Patent CA-2517204-A1 (CA)
Inventor: KUMACHEVA EUGENIA
IPC: C08K9/10
Filed: 2004-03-10
Abstract: The present invention describes a new approach to producing hybrid composite materials with multiscale morphologies. We doped polymer submicrometer spheres with semiconductor or metal (e.g. CdS or Ag, respectively) nanoparticles and used these doped microspheres as the functional building blocks in production of hybrid periodically structured materials. The preparation of hybrid polymer particles included the following stages: (i) synthesis of monodisperse polymer microspheres, (ii) in-situ synthesis of the inorganic nanoparticles either on the surface, or in the bulk of the polymer beads, and (iii) encapsulation of hybrid microspheres with a hydrophobic shell. We demonstrated that by changing the composition of the polymer beads good control could be achieved over the size of the nanoparticles.

Title: Asynchronous jitter reduction technique
Inventor: CASTLEBARY ROBERT ALLEN
IPC: G11C8/18
Filed: 2004-02-10
Abstract: The amount of jitter incurred when reading data written into a FIFO (12) can be reduced by clocking the FIFO with Read Clock pulses at a frequency x fn where x is a whole integer and fn is the frequency at which the memory is clocked to write data. Read Addresses are applied to the FIFO at a frequency on the order of fn to identify successive locations in the memory for reading when the memory is clocked with read clocked pulses to enable reading of samples stored at such successive locations. The duration of at least one successive Read Addresses is altered in response to memory usage status to maintain memory capacity below a prescribed threshold.

Title: Forward/reverse hybrid switching power supply with time-based pulse triggering control
Inventor: KENDRICK GEORGE B
IPC: H01K1/62
Filed: 2006-01-17
Abstract: A phase-control power controller that converts a line voltage to an RMS load voltage includes a fixed phase forward/reverse hybrid phase-control clipping circuit that performs phase-control clipping of a load voltage to provide an RMS load voltage. A conduction angle of the phase-control clipping circuit is defined by a time-based pulse source that triggers conduction in the phase-control clipping circuit independently of line voltage magnitude during time periods that span polarity changes of the load voltage and that are separated by intervals when conduction is not triggered. The phase-control clipping circuit includes a transistor switch whose gate receives positive polarity signals from the time-based pulse source to trigger conduction of the phase-control clipping circuit. The power controller may be in a voltage conversion circuit that converts a line voltage at a lamp terminal to the RMS load voltage usable by a light emitting element of the lamp.

Title: Action rate control system
Inventor: KEENEY MICHAEL D
IPC: F41A25/02
Filed: 2004-10-29
Abstract: An action rate control system for a gas operated firearm that includes an action sleeve and an action rate control cylinder. The action sleeve moves in a rearward direction in response to a volume of combustion gases that are generated during firing of the firearm and diverted from the barrel of the firearm through gas ports. The action rate control cylinder is connected to the action sleeve by a linkage that controls movement and slowing of the action sleeve as it approaches a rear limit for its movement. The resistance force generated by the rate control cylinder is a function of the velocity of the action sleeve during its movement. In another aspect, a gas operated firearm includes a barrel, a bolt assembly, an action system coupled to the bolt assembly, and a rate control cylinder coupled to the action system. The action system includes a sleeve assembly that is driven by a volume of combustion gases that are diverted from the barrel when a round of ammunition is fired. The rate control cylinder controls a terminal velocity of the sleeve assembly being driven by the volume of combustion gases. A resistance force generated by the rate control cylinder is a function of the velocity of the bolt assembly during the bolt assembly's rearward movement. The velocity of the bolt assembly follows a controlled and gradual reduction as the energy load associated with the firing is absorbed by the rate control cylinder.
