Abstract: A novel form of food heating lamp is disclosed with built-in sensors for auto-detection of food. This exemplary innovation provides sensors capable of measuring distance and can be added or replaced to be readily used in food warming equipment already in the field to allow for this energy saving capability to be widely enabled at low cost. The associated application allows easy control, reminders, notifications and reporting on user request.

Abstract: A system and method for identifying the origin of photographic images and selecting photographic images according to the identified origin for inclusion in a set of photographic images employs a high contrast identifiable label disposable at one or more points in one or more sizes within the camera field of view for images of the label to be included in any photographic image. The label can be one of a plurality of different styles of each label. Each different label bears a unique identification code in the form of a decoder bull binary number. Each label also comprises an asymmetrical element. Photographic images are scanned to identify any labels. If labels are found, label images are adapted for size, flatness of face presentation and rotational orientation. The unique identification code is read as a sequence of binary digits provided by presence or absence of code elements.
