Abstract: A waveguide polarization recovery system both polarizes the input light energy for use with an LCD imager and converts the polarity of unusable light energy to add to the illumination of the LCD imager. The compact polarization recovery waveguide system generally includes: (1) an input waveguide that provides non-polarized light energy into the system; (2) an output waveguide that receives polarized light energy from the system; (3) a polarized beam splitter that received the light energy from the input waveguide and transmits lights energy of a first polarization type and reflects light energy of a second polarization type, and (4) a wave plate that modifies the polarization of either the transmitted or reflected light energy. The polarization recovery system also generally includes one or more mirrors that are positioned as need to direct the transmitted and the reflected light energy to the output waveguide.

Title: A system for ensuring encrypted communication after handover
Inventor: VIALEN JUKKA
IPC: H04L9/32
Filed: 2001-10-09
Abstract: A fraudulent intruder can eavesdrop on a call by removing information about an encryption algorithm when a multimode mobile station sends an unprotected initial signaling message containing this information over the radio interface to the mobile telecommunications system. The attempt can be prevented in a universal mobile telecommunications system (UMTS) comprising at least two radio access networks providing mobile stations with access to a multimode mobile station, and at least one core network. During connection setup with a first radio access network, the multimode mobile station sends an unprotected initial signaling message that includes information about those encryption algorithms that the multimode mobile station supports when it communicates in a second radio access network.  The first radio access network saves some or all the information of it. Then it composes and sends an integrity-protected message that includes information about the encryption algorithms supported by the multimode mobile station in the second radio access network.
