Abstract: A lightweight sideframe having a solid and open, unitary cross-sectional I-beam shape, is structurally improved by strengthening both sides of the sideframe with cross-bracing at each pedestal jaw area. The cross-bracing laterally stiffens the sideframe, eliminating the succeptability to twisting of the I-beam shape when a transverse load is experienced. The increased lateral stiffness at the jaw area also strengthens the total lateral strength of the sideframe, allowing some removal of metallic mass from the sideframe spring seat plate. The improved lateral sideframe strength also contributes to an increase in the threshold speed of truck hunting.

Abstract: A system for reducing bandwidth of video signals.  Ordinarily, an NTSC (National Television Standards Committee) video signal has (a) a bandwidth of 6.0 MHz, (b) chrominance and luminance carriers separated by about 3.58 MHz, and (c) an audio carrier located at the upper end of the 6.0 MHz bandwidth.  The invention reduces the separation between chrominance and luminance carriers to about 2.15 MHz, and decreases the bandwidth to about 4.0 MHz.  In addition, the invention moves the audio carrier outside the 4. O-MHz bandwidth.  The invention allows multiple channels, of 4.0 MHz bandwidth each, to be placed adjacent each other in a cable television spectrum, and the audio signals of the channels to be placed together, at the upper end of the spectrum, outside the range allocated to the video information.  A larger number of channels is obtained than would otherwise be available, because the upper end of the spectrum is not suitable for carrying video information, but will handle audio information.

Granted: 2008-09-09
Abstract: Dans la communication AMRC, une station de base détecte une différence entre une phase de référence d'un code de dissémination et une phase de signal reçu de chaque station de terminal, et alimente un signal de saut de phase PJ-i représentatif de la différence de phase de retour vers chaque station de terminal. Après l'acquisition de la temporisation, l'opération de réception est effectuée à l'aide de la phase de référence et un décalage entre la phase d'un signal reçu et la phase de référence est envoyé en retour à chaque station de terminal comme information de contrôle de synchronisation de phase PC-i. Chaque station de terminal règle approximativement la phase du code de dissémination selon le signal de saut de phase PJ-i, et règle ensuite précisément la phase de son signal de transmission conformément à l'information de contrôle de synchronisation de phase PC-i. Il est par conséquent possible de synchroniser les phases des signaux transmis à partir des stations de terminal et reçus à la station de base. Ainsi, un code orthogonal est utilisé pour les disséminer sur les liaisons inverses.

Title: Methods and apparatus for increasing the uplink gain for a cdma base station
Inventor: ZAPPALA CHRISTOPHER F
IPC: H04B1/707
Filed: 1998-04-30
Granted: 2001-07-31
Abstract: An improved CDMA base station for insuring a constant supply of energy to each of a plurality of rake fingers, thus improving gain. One aspect of the base station includes a plurality of pairs of diversity antennas. The energy from the first antenna of each pair is subjected to a delay while the energy from the second antenna of each pair is not subjected to a delay. The added delay is greater than the chip time of the rake fingers. The signals from each pair of antennas is combined and converted to digital form. The energy from all the antennas is then routed to the rake fingers, with the energy from each antenna being routed to one of the rake fingers. The energy from the rake fingers is then combined into a single data stream. In an alternative approach, the base station includes a plurality of diversity antennas. The energy from each of the diversity antennas is subjected to a different amount of delay. The delay difference must again be greater than the chip time of the rake fingers. The energy from the antennas is combined, converted to digital format, and routed to each of a plurality of rake fingers, with the energy from each antenna being routed to the rake finger. The energy from the rake fingers is then combined into a single output data stream.

Granted: 2003-06-03
Abstract: An apparatus for reducing vibration has a mount for attaching to a vibrating body, such as the frame of an aircraft.  A plate is spaced from the mount with a mass there between.  A first elastomeric ring is compressed between the mass and the mount, and a second elastomeric ring is compressed between the mass and the plate.  The rings act as a spring having a stiffness that defines a resonant frequency at which the mass oscillates.  Vibration in the body is reduced by the mass movement absorbing vibrational energy and the energy absorption is maximized when the mass resonates at the vibration frequency.  A controller senses body vibration and operates a mechanism that alters the spacing between the mount and the plate thereby adjusting the spring stiffness.  The stiffness of the spring is changed until the resonant frequency of the mass is tuned to the vibration frequency of the body.

Title: Arc fault detector with circuit interrupter and early arc fault detection
Inventor: NEIGER BENJAMIN B
IPC: H02H3/33
Filed: 1998-12-16
Granted: 2011-10-04
Abstract: An arc fault detector comprised as a stand alone unit and in combination with a ground fault circuit interrupter (GFCI) functions to provide protection from potentially dangerous arc fault conditions. When combined with a GFCI, the combination arc fault/ground fault circuit interrupter (AFCI/GFCI) provides protection from both arc fault and ground fault conditions. A single transformer is used to detect faults between neutral and ground and arc faults. An impedance splits the current flow into two portions so as to generate differential current proportional to the current flowing through the conductors. An early arcing detector periodically tests the AC line for high impedance between the device and a main breaker panel. The AFCI/GFCI device detects both AC line frequencies and high frequencies associated with arcing. Both average and instantaneous values of both AC line frequency and high frequency arcing signals are processed to generate an arc fault signal. The device allows the arc detector to differentiate between destructive high level arcing and low level arcing such as generated by typical household appliances and equipment. This serves to decrease the occurrence of false tripping. The device also includes a timer circuit, which permits the user to temporarily disable the arc detector, and includes communication means to permit the device to communicate the occurrence and location of the arc fault to a centralized monitoring station.
