摘要:
An improved guidance system and method provide a packaged tour object having tour directions and media related to points of interest of a tour for playing via a telematics unit. A user is provided, via their telematics unit, with specific directions to access points of interest of the tour in a certain sequence, while the telematics unit optionally conveys media content to the user at appropriate points. The media content may be keyed to an upcoming site, and may comprise audio and/or visual information. In addition, user convenience information such as parking and ticketing information may be contained ion the packaged tour object for presentation via the telematics unit.

The described principles provide a method and system for identifying potentially closed roads and potentially open roads based on reroute requests, and of accommodating the potential road closure. If a reroute request is received from a user on a given route, the avoided roads of the route may be deemed potentially closed. If a predetermined number or a statistically significant number of users treat the road as potentially closed in this manner, it may be deemed closed. Similarly, if a supposedly closed road is chosen by a predetermined number of users, as evidenced by reroute requests, then the supposedly closed road may be deemed to be open. Moreover, observation of reroute requests also allows the system to automatically learn a user's route preferences.

A system for a vehicle navigation accurately calculates travel times between locations and serves a vehicle driver request for the shortest time route. A navigation server compiles data of common road segments between two locations that are contained in route requests and subsequently calculates travel time between the two locations. When subsequent route requests contain further information pertaining to the same locations, the navigation server updates the travel time. Consequently, the navigation server can calculate the travel times of different routes from the same source vehicle location and destination location. When a vehicle driver requests directions from the vehicle's current location to a destination, the navigation server then provides directions for the shortest time route to the vehicle driver.

摘要:
A system of converting oxygenate-containing feedstock to light olefins comprises charging a reactor with catalyst, feeding the feedstock into the reactor, contacting the feedstock with the catalyst and converting the feedstock to olefins while depositing byproducts on catalyst resulting in spent catalyst, regenerating the spent catalyst by combustion gases, and stripping the regenerated catalyst of gases entrained in the regenerating step. The stripping step is accomplished using nitrogen gas to strip the entrained gases from the regenerate catalyst. In one embodiment, regenerated catalyst is passed through a regenerated catalyst stripper before it is returned to the reactor.
摘要:
A receiver (1100) includes a direct digital frequency synthesizer (130), a mixer (105), and a clock source (1110, 1130). The direct digital frequency synthesizer has an input terminal for receiving a first clock signal at a first frequency, and an output terminal for providing a digital local oscillator signal synchronously with the first clock signal. The mixer (105) has a first input terminal for receiving a radio frequency (RF) signal, a second input terminal coupled to the output terminal of the direct digital frequency synthesizer (130), and an output terminal for providing an IF signal having a spectrum centered about a selectable one of a plurality of center frequencies. The clock source (1110, 1130) has an output terminal for providing the first clock signal without using a harmonic frequency that overlaps the spectrum for the plurality of center frequencies.
摘要:
A electrical housing knockout device (4) having a bracket (5) with a horizontal side (7) perpendicularly secured to a vertical side (6) and a sleeve element (8) connected to the horizontal side (7). The sleeve element (8) includes a shaft (9) and a base (10) wherein a central opening (12) extends through the shaft (9) and base (10). The sleeve element (8) also includes a collar (11)located between the shaft (9) and base (10) wherein the collar (11) has an aperture (14). The sleeve element (8) extends from the collar (11) at a predetermined angle. The collar (11) is adjacent to the horizontal side (7) and is positioned such that the collar aperture (14) is pivotal about a stopper (15) which extends from the horizontal side (7). A means for securing the bracket (5) to the interior of a junction box (1) or circuit breaker box (26) is also included.

A fuel system for a mobile platform is provided. The system includes a crossfeed fuel transmission assembly having a single crossfeed valve that controls fuel consumption from a first fuel tank and a second fuel tank. The system additionally includes a balancing fuel transfer assembly fluidly connected to the crossfeed fuel transmission assembly. The balancing fuel transfer assembly includes a plurality of fuel balancing valves for controlling a transfer of fuel to the first and second fuel tanks. The fuel system further includes a fuel balancing controller for automatically controlling the fuel balancing valves to automatically control the transfer of fuel to the first and second fuel tanks.

A tuner (200) includes a direct digital frequency synthesizer (206) and a mixer (220). The direct digital frequency synthesizer (206) has an output terminal for providing a digital local oscillator signal having a frequency chosen to mix a desired channel to baseband. The mixer (220) has a first input terminal for receiving a tuned radio frequency signal, a second input terminal coupled to the output terminal of the direct digital frequency synthesizer (206), and an output terminal for providing an in-phase baseband signal.
摘要:
A television tuner (920) is adapted for use in a television receiver (900) that receives a radio frequency (RF) signal from an input device (910) and outputs audio and video information from a selected channel in response thereto. The television tuner (920) includes a direct digital frequency synthesizer (206) and a mixer (220). The direct digital frequency synthesizer (206) has an output for providing a digital representation of a mixing signal. The mixer (220) has a signal input for receiving a television signal, a mixing input coupled to the output of said direct digital frequency synthesizer (206), and an output for providing an intermediate frequency (IF) television signal.
