Title: Preparation of co-and terpolymers of p-hydroxystyrene and alkyl acrylates
Inventor: SHEEHAN MICHAEL T
IPC: G03F7/004
Filed: 2001-06-14
Abstract: A novel one-pot cost efficient process for the preparation of co- and terpolymers of p-hydroxystyrene or substituted p-hydroxystyrene and alkyl acrylates is disclosed and claimed. The process involves polymerization of esters of p-hydroxystyrene (or its substituted analogs), alkyl acrylate monomers and one or more of ethylenically unsaturated monomers in an alcoholic solvent in the presence of a free radical initiator. Subsequent hydrolysis of so formed polymer under transesterification conditions using catalytic amounts of base catalyst results in co- and/or terpolymers of p-hydroxystyrene without cleavage of the alkyl ester in the acrylate repeat unit. Preferred embodiments include copolymer of p-hydroxytyrene and tert-butyl acrylate and terpolymer of p-hydroxystyrene, tert-butyl acrylate and styrene. These polymers have a wide variety of applications including as photoresists in microelectronics industry.

Title: Power saving in communication terminals
Inventor: MAYRENCH RONEN
IPC: H04W52/02
Filed: 2004-07-21
Abstract: A communications terminal using interleaving may be awakened at certain times. The paging message determines whether the terminal will remain awake or it can return to sleep. The amount of time that the communications terminal is awakened may be reduced by determining whether it is necessary to demodulate all of the available time slots. In many cases, it may be possible, based on the environment in which terminal finds itself and the quality of the signals it receives, to obtain the necessary information without demodulating symbols from all the time slots in which symbols of the message are transmitted. As a result the period to receive the paging message may be reduced and the power consumption may likewise be reduced.

Patent HK-1097600-A1 (HK)
Title: Method and apparatus for selectively compacting test responses
Inventor: RAJSKI JANUSZ
IPC: H01L21/822
Filed: 2003-01-22
Abstract: A method and apparatus to compact test responses containing unknown values or multiple fault effects in a deterministic test environment. The proposed selective compactor employs a linear compactor with selection circuitry for selectively passing test responses to the compactor. In one embodiment, gating logic is controlled by a control register, a decoder, and flag registers. This circuitry, in conjunction with any conventional parallel test-response compaction scheme, allows control circuitry to selectively enable serial outputs of desired scan chains to be fed into a parallel compactor at a particular clock rate. A first flag register determines whether all, or only some, scan chain outputs are enabled and fed through the compactor. A second flag register determines if the scan chain selected by the selector register is enabled and all other scan chains are disabled, or the selected scan chain is disabled and all other scan chains are enabled. Other embodiments allow selective masking of a variable number of scan chain outputs.
