Description:
TECHNICAL FIELD 
     The present invention relates generally to retail selling of consumer electronics and, more particularly, to an apparatus and method for displaying and actively demonstrating the operating features and performance qualities and characteristics of a camcorder. 
     BACKGROUND OF THE INVENTION 
     Retailers largely rely upon active demonstrations to present electronic consumer products and, particularly, audio and video entertainment products to customers. Such active demonstrations allow the customers to explore product features, directly compare products and match customer needs and desires with the available products. Accordingly, active demonstrations are very effective in facilitating sales of consumer electronic products. 
     It is also clear that any system for actively demonstrating consumer electronic products must also protect those products from theft. Further, such a system should be as vandalism proof as possible. These additional considerations cannot be simply ignored in today&#39;s cultural environment. 
     The present invention relates to the display and demonstration of camcorders. The camcorder has evolved into the product of choice for consumers wishing to record live picture with sound. The range of technical features now available in camcorders demands that the shopper be free to handle them in order to evaluate picture qualities such as detail and color rendition, screen stabilization performance, ease-of-use features such as focus and zoom and aesthetic values including weight. Further, since the trend in retailing is away from skilled sales staff and towards self-service, it is left up to the consumer to demonstrate electronic goods themselves. Accordingly, simplified display function is an essential element of any good demonstration and display system. 
     In order to provide the capability to demonstrate such a wide range of camcorder features, the present invention provides a convenient support for displaying the camcorder in the manner similar to that disclosed in U.S. Pat. No. 5,146,205 to Keifer et al. More specifically, an upright cylindrical column is mounted to a base plate that is anchored or otherwise secured to a display fixture. A pin is secured to the base of the camcorder. The pin is removably held in the column so that the camcorder is conveniently displayed and also may be lifted from the column for inspection and demonstration of features. 
     While the display column disclosed in the Keifer et al. patent is quite effective, it does suffer from several shortcomings. First and foremost, the Keifer et al. display system fails to provide for automatic demonstration of the camcorder as it is lifted from the stand by the consumer. This is a particularly important feature in today&#39;s self-service retail environment. Second, the Keifer et al. display system utilizes a cumbersome product security system including separate mechanical and electronic security cables. This is a relatively cumbersome system that requires some extra time to install and can make consumer handling of the camcorder awkward and inconvenient. This latter problem is of particular concern since it discourages the customer from fully investigating the product thereby interfering with a potential sale. 
     SUMMARY OF THE INVENTION 
     Accordingly, it is a primary object of the present invention to provide an apparatus and method for demonstrating a camcorder overcoming the above described limitations and disadvantages of the prior art. 
     Another object of the present invention is to provide an apparatus and method for conveniently displaying and automatically demonstrating camcorder performance when the camcorder is lifted by a customer from the display stand for inspection. Specifically, the video output of the camcorder is automatically connected to a nearby monitor in order to display the picture being picked up by the camcorder. In this way, the retailer may share costly and spaced-consuming television monitors among two or more camcorders while freeing the shopper from the burden of (1) learning that the camcorder of interest must be manually selected to get the picture up on the monitor and (2) finding and operating the switch that enables the selection. Additionally, since the manual selector switch is often the target of vandalism, the elimination of a manual selector switch is a very significant advantage provided by the present invention. 
     Still another object of the present invention is to provide a camcorder display and demonstration system that provides a looped current through the conventional stereo patch cord utilized to connect the camcorder&#39;s audio and video jacks to a playback monitor. When the continuity of the camcorder loop is broken by the cutting or disconnection of the patch cord, the resulting voltage increase between the audio and video jacks results in the triggering of a theft alarm. Advantageously, this eliminates the need for separate security cables which may be found cumbersome and inconvenient when a consumer handles and inspects a camcorder. 
     Additional objects, advantages and other novel features of the invention will be set forth in part in the description that follows and in part will become apparent to those skilled in the art upon examination of the following or may be learned with the practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instrumentalities and combinations particularly pointed out in the appended claims. 
     To achieve the foregoing and other objects, and in accordance with the purposes of the present invention as described herein, a new and improved apparatus and method for displaying and demonstrating a camcorder is provided. The apparatus comprises a holder for receiving and holding a camcorder and its display monitor for demonstrating camcorder performance. Further, the apparatus includes a detector for detecting displacement of the camcorder from the holder as well as a controller for operatively connecting the camcorder to the display monitor upon detecting displacement of the camcorder. Thus, it should be appreciate that when the camcorder is handled by a customer and removed from the display stand for inspection, a nearby monitor automatically begins demonstrating performance of the camcorder without delay or any further action on the part of the customer. This is the most convenient and effective demonstration network that may be developed for the display and demonstration of camcorder performance. 
     Still further, the apparatus includes an effective security feature. Specifically, a patch cord is provided for delivering audio and video signals from the camcorder to the controller which serves to route those signals to the television monitor at the time the camcorder is being inspected by a consumer. The controller also includes a means for generating a loop current in the patch cord at all times and a security alarm. Any interruption in the loop current caused by disconnection or cutting of the patch cord causes the alarm to be activated. Accordingly, an efficient security system for deterring theft is provided without the need for separate mechanical or electronic security cables as utilized in typical prior art designs. 
     In accordance with yet another aspect of the present invention, a novel and effective method for displaying and demonstrating a camcorder is provided. The method includes the steps of providing a holder for each camcorder on display, detecting displacement of any camcorder from its holder and connecting any camcorder displaced from any holder to a monitor in order to demonstrate the camcorder. This simple and straightforward method provides a more efficient and consumer friendly approach for demonstrating the performance features of a camcorder. This represents a significant advantage in today&#39;s self-service retail environment that promotes sales to the advantage of the retailer. 
     Still other objects of the present invention will become apparent to those skilled in this art from the following description wherein there is shown and described a preferred embodiment of this invention, simply by way of illustration of one of the modes best suited to carry out the invention. As it will be realized, the invention is capable of other different embodiments and its several details are capable of modification in various, obvious aspects all without departing from the invention. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive.

     DETAILED DESCRIPTION OF THE INVENTION 
     Reference is now made to the drawing figures showing the apparatus  10  of the present invention for more efficiently and effectively displaying and demonstrating camcorders in a self-serve retail environment. The apparatus  10  of the present invention may be a stand alone system or may be a part of a switching network for selective product demonstration as set forth and described in U.S. Pat. No. 5,646,602 to Gertz et al., the full disclosure of which is incorporated herein by reference. 
     As shown in FIG. 1, each camcorder C is prominently displayed on a holder  12  comprising an upright cylindrical stand  14  supported on a base  16  that may be secured by a screw or other fasteners to a display fixture F. 
     As best shown in FIG. 1 a , a pin  18  is secured to the camcorder C such as by threading into the tripod stand mounting aperture A of the camcorder. The pin  18  includes a projecting lug  20  sized for smooth sliding receipt into the top of the upright cylindrical stand  14 . In this way, the camcorder C may be readily removed from the holder  12  when a customer desires to handle the camcorder to inspect and review its functions. When finished, the customer may simply replace the camcorder C back on the holder  12  by inserting the lug  20  of pin  18  into the upright cylindrical stand  14 . 
     A momentary switch  22  in the stand  14  functions as a detector for detecting when the camcorder C is displaced or removed from the holder  12 . An indicator lamp  24  may be mounted to the cylindrical stand  14  and operatively connected to the switch  22 . The lamp  24  lights whenever the picture from the camcorder C is being displayed upon a monitor  26  in a manner described in greater detail below. 
     As best shown in FIG. 2, substantially any number of camcorders up to  100  represented as C 1 -C n  may each be positioned on its own individual holder  12  for purposes of customer display and demonstration. Each such holder  12  is equipped as described above with the momentary switch  22  and the indicator lamp  24  as shown in FIG. 1 a . A pair of control wires  28  connects each momentary switch  22  to a connecting means/controller  30 . Similarly, an audio/video patch cord  29  connects each camcorder C 1 -C n  to the controller  30 . 
     As shown in FIG. 3, each controller  30  includes a microcontroller  32 . The microcontroller  32  may, for example, be a type PIC16C55 unit including appropriate software support defining the logic of the controller as a whole stored in an internal program memory ROM  34  (see FIG.  4 ). Such a microcontroller  32  with internal read only memory integrated circuit is provided by Audio Authority Corporation Part No. 135-001 available from Audio Authority Corporation, Lexington, Ky. As best shown in FIG. 4, the microcontroller  32  includes a central processing unit or CPU  36  having a CPU control  38  to supervise operation and an arithmetic logic unit or ALU  40  for mathematical and logic functions. A system clock  42  operatively connected to the central processor unit  36  synchronizes all operations. 
     The microcontroller  32  also includes input and output registers  44  to send and receive data, the read only memory or ROM  34  for program storage and random access memory or RAM  46  for temporary data storage. The system clock  42 , ROM  34  and RAM  46  may be physically inside or outside the microcontroller integrated circuit. An internal bus  48  allows communication between the various components of the microcontroller  32 . 
     As best shown with reference to FIGS. 2 and 3, each controller  30  includes a switching device  50  such as a relay or other switching device known in the art. The switching device  50  is actuated by the microcontroller  32  through the switching device driver  52 . The switching device  50  operatively connects the audio and video outputs of a selected camcorder C with the monitor  26  through the patch cord  29  and the signal bus  56 . 
     The controller  30  also includes an indicator driver  58 . The microcontroller  32  operates through the indicator driver  58  to control the indicator lamps  24  on the holders  12  for each camcorder. Specifically, when the camcorder C is selected for demonstration by the customer lifting it from its stand  14 , the closure of switch  22  sends a signal along control wires  28  to the controller  30 . In response to this signal, the microcontroller  32  acts through the indicator driver  58  to output lamp current, which flows through switch  22  while the camcorder is off the stand and switch  22  is closed, but flows through lamp or light emitting diode  24  when the camcorder is on the stand and switch  22  is open. Therefore, lamp  24  illuminates to indicate which camcorder is presently being displayed on the television monitor when all the camcorders are on their stands. 
     A third wire can be added to the pair of control wires  28  between camcorder stand  14  and controller  30  to operate lamp  24  independently of switch  22  in order to indicate the active camcorder regardless of whether it is on or off the stand. 
     Still further, the controller  30  includes an alarm driver  62  which is operatively connected to an alarm  64 , such as a siren or other alarm device, and a reset switch  66 . Specifically, microcontroller  32  feeds a small loop current (between approximately 1-10 milli amps) through the internal control line  68  through the patch cord  29  which loops through the camcorder C and back to ground  70 . In this way the microcontroller  32  is able to monitor the continuity of the audio and video cable shield conductors of the patch cord  29 . In the event the patch cord  29  is disconnected from the camcorder C or the controller  30  or the patch cord is severed, the continuity is broken and the resulting voltage increase between the audio and video jacks constituting a camcorder port is detected. This causes the microcontroller  32  to activate the alarm  64  by operation of the alarm driver  62  through the control line  72 . A convenient reset switch  66  connected to the microcontroller  32  through the control line  80  may be accessed by store personnel to defeat the alarm when desired. 
     The controller  30  may be powered by a DC power source  74  or any other appropriate means known in the art. Further, the controller  30  may include a communication bus running from the microcontroller  32  to another like controller  30  if (1) a multiple controller system or (2) a demonstration network system such as described in issued U.S. Pat. No. 5,646,602 to Gertz et al. is being utilized. 
     The method of the present invention will now be described in detail. Specifically, as should be apparent from the earlier description and particularly from viewing FIG. 2, a holder  12  is provided for each camcorder C 1 -C n  on display. Each holder  12  includes a momentary switch  22  and an indicator lamp  24  as shown in FIG. 1 a . Each of the switches  22  and indicator lamp  24  are connected to the controller  30  through a pair of control wires  28 . When a customer removes or lifts any one of the camcorders C 1 -C n  from a holder  12 , the switch  22  corresponding to that camcorder sends a signal along the control wires  28  to the controller  30 . Receipt of this signal causes the microcontroller  32  to simultaneously (1) light the indicator lamp  24  at the stand  12  from which the camcorder C has been lifted through operation of the indicator driver  58  and (2) route the video or audio and video signals from the patch cord  29  of the selected camcorder through the switching device  50  and the feed line  56  to the monitor  26  by operation of the switching device driver  52 . When the customer replaces the selected camcorder C 1 -C n  on the holder  12 , the picture from that camcorder continues to be displayed through the monitor  26  and the associated indicator lamp  24  illuminates. 
     However, when the customer lifts and displaces another camcorder C 1 -C n  from a holder  12 , the controller  30  receives the detection signal from the associated momentary switch  22 . The microcontroller  32  then responds through the indicator driver  58  and extinguishes the previously illuminated indicator lamp  24 . Simultaneously, the microcontroller  32  operates through the switching device driver  52  and the switching device  50  to disconnect the previously selected camcorder from the monitor  26  and connect the video or audio and video signals from the newly selected camcorder C 1 -C n  to the monitor. Of course, at all times, the loop current is provided through the patch cord  29  leading to each camcorder C 1 -C n  as a continuous theft deterrent. As stated above, any disconnection of the patch cord  29  from one of the camcorders C 1 -C n  results in the sounding of the alarm  64 . 
     In summary, numerous benefits result from employing the concepts of the present invention. Advantageously, if a customer is curious enough to lift any prominently displayed camcorder C 1 -C n  from its holder  12 , demonstration of the camcorder&#39;s video or audio and video signal is immediately initiated at the monitor  26  located adjacent the camcorder. Since this is done automatically without any manual switching or further effort on the part of the customer, the provided self-service demonstration is far more convenient and effective as a marketing tool. This same marketing advantage is provided each time the customer lifts another camcorder for inspection and/or demonstration thereby readily encouraging comparison and promoting a sale. No other device in the marketplace provides this “automatic” demonstration performance. 
     The foregoing description of a preferred embodiment of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings. 
     For example, more than one monitor  26  may be connected to a controller. Each connected monitor  26  may be associated with a small group of camcorders (e.g. 2-4) that are displayed around that monitor. When each camcorder of that subgroup is lifted, the video or audio and video signal produced by that camcorder is routed by the controller  30  to the associated monitor  26 . That signal pathway is maintained until the customer selects another camcorder of that subgroup. Further, the controller  30  may be provided with logic that automatically subquentially scans through the camcorders associated with a particular monitor when none has been disturbed for a predetermined period of time. Since the controller  30  detects missing camcorders, the logic can skip over unpopulated stands  12  such as when the camcorder associated with a stand has been sold off the display. 
     The embodiment was chosen and described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
