Title: Key unlocking and retaining method and apparatus
Inventor: HENNESSY THOMAS F
IPC: E05B11/06
Filed: 1991-05-23
Granted: 1997-04-29
Abstract: A cylinder lock system employing a key having a projection extending from each opposing parallel edge of the key blade, the projections respectively operating an auxiliary pin tumbler stack and cooperating with a groove in the lock shell to retain the key in the lock after plug rotation from the key insertion position.  The key retaining projection also cooperates with the driver pin of the auxiliary pin tumbler stack to prevent key trapping, i.e., the presence and size of the retaining projections keeps the auxiliary driver pin from engaging the keyway. The cooperation between the key retaining projection and the auxiliary driver pin is permitted by providing the lock with two shear lines, located on different diameters, which are simultaneously operable by a single key.

Title: Equalizer for radio receive signal
Inventor: UEDA TAKASHI
IPC: H04L25/03
Filed: 1991-07-05
Granted: 1995-02-14
Abstract: In  a  transversal  type  equalizer having a  series connected delay elements, multipliers coupled with each output of  each delay element and an adder for adding outputs  of  said  multipliers  to  provide  an  equalized output signal for equalizing time division radio receive signal for every burst in mobile communication, a receive memory  (11)  for  storing receive signal,  a transversal type  equalization  process  circuit  (77a)  coupled  with output of said memory (11), and an output memory (100) for  storing  equalized output  signal  are  provided.  In training tap coefficients of a transversal filter, a tap or a delay element is precluded when an absolute value of a tap coefficient is less than a predetermined value, so that calculation amount for updating tap coefficients is decreased and tracking characteristics are improved;  a multiplier  (15)  is inserted between an output of said receive memory  (11)  and an input of said equalization process circuit (77a) so that a signal which is subject to  equalization  is  phase-shifted  beforehand  so  that frequency  offset  between  transmit  frequency  in  a transmitter  and  local  frequency  in  a  receiver  is compensated. The phase adjustment by said multiplier (15) depends upon  residual  phase  error at output of  said equalization  process  circuit (77a);  an  output  memory (100) is used as a training signal to initialize the tap coefficients of said equalization process circuit (77a) during a burst when equalized output signal has error larger than a predetermined value.

Patent CA-2055714-C (CA)
Title: Scene recognition system and method employing low and high level feature processing
Inventor: ALVES JAMES F
IPC: G06V10/426
Filed: 1991-11-15
Granted: 1997-01-07
Abstract: Image data is processed by a low level feature detection processor that extractslow level features from an image. This is accomplished by converting a matrix of im-age data into a matrix of orthogonalicons that symbolically represent the image scene using a predetermined set of attributes. The orthogonal icons serve as the basis of pro-cessing by means of a high level graph matching processor which employs symbolicscene segmentation, description, and recognition processing that is performed subse-quent to the low level feature detection. This processing generates attribute graphs rep-resentative of target objects present in the image scene. High level graph matching compares predetermined attributed reference graphs to the sensed graphs to produce a best common subgraph between the two based on the degree of similarity between the two graphs. The high level graph matching generates a recognition decision based on the value of the degree of similarity and a predetermined threshold. The output of the high level graph matching provides data from which a target aimpoint is determined, and this aimpoint is coupled as an input to a missile guidance system that tracks identi-fied targets.

Title: Method and apparatus for dispensing high viscosity fluid materials
Inventor: PORTER GEORGE O
IPC: B05C5/02
Filed: 1992-03-27
Granted: 2004-04-13
Abstract: A method and apparatus for dispensing a solution of highly viscous polymeric material and gas includes a dispenser connected to a pressure regulator which is adapted to connect to a source of a pressurized polymer/gas solution. Minimal pressure drop due to line losses occurs in the course of transmitting the solution from the pressure regulator into the dispenser because of their close proximity, and the solution is maintained under controlled pressure throughout passage to the discharge outlet of a nozzle carried by the dispenser so that the gas is maintained in solution in the polymeric material until it is discharged from the nozzle to atmosphere. The flow rate of solution through the dispenser is variable by operation of adjustable valve structure associated with the dispenser and/or by operation of the pressure regulator.

Title: User-interactive reduction of scene balance failures
Inventor: SCALISE ANTHONY
IPC: H04N1/46
Filed: 1991-09-13
Granted: 1997-12-16
Abstract: A photofinishing image processing operator detects failures in the performance of a scene balance mechanism on a digitized image and enables a photofinisher to interactively correct for such failures before the failed image has been processed and an unacceptable output image printed. Whenever a failed image is identified, one or more reasonably low resolution version of the image as processed by the scene balance mechanism are displayed to the photofinishing operator, together with a request for image adjustment information that is used to modify or correct the color balance of the image. In response to this user input information, the image processor adjusts color balance parameters of the scene balance mechanism, so that the digitized image processed by the modified scene balance mechanism will yield a print of acceptable color balance quality. This interaction of the photofinishing operator with the image processing system may be accomplished by way of several modes, including displaying differently processed versions of the image, or a single version of the image processed by the scene balance mechanism, together with a question regarding the type of image.  The failure detection mechanism preferably employs a non-linear discriminator, such as a neural network.

Granted: 1997-11-25
Abstract: The  isotopic  composition  of  a  multiatomic isotope-bearing species such as CO2  in an analyte is measured by maintaining the analyte in a condition such that isotope-bearing species are present in an excited state and directing light at wavelengths corresponding to transition energies of isotope-bearing species with different isotopes.  The interaction between the analyte and light at the different wavelengths is monitored, as by monitoring the optogalvanic  effect caused  by  the light of the different wavelengths.   The light may be supplied  by  a  laser  including  the  isotope-bearing species.   A stable isotope such as 13C or 18O can be used as a tracer in a chemical or biological test and detected using the composition-determining method.
