Patent number: 10920942Abstract: A rear facing light bar assembly that incorporates a plurality of light functions in a small integrated unit. A multifunctional circuit board powers different colored light emitting diodes to produce the tail light, brake light, amber and/or backup light. The assembly also has end caps, a one-piece polycarbonate tube lens and an extruded housing. Heat from the circuit board is dissipated through the end caps and into the extruded housing. The assembly is constructed such that the electronics are completely protected from the outside environment, and sealed from water and dust intrusion. The light also minimizes tooling and assembly cost, yet provides a secure seal protecting the electrical components. In addition, the light is serviceable so individual parts can be replaced or repaired if parts are damaged.Type: GrantFiled: April 22, 2019Date of Patent: February 16, 2021Assignee: Bestop Baja, LLCInventors: Alan R. Roach, Christopher C. Johnson

Patent number: 7789544Abstract: A modular light rack assembly for off-road vehicles having a plurality of individual pieces that can be selectively connected to form a substantially linear assembly for attaching a variety of headlight subassemblies. In each embodiment, there is a common left hand mounting configuration and common right hand mounting configuration, so that each piece of the modular light rack assembly having one or both of these configurations on its end or ends is selectively connectable to any other piece to form a substantially linear assembly of any desired configuration.Type: GrantFiled: October 10, 2007Date of Patent: September 7, 2010Assignee: Baja Designs, Inc.Inventors: Alan R. Roach, Stephen J. Mitchell

Patent number: 7249875Abstract: A light rack assembly for off-road vehicles capable of surviving high vibration loads generated in off-road racing. Each assembly comprises at least one headlight sub-assembly having a center of gravity that, when mounted to the frame of the light rack assembly, resides in a spherical zone defined by the effective radius of the light and the mounting points of the light housing. Each light is isolated from vibration of the vehicle and can be individually adjusted to the preference of the driver without tools. The light rack assembly can be quickly removed from the vehicle, or be mounted such that the assembly can be rotated to adjust the light beams while the vehicle is in motion and rotated to retract the assembly to protect the lights when not in use.Type: GrantFiled: April 15, 2005Date of Patent: July 31, 2007Assignee: Baja Designs, Inc.Inventors: Alan R. Roach, Stephen J. Mitchell

Patent number: 5551391Abstract: A series of method and apparatus advances in the accumulator-type fuel injector art, applicable to both intensified and unintensified accumulator injectors, which cooperate to provide major improvements in internal combustion engine fuel economy, reduction of noise, and reduction of undesirable exhaust emissions, including smoke, oxides of nitrogen and hydrocarbons. According to the invention, injector needle closure speed is increased for sharper fuel cutoff and better atomization proximate closure and needle closure bounce is minimized to minimize fuel dribble proximate closure by reducing both mass and length of the needle, which can be accomplished by a longitudinally divided needle. Hydraulic damping also damps and cushions both needle closing and needle opening.Type: GrantFiled: September 3, 1993Date of Patent: September 3, 1996Assignee: Servojet Electronic Systems, Ltd.Inventors: Niels J. Beck, James A. Pena, Alan R. Roach, Bevan H. Johnston

Patent number: 5537972Abstract: A pressure intensified fuel injector incorporates an overtravel safety feature which prevents fuel flow through the high pressure chamber of the intensifier upon injection nozzle failure, thereby preventing further and uncontrolled injection events in the event of such failure. The overtravel safety feature is preferably formed by dimensioning the high pressure plunger of the intensifier such that, upon overtravel of the plunger in the event of injector nozzle failure, a side surface of the plunger blocks a fuel inlet port of the high pressure cylinder of the intensifier, thereby preventing further fuel flow through the high pressure cylinder. The intensifier having the overtravel safety feature can be used in either accumulator-type or non-accumulator-type injectors.Type: GrantFiled: July 28, 1994Date of Patent: July 23, 1996Assignee: Servojet Electronics SystemsInventors: Niels J. Beck, James A. Pena, Alan R. Roach, Bevan H. Johnston

Patent number: 5467754Abstract: A method of reducing undesired premixed burning in an internal combustion engine includes lifting an injector needle of a fuel injector a constant low-lift increment from a valve seat of a valve covers orifice (VCO) nozzle having an injection hole opening into the valve seat, and preventing lifting of the needle beyond the low-lift increment for a sufficient interval of time to inject a relatively small initial fuel charge into the engine from the VCO nozzle, the injection producing a highly atomized, wide-angle spray plume with relatively low penetration. The interval terminates when lifting forces imposed on the needle overcome holding forces imposed on the needle by a stop plate which has opposed first and second surfaces exposed to an ambient fluid pressure and to a fluid vapor pressure, respectively. A subsequent step includes lifting the needle to a higher lift position to inject a main fuel charge into the engine, the main fuel charge being injected as a relatively narrow jet having high penetration.Type: GrantFiled: September 7, 1993Date of Patent: November 21, 1995Assignee: Servojet Electronic Systems, Ltd.Inventors: Niels J. Beck, James A. Pena, Alan R. Roach, Bevan H. Johnston
