摘要： Techniques for optimizing the sensitivity of spectroscopic measurement techniques with respect to certain profile variables by selecting desired measurement angles since the measurement sensitivity to each variable depends, at least in part, on the measurement angles of an incident beam. The selected desired set of measurement angles includes both an azimuth angle and a polar angle. Optimizing the sensitivity of spectroscopic measurement techniques can also reduce or eliminates measurement correlation among variable to be measured.

摘要： A polarized sample beam of broadband radiation is focused onto the surface of a sample and the radiation modified by the sample is collected by means of a mirror system in different planes of incidence. The sample beam focused to the sample has a multitude of polarization states. The modified radiation is analyzed with respect to a polarization plane to provide a polarimetric spectrum. Thickness and refractive information may then be derived from the spectrum. Preferably the polarization of the sample beam is altered only by the focusing and the sample, and the analyzing is done with respect to a fixed polarization plane. In the preferred embodiment, the focusing of the sample beam and the collection of the modified radiation are repeated employing two different apertures to detect the presence or absence of a birefringence axis in the sample. In another preferred embodiment, the above-described technique may be combined with ellipsometry for determining the thicknesses and refractive indices of thin films.

摘要： Disclosed are apparatuses, methods and computer program instructions which receive or detect an in-device coexistence interference condition change in a user equipment equipped with a plurality of transceivers, send an indication of the in-device coexistence interference condition change to an access point and receive a media access control element configured for muting/unmuting at least one of a plurality of transceivers from the access point. The condition of in-device coexistence interference relates to interference among transceivers such as a long term evolution advanced transceiver and a Bluetooth transceiver in the same user equipment.

摘要： To find a D2D channel, by example a shared channel for offload traffic from an allocated D2D channel, a cellular network access node sends a configuration message with parameters (e.g., sensing time, frequency band, sensing mechanism, cyclic shift) for a D2D device to sense spectrum. From results of this spectrum sensing is decided whether to utilize a frequency band, sensed according to the parameters, for D2D communications. In an embodiment the network selects a subframe configuration to set the sensing time, in which different subframe configurations have different-length guard periods which is the sensing time. In embodiments a first sensing is within a guard period and represents coarse sensing results and if those are not sufficient the network configures a longer sensing time (e.g., spanning multiple subframes) for finer sensing results. The network or alternatively the D2D device decides whether to use the sensed frequency band for offload traffic.
