Q

Why does AB place emphasis on the systems output circuit(s)?

A

It is the key feature that allows signinficant flexibility in sound processing and sets us apart from our competitors.
Can produce different waveforms on a channel by channel basis
allos the capability to stimulate sequentially, partially simultaneously or fully simultaneously
**We have 16 independent output circuits

Q

What is a capacitor?

A

An electrical component that holds a charge

17
Q

Why are capacitors important?

A

They provide protection agains leakage of harmful DC current which can damage neural tissue.
Charge-balanced, which is important with faster stimulation rates
hilds excess charge (+/-) to ensure that a baslanced pulse is delivered to the nerve.

18
Q

What is Telemetry?

A

Bi-Directional Communication
The capability to send info in both directions
Monitors the communication between the internal and external hardware
essential for audible alarms/LED, measuring impedances and power management
Uses RF or radio frequency

19
Q

Describe the forward and backward telemetry

A

Forward-sends across data and power info
Backward (Backtel)-provides info about status of the implant. Allows contiual monitoring of function of the system. Impedances Measures!

20
Q

What allows for impedance measurments and info on status of the implant?

A

Backward Telemetry or Backtel

21
Q

What are the RF carriers for Forward and Backward Telemetry?

A

Foward-49 MHzWhat

Backward-10.7 MHz

22
Q

What are the HiRes 90K Advantage electrode options?

A

1-J
Helix
Mid-Scala

23
Q

What makes the HiRes 90K Implant Family unique?

A 
Low-profile titanium housing
MRI-safe with magnet removed (0.3 and 1.5 Tesla)
IntilliLink
Eletrode options
Upgradeable electronics platform
24
Q

What is IntelliLink and why is it important?

A

Allows for recognition of the interal device serial number. Provides safety because an external processor cannot be stimulated by the wrong internal device.

25
Q

AB reports for the 2012 Reliability Report what CSR?

A

99.83%

26
Q

What features of our internal device allows us to say “Unmatched technology”?

A

16 independent current sources which allows for:
unlimited ways to process sound
Fastest stimulus rates
Industry’s highest case impact resistance (up to 6 joules)

27
Q

What is Total System Reliability mean?

A

Internal reliability
Naida CI is guaranteed water resistant (now IP 68 with Aqua Case)
Neptune is guaranteed water proof
recipients can count on hearing everyday, all day!!

28
Q

What is new in SoundWave 2.2?

A 
CPI-3
New features like Ultrazoom...etc. and binaural voice stream technology (DuoPhone, ZoomControl, Quick Sync and Direct Touch)
Flexibility of mic sources
Access to Optima
Flex NRI
Support for AB myPilot and ComPilot
