A contact lens tool kit for placement of a contact lens on an eye is provided. The azidocinnamaldehyde compound is represented by formula: 1wherein R represents a lower alkyl group and Y represents hydrogen or a sulfonate salt group. The display unit includes a switching module which operates in temporal synchrony with the first and second image being generated, such that a user can see the first image only via the first beam path and the second image only via the second beam path. The present invention reduces the number of required digital image data memory buffers required to perform the two functions of bit rotation and row alignment from conventional systems that perform the two functions sequentially and utilize a direct memory access channel to perform the data transfer between integrated circuitry that performs the two functions. The method includes determining, by a source evolved-NodeB, a handover of a User Equipment to a target eNB, obtaining information about content transmitted to the UE from a source cache server connected to the source eNB over a backhaul network, and transmitting the content information to a target eNB. The cured rubber compositions obtained from the elastomeric base compositions herein have good fuel resistance properties.
