Patent number: 8669988Abstract: A data interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range “serial” type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.Type: GrantFiled: March 10, 2005Date of Patent: March 11, 2014Assignee: QUALCOMM IncorporatedInventors: Jon James Anderson, Brian Steele, George Alan Wiley, Shashank Shekhar

Publication number: 20130271471Abstract: This is directed to efficiently identifying alternative display attributes for displaying text in a display region when default display attributes are inadequate for displaying the text. Many electronic device user interfaces are designed based on text in a default language. When interfaces are translated for use in other languages, the translated interfaces can include words or phrases that are longer than the corresponding text in the initial language. To quickly find an adequate, alternate display attribute for the longer text (e.g., a new font size), the electronic device can calculate assumed reduced text box sizes for displaying the text should display attributes of the text be reduced. The electronic device can select an adequate reduced text box, and reduce the display attributes by an amount corresponding to the reduced text box.Type: ApplicationFiled: June 7, 2013Publication date: October 17, 2013Inventor: Brent Schorsch

Publication number: 20130050223Abstract: Before reducing a font size of a Chinese character, a to-be-adjusted standard radical is determined according to a non-neighboring outline ratio of a standard radical, and a radical serial list is established for the to-be-adjusted standard radical in a font database, for the purpose of consecutively updating the to-be-adjusted standard radical in the future. While the Chinese character is reduced by its font size, a radical serial list corresponding to the to-be-adjusted standard radical is first searched. The to-be-adjusted standard radical is then updated into a transformed radical step-by-step according to the radical serial list. At last, the transformed radical is used for replacing the to-be-adjusted standard radical to generate a transformed character, so as to achieve the effect of fine-tuning the Chinese character having the reduced font size.Type: ApplicationFiled: August 14, 2012Publication date: February 28, 2013Inventors: Fu-Sheng Wu, Yi-Hui Huang

Patent number: 6927773Abstract: The invention provides a font processing device. In font enlargement, a target font to be enlarged or reduced is divided into columns or rows, and a cost is calculated based on the pixel pattern formation for each column and row. In enlargement processing, a cost represents a line segment volume, and a column or a row that has low-cost, that is, has a pixel array close to a line segment, is difficult to be enlarged. Further, in reduction processing, a cost represents a degree of likeness to an adjacent column or row, and a column or a row that has a similar pixel pattern is reduced with priority. In practice, the column or row for the target font is decided based on the pixel formation of the target font for enlargement or reduction so that natural enlargement/reduction can be obtained. In addition, font modification is executed by using enlargement and reduction of the font.Type: GrantFiled: August 27, 2003Date of Patent: August 9, 2005Assignee: Seiko Epson CorporationInventors: Yukinobu Momozono, Takashi Kurumisawa

Patent number: 6377262Abstract: Image data processing and image rendering methods and systems whereby images are displayed on display devices having pixels with separately controllable pixel sub-components. Images, such as text characters, are displayed on a display device with at least some features being rendered with sub-pixel precision. The displayed advance width of a character displayed with sub-pixel precision is compatible with the advance width of the character if it had instead been displayed with a conventional full pixel precision rendering process. Thus, characters are displayed with sub-pixel precision, resulting in improved resolution and readability, while the advance width and the corresponding size and spacing of the characters and the overall formatting of the document remains the same compared to documents and characters rendered using conventional full pixel precision processes.Type: GrantFiled: April 10, 2000Date of Patent: April 23, 2002Assignee: Microsoft CorporationInventors: Gregory C.
