  • System and method for providing temperature correction in a crystal oscillator
    Patent number: 7466209
    Abstract: A system and method for providing temperature compensation in a oscillator component (such as a crystal oscillator component) that includes a closely-located temperature sensing device. The crystal oscillator component in example systems and methods is exposed to a temperature profile during a calibration procedure. Temperature and frequency data are collected and applied to coefficient generating function according to a temperature compensation model to generate a set of coefficients that are used in the temperature compensation model in an application device. The generated coefficients are stored in a coefficient memory accessible to an application device during operation.

  • Electric motor system
    Patent number: 7439698
    Abstract: An electric motor system having a rotor with a plurality of permanent magnets, and a stator having a winding through which current is flowing for driving the rotor. A control unit controls the current flowing through the winding. The control unit employs a first filter and a second filter, each filter is connected to the winding and has outputs coupled to a comparator. The comparator compares the signal output of the first filter to the signal output of the second filter. The control unit controls the current flowing through the winding depending on the result of the comparison of the two filtered signals.

  • Tangential stress reduction system in a loudspeaker suspension
    Patent number: 7438155
    Abstract: A speaker system is provided, including a suspension element having an outer edge and an inner edge. The suspension element, such as a spider or surround, varies in shape along at least a portion of the suspension element to help relieve both the radial and tangential stress placed on the suspension element when it is stretched. The shape employed in the suspension element allows the suspension element to stretch more easily, creating a higher performance speaker of the same size by increasing the diaphragm excursion and voice coil movement.

  • Monolithic GPS RF front end integrated circuit
    Patent number: 7369830
    Abstract: A highly integrated GPS RF Front End which uses a single conversion stage employs an image rejection mixer stage to eliminate the need for an image reject RF bandpass filter. Also a relatively high sample rate A/D is employed which allows a timeless monolitic IF Filter to be used. The disclosure also discusses a GPS Front End topology that is easily integrated from industry standard building blocks. With the broad variation in potential receiver designs, the present invention includes some specific receiver topologies that lend themselves to a high level of integration. The specific designs presented here are comprised of industry standard building blocks and functions that have been described elsewhere in the related art.

  • Alternative communications paths for data sent over power line carrier
    Patent number: 7366773
    Abstract: Extensions to the concept of using a power line carrier to convey a data record from the secondary side of a first transformer to a receiver in a power distribution substation include receiving the data record over a secondary data path in the event that the primary path is not available. The data record received over the secondary path through a second transformer rather than the first transformer must not interfere with other data transmissions from other transmitters and needs to identify the source of the transmission. An alternative to using a secondary data path through second transformer rather than the first transformer is to provide a data bridge around an opening in the primary path. This abstract is drafted to aid those searching for relevant patents and does not represent a legal limit on the scope of claims arising from patents claiming priority to this application.

  • Location services system that reduces auto-correlation or cross-correlation in weak signals
    Patent number: 7365680
    Abstract: The present invention discloses methods, apparatuses, and systems for eliminating auto- and cross-correlation in weak signal CDMA systems, such as GPS systems. The invention uses parallel data paths that allow standard correlation of signals in parallel with verification of the lock signal to determine whether the system has locked onto the proper signal within the scanned signal window. The invention can be made with multiple CPUs, a single CPU with dual input modes, on multiple IC chips, or as a single IC chip solution for small, low cost reception, downconversion, correlation, and verification systems.

  • Inter-language translation device
    Patent number: 7359861
    Abstract: A computer system with an appropriate set of instructions to allow the computer system to serve as a translation device for use in a structured interview between an interviewer using a first language and an interviewee in a second language in order to minimize or eliminate that need for a human translator during the acquisition of routine information. Problems addressed include: determination of the appropriate language for use as the second language, the use of a single display screen through the use of a toggle function to toggle from the first language to the second language, delivery of context sensitive audio files while controlling the number of screens to be created and presented to the interviewer, and the creation of a set of discharge instructions. A preferred set of hardware and a mobile cart is discussed.

  • Apparatus and method for rapid detection of unidirectional breaks in a network ring
    Patent number: 7355965
    Abstract: Normal 802.3 Ethernet requires a tree topology. If a ring or a loop exists, then packets will be forwarded around the ring indefinitely. If the ring is broken, then there is no possibility of packets being propagated forever. This invention shows how to quickly impose a virtual break in the ring such that all nodes can communicate with each other, and how to remove the virtual break when a real failure occurs. This is accomplished by placing intelligent nodes on the ring that work together to virtually break and restore the ring. An embodiment is disclosed that handles a unidirectional break in a communication link where the unidirectional break is not sensed as an OPER DOWN state. This abstract is provided as an aid to those performing prior art searches and not a limitation on the scope of the claims.
