Patent number: 10419772Abstract: Systems and methods for decoding compressed data are described herein. A memory may receive a data stream comprising a string of encoded symbols encoded using an arithmetic coding based coding technique. The string of encoded symbols represents a series of one or more decoded symbols. Each of the one or more decoded symbols comprises one of a most probable symbol and a least probable symbol. A processor may determine a number of consecutive most probable symbols in the series of one or more decoded symbols by performing a plurality of parallel mathematical comparisons based on one or more of the encoded symbols. The processor may further decode a group of symbols of the series of one or more decoded symbols based on the plurality of parallel mathematical comparisons. The group of symbols comprises the number of consecutive most probable symbols.Type: GrantFiled: October 28, 2015Date of Patent: September 17, 2019Assignee: QUALCOMM IncorporatedInventors: Pavel Sinha, Mark Todorovich

Publication number: 20110316832Abstract: Electromechanical devices such as MEMS can be controlled by “drive schemes” comprising electrical signals applied to the display to cause selective actuation or release of the electromechanical devices. In some drive schemes, all pixels on a line are released during a phase when a release voltage is applied along the common line. In some invention embodiments, the release phase sets the common line voltage to the maximum segment drive voltage for a portion of the release phase and the minimum segment drive voltage for the remainder of the release phase. This ensures that all electromechanical devices have a resulting voltage of zero during a portion of the release phase sufficient to release the devices without regard to the segment line voltages. This scheme eliminates slow and no release problems and also eliminates the need for additional voltage transitions on the segment lines.Type: ApplicationFiled: June 24, 2010Publication date: December 29, 2011Applicant: QUALCOMM MEMS Technologies, Inc.Inventor: Mark Todorovich

Publication number: 20060147888Abstract: An electronic handheld tutorial device having a display, an input element, a memory and a processor. The memory contains databases to enable a user to prepare for a test. The processor processes inputs from a user received from the input element and administers the test and provides a complete diagnostic analysis for the results of the test on the display.Type: ApplicationFiled: January 6, 2005Publication date: July 6, 2006Inventors: Christopher Burghardt, Toshihide Hokari, Christopher Cappuccio, Mark Todorovich

Patent number: 5497474Abstract: A number of memory locations are reserved in computer memory to store pointers which indicate an address within streams of sequentially arranged data. The data stream to be scanned is selected. To scan the information stored within the data stream, a single register is provided to increment the pointer corresponding to that data stream. The pointer information is then incremented and stored into the reserved memory location. The process of selecting, scanning, incrementing, and storing may repeat for each data stream to which access is sought.Type: GrantFiled: February 25, 1993Date of Patent: March 5, 1996Assignee: Franklin Electronic Publishers, IncorporatedInventor: Mark Todorovich

Patent number: 5396606Abstract: A hand held electronic data processing device has an input keyboard and a display screen. A sixteen bit central processing unit (CPU) address bus addresses read only memory (ROM) and random access memory (RAM). However, a twenty bit register provides a twenty line address bus that is employed for addressing sequential data in ROM. A direct memory access (DMA) unit provides direct transfer of data from RAM to a forty bit register which controls the state of the pixels in a 240 character liquid crystal display (LCD). The keyboard is connected in an electronic matrix with rows driven by signals applied by system address bus lines. These various functions require exclusive use of the system address bus.Type: GrantFiled: July 31, 1991Date of Patent: March 7, 1995Assignee: Franklin Electronic Publishers, IncorporatedInventors: Robert L. Grieb, Mark Todorovich
