Electronic apparatus having improved diagnostic interface
First Claim
1. Electronic apparatus comprising main operative functionality and a power provisioning system for powering the apparatus from an external power source, the power provisioning system comprising:
- a main power supply output for energizing the main operative functionality of the apparatus when said power provisioning system is connected to said external power source, anda standby power source for energizing only a subset of the components of the apparatus when said apparatus is in a standby state in which the main operative functionality is not operational, the apparatus further comprising a self contained subsystem operable independently of the main operative functionality including a memory for storing at least one parameter reflecting an internal state of the main operative functionality, said self contained subsystem being powered by said standby power source and including an encoder for encoding the parameters in an output signal and a transducer for generating a wireless transmission from the output signal, which transmission can be detected in the vicinity of the apparatus, so as to enable the parameter to be received and decoded.

12. A personal computer comprising main operative functionality and a power provisioning system for powering the apparatus from an external power source, the main operative functionality including a processor and data storage means interconnected by a bus system, the power provisioning system comprising:
-
a main power supply output for energizing the main operative functionality of the apparatus when said power provisioning system is connected to said external power source, and a standby power source for energizing only a subset of the components of the apparatus when said apparatus is in a standby state in which at least the processor is not operational, the apparatus further comprising a sell contained subsystem operable independently of at least the processor and including a memory for storing at least one parameter reflecting an internal state of the main operative functionality, said self contained subsystem being powered by said standby power source and including an encoder for encoding the parameters in an output signal and a transducer for generating from the output signal a sound including in-band encoded signals that do not allow a human to understand the parameter directly from the sound, which sound can be detected in the vicinity of the apparatus, so as to enable the parameter to be received and decoded. - View Dependent Claims (13, 14, 15, 16, 17)
