Abstract: A modular wheelchair assembly is adapted to be reconfigured between a fixed angle of tilt, a dynamically adjustable tilt-in-space configuration with the tilt axis being near the user's knees and a dynamically adjustable tilt-in-space configuration with the tilt axis being near the user's center of gravity. The reconfiguration is achieved by modifying a limited number of selectively removable components of the support assembly or the pivot assembly of the wheelchair.

Abstract: Described are techniques for clustering a data set of objects. Divide phase processing is performed to partition the data set into two or more partitions forming a hierarchy of the objects. Merge phase processing may be performing using the hierarchy to determine one or more disjoint clusters of objects of the data set. Optional preprocessing may be performed to determine weights for one or more features of an object.

Abstract: High compression rate codecs in gateways servicing Voice-over-Internet Protocol (VoIP) and Voice Band Data (VBD) calls distort modem/fax Answer Back Tones (e.g., 2100 Hz), which may lead to signal distortion and call hang-ups. To prevent such occurrences, a method or corresponding apparatus forces originating and terminating gateways to stay in a low complexity non-voice compression codec (e.g., ITU G.711) after prenegotiating a high complexity, voice compression codec (e.g., G.729 or G.726) during a short beginning period of a voice call. The low complexity codec avoids distorted answer back tone leakage associated with previous solutions that use a notch filter to block the leakage, thereby significantly improving the success rate of a VBD call by completely eliminating modem answer back tone distortion caused by high complexity codecs that use voice compression and by completely eliminating use of the notch filter.

Abstract translation: 通过互联网语音协议（VoIP）和语音频带数据（VBD）的网关中的高压缩率编解码器调用可能导致信号失真和呼叫挂断的调制解调器/传真回答音（例如，2100 Hz）。 为了防止这种情况发生，在预先谈判高复杂度的语音压缩编解码器（例如G.729或者G.711）之后，方法或相应的装置强制发起和终止网关停留在低复杂度的非语音压缩编解码器（例如，ITU G.711） G.726）在语音通话的短的开始阶段。 低复杂度编解码器避免了与使用陷波滤波器阻止泄漏的以前解决方案相关的失真回答音泄漏，从而通过完全消除由使用语音的高复杂度编解码器引起的调制解调器应答回音失真，从而显着提高了VBD呼叫的成功率 并通过完全消除陷波滤波器的使用。

Abstract: A tuning device uses a counter mode encryption cipher to encrypt counters associated with media content in order to protect the media content when it is sent to requesting device or controller. The encrypted counters are decrypted in order to consume the media content. The controller may send particular direction to the tuning device as to how the media content, encrypted counters, and other associated data are sent to the controller.
