Patent EP-0649578-A4 (EP)
Title: Digital filter having high accuracy and efficiency.
Inventor: MCGRATH DAVID STANLEY
IPC: H03H17/02
Filed: 1993-07-05
Abstract: Apparatus for and methods of operation of digital filters and certain other electronic digital signal processing devices are provided to improve the accuracy and efficiency of filtering. Particularly, the apparatus and method includes a digital filter with a long impulse response and lower latency, built by operating a numbr of small component filters (F1, F2, F3) in parallel and combining their outputs by addition, with each component filter operating with a different delay such that the net operation of the ensemble of said component filters is the same as a single filter with a longer impulse response, and the latency of the ensemble is equal to the shortest latency of the component filters. At least one group of the component filters is implemented using a Discrete Fourier Transform technique. A Fourier transform processor adapted to efficiently transform strings of real data is also described.

Title: Waterproof, gasketless enclosure.
Inventor: WYLER CRAIG S
IPC: H02G15/113
Filed: 1993-05-25
Abstract: A gasketless enclosure (10), for housing outdoor electrical equipment, includes a box (12) having a base (14) and upwardly extending sidewalls (16A-16D). The walls define an open top over which fits a cover (18). A closure mechanism (28) includes an upwardly projecting lip (30) formed at the top of the sidewalls and extending around the box, and a channel (32) formed in the abutting face (34) of the cover and sized to receive the lip. To help keep out moisture, gutters (42, 44) are formed in the abutting surfaces of the box and the cover. The gutter (44) is formed outwardly of the lip, and the gutter (42) is formed outwardly of the channel. The gutter (42) is above the gutter (44) when the cover is in place. The gutter formed along the top and sides of the box is open at the bottom of the enclosure to provide a drain (45) for directing moisture to the outside of the box.

Title: A self aligning method for forming a selective emitter and metallization in a solar cell
Inventor: WENHAM STUART ROSS
IPC: H01L31/0224
Filed: 1999-06-29
Abstract: A method of making contacts on solar cells is disclosed. The front surface (41) of a substrate (11) is coated with a dielectric or surface masking layer or layers (12) that contains dopants of the opposite polarity to those used in the surface of the substrate material (11). The dielectric layers or layers (12) not only acts as a diffusion source for forming the emitter for the underlying substrate (11) when heat treated, but also acts as a metallization mask during the subsequent electroless plating with solutions such as nickel and copper. The mask may be formed by laser scribing (14) which melts the layer or layers (12), thereby more heavily doping and exposing zones (15) where metallization is required.

Title: Strictly non-blocking optical switch core having optimized switching architecture based on reciprocity conditions
Inventor: LIN PHILIP J
IPC: H04Q11/00
Filed: 1999-09-07
Abstract: A switch core is set forth that comprises a plurality of duplex switches that are interconnected with an interconnection fabric to implement, for example, strictly non-blocking operation of the switch core for reciprocal traffic. In one embodiment, an N-way reciprocal switch is implemented. The N-way reciprocal switch comprises a plurality of duplex switches numbering N of at least a 1x(N-1) switch type (e.g., the duplex switches have at least N-1 ports available for connection to implement the interconnection fabric). The interconnection fabric interconnects the plurality of duplex switches so that each duplex switch is connected to every other duplex switch used in the interconnection fabric by a single connection. A similar architecture using switches numbering N of at least a 1xN switch type is also set forth. Still further, a plurality of duplex switches are used to implement an (n,m)-way switch that, in turn, can be used to construct a recursive LM-way switch core and/or recursively expand an existing Clos switch core.
