reduce the effects of polarization dependent gain, particularly as used in a multiple input wavelength WDM optical system. The source utilizes a polarization scrambler coupled to the output of a pump laser, the scrambler controlled by a sinusoidal input signal to impart a randomness to the polarization of the pump signal. Thus, a random state of polarization of the pump signal, with respect to the various input signal wavelengths, improves the overall gain experienced by the system.

An arrangement for monitoring the performance of each pump source in a fiber Raman amplifier arrangement utilizes a set of unique âsignatureâ signals, each signature signal impressed on a different pump input signal. At the receiver, the signature signals are extracted from the received, amplified signal. If a particular signature signal is missing at the receiver, this is indicative of failure of its associated pump source at the transmitter. If a particular signature signal is noticeable weaker than other received signature signals (as evidenced by, for example a low SNR or high BER), this is indicative of a power loss in its associated pump source. Since each signature signal is chosen to be unique, the identity of each pump source can be easily ascertained. In one embodiment, a low data rate signal is impressed on an RF signal used to modulate the pump prior to be applied to the transmission fiber. Alternatively, the RF modulation signal associated with each pump source can be offset by a predetermined frequency and the frequency offset used as the signature.

A monitoring and tracking system for monitoring and tracking an object may have a plurality of object area network elements. Each of the object area network elements may have a wireless communications unit and a GPS unit, wherein the GPS units are designed to facilitate the calculation of position data for each of the plurality of object area network elements. The wireless communications units may be designed to facilitate communications between the plurality of object area network elements and at least one base station. Each of the plurality of object area network elements may further have a sensor unit, the sensor units each having at least one temperature sensing unit for obtaining temperature data and at least one pressure sensing unit for obtaining pressure data. The object area network elements may be designed to communicate the temperature data, the pressure data, and the position data to the base station. The plurality of object area network elements may also be designed to communicate with each other to form an object area network.

A system and method for automatically maintaining the security of an area. In one embodiment of the invention, several space area network elements may be placed near or in a circular pattern around an area to be kept space, such as a school. The space area network elements are devices including sensors to sense the presence of an unwanted object such as a gun. The space area network elements may also include a wireless communication unit so that when the presence of an unwanted object or gun is sensed, a third party entity such as a the police may be alerted. The space area network elements also include inter-element communication units that allow the space area network elements to share information and form a space area network. Additionally, the space area network elements may include a positioning system unit that obtains data related to the position of the space area network. By way of the positioning system unit, position information may also be communicated to the third party entity.

A wireless means of guidance for a device in accordance with the present invention includes receiving signals from at least one wireless base station indicating at least a respective position thereof, determining the current position of the device using at least the information contained in the received signals, calculating a vector between the determined current position and a predetermined desired destination for the device, and making trajectory corrections to the devices current trajectory so as to guide the device to the desired destination. In addition to the information contained in the received signals, the guidance system may also use stored information regarding parameters, such as the location, communication protocols and operating frequencies of the wireless base stations, as well as previous position information, for determining a current position for the device.
