Filed: 1993-06-15
Abstract: The present invention provides a method and system in a data processing system,  having a multitasking operating system which  includes  a  plurality  of  processes,  for  providing communication between objects executing within the processes in the multitasking operating system, the method and system includes  registering  an  object  within  a  communications manager  in  response  to  a  launching  of  the  object.  The communications manager monitors all objects registered with the  communications  manager  within  the  plurality  of processes.  A determination of whether a  first object is registered is made utilizing the communications manager, in response to receiving a request from a second object to send a message to the first object. Automatic initiation of the launching the first object within the processes is performed if  the  first  object  is unregistered  utilizing  the communications manager. Next, the first process containing the first object is bound to the second process containing the  second  object,  wherein  a  communications  path  is established between the first process and the second of the process. The message is sent to the first object from the second  object  via  the  established  communications  path between the two processes, wherein communication between the first  object  and  the  second  object  is  automatically established.

Filed: 1993-07-19
Abstract: A  wavelength stabilization apparatus and method for a superfluorescent source comprising a SFS (superfluorescent source) comprising a fiber with a core doped with lazing material.  The SFS source produces SFS light with an SFS wavelength when pumped with pump light from a pump light source having a pump light wavelength.  An output controller responds to a sample of the SFS light and operates to maximize the power of the sample of SFS light by automatically adjusting the pump light wavelength.  The output controller also has a pump power controller responsive to a sample of the pump light from the pump light source for stabilizing the output power of the sample of the pump light with respect to a predetermined reference output power level.

Patent CA-2117931-A1 (CA)
Title: Adaptive Microphone Array
Inventor: CEZANNE JUERGEN
IPC: H04R3/00
Filed: 1994-10-12
Abstract: The present invention is directed to a method of apparatus of enhancing the signal-to-noise ratio of a microphone array. The array includes a plurality of microphones and has a directivity pattern which is adjustable based on one or more parameters. The parameters are evaluated so as to realize an angular orientation of a directivity pattern null. This angular orientation of the directivity pattern null reduces microphone array output signal level. Parameter evaluation is performed under a constraint that the null be located within a predetermined region of space. Advantageously, the predetermined region of space is a region from which undesired acoustic energy is expected to impinge upon the array, and the angular orientation of a directivity pattern null substantially aligns with the angular orientation of undesired acoustic energy. Output signals of the array microphones are modified based on one or more evaluated parameters. An array output signal is formed based on modified and unmodified microphone output signals. The evaluation of parameters, the modification of output signals, and the formation of an array output signal may be performed a plurality of times to obtain an adaptive array response. Embodiments of the invention include those having a plurality of directivity patterns corresponding to a plurality of frequency subbands. Illustratively, the array may comprise a plurality of cardioid sensors.

Title: A method of preparing an emulsion- or asphalt-concrete for use as a road material
Inventor: HOVE LEO
IPC: E01C19/10
Filed: 1992-10-30
Abstract: ABSTRACT OF THE DISCLOSURE      In the production of emulsion concrete to be laid out as a road material it is customary that the applied stone fractions are mixed together with a binder, which is a bitumen emulsion based on a relatively low viscid bitumen, as the material would otherwise be very difficult to shape by the laying operation.  According to the invention the coarse stone fraction is pretreated with a rapid breaking emulsion based on high viscid bitumen, and only thereafter the fine stone fraction with low viscid binder is added.  Thereby it is possible to maintain a good shapeability of the material and yet obtain a significantly improved bonding of or in the laid out material.

Further air flow dries the encapsulated space.  Desired coatings, for example, rust inhibitor or epoxies, are introduced into the encapsulated space through the lower valve and the displaced air, excess coatings and chemical by-products are vented and recovered for disposal through the upper valve.  The temperature inside the encapsulated space is also controlled.

Title: Low amperage electronic milk level detector
Inventor: MONTREUIL MICHEL
IPC: G01F23/24
Filed: 1995-03-02
Abstract: An electric device is adapted to detect the  level  of  liquid  in a  receptacle  in view of controlling this level of liquid.  The receptacle is installed on a milking system for accumulating either milk drawn through piping of the milking system from at least an animal being milked or water during a washing operation of that piping.   At least two electrodes are mounted in the receptacle.  When the level of liquid reaches a predetermined level, the two electrodes  are  electrically  interconnected  and  a detecting current flows through the liquid between the two electrodes.  The detecting current has a frequency situated within a frequency range substantially higher than 60 Hz, in which the animal being milked has a lower sensitivity to electric current.   The higher frequency of the detecting current also reduce  a capacitive impedance formed by the two electrodes and the water during the washing operation of the milking system to thereby enable a low-intensity detecting current to be established both in milk and water with low-amplitude voltages applied to the electrodes.
