Title: Unactivated oocytes as cytoplast recipients for nuclear transfer
Inventor: CAMPBELL KEITH HENRY STOCKMAN
IPC: A61K35/54
Filed: 1996-08-30
Abstract: A method of reconstituting an animal embryo involves transferring a diploid nucleus into an oocyte which is arrested in the metaphase of the second meiotic division. The oocyte is not activated at the time of transfer, so that the donor nucleus is kept exposed to the recipient cytoplasm for a period of time. The diploid nucleus can be donated by a cell in either the G0 or G1 phase of the cell cycle at the time of transfer. Subsequently, the reconstituted embryo is activated. Correct ploidy is maintained during activation, for example, by incubating the reconstituted embryo in the presence of a microtubule inhibitor much as nocodazole. The reconstituted embryo may then give rise to one or more live animal births. The invention is useful in the production of transgenic animals as well as non-transgenics of high genetic merit.

Title: Channel estimation in mobile communications networks
Inventor: MOHEBBI BEHZAD
IPC: H04L25/02
Filed: 1999-08-10
Abstract: In a cellular mobile communications network a group of mobile stations (20) transmit respective predetermined transmit signals to a base station (10) via different respective uplink channels such that those signals are received substantially simultaneously by the base station. The predetermined transmit signals all embody the same predetermined sequence of symbols but the embodied sequences are shifted in phase one from the next in the different signals by predetermined amounts. The base station includes a channel impulse response estimating unit (14) which employs the predetermined transmit signals as received by the base station and the predetermined sequence to produce estimates (UPEST<SB>1</SB>   UPEST<SB>n</SB>) of the respective channel impulse responses of the different uplink channels. An estimation control unit (16) controls the operation of the channel impulse response estimating unit (14) such that a range of delay time values (e.g. W<SB>2</SB>) covered by the estimate produced for at least one channel is made greater than a range of delay time values (e.g. W<SB>1</SB>) covered by the estimate produced for another of the said channels. The range (W) for each channel may be set in dependence upon an expected maximum delay time for the channel concerned. In this way, more accurate estimates can be produced for "longer" channels and unnecessary calculations of insignificant elements of the estimates for "short" channels can be avoided. In another embodiment the ranges are set equally but dynamically in dependence upon the downlink-channel maximum delay times of the group measured in the mobile stations and reported back to the base station.
