Title: Fluid pump dispenser having product retraction feature
Inventor: RIBERA TURRO VICTOR
IPC: F04B53/10
Filed: 2001-03-12
Abstract: A fluid pump dispenser of the loss motion piston type provides for maintaining the discharge open a slight interval at the commencement of each plunger upstroke while the pump chamber expands to retract product from the discharge passage into the chamber to thereby avoid the formation of product droplets at the exit end of the discharge. Such is effected in accordance with one embodiment by reducing the friction force acting between the piston and the pump cylinder relative to the friction force acting between the piston and the stem. In another embodiment an inlet valve assembly has a portion lying in the path of the piston which portion is connected by spring legs to a valve portion such that the restoring force of the spring legs shifts the piston together with the stem at the commencement of the plunger upstroke which maintains the discharge passage in open communication with the chamber.

Filed: 1999-10-19
Abstract: An instrument valve manifold (10, 210) interfaces between a flowline control manifold CM and one or more pressure transmitter units (T1, T2). The instrument valve manifold includes a monolithic body (32, 232) that defines a mating surface (34, 234) having a low pressure port (52, 252) and a high pressure port (54, 254), a low pressure plenum (58, 258) and a high pressure plenum (60, 260), and at least one equalizing valve pocket (96, 296) for receiving an equalizing valve (100, 300). Fluid passageways in the body (32, 232) extend from the low pressure input port to the low pressure plenum and from the high pressure input port to the high pressure plenum. The instrument valve manifold reduces the size and weight of components connected to the control manifold, reduces the moment arm of the combined weight of the instrument valve manifold and the transmitter on the control manifold, and distributes the weight substantially equally about the plane of symmetry (30) of the control manifold.

Patent CA-2350082-A1 (CA)
Title: Color enhancement method
Inventor: CHRISTOFF JORDAN C
IPC: H04N9/73
Filed: 1999-11-12
Abstract: A color enhancement method for use in a video camera imaging system (10, 30) in the context of non-uniform lighting includes an adaptive algorithm (100- 110) for developing a shutter speed control signal, analog gain control signal and color balance signals from pixel luminance over one filed of video. The control signals developed during one field are used to control the camera (12) during the next field. The speed control signal and analog signal are determined based on the luminance signal obtained in digital form from the video camera, and analyzed over at least one field of video. During one field, the speed control signal and the analog gain signal target dark areas of the image and during the next field they target the bright areas of the image so that, over two fields, every pixel is within a workable range of luminance in at least one of two alternate fields.      As the color balance settings for the fields are adjusted according to the exposure settings and the luminance level, consistent hue values are maintained between alternate fields. Additionally, a pixel color detection circuit (18, 28) examines each pixel from the video camera (12) to determine whether it is in a color region of interest. The pixel color detection circuit uses a color offset signal, calculated by a controller (16, 60) based on the luminance signal during the preceding filed. The color offset signal indicates how far from neutral, or white, in the chosen color space, is the chrominance data from the camera.      The video camera and pixel color detection circuit may be sued to identify weeds or plant material on the ground. A controller (74) is responsive to the pixel color detection circuit and activates one or more spray nozzles (68, 70) when a weed is detected.

Title: Gestion de files d'attente dans des reseaux a commutation de paquets
Inventor: ENGSTRAND ROLF GEORG
IPC: H04L47/30
Filed: 1999-11-17
Abstract: Dans une liaison multipoint à point, les paquets (T) sont transmis à un noeud central (10) via un support partagé en réponse à des permis (TP). Le noeud central (10) émet des permis pour un noeud multipoint (20) en fonction d'un enregistrement de longueur de file d'attente (11) tenu à jour au niveau du noeud central. L'enregistrement de longueur de file d'attente est mis à jour à la réception d'un compte rendu de longueur de file d'attente (demande de permis) (RP) provenant du noeud multipoint. En raison des retards de transmission par la liaison, une valeur de file d'attente erronée peut être enregistrée au niveau du noeud central lorsque des permis et une demande de permis sont envoyés sensiblement au même moment. Ce problème est résolu, et la capacité de transfert est améliorée lorsque le noeud central tient à jour un enregistrement des permis envoyés pendant le retard d'aller et retour précédent. Toute demande de permis entrante est alors corrigée du nombre de permis stockés avant qu'elle ne serve à la mise à jour de l'enregistrement de file d'attente.

Abstract: Methods are described for assessing an individual's risk for developing early-onset glaucoma, and for developing glaucoma with a high intraocular pressure at onset of disease, by assessing the ApoE alleles and/or the ApoE gene promoter alleles of the individual. In individuals carrying mutations in the TIGR gene, the presence of an ApoE4 allele is indicative of an increased risk of developing early-onset glaucoma. In individuals carrying mutations in the TIGR gene promoter, the presence of an ApoE4 allele is indicative of an decreased risk of developing glaucoma with a high intraocular pressure at onset of disease. The combination of an ApoE4 allele and a "T" allele of a ApoE gene promoter in an individual carrying a mutation in the TIGR gene is also indicative of an increased risk of developing early-onset glaucoma. The presence of a "T" allele of an ApoE gene promoter, regardless of whether a mutation in the TIGR gene is present or absent, is indicative of an increased risk of developing glaucoma with a high intraocular pressure at onset of disease.

IPC: A63B69/36
Filed: 2000-06-29
Abstract: The present invention involves a golf tee (22) coated with colored coatings (24) that when struck with a golf club (44) leave a marking that easily identifies where the ball (26) was struck on the club face and the path of the swing, but does not come off in normal handling. The tee leaves a multi-colored marking on the club face that is used to show the swing path of a golfer's swing and the point of impact of the tee on the face of the golf club. The tee has a center line or mark that represents the middle, which establishes the optimum hitting area. This line or mark is also an indicator for the golfer to line up in the direction they are trying to hit the ball. On either side of this colored line or mark is a different color that indicates the swing path when shown on the club face.
