摘要： A method controls multicast cell access to a switching network with a reservation ring in an ATM (Asynchronous Transfer Mode) switch. The switching network distributes the multicast cell in one or more passes from an input channel to one or more output channels of the switch during a switch cycle. An arbitration session for a multicast cell begins by submitting an arbitration request identifying a set of destination output channels to the reservation ring. During an arbitration cycle, the output channels in the set of destination output channels are arbitrated for over the reservation ring. The arbitration request is reissued during later arbitration cycles until access to each of the destination output channels in the set of output channels is granted.

摘要： A self-arbitrating and self-routing ATM (Asynchronous Transfer Mode) switch has a switching fabric consisting of rows and columns of logic groups. The rows of logic groups have addressing logic for routing data packets received at input ports to the columns of logic groups. Arbitration logic in each of the columns of logic groups route data packets received from the addressing logic to their specified output ports. The arbitration logic forming each column of logic groups resolves conflicts between data packets contending for an identical output port. Additional logic in each column of logic groups signals input ports when data packets are successfully received by their specified output ports. Data packets which lose arbitration during a switch cycle are assigned a higher priority and retransmitted to the switching fabric during the next switch cycle.

摘要： A crossbar switching fabric for routing data packets in an ATM switch. A logic unit associated with a reservation ring in an ATM switch intercepts data exiting a selected evaluator of the reservation ring, and processes this data to set-up a crossbar switching fabric for routing data packets of the ATM switch. The set-up data may be passed to the crossbar switching fabric upon each clock cycle thereby not incurring any pipeline processing delays. Alternatively, the set-up data is accumulated and stored in the logic unit until the completion of an arbitration session, whereafter it is sent to the crossbar. In place of the logic unit a plurality of registers may be added to each of the evaluators of the reservation ring. The registers in turn interconnected to each other in a shift register arrangement to provide the set-up data to the crossbar fabric.

摘要： A switching network having a sorting network followed by a plurality of routing networks for routing packets from a plurality of inputs to a plurality of outputs in accordance with destination addresses specified by the packets includes a reservation ring mechanism for resolving conflicts among inputs contending for access to identical outputs. This reservation ring mechanism performs a sequence of step and compare operations in top-to-bottom ring-like order during one or more arbitration cycles for granting contending inputs access to the outputs for which those inputs are contending in top-to-bottom order. Each of the routing networks can route packets from any input to any output, so up to k packets are routed to each output during each arbitration cycle, where k equals the number of routing networks that are employed.

摘要： Access to a limited bandwidth switching network of an ATM (Asynchronous Transfer Mode) switch is scheduled using a reservation ring. In general, a limited bandwidth switching network is unable to generate all possible one-to-one input to output channel mappings in a single switch cycle. The limited bandwidth switching network includes one or more routing channels for routing at most B data packets each switch cycle between the input channels and output channels, where the number of data packets B is less than the aggregate output bandwidth that can be directed at the routing channels. Arbitration requests make two passes around the reservation ring each arbitration cycle. Output channel contention is settled during the first pass around the reservation ring. Contention for limited switching network bandwidth is settled during the second pass around the reservation ring. Arbitration requests granted a reservation at the end of an arbitration cycle are issued into the limited bandwidth switching network during a subsequent switch cycle.

摘要： Ports of an ATM (Asynchronous Transfer Mode) switch are consolidated into cluster modules to increase the aggregate throughput of the switch. Packets are routed between cluster modules using an intercluster switching network. The intercluster switching network includes a plurality of input channels and output channels. During a switch cycle, a maximum of "K" packets are delivered to each of the output channels of the intercluster switching network. This maximum of "K" packets is a speedup per cluster module that is shared between ports of each cluster module. Consequently, each output port of a cluster module operates with a peak speedup of up to "K" packets per switch cycle thereby increasing the aggregate throughput of the switch.

摘要： A method for detecting chemical reactions uses a nanocalorimeter having a substrate including thermal isolation capability residing on the substrate, thermal equilibration regions residing within the thermal isolation capability, and thermal measurement capability residing within each of the thermal equilibration regions. The thermal measurement device is connected to detection electronics. The method includes depositing drops of potentially reactive chemical solutions within the thermal equilibration region. These potentially reactive solution drops are merged through the use of drop merging electrodes residing within the thermal isolation region. The thermal change occurring within the merged solution drops is then measured with the detection electronics.

摘要： Access to a switching network of an ATM (Asynchronous Transfer Mode) switch is scheduled with a reservation ring that automatically determines the number of channels populating the switching network during a switch cycle. The reservation ring is a distributed arbiter that resolves conflicts arising among a plurality of input channels for access to a plurality of output channels of the switching network. Each input channel populating the switching network is coupled to an arbitration unit of the reservation ring. The arbitration units on the ring determine when an arbitration cycle is complete for each of the arbitration units populating the ring. This enables the number of channels populating the switching network to increase or decrease without having to reconfigure the reservation ring.

摘要： A computer-implemented system and method for providing gun shot detection through a centralized parking services server is provided. Smart parking devices are physically proximate parking spaces. Acoustic sensors are deployed with at least one acoustic sensor in a smart parking device. Vehicle occupancy sensors and parking availability indicators are associated with the parking spaces. Parking space occupancy is sensed through the nearest vehicle occupancy sensor. Use of the parking space is processed based on an identity of a driver. Potential gunshots are detected by aurally monitoring ambient sounds in the service region through the acoustic sensors. The potential gunshots are identified by evaluating the ambient sounds for sound characteristics of gunfire and triangulating the ambient sounds relative to the locations of the acoustic sensor comprised in one of the smart parking devices and at least one other of the acoustic sensors. Finally, an alert is generated for the potential gunshot.
