BRIEF DESCRIPTION OF THE DRAWINGS 0 A preferred embodiment of the present invention will now be described with reference to the following drawings in which: Figs la to d show a power plug according to a first aspect of the present invention; iV" Fig 2 shows a temperature probe according to a second aspect of the present invention; Fig 3 shows a power cord according to the first aspect of the present invention; Fig 4 shows the power cord of Fig 3 in use; and Fig 5 illustrates an alternative embodiment of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Figs la to d show a perspective view, rear view, side view and front view respectively of a plug 10 according to a preferred embodiment of the present invention. Plug 10 includes pins 11, 12 and 13 for insertion into a power socket (not shown) as is standard in many countries including Australia. Of course, it will be understood that the configuration of pins may vary depending upon the configuration of the power sockets in a given country. Pins 11 to 13 are supported in pin support 14 connected to plug head 15. Power cord connector 16 is disposed on plug head 15 to receive a power cord (not shown) to transfer electrical power from the power source to an electrical device connected to the other end of the power cord.
As can be seen clearly in Fig ld, there is disposed on plug 10 peripheral electronics in the form of a display unit 17 and one or more control units 18. Display unit 17 will display one or more parameters such as temperature relating to an electrical device connected at the other end of the power cord connected to power cord connector 16.
Similarly, control unit 18 can transmit signals to the electrical device connected at the other end of the power cord to control one or more parameters of the electrical device.
Signals may be transmitted and received between the peripheral electronics on plug head 15 and the electrical device via one or more conductive paths which in a preferred embodiment, would be embedded within the electrical power cord, as would be understood by the person skilled in the art. However, the signals could conceivably be transmitted and received via radio frequency means or other wireless means as would be understood by the person skilled in the art.
A preferred application of the plug of Figs la to d is shown in Fig 2, where there is shown plug 10 connected to an electrical device 30 via power cord 20. In this application, electrical device 30 is a temperature probe which is used to determine the temperature of an additional electrical device (not shown) such as a frying pan or other heat generating device. To sense a temperature, probe 30 must be brought within close proximity to the heat generating device and may be exposed to significant temperatures. Such exposure could damage any peripheral electronics located on the probe and thus according to the invention, peripheral electronics constituting a display unit and/or control units, are distanced from the probe and disposed on the plug.
In Fig 3, a different embodiment of the invention is shown where temperature probe is replaced by an electrical connector 40 for connection to another electrical device such as a frying pan. Connector 40 is a standard electrical connector which plugs into electrical devices such as frying pans as is commonly done. However, connector may be modified to allow the transfer of control and display signals between plug and the electrical device.
In Fig 4, the application of the device of Fig 3 is shown in relation to an electric frying pan 50. In this case, as well as generating significant heat in the region about frying pan 50, splashing of oil and other hot substances commonly occurs, which may also damage any peripheral electronics. With the peripheral electronics located on plug and away from pan 50, the risk of damage of the peripheral electronics is greatly reduced.
Of course it is within the scope of the present invention to have the peripheral electronics as a separate stand alone unit which is able to be kept remote from the electrical device and need not necessarily be disposed on the plug. The peripheral electronics could be disposed on a separate unit which may be separately connected to the electrical device via an additional cord or via wireless means and simply disposed and used away from the electrical device. However, it is preferred that the peripheral electronics are disposed on the plug as this provides a convenient means of supporting the peripheral electronics while at the same time minimising the number of components required. Furthermore, the power cord 20 which is traditionally used to connect plug 10 to the electrical device may be used as a convenient means of transmitting signals between the two elements.
In Fig 5, a further alternative embodiment is shown where the peripheral electronics 17, 18 are encased in a separate unit 19 which is disposed along the length of cord Cord 20 can be manufactured with unit 19 or unit 19 may be retro-fitted to cord 20 by either inserting a signal path within cord 20 or providing a separate signal path outside or cord 20 or of course, simply relying on wireless technology.
The above has been described in the context of a preferred embodiment and variations thereto, however it will be understood by the person skilled in the art that many other variations and modifications are possible within the scope of the present invention. For example, the peripheral electronics need not be limited to display or control elements, but could encompass any suitable electronics that is required to be protected from damage. For example, the peripheral electronics could include a scanner/barcode reader to allow recipes or programs to be scanned in. The program may contain time and temperature settings as well as feedback prompts. The programs could be obtained from a participating website or in recipes found in cook books having a barcode system similar to the G-code for programming video recorders.
