Abstract: In described examples, a circuit includes a system bus controller having a first downstream port and is configured to generate a first downstream frame responsive to a first local bus transmission received by a first local bus controller, and to generate a second downstream frame responsive to a second local bus transmission received by a second local bus controller. The system bus controller is configured to generate a downstream aggregate frame responsive to the first downstream frame and the second downstream frame and is configured to initiate transmission of the downstream aggregate frame at the first downstream port. The system bus controller is adapted to receive an upstream aggregate frame that includes a first upstream frame and a second upstream frame and is configured to generate a first upstream transmission responsive to the first upstream frame and to generate the second upstream transmission responsive to the second upstream frame.

Abstract: In this nonprovisional utility patent application, we describe a system and method for enabling micro check-in, which is defined as the process by which a user can selectively reveal her location at a service point in order to obtain specific services from a service provider. The invention is characterized by three unique, novel, traits: (a) the check-in (location revelation) happens at a fine resolution not possible by GPS-based sensors, (b) definition of specific service points, and (c) provision of a service or utility at the service point or elsewhere by the service provider. This represents the novelty of the invention with respect to the prior art, and also allow several new uses described in this application. In one embodiment we describe a system and method for ordering food from a restaurant table using a smartphone. We also describe several other embodiments for a variety of domains.
