Abstract: The resent disclosure provides a treadmill, including a chassis, stand columns mounted at both sides of the chassis, a deck rotatably mounted on the chassis and configured to rotate relative to the chassis to a longitudinal direction or a horizontal direction, a handrail assembly rotatably mounted on the stand columns and configured to rotate relative to the stand columns to a folded state or an unfolded state, and a controller configured to control rotation of the deck and the handrail assembly. The controller is configured to control the deck to rotate to the longitudinal direction when the controller controls the handrail assembly to rotate relative to the stand columns to be in the folded state, and control the handrail assembly to rotate relative to the stand columns to be in the unfolded state when the controller controls the deck to rotate from the longitudinal direction to the horizontal direction.

Abstract: An interactive display system includes a display device and a user device. The display device includes a controlling unit and lighting units, and the controlling unit transmits a color signal to the lighting units. When the user device emits an active light signal to the lighting units, the lighting unit that receives the active light signal lights up according to the color signal. Namely, when the user uses the user device to emit the active light signal to the lighting units of the display device, the lighting units illuminated by the active light signal can light up. Therefore, the user can use the display device as a canvas, and the user can draw a picture or write a memo on the display device for interacting with the display device of the interactive display system.

Abstract: A motion tracking system for tracking the motion of a subject in an environment, the system comprising: an imaging device adapted to be worn by the subject; an accelerometer adapted to be worn by the subject; and a processor configured to receive a series of images of the environment captured by the imaging device and to form, in dependence on the images an estimate of the subject's position in the environment, and to receive acceleration data from the accelerometer and to, form an estimate of the motion of a part of the subject's body carrying the accelerometer in dependence on the acceleration data and the estimated position.

Abstract: A transaction card system pulls past transaction data from a financial institution. A user profile model is applied to the past transaction data and customer data features and transforms the data into a user feature profile that summarizes the identity data, financial health and payment capacity of the customer. An overdraft request has current declined transaction details relating to a customer transaction using the transaction card. The computing network pulls from cache the most recent customer transaction banking data and most recent user feature profile and applies a machine learning approval model to the current declined transaction details, the most recent customer transaction data, and the most recent user feature profile, and determines whether to approve or decline the overdraft amount.

Abstract: A method, apparatus, and article of manufacture for collecting and exchanging data are disclosed. In one embodiment, the apparatus comprises a non-volatile memory device, which includes an interface for coupling the non-volatile memory device to a host system; non-volatile memory for storing data, including a plurality of executables at least two of which are executable on different operating systems or devices. The plurality of executables includes a data collection executable and a data transfer executable. The nonvolatile memory device also includes a controller to cause execution of at least one executable in the plurality of executables, including the data collection executable and the data transfer executable, where execution of the data collection executable causes data to be collected and stored in the non-volatile memory, and execution of which causes the collected data to be transferred to a location external to the non-volatile memory device.

Abstract: Apparatuses, methods and infrastructures for interacting with SNDs and SLANs are described.
