Patent CA-2118467-A1 (CA)
Title: Portable fire fighting tool
Inventor: ESPOSITO JOHN
IPC: A62C3/07
Filed: 1994-10-19
Abstract: A portable fire fighting tool that is connectable to a portable fire extinguisher is described. This tool comprises a penetrating head with a removable, sharp cutting element thereon and wherein the penetrating head is preferable connected at 90° to a linear, hollow handle. At the opposite end of the handle a quick connect device may be used to connect a portable fire extinguisher and the handle together. This tool is especially useful in fighting an automobile or truck engine or trunk compartment fire when the automobile or truck is locked preventing entry into the engine compartment or the trunk. By forcing the penetrating head down and through the sheet metal of the engine or trunk compartment, the cutting element cuts through the sheet metal. When the fire extinguisher is discharged, the fire extinguishing agent (e.g. foam, water, dry chemical, Halon ? or CO2) flows down over the cutting element in an umbrella-like fashion extinguishing the fire without doing further damage to the automobile or truck. This tool will allow a faster response to and control of a the fire situation thus limiting damage which normally takes place when force is used to gain access to a locked engine or trunk compartment. The element of this invention saves time in fighting an engine or trunk compartment fire and provides the ultimate in safety for the fire fighter.

Title: Method and apparatus for calibrating and improving linearity of system for scanning moving objects
Inventor: SCHWARTZ NIRA
IPC: G02B27/00
Filed: 1992-10-30
Abstract: A method for calibrating and improving linearity of system for scanning moving objects. A type of scanning system, a set of parameters to define the scanning system are selected. A set of initial values for some of the parameters are also selected and Mathematical equations are derived which describe physical movements of the scanning and relationships between the parameters. The equations are solved to find values for the parameters with which the objects are scanned by an incident light with linearity and a predetermined accuracy. The parameters of the scanning system are then set to the values obtained by solving the equations. The system itself consists of the rotating polygon (34) and a rotating carousel (42) having predetermined axes of their rotation. The polygon (34) has a plurality of facets (46) which are symmetric with respect to the polygon's axis of rotation. The carousel supports objects, such as bottles (36, 37...41) which also may have spinning motions. The system may operate in a reading mode when objects areilluminated by an incident light beam which is reflected and is directed to a processing unit, or in a writing mode when the surfaces of the objects are treated, e.g., by a laser beam for engraving marks while the objects are moved by the carousel (42) and spin around their own axes.

Filed: 1993-10-14
Abstract: A method and apparatus for applying optical or other thermal energy to tissue using a clamp (12). The energy is supplied at a frequency which biologically welds or fuses tissue. A material (30) that is transmissive to the energy treatment frequency is embedded in one or more jaws (18, 20) of the clamp (12) and engages the tissue during the tissue fusion process. The transmissive material (30) has a thickness selected to insure that the energy source is spaced at the proper distance from the tissue to that the tissue receives the proper amount of energy for sealing. The transmissive material (30) holds the tissue in the jaw to maintain the edges of the tissue in tight approximation. The energy may be coupled to the clamp by one or more optical fibers (54). These fibers (54) are recessed in or placed adjacent to the jaw at a specified distance from the surface of the transmissive material (30) and directs treatment energy through the transmissive material (30) to weld the edges of the tissue together.

Title: Packet network transit delay measurement system
Inventor: SHUR DAVID H
IPC: H04L12/26
Filed: 1995-10-16
Abstract: A system for analyzing and estimating average transit delay and high percentiles of delay in a packet network. The system utilizes detailed packet switch measurements that are normally stored in a network database for maintenance and engineering purposes. The system randomly selects source and destination points and samples the stored maintenance measurements for network circuit elements located between the randomly selected source and destination points. These sampled measurements are transmitted to the system processor via electronic mail and the system generates a single server queuing model to determine average and variance of delay for each component.  A network-of-queues model is then constructed to determine the end-to-end average delay and end-to-end variance of delay. An Erlang probability distribution is then fit to these end-to-end values to provide statistics of packet transit delay in the packet network.
