  • Patent number: 8587446
    Abstract: The present disclosure is directed to systems and methods for monitoring and displaying occupancy of a seating area, such as a theater. In a seating area there are chairs for use by patrons. There is a system and method for determining and communicating occupancy information to a display corresponding to the chairs in the seating area. On each chair there is affixed a wireless sensing device that detects when a patron has sat in the chair. When a patron sits in the chair, the wireless sensing device sends an occupied signal to an occupancy monitoring computer system. The occupancy monitoring system changes the status of the corresponding chair to occupied and updates the output on the display available for viewing by all patrons. When the occupied state of the chair changes, the wireless sensing device updates the occupancy status at the occupancy monitoring system.

  • Publication number: 20130234858
    Abstract: A weight sensing device includes a casing, a weight sensing module and a light emitting module. A container placing area and a light emitting area are defined on a surface of the casing and staggered with each other. The weight sensing module is disposed in the casing and corresponding to the container placing area. The weight sensing module records a weight threshold. The light emitting module is disposed in the casing and corresponding to the light emitting area. When a container, which contains a substance, is placed on the container placing area, the weight sensing module senses a current weight of the container and the substance and compares the current weight with the weight threshold. When the current weight is smaller than the weight threshold, the weight sensing module drives the light emitting module to emit light, which is projected through the light emitting area.
