Title: Lensed cascaded optical filter
Inventor: KAWASAKI BRIAN S
IPC: G02B6/34
Filed: 1998-04-24
Abstract: A multi-pass optical filter using two identical filters provides narrower band filtering by double filtering an optical signal passing therethrough. Although passing a beam of light at an optical filter having a substantially thick optical thickness is known to have significant coupling losses due to angular misalignment of the output beam and the receiving optical fibre, it has been found that twice filtering in the conventional manner by serially coupling two same filters increases coupling losses. However, this invention provides a coupling arrangement wherein losses are significantly lessened by offsetting the axes of the lensed filters such that the beam exiting the first filter couples into the second filter as it would be reflected backward into the first filter.

Title: Automatic control of air delivery in forced air furnaces
Inventor: TONNER ROBERT B
IPC: F24H9/20
Filed: 1998-05-13
Abstract: A forced air furnace circulation fan controller adjusts the speed of the circulation fan according to the incidence of air delivery restrictions.   Upon detecting insufficient air delivery as a function of the temperature of the furnace heat exchanger, the control system increases the circulation fan speed to increase the air delivery within the heating system. The controller utilizes fuzzy logic techniques to determine a speed adjustment for the furnace fan motor, based on the value of the furnace heat exchanger temperature. The use of fuzzy logic control allows the circulation, fan controller to provide a highly adaptive response to changes in air delivery.   The resulting balanced air delivery provides for efficient furnace operation and superior occupant comfort.

Abstract: The present invention relates to a method for suspending the rails, tracks, or the like of a lifting apparatus on a beam, with at least one cable that connects the beam and the tracks, the ends of the cable being connected to each other by a connector, so as to be releasable. In order to prevent the redundancy suspension system parting and falling, or the cable being damaged by the cable clamps, in the event of a sudden load, for example if the rail attachments break, it is proposed that the connector (10) consist of two wedge locks (12, 13) that can be joined to each other to form one structural element, these wedge locks being arranged in such a manner that the one wedge lock (12) be rotated through 180° relative to the other wedge lock (13). Thus, the effective directions of the wedges (18 close, 19) that clamp the cable ends (9a, 9b) are opposed to each other. The cable ends (9a, 9b) that enter from opposite directions can be returned in the direction opposite to their direction of entry after passing around the wedges (18, 19) of the wedge locks (12, 13), and they can be clamped by the wedges (18, 19), at least when under load.

Title: Digital video security system
Inventor: BAKSHI RAJEEV K
IPC: G08B13/196
Filed: 1998-07-06
Abstract: An embedded system for video monitoring and security is disclosed. The embedded system includes a video camera, a user programmable motion detection sub-system which activates the camera and a solid state storage mechanism for collecting the digital video images. All three of the functional units as well as additional hardware and software required for image analysis, compression, storage, playback, and a user interface are all contained within the same vandal resistant enclosure, which is relatively small and easily mountable to almost any surface. Digital video images captured by the camera are processed and continually monitored for unexpected motion. The required memory capacity is reduced by storing the video images in a "time lapse" fashion and storing only when the storage subsystem is triggered by the motion detection subsystem. The solid state storage media provides for increased reliability over older mechanical forms of memory. The user interface takes the form of an on-screen display, where the user can program many system features including: aspects of the motion detection and storage subsystems.

IPC: A01H1/04
Filed: 1998-05-14
Abstract: The present invention provides a method for the production of hybrid wheat based on the ability to stably maintaining a genic male-sterile female parental line of common and durum wheat. It also provides a male-sterile female line homozygous for a recessive male-sterility allele and for a dominant pollen-killing allele, and a maintainer line which is readily and stably propagated. The maintainer line is isogenic to the female line but has an alien engineered chromosome carrying a dominant male-fertility allele that restores fertility to the maintainer line, a recessive pollen-killing allele that is susceptible to the killing effect of the native pollen killer thus preventing the transmission of this chromosome to the female line, and one or more selectable markers that facilitate the maintenance of the maintainer itself. The invention also provides procedures for converting any desired cultivar into male-sterile female line and into a maintainer line.

Abstract: A device for optically examining and/or treating a patient's eye has a lighting and/or observation optical unit (3) that can be freely moved and oriented in the direction of all co-ordinates in space above the left or right eye (29) and has a flat area that can be set on the surface of the eye. The optical unit is preferably retained in the adjusted position relative to the eye so as to maintain itself in a fixed position in relation to the patient's head and to move together with the head, when the patient can move his head. The treating doctor thus does not need to carry out manual positioning and/or securing operations while diagnosing and/or treating the patient. On the contrary of known optical treatment devices, unwanted degrees of freedom of motion are excluded by the disclosed device, and the risk of injuries is considerably reduced. In particular, laser beams can be more safely used for treating the eye.

Abstract: An optical adapter [100] includes a pair of cylindrical ferrules [121, 122], each containing an optical fiber disposed along its central axis [101-101].  The ferrules are aligned with their central axes being collinear. Moreover, the ferrules are captured within a plastic housing that comprises a plug member [110] and a jack member [140]. These members interlock with each other to form an adapter that can be used, for example, for attenuating an optical signal or for interconnecting two ferrules having different diameters. Preferably, the ferrules are identical to each other. Each ferrule includes an optical fiber that is disposed in a bore, which extends along the central axis of the female between its opposite ends, and each ferrule has an end face [126] that is angled at about 82 degrees with respect to the central axis. In one embodiment, the angled end faces of the ferrules are in direct contact with each other and attenuation is determined by the optical path length between the centers of the angled end faces, which is a function of the axial rotation of the ferrules with respect to each other. In another embodiment, the angled end faces of the ferrules are in contact with opposite sides of a spacer [170] so that attenuation is a function of the spacer's thickness and the axial rotation of the ferrules with respect to each other. Such a design enables precision optical attenuators to be fabricated. Wavelength division multiplexing systems are improved by the use of such precision optical attenuators at the inputs of the multiplexer [200] and/or the outputs of the demultiplexer [500].
