Abstract: A method of performing geometrical measurements of remote objects includes performing a laser sweep of a measurement object with a handheld sensor device including a distance measurement unit and an inertial measurement unit. The method includes activating the distance measurement unit to perform a plurality of distance measurements during the laser sweep, and activating the inertial measurement unit to perform an inertial measurement in association with each of the distance measurements. A processor is used to process the distance measurements with reference to the associated inertial measurements to determine a geometric characteristic of the measurement object.

Abstract: Interference cancellation is performed in a communication system. A signal associated with the users is received to produce a received signal. A set of regeneration factors associated with the users is determined based on the received signal. A frequency range associated with a first user from the users has at least a portion overlapping with at least a portion of a frequency range associated with a second user from the users. A time range associated with the first user from the users has at least a portion overlapping with at least a portion of a time range associated with the second user from the users. A regenerated signal associated with each user from the users is modified based on the determined regenerated factor associated with that user to produce a modified regenerated signal for each user.

Abstract: An electrode is provided for a spark plug made of a base material and at least one additive material situated in the base material in a dispersedly distributed manner, which is intercalated in the base material, and is a metal oxide, and is characterized by a negative enthalpy of formation greater than 800 kJ/mol O2. The base material is an Au based or an Rh based material or is pure Au or Rh, the proportion of the additive material amounting to between 5 vol. % and 50 vol. %. Alternatively, Pt-based materials or pure Pt are provided as the base material, the proportion of the additive material at average particle diameters of the additive material between 5 ?m and 20 ?m amounting to between 21 vol. % and 50 vol.

Abstract: A first downlink transmission beam and a second downlink transmission beam is determined based on a received user-derived signal. The first downlink transmission beam is substantially uncorrelated with the second downlink transmission beam. The first downlink transmission beam is associated with a portion within a first sector. The second downlink transmission beam is associated with a portion within a second sector. A first signal is diversity encoded to produce a first diversity-encoded signal. A second signal is diversity encoded to produce a second diversity-encoded signal. The first diversity-encoded signal is sent over the first downlink transmission beam. The second diversity-encoded signal is sent over the second downlink transmission beam.

Abstract: Method and apparatus for high resolution tracking via mono-pulse beam-forming in a communication system in which the capacity and range of mobile or fixed wireless communication base stations are improved by implementing a single or multiple antenna beam per signal path. Adaptive beam-forming based on up-link direction-of arrival estimation can be performed without using the above-mentioned computationally intensive techniques.
