Abstract: A method of displaying a relative position of a current page (168) of a book displayed using an electronic book (118) having a book-shaped housing (100) includes displaying the current page (168) on a first portion of a display device (130) incorporated in the book-shaped housing (100). A graphical representation (178, 188) of the relative position of the current page (168) within the book is displayed on a second portion of the display device (130), the second portion being peripheral to the first portion. The graphical representation (178, 188) can include an image of a plurality of page edges located proximate to an edge of the first portion, the plurality of page edges aligned generally parallel to the edge. The edge can be either a side edge, a top edge, or a bottom edge of the first portion.

Abstract: A noise suppression system (109) implemented in communication system (700) provides an improved update decision during instances of sudden increase in background noise level. The noise suppression system (109), inter alia, generates an update by continually monitoring the deviation of spectral energy and forcing an update based on a predetermined threshold criterion. The spectral energy deviation is determined by utilizing an element which has the past values of the power spectral components exponentially weighted. The exponential weighting is a function of the current input energy, which means the higher the input signal energy, the longer the exponential window. Conversely, the lower the signal energy, the shorter the exponential window. The noise suppression system (109) also inhibits a forced update during periods of continuous, non-stationary input signals (such as "music-on-hold").

Abstract translation: 在通信系统（700）中实现的噪声抑制系统（109）在背景噪声水平突然增加的情况下提供改进的更新决定。 噪声抑制系统（109）尤其通过连续地监视频谱能量的偏差并基于预定的阈值准则来迫使更新来产生更新。 通过利用具有指数加权的功率谱分量的过去值的元素来确定光谱能量偏差。 指数加权是当前输入能量的函数，这意味着输入信号能量越高，指数窗口越长。 相反，信号能量越低，指数窗口越短。 噪声抑制系统（109）还在连续的，不稳定的输入信号（诸如“保持音乐”）期间抑制强制更新。

Abstract: A two-way data device (200) in which, when a new message is received that comprises identical data and an identical tracking identifier as an existing message, the new message is considered a duplicate of the existing message. Duplicate messages are first checked to determine if the data portion of the message contains errors. When the data portion of the new/duplicate message fails the error check, the data portion of the old message is kept and the data portion of the new message is deleted. Alternatively, when the data portion of the new/duplicate message passes the error check, and a signature and response flag within the new and existing messages meet certain criteria, the data portion of the old message is replaced with the data portion of the new/duplicate message. As a result, message memory is utilized more efficiently as duplicate data is not repetitively stored therein.

Abstract: A speech signal is sampled (110) to form a sequence of speech data and segmented (120) into segments. The envelope of each segment is detected (210) to form an envelope segment. Each datum of the segment is divided (220) by each datum of the envelope segment to form a de-envelope segment which is transformed (230) into spectral components. Dominant frequencies are determined (310) for the spectral components with greatest magnitudes. Envelope coefficients are generated (320) by fitting a polynomial function to the segment. Phase parameters are generated (330) representing a phase of each of the dominant spectral components. The dominant frequencies, the envelope coefficients and the phase parameters are generated (340) as compressed speech data for each voiced segment. For each unvoiced segment, a carrier frequency, an amplitude and at least one sideband frequency of an amplitude modulation component are generated (430) as the compressed speech data.
