Abstract: An apparatus and an associated method relates to a directionally polarized deceleration module (PDM) include a shuttle (125) fixedly coupled to a spring-biased spool (120) rotatable coupled to a module housing (115), a dynamic braking member (DBM) (130) and the shuttle (125) configured to travel inside a channel anchored to the module housing (115). A tether may be anchored on a proximal end to the spool (120). As the tether is retracted, the DBM (130) may be pushed by an angled distal-end of the shuttle (125). The DBM (130) may be forced between the angled distal-end of the shuttle (125) and an inner channel wall, providing motional resistance to the tether. As the tether is extracted, the DBM (130) may be pushed substantially normal to a proximal-end of the shuttle (125), providing minimal motional resistance to the tether. Various PDMs may decelerate safety lanyards in one direction to substantially avoid tangling and/or damage.

Abstract: The present invention relates to the field of elevator braking, in particular to an action state detection method and system for an elevator brake, comprising: acquiring matching pairs of brake linings in the same braking state; constructing normal record data sets based on the matching pairs; grouping the normal record data sets based on braking power corresponding to samples in the normal record data sets to determine a median of elevator running speed corresponding to the samples in each group; dividing the operating state levels of the elevator brake according to the size of the median; constructing a data training set; training a constructed network model to obtain a trained network model; acquiring the operating state levels of an elevator to be detected by the trained network model, evaluating the elevator brake according to the operating state levels, and controlling the elevator.

Abstract: Apparatus and associated methods relate to a smart hook, a safety harness module, and associated electronic components that detect a safety state of a user by monitoring various parameters at the smart hook and safety harness module and determining whether the user is using proper safety protocol at extreme heights and/or whether the user has experienced a height-related accident. In an illustrative example, the user may don a safety harness that may include a module that contains sensors that monitor an acceleration/velocity/position of the user and/or ambient air pressure around the user. The module may receive wireless signals from at least one rebar hook having sensors that monitor the acceleration/velocity/position and gate position of the rebar hooks. A controller included with the safety harness module may use these sensors to advantageously determine the safety state of the user and generate alert/warning signals.

Abstract: A harnesses for fall protection and methods of manufacturing the same are provided. The harness includes a horizontal connecting webbing with a force receiving mechanism. The horizontal connecting webbing including a first horizontal receiving loop at a first end of the horizontal connecting webbing. The harness also includes a first upper webbing configured with a upper webbing loop that is engaged with the first horizontal receiving loop at the first end of the horizontal connecting webbing. The harness further includes a first lower webbing configured with a lower webbing loop that is engaged with first horizontal receiving loop at the first end of the horizontal connecting webbing. The first upper webbing and the first lower webbing are independent of one another. A corresponding method of manufacturing the harness is also provided so as to withstand various large forces during operation.
