A method and apparatus for measuring a channel quality in wireless transmit/receive units (WTRUs) which are equipped with a subscriber based smart antenna. The WTRUs are equipped with a smart antenna so that the WTRU generates a plurality of directional beams and, optionally, an omni-directional beam. A dwell time is provided in a measurement period to switch a beam from an active beam to a non-active beam. The active beam is one of the plurality of directional beams or, optionally, the omni-directional beam, for communication with one or more serving base station(s). A beam is switched to a non-active beam at the initiation of the dwell time. Signals are received through the switched non-active beam, and samples of the received signals are generated. The samples are stored in a memory. Channel quality is measured using the samples, whereby the dwell time to measure the channel quality is minimized.

A system having a multiple-mirror ring-down cavity with one mirror where light may be input into the cavity and light from the cavity may be detected. A valve may permit light to enter or not to enter the cavity. An amplifier may be connected to a detector for detecting light from the cavity. The amplifier may be off or set at a low gain when light is entering the cavity and be on at a medium or high gain at a time when light is not entering the cavity.

A multi-substrate package assembly having a first substrate, a second substrate and a package, each with a number of bond pads. The package includes a cavity for receiving either or both of the first and second substrates, with a number of bond pads positioned along at least part of the periphery of the cavity. The first substrate and the second substrate are preferably positioned in the cavity of the package, with selected bond pads of the first substrate and second substrate electrically connected to selected bond pads of the package. In some embodiments, the bond pads of the first substrate are only connected to bond pads on one or more sides of the cavity, and the bond pads of the second substrate are only connected to bond pads on one or more of the remaining sides of the cavity. The packaging assembly of the present invention can be used in many applications, including spectrally tunable optical detectors.

Affixing together two articles (16, 12) includes placing a frit preform (200) with an adhesive material on the surface of either article (16, 12). The preform (200) and the articles (16, 12) are heated to cause the frit material to liquify and then cooled to affix together (200a) the two articles (16, 12) at the junction (220) of the two articles (16, 12).

A method for maintaining measurement accuracy of a ring laser gyroscope is disclosed. The method involves periodically measuring a path length control voltage in the ring laser gyroscope over a prescribed temperature range. When a first path length controlled by the path length control voltage deviates at least one wavelength from a nominal path length, the method detects the change in the path length as a mode shift. For each mode shift, the method applies a path length correction to maintain the first path length at a target path length over the prescribed temperature range. The method can apply a correction to a measurement signal output of the ring laser gyroscope by adjusting a calibrated scale factor depending on an actual integer number of wavelengths achieved during a mode shift.
