Abstract: A computer implemented method for managing the scope of permissions granted by users to application that includes collecting a set of permissions for an application from an application provider publication; and collecting a process flow for functional steps of the application from a review of the application that is published on a product review type publication. The computer implemented method further includes dividing the functional steps of the application into a plurality of journeys, each of said plurality of journeys having a function associated with a stage of a functional step from a perspective of a user; and matching permissions from the set of permissions for each journey of said plurality of journeys to provide matched permissible permissions to journeys stored in a customer journey store.

Abstract: A treadmill with a safety warning function includes a miming unit, a driving unit, a detection unit and a control unit. The running unit includes a driving roller and a running belt provided for a runner to stand thereon. The detection unit includes a camera arranged at a predefined height range on top of the running belt for photographing images. The control unit determines a height of the runner based on the images photographed. The safety monitoring method for the treadmill includes obtaining an image above the running belt and determining whether the height of the runner is greater than the predefined height. By determining whether the height of the runner is greater than the predefined height, it is able to determine whether the driving roller can be driven by the driving unit to rotate, thereby preventing the hazard of accidental activation by a child of insufficient height.

Abstract: A treadmill with a safety monitoring function includes a running unit and a detection unit. The running unit includes a driving roller and a running belt for a runner to stand and run thereon. The detection unit includes a sensor for detecting whether the runner exists at a predefined height on the running belt. The detection unit can be moved to change the predefined height. A safety monitoring function for a treadmill includes adjusting a height of the sensor, detecting whether the runner exists at the predefined height above the running belt, and generating a first monitoring output. Through detecting whether the runner exists at the predefined height, it determines whether the driving roller can be driven by the driving unit to prevent accidental activation by a child. Since the detection unit can be moved to change the predefined height, it allows the use by runners of different body shapes.

Abstract: A backrest device comprises at least one backrest and at least one connecting unit having two springs, two jointing members and a connecting member. Each spring comprises a first end and a second end. Each jointing member is provided with at least one first engaging block for engaging with the first end of the spring. The connecting member is provided with at least one second engaging block for engaging with the second end of the spring and is fixed to a chair stably. When the user sits in the chair with his back leaning against the backrest, since the springs are flexible, which can enable the backrest to be freely adjusted and moved in response to the movement of the back of the user, producing a buffering effect and providing a comfortable support to the back of the user, so the user will feel comfortable.

Abstract: A movable backrest for a chair comprises a frame that is fixed to the chair, at least a flexible connecting element connected to the frame, and at least a backrest connected to the connecting element. Since the connecting element is flexible, the backrest and the back of the user can be moved simultaneously along with the movement of the back of the user, providing a comfortable support to the back of the user.
