Abstract: Saturable absorption, polarization, and retroreflection are integrated into a single solid-state optical element (10). The optical element (10) comprises an undoped substrate (14) having front and rear surfaces disposed at a predetermined angle. A dielectric coating (15) is disposed on the rear surface of the substrate (14), and at least one saturable absorber platelet (11) is disposed on the front surface of the substrate (14). The saturable absorbing species used in the platelet(s) (11) are either F2- color-centers in lithium fluoride or Cr4+ dopant ions in one of several suitable host optical materials. Linear polarization of the laser beam (13a) is achieved by orienting the input face of the optical element (10) at Brewster's angle. The dielectric coating (15) (mirror) on the back surface of the optical element (10) provides 100% reflectivity. The optical element (10) is a monolithic, simple to fabricate, easy to align multi-functional element for use in a laser resonator (12). The optical element (10) provides passive Q-switching, discrimination for linear polarization, and laser beam reflection. The mirror is an integral part of the optical element (10), and it is easy to align the integrated polarizer. By aligning the optical element (10) for retroreflection, the Brewster's angle condition is automatically met and optimal polarization discrimination is achieved. The optical element (10) improves the quality and efficiency of lasers in which it is employed. The present invention is easy to align and reduces the number of optical elements in the laser, thereby improving system reliability.

Filed: 1992-09-09
Abstract: There is disclosed a GABAA receptor-chloride ionophore complex (GRC), where GABA represents gamma-aminobutyric acid, having a novel binding site, the GNR, independent of other known sites on the GRC. There is also disclosed a method for screening for agonists of the GNR by forming an expressed GRC by co-expression cDNA  encoding the GRC subunits in cells and determining the ability of a steroid to modulate allosterically benzodiazepine binding to the expressed receptor complex. The figure shows the enhancement of the binding of a benzodiazepine analog to the GRC as a function of the concentration of a steroid modulator which binds to the GNR.

Title: Cordless telephone base unit arranged for operating with multiple portable units
Inventor: BERTOCCI GUIDO
IPC: H04M1/72505
Filed: 1995-10-30
Abstract: A cordless telephone system includes an arrangement wherein multiple portable units operate with a common base unit using the same security code without conflict or confusion. When a portable unit attempts to establish a radio link with the base unit, for example, this originating portable unit generates a random number which is retained by this unit and also transmitted  to the base unit. This random number is substituted for the common stored security code, then shared by the base unit and all of the portable units, for creating a temporary unique security code that is known only to the base unit and the originating portable unit. Interference from other portable units attempting  to gain access to the base unit while the originating portable unit is actively communicating with the base unit is thereby advantageously prevented.

Patent CA-2166253-A1 (CA)
Inventor: BLAINEY ROBERT JAMES
IPC: G06F9/45
Filed: 1995-12-28
Abstract: A method for partitioning programs into multi-procedure modules for efficient compilation.  During interprocedural analysis, a weighted callgraph of the program is constructed in which weights on nodes represent code size of each procedure and weights on edges between the nodes represent execution counts between procedures. A coloured interference graph is built from the analysis information, and is used to induce weighted sub-graphs of the callgraph containing no interferences between procedures in each sub-graph. The procedures from a single sub-graph are combined into one or more modules; procedures with the highest weighted edges between them are combined in a module first until the cumulative node weight of the module reaches a preset limit on memory size.

Title: No-vent dry kiln
Inventor: GOODWIN TOM E III
IPC: F26B21/08
Filed: 1996-01-16
Abstract: A no-vent dry kiln for drying wood products such as lumber. The kiln has a dehumidification unit to remove excess moisture from the air utilized as the drying media. The dry bulb and wet bulb temperatures of the air within the kiln en- closure are precisely monitored to control the conditions of the atmosphere within the kiln enclosure. The kiln has a de- humidification unit to remove excess moisture from the air and to retain the sensible heat of the air stream passing through the dehumidification unit. The air stream, under a controlled flow rate passes through a first coil which removes the sen- sible heat from the air stream to lower the temperature of the air stream to at or below its saturation temperature. the heat removed by the first coil is transferred to a third coil downstream. A second coil downstream from the first coil lowers the temperature of the air stream well below the dew point causing the condensing of moisture. The condensed mois- ture is removed by a condensate removal system. The dehumid- ified air the passes through the third coil where the heat previously removed by the first coil is reintroduced into the air stream, adding heat if necessary to bring the air stream up to the desired dry bulb temperature. The air stream is the admixed with the drying air within the kiln enclosure. Both the dry bulb and wet bulb temperatures of the air are precisely controlled to provide a desired drying schedule.
