Synchronized, wrist mounted perimeter alarms

Abstract

An alarm, locating and tracking apparatus is provided for the prevention a dependent from being lost from a caregiver. A transmitter that carried by each are programmed with a safe distance demarcation such that when a dependent travels past such a distance, an audible alarm sounds on both transmitters. This alarm is intended to prevent the dependent from becoming lost. Should the alarm fail to prevent such an incident, a location signal is transmitted to a local cellular telephone towers or by low earth orbiting satellites used for low power communication. When an adult or child is lost or in danger, the transmitter which sends a signal to a central reporting station or stations to provide location information to aid in the caregiver's search. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

1. Detailed Description of the Figures

(10) Referring now to the drawings, wherein like reference numerals indicate the same parts throughout the several views, a wrist mounted tracking and locator device 10 is provided that is supported on a user's wrist by a wrist band 12. The wrist band 12 is formed of a transmitter module 14 supported with in the band 12 which extends as a pair of linearly elongated band members 12a, 12b adapted to circumscribe a user's wrist or ankle. Terminating each band member 12a, 12b are interlocking components of a wrist band locking means 16.

(11) The wrist band locking means 16 comprises a male insertion end 20 for inserting into a female retaining end 22. An encapsulated locking wire 30 encircles the band 12 and links the male insertion end 20 to the female retaining end 22 in order to prevent accidental or unauthorized removal of the transmitter.

(12) The wrist mounted tracking and locator device 10 is anticipated as being utilized in pairs, including a caregiver device 10a and a dependent device 10b. A local alarm perimeter distance L is provided that forms a demarcation distance for activation of a local proximity alarm. According to one aspect of the present invention, the local alarm perimeter distance L may be fixed or adjusted to a desired distance from a reference position. In the instance where the device 10 is being used in an indoor mode, i.e. inside a building or crowded area, the distance L may be referenced from a caregiver's device 10a. Alternately, in the instance where the device 10 is being used in an outdoor mode, i.e. while outside or on a trip or otherwise remotely away from the caregiver, the distance L may be referenced from a specified location (e.g. a building such as a school), or coordinate. According to yet another aspect of the present invention, the local alarm perimeter distance L may be adjusted utilizing a smart phone application 30, thereby allowing changes in the perimeter distance L to be modified through the use of a cell phone application in Bluetooth or similar wireless communication with the caregiver device 10a.

(13) Further, the pair of tracking and locator devices 10a, 10b are in wireless communication with one another, either through Bluetooth, WiFi or similar or equivalent wireless local area network. The perimeter distance L provides a demarcation between a non-alarm distance (i.e. distanceL) and an alarm distance (i.e. distance>L) such that when a distance between devices 10a and 10b exceeds the selected range, an audible alarm 32 incorporated within the transmitter module 14 is annunciated in a manner that cannot be terminated by the dependent device 10b itself, but rather only through an acknowledgment at the caregiver device 10a or through the smart phone application 30.

(14) Referring next to FIG. 4, a functional electrical block diagram of the associated circuitry as used with the wrist mounted tracking and locator device 10 is depicted. A radio frequency transmitter 50 provides an output signal to an antenna 55. The transmitter may use the 2.4 gigahertz, 3.6 gigahertz, 5 gigahertz or 60 gigahertz radio bands. The antenna 55 is envisioned to be of a loop type that may be embedded in the perimeter of the transmitting module 14, though it may be seen by those familiar in the art that other types such as microwave, dipole, multiple array and other type antennas will work equally as well and is not intended to be a limiting factor. A battery 65 provides input power to a voltage regulator module 70 as shown. In the event of low power output from the battery 65, an electrical signal is applied to the battery level indication light 40. It is envisioned that the voltage regulator module 70 would be capable of providing a sufficient advance warning that the battery 65 is depleted of power before the battery 65 ceases to function. Output power from the voltage regulator module 70 is applied to the radio frequency transmitter 50 and to an identification module 75. The identification module 75 is individually unique for each tracking apparatus 10 such that a signature is applied to the radio frequency transmitter 50 through a digital signal path 80 as shown.

(15) All components as shown in FIG. 4 are envisioned to be of the microminiature nature and perhaps combined by use of Very Large Scale Integration or future electrical assembly method still under development.

(16) Referring finally to FIG. 5, a flow diagram depicting the decision tree as used in determining the safety of a dependent utilizing the locating and tracking apparatus 10 is depicted. The process begins at a first operational block 120 which describes the process of waiting for a received first radio frequency signal 85 (as shown in FIG. 4). If no signal is received, a first functional block 125, by way of a negative response, dictates that the process continues. If a positive response results, it must be determined that the signal is from a transmitting module 14 (as shown in FIG. 4) that is not on an inactive list as shown by a second functional block 130. Such transmitting module 14 that would be on an inactive list would be those that are not assigned to a child, those that are lost, or those from a child that is known to be safe. If such a signal is received from those transmitting module 14 that are known to be inactive, a positive response indicates that the monitoring process should begin again at the first operational block 120. If a negative response is received at the second functional block 130, local monitoring personnel or equipment will contact the parents or authorized guardians as dictated by a second operational block 135. If, after conversation or input from a caregiver, it is determined that the dependant is not in danger, a negative response at a third functional block 140 dictates that the number corresponding to the said received signal be added to the inactive list as shown by a third operational block 145. The corresponding number will remain on the inactive list until the parent or authorized guardian calls the monitoring station 110 and reactivates the associated transmitting module 14. If a positive answer or no response is received at the third functional block 140, a fourth operational block 150 dictates that the appropriate law enforcement officials be contacted and assistance in locating the child as aforementioned described be provided.

2. Operation of the Preferred Embodiment

(17) To use the present invention, after purchase a caregiver would register the dependant along with the associated number of the locating and tracking apparatus 10 and corresponding transmitting module 14 with the monitoring station 110. Additionally, the demarcation distance L would be set and the system activated.

(18) As long as the distance between the devices 10a, 10b are within the alarm limit L, no action is needed or required. Once the dependant's device 10b is moved outside of the alarm limit L, an audible alarm 30 would annunciate in order to prevent the parties from losing track of each other. In the event that the prophylactic alarm fails to prevent the caregiver from being unable to identify the location of the dependant, the tracking signal via a radio frequency signal 85 is emitted to a local ground station 90 or a low earth orbit satellite 95 which would result in a land-based communication path 115 being established to a monitoring station 110 bearing the identification number of the respective transmitting module 14 and therefore the respective child.
