Abstract: The present disclosure relates to an interactive light switch accessory apparatus. The apparatus comprises an electronic plate device mounted to a surface. The plate device comprising at least one opening to accommodate to at least one switch mounted to the surface. The apparatus further comprises one or more light emitting elements disposed in the plate device, and a computing module in communication the light emitting elements and the plate device. The apparatus further comprises one or more sensors in communication with the plate device configured to collect information related to the environment proximal to the plate device. The plate device is configured to communicate information to a user.

Abstract: A light switch apparatus includes a network communication unit and an output unit. The network communication unit is configured to receive electricity price rate server information from a server, and generate a first high range electricity price output data and a second low range electricity price rate data according to the electricity price rate server information. The output unit is configured to display at least a first output color in response to receiving the first high range electricity price output data from the network communication unit, and a second output color in response to receiving the second low range electricity price rate data from the network communication unit.

Abstract: A utensil retracting device is described that can assist with serving food and storing a utensil used for serving the food. For example, the utensil retracting device can be secured to a part of a food service area and can also be secured to a utensil that can be used for serving food. The utensil retracting device can secure the utensil in a desired storing position and/or area. In addition, the utensil can be used within a range defined by a length of a tether that secures the utensil to the utensil retracting device. The utensil retracting device can also retract the tether in order to return and secure the utensil back to the desired storing position and/or area. The utensil retracting device can assist in preventing food contamination, such as from direct contact with diners as a result of misplaced utensils.
