In response to receiving the detection code, the mobile device is paired with the wireless sensor device.
FIG. 1 illustrates a system 100 in accordance with an embodiment. The system 100 includes a wireless sensor device 102, a mobile device 104, and an application 106 coupled to the mobile device 104. One of ordinary skill in the art readily recognizes that the wireless sensor device 102 and the mobile device 104 can be represented by a variety of devices including but not limited to health monitoring sensors, cell phones, and cameras and that would be within the spirit and scope of the present invention. In addition, one of ordinary skill in the art readily recognizes that the wireless sensor device 102 can be represented by a variety of forms including but not limited to a patch.
In one embodiment, both the wireless sensor device 102 and the mobile device 104 are equipped with a sensor. One of ordinary skill in the art readily recognizes that the wireless sensor device 102 and the mobile device 104 can utilize a variety of devices for the sensor including but not limited to uni-axial accelerometers, bi-axial accelerometers, tri-axial accelerometers, microelectromechanical system (MEMS) tri-axial accelerometers, gyroscopes, and pressure sensors and that would be within the spirit and scope of the present invention.
FIG. 2 illustrates a flow chart 200 of a method for pairing a wireless sensor device with a mobile device in accordance with an embodiment. Referring to FIGS. 1 and 2 together, a code is provided within the wireless sensor device 102, via step 202. One of ordinary skill in the art readily recognizes that the code can be represented by a variety of codes including but not limited to an advertising packet with a unique signature or a bit set. In one embodiment, the code is an advertising packet with a tap_detected bit set.
The mobile device 104 is physically contacted against the wireless sensor device 102, via step 204. One of ordinary skill in the art readily recognizes that the contacting can be accomplished in a variety of ways including but not limited to a tapping between the mobile device 104 and the wireless sensor device 102 and a shaking of the mobile device 104 and the wireless sensor device 102 together for a predetermined time period and that would be within the spirit and scope of the present invention. In response to the contacting, the mobile device 104 receives the code from the wireless sensor device 102 and the pairing of the mobile device 104 with the wireless sensor device 102 is completed, via step 206.
In one embodiment, step 204 includes utilizing the application 106 coupled to the mobile device 104 to display an instruction to a user on how to perform the tapping and tapping the mobile device 104 at least twice against the wireless sensor device 102. One of ordinary skill in the art readily recognizes that the mobile device 104 can be tapped in a variety of different patterns against the wireless sensor device 102 to increase the fault tolerance including but not limited to tapping two times or tapping three times and that would be within the spirit and scope of the present invention.
In one embodiment, step 206 includes detecting the tapping motion by both the sensor within the wireless sensor device 102 and the sensor within the mobile device 104. In response to the detecting, the mobile device 104 scans for codes provided within devices within a predetermined proximity and the wireless sensor device 102 advertises the code to devices within a predetermined proximity.
In one embodiment, the wireless sensor device 102 only begins advertising the code in response to detecting the tapping motion and the mobile device 104 only begins scanning for codes in response to detecting the tapping motion. In one embodiment, the mobile device 104 scans for codes provided within the devices using a Bluetooth Low Energy scan mode and the wireless sensor device 102 advertises the code to the devices using a Bluetooth Low Energy advertise mode.
Once the mobile device 104 scans the wireless sensor device 102 that is advertising the code, step 206 further includes transmitting the code from the wireless sensor device 102 to the mobile device 104 and initiating a connection between the wireless sensor device 102 and the mobile device 104. In one embodiment, initiating a connection includes transmitting a connection request from the mobile device 104 to the wireless sensor device 102 and accepting the connection request by the wireless sensor device 102, wherein the mobile device 104 is paired with the wireless sensor device 102.
The tapping motion involves both the wireless sensor device 102 and the mobile device 104, so the detection results are fully synchronous. One of ordinary skill in the art readily recognizes that the time it takes starting from detecting the tapping motion on the wireless sensor device 102 and ending with the mobile device 104 receiving the code from the wireless sensor device 102 is typically short including but not limited to less than 100 milliseconds (ms) and that would be within the spirit and scope of the present invention.
In one embodiment, a predetermined time period for scanning the codes provided on the devices is implemented on the mobile device 104. In this embodiment, the code must be transmitted from the wireless sensor device 102 to the mobile device 104 within the predetermined time period. One of ordinary skill in the art readily recognizes that the predetermined time period can be a variety of different times including but not limited to 250 ms and that would be within the spirit and scope of the present invention.
By implementing the predetermined time period, the probability that the mobile device 104 will falsely recognize another wireless sensor device or will receive multiple codes is decreased. If the mobile device 104 does not receive the code from the wireless sensor device 102 within the predetermined time period or if the mobile device 104 receives a plurality of codes from various devices within the predetermined time period, then the application 106 coupled to the mobile device 104 aborts the pairing process and displays an error message to the user to retry the pairing process.
As above described, the method and system allow for a pairing of a wireless sensor device with a mobile device using a contacting motion. By implementing sensors within both the wireless sensor device and the mobile device and an advertising packet within the wireless sensor device, a contact between the wireless sensor device and the mobile device that causes a vibration is detected which initiates the transmittance of the advertising packet from the wireless sensor device to the mobile device to establish a connection between the two devices. The connection between the wireless sensor device and the mobile device is established efficiently and a cost-effective and fault tolerant wireless sensor device pairing system is achieved.
A method and system for pairing a wireless sensor device with a mobile device using a contacting motion has been disclosed. Embodiments described herein can take the form of an entirely hardware implementation, an entirely software implementation, or an implementation containing both hardware and software elements. Embodiments may be implemented in software, which includes, but is not limited to, application software, firmware, resident software, microcode, etc.
