Abstract:
A wearable proximity warning device called SIMS (Surrounding Intelligent Motion Sensor) is provided that uses a novel method of processing images from a high frame rate digital camera to detect human threats from behind and determine if there are any approaching threats by using novel pixel counting and threat detection analysis algorithms. The device is worn on the back of the body either by use of a belt clip or with chest straps. The user may use select from a variety of warning options from the device including audible warning tones, device vibration or smartphone SMS/MMS text messaging. Stored video is saved by the SIMS device and may be periodically uploaded to secure cloud storage. The device contains a rechargeable battery that may be recharged using a USB port.

Claim (Index 1):
A wearable device for detection and warning of approaching threats from behind comprising:\n a housing consisting of a front and a rear housing that mate together to form the exterior of said device; a clip mechanism rigidly attached to said rear housing for providing a means of attachment to an article of clothing worn on the body; slotted apertures located on the left and right sides of said housing for providing a means of attachment to the body using a chest strap; slotted apertures located on said front housing for providing a means of sound projection from an internal speaker; a motherboard that uses a threat detection algorithm to detect an approaching human threat and controls the activities of separate boards including an audio board, a vibration device, a smartphone communications board and a camera control board; said threat detection algorithm comprising:\n a human recognition detection algorithm that identifies humans from captured images; \n a human to pixel count conversion algorithm that converts the total number of pixels from humans identified from said human recognition algorithm and represents said identified humans as a number of pixels; and \n a threat determination algorithm that determines a threat condition based on an increase in number of pixels from said detected humans identified from said human recognition detection algorithm; \n the audio board that connects to a speaker and provides an audio warning tone to said speaker when activated by said motherboard; the vibration device that provides a means of vibration of said device when activated by said motherboard; a switch at the front face of said device for selection of either an audio based warning or a vibration warning for warning the user of an approaching threat; a button at the front of said device for activation of a Bluetooth wireless smartphone communication link; a button for turning power on or off to said device; a rechargeable battery for supplying power to the internal electronic components of said device; a battery recharging board for periodic recharging of said rechargeable battery; a USB port for providing a means to supply DC power to said battery recharging board; a smartphone communications board to send approaching threat warning messages to at least one linked smartphone by wireless means using either SMS or MMS text messaging; an antenna connected to said smartphone communications board for wireless transmission of SMS or MMS text messages to at least one linked smartphone; a camera control board for providing focusing and aperture control of a digital camera lens; a digital camera adjustable focus lens and variable aperture controlled by said camera control board; an image sensor using CCD (charge coupled device) technology to receive focused images from said digital camera lens; a GPS receiver to send GPS location data of said device to said motherboard; and an image processing board that receives digital images from said image sensor.
