摘要:
A fuel injection system for an internal combustion engine includes an air suction pipe, a throttle valve located in the pipe, and a member, upstream of the throttle valve, which is actuatable by air flowing through the suction pipe so as to move a piston valve to dose a quantity of fuel to a fuel injection nozzle. The system includes a duct which bypasses the throttle valve, the duct having a valve which closes the duct when the throttle valve is closed and when the engine is above the idling speed. Dosing of fuel is thereby stopped during coasting of a vehicle, leading to decreased fuel consumption.

The invention relates to a fuel injection rotary piston internal combustion engine of the trochoidal type with a housing made up of a peripheral portion and two side walls and with a first injection nozzle in the peripheral portion and a second injection nozzle in the inlet port, which are connected to a fuel metering device and of which the delivery quantities are adjustable. A fuel delivery device continuously injects a quantity of fuel proportional to the air intake and is in permanent communication with the first nozzle. Control means connect the second nozzle to the fuel delivery device only from a predetermined part-load up to full load conditions.

A design is presented for an NxN crossbar switch. A crossbar switch is one of the basic components of Optical Switching Networks. An optical NxN switch has the capability of connecting any light beam from the input of the switch to any output port of the switch without interfering with other light beams. That is each single input is connected to one and only one of the output ports without interfering with any other beam or beams. The design presented is based on the use of precision meso-sale mechanics of the size typically found in miniature disc drives and meso-scale optical components. This meso-scale mechanics is then controlled or driven by precision servo-electronics and software to achieve the correct switching. The precision servomechanisms, meso-scale mechanics, electronics and software control are designed to work together to self-compensate for assembly or manufacturing defects and deleterious environmental, including temperature, effects.

Systems and techniques are described for distributed control and coordination of autonomous agents in a system. A protocol for distributed control allows autonomous agents to negotiate a group task for the agents, such as locomotion or self-reconfiguration in a robot application, and to synchronize individual agent actions to effect the group task. A protocol for adaptive communication allows autonomous agents, such as physically coupled self-sufficient robot modules, to continuously discover changes in their local topology. In general, in one implementation, the technique includes: discovering a local topology, which includes a type of a communication connection to autonomous agents in the reconfigurable network topology, and determining an action based upon a received control message and the determined local topology.

A holding device holds a camera rearward of an ocular of a glass such as a monocular or binocular to record an image utilizing the camera. The image is made available by the glass. This holding arrangement is usable with many cameras and binoculars or monoculars. A rapid change between the camera positioned forward of the ocular and a cleared ocular is made possible for the direct viewing by the user through the glass (binocular or monocular).

A movie antipirating scheme associates a detector with a screen and takes video and/or pictures of the audience. The detector can either detect something emitted by the camera or can find an image of a camera in the audience. An output indicative of the location of the probable camera can be used to find the person using the camera in the audience. Eg by detecting his seat number if sitting down or location if the camera has been stashed somewhere. Most likely the camera in front and center to avoid obvious distortion in the features the movie
摘要:
In a frequency translator for r-f television signals and the like there is provided an input frequency selective matching network to pass only r-f television signals in a predetermined range of about 50 to 300 MHz (vhf), a novel combination oscillator, impedance matching network, and mixer arranged for mixing incoming television signals from a cable or antenna with a preselected reference signal of a constant frequency generated by the oscillator to produce output signals from the mixer in a higher band of frequencies of about 500 to 750 MHz (uhf). An output frequency selective matching network passes only signals in said second band of frequencies to an output terminal. The impedance matching network provides a conjugate match for the output impedance of the oscillator and the input impedance of the mixer so as to inhibit the reflection of undesirable signal products from the mixer back to the oscillator and minimize power loss. The output frequency selective network and mixer arrangement do not require an active gain stage and an associated additional frequency selective matching networks in an input circuit ahead of the mixer.
