Methods and apparatus for monitoring a dock leveler are disclosed herein. One example dock leveler system for use at a doorway of a loading dock, where a body is sometimes present at the loading dock, includes a deck movable between a raised position and a lowered position. The example dock leveler system also includes a sensor having a field of view extending over the deck when the deck is in the lowered position. The sensor is in a normal state when the deck is in the lowered position while the body is off the deck, the sensor is in a triggered state when the deck is in the lowered position while the body is on the deck interrupting the field of view, and the sensor is in the triggered state when the deck is in the raised position with the deck interrupting the field of view regardless of whether the body is on or off the deck.
Cache memory mapping techniques are presented. A cache may contain an index configuration register. The register may configure the locations of an upper index portion and a lower index portion of a memory address. The portions may be combined to create a combined index. The configurable split-index addressing structure may be used, among other applications, to reduce the rate of cache conflicts occurring between multiple processors decoding the video frame in parallel.
Systems and methods for detection of domain generated algorithms (DGA) and their command and control (C&C) servers are disclosed. In one embodiment, such an approach includes examining DNS queries for DNS resolution failures, and monitoring certain set of parameters such as number of levels, length of domain name, lexical complexity, and the like for each failed domain. These parameters may then be compared against certain thresholds to determine if the domain name is likely to be part of a DGA malware. Domain names identified as being part of a DGA malware may then be grouped together. Once a DGA domain name has been identified, activity from that domain name can be monitored to detect successful resolutions from the same source to see if any of the successful domain resolutions match these parameters. If they match specific thresholds, then the domain is determined to be a C&C server of the DGA malware and may be identified as such
A machine may be configured to generate one or more audio fingerprints of one or more segments of audio data. The machine may access audio data to be fingerprinted and divide the audio data into segments. For any given segment, the machine may generate a spectral representation from the segment; generate a vector from the spectral representation; generate an ordered set of permutations of the vector; generate an ordered set of numbers from the permutations of the vector; and generate a fingerprint of the segment of the audio data, which may be considered a sub-fingerprint of the audio data. In addition, the machine or a separate device may be configured to determine a likelihood that candidate audio data matches reference audio data.
The ornamental design for a chair back, substantially as shown and described.
Methods, apparatus, and articles of manufacture to identify non-uniformity in a vehicle steering system are disclosed. An example apparatus includes a first sensor to measure a steering wheel angle relative to a first universal joint, a second sensor to measure a pinion angle relative to a second universal joint, and a third sensor to measure a torque relative to a torsion bar. The apparatus further includes a non-uniformity manager to determine a non-uniformity angle associated with a steering column, the non-uniformity angle based on the torque and comparing the steering wheel angle to the pinion angle, map the non-uniformity angle to a first position of the steering column, and determine an offset to adjust a steering response based on the first position.
Methods and apparatus to monitor work vehicles and to generate worklists to order the repair of such work vehicles should a machine failure be identified are disclosed. An apparatus includes an interface to access a first and second alerts from first and second work vehicle; an alert scorer to generate first and second scores for the respective first and second alerts; a machine health score determiner to determine first and second machine health score for the respective first and second work vehicles based on the first score and the first weighting factor and the second score and the second weighting factor; and a worklist generator to generate a worklist indicating that the second work vehicle is to be repaired prior to the first work vehicle based on at least one of the first and second machine health scores or an associated first and second classifications.
Methods and apparatus of modeling work vehicle data and predicting machine failures based on the same are disclosed . An example method includes accessing a first alert sequence from a work vehicle , the first alert sequence is associated with one or more of observed diagnostic code , observed vehicle sensor data , or observed vehicle status data ; comparing the first alert sequence to a model including an association between reference alert sequences , reference machine failures , and probable parts used to repair the respective reference machine failures ; identifying a substantial similarity between the first alert sequence and a first reference alert sequence of the reference alert sequences; and based on the model and the first reference alert sequence , identifying first probable parts of the probable parts used to repair a first reference machine failure of the reference machine failures , where the first reference machine failure is associated with the first reference alert
An example system disclosed herein includes an analyzer to determine a first priming characteristic of media at a first location based on first neuro-response data and determine a second priming characteristic of the media at the second location based on second neuro-response data. The example system includes a selector to select a third location in the media after the first location or a fourth location in the media after the second location as a candidate location for introduction of advertising material based on the first priming characteristic and the second priming characteristic. The selector is to select the third location when the first priming characteristic indicates increased receptivity to the advertising material at the first location relative to the second priming characteristic and select the fourth location when the second priming characteristic indicates increased receptivity to the advertising material at the second location relative to the first priming characteristic.
Apparatus and methods for controlling architectural opening coverings are described herein . An example apparatus includes a roller tube , a motor including a motor drive shaft and a motor casing , the motor casing to rotate with the roller tube , and a manual control including a manual control drive shaft coupled to the motor drive shaft , the motor to apply torque to the roller tube through rotation of the motor casing.
