Title: Method and apparatus for materials analysis by enhanced laser induced plasma spectroscopy
Inventor: ST-ONGE LOUIS
IPC: G01N21/71
Filed: 2000-01-17
Abstract: A method and apparatus is disclosed for enhanced laser-induced plasma spectroscopic analysis of unknown heterogeneous materials. The apparatus has high power pulsed lasers with their beams focused on the material, typically two collinear lasers providing two pulses in the ultraviolet and in the near infrared spectral area. The first laser pulse vaporizes a small volume at the surface of the material and produces a plasma which is subsequently enhanced by the second laser pulse. The optical emission of the plasma is analyzed with a collinear optical spectrometer. The pulsed spectrum is detected by a gated photodiode array detector or by an array of photomultipliers each individually positioned to detect a line emission representative of a given element present in the material. The combination of the two laser pulses, appropriately synchronized, provides a plasma emission that is significantly stronger than a single laser pulse of the combined energy of the two pulses.

Patent CA-2300889-A1 (CA)
Title: A device and a method for switching data frames
Inventor: MALMQVIST FREDERIK
IPC: H04Q11/08
Filed: 1998-08-20
Abstract: The invention relates to a switching device for switching input data frames (IDF) from a plurality of N input lines (i1, i2, ... i n, i N) to output data frames (ODF) on a plurality of M output lines (o1, o2, ... o n, o M). The switching device contains a number K of switch pattern units, each containing a specific switch pattern. A number K of frame store memories (FSM j) each store all input data frames from all input lines in every frame period. Each frame store memory is used for selecting bits to a sub-group of M/K output lines. The parallelly working units (u1, u2, ... u K) each sequentially select a plurality of M/K bits from the stored input lines. The parallelly working units (u1, u2, ... u K) each sequentially select a plurality of M/K bits from the stored input data frames and simultaneously assign the selected bits to the output data frames on the respective sub-group of output lines. The selection and assigning of bits in each unit is performed at a M/K times higher clock rate than the bit rate on the input data lines. Thus, a bit-orientated reading of input data frames and writing of output data frames is achieved which allows a flexible switching of full rate as well as sub-rate input PCM data frames.

Patent CA-2302113-A1 (CA)
Title: Animal trap
Inventor: DECORBY GEORGE
IPC: A01M23/20
Filed: 2000-03-27
Abstract: Humane, live animal traps are usually difficult to set and/or blend into an environment which the particular animal being trapped has become accustomed to. The present device consists of box, cage-like device which is hinged on the base. All that portion shave the base where lifted open leaves the animal with a spacious non threatening entry. The bottom of the trap,(the base) has welded to it solidly, a vertical post that extends up from in between the hinges to the top portion of the trap. At the top of this post a hinged latch is attached which will serve two functions with the primary function of engaging with an adjustable pin situated in a block welded solidly to the top portion of the trap. When the trap is opened to engage the latch and the pin, the trap will remain open. The method of disengaging the latch and the pin consists of a lever that is situated near to the pin and operated in such a way as to lift the latch up and over the pin when the lever that extends down to within reach of the animal is moved,  in the present traps them are two types of levers that can be used. The one lever incorporated now into the trap activates the trigger by a push or pull action from one direction.  A second fever that can be incorporated into the same trap world activate the trigger by a push or pull action from any direction. The first lever or the second lever can both be used in the trap to accommodate different applications or animals. Once the trigger has been activated the uniquely constructed top portion of the trap utilizes and maximizes the benifits of gravity to close down over the animals to rest on the base. Now the latch performs it's secondary function which involves dropping down to lock and maintain the trap in a closed position. In maintaining the ingenuity and integrity of that for which this trap is intended, it must be pointed out that if by some remote chance a second animal has not completely entered the trap when it is activated to be closed by the first, the latch will not perform it's purpose until this animal is completely in or out of captivity.  The trap is not intended to hurt, maim or kill an animal by being squeezed or strangled between the walls of the top part of the cage and the base.

Patent CA-2310500-A1 (CA)
Inventor: SHIRAISHI KENICHI
IPC: H04L1/20
Filed: 1998-11-19
Abstract: A synchronization acquiring circuit for stably acquiring frame synchronization without pseudo-synchronization lock during reception at a low C/N ratio. The C/N ratio of a transmission path is determined by a C/N ratio determining circuit (9) and a correlation detection reference value is determined on the basis of the determined C/N ratio. The synchronization pattern of a received frame is detected by a frame synchronization detecting circuit (2). The bits of the synchronization pattern of the received frame are compared with those of a frame synchronization pattern on the transmission side by a frame synchronizing circuit (5) to determine the number of coincided bits. The frame synchronization is regarded as detected when the determined number of bits of each frame is equal to or larger than the correlation detection value.  When a reception signal phase vector distribution determining circuit (8) detects that a distribution vector of signal point positioning of a TMCC interval is normal and a burst symbol signal error measuring/judging circuit (10) judges that the distribution vector of a burst symbol signal is normal, synchronization is regarded as established.
