Abstract: A latching device is provided for releasably retaining in an upright and open position, a hinged door which is typically manufactured of a heavy cast iron and hinged to a train stop housing, thereby to prevent the unintentional and accidental closure of the hinged door during installation connections or any field operational maintenance of the train stop housing. Preferably, a latch assembly is mounted atop a sturdy frame which provides an integral support above the train stop housing and is mountable with mounting hardware to a mounting lug of the train stop housing. The latch assembly includes a covered latching bar which slides in a channel defined by a first and second bracket and is urged by a spring mounted between the first and second bracket, thereby to urge a latch end of the latching bar outwardly away from the latch assembly and an opposing handle end of the latching bar inwardly towards the latch assembly. The latching device is mounted to the train stop housing so that a hinged door which is rotated toward the integral support of the frame slides against the latch end and urges the latch end inwardly toward the latch assembly against the urging of the spring, until the door is moved past the latch end and the spring snaps the latch end outwardly away from the latch assembly, thereby to obstruct the door from unintentionally and accidentally being closed past the latch end, so that the door is positioned between the latch end and the support of the frame. When closing of the door is desired, the handle end of the latching bar may be manually grasped, thereby to urge the handle end outwardly away from the latching assembly and to retract the latch end inwardly towards the latch assembly to clear the latch end obstruction which prevents closing of the door.

Abstract: The invention relates to a digital data transmission system with a circuit- switched data connection (V.110) between a transmitting party (A) and a receiving party (B) the nominal data transmission rate of which may vary during the call. A sliding-window data flow control protocol is used on the data connection, in which a number of transmitted data frames to which the transmitting party (A) has not received an acknowledgement from the receiving party (B) is not allowed to exceed the size of the sliding window. In accordance with the invention, a unit (MSC) in the data transmission system that changes the nominal data transmission capacity (data transmission rate) of a non-transparent data connection notifies the change to the transmitting part y (A) and to the receiving party (B). This information enables the receiving and transmitting parties to change the size of the sliding window in a controlled manner.

Abstract: For convergence setting, a projection television set contains photosensors (S) for the primary colours R, G, B which supply an output signal (U1) in the event of impingement of a marker (M) contained in the projected picture. The time characteristic of the output signal of the sensor while the marker sweeps over is significantly steeper and shorter for the colour blue than that for the colours green and red. This reduces the complexity of the evaluation circuit.        An integrating element lies in the path of the output signal (U1B) of the sensor (S) for the colour blue and is dimensioned in such a way that the time characteristic of the output signal of the sensor (S) for the colour blue is approximately equal to the time characteristic of the output signals (U1RG) for the colours red and green. As a result, the time characteristic becomes identical for the signals of all three sensors and the circuit is simplified.        In particular for a projection television set with convergence setting using a plurality of sensors.

Title: Mobile location estimation in a wireless system using designated time intervals of suspended communication
Inventor: VANNUCCI GIOVANNI
IPC: H04W64/00
Filed: 1998-06-22
Granted: 2002-10-15
Abstract: Methods and apparatus for estimating mobile location in a wireless communication system including a plurality of base stations. In a base-to-mobile embodiment, the system base stations periodically transmit location signals to mobile stations during a system-wide blank-and-burst interval during which normal wireless communications are suspended. The interval is made sufficiently short that disruption to normal operation is negligible. Each base station transmits a distinct location signal which can be identified by a mobile station as associated with a particular base station. A given mobile station for which a location estimate is to be generated detects location signals from at least three of the system base stations. The detected location signals are used to generate differential path delay measurements which may be further processed in accordance with a triangulation technique to generate an estimate of mobile location. The suspension of normal wireless communications permits the location signals to occupy a broad bandwidth corresponding to multiple voice data channels, such that high resolution differential path delay measurements can be generated. The location signals from adjacent or neighboring base stations may also be configured to appear mutually orthogonal at a receiving mobile station, such that location signals from base stations close to a mobile will not interfere with detection of a location signal from a more distant base station. For example, the location signals may be selected to have waveforms which exhibit substantially non- overlapping comb-like frequency spectra. The invention may also be implemented in partial system blanking embodiments and mobile-to-base embodiments.

Abstract: An electrical receptacle includes a housing that is de-fined by identical nonconductive housing halves which are held in side-by-side assembled relationship by a metal mounting bracket.      The mounting bracket carries a ground wire connection screw that extends through a rear wall of the housing and threads into a threaded rear end region of a metal post which extends centrally through the housing to provide a threaded front end region confi-gured to receive a cover plate mounting screw. Two nonconductive rotors are journaled by the housing for independent rotation be-tween "off" positions and various "on" orientations for selective-ly supplying electrical energy to sets of female contacts that are carried by the rotors. A leaf spring is carried within the hollow interior of the housing for engaging detent formations of the ro-tors for releasably retaining the rotors in "off" and "on" orien-tations. The rotor carried contacts have front end regions that are configured to receive and conductively engage the metal prongs of conventional male plugs, and rear end regions that are confi-gured to selectively engage forwardly facing conductive surfaces provided on at least one circuit board which is carried within the hollow interior of the housing near the rear wall of the housing.      Wire connection terminals carried on opposite sides of the housing deliver electrical energy to the electrically conductive surfaces of the circuit board. Crimpable formations provided on the metal mounting bracket and/or the metal post may be utilized to maintain the assembled relationships of components of the receptacle.

Abstract: A method of and apparatus for analyzing a stream of ions first subjects a stream of ions to a first mass analysis step, to select ions having a mass-to-charge ratio in a first desired range; this enables a mass analyzer with high resolution to be used. The selected ions are then passed into a radio frequency linear ion trap containing a gas. The trapped ions are caused to collide with the gas, either by being injected with a high axial energy or by application of external excitation to cause fragmentation. Fragment ions of a given mass-to-charge ratio can then be isolated and excited to produce fragments of fragments. This process can be repeated to give multiple steps of mass spectrometry, MS n. The fragment ions, and undissociated precursor ions are then passed out of the linear ion trap and subjected to a further mass analysis step, for example in a time of flight device, to determine the mass spectrum of the ions.

Abstract: A multiplex system for multiplexing packets into ATM cells to be transmitted, which can implement effective use of channels corresponding to irregular traffic qualities in services with various types of quality conditions in an actual environment. In response to a connection establishment request (S402), current required bandwidths B1, ..., Bm are changed to B'1, ..., B'm by adding the new connection, which causes bandwidths X1, ..., Xm which are assigned to the channels to be changed. When the desired bandwidth including the requested connection is less than an available bandwidth of the corresponding channel, an assigned bandwidth change processing (5406) is .activated to assign new bandwidths in accordance with desired bandwidths. The bandwidth assignment change is carried out by changing ratios of extraction rates of packets from the buffers in the multiplex system.
