A self supporting roof structure comprises a plurality of vertically adjacent circular upwardly inwardly inclining at least partial rings stacked one on another. Each ring comprises a plurality of like horizontally adjacent panels each of which is an aliquot of the ring. Each panel comprises an outer surface which is convex from side to side, upwardly converging rectilinear sides, a concave top plate member, and a convex bottom plate member. The top and bottom plate members in each ring conform to respective upper and lower inwardly downwardly sloping conical surfaces of which the apex coincides with the axis of the roof structure. Preferably, at least one ring has a number of panels which is an integral number greater than one times the number of panels of the ring above. The roof has each panel disposed with its sides laterally staggered with respect to the sides of the panels in the rings above and below, thus avoiding lines of vertical weakness, and may be formed from panels which fall within a narrow range of sizes.

An interlocking mechanism for interlocking a first and a second low voltage switching devices, wherein each of the switching devices includes a movable contact part, a stationary contact part and, an actuating unit for operating the movable contact part in a direction and making connection or disconnection with the stationary contact part. The interlocking mechanism includes a first and a second housing connected to each other, a first and a second sliding bar. The first sliding bar is arranged on the first housing and connects to the actuating unit of the first switching device. The second sliding bar is arranged on the second housing and connects to the actuating unit of the second switching device. A sliding plane is defined and has a X- and Y-axis, the Y-axis being defined in the direction of motion of the actuating unit of the switching devices.

A detector arrangement, which comprises a rotatable microfluidic disc and a spectrophotometric detector unit. The arrangement is characterized in that the detector unit is based on surface plasmon resonance (SPR) and is capable of measuring an analyte within the detection microcavities, each of which is part of a microchannel structure.A microfluidic disc having an axis of symmetry and comprising microchannel structures, each of which has an upstream functional part that is at a shorter radial position than a downstream functional part. The disc is characterized in that there are detection microcavities (DMCs) in at least a part of said microchannel structures, and that each of said DMCs has an SPR surface on an inner wall and a detection detection window extending from the SPR surface to the surface of the disc.The use of the detector arrangement and microfluidic disc described above for determining: a) if the content in one or more of the DMCs is a liquid or a solid state or a gas, and/or b) a feature of an analyte that may be present in a liquid which is present in one or more of the DMCs.
摘要:
A detector for use in imaging applications includes at least one detector array, an array of photodetectors, and a continuous light guide disposed between the detectors and the photodetectors. The light guide is continuous over the entire area of the photodetectors and detectors. The thickness of the light guide is optimized based on the shape of the photodetector array. Each detector array includes a plurality of scintillator elements disposed in an M×N array, where “M” and “N” are independently selectable and are each at least one. A mechanism for maintaining the relative positions of the individual scintillator elements with respect to each other is provided. The retainer is further provided to enhance the separation between the individual detector arrays to define distinct boundaries between the position profiles of the scintillator arrays.

The present invention concerns a reinforced conductive layer (7). The layer is applied at a part (3a,b) of an electrical unit, e.g. a mobile telephone, which is to come into contact with another part (3a,b). The layer (7) will protect the covered material against corrosion due to formation of a galvanic element. In a preferred embodiment of the invention the layer (7) is made of the made material as the part (3a,b) which it will come into contact with. Furthermore, spaces (16) may be formed in assembly of a mobile telephone, which spaces (16) are surrounded by conductive material. (FIG. 1)
摘要:
A method for determining the course of another vehicle in relation to one's own vehicle by measuring the position of the other vehicle in relation to one's own vehicle with a transmitter/receiver system, such as a radar system permits course determination both on straight and on bend segments. According to the method, the side location of the other vehicle and one's own vehicle is determined at a position where the other vehicle is level with one's own vehicle, by moving the front vehicle backwards in time and/or moving the rear vehicle forwards in time, on the basis of position measurements of the position of the other vehicle. The side location of the other vehicle is compared with the side location of one's own vehicle, by which a measure of the discrepancy between the course of the other vehicle and the course of one's own vehicle is obtained. According to the invention, the position where the other vehicle is level with one's own vehicle may be determined on the basis of the inertial speed vector of the other vehicle at one or more points in time.

An auxiliary contact block for a low voltage contactor, wherein the contactor has a side wall including first and second recesses. The auxiliary contact block includes a first and a second housing, connected in parallel to each other, an actuation nipple extending out from the second housing, and a connecting mechanism for connecting the auxiliary contact block to the contactor. The connecting mechanism includes a snap-fit element for locking the auxiliary contact block to the contactor when it is at a latched position and being adapted to engage in the second recess provided on the side wall of the contactor, and a releasing member for unlocking the snap-fit element to an unlatched position and including a releasing bar arranged for receiving a pressing force. The releasing member is arranged on the second housing and further includes a wedge element connected to the pressing element.
