Title: Spark ignition engine with pressure-wave supercharger
Inventor: WENGER URS
IPC: F01N3/24
Filed: 1997-03-03
Granted: 2004-09-07
Abstract: The invention relates to a spark ignition engine (1) having a pressure-wave supercharger (5) and a three-way catalyst (4). To remove the pollutant constituents HC, CO and NO x in an efficient manner, an oxidation catalyst (12) is connected downstream of the three-way catalyst, said oxidation catalyst being arranged between the outlet of the supercharger and the exhaust (11). The oxidation catalyst can, consequently, function with excess air which comes from the supercharger. The above combination reduces pollutants substantially with a high specific output of the engine.

Abstract: There is provided a video conferencing system (10) for enabling multiple, remotely located transceivers (12A, 12B) to communicate with each other, including transceiver (12) that utilizes different communication formats or protocols. The video conferencing system includes a telecommunications interface unit (20) and a plurality of transceiver (12) that may connect to the telecommunications unit (20) through telephone (14) or network links (22).  The telecommunications interface unit (20) includes a gateway block (24) corresponding to each transceiver (12) connected to the unit (20) and a switching subsystem (30) for directing communications, particularly video and audio information, between the gateway blocks (24). The transceivers (12) communicate with their respective gateway blocks (24) using their own communication formats, but the gateway blocks (24) communicate to the switching subsystem using a single common language, such as a standard television signal using the NTSC standard. Accordingly, the present invention permits multiple transceivers (12A, 12B) using different communication formats to communicate with each other effectively and efficiently.

Title: Variable rate transmission and reception methods, and variable rate transmission and reception devices
Inventor: OKUMURA YUKIHIKO
IPC: H04J13/18
Filed: 1998-05-15
Granted: 2004-02-10
Abstract: A transmission method for implementing variable rate transmission. Part of the baseband processing of a transmitter based on a CDMA transmission scheme is described. A transmitted information sequence in the form of a digital signal is phase modulated by a phase modulator 105. An orthogonal code generator 101 selects, in response to rate information of the transmitted signal, the orthogonal code to be generated. The bit rate of the orthogonal code the orthogonal code generator 101 generates is double the maximum transmission rate. The modulated transmitted signal is multiplied by the orthogonal code corresponding to the rate information with a multiplier 103. The transmitted signal, which is multiplied by the orthogonal code corresponding to the rate information, is further multiplied by a spreading code sequence with a multiplier 104 to be spread into a CDMA signal, and is transmitted under power transmission control based on the rate information. A receiving side can detect the rate without information about the transmission rate.

Abstract: The present invention generally provides a threaded tamper-evident closure having an annular hook-shaped flange (16) extending radially inward from the inner surface of the tamper-evident band (15) attached to the bottom edge of the closure body. The hook-shaped flange can be continuous or segmented and forms an upwardly angled surface f or engaging the sealing flange (17) on the bottle neck. A plurality of elevated areas (35) extend upwardly from the tamper-evident ban d in spaced relation to the bottom edge of the closure body. The frangible elements (14) connecting the tamper-evident band to the lower edge of the closure depending annular flange may be configured to extend from these elevated areas as well as the non-elevated areas of the tamper-evident band. Pairs of cooperating ratchets (38a, 38b) may be used in lieu of or in combination with the elevated bridge areas to reduc e the stress placed upon frangible elements and/or during cap application. A second preferred embodiment of the present invention provides a threaded tamper-evident plastic closure having a tamper-evident band containing the above-described features, for use with a tamper-evident push-pull resealable pour spout (20) which is substantially leak proof. The present invention also optionally provides a dust cover (90) which encloses the push-pull pour spout closure when inserted on the container. The dust cover may be optionally provided wi th a tamper-evident sealing band (91) which remains intact upon initial installation of the dust cover onto the container and which is broken when the dust cover is initially disturbed. When the dust cover is provided with a tamper-evident sealing band, the use of a band on t he lower edge of the pour spout closure for providing tamper-evidence may be eliminated.

Abstract: In order to avoid errors inherent in the measurement of electrical phase or pulse arrival time in relative group delay measurements, different optical signals have their intensity modulated at a common high frequency, different permutations are selected, their amplitudes detected, and phase differences between the signals are computed on the basis of trigonometrical relationships between amplitude and phase. In one embodiment, two optical signals are provided with continuous wave modulation at the same high frequency, transmitted along different optical paths, and detected individually and in combination. Following conversion to corresponding electrical signals, the amplitudes corresponding to the individual signals and combined signals, are measured and used to compute phase differences between the two optical signals. The computation relies upon trigonometrical relationships to extract the phase differences. Because the frequency of the modulation is known, the time differences can be deduced. Conveniently, apparatus for measuring the phase differences comprises a slotted wheel or other selection device which passes different selections of the optical signals, the first signal alone, the second signal alone, and both together. One of the optical signals may be split to produce a third signal, and a known propagation delay, preferably corresponding to about 90 degrees at the modulation frequency, introduced into the path taken by the third optical signal. The amplitudes of seven possible permutations of the three optical signals then are used to compute the phase difference. The phase difference measurements may be made for a plurality of different physical variables of one or more of the optical signals or the paths taken thereby, and used to compute, for example, chromatic dispersion, polarization mode dispersion, elongation, and so on.

Abstract: A highly scalable, flexible, and extensible mechanism is provided for authenticating a request from a client. In a preferred embodiment, the invention comprises an authentication engine, an authentication host, a plurality of providers coupled to the host which implement selected authentification schemes, and a machine independent communication mechanism which enables the various components to communicate with each other irregardless of the machine each component resides on. The communication mechanism enables the invention to be distributed, which in turn, makes the invention highly scalable. In operation, the authentication engine receives a request having associated therewith a protect string. The protect string specifies the authentication scheme or schemes that need to be implemented for that request.  The authentication engine parses the protect string into one or more provider requests, and sends the requests to the authentication host.  In response, the host forwards the requests to the appropriate providers for processing. The results of the providers' processing are sent back to the authentication engine, which then processes the results according to the protect string to determine whether the request has been authenticated. With the present invention, it is possible to add providers to the system, or to substitute a new provider for an existing provider, without changing or recompiling any other component in the system.  It is also possible to change the authentication schemes associated with a request by simply changing the protect string. These aspects of the invention make it possible to change implementation at deployment time, as opposed to compile time. This makes the invention highly flexible and extensible.
