Patent number: 8092061Abstract: A display assembly includes a light pipe having re-directing channels defined therein. When a light source is provided in a compartment of the light pipe, light admitted from the light source to the light pipe emits from a front face of the light pipe. In addition, light emitted from reflective surfaces spaced apart from external surfaces of the light pipe combine with light emitted through the front face to provide glow regions of light resulting in symmetric uniform illumination of the display.Type: GrantFiled: April 15, 2009Date of Patent: January 10, 2012Assignee: Delphi Technologies, Inc.Inventors: Gail M. Sylvester, Raymond Lippmann, Martin L. Adams

Publication number: 20100265735Abstract: A display assembly includes a light pipe that has a front face adapted for emitting light to illuminate a display. The light pipe defines a compartment for receiving a light source. A light shield is disposed overlying the compartment. Channel segments are formed in the rear face and are symmetrical about the compartment. Light from the light source is extracted through the front face to create glow regions about the light shield, over the channel segments, and adjacent the edges of the light pipe. This results in symmetrically uniform illumination of the display while utilizing a single central light source.Type: ApplicationFiled: April 15, 2009Publication date: October 21, 2010Applicant: Delphi Technologies, Inc.Inventors: Gail M. Sylvester, Raymond Lippmann, Martin L. Adams

Patent number: 6623142Abstract: The invention adjusts the spectral characteristics of a light emitting diode (LEDs) by placing a filter in the LEDs light emission path. The filter is printed on the lens of the LED or printed on a cap that is later attached to the LED via ink jet printing or another printing method. The specific ink colors selected for the filter depend on the deviation of each LED from a specified tolerance. The filters create a high degree of color and intensity uniformity without requiring labor and cost-intensive binning.Type: GrantFiled: February 15, 2002Date of Patent: September 23, 2003Assignee: Delphi Technologies, Inc.Inventors: Ray Lippmann, Gail M.

Patent number: 6384592Abstract: An apparatus for minimizing angular rotor position errors in an air core gauge includes an air core gauge (105) having a magnetic rotor (108) and at least three coils (102, 104 and 106) wound around the rotor (108). A probe signal is applied to the first coil (102), and output signals are developed and detected across the second and the third coils (104, 106) in response to the probe signal and low-frequency signals applied to one or more of the coils (102, 104 and 106). The output signals are processed by a demodulation circuit (110) and a number of DC voltage signals are produced therefrom. A control circuit (304) is responsive to the number of DC voltage signals to determine an actual angular position of the rotor (108), and to suitably adjust the low-frequency signals to thereby correct for errors between the actual angular position of the rotor (108) and the desired angular position thereof.Type: GrantFiled: October 23, 2000Date of Patent: May 7, 2002Assignee: Delphi Technologies, Inc.Inventors: Gail M. Sylvester, Raymond Lippmann, James E. Nelson
