A product display shelf, system and method are disclosed. The product display system includes a shelf unit having a back shelf portion and a front shelf portion. The back shelf portion includes a first connecting element for releasably attaching the back shelf portion to an electrically powered support member, and the front shelf portion includes a second connecting element for releasably attaching the front shelf portion to the back shelf portion. The front shelf portion can also include a body portion and a display panel connected to or integral with the body portion, suitable for displaying information to a user.

A lighted gaming furniture system including a piece of furniture, at least one light, a power source, a sensor, a controller and a gaming system. The gaming system operably linked to the controller. The at least one light is attached to the piece of furniture. The sensor is capable of receiving sound emitted by the gaming system. The controller is operably attaching the power source, the sensor and the at least one light to control illumination of the at least one light.

One of more panels of the cabinet include at least one conductive region that is optionally covered by an insulative covering. These conductive regions are coupled to an external power source. Shelves, drawers, other cabinet components, electrical devices in a cabinet (including, but not limited to, a motor, lights, outlet, appliance, sensor, processor, etc.), and the like can further conduct or receive electrical energy by electrically coupling to the conductive regions within the panels of the cabinet, for example, through shelf pins that are inserted into holes in the panels.

A colored lighting system with a scheme to indicate the nature of a student's participation action. Students are outfitted with desktop-mounted lights, preferably capable of emitting numerous colors in a serial fashion. The teacher can then read the indicated color pattern, or light from an individual student, and select whether to interrupt and in what order to address each student. The method may be used for lecture, testing, in-class projects, and beyond.

The invention relates to a power-supply device for an item of furniture that has a furniture carcass and at least one movable furniture part for supplying at least one electrical load with electrical power, the device comprising: at least one current-supply bar, wherein the current-supply bar can be arranged on the furniture carcass or on the movable furniture part; at least one contacting device, wherein the contacting device can be arranged at least in part on the movable furniture part or on the furniture carcass; wherein the contacting device comprises at least one contact element for galvanically conductively contacting the at least one current-supply bar, and at least one switchable load-switch element for allowing a current supply from the current-supply bar to the at least one electrical load via the contacting device.

An illuminated table for providing illumination proximate to the table includes a housing that defines an interior space. The housing is substantially transparent. An orifice is centrally positioned through an upper end of the housing. The orifice defines an inner lip that extends annularly around a circumference of the upper end. A plurality of bulbs is selectively couplable to the housing and is positionable in the interior space. A plurality of first plates is selectively couplable to the housing to close the orifice. A respective first plate is positionable on the housing to serve as a tabletop. The plurality of bulbs is configured to illuminate an area proximate to the housing.

Product display systems are provided. The product display system may include a product display assembly. The product display system may also include a retail product positioned in proximity to the product display assembly. The product display system may further include a power source configured to output electrical current. At least one of the product display assembly and the retail product may include a shape-memory alloy. The shape-memory alloy may be configured to change from a first shape to a second shape in response to heat produced from electrical current provided by the power source.

One of more panels of the cabinet include at least one conductive region that is optionally covered by an insulative covering. These conductive regions are coupled to an external power source. Shelves, drawers, other cabinet components, electrical devices in a cabinet (including, but not limited to, a motor, lights, outlet, appliance, sensor, processor, etc.), and the like can further conduct or receive electrical energy by electrically coupling to the conductive regions within the panels of the cabinet, for example, through shelf pins that are inserted into holes in the panels.

A room caddie having a self-supporting box with a first interior chamber extending into the box from the top and a second interior chamber separate from the first interior chamber. The second interior space comprising a plurality of interior electrical power sources. A fixed cover is disposed over the first interior chamber and includes a cylindrical cup holder, at least one exterior electrical power source and a first part of a two-part releasable connector disposed in the fixed cover. A moveable lid is disposed over the second interior chamber at the top of box to provide access into the second interior chamber.
