Abstract: An inventory management system for maintaining inventory of liquid containers. A first container storage device, in a stock room weighs bottles and gets unique IDs on the bottles. A second device also weighs and reads information in a bar area. A database stores identification information and weights from the first and second container storage device, and operating to determine when a first container has been lifted from said first container storage device and moved to said second container storage device. The database indicates the first container as being in storage when the first container is on said first container storage device and indicates the first container as being in use when the first container when the first container is on said second container storage device. When the weights differ, the computer indicates an incident.

Abstract: A drink ordering and dispensing system. A drink is ordered, and placed into a database. When drinks are poured, they are associated with the drinks that have been in the database. Scale is used to hold all the bottles. Whenever a bottle is removed or replaced on the scale, the total weight of the scale changes, and hence the weight change of the bottle can be determined. Once the drink is poured, the id of the bottle, and the weight on the scale before and after pouring is used to determine if the drink has been over poured. The scale includes a camera that can be used to identify the bottle and the server who does the pouring. The server who does the pouring can be identified using a biometric scan of the person, obtained using the same camera that identifies the bottle being poured.

Abstract: Methods and structures are presented for implementing an automatic target recognition system as a convolutional neural network (CNN) in a satellite or other environment with constrained resources, such as limited memory capacity and limited processing capability. For example, this allows for the automatic target recognition to be implemented on a field programmable gate array (FPGA). Image data is split into subsets of contiguous pixels, with the subsets processed in parallel in a CNN of a corresponding processing node using quantized weight values that are determined in a training process that accounts for the constraints of the automatic target recognition system. The results of the automatic target recognition process is based on the combined output of the processing nodes.
