Abstract: A method and device enables improving a signal to noise ratio (SNR) of a backscatter signal received from a radio frequency identification (RFID) tag. The method includes generating a continuous wave (CW) carrier signal at the reader device (step 505). An amplitude modulation (AM) noise component of the CW carrier signal is then detected (step 510). The AM noise component is inverted to an inverted noise signal (step 515), and the inverted noise signal is summed with the CW carrier signal to provide an AM noise cancelled carrier signal (step 520). The AM noise cancelled carrier signal is then transmitted from an antenna of the reader device (step 525), and the backscatter signal is received at the reader device in response to transmission of the AM noise cancelled carrier signal (step 530).

Abstract: By pushing the registration switch of a main controller, a radio signal for requesting the transmission of a terminal-device ID number is transmitted (SP1, SP2). A wireless sensor sends back the terminal-device ID number (SP11, SP12), and the main controller stores the received terminal-device ID number in its storage unit and transmits a main-controller device ID number (SP4, SP5). The wireless sensor stores the main-controller device ID number in its storage unit. From then on, communications between devices whose device ID numbers have been registered are permitted.

Abstract: An identification and verification security badge is disclosed. The badge includes a keypad that allows the entry of user information that is monitored and verified by a processor within the badge. The processor compares an inputted personal identification number with one that is stored within a memory within the badge. When a match is found, an access code is transmitted that includes at least a badge identification code that uniquely identifies the badge. The badge also includes an on-body sensor that determines the status of the badge with respect to a user. When the sensor determines that the badge is not in close proximately to the user, then transmission from the badge is inhibited. In another aspect, when a transition from one state of the badge sensor to another state is determined, the personal identification number is required to be entered.

Abstract: A method and system for identifying an authentication status of a first item. An RFID reader transmits zero and a random number to a first RFID tag associated with the first item. The first RFID tag uses a hashing function to compute a hash (H1) of a concatenation of an identifier (Id1) of the first RFID tag, the random number, and a first secret key and sends the hash H1 to the RFID reader which then transmits the identifier Id1 and the random number to a second RFID tag. The second RFID tag uses the hashing function to compute a hash (H2) of a concatenation of the identifier Id1, the random number, and a second secret key and sends the hash H2 to the RFID reader. The authentication status of authentic or counterfeit is determined for the first item based on whether or not H1 is equal to H2.

The first sensor layer includes at least one signal path extending the first sensor layer. The first sensor layer may be provided by either a fiber optic or a wire. An inability of the at least one signal path to conduct a signal from a first end to a second end represents either a breach, or an attempted breach, from outside the container or a failure of the container. The containment layers may seal against any leakage of material in a container subsequent to a breach either from within or from without. An additional layer may be provided to protect against intrusion and may be made from material such as Kevlar. The detection and containment system may be implemented to protect tunnels, pipelines, hatches and manhole covers.

Abstract: A method and a system are provided for controlling a controller without physically touching the controller. A hand or other object interacts with a field surrounding the controller, altering the field. A change in characteristic of the altered field causes a corresponding movement of the controller that, in turn, corresponds to an amount of change in a parameter of a target device being controlled by the controller. The parameter of the target device is controlled by the controller while a user has no physical contact with the controller.

Abstract: A method for detecting an intruder in a protected space that uses a microwave frequency sensor to determine an accurate distance measurement to the intruder. The accurate distance measurement reduces the false alarms typically associated with microwave frequency sensors due to motion outside the protected space and vibration within the protected space. The motion detector transmits three microwave frequency signals of different frequencies in order to eliminate an ambiguity problem when determining the accurate distance measurement. The accuracy of the intruder distance measurement may be determined with greater resolution by reiteratively transmitting and evaluating microwave frequency signals of different frequencies. The motion detector of the present invention may include a PIR sensor.
