Title: Transgenic animals
Inventor: BREMEL ROBERT D
IPC: C07K14/02
Filed: 1999-11-17
Abstract: The present invention provides improved methods and compositions for the generation of transgenic non-human animals. The present invention permits the introduction of exogenous 5nucleic acid sequences into the genome of unfertilized eggs (e.g., pre-maturation oocytes and pre-fertilization oocytes) by microinjection of infectious retrovirus into the perivitelline space of the egg. The methods of the present invention provide an increased efficiency of production of transgenic animals with a reduced rate of generating animals which are mosaic for the presence of the transgene.

Title: Fiber-coupled liquid sample analyzer with liquid flow cell
Inventor: GARRETT MARK H
IPC: G01N21/35
Filed: 2001-08-20
Abstract: A liquid sample analyzer with a flow-through liquid waveguide cell is described. The light source is fiber coupled to a liquid waveguide or light pipe. The light pipe can be remotely located and fiber coupled to the spectrometer so that the light source is thermally isolated making the spectrometer easily thermally stabilized, and the dispersion minimized. The liquid waveguide cell includes a light pipe that has a lower index of refraction than the liquid flowing through the light pipe. Light is input into the liquid waveguide by an optical fiber that is coupled to the liquid waveguide. The optical fiber diameter and the light pipe core diameter and spaceing are selected to provide coupling of all light modes transmitted through the optical fiber into the light pipe. The output light is received by an optical fiber which is arranged to receive all of the light transmitted through the light pipe. The light output from the light pipe is fiber-coupled to the spectrometer with a fiber bundle that is arranged in the form of a slit at the distal end or entrance aperture of the spectrometer.

Title: Method and apparatus for encrypting transmissions in a communication system
Inventor: TIEDEMANN EDWARD G JR
IPC: H04W12/02
Filed: 2000-09-29
Abstract: Method and apparatus for encrypting transmission traffic at separate protocol layers L1 (220), L2 (210), and L3 (200) so that separate encryption elements (204) can be assigned to separate types of transmission traffic (201, 203, 205), which allows the implementation of different levels of encryption according to service requirements. Encryption elements (204) use variable value inputs, called crypto-syncs, along with semi-permanent encryption keys to protect from replay attacks from rogue mobile stations. Since crypto-sync values vary, a method for synchronization and authentificated registration of crypto-syncs is also presented. Crypto-scancs can be built expediently for each different type of traffic frame by using different system resources. In one embodiment, a cyclic redundancy check (CRC) can be used to verify crypto-syncs.
