摘要:
The present application describes a method for transmitting data through a MIMO-OFDM system which requires the computation of a function f(H(sk)), where H is the channel matrix and sk=exp(j*2*pi*k/N). The method splits function f into a first, nonpolynomial part, which is in turn a function of one or more polynomial functions in sk.

摘要:
A guiding device for a rotatable, circular saw blade of a house-building saw. Such a saw comprises a bench-shaped stand (2) with a frame (98) which is movable therein and on which the saw blade (12) is rotatably mounted, and an operating mechanism (26) for raising and lowering the frame (98) in the stand (2). According to the invention the guiding device comprises guide elements (90, 92) whereby the frame (98) can also be moved along the bench surface (4) after the frame (98) has been moved to near an upper position.

A bowling lane having a substantially flat top surface including a foul line end and a pin deck end, the improvement comprising a method and assembly of a polymer sheet of polycarbonate having a thickness between about 0.63 and 2.50 mm, overlaid onto the top surface between the foul line end and pin deck rear end and having a leading edge portion and a trailing edge portion, a strip of double-sided adhesive tape beneath the leading edge portion for securing to the foul line end, and double-sided tape beneath the trailing edge portion for securing it at the pin deck end. Any other mechanical fastening system may also be used to adhere the sheet to the lane. The polymer sheet may be 100% polycarbonate, but may also include a first layer that optionally comprises a lubricious polymeric material such as Teflon® in combination with polycarbonate. The polymer sheet undersurface is free of adhesive. A similar sheet, preferably of slightly greater thickness, is preferably applied to the approach and adhered at the front and rear edge portions by strips of double-sided tape across the width of the approach. A similar sheet may also be applied to the pin deck area.

Power is supplied to telecom equipment in DSLAM outdoor/remote cabinets with relatively short distances between the subscriber and the cabinet. All of the subscriber Customer Premises Equipment connected to the DSLAM each provide a portion of the required power to the remote cabinet via the telephone line connecting the DSLAM and the subscriber CPE. The CPE at the subscriber premises is already connected to power mains in the subscriber premises so, providing power, via the telephone line to the outdoor cabinet is relatively simple. The remote cabinet includes a circuit for receiving the power input from each subscriber and then distributing the power, required by the DSLAM load, equally among the subscribers.
摘要:
A production light comprising a housing (1) with a synchronous driving mechanism with at least two rollers (2,4) where a film/band (6) of gels (8) is wound and taut between the rollers (2,4) so the aperture (10) of the production light is covered by the film/band (6), characterized in that the film/band (6) comprises of a plurality of separate sections of gels (8) where the gels (8) are attached to the film/band (6) by fastening means in such a way that each section of gel (8) is easily mounted or remounted onto the film/band (6).

A display and method for bowling centers and the like includes at least one bowling lane having a base member with an approach area, pin deck area and lane area extending therebetween. A generally transparent synthetic sheet member is positioned over at least a portion the base member, and has a leading edge attached to the base member to retain the sheet member in an overlying relationship with the base member, leaving at least a portion of the sheet member unattached to define an insert area. At least one display card with in a generally thin profile is inserted between the sheet member and the base member at the insert area, such that the indicia are visible through and protected by the sheet, with the weight of the sheet member retaining the display card in place to facilitate easy insertion and removal of the display card to provide varied displays.
