摘要:
A Lidar measurement device for vehicular traffic surveillance and method for use of same are disclosed. In one embodiment, video circuitry acquires video of a field of view having a target therein. A steerable laser progressively scans the field of view to identify targets. The steerable laser then progressively, repeatedly scans a sub-field of the field of view containing the target. A processing circuit portion determines target data of the target based upon range and time measurements associated with reflected laser range-finding signals from the scans of the sub-field. The processing circuit then integrates the target data into the video such that the video may displayed with an image of the target and target data, such as a speed measurement, associated therewith.

A memory card cooperating with a network interface for receiving data entry and update signals from a database manager via a switch fabric and with a bus interface for outputting data on a system bus disposed in a system shelf, which shelf forms at least a portion of a telecommunications node having a distributed scalable database system. The memory card is operable to contain at least a portion of the distributed database in a high speed, high density memory block disposed thereon, which memory block is coupled to a network interface controller via a first memory interface and to a bus interface controller via a second memory interface. An arbiter is coupled to the first and second memory interfaces for arbitrating data input operations and data output operations with respect to the memory block.

A bus control module for a delivery unit, which interfaces an optical fiber network to a switching matrix. The bus control module controls transport of control data and network data between various application modules of the delivery unit. The control data and network data are carried as datagrams on ingress links from the application modules and on egress links to the application modules.
摘要:
A series of police doppler single mode radars and a multimode police doppler radar, all with direction sensing capability are disclosed. A quadrature front end which mixes received RF with a local oscillator to generate two channels of doppler signals, one channel being shifted by an integer multiple of 90 degrees in phase relative to the other by shifting either the RF or the local oscillator signal being fed to one mixer but not the other. The two doppler signals are digitized and the samples are processed by a digital signal processor programmed to find one or more selected target speeds. Single modes disclosed are: stationary strongest target; stationary, fastest target; stationary, strongest and fastest targets; moving, strongest, opposite lane; moving, strongest, same lane; moving, fastest, opposite lane; moving, fastest and strongest, opposite lane; moving, fastest, same lane; moving fastest and strongest, same lane.
摘要:
A police radar utilizing digital data transmission from the antenna unit to a separately housed counting and display unit. The antenna has a double balanced mixer to suppress even order harmonics. The counting and display unit has a computer programmed to perform digital signal processing on the digital data received from the antenna to improve the quality and accuracy of calculated speeds for patrol speed, strongest target speed and fastest target speed. Fastest target speed can be displayed simultaneously with strongest target speed. Signal processing techniques are used to suppress false signals caused by double and triple bounce, harmonics, intermodulation products, video display terminal interference, etc.

A system, method, and computer readable medium for time stamp offset in data packet bundling including filling a globally distributed time stamp based upon a globally distributed time, receiving a signal unit, resolving a difference in time between the globally distributed time stamp and the reception of the signal unit and assigning a time offset based upon the resolved time difference.
摘要:
An enhanced police Doppler direction sensing radar detects possibly dangerous traffic conditions during certain vehicle maneuvers such as U-turns and returns to travel after roadside stops. By monitoring a host or primary vehicle speed, speed transitions, transmission state (e.g. gear selection), and the closing vehicle position, range and speed, a number of selectable conditions are detected, resulting in an alert indication to a primary vehicle operator. User preferences and thresholds allow the traffic alert function to be customized according to a primary vehicle operator's desire to suppress alerts in situations which the user does not deem dangerous. The traffic alert function may be automatically triggered under certain detected conditions, or manually initiated when the primary vehicle operator intends to make a driving maneuver.
摘要:
A system and method for personalizing a generic state machine (GSM) logic structure in order to effectuate individual protocol layer functionality of a high speed link protocol stack at a network node (i.e., an application node) having a plurality of connections. An input event structure including at least a service access point (SAP) and a connection identifier (CID) associated with a select service provider layer is provided to a context switch and control block that is operable to retrieve latest state-specific context information based on the SAP and CID. The GSM logic structure is personalized based on the context information to effectuate appropriate service provider layer functionality. The input event is processed by the personalized GSM logic structure to generate next-state information and an output event vector including SAP/CID data for specifying appropriate destinations (i.e., one or more service user layers).
摘要:
A signaling link interface (10) includes a high level data link controller (12) that receives signaling information from network elements in a telecommunication network. A link state controller (14) performs message transfer part level two processing on the signaling information. The link state controller (14) generates a response message that the high level data link controller (12) provides back to the network elements. The high level data link controller (12) and the link state controller (14) are implemented in hardware as field programmable gate array devices. Information related to operation of the signaling link interface (10) may be downloaded from a remote site into the field programmable gate array devices. The signaling link interface (10) processes signaling information received from a plurality of signaling links on a link by link basis.
