  • Patent number: 8970204
    Abstract: A wireless phasing voltmeter determines the phase difference between the voltage carried by a reference electrical conductor and a field conductor. The voltage signal from the reference conductor is detected by a first unit and compared to a precision 60 Hz wave form generated from a first 1 pps GPS signal. The phase difference between the wave form and the reference conductor, represented by nine data bits, is used to modulate a radio frequency carrier wave and transmitted via simplex transmission to a second unit near an electrical conductor in the field. The second unit receives the modulated carrier wave, decodes the phase angle difference and compares it to a second phase angle difference between the voltage on the field conductor and a second precision 60 Hz wave form generated from a second 1 pps GPS signal. The difference between the two phase differences determines the phase of the field conductor.

  • Patent number: 8750473
    Abstract: Techniques have been developed for transmitting and receiving information conveyed through the air from one portable device to another as a generally unperceivable coding within an otherwise recognizable acoustic signal. For example, in some embodiments in accordance with the present invention(s), information is acoustically communicated from a first handheld device toward a second by encoding the information in a signal that, when converted into acoustic energy at an acoustic transducer of the first handheld device, is characterized in that the acoustic energy is discernable to a human ear yet the encoding of the information therein is generally not perceivable by the human. The acoustic energy is transmitted from the acoustic transducer of the first handheld device toward the second handheld device across an air gap that constitutes a substantially entirety of the distance between the devices.

  • Patent number: 8380420
    Abstract: Precise operation of an accelerator operating member (7) is more difficult to perform in a reversing operation of a vehicle (1) as compared with an advancing operation. Therefore, behavior of the vehicle (1) is not smooth and thus tends to be unnatural. In the reversing operation of the vehicle (1), driving force output from an internal combustion engine (2) is limited in accordance with vehicle acceleration (D). At this time, it is possible to regulate the driving force of the vehicle (1) in conformity to the actual operation of the accelerator operating member (7) by the driver. In addition, limitation of the driving force is not executed in the advancing operation of the vehicle (1). At this time, the vehicle (1) can be driven in a state in which the driving force is comparatively small. Therefore, it is possible to prevent the behavior of the vehicle (1) from being unnatural.

  • Patent number: 7650282
    Abstract: An approach to scoring acoustically-based events, such as hypothesized instances of keywords, in a speech processing system make use of scores of individual components of the event. Data characterizing an instance of an event are first accepted. This data includes a score for the event. The event is associated with a number of component events from a set of component events, such as a set of phonemes. Probability models are also accepted for component scores associated with each of the set of component events in each of two of more possible classes of the event, such as a class of true occurrences of the event and a class of false detections of the event. The event is then scored. This scoring includes computing a probability of one of the two or more possible classes for the event using the accepted probability models.

  • Patent number: 7433452
    Abstract: A method of using a telecommunications network cashless transaction service is provided, in which a user accesses the service using a network access instrument, such as a mobile phone which produces a signal. The signal is forwarded to an interface device of the network, which extracts service and user identity data therefrom, and passes the data to a processing unit for the service of the network. The service processing unit processes the data, instructs the interface device to forward the access instrument signal to an input output device of the network, and instructs the input output device to request transaction details from the user. The details are sent to the input output device, which passes them to the service processing unit which processes the details and decides whether or not the transaction can proceed, causes output of a signal conveying acceptance or rejection of the transaction to the user, and, if the transaction can proceed, arranges for the transaction to be carried out.
