Abstract: An apparatus is provided for displaying and demonstrating an electronic imaging device such as a camcorder. The apparatus includes a holder for receiving and holding the imaging device and a display monitor for demonstrating the performance of the imaging device. Additionally, the apparatus includes a detector for detecting displacement of an imaging device from a holder and a controller for operatively connecting the imaging device to the display monitor upon detecting displacement of the imaging device. The method for displaying and demonstrating an imaging device includes the steps of providing a holder for each imaging device on display, detecting displacement of any imaging device from any holder and connecting any imaging device displaced from any holder to a monitor in order to demonstrate the imaging device.

Abstract: A circuit system for selectively switching between main and remote loudspeakers includes a pair of input terminals for applying an input audio signal to the loudspeakers. A first selector switch contact is provided in series with the main loudspeakers. A second selector switch contact is provided in series with the remote loudspeakers. A current-dependent resistance element is provided in series with the remote loudspeakers to protect the remote loudspeakers from overdrive. The circuit system may also include a second current-dependent resistance element and a cooperating defeat switch contact as well as a resistor and associated load limiting switch contact all in series with the remote loudspeakers.

Abstract: A switching network for interconnecting selected products of different electronic groups on display for purposes of active demonstration includes a plurality of nodes. Each product on display is operatively connected to one node. Each node further includes a microcontroller. A bus operatively connects the microcontrollers together as well as the products on display. The bus allows two-way communication between the microcontrollers that supervise all network functions. Additionally, each of the nodes includes a product selector switch and cooperating relay for selectively activating an adjacent product connected to the node and an indicator lamp that when illuminated indicates that the corresponding electronic product is connected for active demonstration.

Abstract: A switching network including a plurality of nodes, one node connected to a product of different electronic product groups on display. Each node includes a satellite node microprocessor and a cooperating product selector switch for selectively actuating said cooperating connected electronic product. An indicator lamp is also provided at each node. Illumination of the lamp indicates an operating condition of the electronic product connected to the node. Further, each node includes an address memory to identify the node and the connected electronic product. The satellite node microprocessors of each node are operatively connected by a bus to a central control unit. The central control unit includes a host microprocessor for supervising all network functions and product selectors for actuating selected electronic products connected to the nodes.

Abstract: A solderless connector includes a body member having a resilient collet for engaging an insulated electrical conductor. A securing sleeve includes mating threads for engagement with the body member. As the sleeve is tightened on the body member anchoring cams on the sleeve press the resilient collet into the insulation about the electrical conductor so as to securely hold the body member in position. A conductor spike, concentrically disposed within the collet and attached to the body member makes contact with the electrical conductor. The solderless conductor also includes a pin connector terminal for making electrical contact with an electrical apparatus. The pin connector terminal includes a frangible weakened zone so that the terminal may be broken off from the body member if desired. A threaded connection may then be utilized to mount an alternative terminal, such as a banana plug or spade terminal, to the body member.
