Title: Device control with topology map in a digital network
Inventor: CHILAMAKURI CHENCHU L
IPC: G06F3/0482
Filed: 1997-06-20
Granted: 2004-01-13
Abstract: A topology map for a system is generated and displayed on a display device to indicate the various components which make up the system. The various components are indicated using icons each of which represent a respective one of the components. When a device is added to the system, a graphical image representing that device is automatically displayed in a graphical user interface. Similarly, when a device is removed from the serial bus, the graphical image representing that device is grayed out, leaving a shadow of the graphical image until the device is either re-coupled or the system is powered off. In a preferred embodiment, a user specifies a source device and a receive device is manipulating the corresponding icons so as to cause a data transfer between the source device and the receive device. In another embodiment, one or more task windows are included in the interface which help the user select the task to be performed. Once selected, controls, commands and data related to the task are displayed within a control display window of the graphical user interface. When a task requires data to be sent between devices, the flow of data between the devices over the serial bus network is graphically represented by an animated data stream within the graphical representation of the bus structure.  When the data stops flowing between the devices, the animated data stream disappears. Data transfer operations may include the transfer of video data, audio data, or both. In a further preferred embodiment, the digital network corresponds to the IEEE 1394 Serial Bus Standard.

Granted: 2005-10-11
Abstract: Fuel-air mixture apparatus (1) has a body (2) adapted for connection via a flange (3) to an air cleaner housing (3') and to an engine inlet manifold (4'). In the body (2) is arranged a primary air passage (5) having an inlet (6), an adjustable throttle (7), a throat (8) and an outlet (9). The throttle will be connected in use to a speed control device for the engine via a linkage (10). Also provided in the body (2) is a secondary air passage (13) having an inlet (14) from the air cleaner housing and an outlet (15) to the primary air passage (5) at the throat (8). Towards its down-stream end, the secondary air passage opens into a chamber (16), with the opening (17) being arranged tangentially to the chamber to induce swirling air flow in the chamber. The outlet (11) is provided axially of the chamber. At the other end of the chamber, in a bore (18) in the body a nozzle device (21) is provided. It has a circumferential void (24) to the body. This void has a fuel supply bore (25) in the body (2) and connected to a continuous fuel pump opening into it. A fuel inlet (26) leads from the void to an internal bore in the sleeve (22). Slidably mounted in the sleeve is a guide (27), sealed to the sleeve via a gland (28). The outside end of the guide carries a compression spring (29) and the end of the guide is closed by a plug (30) providing an abutment for the spring, whereby the guide is urged outwards. The guide has a bore (31) in which a needle (32) is slidably mounted. The arrangement is such that when the plug (30) is pushed fully inwards of the body, as on closure of the throttle, the need le closes the aperture (38) and the fuel supply to the engine, but the force with which the needle is urged into the aperture is regulated by t he internal spring (33). In use, the plug (30) is acted on by an abutment member (40), which is movable in step with the throttle (7) via a branch of the linkage (10). The linkage is designed to ensure that the stoichiometrically required amount of fuel is provided for the throttle opening.

Granted: 2004-01-27
Abstract: A measuring or security system (1) for detecting the distance between an object (2) or a person (2) from a given point of reference, comprising a first transmitter/receiver device (10) enabling production of and wireless transmission of a control signal to a separate second transmitter/receiver device (30) and reception of an acknowledgement signal transmitted by the second transmitter/receiver device (30) on receiving control signal. Both transmitter/receiver devices (10,30) have a signal source (24,24,25,26) producing pulses as a control signal or an acknowledgement signal. Said pulses have a monotonously decreasing or increasing frequency during pulse duration or are made of overlapping pairs of like pulses. The other transmitter/receiver (10,30) has at least one dispersion filter (11) with a given frequency dependent signal transit time on its receive side so that received pulses can be time-compressed. Transit time is adapted to the modulation on transmit side in such a way that spectral signal components of the control or acknowledgement signal coincide substantially at dispersion filter output (11) as a result of varying frequency-dependent signal transit-times through said filter and appear thus with slight temporal imprecision.
