Abstract: Methods and systems for creating a comfortable, user-friendly environment that allows a hearing impaired user to identify who is speaking and preferably what is being said during interactions with other individuals, e.g., at any form of meeting. In accordance with the invention, it is determined whether or not someone is speaking. If yes, then the speaker's position is identified. It is also determined whether the speaker is in the range of view for the user's display. If yes, an illuminated dot is projected above the speaker on a wearable display to show the user where the speaker is located. If no, a directional arrow is projected on the display to indicate to the user which way he should look to see the current speaker.

Abstract: A speech conversation is changed to a text transcript, which is then pre-processed and subjected to text mining to determine salient terms. Salient terms are those terms that meet a predetermined level of selectivity in a collection. The text transcript of the speech conversation is displayed by emphasizing the salient terms and minimizing non-salient terms. An interface is provided that allows a user to select a salient term, whereupon the speech conversation is played beginning at the location, in the speech file, of the selected salient term.

Abstract: The handover control method for use in a mobile communication system changes a handover method according to an overlapping zone residence time of a mobile station by ranking three handover methods for the mobile station including a gateway handover method, a base station controller path extension handover method, and a radio link path extension handover method in association with how long the overlapping zone residence time of the mobile station is, and by selecting one handover method that corresponds to the overlapping zone residence time of the mobile station. When either the gateway handover method or the base station controller path extension handover method is selected for use, the handover method selects a handover path of which load on the system is minimum among the handover paths that can be employed by the selected handover method.

Abstract: A device (102) that can perform voice recognition operates with a removable media or memory (104) that is used to store information records (126). To save memory space in the removable media, voice recognition tags (118), used to perform voice recognition, are not stored in the removable media, but are stored in the device. Since the media is removable, the device must check to make sure the records stored in the media are usable with the voice recognition tags. This is accomplished by generating a key (306) whenever a new voice recognition tag is trained (304). The key is stored in the device, or in the media, or both. Upon initialization of the device, (202), the device searches (206) the media for records and checks (210) to see if the key corresponding to the record matches any keys in the device. When a match is found the record is associated (214) with the corresponding voice recognition tag. Voice recognition tags with no corresponding records are deleted or ignored.

Abstract: Voice-controlled apparatus is provided which minimises the risk of activating more than one such apparatus at a time where multiple voice-controlled apparatus exist in close proximity. To start voice control of the apparatus, a user needs to be looking at the apparatus when speaking. Preferably, after the user stops looking at the apparatus, continuing voice control can only be effected whilst the user continues speaking without breaks longer than a predetermined duration. Detection of whether the user is looking at the apparatus can be effected in a number of ways including by the use of camera systems, by a head-mounted directional transmitter, and by detecting the location and direction of facing of the user.

Abstract: A calibration for a tracking error signal offset in a tracking servo system of an optical disk drive is presented. In some embodiments, the tracking error signal offset is adjusted for best servo function by, for example, adjusting the center of a tracking error signal when the tracking servo system is open to zero. In some embodiments, the tracking error signal offset is adjusted for best read function by, for example, adjusting the tracking error signal offset until the data jitter is minimized. Data jitter can be determined by reading data from the optical media and measuring the data error rate.

Abstract: The present invention provides an optical disk device which optimizes recording power level used when recording data. A controller records test data in a test region of an optical disk and evaluates reproduced signal quality of the test data, so as to determine an optimum recording power level Po (OPC). Subsequently, the controller uses reflected light intensity level B obtained when recording data to make adjustments to the optimum recording power level Po, thereby obtaining recording power level P. The recording power level P is adjusted such that Bm/Pn=constant, where m and n are positive rational numbers satisfying m<n. When m=1, the value of n is greater than or equal to 1.5 and no larger than 10.

Abstract: A radio frequency ripple zero crossing signal calibration method for an optical disk reader undergoing a track following to track seeking transition is disclosed. The method utilizes sampling to obtain radio frequency ripple peak level during a track seeking operation and radio frequency ripple DC level during a track following operation and using their differences as a calibrated value. Through the calibrated value, the radio frequency ripple zero crossing slice level is modified so that a correct radio frequency ripple zero crossing signal is obtained during a track following to track seeking transition. In a track following to seeking transition, this arrangement prevents distortion of the radio frequency ripple signal and corresponding drift in the radio frequency zero crossing signal that may lead to errors in computing moving speed and counting tracks of the pickup head. Hence, search capacity of the optical disk reader is improved and the pickup head is better controlled.

Abstract: A communication system includes a base station and a plurality of remote stations wirelessly communicating with the base station. The base station determines a respective RF quality for each remote station. In response to a request for RF resources from a given remote station, the base station determines whether admission of the given remote station would exceed an RF power budget threshold. If the RF power budget threshold would not be exceeded, the RF quality is compared to a first quality threshold to determine whether to allocate the requested RF resource to the given remote station. Otherwise, the RF quality is compared to a second quality threshold more stringent than the first quality threshold to determine whether to allocate the RF resource to the given remote station. The base station may further determine whether to allocate requested RF resources on the basis of a priority of the requested resources.
