Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to a forced cell phone call disruption device for use in connection with cell phone accessories. The forced cell phone call disruption device has particular utility in connection with forced cell phone disruption device using the vehicle transmission as the switch.  
           [0003]    2. Description of the Prior Art  
           [0004]    Forced cell phone call disruption devices are desirable for reducing the number of cell phone calls which are taken while a user is driving a vehicle. Current statistics show that the automobile accident rate while using a cell phone is much higher than the average rate. A forced restriction of cell phone use during driving may be the only viable solution. A need was felt for a forced cell phone call disruption device that uses the state of the transmission as the gating switch for cell phone use.  
           [0005]    The use of cell phone accessories is known in the prior art. For example, U.S. Pat. No. 5,819,171 to Hoogerwerf discloses an automated forced call disruption for use with wireless telephone systems that provide the ability to disrupt normal completion of a specific call made through a wireless telephone system. The specified call can be forced to be immediately ended, re-routed immediately to a selectable destination, or linked to a local voice frequency interface. The disruption of the call can occur at any point in time over the duration of the call. The decision to disrupt the call, as well as which action to take against the call, can be selected manually by a human or automatically through a standard data interface provided. The call disruption apparatus can be interfaced to the wireless system through a circuit physically connected to the wireless telephone system equipment, or through a modulated radio frequency interface. However, the Hoogerwerf, et al. &#39;171 patent does not use the transmission as a switch to turn the call disruption on and off.  
           [0006]    Similarly, U.S. Pat. No. 6,222,458 to Harris discloses an automatic cell phone detection at a combustible delivery station that provides protection against use of a two way radio, e.g. a cellular phone, at a combustible delivery station. One mode is active, and detects operating cell phones at the gas station. The phones can be detected using Bluetooth. The pump can be turned off when the alarm is detected. Another mode is passive. This mode can be via shielding, alone or with RF jamming. However, the Harris &#39;458 patent does not use the transmission as a switch to turn the call disruption on and off.  
           [0007]    Lastly, U.S. Pat. No. 5,442,805 to Sagers, et al. discloses a location-based adaptive radio control that provides for a radio having adjustable operating parameters to adjust at least one such adjustable operating parameter based on the current location of the radio. Operating parameters which may be so adjusted include, but are not limited to, the following: transmitting power, operating channel, operating band, modulation type, modulation index, frequency deviation, squelch setting, channel spacing, control channel (for trunked communications), noise blanker characteristic, and receive bandwidth. In another embodiment, transmissions by the radio can be inhibited as a function of the location when it is determined that the location is within a hazard area. However, the Sagers , et al. &#39;805 patent does not use the transmission as a switch to turn the call disruption on and off.  
           [0008]    While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a forced cell phone call disruption device that allows forced cell phone disruption device using the vehicle transmission as the switch. The Hoogerwerf, et al. &#39;171, Harris &#39;458 and Sagers, et al. &#39;805 patents make no provision for using the transmission as a switch to turn the call disruption on and off.  
           [0009]    Therefore, a need exists for a new and improved forced cell phone call disruption device which can be used for forced cell phone disruption device using the vehicle transmission as the switch. In this regard, the present invention substantially fulfills this need. In this respect, the forced cell phone call disruption device according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of forced cell phone disruption device using the vehicle transmission as the switch.
