Jul 21, 2006

Appl. No.:

11/309288

Inventors:

Min Sig Kim - Rowland Heights CA, US

International Classification:

E04C 2/38
E06B 3/72

US Classification:

5280014, 5220465, 52204597

Abstract:

A door frame system includes a frame, a fixed bench, a pressure bench and a compression rail combined to the frame. The pressure bench moves horizontally by a tightening bolt so as to compress and fasten a glass pane, and a brush assembly is combined to a lower space portion of the frame. With the tightening bolt in a locking position, the compression rail is lifted up along an inclined guide surface and horizontally moves the closely contacting pressure bench. The frame and the glass pane can be firmly combined without being pushed out from each other and a door of a precise standard can be provided.

Abstract:

A method for encoding a bitstream is described. The method includes receiving, by an error correction unit, the bitstream; performing, by the error correction unit, encoding on the bitstream to generate an encoded bit stream that includes the bitstream and parity bits; processing, by a constellation unit, the encoded bitstream to generate constellation points in one or more encoded streams; determining, by a low-density parity-check (LDPC) tone mapper, a distance between subcarriers in an Orthogonal Frequency Division Multiplexing (OFDM) symbol of the frame; and performing, by the LDPC tone mapper, LDPC tone mapping based on the one or more encoded streams and on the determined distance to generate a permuted stream of complex numbers, wherein the distance between subcarriers is determined to be either (1) 18 for a first resource unit size used in the frame and (2) 20 for a second resource unit size used in the frame.

H04W 72/04

Abstract:

A method includes determining, by a Media Access Control (MAC) layer of a first wireless station, a total length of user data in a first Physical Layer (PHY) Protocol Data Unit (PPDU); determining, by the MAC layer, a Hybrid Automatic Repeat Request (HARQ) block size; adding a first indication to a transmission vector, wherein the first indication indicates the total length of user data in the first PPDU; adding a second indication to the transmission vector, wherein the second indication indicates the HARQ block size; passing the transmission vector to a PHY layer of the first wireless station; generating, by the PHY layer, the first PPDU based on the first indication and the second indication, wherein the first PPDU includes a first set of HARQ blocks that each have a size equal to the HARQ block size; and transmitting the first PPDU to a second wireless station.

Abstract:

Event processing is a vital aspect of modern information systems, but is poorly supported and homogenous in nature. The present disclosure recognizes that any detector speaks a language of events. This language of events can be translated into a “Universal Language” such that events from multiple arbitrary detectors may be compared together. The present disclosure uses regular expressions to explore possible relations and patterns across events and across time. The present disclosure further describes a hierarchical architecture such that the events from peer detectors are aggregated and collated and only conglomerate events, those events matching inter- or intra-detector behaviors, are propagated upstream in the hierarchy. Ultimately, this architecture offers a means to merge the event data from an arbitrary number of heterogeneous detectors into a meaningful stream of events that reflect wider breadth of knowledge, improved scalability, and provide a wider context for expression of patterns through the use of regular expressions.
