Collaborative linear array

[annathefoodie.livejournal.com]

В данном случае collaborative можно переводить как "совместная"? Речь идет о беспроводных сенсорных сетях и слово встречается также в таких контекстах:

A collaborative reception technique that utilizes the spatial diversity of several sensors to produce an array of collaborative antennas that re-transmit the information (with diversity) to a single node that employs an adaptive spatial processor.

И еще, что такое drain efficiency?

ФОРМУЛА is the drain efficiency of the RF power amplifier.

Большое спасибо!

1) “I think the question everyone is asking about Apple is this,” Steve told me during one of our first interviews. “Does the environment to create the next Macintosh still exist at Apple? Would they know it if they found it?”
Что означает последнее предложение в этом абзаце? О чем они узнают, если обнаружат?

2)The story even dipped into Steve’s relationship with his girlfriend at the time,
Tina Redse, describing how Steve wrote her a long note apologizing for working late one night. Nocera found his single-mindedness lonely. Jobs, who at one point in the article failed to remember if he had curtains in his house, refused to acknowledge feeling any kind of wistfulness or dissatisfaction.
Стив Джобс пригласил журналиста по фамилии Носера, чтобы он написал статью о его компании. У меня затык с предложением Nocera found his single-mindedness lonely. К чему здесь слово lonely?
