Abstract: The thickness of a silicon wafer (3) within a processing vacuum enclosure (1) is measured or monitored by an optical apparatus (50) via a window (4). The optical apparatus (5) comprises a laser which is tuneable across a range of wavelengths while maintaining a narrow bandwidth. The optical apparatus (5) also includes a detector receiving reflected light. The wavelength variation produces interference effects which are used, by examination of the detector output, to give a measure of thickness or other parameters.

Abstract: An apparatus and method provide MAC logic enabling the use of two or more reverse link rate controls at the same time in one or more sectors of a radio base station. That enables the base station to control reverse link loading via reverse link rate control, while assigning mobile stations to the type of reverse link rate control best suited to their needs. For example, the base station MAC logic may implement both a common rate controller that generates per-sector rate control commands, and a dedicated rate controller that generates per-user rate control commands and assign mobile stations having relatively lax reverse link service needs to the common rate controller, while assigning mobile stations having more demanding reverse link service requirements to the dedicated rate control. More than two rate controls can be implemented, and exemplary choices include per-user, per-sector, per-group, and scheduled rate control in any combination.

Abstract: A method and apparatus for link supervision determines whether a link signal is present or absent by measuring received energy for that signal. If the measured energy for the signal does not meet a defined energy threshold according to defined evaluation criteria, such as a sufficiency metric, the signal is deemed absent. Applied to wireless communication networks, such supervision may be used to suspend or terminate transmission responsive to detecting the link signal's absence. In an exemplary embodiment for 1×EV-DV (cdma2000 Revision C) wireless networks, a mobile station selectively performs forward link supervision based on measuring the bit energy of power control bits received by the mobile on a dedicated power control sub-channel. If a fundicated channel is assigned to the mobile station, it may perform forward link supervision based on Frame Error Rate (FER) estimations for data received on the fundicated channel rather than the energy-based approach.
