The invention relates to an analog-to-digital converter (301), comprising several comparators (303) and a reference network, said reference network having several reference elements (302).

The network device uses this home identifier data to formulate a signaling message that it sends towards the appropriate home network to contract a home authentication server.

The sub-arrays of the micro-array are located using a template sub-array.

Selecting an array from among a plurality of arrays in a memory as a reference array.

A single grating is applied over the two detectors and only the detector grating is mismatched with the reference grating.

In order to build a referral network you need to have a referral program.

An initial location of the wireless network device can be calculated based on locations of a plurality of reference network devices.

An initial location of the wireless network device can be calculated based on locations of a plurality of reference network devices.

One or more of the gratings can be a reference grating used to compensate for temperature and other disturbances to the sensors.

d) encourage another IR to change line of referralship;

expanding their referral network to significantly widen the pool of prospects;

Our mining network includes up to 10 levels of friends.

Referral network includes payments for up to 10 levels of friends.

The reference network (115) is coupled to the position server (120) and provides GPS data.

Each of the double-ended sense amplifiers is implemented between two of the memory array banks for sharing use, wherein when one array bank is decoded, the other one array bank serving as a reference array.
