Ayoub Rashtchian - Gaithersburg MD

Assignee:

Invitrogen Corporation - Carlsbad CA

International Classification:

C12Q 168

US Classification:

435 912, 435 6, 435 71, 435 911, 435 9151, 536 221, 536 231, 536 243, 536 2431, 536 2432, 536 2433

Abstract:

The present invention is directed to compositions and methods useful for the amplification of nucleic acid molecules by reverse transcriptase-polymerase chain reaction (RT-PCR). Specifically, the invention provides compositions and methods for the amplification of nucleic acid molecules in a simplified one- or two-step RT-PCR procedure using combinations of reverse transcriptase and thermostable DNA polymerase enzymes in conjunction with sulfur-containing molecules or acetate-containing molecules (or combinations of such sulfur-containing molecules and acetate-containing molecules), and optionally bovine serum albumin. The invention thus facilitates the rapid and efficient amplification of nucleic acid molecules and the detection and quantitation of RNA molecules. The invention also is useful in the rapid production and amplification of cDNAs which may be used for a variety of industrial, medical and forensic purposes.

Abstract:

The present invention is in the fields of molecular and cellular biology. The invention is generally related to reverse transcriptase enzymes and methods for the reverse transcription of nucleic acid molecules, especially messenger RNA molecules. Specifically, the invention relates to reverse transcriptase enzymes which have been mutated or modified to increase thermostability, decrease terminal deoxynucleotidyl transferase activity, and/or increase fidelity, and to methods of producing, amplifying or sequencing nucleic acid molecules (particularly cDNA molecules) using these reverse transcriptase enzymes or compositions. The invention also relates to nucleic acid molecules produced by these methods and to the use of such nucleic acid molecules to produce desired polypeptides. The invention also concerns kits comprising such enzymes or compositions.

Abstract:

A method of generating a behavior of a robot includes measuring input data associated with a plurality of user responses, applying an algorithm to the input data of the plurality of user responses to generate a plurality of user character classes, storing the plurality of user character classes in a database, classifying an individual user into a selected one of the plurality of user character classes by generating user preference data, selecting a robot behavior based on the selected user character class, and controlling the actions of the robot in accordance with the selected robot behavior during a user-robot interaction session. The selected user character class and the user preference data are based at least in part on input data associated with the individual user.

Assignee:

Samsung Electronics Co., Ltd. - Suwon

International Classification:

H04J3/06

US Classification:

370216

Abstract:

In a clock system having active and standby clocks for synchronizing cell data flow in a data system, and for preventing cell data loss during active to standby clock switching, a prevent circuit maintains the active clock cycle signal during the active/standby clock switching to ensure the proper setup time before the active clock is disabled. The prior standby clock will become active during the maintenance period, thereby providing the proper setup time before and after switching, permitting system redundancy without loss of data.
