Inventor: LIVINGSTON PETER M
IPC: G01S17/86
Filed: 1998-07-22
Abstract: An imaging self-referencing target tracker  (10)  for a laser weapon (12).  The weapon generates a first beam of radiation (14)  that engages a target  (16)  to form a beam hit spot  (20) thereon.    In  a  first  embodiment,  a  target  illuminator  (22) (variant 1) illuminates the target with a second beam of radiation (23a).   An optics subsystem  (30)  receives and separately images the first and second beams  (23b, 24) of radiation.   In a second embodiment, a blocking filter (40)  is implemented rather than an illumination  laser  to  pass  only  radiation  at   the  target wavelength,  thereby ensuring that the first and second beams of radiation are separately imaged.  A controller (32)  is programmed to steer the first and second beams of radiation to the desired target aim point  (18)  in response to information from the imaged first and second beams of radiation.   The tracker of the present invention tracks the laser hit spot relative to the actual target image in a closed loop manner,  thereby increasing the probability of accurate target engagement and resulting in a target kill.

Title: Purified proteins, recombinant dna sequences and processes for controlling the ripening of coffee plants
Inventor: MOISYADI ISTEFO
IPC: C12N15/11
Filed: 1997-08-11
Abstract: The invention provides purified proteins, DNA  sequences that code on expression therefore and recombinant DNA molecules, including hosts transformed therewith for transforming coffee plants to suppress the expression of enzymes necessary for ethylene synthesis. The DNA sequences and recombinant DNA molecules are characterized in that they code on expression for the enzymes ACC synthase or ACC  oxidase that are elements of the pathway for ethylene biosynthesis in coffee plants. Coffee plants are transformed with vectors containing ACC synthase and/or with ACC oxidase DNA sequences that code on expression for the respective mRNA  that is antisense to the mRNA for ACC synthase and/or ACC  oxidase. The resulting antisense mRNA binds to the respective ACC synthase and/or ACC oxidase mRNA, thereby inactivating the mRNA encoding one or more enzymes in the pathway for ethylene synthesis. The described DNA sequences can also be used to block synthesis of ACC synthase or ACC  oxidase using co-suppression. The result in either event is that the transformed plants are incapable of synthesizing ethylene, though other aspects of their metabolism is not affected.

At least one of the ports is sealed by an adjustable non-return valve (36) acting as an adjustable hydraulic brake operable to prevent oil discharge unless the pressure exerted on the oil by the piston is such that it exceeds the most extreme of the expected use conditions of the vehicle.
Patent CA-2264350-A1 (CA)
Title: Carrier recovery system
Inventor: JIANG HONG
IPC: H04L27/00
Filed: 1999-03-04
Abstract: A digital carrier recovery system includes at least two modes of operation, namely, an acquisition mode and a tracking mode. The bandwidth of the carrier recovery loop filter is different for the acquisition mode and the tracking mode. In the acquisition mode, the digital phase-locked loop seeks and locks to the long term frequency offset of the received carrier signal. In the tracking mode, the digital phase-locked loop tracks the instantaneous variations in the carrier phase.  Switching between the acquisition mode and the tracking mode is realized digitally, and includes programmable hysteresis, resulting in optimal performance in the presence of signals having high levels of phase noise (jitter). More specifically, the carrier recovery loop filter "locks" to the pilot signal of an incoming signal, e.g., a vestigial side band (VSB) video signal, by employing a so-called digital vector tracking phase-locked loop that demodulates the VSB signal. The digital vector tracking phase-locked loop includes a complex filter, i. e., a so-called vector tracking filter, that very quickly locks to the pilot signal of the passband VSB signal and once locked to the pilot signal, switches to the tracking mode that provides significantly better tracking of phase noise. The demodulation is achieved by employing a complex multiplication of the incoming signal with a complex exponential sequence to obtain an in-phase (I-phase) component and a quadrature-phase (Q-phase) component. The complex exponential sequence is generated, in one embodiment, by employing a SIN/COS look up table that is driven by a phase difference signal generated by the digital vector tracking phase-locked loop. A residual direct current (dc) component in the I-phase component caused by the pilot signal is removed, resulting in a baseband I/Q signal. A technical advantage of this carrier recovery invention is that the bandwidth of the phase-locked loop filter can be different for the acquisition mode and the tracking mode. This allows for optimal performance in both the acquisition and tracking modes of operation.

Title: Transport architecture and network elements
Inventor: LIVERMORE FREDERICK CALDWELL
IPC: H04L12/56
Filed: 1997-11-12
Abstract: A novel transport architecture and network elements use nodes in a ring or virtual ring configuration. Information is exchanged among the nodes in a continuous series of containers carried in a superframe. A container is assigned to a destination node and is divided into partitions which are allocated for source nodes. Therefore, when a container destined to a particular destination node arrives at a node and if this node has information to send to the destination node, it fills the allocated partition within the container with information destined to the destination node. The sizes of the superframe, containers and partitions are all variable dynamically or statically.
