Title: Method and apparatus for acquiring satellite positioning system signals
Inventor: KRASNER NORMAN F
IPC: G01S19/03
Filed: 1999-07-15
Granted: 2006-08-17
Abstract: A method and an apparatus which acquire satellite positioning system (SPS) signals in an SPS receiver. Information on time of day, approximate receiver location, and satellite positions are used to reduce the time to search and acquire signals from one or more SPS satellites. In an example of a method of the invention, a first pseudorange to a first SPS satellite is determined, and an approximate location of the SPS receiver is determined. An estimated pseudorange for a second pseudorange to a second SPS satellite is determined from the approximate location and a satellite position of the second SPS satellite. The SPS receiver then searches for SPS signals from the second SPS satellite in a range determined by the estimated pseudorange. Typically, this method reduces the search time to initially acquire SPS signals from the second SPS satellite, and the estimated pseudorange is not based on a previously determined pseudorange for said second SPS satellite. In a particular example of the invention, the approximate location is determined from a cell based information source which correlates an identification of each of various wireless cell sites with an approximate location for objects within a cell of a wireless cell based communication system, such as a cellular (or cell based) telephone system. In other examples of the invention, relatively precise time of day information may be used with information indicating satellite positions and information indicating the approximate location to determine an estimated pseudorange for a first SPS satellite to be acquired.

Title: Apparatus for selective distribution of messages over a communications network
Inventor: KAUFFMAN MARC
IPC: H04N7/16
Filed: 1991-06-05
Granted: 1996-09-03
Abstract: Specific text and/or graphic messages for individual subscribers or groups of subscribers are distributed on a communications network such as a cable television system.  An addressable controller communicates with a plurality of subscriber terminals served by the network.  Each subscriber terminal is assigned to a primary message group and may be assigned to one or more message subgroups. Messages are input to the addressable controller for subsequent transmission to a subscriber terminal for display.  The messages are tagged with distribution data defining at least one primary message group or message subgroup to receive the message.  The tagged text messages are transmitted over the network together with signals from network service providers.  Global messages can be sent by leaving the distribution data field blank, or filling it with a special code such as a string of zeros.  Wild card tags are also permitted.  A subscriber terminal for receiving the messages has a first path for processing a service signal received from the network and a second path for processing a message signal received from the network.  The distribution data is retrieved from a received message and used to determine if the message is targeted to the subscriber terminal.  If so, the message is processed for display.  The message can be displayed alone or overlaid on a video program signal being viewed.

Title: Motor control apparatus and method
Inventor: MINNICH THOMAS
IPC: H02P6/06
Filed: 1991-08-02
Granted: 1996-06-18
Abstract: An apparatus and method for controlling brushless DC motors are provided.  Velocity loop control is performed digitally to produce current commands at a high frequency loop closure interval.  Commutation of field coil current is controlled in response  to  current  commutation  pattern  control  signals produced in response to measured relative position of the motor rotor and motor stator and a velocity average over a number of loop closure intervals.  Switch control signals to control transistor switches providing current from a DC power source to the motor terminals are produced in response to the current commands, measured motor current and the commutation pattern control signals.  The velocity loop control implements a selected transfer function relating velocity, the motor torque constant, and the moment of inertia of the motor and associated load.   Facilities are provided for periodically adjusting velocity loop transfer function gain factors and the effective moment of inertia in response to input signals. Additionally, current loop amplification gain factors and time constants are made selectable by input signals.

Title: Signal lamps visible to driver
Inventor: JONES ISIAH
IPC: B60Q1/26
Filed: 1992-02-26
Granted: 1996-07-30
Abstract: A system of signal lamps for an auto or truck places the lamps where they are visible to the driver of the vehicle, as well as to the drivers of other vehicles. The lamps act as run-ning lights and turn signal lights. The system comprises four omnidirectional, surface-mounted signal lamps. These are mounted in two pairs: an amber front pair and a red rear pair. The front pair is located on that surface of the vehicle which is the front-most upper surface of the vehicle where they are within the view of the driver. These front lamps alert the driver to the lamp condition directly, and also warn other motorists. The rear pair is side-mounted, in places where the driver can see each rear lamp in one of the side-view mirrors. These locations make the lamps highly visible to the driver, because they are visible in regions where the driver habitually looks, and because they are angularly close to the normal view straight ahead. They are more visible to other drivers. as well . both because they are omnidirectional and because they are located higher than ordinary lamps, and so are less likely to be hidden when vehicles are very close to one another. The system may be installed as original equipment or added onto an existing vehicle as accessories.

Title: A flow tube drive circuit having a bursty output for use in a coriolis meter
Inventor: KALOTAY PAUL
IPC: G01N9/00
Filed: 1990-11-29
Granted: 1996-06-25
Abstract: A drive circuit for providing burst, rather than continuously alternating amounts,  of energy for use in driving a flow tube (conduit) in a Coriolis meter  and  methods  for  use  in  such  a  circuit. Specifically,    the   drive   circuit   provides   a pre-defined burst of energy to a drive coil affixed to a flow conduit at an appropriate point during a cycle of the oscillatory motion of the conduit in order  to  maintain  the  peak  amplitude  of  the oscillatory motion substantially within a prescribed range.  This burst can be applied at a pre-defined point,  illustratively the peak, in each cycle of the oscillatory  motion  with  no  energy  being  applied during that cycle other than when the pulse occurs in order  to  reduce  the  amount  of  electrical  energy applied to the drive coil.  Alternatively, to further reduce this  energy,   a burst need not be  applied during every  such cycle but rather only  at those pre-defined points,  e.g.  the peaks,  within those cycles where the velocity of the flow conduit is less than a pre-defined limit value.
