Abstract: The current document is directed to an improved, remotely controlled, internally powered electronic padlock with enhanced security features that, when mechanically compromised, automatically generate alarms. The improved padlock can be opened via a key card placed in proximity to the improved padlock and can additionally be opened in response to receiving a command from a remote controller via network communications. A remote controller can configure the improved padlock, update the configuration of the improved padlock, unlock the improved padlock, and query the state of the improved padlock. A rotating switch, in combination with a translating latch plate and control logic implemented by stored microprocessor instructions and a microprocessor, detects various types of mechanical compromise and initiates generation of an audible alarm.

Abstract: Methods and apparatus are provided for a model-based diagnostic interface. An apparatus is provided for a diagnostic interface for a system having system data, system information, and a system model having a model nomenclature, the diagnostic interface comprising at least one computational object producing an output responsive to said system data, wherein said at least one object includes a binding of said system data to said system information, wherein said system data is mapped to said model nomenclature before being bound. A method is provided for making a model-based diagnostic interface for a system having system information and system data representing the status of said system, the method comprising the steps of modeling said system to create a system model having a system model nomenclature, mapping said system data into said system model nomenclature, and binding said system data mapped to said system model nomenclature to said system information.

Abstract: The present invention provides increased geographical coverage and system capacity for mobile/portable radio transceivers using adjacent and typically separate radio communication frequency bands. A radio that transceives in just one frequency band is adapted to provide a configurable duplexing arrangement to permit communications in extended frequency bands. Duplexing circuitry is connected between the radio antenna and the radio transmitter and receiver. Depending upon the mode of operation of the radio transceiver, switches are selectively operated for variously configuring the antenna, duplexer circuitry, receiver, and transmitter to permit communications in a first or a second set of transmit/receive frequency bands. In one preferred example embodiment, only a single duplexer is employed connected to the antenna and transceiving circuitry through plural switches.
