Title: Jointed rockshaft with angularly adjustable segments
Inventor: SAHR ANDREW DALE
IPC: A01B63/26
Filed: 2005-09-14
Abstract: A flexible rockshaft includes joint structure (40, 140) facilitating the adjustment of the rotational angle of rockshaft segments (20a, 20b, 20c) relative to each other. A link (42, 142) inserted between a rockshaft segment (20a, 20b, 20c) and the joint structure (40, 140) rotates on the same or a parallel pivot (56, 156) as adjacent rockshaft segment (20a, 20b, 20c), and an adjustable length connecting mechanism (72, 172) on the link provides angular adjustment. In one embodiment, shims (102, 104) supported on the link (42, 142) are selectively clamped between a threaded stop and an internally threaded link. The number of shims (102, 104) may be easily varied to change the angular position of one rockshaft segment (20a, 20b, 20c) relative to the adjacent segment (20a, 20b, 20c). In another embodiment, a simpler threaded member (173) with positioning nuts (182, 184, 186) is located on the additional link (142) and provides inexpensive angular adjustability.

Title: Voice-scrambling-signal creation method and apparatus, and computer-readable storage medium therefor
Inventor: MIKI AKIRA
IPC: G10K11/175
Filed: 2007-09-06
Abstract: Original voice uttered in a first space is acquired via a microphone and a series of digital waveform data of the acquired original voice are obtained.  The waveform data are sequentially segmented into plural frames and the waveform data of the individual frames are written into a memory. In parallel with writing, into the memory, of the waveform data, individual ones of the frames already written in the memory are sequentially or randomly selected and read out in a direction opposite to a direction the waveform data of the frame have been written so that a reverse-reproduced voice signal is generated. As the original voice is transmitted, as a leaked voice from the first space to a second space near the first space, a scrambling voice based on the reverse-reproduced voice signal is spatially mixed with the leaked voice in the second space.

Abstract: When an optical network terminal (ONT) is rebooted, for example, after being upgraded, the ONT may be not be ranged and provisioned for some time. This may disrupt services, such as video services provided to a customer. As such, a method and corresponding apparatus of ensuring continuous receipt of video services based on certain conditions in a passive optical network (PON) are provided. The method may include detecting at a PON element a condition indicating a change of states in receipt of video services, starting a timing mechanism having a default value stored in the PON element, and enabling receipt of video services at the PON element for an amount of time defined by the default value. Receipt of video services may be enabled by: i) maintaining video services at a second PON element and sending the video services to the PON element, or ii) maintaining a configuration for video services previously provisioned and re--provisioning the PON element with the maintained configuration. In these ways, disruption to video services is reduced.
