Abstract: A height safety trolley and modular rigid rail system for construction and maintenance personnel working at height is designed to allow continuous, smooth and fail-safe operation, for fall restraint and fall arrest, rope access and abseil. The height safety trolley has a connection arm, a clip body and a main chassis operably interfacing a rail engagement mechanism, movable between a rail engagement position to engage a rigid rail, and a disengagement position to disengage the rigid rail. The rail engagement mechanism may comprise integral pivot arms which close simultaneously inwards to engage the rigid rail and outwards to disengage the rail. As such, the trolley is easily and safely attachable and detachable at any position along the rigid rail.

The controller is configured to authenticate the control signal, wherein authenticating the control signal includes associating the signal with a first level of access or a second level of access. The controller is further configured to communicate with the door lock via the communication circuitry to permit opening of the passageway door in response to associating the control signal with the first level of access and inhibit opening of the passageway door in response to associating the control signal with the second level of access. The controller is configured to cause the motor to open the movable barrier regardless of association of the control signal with the first level of access or the second level of access.

Abstract: A push notification mechanism at a mobile user device provides for automated limiting of the rate of production of push notification alerts (such as an audible alert or a vibratory alert) and/or push notifications responsive to the occurrence of chat events relevant to a chat application hosted by the user device.

Abstract: Systems and methods are disclosed that relate to freespace detection using machine learning models. First data that may include object labels may be obtained from a first sensor and freespace may be identified using the first data and the object labels. The first data may be annotated to include freespace labels that correspond to freespace within an operational environment. Freespace annotated data may be generated by combining the one or more freespace labels with second data obtained from a second sensor, with the freespace annotated data corresponding to a viewable area in the operational environment. The viewable area may be determined by tracing one or more rays from the second sensor within the field of view of the second sensor relative to the first data. The freespace annotated data may be input into a machine learning model to train the machine learning model to detect freespace using the second data.
