A tray assembly for monitoring food consumed from one or more dishes supported by the tray assembly includes a housing defining an interior and having an upper surface for supporting the one or more dishes. One or more weight assemblies are disposed in the interior of the housing. Each weight assembly includes a weight sensor configured to detect a weight of one dish of the one or more dishes and to provide a weight signal corresponding to the detected weight of the one dish. A difference between the weight taken at a first time during a meal and at a second time, after the first time, during the meal being generally indicative of an amount of food consumed during the meal from the one or more dishes.

A product transfer enclosure comprising: a back door assembly; a front door assembly; an electronics module comprising a communication chip for enabling data communication over a network; and a display screen, coupled to the front door, for displaying dynamic messages based on the data communication.

Barcode readers with off-platter detection assemblies are disclosed herein. An example barcode reader includes a weigh platter and an off-platter detection assembly including a light emission assembly, a light detection assembly, and a controller. The light emission assembly emits a light along a first lateral edge of the weigh platter and the light detection assembly detects at least a portion of the light from the light emission assembly. The controller is configured to: receive a light detection signal from the light detection assembly; compare the light detection signal to a first signal threshold and a second signal threshold range; execute a first event if the light detection signal is less than the first signal threshold, indicating an off-platter event; and execute a second event if the light detection signal is within the second signal threshold range for a predetermined period of time, indicating a maintenance event.

A weigh platter assembly includes a weigh platter having a proximal edge and a lateral edge and an off-platter detection assembly. The off-platter detection assembly has an assembly field-of-view (field-of-view) extending from the proximal edge and constrained to have an assembly central field-of-view axis substantially parallel to the lateral edge and at least one lateral boundary substantially adjacent to the lateral edge. A light emission assembly has a light source and emits a light away from the proximal edge. A light detection assembly has a light sensor and detects at least a portion of the light reflected towards the proximal edge. A controller allows the measured weight to be recorded in response to a first value from the light detection assembly and prevents the measured weight from being recorded and/or provides an alert in response to a second value from the light detection assembly.

The present invention relates generally to the field of alcohol consumption monitoring. More specifically, the present invention relates to a consumption tracking beverage container which allows a user to track the amount of wine or alcohol that they consume over time from said container. Further, the container may be wirelessly paired to a mobile application on a smart device to allow the user to analyze his or her alcohol consumption trends and patterns over time.

An object tracking system includes a sensor and a tracking system. The sensor is configured to capture a first frame of a global plane for at least a portion of a space. The tracking system is configured to receive a first coordinate in the global plane where a first marker is located in the space and to receive a second coordinate in the global plane where a second marker is located in the space. The tracking system is further configured to identify the first marker and the second marker within the first frame, to determine a first pixel location in the first frame for the first marker, to determine a second pixel location in the first frame for the second marker, and to generate a homography based on the first coordinate, the second coordinate, the first pixel location, and the second pixel location.

An object tracking system that includes a sensor and a tracking system. The sensor configured to capture a frame of at least a portion of a rack within a global plane for a space. The tracking system is configured to detect an item was removed from the rack. The tracking system is further configured to receive the frame of the rack, to identify a marker on an item within a predefined zone in the frame, and to identify the item associated with the identified marker. The tracking system is further configured to determine a pixel location for a person, to determine the person is within the predefined zone associated with the, and to add the identified item to a digital cart associated with the person.
