Patent number: 11710398Abstract: A system includes a processor and a memory. The memory stores program instructions executable by the processor to make a first determination to provide light to operate a vehicle and, based on the first determination, actuate a first set of lights. The memory stores program instructions executable by the processor to make a second determination to provide a communication, and, based on the second determination, actuate a second set of lights to provide the communication.Type: GrantFiled: January 26, 2018Date of Patent: July 25, 2023Assignee: Ford Global Technologies, LLCInventors: Albert Ekladyous, Lisa Hohmann, Udayakumar Ramasami, Kelley Maria Adams-Campos, Sarbjit Singh, Ghassan E.

Patent number: 9970623Abstract: A vehicular signal assembly that includes an inner chamber defined by a substrate comprising LED light sources and spaced apart, corresponding Fresnel lenses; and an outer chamber defined by the Fresnel lenses and an outer lens comprising optical elements. The outer lens can have a width of at least 12 mm. Further, each LED source emanates incident light directly through the chambers to produce a light pattern with a contrast ratio of 3:1 or less, e.g., a daytime running light pattern. Each LED source can also emanate incident light directly through the corresponding Fresnel lens an outer lens to produce the daytime running light pattern.Type: GrantFiled: September 19, 2017Date of Patent: May 15, 2018Assignee: Ford Global Technologies, LLCInventors: Gary Edward Henige, Chad Clement, Udayakumar Ramasami

Patent number: 9956903Abstract: A vehicle spot or floodlight system includes a vehicle rear-mounted light source such as a backup light array configured to emit light at a first intensity and at another intensity that is different from the first intensity. Emission of light at the another intensity is caused by an actuator operatively associated with the rear-mounted light source. A controller selectively allows the actuator to cause the emission at the another intensity. The controller allows the actuator to cause the emission of light at the another intensity only on receiving a signal indicating that the vehicle transmission is in a park or on receiving a signal indicating that the vehicle ignition is set on run, accessory, or off. The controller resets the actuator to off after a predefined time period when the ignition system is set on accessory or off, or when the transmission is placed in drive.Type: GrantFiled: October 19, 2015Date of Patent: May 1, 2018Assignee: FORD GLOBAL TECHNOLOGIES LLCInventors: Srihari Prasad Gondhi, Sleiman N. Abdelnour, Udayakumar Ramasami, Stephen Kenneth Helwig, Li Yan

Patent number: 9346396Abstract: A supplemental vehicle lighting system that is responsive to a trailer backup assist system is provided. The system includes a rear vehicle fixture defining a keylock hole customarily used in conjunction with a corresponding keylock cylinder. A light assembly is provided in the place of a keylock cylinder and operably coupled to the keylock hole. The light assembly includes a housing having a barrel that is concentrically aligned with the keylock hole and includes a distal end and a proximal end. A lighting device is disposed inside the housing and operable to emit light through the barrel beginning from the proximal end. A lens is coupled to the distal end of the barrel and is disposed to at least partially coincide with the keylock hole, wherein the lens is configured to disperse light emitted from the lighting device to illuminate a rear vehicle area.Type: GrantFiled: January 23, 2014Date of Patent: May 24, 2016Assignee: Ford Global Technologies, LLCInventors: Christopher Scott Nave, Thomas Edward Pilutti, Chad Clement, Udayakumar Ramasami, Sleiman N.
