Bicycle brake light with graduated deceleration dependent lighting
First Claim
1. A bicycle brake light system comprising:
- a light assembly unit having a rearward facing multi-bulb display;
an adjustable swivel arm attached to said light assembly oriented inward toward a rear wheel spoke;
a pickup sensor housed within the adjustable swivel arm at a point most distal to said light assembly unit;
an open and closable hatch on top of said light assembly unit for insertion of a battery power source;
a switch installed on a most outward portion of the light assembly for activation of an on/off switch;
a magnet which is attached to a rear wheel spoke m such a manner as to allow for optimal detection by the pickup sensor;
a point of attachment to a bicycle frame of a bicycle via “
C”
clamps and positioned as to allow for sensor reception of said magnet; and
a PLC interface between the pickup sensor and a multi-bulb display that receives wheel revolutions, records time, and uses those as inputs to calculate discrete rates of deceleration and displays this information through activation of a plurality of rear-ward facing bulbs in a graduated manner based on differing degrees of deceleration based on logic pre-programmed into the PLC (Programmable Logic Controller).

Abstract
A bicycle brake light system with a graduated light display that is activated as a direct result of and in correlation with the degree of bicycle deceleration. The brake lamp lights are illuminated in a graduated sequence resulting from a predetermined range from slight deceleration to hard breaking that is conveyed visually through the number and color of illuminated lamps. The brake lamp assemblage interface calculates deceleration algorithmically through a magnet and sensor receptor and receiving programmable logic controller that receives, computes, and conveys a bicycle wheel'"'"'s decreasing revolutions per unit of time optically through illuminating lights to fellow vehicle operators and pedestrians.

9. An interface between a sensor and illuminable lights which forms a Programmable Logic Controller (PLC) unit which utilizes number of revolutions per unit of time (measured in seconds or tenths of seconds) on a wheel of any circumference to determine rates of negative acceleration where a positive number indicates acceleration and a negative number indicates deceleration or slowing and said rates of negative acceleration are used to determine an appropriate number of exterior illuminable lamps to activate based on a following acceleration and deceleration calculation formula:
-
Rate of acceleration=RPScurrent(T)−
RPSprevous(T-1)Where RPS is number of wheel revolutions per second, and T=current time, and T−
1=the current time minus 1 second (prior reading). - View Dependent Claims (10, 11, 12, 13)
