Abstract

In one embodiment, an apparatus includes a first assembly, a second assembly, and a coupling element coupled to the first assembly and the second assembly. The first assembly includes a processor, a memory, and a radiator module, the processor operatively coupled to the memory and the radiator module. The second assembly includes a radiator operatively coupled to the radiator module. The second assembly is movable relative to the first assembly about the coupling element between a first configuration and a second configuration. The processor is configured to interrogate a radio-frequency identification module via the radiator module and the radiator when the second assembly is in the second configuration.

Claims

2. A system comprising:

a processor module including a communications interface, wherein the processor module is configured to send one or more interrogation signals via the communications interface;

a first radiator module in communication with the processor module and one or more first radiators; and

a second radiator module in communication with the processor module and one or more second radiators;

wherein each of the first radiator module and the second radiator module is configured to,

in response to receiving an interrogation signal from the processor module, interrogate at least one radio-frequency identification tag via its respective one or more radiators,

receive at least one interrogation response via its respective one or more radiators, and

communicate an identifier and response information to the processor module, wherein the response information comprises one or more of a response time of the at least one interrogation response and a signal strength of the at least one interrogation response,

wherein the processor module is further configured to

receive the identifier and the response information from each of the first radiator module and the second radiator module, and

triangulate a position of the at least one radio-frequency identification tag within an enclosure based on the received identifiers and response information,

receive a request for access to the at least a portion of the interrogation response, wherein the request for access comprises a credential;

determine that the credential is authorized to access the at least a portion of the interrogation response based on an access permission associated with the at least one radio-frequency identification tag module;

provide access to the at least a portion of the interrogation response based on the credential.

7. A method comprising:

receiving, at a processor module, an interrogation command;

determining, at the processor module, a geographic location of a device having the processor module, a first portion of the device being moveable relative to a second portion of the device between a first configuration and a second configuration;

determining whether the geographic location of the device is within a predefined geographic region;

if it is determined that the geographic location of the device is within the predefined geographic region, responding to the interrogation command by interrogating one or more radio-frequency identification tags, and sending, from the processor module, an interrogation result via a communications interface; and
