Abstract: A system and a method are disclosed for providing recommendations for sets of security operations for improving security of documents created or executed within an online document system. A supplier entity may select sets of security operations to be performed for a request provided to a signing entity. The online document system computes an aggregate measure of security for the selected sets of security operations and compares it to a threshold measure of security. If the aggregate measure is less than the threshold measure, the online document system uses a machine-learned model to identify additional sets of security operations that when added, results in an updated aggregate measure of security greater than the threshold. The additional sets of security operations are presented to the supplier entity for inclusion within a security operation workflow in combination with the selected sets of security operations.

Abstract: A cargo bicycle having at least a frame, rear wheel, and rear carrier rack, comprising a rear safety cage, pair of footboards and passenger cabin having a canopy and box is provided. The rear safety cage is mounted to the frame. The passenger cabin is mounted to the rear safety cage, rear carrier rack and pair of footboards and forms an interior passenger space for accommodating passengers and protecting passengers from natural or human-made environmental elements. The canopy forms an upper interior space. The box forms a lower interior space and a pair of lower interior side spaces extending outwardly from the lower interior space, straddling the rear wheel. Each of the pair of lower interior side spaces is a self-contained vessel, further protecting lower extremities of passengers from components of the cargo bicycle and debris during operation of the cargo bicycle.

Abstract: The bicycle which includes a rear wheel and a frame is disclosed. The frame includes a frame main body and two first supporting platforms. The frame main body includes two supporting parts, a bottom frame and a surrounding part. The two supporting parts are respectively located on the two sides of the rear wheel. The bottom frame is located in front of the rear wheel. The surrounding part is located in back of the rear wheel. The two first supporting platforms are respectively located on the two sides of the rear wheel. Each of the two first supporting platforms includes a side plate and a top plate. The side plate includes a front connecting end and a back connecting end.

Abstract: A trolley-like folding bicycle that mainly includes a bicycle frame, a folding device, a transmission gear, a draw bar, and a draw wheel set is disclosed. With the operation of the folding device, the present invention has a usage state and a folded state. When the present invention is in the folded state, the user can draw the trolley-like folding bicycle by simply turning the folded bicycle body upright such that the draw wheel set contacts the ground and then pulling the draw bar. At this stage, an axis formed with the draw bar is substantially perpendicular to a draw rotation axis formed with small wheels of the draw wheel set. The user can move the trolley-like folding bicycle by simply pulling the draw bar, as easily as drawing a luggage case.
