    Abstract: A receiving section of an infrared receiver includes an error detecting section that detects, through an integrating circuit, a direct-current component of a 1-bit data sequence that is supplied in a form of a PDM signal. The direct-current component thus detected is compared with a reference voltage by the comparing circuit to determine whether the direct-current component is greater or smaller than the reference voltage, and a signal is outputted on the basis of a result of the comparison. When the direct-current component is decreased, it is determined that a bit error rate is greater. At this time, an output of sound from the infrared receiver is caused to become OFF.

    Abstract: A method and apparatus for computing soft decision input metrics to a turbo decoder includes circuits associated with eight-ary phase shift keyed (8PSK) modulation and sixteen-ary quadrature amplitude modulation (16QAM). In both implementations log-likelihood ratio (LLR) metrics on code symbols are estimated as products of various constant values and various combinations of the in-phase and quadrature components of a demodulated soft decision. In the implementation associated with the 16QAM modulation scheme, an estimate of the carrier-signal-to-interference (C/I) ratio is also used to estimate some of the LLR metrics. Estimates of the LLR metrics may also be obtained in association with generalized square QAM and M-ary PSK modulation schemes including, e.g., 64QAM, 256QAM, and 16PSK.

  • Publication number: 20070127606
    Abstract: A synchronization method and a detection method capable of resisting noise and waveform distortion in a communication system and a correlator thereof are proposed. In the method, over-sampling is performed to a preamble and a synchronization word in an access code, and a different weighting value is assigned to each sampled point based on its reliability. A correlator is then used to calculate a correlation value. The time instant when this correlation value exceeds an initial threshold is used as the time instant to activate a timer. The time instant when the calculated correlation value is maximal within the time interval from the timer is activated to a predetermined observation time interval is used as the optimum synchronized timing instant to accomplish bit synchronization and frame synchronization at the same time. Moreover, the optimum synchronized timing instant can be used as a reference instant for bit detection to enhance the capability of resisting noise and waveform distortion.

    Abstract: The invention relates to improved methods and systems for computationally efficient optimization of radiation dose delivery. The optimization involves determining an improved form of objective function to be used for mapping radiotherapy beams to a patient body volume having at least one target volume and at least one non-target volume. The objective function has a first term related to the at least one target volume and a second term related to the at least one non-target volume. The optimization further involves determining a minimum of the objective function, whereby beams mapped so as to pass through the at least one non-target volume are limited such that the second term is zero only if the weights of beamlets passing through the at least one non-target volume are zero. This limit helps to avoid the occurrence of negative beam weights, thereby facilitating computationally efficient determination of the minimum of the objective function using matrix inversion.

  • Publication number: 20070127632
    Abstract: Methods and apparatus for controlling and retrieving messages from multiple voice mail systems used by a single individual are described. A voice messaging retrieval and forwarding (VMRAF) system checks a subscriber's voice message systems for messages, retrieves the messages and forwards them to the subscriber as attachments to E-mail files. E-mail replay messages are used to control deleting of the messages from the original systems. Prompt messages played to callers by different voice messaging systems before they leave a message can be updated automatically. This is done by indicating to the VMRAF system when one or more prompt messages are to be updated and which messages, from a set of prerecorded messages, are to be loaded into the voice message systems to replace the existing prompt messages. Accordingly, the VMRAF system facilities message retrieval and the updating of prompt messages, e.g., on a preselected schedule or at preselected times.

  • Publication number: 20070127633
    Abstract: A method for operating a communications link between two telecommunications device requires that speech information be transmitted in a speech channel and data signals are transmitted in a data channel that is separate from the speech channel. This provides a particularly user-friendly, convenient method for operating a telecommunications link. To achieve this, display control commands are transmitted in the data channel as data signals, the display control commands triggering a display on a screen of the telecommunications device that receives the display control commands.

  • Publication number: 20070127634
    Abstract: This call recording device includes: a transmission signal processing unit that superimposes a probe signal on a transmitted voice signal; a reception signal processing unit that monitors a received voice signal and that detects the probe signal included in the received voice signal, and decides the onhook/offhook condition of the telephone in accordance with the probe signal thus detected; and a data transmission processing unit that executes recording process when the offhook condition is identified. The reception signal processing unit includes: a PSK demodulator that demodulates the received voice signal; a correlator that calculates a correlation value of the demodulated signal and a replica code pattern corresponding to the probe signal; and a decision processing unit that decides that the telephone is in the offhook condition if the integrated value of the correlation value is at least a prescribed threshold value.

  • Publication number: 20070127635
    Abstract: A system and method of call-routing and caller-screening that employs voice recognition to automatically recognize a caller's voice and then screen a caller, if appropriate; all without forcing the caller to identity himself/herself, which may be perceived as rude or offensive by some callers. Instead, a synthesized voice automatically asks the caller to identify who the caller wishes to speak with. Caller's response to this query is used to identify the callee as well as to optionally identify the caller. Thus, the screening of the caller takes place in a manner that the caller perceives as a more natural way of telephone communication. Caller's speech is used to generate digital voice samples therefrom and the caller's voice samples are directly compared with other voice samples stored in a database without converting the voice samples into digital text files.

  • Publication number: 20070127636
    Abstract: Methods and systems relating to a communication in an Advanced Intelligent Network from a caller to a subscriber's directory number where the communication has been terminated to a voice mail system (VMS) instead having been terminated to the subscriber's directory number. The methods and systems transfer the communication from the VMS so the VMS is no longer involved in the communication. A message indicating a release of the communication by the VMS is generated. The message also indicates an action to be taken regarding the communication such as a transfer to a different number. The action and related information may be provided in a remote operations parameter of a GR-1129 message. In response, directions are provided to carry-out the action. As a result, the communication is released from the VMS, and is acted upon without further involvement of the VMS.

  • Publication number: 20070127638
    Abstract: Voicemail is received at a voicemail server and converted to an audio file format; it is then sent or streamed over a wide area network to a voice to text transcription system comprising a network of computers. One of the networked computers plays back the voice message to an operator and the operator intelligently transcribes the actual message from the original voice message by entering the corresponding text message (actually a succinct version of the original voice message, not a verbose word-for-word conversion) into the computer to generate a transcribed text message. The transcribed text message is then sent to the wireless information device from the computer. Because human operators are used instead of machine transcription, voicemails are converted accurately, intelligently, appropriately and succinctly into text messages (SMS/MMS).
