Title: High-speed programmable packet scheduler and buffer manager
Inventor: LEON-GARCIA ALBERTO
IPC: H04L12/863
Filed: 1999-11-24
Abstract: A method and apparatus for managing the buffering and for scheduling the transfer of packets of data arriving on one or a plurality of input ports and destined for one or a plurality of output ports of a packet switch or router or a subsystem thereof is disclosed. Each arriving packet is assigned an index that specifies both a unique destination output port for the packet and membership in a subclass, such as a priority class, a connection or flow, or a class of packets that is to receive a certain type of transmission or buffering service. For each arriving packet, a minipacket is created that contains the index of the packet, a unique identifier such as a storage location, and optionally information relevant to the scheduling and buffering of the packet. Each index is assigned a unique queue in which minipackets with the given index are placed in order of arrival. A method and apparatus for a scheduler and buffer manager is disclosed that: maintains a large number of said queues; identifies the head-of line minipackets from said queues to a head-of line sequencer ; selects the order in which minipackets are output according to a scheduling algorithm. Packets are transmitted from storage to output ports according to the sequence of minipackets that exit the scheduler system. The disclosed scheduler is flexible and can be programmed to implement various scheduling algorithms, including weighted fair queuing, priority queuing, hierarchical fair queuing and all variations that involve sorting according to a tag value. The disclosed scheduler is scalable in that it can provide individual queues for a very large number of port/subclass combinations. The disclosed scheduler can be implemented in integrated circuits to operate at very high speeds.

Inventor: KIM JE WOO
IPC: H04W88/00
Filed: 1999-05-12
Abstract: L'invention concerne un dispositif et un procédé destinés à réduire le rapport puissance de crête/puissance moyenne de la puissance d'émission d'une station mobile dans un système de communication mobile, lequel procédé consiste à étaler et à moduler les données d'émission au moyen d'une séquence d'étalement complexe. Cette séquence d'étalement complexe est générée de manière à présenter une pluralité de microblocs et une différence de phase de 90· entre deux microblocs complexes successifs en réponse à chaque microbloc d'une séquence de pseudo-bruit. Ce dispositif et ce procédé permettent de commander de façon souple la puissance d'émission de la station mobile par limitation du rapport puissance de crête/puissance moyenne à une plage déterminée, et donc par confinement de la puissance d'émission de la station mobile à une partie caractéristique linéaire de la courbe caractéristique d'un amplificateur de puissance. On empêche ainsi la phase de la séquence d'étalement complexe de tourner de 180· (soit .pi.) pour maintenir la puissance d'émission de la station mobile dans la partie linéaire de la courbe caractéristique de l'amplificateur de puissance.

Patent CA-2307372-A1 (CA)
Inventor: STEED MICHAEL A
IPC: D06F39/02
Filed: 1998-10-08
Abstract: A chemical dispensing system controller is used in conjunction with a mechanism for dispensing specified chemicals and a device that transmits trigger signals to the control system for requesting chemicals to be dispensed. The controller receives and accumulates sequences of the transmitted trigger signals. Each trigger signal sequence is preceded and followed by a period of time of predefined duration during which no trigger signals are received. At least some of the trigger signals in some of the trigger signal sequences are not received simultaneously. Also, the number of distinct chemical feed requests that can be communicated using the accumulated trigger signals exceeds the number of distinct trigger signals. The controller maps a first subset of the accumulated trigger signal sequences into chemical feed requests, each of which requests a quantity of a corresponding chemical. The controller enables the dispensing of chemicals in accordance with the chemical feed requests. A second subset of the accumulated trigger signal sequences are mapped into wash classification codes, each of which identifies a type of wash load to be washed using the dispensed chemicals. The number of distinct wash classification codes that can be communicated using the accumulated trigger signals exceeds the number of distinct trigger signals. When the control system uses a classification dependent feed arrangement, the chemical feed request corresponding to each received trigger signal sequence is determined based on both the current wash load type and the accumulated sequence of trigger signals.

IPC: G06K17/00
Filed: 1999-03-03
Abstract: An identification system is provided for identifying a plurality of object-based transponders (14, 16, 18, 20) using an interrogator (10). The interrogator (10) includes a transmitter for transmitting an interrogation signal to the transponders, a receiver for receiving identification signals from the transponders, and processor means (21) for determining the individual and connect receipt of an identification signal. The transponders operate on the basis of backscatter modulation, and include a detector for detecting the presence of an interrupt signal from the interrogator. Control logic responsive to the detector is arranged to cease signal transmission from the transponder if the transponder completes transmission of the identification signal without receiving an interrupt signal during such transmission. The interrogator (10) is arranged to receive the identification signals from the transponders (14, 16, 18, 20) and substantially contemporaneously to determine if any identification signal has been individually and correctly received. In the event of any identification signal not being individually and correctly received, the interrogator (10), at substantially the same time, transmits a common interrupt signal for temporarily suspending signal transmission from the transponder (14) if the transponder is transmitting its identification signal at the time it receives the interrupt signal. The transponder (14) independently ceases signal transmission if it completes transmission of an identification signal without receiving an interrupt signal.
