A plurality of modules interact to form an adaptive network in which each module transmits and receives data signals indicative of proximity of objects. A central computer accumulates the data produced or received and relayed by each module for analyzing proximity responses to transmit through the adaptive network control signals to a selectively-addressed module to respond to computer analyzes of the data accumulated from modules forming the adaptive network. Interactions of local processors in modules that sense an intrusion determine the location and path of movements of the intruding object and control cameras in the modules to retrieve video images of the intruding object. Multiple operational frequencies in adaptive networks permit expansions by additional networks that each operate at separate radio frequencies to avoid overlapping interaction. Additional modules may be introduced into operating networks without knowing the operating frequency at the time of introduction. New programs are distributed to all or selected modules under control of the base station.

A plurality of modules interact to form an adaptive network in which each module transmits and receives data signals indicative of physical properties sensed at the modules. A new module is joined in the adaptive network in an expedient manner. The new module transmits a burst of beacon messages after the interactive module is activated to discover neighboring interactive modules deployed and operating in the adaptive network. The neighboring interactive module stays in a sleep-mode of low-power expenditure. The beacon messages persist for a first interval longer than a second interval during which the neighboring interactive modules remain in the sleep mode. After receiving the beacon messages, one or more neighboring interactive modules transmit response messages to the new interactive module. The new interactive module receives the response messages and selects a neighboring interactive module for communication based on the received response messages. The new module can also include an indicator for indicating discovery of a neighboring interactive module with which a reliable wireless link can be established.

Remote modules operating as leaf nodes of the adaptive network actively adapt to changed network conditions upon awaking from power-conserving sleep mode.

A plurality of modules interact to form an adaptive network in which each module transmits and receives data signals indicative of the proximity of objects. A central computer accumulates the data produced or received and relayed by each module. One of the modules is operable as a leaf node having a sleep mode to conserve energy and an interactive mode. The central computer can send a message to the leaf node commanding it to stay awake in order to receive subsequent communications.

In one aspect, the present invention reduces the amount of low-latency memory needed for rules-based packet classification by representing a packet classification rules database in compressed form. A packet processing rules database, e.g., an ACL database comprising multiple ACEs, is preprocessed to obtain corresponding rule fingerprints. These rule fingerprints are much smaller than the rules and are easily accommodated in on-chip or other low-latency memory that is generally available to the classification engine in limited amounts. The rules database in turn can be stored in off-chip or other higher-latency memory, as initial matching operations involve only the packet key of the subject packet and the fingerprint database. The rules database is accessed for full packet classification only if a tentative match is found between the packet key and an entry in the fingerprint database. Thus, the present invention also advantageously minimizes accesses to the rules database.

Methods, apparatus, and systems for adaptive point cloud filtering for an autonomous vehicle are disclosed. At least one processor receives multiple LiDAR points from a LiDAR system. The multiple LiDAR points represent at least one object in an environment traveled by the vehicle. The at least one processor determines a Euclidean distance of each LiDAR point. The at least one processor compares the Euclidean distance of each LiDAR point with a respective sampled Euclidean distance from a standard normal distribution of Euclidean distances. Responsive to the Euclidean distance of a LiDAR point being less than the respective sampled Euclidean distance, the at least one processor removes the LiDAR point from the multiple LiDAR points to generate a point cloud. The at least one processor operates the vehicle based on the point cloud.

This disclosure describes one or more implementations of a digital image semantic layout manipulation system that generates refined digital images resembling the style of one or more input images while following the structure of an edited semantic layout. For example, in various implementations, the digital image semantic layout manipulation system builds and utilizes a sparse attention warped image neural network to generate high-resolution warped images and a digital image layout neural network to enhance and refine the high-resolution warped digital image into a realistic and accurate refined digital image.
