Publication number: 20080111736Abstract: The present invention provides systems and methods that enable a standalone receiver capable of downloading navigation data under weak signal conditions. In an embodiment, a standalone navigation receiver generates predicted satellite orbits based on the tracking history of the satellites stored in the receiver. The tracking history comprises historical navigation data previously received from the satellites. The receiver uses the predicted satellite orbit to generate navigation data such as ephemeris and almanac. Since the predicted satellite is accurate, the generated navigation data is similar to the navigation data transmitted by the navigation satellites, and can therefore be used by the receiver to correct the downloaded navigation data bits. Thus many of the bits of a downloaded navigation word, especially the higher order significant bits of the word can be corrected. The remaining bit errors can be resolved based on a parity check of the word.Type: ApplicationFiled: November 10, 2006Publication date: May 15, 2008Inventor: Shaowei Han

Publication number: 20080111738Abstract: The present invention provides methods and system for enabling a standalone navigation receiver capable of generating receiver specific predicted satellite orbits based on historical navigation data collected by and stored in the receiver. Thus, the navigation receiver is able to use the predicted satellite orbits to obtain better Time-To-First-Fix (TTFF) and position accuracy without the need of connecting to a remote server and the associated communications system. In an embodiment, a standalone navigation receiver having sufficient memory collects navigation data from navigation satellites and generates predicted satellite orbits using the collected navigation data. Under weak signal conditions when decoding of the navigation data is not possible, the receiver uses the predicted satellite orbits to predict the accurate satellite positions or the set of ephemeris and the associated pseudoranges. The predicted orbits may be accurate for several days without the reception of broadcast ephemeris.Type: ApplicationFiled: November 10, 2006Publication date: May 15, 2008Inventor: Shaowei Han

Publication number: 20080111774Abstract: A scanner repeats a threshold voltage correcting process over a plurality of horizontal periods prior to the sampling of a signal potential to hold a voltage corresponding to the threshold voltage of a driving transistor reliably in a retentive capacitor. Each signal line is associated with a pair of switches, one for supplying the signal potential to the signal line and the other for connecting, to the signal line, a common line for supplying a reference potential. A signal selector turns on and off the switches in each horizontal period in timed relation to a line sequential mode to switch between the signal potential and the reference potential and selectively supply the signal potential and the reference potential to the signal line of each column.Type: ApplicationFiled: November 13, 2007Publication date: May 15, 2008Applicant: SONY CORPORATIONInventors: Yukihito Iida, Katsuhide Uchino

Publication number: 20080111776Abstract: An object of the present invention is to provide a light emitting device that is able to suppress power consumption while a balance of white light is kept, without making a configuration of a power source circuit complicated. A power source potential corresponding to each color of a light emitting element is used as a higher electric potential of a video signal and an electric potential of a power source line in the case that a transistor for controlling a supply of electric current to the light emitting element is a p-channel TFT. Conversely, a power source potential corresponding to each color of a light emitting element is used as a lower electric potential of a video signal and an electric potential of a power source line in the case that a transistor for controlling a supply of electric current to the light emitting element is an n-channel TFT.Type: ApplicationFiled: January 3, 2008Publication date: May 15, 2008Applicant: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.Inventors: Mitsuaki Osame, Aya Anzai, Ryota Fukumoto
