Device failures (hard failure or soft failure
), medical conditions (infection, acute or chronic otitis media, and implantation cholesteatoma) and electrode array extrusion or misplacement are frequent causes of CRI (1).
After a session with Alberto at Google headquarters in Palo Alto, I realised the importance of creating an ecosystem for innovation within a framework of soft failure
, where marketers and agencies can try different approaches before products and marketing strategies come to real life.
[sup] analyzed histopathology of temporal bones of 8 subjects who had experienced a soft failure
. Foreign body or hypersensitivity reaction was observed in 6 (75%) of the cases, which meant that foreign body reactions were rare, but might be more common than we realized.
If a soft failure
that is expected in HASS disappears or new soft failures
appear, something has changed that needs looking into.
The protection circuit provides an indication of the severity of the problem, from a hard failure requiring immediate attention to a soft failure
that can be remedied at a later time.
The hard and soft failure
points identify the initial precipitation and detection limits for HASS.
A soft failure
is a temporary failure that may be corrected (or will correct itself) without replacing the failed component.
S-band frequency Current power out of 12 kW Future(*) power out of 20 kW Si bipolar devices 224 transistors with hybrid, radial and waveguide combiners Features soft failure
, replacement during continuous operation
Test engineers determined that the oscillator for the MCC was causing the soft failure
, which was fixed when the temperature was reduced to 60[degrees]C.
: Failure of a product under test that reverts to correct operation when the test stresses are reduced.
In this effort, without any loss of generality, only two specific classes of failures have been considered, that is, step failure and ramp failures to simulate the injection of hard or soft failures
. For each of these cases, the magnitude of the failure was also varied to test the fault sensitivity.
