Title: Apparatus for operating bin lid from below
Inventor: POLLOCK EUGENE B
IPC: E05F11/04
Filed: 1992-11-12
Abstract: An apparatus for opening and closing a top bin lid (24) from below such that, when in the fully opened position, the lid (24) will not extend above the plane of the opening. The apparatus utilizes an elongated lever arm (32) pivotally mounted on the pivot axis (28) of the bin lid (24). A flexible linkage, such as a chain (34) extends from below, over the lever arm (32) which holds the lid (24) in the closed position until the chain is pulled from below. After the latch (30) is released, further drawing of the chain will pivot the lid and arm about their common pivot axis (28) until the arm (32) is obstructed from further movement by the bin (10). Continued pulling of the chain will draw he lid toward the lever arm against spring pressure until the lid (24) has been pivoted approximately 180° from its closed position.  Controlled re-lease of the chain will cause the spring pressure to move the lid over the vertical plane of the pivot axis and thereafter the force of the spring and gravity will return the lid and latch back to the closed position. The lever arm includes a lid engage-ment tab which returns the lever arm to its upwardly extending position when the lid closes.

Patent CA-2140681-A1 (CA)
Inventor: CHEVRETTE PAUL C
IPC: H04N5/45
Filed: 1995-01-20
Abstract: An imaging system wherein two field-of-views (FOVs) images of a scene are obtained and displayed as a single image so that both FOVs can be viewed simultaneously by an observer.          This imagining system is particularly directed to infrared (IR) imaging of a scene which is useful for search-and-rescue (SAR) operations.  One IR image sensor provides a low resolution, high sensitivity, wide field-of-view (WFOV) image of the scene which is displayed as a large, low resolution, WFOV image on a display apparatus.  A second IR sensor provides a high resolution narrow field-of-view (NFOV) image of a selected portion of the scene wherein the second sensor's NFOV optics can be directed to any particular area within the WFOV.  That smaller NFOV image is also displayed, by the display apparatus, within the WFOV displayed image and it is displayed at the same area in the WFOV image as that actually covered by the NFOV, the NFOV image displacing the WFOV image of that area with the two images being fused together into a single image by the display apparatus.          This is rather similar in operation to an observer's eye which has a high resolution central NFOV vision and a very large FOV peripheral vision that has low resolution but a high sensitivity to detection of any anomaly.  By using an eye movement tracking system to aim the NFOV image detector and the position that the NFOV image is displayed, an observer's central vision can always be directed to the high resolution NFOV image with that observer's peripheral vision simultaneously viewing the WFOV low resolution image.

Abstract: By providing a digital video memory arrangement with first and second address generating means, digital video signals can be written at a first location of a non-mechanical memory and (almost) immediately read out from a second location of the non-mechanical memory, with the reading out both being capable of featuring backward and forward jumps. As a consequence of a coupling between the first and the second address generating means it becomes impossible to, on the one hand, unjustly pass with jumping in the read signal the running or stopped write signal and, on the other hand, unjustly pass with the running read signal the stopped write signal. To this end the second address generating means dispose over determining means for determining, in response to at least the write signal and the read signal, a permitted address jump. <MATH>

Abstract: In a method of manufacturing a semiconductor device comprising a semiconductor chip and a carrier film which includes an insulating film and wiring patterns formed on one of main surfaces of the insulating film, an adhesive layer is formed on a surface of a semiconductor wafer having a number of integrated circuits. Each of the integrated circuits has electrode pads for external connection on the foregoing surface of the semiconductor wafer. Subsequently, openings are formed at regions of the adhesive layer corresponding to the electrode pads, and then, the integrated circuit is cut from the semiconductor wafer so as to obtain the semiconductor chips.      Thereafter, the electrode pads of the semiconductor chip and the wiring patterns of the carrier film are connected to each other through the corresponding openings of the adhesive layer, respectively. Then, the semiconductor chip and the carrier film are bonded together via the adhesive layer interposed therebetween. It may be arranged that the adhesive layer is formed on the carrier film rather than on the semiconductor chip.
