A video monitor support movable between stowed and deployed positions includes a base attachable to a surface and a carriage fixed to the base. The carriage includes a shaft extendible between the stowed and deployed positions. A constant linear force is applied to the shaft between the stowed and deployed positions, and a mount is fixed to the shaft opposite the carriage for supporting a video monitor.

Throttles electronic devices based on compliance with rules for electronic communications such as emails, texts, or postings on social media sites. Rules may for example prohibit certain topics, language, or behaviors such as online bullying. If system detects a violation of the electronic communications rules, it may block access or reduce performance on one or more electronic devices as a consequence. In some cases, devices or selected apps or services may continue to function, but at a reduced level. Conversely the system may provide rewards for conforming with the rules. Throttling of devices may also depend on other factors, such as homework completion, test results, grades, and environmental conditions. Machine learning techniques may be applied to determine when electronic communications may violate the rules. For example, probabilistic topic models may be applied to determine the topics of electronic communications, and to assess whether these topics violate the rules.

The invention discloses a deep feature and transfer learning-based rolling bearing fault diagnosis method under variable working conditions, relates to the technical field of fault diagnosis, and aimsto solve the problem of low state identification accuracy of different fault positions and different performance degradation degrees of a rolling bearing under the variable working conditions. The method comprises the following steps: firstly, carrying out feature extraction on the vibration signal frequency domain amplitude of the rolling bearing by adopting SDAE to obtain vibration signal deepfeatures, and forming a source domain feature sample set and a target domain feature sample set; then, adopting the JGSA to carry out domain adaptation processing on the source domain feature sample and the target domain feature sample, the purpose of reducing distribution offset and subspace transformation difference of feature samples between domains is achieved, and domain offset between different types of feature samples is reduced. And finally, completing rolling bearing multi-state classification under variable working conditions through a K nearest neighbor algorithm. Compared with other methods, the method disclosed by the invention shows better feature extraction capability under the variable working condition of the rolling bearing, the sample feature visualization effect of therolling bearing is optimal, and the fault diagnosis accuracy of the rolling bearing under the variable working condition is high.

A pest bait station includes a disposable carrier disposed in a reusable housing. Pest bait is securely affixed to the carrier such that movement of the station does not dislodge the bait from the carrier. A first bait affixed to a lower surface of the carrier exterminates smaller pests while a second bait affixed to an upper surface of the carrier exterminates larger pests. The carrier is shaped, such as a cone, to provide a lower space and an upper space for receiving differently sized pests. A lid of the housing is shaped to accommodate the shape of the cone. The lid is removably coupled to a base to form a water-tight seal. Openings formed in the base allow for entry of pests. A magnet or adhesive may be placed on a bottom side of the base to enable the station to be coupled to any surface.

The invention discloses a method for prolonging the service life of a solid-state disk, which comprises the following steps of: (1) adding a write request into a write request queue in a buffer area of a solid-state disk; (2) selecting a data page in the write request as a sampling page; (3) calculating the fingerprint of the sampling page and also comparing with fingerprints in a fingerprint library so as to carry out matching; (4) if no matching fingerprint is found, writing the rest data pages in the sampling page and the request into a flash memory of the solid-state disk directly; and (5) if a matching fingerprint exists, carrying out fingerprint calculation on each of the rest pages respectively and also comparing with the fingerprints in the fingerprint library respectively so as to carry out matching: updating a corresponding mapping table directly for the data page in which the matching fingerprint is found and writing the data page in which the matching fingerprint is found into the solid-state disk. According to the method for prolonging the service life of the solid-state disk, the actual physical occupation of data in the solid-state disk on the flash memory is reduced, the redundant space of a system is indirectly increased, and the frequency of the garbage recovering operation of the system is reduced, so that the service life of the solid-state disk is enhanced.
