Abstract: A system and method for a dynamically configurable security system, comprising, a security service module capable of dynamically instantiating one or more plugin security provider modules, the one or more security provider modules are coupled to the security service module wherein the one or more security provider modules are capable of responding dynamically to changes in configuration information, wherein the security service module is capable of receiving one or more security information updates, and wherein the security service module is capable of controlling access to one or more resources based on the one or more security information updates.

Abstract: An airport communication system (1) has a tag (10) affixed by a clip (12) to each passenger en route between check-in and boarding. Each tag (10) transmits an identifier on a particular RF channel with a short range, and the location of a transponder (5) which received the transmission indicates passenger location. A server (4) correlates tag and passenger identifiers and generates alerts if alert conditions are met such as excessive distance from a boarding gate at a particular time.

Abstract: Disclosed are methods and apparatus for effectively provisioning services for access by other entities or services. In general, a service manager is configured to manage the provisioning of services between remote entities within a computer network. In general terms, a remote entity offers a service to another remote entity through the service manager. The service manager facilitates formation of the offer to one or more Invitee(s) specified by the service provider. After an offer is formed, it may then be provided to the specified Invitee(s). After an Invitee receives an offer, the Invitee may accept the offer through the service manager or let the offer expire. The service manager also preferably tracks the status of each offer and whether each specified Invitee has accepted such offer. After an Invitee accepts an offer, the service manager preferably records information sufficient for the Invitee to use the offered service.

Abstract: A new and distinct variety of Prunus persica is provided. The new peach tree variety produces an attractively colored, yellow fleshed, clingstone peach that matures early in the season (7-10 days after Flordaking) under the ecological conditions prevailing in the medium chill zone of south central Texas and is adapted in the medium chill region. The variety requires approximately 450 chilling units of dormancy.

Abstract: A method and apparatus for synthesizing an approximation to a sine wave comprising generating a number of pulse width modulated signals, each having a predetermine duty cycle and being the same frequency as each other, from a clock signal. The generated pulse width modulated signals are then combined to produce an approximation to a sine wave having the same frequency as the pulse width modulated signals. The clock signal is provided by an oscillator arranged to produce clock signals over a continuous range of frequencies so that approximations to a sine wave can be produced over a continuous range of frequencies.

Abstract: A method and apparatus for determining the speed of sound in a gas. An acoustic transmitter is arranged to apply an acoustic signal to the interior of a resonator and an acoustic receiver is arranged to detect the amplitude of the acoustic signal in the interior of the resonator. A control means determines the speed of sound of gas within the resonator from the frequency of a detected non-radial resonant mode.
