Patent ID: 8723640

Claim:
A system comprising: circuitry for determining whether a presence of a wireless signal in a first frequency range below a threshold frequency occurred contemporaneously with an absence of a wireless signal in a second frequency range above the threshold frequency; and circuitry for indicating a regimen compliance status of a subject in response to the circuitry for determining whether a presence of a wireless signal in a first frequency range below a threshold frequency occurred contemporaneously with an absence of a wireless signal in a second frequency range above the threshold frequency, in which the circuitry for determining whether a presence of a wireless signal in a first frequency range below a threshold frequency occurred contemporaneously with an absence of a wireless signal in a second frequency range above the threshold frequency comprises: circuitry for receiving a wireless signal via a device in external contact with a portion of an individual from within the portion of the individual, the individual being the subject, the portion of the subject including a portion of at least one of a head of or a neck of or a torso of the subject, the first frequency range being low enough that the wireless signal in the first frequency range can pass through the portion of the individual, the second frequency range being high enough that the wireless signal in the second frequency range cannot pass through the portion of the individual.
