Description

BACKGROUND

Mobile devices such as wireless devices, including, for example, cellular telephones, smart phones, laptop computers, notebook computers, tablet devices (e.g., iPad by Apple®) are ubiquitous in modern society. Use of such mobile devices while operating a vehicle, however, can be hazardous. The problem is exacerbated for inexperienced operators of the vehicle, such as youngsters just learning how to drive. Rates of vehicular accidents where mobile devices are involved are rising, especially with teenagers. Text messaging while operating a moving vehicle can be dangerous and has been linked with causing accidents. More generally, operating any keyboard while operating a vehicle can be dangerous.

Thus, the widespread adoption of mobile devices and common use of the devices while driving has raised concerns about the distraction of drivers. A driver speaking or text messaging on a mobile telephone may become mentally distracted from driving and lose control of the vehicle that he or she is driving. Thus, it is not uncommon to see an individual involved in an accident who was speaking or text messaging on a mobile device rather than paying attention to the road. Studies now suggest that individuals speaking on mobile telephones while driving a car may be as impaired as a person who drives while intoxicated. Not only is the driver mentally distracted, but eyes of the driver are diverted for dialing, looking to see who an incoming call is from.

It would be highly desirable to detect the presence of a mobile device such as a wireless device within a vehicle and control or disable the operation of the mobile device.

SUMMARY

In one embodiment, a method for determining the presence of a mobile device located in a predetermined detection zone within a vehicle is provided. A detection module receives a communication signal. The detection module determines that the communication signal was transmitted by a mobile device located within a predetermined detection zone within a vehicle. A control module transmits a control signal to the mobile device located within the predetermined detection zone.

DESCRIPTION

The present disclosure describes embodiments of an apparatus, system, and method for detecting the presence of a mobile device such as a wireless device and controlling or disabling the operation of the mobile device when it is detected. In particular, the present disclosure is directed to embodiments of an apparatus, system, and method for detecting the presence of a mobile device such as a wireless device in a predetermined location within a vehicle and disabling some or all of the functions of the mobile device when it is detected in the predetermined location. More particularly, the present disclosure is directed to automatically preventing a person in the driver's seat of a vehicle from text messaging and doing other similar excessively dangerous activities with the mobile device.

It is to be understood that this disclosure is not limited to particular aspects or embodiments described, as such may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects or embodiments only, and is not intended to be limiting, since the scope of the apparatus, system, and method for detecting the presence of a mobile device within a vehicle and controlling the operation of the mobile device when it is detected is defined only by the appended claims.

In one embodiment, the present disclosure provides an apparatus, system and method for detecting and restricting the use of mobile devices within a vehicle, whether the vehicle is moving or stationary. Mobile devices, such as wireless devices, may include without limitation, for example, cellular telephones, smart phones, laptop computers, notebook computers, tablet devices (e.g., iPad by Apple®), Netbook®, among other wireless mobile devices that a user can interact with while located in a vehicle. In one embodiment, the presence of a mobile device in the driver's side area of the vehicle is detected by at least one sensor located within the vehicle. When the presence of the mobile device is detected, the operation of the mobile device is controlled, disabled, or modified with respect to the person located in the driver side area of the vehicle but not with respect to other persons located in other areas of the vehicle.

FIG. 1 illustrates a vehicle 100 that includes a cabin 104 for accommodating an individual in a driver seat 106. It will be appreciated in accordance with the present disclosure that the term vehicle is used broadly and is meant to include any kind of transportation vehicle. For example, the vehicle 100 may be any type of automobile, truck, sport utility vehicle, aircraft, watercraft, spacecraft, or any other means of transportation, or combinations thereof, where communications by the driver using a mobile device is to be detected and controlled.

Disposed on or within the dashboard 108 of the vehicle 100 is a mobile device detection and control system 102. In one embodiment, the mobile device detection and control system 102 is configured to detect the presence of a mobile device located in the driver seat 106 side of the vehicle 100 and control the operation of the mobile device by either jamming the mobile device, jamming certain functions or aspects of the mobile device, or redirecting the operation of the mobile device to a hands-free alternate system. In other embodiments, at least some elements or components of the mobile device detection and control system 102 may be located in other areas of the vehicle 100.

It may be desirable to place detection and jamming elements of the mobile device detection and control system 102 as close to the driver as possible. For example, sensors and directional antennas of the mobile device detection and control system 102 may be located in proximity of the driver seat 106. This configuration provides the more precise detection of the presence of the mobile device in the driver seat 106 side of the vehicle 100 and prevents interference with other mobile devices or other persons located within the vehicle 100 to allow persons in the passenger seats to use the mobile device while the driver is unable to. Other elements or components such as control logic may be located in other locations of the vehicle 100 away from the driver seat 106.

In one embodiment, the mobile device detection and control system 102 is configured to detect signal transmissions from mobile devices located in or proximity of a detection zone. In accordance with the described embodiments, the detection zone is defined as a zone substantially in or in proximity of the driver seat 106 side of the vehicle 100. In other embodiments, however, the detection zone may be any predefined zone within the vehicle 100, without limitation. In one aspect, the detection portion of the mobile device detection and control system 102 may tuned to detect signal transmissions in frequency bands used by conventional mobile telephones operating in common cellular channels. Once the signals are detected, the mobile device detection and control system 102 wirelessly controls the operation of the mobile device in one or more ways. For example, in one embodiment, the mobile device detection and control system 102 transmits control signal to disable the operation of the mobile device by way of jamming signals that interfere with the communication mechanism of the mobile device. While the jamming signals are transmitted, the mobile device or other communication device within the detection zone is rendered either inoperable or operable only in a state of limited capacity. The jamming signals forcibly interfere with the communication mechanism of the mobile device by broadcasting noise or other signals on one or more channels used by the mobile device. In other embodiments, a jamming signal may be interpreted by the mobile device to disable one or more functions of the mobile device. In such an embodiment, the jamming signal may be communicated to the mobile device through a secondary channel, such as a Bluetooth wireless connection or any other connection that is secondary to the primary cellular communication channel. In some embodiments, the jamming module may communicate on the primary communication channel of the mobile device only or in addition to one or more secondary channels.

Accordingly, the mobile device detection and control system 102 can either completely block the ability to receive or send a call on a mobile device, or sufficiently interfere with the mobile device signal so as to make the mobile device usage undesirable. For example, if the jamming signal simply interrupts a sufficient portion of the conversation, the user will simply either postpone the conversation or pull over so the conversation can continue uninterrupted. In another embodiment, the mobile device detection and control system 102 may disable the operation of certain components or functions of the mobile device. For example, the keyboard portion of the mobile device may be jammed to prevent the user from using the text messaging function of the mobile device. In another embodiment, the mobile device detection and control system 102 may direct the operation of the mobile device to a hands-free operation. These and other embodiments are discussed in more detail hereinbelow.

In one embodiment, the mobile device detection and control system 102 initiates the detection process by transmitting probing signals to detect the presence of a mobile device within a detection zone. Once the probing signals are transmitted, the detection and control system 102 waits for an echo signal reflected by the mobile device or a response signal transmitted by the mobile device. If the detection and control system 102 detects the echo signal or a transmission by the mobile device, the detection and control system 102 transmits a control signal to control the operation of the mobile device. For example, in one embodiment, the detection and control system 102 transmits a control signal to disable the operation of the mobile device by way of jamming signals that interfere with the communication mechanism of the mobile device. In another embodiment, the detection and control system 102 may reroute communications to a hands-free system, such as a Bluetooth communication system.

FIG. 2 illustrates one embodiment of a mobile device detection and control system 102. In one embodiment, the mobile device detection and control system 102 is configured to detect the presence of a mobile device 200 located in or in proximity of the driver seat 106 area of the vehicle 100. Once the mobile device 200 is detected, the mobile device detection and control system 102 is configured to control the operation of the mobile device 200. In one embodiment, the mobile device detection and control system 102 comprises a detector module 202 and a control module 204 coupled to the detector module 202. The detector module 202 comprises a multi-band antenna 208 to receive signal transmissions from the mobile device 200 and the control module 204 comprises an antenna 210 to transmit control signal to the mobile device 200. In various embodiments, the detector module 202 and the control module 204 may share an antenna when these components are located in proximity of each other.

In various embodiments, the mobile device 200 may be implemented as a handheld portable device, computer, mobile telephone, sometimes referred to as a smartphone, tablet personal computer (PC), laptop computer, or any combination thereof. Examples of smartphones include, for example, Palm® products such as Palm® Treo® smartphones (now Hewlett Packard or HP), Blackberry® smart phones, Apple® iPhone®, Motorola Droid®, and the like. Tablet devices include the iPad® tablet computer by Apple® and more generally a class of lightweight portable computers known as Netbooks. In some embodiments, the mobile device 200 may be comprise, or be implemented as, any type of wireless device, mobile station, or portable computing device with a self-contained power source (e.g., battery) such as a laptop computer, ultra-laptop computer, personal digital assistant (PDA) with communications capabilities, cellular telephone, combination cellular telephone/PDA, mobile unit, subscriber station, user terminal, portable computer, handheld computer, palmtop computer, wearable computer, media player, pager, messaging device, data communication device, and so forth.

In one embodiment, the detector module 202 is configured to detect presence of the mobile device 200 located within a detection zone 220 defined as a three-dimensional zone within or in proximity of the driver seat 106. Methods of detecting the presence of the mobile device 200 may vary based on the wireless technology communication standards used by the mobile device 200. Examples of wireless technology communication standards that may be used In the United States, for example, may include Code Division Multiple Access (CDMA) systems, Global System for Mobile Communications (GSM) systems, North American Digital Cellular (NADC) systems, Time Division Multiple Access (TDMA) systems, Extended-TDMA (E-TDMA) systems, Narrowband Advanced Mobile Phone Service (NAMPS) systems, 3G systems such as Wide-band CDMA (WCDMA), 4G systems, CDMA-2000, Universal Mobile Telephone System (UMTS) systems, Integrated Digital Enhanced Network (iDEN) (a TDMA/GSM variant) and so forth. These wireless communications standards are fully familiar to those of ordinary skill in the art. The frequency and signal strength of the radio frequency (RF) signals transmitted by the mobile device 200 depend on the network type and communication standard. The detector module 202 detects the RF signal, or simply electromagnetic energy radiation, transmitted by the mobile device 200, generally speaking. Accordingly, in one embodiment, the detector module 202 may be configured to lock onto specific cellular frequencies or cellular frequency bands or may be configured to scan all the available cellular frequencies or cellular frequency bands and lock onto the RF signal emitted by the mobile device 200.

In one embodiment, the detector module 202 may comprise a sensor module 216 coupled to the multi-band antenna 208. The sensor module 216 may be tuned to detect energy at a predetermined signal strength in the electromagnetic signal 206, e.g., RF signal, emitted by the mobile device 200 and received by the antenna 208. It will be appreciated that the signal strength or power of the energy radiated by the electromagnetic signal 206 emitted by the mobile device 200 will be greatest when the mobile device 200 is making an outbound call or otherwise communicating with a cellular base station (e.g., searching for base station signals or in contact with a base station or cell). Very little energy in the electromagnetic signal 206 is radiated when the mobile device 200 is turned off or when it is not communicating with the cellular base station. In the latter case, when the mobile device 200 is turned on but is not communicating with the cellular base station, the mobile device 200 possibly may be detected only if the detector module 202 comprises extremely sensitive components. Most conventional mobile devices 200 radiate energy at a power level ranging from about 0.5 milliwatts (mW) to about several hundred mW. A detector module 202 of suitable sensitivity can be configured to detect electromagnetic signals 206 in this range of power level. Many radio electronic equipment are capable of detecting low-level power in the electromagnetic signal 206 and is one reason why airlines are very sensitive about electronic equipment that operates at key points of the flight, why some electronic equipment should be turned off near blast sites, and why cellular phones should be turned off around some types of hospital equipment.

It is well known that a mobile device 200, such as, for example, a cellular telephone using the GSM standard, generates detectable radio interference. It is well known to users of GSM cellular telephones that if the cellular telephone is used in the vicinity of an electronic device (such as, for example, a radio receiver, stereo system, TV set, a wired/fixed telephone or even another GSM cell phone), the radio transmissions from the GSM cell phone may be inadvertently “picked up” by the electronic device and a signal proportional to the envelope of the radio transmission may be produced inside the electronic device. In fact, this typically unwanted signal may even disrupt the operation of the electronic device. For example, it is particularly well known that GSM cellular telephones present a potential hazard for wearers of heart pacemakers, as the GSM signal may disrupt proper pacemaker operation if the phone is very near to the wearer's chest.

In one embodiment, the sensor module 216 is configured to exploit the detectable radio interference of the electromagnetic signal 206 generated by the mobile device 200 when it is communicating with the cellular base station. When the sensor module 216 of the detector module 202 detects the electromagnetic signal 206, it assumes the presence of a mobile device 200 located within the detection zone 220, i.e., in or in proximity of the driver seat 106, and communicates a signal 212 to the control module 204. Disposed in communication with the control module 204 is a jamming module 218. In one embodiment, when the control module 204 receives the signal 212 from the detection module, the jamming module 218 transmits a jamming signal 214 via the antenna 210 that is detectable only by the mobile device 200 when located in the detection zone 220. In various embodiments, the electromagnetic jamming signal 214 may be a signal that disables the operation of the mobile device 200, may disable certain functionality of the mobile device 200, or may redirect the operation of the mobile device 200 to a hands-free operation. The control module 204 may be disposed in communication with a system of the vehicle 100, such as the ignition system 224, the gear box 226, or a variety of sensors 228. The control module 204 logic then monitors a function of a system of the vehicle 100 in addition to the detection of the presence of the mobile device 200. Accordingly, the jamming module 218 would be activated only when a monitored function of the vehicle 100 is activated. For example, when the sensor module 216 detects the presence of a mobile device 200 in the detection zone 220, the jamming module 218 would be activated only when the vehicle 100 is turned on, when the vehicle 100 is moved out of park or otherwise put in gear, or when one or more sensors detect that the operation of the vehicle 100.

In one embodiment, the sensor module 216 may comprise an energy harvester to harvest the energy in the electromagnetic signal 206 transmitted by the mobile device 200. The energy harvester receives the radiated energy at the antenna 208 and converts the energy into a voltage potential to energize the detector module 202 and communicate the signal 212 to the control module 204. In other embodiments, the energy harvester may be separate from the sensor module 216 and the voltage potential produced by the energy harvester may be used to energize the sensor module 216. In any embodiment, the voltage potential produced by the energy harvester is employed to determine the presence of a mobile device 200 in the detection zone 220. Accordingly, the sensitivity of the sensor module 216 is adjusted such that the energy harvester is sensitive only to the radiated energy levels that typically occur when the mobile device 200 is located within the detection zone 220 and not sensitive to electromagnetic energy transmitted by mobile devices 222 located outside the detection zone 220. In this manner, passengers can freely use their mobile devices 222 outside the detection zone 220 without triggering the detector module 202.

In other embodiments, the detector module 202 may be coupled to the electrical system of the vehicle 100 and powered by the vehicle battery, or may be powered by a separate battery. In such embodiments, the detector module 202 comprises a frequency scanning and power level measurement module that measures the power of the electromagnetic signal 206 transmitted by the mobile device 200. Accordingly, the sensitivity of the detector module 202 can be tuned to trigger the detection signal 212 when the detector module 202 detects transmit power levels that correspond to the mobile device 200 being located in the detection zone 220 without triggering the detection signal 212 for transmit power levels corresponding to the mobile devices 222 located outside the detection zone 220. This may be accomplished by strategically locating a directional multi-band antenna 208 such that it is maximally sensitive to transmit power level radiated by the mobile device 200 located in the detection zone 220 and minimally sensitive to transmit power levels to the mobile devices 222 located outside the detection zone 220.

In one embodiment, the control module 204 may comprise a communications jamming module 218 coupled to the antenna 210. The jamming module 218 is disposed in communication with the antenna 210. The antenna 210 emits a jamming signal 214 to thereby disrupt mobile device 200 signals and prevent or otherwise interfere with the ability to make or receive calls with the mobile device 200. The jamming module 218 and the antenna 210 may be powered by the electrical system of the vehicle 100, or may be powered by a separate battery. The jamming module 218 may be any device that transmits a jamming signal 214 that causes interference or inoperability of the mobile device 200. In some embodiments, the jamming module 218 may broadcast noise or a specialized signal that is selected to interfere with one or more of the communications frequencies of the mobile device 200. For example, the jamming module 218 may broadcast noise or a repeated interfering signal on the control channel frequencies for a cellular phone system. In some embodiments, the jamming module 218 may transmit on a narrow frequency band, while in other embodiments a very broad frequency band may be selected. The precise method for interfering with the mobile device 200 by the jamming module 218 is dependent on the transmission and reception characteristics of the mobile device 200. Those skilled in the art may use any appropriate jamming module 218 for any specific mobile device 200 device contemplated.

In accordance with one aspect, the jamming module 218 may be mounted in the vehicle 100. When activated, the jamming module 218 inhibits the ability to send or receive a mobile telephone call with a mobile terminal 200 located in the detection zone 220. Depending on the wattage of the jamming module 218 (or the use of a directional antenna), the zone in which the mobile device 200 is jammed may be controlled. Thus, for example, the jamming module 218 may be set to effectively jam telephone calls to or from the mobile device 200 for a space of 1-3 feet from the location of the jamming device 218, or in a direction which interferes with the ability of the driver to receive a telephone call, place a telephone call, or send a text message but not interfere with other passengers' ability to receive or initiate mobile telephone calls or send test messages.

In one embodiment, the antenna 210 may be positioned under the dashboard of the vehicle 100 or up on the driver side windshield. Alternatively, a directional antenna could be placed in the driver's seat to interfere with the driver making calls or sending text messages.

In one embodiment, the control module 204 may be used to prevent communications by the operator of the vehicle 100 when the mobile device 200 is detected in the detection zone 220 in combination with either an ignition switch, transmission switch, or other vehicular sensor mechanism. In one embodiment, an ignition switch may be monitored to cause the jamming module 218 to broadcast only when a mobile device 200 is detected in the driver seat 106 side of the vehicle 100 and the ignition switch is turned on, which would require the operator of the vehicle 100 to shut down the vehicle 100 to establish outside communications. The jamming module 218 would prevent any further communications until the vehicle 100 was switched off. In another embodiment, the jamming module 218 may be activated only when a mobile device 200 is detected in the detection zone 220 and an automatic transmission in the vehicle 100 is moved out of “park” and into a position where the vehicle 100 may move. When such a system is in place, the operator of the vehicle 100 must stop the vehicle 100 and either move the transmission to “park” or turn off the engine to operate the mobile device 200.

In one embodiment, the jamming module 218 may be configured to operate within the confines of the vehicle 100. In some cases, the antenna 210 coupled to the jamming module 218 of the control module 204 may be configured with a predetermined power level and directional attributes to direct the jamming signals 214 merely in the detection zone 220 such that other occupants of the vehicle 100 can continue to operate other mobile devices 222. In such cases, the jamming signals 214 may be generally confined within the detection zone 220 of the vehicle 100. In some embodiments, the jamming signals 214 may be localized to other areas within the vehicle 100 so that operation of a mobile device in that area is disabled, but leaving other mobile devices outside of that area operational.

In various embodiments, the antenna 210 and power level of the jamming signal 214 may be configured to deliver the jamming signal very precisely to the detection zone 220. In one embodiment, this may be implemented with a directional antenna located within the vehicle 100 where maximum jamming is delivered to the detection zone 220 and minimal jamming power is delivered outside the jamming zone 220. In such embodiments, the detector module 202 may be configured to indiscriminately detect any transmissions from all mobile devices 200, 222 within the vehicle 100 and the jamming module 218 would only transmit jamming signals to the detection zone 220 to jam the mobile device 200 within the detection zone 220 without affecting the mobile devices 22 outside the detection zone 220. Such implementation would not care whether or not a mobile device is located within the detection zone 220, thus simplifying the design of the detector module 202.

In one embodiment, the jamming module 218 may permit incoming calls to the mobile device 200 but prohibit outgoing calls to the mobile device 200. When the detector module 202 detects the energy in the electromagnetic signal 206 from an attempted outgoing call by the mobile device 200, the signal 212 activates the jamming signal 214. In such an embodiment, the detector module 202 may comprise additional modules to discern the identity of the mobile device 200 and enable the control module 204 to transmit the jamming signal 214 after the identity of the mobile device 200 is confirmed.

In other embodiments, the sensor module 216 may be used to detect and permit or deny any type of operation of the mobile device 200. For example, calls may be received by the mobile device 200 but placed calls may be jammed. In another example, some calls, such as emergency calls, may be permitted to be placed while other outgoing calls are jammed. Any other function of the mobile device 200 that may be detected may be selectively permitted or disabled by the jamming module 218.

In one embodiment, the mobile device 200 may receive the jamming signal 214 and operate in a reduced function mode. For example, the mobile device 200 may be prohibited from initiating a phone call except for emergency calls to 911. In another example, the mobile device 200 may be permitted to receive all calls or calls from a predefined list of callers while being prohibited from placing calls. Various reduced function modes may be used and in some embodiments a setting may define the precise operations allowed.

In one embodiment, control module 204 initiates the detection process by transmitting probing signals to detect the presence of a mobile device 200 within a detection zone 220. Once the probing signals are transmitted, the detector module 202 waits for an echo signal reflected by the mobile device 200 or a response signal transmitted by the mobile device 200. If the detector module 202 detects the echo signal or a transmission by the mobile device 200, the control module 204 transmits a control signal to control the operation of the mobile device 200. For example, in one embodiment, jamming module 218 transmits a control signal to disable the operation of the mobile device 200 by way of jamming signals 214 that interfere with the communication mechanism of the mobile device 200. In another embodiment, the control module 204 may reroute communications to a hands-free system, such as a Bluetooth communication system.

FIG. 3 illustrates one embodiment of a power sensor circuit 300 for detecting the energy radiated by the electromagnetic signal 206 transmitted by the mobile device 200. The illustrated power sensor circuit 300 is one embodiment of a sensor module 216 described in connection with FIG. 2. The power sensor circuit 300 also converts the energy in the radiated electromagnetic signal 206 to a voltage potential indicative of the location of the mobile device 200. In the illustrated embodiment, the power sensor circuit 300 is not connected to the power source of the vehicle 100 or to a separate battery. Rather, the power sensor circuit 300 is one implementation of an energy harvester circuit which derives its power only from the energy radiated by the electromagnetic signal 206 transmitted by the mobile device 200. The electromagnetic signal 206 detected by the antenna 208 is filtered by tuning circuit 306 to match the most common frequency bands used by mobile devices. In one embodiment, the tuning circuit 306 may comprise an inductor L and a capacitor C selected to tune the power sensor circuit 300 to the desired frequency band. Those skilled in the art will appreciate that the tuning circuit may be implemented using digital or analog tuning techniques and therefore the embodiment disclosed in FIG. 3 is not limiting.

The diode D_rf is an RF diode and acts to partially rectify the electromagnetic signal 206 received by the antenna 208 and tuned by the L-C circuit. The output of the RF diode charges a capacitor C_o to a predetermined potential V_d. Thus, the power sensor circuit 300 converts the radiated electromagnetic signal 206 to a voltage potential V_d that corresponds to the location of the mobile device 200 within the vehicle 100. With reference now to both FIGS. 2 and 3, when the voltage potential V_d across the output capacitor C_o exceeds a predetermined level, it indicates the presence of a mobile device 200 within the detection zone 220. The voltage potential V_d is compared to a threshold voltage V_t by a comparator 306. The threshold voltage V_t is predetermined as the voltage level corresponding to the mobile device 200 being located in the detection zone 220. The output of the comparator 306 is provided to a detection logic module 304, which may be part of the detector module 202. The detection logic module 304 then generates a detection signal 212 and communicates the detection signal 212 to the control module 204. Upon receiving the detection signal 212, the control module 204 activates the jamming module 218 to interfere with the operation of the mobile device 200. As previously discussed, in certain embodiments, the jamming module 218 may be activated only if other logical conditions are met such as the state of the ignition system, the gear box, or other sensors.

Still with reference to FIGS. 2 and 3, it may be desirable to determine when to shut off the jamming module 218. Accordingly, in one embodiment, once the V_d signal is provided to the control module 204, the detection logic module 304 activates a switch 302 to discharge the output capacitor C_o. Substantially at the same time, the jamming circuit 218 is turned off. If the mobile device 200 is still activated in the detection zone 220, the electromagnetic signal 208 would be picked up by the antenna 208 to charge the capacitor C_o and generate a voltage potential V_d to activate the jamming module 218. This cycle would be repeated until the mobile device 200 is either removed from the detection zone 220 such that the radiated electromagnetic signal 208 is too weak to activate the power sensor circuit 300 or the mobile device 200 is deactivated or shut off such that there is little or no radiated electromagnetic signal 208.

In the embodiment illustrated in FIG. 3, the tuning circuit 306 may be implemented to have a bandwidth encompassing the most popular cellular telephone frequencies. Since the tuning circuit 306 is fixed, it is tuned to a wide frequency band to receive electromagnetic signals 208 from about 0.8 to about 2 GHz, as shown in TABLE 1 below. In other embodiments, however, as described in connection with FIG. 4, the tuning circuit 306 may include a frequency band scanner to switch between multiple tuning elements and scan the detection zone 220 for multiple frequencies to more precisely tune the power sensor circuit 300 to the appropriate frequency band of the mobile device 200 located in the detection zone 220.

FIG. 4 illustrates one embodiment of a power sensor circuit 400 comprising a tuning circuit 406 with a scanner 402 in series with the antenna 208. The scanner 402 is controlled by the logic module 404 and sweeps multiple frequency bands. With reference now to FIGS. 2-4, the logic module 404 periodically switches tuning elements L₁, L₂, L_n, into the tuning circuit 406 to monitor various frequency bands associated with the mobile device 200 located in the detection zone 220. The voltage potential V_d is compared to a threshold voltage V_t by a comparator 406. The threshold voltage V_t is predetermined as the voltage level corresponding to the mobile device 200 being located in the detection zone 220. In other respects, the power sensor circuit 400 shown in FIG. 4 operates in a manner similar to the power sensor circuit 300 shown in FIG. 3.

FIG. 5 illustrates a schematic diagram of a multi-band detector 500 for monitoring uplink activity of the mobile device 200. In the illustrated embodiment, the multi-band detector 500 provides high-speed scanning of cell phone uplink frequency bands for CDMA, GSM, PCS, and WCDMA. An uni-directional multi-band antenna 508 receives signals 506 from a mobile device located in the detection zone 220. A scanner 510 continuously scans CDMA, GSM, PCS, and WCDMA frequency bands for mobile devices 200 located in the detection zone 220 that are in active or idle state. A detector module 502 provides a detection signal 512 to the control module 504 for activating a jamming module when a signal 506 is detected, as previously discussed. The up-link frequencies covered by the multi-band detector 500 shown in FIG. 5 are listed in TABLE 1 below.

The multi-band detector 500 may be implemented using a variety of components to detect radiated energy in the signal 506 received by the uni-directional multi-band antenna 508 and make RF power measurements at low levels by the detector module 502 in order to detect the presence of a mobile device 200 in the detection zone 220. The RF power level may be measured directly or may be sampled. Recently, a number of integrated RF power detectors have become available, intended for wireless networking and mobile telephone applications. Since these integrated circuits are produced in high-volume using integrated-circuit technology, they are consistent and inexpensive—often cheaper than typical microwave diodes, such as RF diode D_rf shown in FIGS. 3 and 4. Many of them are specified for operation into the GHz region, covering several amateur microwave bands, and a few operate to 10 GHz and beyond.

In one embodiment, the RF power detector module 502 may be implemented with an LTC5508 integrated circuit from Linear Technologies rated up to 7 GHz, which is well within the bandwidth required for mobile devices frequency bands shown in TABLE 1. This integrated circuit requires operate a few milliamps at 3 to 5 volts and would be connected to the power supply of the vehicle or to a separate battery. An LT5534 logarithmic-amplifier type detector rated up to 3 GHz with 60 dB of dynamic range may be employed to amplify the RF power signal detected by the LTC5508 integrated circuit.

The multi-band detector 500 may be employed to measure RF power transmitted by the mobile device 200 and also antenna radiation pattern measurement. The sensitivity of the multi-band detector 500 may be useful for low-level power measurements as an “RF Sniffer” to detect RF leakage from the mobile device 200. The multi-band detector 500 provides fast response so that it may be used to detect modulation and to detect noise levels from the multi-band antenna 506.

FIG. 6 illustrates an interior portion of the vehicle 100 comprising one embodiment of the mobile device detection and control system 102 located within the dashboard 108 of the vehicle 100. FIG. 6 illustrates three potential locations within the dashboard 108 where the mobile device detection and control system 102 can be located. It will be appreciated that the detection and control system 102 may be located in one or more of these locations on or within the dashboard 108. It would be preferable that the detection and control system 102 be located within the dashboard 108 to prevent user tampering. Accordingly, the detection and control system 102 is shown is phantom to indicate that the detection and control system 102 is located within the dashboard 108. In another embodiment, the control module 203 may be configured with a data collection process to record a situation when the detection and control system 102 was deactivated by an owner of the vehicle 100 with or without the help of a car mechanic. Such tamper recording and detection feature may be helpful in post accident investigations to determine if the detection and control system 102 was disabled and thus voiding insurance coverage, for example.

With reference now to FIGS. 1-6, the mobile device detection and control system 102 comprises a detector module 202 and a control module 204 coupled to the detector module 202. The detector module 202 detects the presence of a mobile device 200 within the detection zone 220 (“Discovery Umbrella”). When the detector module 202 detects the presence of a mobile device 200 within the detection zone 220, the control module 204 activates the jamming module 218, which transmits the control signal 214. The control signal 214 interferes with the operation of the mobile device 200 when it is located within the detection zone 220 without interfering with mobile devices 222 located outside the detection zone 220.

In one embodiment, the mobile device detection and control system 102 may be triggered when the driver enters the vehicle 100. Upon being triggered, the mobile device detection and control system 102 is initialized and goes into detection mode to establish a no-communication system (“NoCom system”). The detection mode is a process wherein the mobile device detection and control system 102, through one or more sensor(s) and logic detects the presence of all electromagnetic signals 206 such as RF, Wi-Fi, Cellular, and Satellite communications signals from the mobile device 200. In one embodiment, the detection process is initiated by the mobile device detection and control system 102, which is not dependent upon a driver's interaction to initiate the detection process. Decoupling the process from the driver, young and old, is advantageous because it avoids reliance on self policing, which currently has failed to work even with laws presently enacted. Thus, the triggering condition may be the activation of a switch such as the ignition switch 602 of the vehicle 100 or deactivation of a “park” sensor 604 of an automatic transmission of the vehicle 100, among other sensors.

Accordingly, upon ignition of the vehicle 100, the mobile device detection and control system 102 would initiate the detection process via logic that controls the operation of the detection module 202 and the control module 204. In accordance with the detection process, logic would instruct the sensor module 216 to initiate sensing or scanning for any type of communication signals 206 emitted by the mobile device 200 within the detection 220 within the driver side 106 area of the vehicle 100. In one embodiment, the sensor module 216 may be located within the dashboard 108 console and or within a microphone of a hands-free seta. This configuration would hide the sensor module 216 and prevent drivers from tampering with the mobile device detection and control system 102 by blocking the sensor module 216 or prevent activation of the detection process. In one embodiment, the sensor module 216 may be coupled to the ignition 602 to render the vehicle 100 inoperable if the sensor module 216 is blocked.

The logic provides a detection process for detecting communication signals 206 emitted by the mobile device 200 located within the detection zone 220 to prevent the driver from adequately using the mobile device 200. The detection process will detect and take control of the driver side mobile device 200. The logic, however, will not prevent passengers from using their mobile devices 222 outside the detection zone 220.

Once the detection process is initiated, if the mobile device 200 is a smart phone and is detected within the detection zone 220, in one embodiment, the mobile device detection and control system 102 can automatically connect to the vehicle 100 hands-free communication system. If no hands-free communication system is available, the mobile device 200 would be disabled by the control signals 214 transmitted by the jamming module 218. Nevertheless, the mobile device detection and control system 102 would always allow emergency 911 calls.

Additionally, once the detection process is initiated, if the mobile device 200 is a smart phone and is detected within the detection zone 220, in one embodiment, the mobile device detection and control system 102 is configured to disable inbound/outbound text messaging features of the mobile device 200. In one embodiment, all inbound text messages would be saved as is the case currently. In one embodiment, the mobile device detection and control system 102 is configured through logic to read back the text via the Bluetooth/hands-free system as well as reply via voice activated text via the Bluetooth/hands-free communication system. In such an embodiment, the jamming module 216 may communicate with the mobile device 200 through a secondary channel, such as a Bluetooth wireless connection or any other connection that is secondary to the primary cellular communication channel. In some embodiments, the jamming module 216 may communicate only on the primary communication channel of the mobile device 200 or in addition to one or more secondary cellular communication channels.

Moreover, once the detection process is initiated, if the mobile device 200 is a smart phone and is detected within the detection zone 220, in one embodiment, the mobile device detection and control system 102 is configured to disable inbound/outbound emailing features. In one embodiment, all inbound emails would be saved as is the case currently. The mobile device detection and control system 102 is configured through the logic module to read back the email via the Bluetooth/hands-free system as well as reply via voice activated email via the Bluetooth/hands-free communication system.

Furthermore, once the detection process is initiated, if the mobile device 200 is an iPad® or a Netbook® device and is detected within the detection zone 220, in one embodiment, the mobile device detection and control system 102 is configured to disable inbound/outbound text messaging/emailing features. All inbound emails would be saved as is the case currently. The mobile device detection and control system 102 is configured through the logic module to read back the email/text via the Bluetooth/hands-free system as well as reply via voice activated email/text via the Bluetooth/hands-free communication system.

FIG. 7 illustrates one embodiment of a logic diagram 700 for determining the presence of a mobile device located in a predetermined detection zone within a vehicle. With reference now to FIGS. 1-7, in one embodiment, the detection module 202 receives 702 a communication signal 206. The detection mule 202 determines 704 that the communication signal 206 was transmitted by a mobile device 200 located within a predetermined detection zone 220 within a vehicle 100. The control module 204 transmits 706 a control signal 214 to the mobile device 200 located within the predetermined detection zone 220.

In one embodiment, the detection module 202 transmits a detection signal 212 to the control module 204 when a voltage potential V_d substantially equals a predetermined threshold value V_t, wherein the voltage potential of the predetermined threshold value V_t indicates the presence of the mobile device 200 within the predetermined detection zone 220.

In one embodiment, the detection module 202 scans for a plurality frequency bands associated with the mobile device 200. The radiated power level of the communication signal 206 in the plurality of frequency bands received by the detection module 202 are monitored by the detection module 202. The detection module 202 transmits a detection signal 212 to the control module 204 when the measured radiated power level substantially equals at least predetermined value V_t.

In one embodiment, the detection module 202 harvests the energy in the received communication signal 206 and generates a voltage potential corresponding to the location of the mobile device 200 within the detection zone 220.

In one embodiment, the control module 204 monitors a functional system of the vehicle 100. The transmission of the control signal 214 is activated when the monitored functional system is activated and the detection module 202 determines that the communication signal was transmitted by the mobile device 200 located within the predetermined detection zone 220. In one embodiment, the functional system of the vehicle 100 is any one of an ignition system 224, a transmission system 226, and a sensor 228.

In one embodiment, when the control module 204 receives the detection signal 212, the control module 204 either jams the mobile device 200, jams at least one function of the mobile device 200, or redirects the operation of the mobile device 200 to a hands-free alternate system.

In various embodiments, the mobile device 200 may be configured to provide voice and/or data communications functionality in accordance with different types of wireless network systems or protocols. Examples of suitable wireless network systems offering data communication services may include the Institute of Electrical and Electronics Engineers (IEEE) 802.xx series of protocols, such as the IEEE 802.1a/b/g/n series of standard protocols and variants (also referred to as “WiFi”), the IEEE 802.16 series of standard protocols and variants (also referred to as “WiMAX”), the IEEE 802.20 series of standard protocols and variants, and so forth. Additionally, the mobile device 200 may utilize different types of shorter range wireless systems, such as a Bluetooth system operating in accordance with the Bluetooth Special Interest Group (SIG) series of protocols, including Bluetooth Specification versions v1.0, v1.1, v1.2, v1.0, v2.0 with Enhanced Data Rate (EDR), as well as one or more Bluetooth Profiles, and so forth.
