Abstract: A method and system for distributed spatial mode processing is disclosed a number of optical signals are received over an optical link. Each optical signal is received via a respective one of a number of spatial modes of the optical link. The optical link includes a particular spatial mode not used for the receiving. A first one of the number of optical signals received from a first one of the number of spatial modes is transferred to a second one of the number of spatial modes via the particular spatial mode, wherein the first one of the number of optical signals is transmitted via the second one of the number of spatial modes.

Abstract: A bladeless fan assembly for creating an air current includes a nozzle mounted on a base housing a device for creating an air flow. The nozzle includes an interior passage for receiving the air flow and a mouth for emitting the air flow. The nozzle defines, and extends about, an opening through which air from outside the fan assembly is drawn by the air flow emitted from the mouth. The nozzle also includes a heater for heating the air flow upstream of the mouth.

Abstract: Disclosed is a hair care appliance comprising a body, a fluid flow path extending through the body from an inlet through which a fluid flow enters the appliance to an outlet for emitting the fluid flow from a front end of the body, and an attachment for adjusting at least one parameter of fluid emitted from the appliance, the attachment comprising an upstream end for attaching to the appliance, wherein one or both of the front end of the body and the upstream end of the attachment comprises at least one magnet. The front end may comprise an end wall extending radially inwards of the body and comprising the at least one magnet or a plurality of magnets radially spaced about the end wall or a ring of magnetic material extending around the end wall. The upstream end may comprise a plurality of magnets radially spaced about an end face.

Abstract: The present invention relates to methods of synthesizing long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, in recombinant cells such as yeast or plant cells. Also provided are recombinant cells or plants which produce long-chain polyunsaturated fatty acids. Furthermore, the present invention relates to a group of new enzymes which possess desatorase or elongase activity that can be used in methods of synthesizing long-chain polyunsaturated fatty acids.

Abstract: To control privileges and access to resources on a per-process basis, an administrator creates a rule that may be applied to modify a token of a process. The rule may include an application-criterion set and changes to be made to the groups and/or privileges of the token. The rule may be set as a policy within a group policy object (GPO), where a GPO is associated with one or more groups of computers or users. When a GPO containing a rule is applied to a computer, a driver installed on the computer may access the rule(s) anytime a logged-on user executes a process. If the executed process satisfies the criterion set of a rule, the changes contained within the rule are made to the process token, and the user has expanded and/or contracted access and/or privileges for only that process.

Abstract: An autonomous vacuum cleaner comprising a main body comprising a dirty air inlet, a clean air outlet, an airflow path extending between the dirty air inlet and the clean air outlet, a separating apparatus arranged in the airflow path between the dirty air inlet and the clean air outlet, and an airflow generator for generating an airflow along the airflow path from the dirty air inlet to the clean air outlet. The airflow generator has a discharge portion which discharges airflow into a chamber formed in the main body, the chamber including an opening that is closable by a removable panel, wherein a power source is receivable within the chamber formed in the main body and is removable from the chamber through the opening.

Abstract: Blood separation systems and methods are provided for controlling the interface between separated blood components. The system includes a centrifuge assembly having a light-transmissive portion, a light reflector, and a fluid processing region therebetween. An optical sensor system emits a scanning light beam along a path toward the light-transmissive portion, which transmits at least a portion of the scanning light beam to the fluid processing region and the light reflector. The light reflector reflects at least a portion of the scanning light beam toward the optical sensor system along a path substantially coaxial to the path of the scanning light beam from the optical sensor system toward the light-transmissive portion of the centrifuge assembly. The scanning light beam may be a white light beam or narrow spectrum beam. The reflected beam may be directed through the optical sensor system via optical fibers.

Abstract: An upright vacuum cleaner comprising a vac-motor for drawing dirty air in through a floor-engaging cleaner head on the vacuum cleaner, a separating apparatus for separating dirt from the dirty air, an elongate air duct for carrying air to or from the separating apparatus, and a suction wand which is stored on the vacuum cleaner and which can be connected to the separating apparatus via a hose as required to clean above the floor. The external surface of the air duct defines an elongate recess for receiving the stored suction wand such that the air duct partly surrounds the stored wand. This provides a compact configuration.

Abstract: The present invention relates to methods of synthesizing long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, in recombinant cells such as yeast or plant cells. Also provided are recombinant cells or plants which produce long-chain polyunsaturated fatty acids. Furthermore, the present invention relates to a group of new enzymes which possess desaturase or elongase activity that can be used in methods of synthesizing long-chain polyunsaturated fatty acids.

Abstract: Provided are imaging agents comprising a compound of Formula I, or a pharmaceutically acceptable salt thereof, and methods of their use.

Abstract: An autonomous vacuum cleaner comprising a main body having a dirty air inlet, a clean air outlet, an airflow path between the dirty air inlet and the clean air outlet and a primary separating apparatus arranged in the air flow path between the dirty air inlet and the clean air outlet. The primary separating apparatus comprises at least one cyclone, and the main body further includes a secondary separating apparatus in the airflow path downstream of the primary separating apparatus. The secondary separating apparatus comprises a container for holding dirt and debris which has an air inlet and a filter element, wherein the container is arranged in the air flow such that air flows into the container through the air inlet and out of the container through the filter element. The secondary separating apparatus is removable.
