Title: A brassica sp. polygalacturonase gene promoter
Inventor: ROBERT LAURIAN
IPC: C12N9/24
Filed: 1995-12-21
Granted: 2004-06-01
Abstract: A Brassica sp. genomic clone containing a polygalacturonase gene promoter was isolated. This promoter directs high levels of transcription in the pollen. When the promoter was fused with the GUS gene and introduced into B. napus by Agrobacterium mediated transformation, this promoter controlled GUS expression in microspores and pollen in transgenic B, napus plants. Expression occurred between the late uninucleate microspore stage and the mature pollen grain stage.      GUS activity was also identified in tapetal tissue at the binucleate microspore stage. There was no GUS expression in other tissues such as root, stem, leaf, sepal, petal or pistil. This promoter will be useful for the temporal and spatial control of endogenous gene expression in plants.

Title: Appliance wash cycle selection method and apparatus
Inventor: COOPER RANDALL L
IPC: D06F34/22
Filed: 1996-01-03
Granted: 2004-08-03
Abstract: A method of selecting a washing cycle for an intelligent appliance uses several factors to make a cycle selection. The first factor is a combination of the water turbidity, conductivity and temperature as well as the wash arm speed. The other factors are the average of previously selected cycles, the number of times the appliance door has been opened and the time between wash cycles. The appliance also allows the user to bump up the selected cycle to a higher cycle if the user is unsatisfied with the performance of the appliance. If a failure has occurred with any of the sensors or in the communications routine, the appliance selects the average of previously selected cycles as the wash cycle.

Abstract: A poke-through electrical connector includes an elongate, generally tubular housing member and at least one retaining clip for securing the connector in an interfloor passage. The retaining clip includes a transverse flexure portion and at least one anchor point dimensioned and angled from the flexure portion for substantially radially-directed engagement with the wall of the interfloor passage.

Patent CA-2210096-C (CA)
Inventor: HABBERSETT JOHN I
IPC: E05F3/18
Filed: 1997-07-09
Granted: 2000-09-12
Abstract: A coupling between a twisted rod and a torsion spring of a spiral counterbalance is found to be subject to deformation against the twisted rod from compressive force of the grip of the terminal convolutions of the torsion spring. This problem is solved by using a metal cylinder in the rotation transmission sleeve of the coupling to resist the compressive force and prevent deformation so that the twisted rod can move freely within the coupling. This solution also allows the use of a stronger torsion spring to exert a larger counterbalance force.
Patent CA-2210123-C (CA)
Inventor: LATRASSE CHRISTINE
IPC: G01J3/28

Granted: 2001-04-17
Abstract: Arrangements are disclosed for the automatic absolute frequency calibration of a variable frequency optical source using an optical filter,  such as gas cell   or   a   calibrated   interferometer,   providing resonances at known frequencies in the tuning range of the source.   The above calibration is performed by a control  unit  which  has  a  knowledge  of  the  known transmission pattern of the optical filter.  This unit scans  the  frequency  of  the optical  source  via  a frequency control signal over a frequency range and measures the optical intensity of the optical source output light after it has passed through the optical filter.    The  measured  transmission  and  frequency control  signal  values  are  processed  and  stored  in memory and constitute a measured absorption pattern. Once acquired for a frequency range,  this pattern is compared to the theoretical  transmission pattern of the  optical  filter.    Correspondences  are  made  to identify the transmission features against their known counterparts.   A relationship between the  frequency control  signal  and actual  frequency of  the  optical source is established.   The frequency calibration of the  optical  source  over  many  frequency  points  is therefore  achieved.    The  disclosed  arrangement  is especially  suited  to  the  frequency  calibration  of tunable  laser sources,  such as  semiconductor  lasers and   external   cavity   lasers.      Four   specific applications  of  this  absolute  optical   frequency calibrator  are  disclosed.    The  first  one  is  the discrete  ou  continuous  calibration  of  a  variable frequency optical source itself. The second one is the automatic  and  unambiguous  locking  of  the  optical frequency source relative to a selected transmission feature of the optical filter. The third application is the optical frequency measurement of a non-tunable optical  source  using  a beat  note  technique  with  a previously frequency-calibrated  variable  frequency optical   source.   The   fourth  application  is   the frequency  control  of  an  optical  source  using  the frequency measuring technique proposed in the  third application.

Granted: 2001-08-07
Abstract: In accordance with the present invention, a radio communications system is disclosed that can operate in one of several Modes which integrate in-building security, location determination, messaging, and data communicationscapabilities. The radio communication system includes at least one Interrogator for generating and transmitting a radio signal. One or more Tags of the system receive the radio signal. A Backscatter Modulator modulates the reflection of the radio signal using a subcarrier signal, thereby forming a reflected modulated signal. The Interrogator receives and demodulates the reflected modulated signal. The Interrogator can also transmit a first information signal to one or more tags, specifying which tags should respond using Backscatter Modulator means. In the Interrogation Mode, the Interrogator can determine the identity of the Tags in the reading field, and can exchange data with those Tags that have been identified. In the Location Mode, the radio communications system can instruct some or all Interrogators to determine the location of a Tag or Tags within the building, regardless of whether the Tag or Tags are in radio range of the Interrogation Mode. In the Messaging, or low speed data communications Mode, the radio . communications system can instruct some or all Interrogators to transmit a command addressed to a particular Tag or Tags, regardless of whether the Tag or Tags are in the reading field of the Interrogation Mode, requesting that Tag or Tags performsome action. Other embodiments of the Messaging Mode allow the Interrogator to transmit data in addition to a command to the Tag or Tags, and also for the Tag or Tags to transmit a signal back to the Interrogator. This radio communications system can be interconnected with other communications capabilities such as electronic mail, voice mail, location, inventory management, and other systems.
