Abstract: A method for continuous, non lot-based manufacturing of integrated circuit (IC) devices of the type to each have a unique fuse identification (ID) includes: reading the fuse ID of each of the IC devices; advancing multiple lots of the IC devices through, for example, a test step in the manufacturing process in a substantially continuous manner; generating data, such as test data, related to the advancement of each of the IC devices through the step in the process; and associating the data generated for each of the IC devices with the fuse ID of its associated IC device.

Abstract: Methods and apparatus for determining carrier frequency error of a serial offset quadrature pulse shaped signal, such as a minimum shift keyed (MSK) signal, are disclosed. Carrier frequency error is determined by receiving a quadrature pulse shaped signal having a synchronization sequence, detecting synchronization of the quadrature pulse shaped signal, and storing a baseband inphase (I) signal and a baseband quadrature (Q) signal of the synchronization sequence while detecting synchronization. After detecting synchronization, segments of the stored baseband I and Q signals are read and correlated with a spreading sequence. Carrier frequency error is then estimated based on phase differences between each of the correlated segments.

Abstract: A communication method and apparatus includes a transmitter of radio-frequency electromagnetic energy (RF) at a first location. A passive, modulated reflector at a second location reflects incident RF, and is modulated by information to be communicated. The reflected RF thus includes the information. A receiver remote from the reflector receives the reflected, modulated RF and extracts the information therefrom. The receiver may be co-located with the transmitter.
