Patent number: 6616018Abstract: Fluid dispensing apparatus (10) for selectively dispensing desired quantities of a fluid under pressure. The apparatus includes a base plate (14) having a dispensing passage (16) extending about a first axis (18); a valve arrangement (20) associated with the dispensing passage (16), and a piezoelectric transducer (22) acting on the valve arrangement (20) to effect displacement of the valve arrangement between a first position in which the dispensing passage (16) is closed and a second position in which the dispensing passage is connected to a source of the fluid under pressure. The valve arrangement (20) includes a slide valve (24), with the slide valve and the piezoelectric transducer (22) being arranged such that during at least initial displacement of the valve arrangement from the second position towards the first position, the slide valve (24) is displaced in a direction transverse to the first axis (18).Type: GrantFiled: June 18, 2001Date of Patent: September 9, 2003Assignee: Markpoint ABInventors: Patrik Jonasson, Lennart Sjöstedt, Lennart Sven Thålin, Mats Pegelow, Göran Nybom, Ove Andersson

Patent number: 6361148Abstract: A direct electrostatic printing device and method print an image to an information carrier with improved alignment between printed part images from two or more print stations. The improved alignment is based on a basic mechanical alignment with a basic accuracy between the print stations which is improved by an electronic alignment of the corresponding bitmaps. The electronic alignment is made possible by the capability of at least one print station to print at least one additional dot in relation to the corresponding bitmap. The minimum number of additional dots being dependent on the attained basic accuracy of the basic mechanical alignment.Type: GrantFiled: June 15, 1999Date of Patent: March 26, 2002Assignee: Array Printers ABInventors: Tomas Jonsson, Anders Ingelhag, Göran Nybom, Henrik Gustavsson, Krister Uvnäs, Lennart Sjöstedt, Lennart Thålin

Patent number: 6014210Abstract: A device for optical analysis of a specimen, especially a blood sample, is in the form of a dish, a translucent plate-shaped portion, which has a specimen-receiving surface, essentially constituting the bottom of the dish, and a frame, which engages the plate-shaped portion, forming its wall. To catch surplus liquid from the specimen-receiving surface, especially when receiving, smearing, spinning or coloring the specimen, an absorbing material is arranged in a loop along the circumference of the plate-shaped portion. The design of the device permits safe and easy handling of specimens that are injurious to health.Type: GrantFiled: April 14, 1997Date of Patent: January 11, 2000Assignee: CellaVision ABInventors: Christer F.ang.hraeus, Patrik Soderlund, Lennart Sjostedt, Ragnar Segersten

Patent number: 5956413Abstract: In automatic evaluation of cereal kernels or like granular products handled in bulk, the kernels are conveyed on a vibrating conveyor belt (15). Owing to the vibrations, the kernels are spread and settled in grooves (14) in the belt so as to be oriented in essentially the same direction. A video camera (40) produces digital images of all the kernels on the belt. The kernels are identified in the images, and for each kernel input signals are produced and then sent to a neural network based on picture element values for the picture elements representing each kernel. A neural network then determines which of a plurality of predetermined classes that each kernel belongs.Type: GrantFiled: December 23, 1997Date of Patent: September 21, 1999Assignee: Agrovision ABInventors: Rickard Oste, Peter Egelberg, Carsten Peterson, Patrik Soderlund, Lennart Sjostedt

Patent number: 5426989Abstract: For carrying out a method to displace an object from a resting position to to a working position or vice verse, a device (1) is arranged comprising a screw (3) with two threads (7, 9) with different pitches and a body (2, 4) with internal threads matching the threads of screw (3). The body is shaped in two parts (2) and (4), which are arranged to be able to be displaced relative to one another in the axial direction of the screw (3), whereby a changing from one thread to another thread can be done by changing the distance between said parts (2, 4) of the body. The screw (3) is arranged to a first object and the body (2, 4) to a second object.Type: GrantFiled: June 3, 1993Date of Patent: June 27, 1995Inventors: Jack Uhlmann, Patrik Soderlund, Lennart Sjostedt, Pierre Stahl
