Granted: 2001-04-17
Abstract: In a system for simulcasting a digitally modulated signal and an analog FM signal over the same FM frequency band, the composite signal is received and applied to a conventional FM receiver, and a digital receiver in accordance with the invention. An extended Kalman filter is employed in the digital receiver to estimate the analog FM signal based on a version of the recovered FM signal from the FM receiver, and a discrete version of the composite signal whose spectrum has been translated and is at an intermediate carrier frequency. The estimated FM signal, which is in a discrete form, is subtracted from the discrete version of the composite signal. The resulting signal, which is an estimated version of the digitally modulated signal, is demodulated to recover the digital data as transmitted.

Title: Video coder providing implicit or explicit prediction for image coding and intra coding of video
Inventor: SCHMIDT ROBERT LEWIS
IPC: H04N19/593
Filed: 1998-01-20
Granted: 2002-10-01
Abstract: A  predictive  video  coder  performs  gradient prediction based on previous blocks of image data. For  a  new  block  of  image  data,  the  prediction determines  a  horizontal  gradient  and  a  vertical gradient from a block diagonally above the new block (vertically  above  a  previous  horizontally  adjacent block).    Based  on  these  gradients,  the  encoder predicts image information based on image information of either the horizontally adjacent block or a block vertically adjacent to the new block.   The encoder determines a residual that is transmitted in an output bitstream.     The  decoder  performs  the  identical gradient  prediction  and  predicts  image  information without need for overhead information.   The decoder computes the actual information based on the predicted information and the residual from the bitstream.

Title: Gasoline desulfurization process
Inventor: HICKEY THOMAS P
IPC: C10G45/00
Filed: 1996-07-12
Granted: 2007-05-29
Abstract: A catalytic cracked naphtha is desulfurized with minimum loss of olefins and octane. The naphtha is fed to a first distillation column reactor (10) which acts as a depentanizer or dehexanizer with the lighter material containing most of the olefins and mercaptans being boiled up into a first distillation reaction zone (11) where the mercaptans are reacted with diolefins to form sulfides which are removed in the bottoms along with any higher boiling sulfur compounds. The bottoms are subjected to hydrodesulfurization in a second distillation column reactor (20) where the sulfur compounds are converted to H2S and removed. The lighter fraction containing most of the olefins is thus not subjected to the more harsh hydrogenation conditions of the second reactor (20).

Filed: 1996-12-11
Granted: 2000-06-13
Abstract: The invention manifests a secure, on-demand meet-me conferencing service embodied within a telephone network having an advanced intelligent network (AIN) infrastructure. Centralized control from a service control point of provisioned conferencing bridges located in network switches is effected in the AIN telephone network, thereby overcoming the resource efficiency limitations and corresponding costs of the prior art systems. In addition, it enables the local exchange carrier (LEC) to offer of a new type of conferencing service at a lower cost where prior reservation of conferencing facilities is no longer necessary and which possesses other advantages with respect to ease of use, ease of administration, availability and security.  Users of the service first subscribe to it, and then utilize paired primary and secondary authorization codes to access a conference.

Filed: 1998-10-06
Granted: 2003-07-01
Abstract: In a digital cellular communications network, calls to and from a fax machine or other data equipment coupled to a digital phone require special encoding circuitry. Calls to and from a fax machine or other data device using amplitude and/or phase modulated tones can be handled more efficiently by monitoring such incoming calls for the presence of audio control tones. Upon the detection of such tones, appropriate encoding circuitry is automatically switched in to properly encode/decode data tones so as to permit the automatic transmission of data over a wireless cellular network using CDMA, TDMA or other digital protocols.

IPC: G01R19/155
Filed: 1999-01-20
Granted: 2002-03-26
Abstract: An automatic power turn-on circuit for a battery-powered measurement instrument. Instrument power is normally off, and when the instrument is connected to a voltage to be measured, the voltage that is sensed activates an electronic switch that in turn connects an internal battery to the processing and display circuits of the instrument. The voltage sense circuitry includes circuits for sensing either a positive or a negative voltage, and biasing a driver transistor into conduction. The driver transistor in turn activates the switch to connect the battery voltage to a power supply output node. An RC  network holds the switch in the "on" position for a short period of time after the voltage to be measured is removed from the inputs of the instrument.
