Filed:

Dec 13, 1999

Appl. No.:

09/459577

Inventors:

Kensuke Hazama - Yorba Linda CA
Dmitry Leshchiner - Irvine CA
Edward Schwalb - Irvine CA
Vincent Nguyen - Santa Ana CA

Assignee:

Amada Company, Limited - Kanagawa-Ken

International Classification:

G06T 1700

US Classification:

345420

Abstract:

A method, a system, and a computer program for graphically editing a computer generated sheet metal part model initially display the sheet metal part model on a computer display screen. The method, system, and computer program then select an entity of the sheet metal part model to edit, and select an editing operation to be performed on the selected entity. The method, system, and computer program also include performing the selected editing operation on the selected entity, and modifying the sheet metal part model in accordance with the performed editing operation. Finally, the method, system, and computer program display the modified sheet metal part model on the computer display screen so that a user views modifications of the sheet metal part model in real time.

International Classification:

H04B007/00

US Classification:

455522, 455427, 455 121

Abstract:

A power gating module () for a downlink beam frame signal () includes a power amplifier () for amplifying for transmission frame signals that include at least a first header signal (), a first payload signal (), a second header signal (), and a second payload signal (). The power gating module () further includes a power gating circuit () coupled to the power amplifier (). The power gating circuit () includes a power gate input () and is responsive to a power gating signal to remove power from at least one of the first header signal () and first payload signal () in combination, and the second header signal () and second payload signal () in combination before amplification by the power amplifier ().

H04Q007/00

US Classification:

37039531, 3703102, 370329

Abstract:

A downlink frame processing system () includes a packet switch () routing self addressed uplink data () from an input port to an output port, a memory () coupled to the output port, and a downlink scheduler () coupled to the memory (). The memory () includes storage for at least two downlink beam hop locations (). The downlink scheduler () processes from one of a plurality of segments at least one scheduling entry () that includes, for example, a header field () defining at least one of a payload and frame type () for at least one of a payload and frame () to be transmitted, and payload data pointers () into the memory ().

Abstract:

A lighting device assembly includes a heat sink, a light source attached to one end of the heat sink, an optic assembly to pivot an optic about the light source, and a housing member having a cavity in which at least a portion of the optic assembly is received and pivotally adjustable. An elastic member imparts a bias force on the optic assembly, to force an outer surface of the optic assembly against an inner surface of the housing member. The elastic member is held in a partially compressed state, to constantly impart the bias force on the optic assembly.
