Passing-type-meshing negative-deflection strain wave gearing

A strain wave gearing is a negative deflection strain wave gearing. The tooth profile shape for the internally toothed gear is defined by using a convex, basic tooth profile curve, which is a curve portion from an inflection point (a) to a bottom-part point (b) of a moving locus (mc) of an externally toothed gear with regard to an internally toothed gear obtained by a rack meshing approximation. ... Harmonic Inc

Planetary gear reducer

A planetary gear reducer has a planetary carrier supported by an input-side main bearing and an output-side main bearing. An angular contact ball bearing or a deep groove ball bearing which requires less installation space and is inexpensive is used for the input-side main bearing. ... Harmonic Inc

Strain wave gearing

A flat strain wave gearing device equipped with: a first internal gear and a second internal gear; a flexible tubular external gear; and an elliptically shaped wave generator. In the direction of a central axis, the center of support of the external teeth by the wave generator is offset, by an offset amount of Δ along the direction of the central axis, with respect to the tooth-width center of the external teeth of the external gear. ... Harmonic Inc

Browsing and viewing video assets using tv set-top box

Roughly described, a system and method for delivering video content to a user's client device in a video-on-demand (vod) system, which includes providing a collection of video segments, the segments having a predefined default sequence; establishing a streaming video session according to a session-oriented protocol; transmitting toward the client device a script executable by the client device, the script operable to transmit navigational codes toward the head-end equipment in response to and indicating user selection among navigational choices; beginning transmission of the video segments in the collection toward the client device in accordance with the default sequence of segments; and in response to receipt of one of the navigational codes, and without tearing down the streaming video session, altering the transmission sequence to jump to the segment that the user selected.. . ... Harmonic Inc
