DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] With reference to the attached illustrations, and initially FIGS. 1-2, the present invention discloses a visual front alert system (generally at 10) for instructing pedestrians or other drivers (collectively observers) as to the movement of a subject vehicle. As will be further described, the alert system is attached or incorporated into any of a forward facing location of the vehicle, such as including but not limited to a vehicle grille or adjoining license plate in an aftermarket type application, in order to indicate to observer(s) located forward of the subject vehicle whether the vehicle is maintaining a given speed or is decelerating/accelerating, this further indicative of either of a braking or other non-constant motion condition.

[0021] The alert system includes a main body 12, such as without limitation be constructed of a plasticized material having a four sided rectangular cross sectional shape and which can be flexible or rigid to varying degrees (hereinafter referenced as a semi-rigid material). Each of FIGS. 1 and 2 depicting a pair of elongated bodies 12 depicted in a stacked arrangement with the understanding that the elongated track shape of the body can be varied in any fashion desired. The illustrated embodiment depicts the body 12 defining an interior for receiving the circuitry and motion control components (e.g. including each of PCBA and accelerometer components) along with the illuminating elements, and over which is sonically welded or otherwise secured a light transmitting (this including any of transparent or translucent) cover 14, further best shown in FIG. 2. The enclosed circuitry also includes other functionality not limited to thermal management, mechanical/electrical functions and the like.

[0022] Any of a single or plural stacked arrangement of illuminating elements (see as will be further described in reference to FIGS. 3-5) is integrated within the elongated body such that illumination of the elements and is visible through the forward facing translucent or transparent cover 14. The illuminating elements can, without limitation, include one or more individual strips of such as LED elements (the term LED or illuminating element being interchangeably referenced), with wiring connections (see harness at 16 in FIGS. 1-2) including one or more connectors 18 secured to the plastic main bodies 12 and communicated to a processor (PCBA), not shown, incorporated into the assembled body for operatively controlling the illuminating elements.

[0023] An electrical power supply is provided to the strip shaped body and, in a first application, includes additional connections extending between the PCBA and a battery of the vehicle (not shown) connected to a remote end of the harness 16. In a further application, a portable battery (not limited to any of 12V, Lithium Ion or Nickel Cadmium) can be substituted for a dedicated hookup connection for powering the PCBA, accelerometer and illuminating elements/LEDs.

[0024] Powering options for the assembly also contemplate utilizing the vehicles onboard diagnostic port (OBD), which is again defined as a location where a diagnostic computer is connected, and operates to diagnose and read the trouble codes from the vehicle. The most common location for the OBD port is under the steering wheel on the driver's side. Another common place is near the center console panel, and sometimes even under the dashboard on the passenger side. The present invention also contemplates connecting any of ITM (Information Technology Management), OEM (Original Equipment Manufacturer) and aftermarket devices to the OBD port, such as which can also interface with the present assembly in order to increase both its functional and operational applications.

[0025] As is further known, the LEDs are a subset of electroluminescent lamps, generally defined as devices which convert electrical energy into light or luminescence, with the term luminescence generally associated with solids that generate light. In the case of electroluminescence, an electric field (voltage) applied to a thin phosphor layer produces light. Without limitation, the LEDs can be substituted with any other suitable illuminating elements within the scope of the present invention.

[0026] As is further understood, the PCBA component can incorporate an accelerometer component, which can also be incorporated directly into the PCBA 18. As best shown in the illustrations provided (again FIGS. 1-2), the wiring connections 16 are split into subset pluralities extending through each of individual illuminating strips, it being understood that additional embodiments can be substituted for that shown and contemplate any of the use of a single connecting strip, other multiple connecting strips or of substituting the wiring connections and associated connecting strips entirely in favor of any wireless connection not limited to Bluetooth?, NFC (near field communication) or other short range wireless connectivity technology configured between the PCBA and accelerometer to the individual LEDs/illuminating strips.

[0027] In this fashion, the PCBA instructs the visual output (illumination) of some or all of the LEDs/illuminating elements based on the vehicle movement sensed by the motion control circuitry/accelerometer. As is further known, the accelerometer is a device that measures the vibration, or acceleration of motion of a structure. The force caused by vibration or a change in motion (acceleration) causes the mass to squeeze the piezoelectric material, which produces an electrical charge that is proportional to the force exerted upon it. Since the charge is proportional to the force, and the mass is a constant, then the charge is also proportional to the acceleration.

[0028] In this manner, an accelerometer works using an electromechanical sensor to measure dynamic acceleration, defined as non-uniform acceleration forces when compared to its previous state. The theory behind accelerometers is that they can detect acceleration and convert it into measurable quantities like electrical signals.

[0029] In one non-limiting operation, the PCBA instructs a first visual output by the illuminating elements representative of a first steady or accelerating movement condition (this generally representing to the forward located observer that the vehicle is traveling a steady motion), with a second instructed visual output further representative of a decelerating or braking condition of the subject vehicle (additional visual outputs can also represent other non-constant travel conditions such as for vehicle acceleration).

[0030] The visual outputs envisioned by the present invention can include a number of different representations presented by the LEDs or other suitable electroluminescent elements, a first of which can include providing the first output in a first color (such as including but not limited to white), with the second output provided in a second color (such as further including but not limited to yellow or amber). It is further envisioned and understood that the first and second visual representations can be provided according to any of varying illumination intensities, flashing patterns, or the like, such further utilizing any of multiple different colors or a single color.

[0031] With reference now to FIG. 3, an illustration is shown generally at 20 of a further variant of a visual display assembly having a housing containing any individual or stacked pair of stacked LED strips (see white at 22 and amber at 24). As previously described, the housing can again include a two piece arrangement with a cavity defining and multi-sided elongated plastic base (at 26) over which is sonically welded or otherwise secured a further elongated plastic translucent or transparent cover 28.

[0032] As further shown in the side cutaway view of FIG. 4, this taken along line 3-3 shown in FIG. 3, the sealed assembly depicts the stacked LED strips 22/24 in combination with the circuitry components integrated into the housing including the PCBA (at 30) incorporating the motion control circuitry/accelerometer component (further representatively depicted at 32). Without limitation, additional envisioned variants contemplate substituting a two-piece sonically welded construction with a silicone injection molded arrangement encapsulating the LED strips 22/24 and associated PCBA/accelerometer components 30/32.

[0033] FIG. 5 presents an illustration of a plurality of sub-divided LED segments (see as represented at 34, 36, 38, 40 and 42), such as which can be incorporated into each of the strips 22/24. In one non-limiting application, the individual segments are illuminated via signals from the processor (PCBA) 30 according to any alternating or succeeding pattern, such as in order to provide any animated scheme or pattern according to any of a single (e.g. white) or multiple (e.g. white/amber colors are illuminated based on the inputs delivered to the motion control circuitry. The outputted lighting sequences can also include the segments being successively illuminated in a following or tracking manner, such as in a given direction, again in response to a given input condition from the PCBA/accelerometer, in order to instruct the forward located observer as to the travelling condition of the vehicle. The lighting patterns contemplated herein can further include, without limitation, the processor illuminating the LED's according to any of single or multiple lights, flashing or illuminating intensity.

[0034] A corresponding process for creating a visual front alert system attached to a vehicle includes each of the steps of providing each of a plurality of illuminating elements configured in a strip and a processor incorporating a motion control circuitry, forming a body around the illuminating elements and processor, communicating a power supply operating the processor and illuminating elements and, in response to a travel condition of the vehicle by causing the motion control circuitry, outputting a signal to the processor which is representative of the vehicle movement for signaling to the illuminating elements to generate a visual output corresponding to the signal. Additional steps including forming the body around the illuminating elements and processor, this further comprising securing a light transmitting cover over a multi-sided and cavity defining base. Other steps include injection molding a silicone material around the processor and illuminating elements and providing a wire harness extending from a battery of the vehicle and connecting an end of the harness to a location of the body.
