Patent number: 9299320Abstract: Techniques for providing visual feedback on a display of an electronic device by sequentially and/or independently controlling the illumination of the lighting output by the display. In some implementations, the techniques may be employed following an interaction with the device having one or more light source controllers instructing one or more light sources, such as Light Emitting Diodes (LEDs), in a lighting apparatus, such as for a display which renders content on the device. For instance, a lightguide of the lighting apparatus may sequentially receive light from the one or more light sources as directed by the one or more light source controllers and may direct the light to provide illumination for a display. In some cases, the display may be a reflective display that is front-lit by the lighting apparatus. In other cases, the display may be a backlit display that is backlit by the lighting apparatus.Type: GrantFiled: February 20, 2014Date of Patent: March 29, 2016Assignee: Amazon Technologies, Inc.Inventor: Siddharth Gupta

Patent number: 9097825Abstract: A front light component for electronic devices that include displays for rendering content using a light guide to control illumination for a front light display. A high reflectivity “white” tape is used under and adjacent to the light guide to improve overall uniformity of the light beams. The high reflectivity tape may also be selected to be of a controlled white hue to compensate for variances in color of Light Emitting Diodes (LEDs) where the LED color is slightly off from ideal white. In this way the complementary color of the high reflectivity tape with the color of the LED will cause the output spectrum to be uniform and white. This disclosure also describes techniques for assembling electronic devices in a component stack to provide enhanced display uniformity and improved reading experience.Type: GrantFiled: June 24, 2013Date of Patent: August 4, 2015Assignee: Amazon Technologies, Inc.Inventors: Siddharth Gupta, Gregory Turner Witmer

Patent number: 8693267Abstract: A system and a method to improve signal synchronization in a plurality of signal paths traversing multiple voltage domains. According to an embodiment of the present disclosure a memory arrangement is preferred for signal synchronization. All read/write and clocks signals and other control signals are driven to periphery supply (Vp) levels, except wordline (WL[i]) signals which are driven at core supply (Vc) level. By doing so, lower average and peak current consumption associated with core supply (Vc) is achieved with constant delays and maintaining required signal synchronization in the signal paths traversing multiple voltage domains.Type: GrantFiled: December 23, 2009Date of Patent: April 8, 2014Assignee: STMicroelectronics International N.V.Inventors: Siddharth Gupta, Rakesh Kumar Sinha, Vamsi Krishna Gullapalli, Dibya Dipti

Patent number: 7508691Abstract: A memory arrangement, particularly a ROM, having memory cells, local virtual supply voltage lines, word lines and result lines may also include global virtual supply voltage lines that run along the width of the memory arrangement parallel to the word lines. The local virtual supply voltage lines run parallel to the result lines, and perpendicularly to the word lines where the each local virtual supply voltage line runs only within a block of the memory arrangement. Each global virtual supply voltage line, in each block through which it runs, is connected to one local virtual supply voltage line. The coupling capacitance between the supply voltage lines and the result lines, and the inherent capacitance of the supply voltage lines are reduced, reducing the power consumption and increasing the clock frequency of the memory arrangement.Type: GrantFiled: October 26, 2005Date of Patent: March 24, 2009Assignee: Infineon Technologies AGInventors: Siddharth Gupta, Yannick Martelloni
