Appl. No.:

12/753705

Inventors:

Abhimanyu Das - Los Angeles CA, US
Deyi Dong - Shanghai, CN
Eugene Lee - San Jose CA, US
Dongsheng Zhang - Fremont CA, US

Assignee:

CORTINA SYSTEMS, INC. - Sunnyvale CA

International Classification:

H04L 1/00

US Classification:

370230

Abstract:

A method of operation of a network transport system includes: determining a congestion mode based on a total bandwidth request meeting or exceeding a bandwidth threshold, where the congestion mode indicates a level of network traffic and the total bandwidth request is a sum of all bandwidth requests for accessing the network; calculating a fixed information rate schedule grant based on a fixed information rate list to create a bandwidth grant for a fixed information rate request; calculating a low latency schedule grant based on a low latency list to create the bandwidth grant for a low latency request; calculating a main schedule grant for allocating an available bandwidth based on the congestion mode, where the main schedule grant is calculated using a weighted maximum-minimum fairness method when the congestion mode indicates congestion; and generating a grant packet for defining a transmission schedule of a first network unit.

US Classification:

370235

Abstract:

There are disclosed systems and methods for detecting and controlling congestion in an Optical Line Terminal (OLT). The OLT has a plurality of ports. Each port of the plurality of ports communicates with at least one Optical Network Unit (ONU), and each port of the plurality of ports has a respective enforced maximum upstream bandwidth. For example, the maximum upstream bandwidth may be enforced by a Dynamic Bandwidth Allocation (DBA) algorithm. The OLT further includes an uplink port through which data received from each of the plurality of ports are transmitted. In one embodiment, if there is congestion of the data at the uplink port, then the enforced maximum upstream bandwidth for at least one port of the plurality of ports is modified.

Inventors:

Eugene O. Lee - Long Beach CA

International Classification:

F16K 144

US Classification:

251171

Abstract:

The invention is an improved valve mechanism for controlling the flow in conduit to be used in combination with an adjustable valve. The adjustable valve includes a T-shaped valve body having a first bore extending therethrough and a second bore adjacent to the first bore. The adjustable valve also includes a stem having an inner end and an axially outer end which extends through one of the ends of the first bore and a device for forming a seal between the first bore and the stem. The valve mechanism includes a cylindrically shaped sealing member having a bore axially aligned with the first bore of the valve body and being disposed within the first bore adjacent to the end thereof oppositely disposed from the stem. The sealing member has a cylindrical inner sidewall and a truncated-conical outer sidewall adjacent to its top portion and a cylindrical outer sidewall adjacent to its bottom portion. The valve mechanism also includes a cylindrically shaped valve member which is adapted to slideably engage around the outer cylindrical sidewall of the sealing member and which is mechanically coupled to the stem so that its inner sidewall may travel along and adjacent to the outer sidewall of the sealing member.

Abstract:

A system and method of controlling auxiliary vehicle functions via one or more touchpads on the vehicle steering wheel is disclosed. In response to receiving a user input at one of the touchpads, the vehicle performs a corresponding action depending on the region of the touchpad in which the input was received and the context in which the vehicle is currently operating. During operation, the vehicle displays, on a display screen of the vehicle (e.g., the HUD), a contextual control image indicating which actions will be performed in response to various inputs entered at one or more of the touch pads on the steering wheel. In this way, the steering wheel can accept an input for a variety of auxiliary functions.

Abstract:

A camera system for vehicles captures panoramic video, has a unique identifier, and has an image processor that compresses the video and detects events. It transmits compressed video with one or more of a timestamp, a unique identifier, a location, and event flags through a network (e.g., cellular) to a server. A GPS device (or the like) may be adapted to determine location. Particular embodiments process the video to detect events, and, upon detecting these events, transmit video at a high data rate while using a low data rate at other times.
