Abstract: A fiber optic connector including a ferrule surrounding an optical fiber and a hub engaging the ferrule. The hub includes a front portion having first and second opposing surfaces and first and second tapered regions extending from the first and second opposing surfaces to a front face. A housing includes an anti-rotation seat configured to engage the first and second opposing surfaces, the anti-rotation seat including parallel first and second contact lines positioned at a front of the anti-rotation seat. A spring within a chamber of the housing biases the ferrule through a bore in the front of the housing. The first tapered region of the hub engages the first contact line and the second tapered region engages the second contact line when the hub and ferrule are in a first rotational position so that the optical fiber is maintained at a known orientation with respect to the connector.

Abstract: An “Alert” tab or button is displayed on the Graphical User Interface (GUI) of a videoconference terminal when a problem is detected in the embedded system. Selecting the tab or button—e.g., with a pointing device—causes the display to switch to a diagnostic page which provides a specific indication of the problem which has occurred. In some embodiments, the diagnostic page may provide a graphical indication of the status of various sub-systems.

Abstract: An apparatus and method for detecting the presence of a valid signal includes an offset generator coupled to a pair of data slicers and an XOR gate. The offset generator is configured to both add and subtract a predetermined voltage to an input voltage in its two outputs. The two outputs of the offset generator are both compared to a predetermined value in a pair of data slicers. If the outputs of the data slicers are the same (i.e., either both offset signals are positive or both are negative), then a valid signal is indicated.

Abstract: An exercise device having a hollow housing that can be fixed to a horizontally disposed support surface by a first external clamp. Extending from the housing is a handle with a first shaft that extends into the housing. Within the housing on the first shaft is a disk fixed to the shaft that rotates with the shaft. As a user rotates the handle its shaft and disk rotate in unison. A resistive force control handle also extends from the housing has its own second shaft extending within the housing. This second shaft mounts a second member consisting of two disk engaging rollers whose resistance to rotation can be adjusted. As the rollers resistance to rotation is increased against the engage disk's surface more force is needed to move the external handle on the disk's shaft. One roller engages the top of the disk while another engages the bottom of the disk. Two pairs of arms are joined at one end to a movable shaft while the other end has a roller at each one of the pairs of arms.
