Patent CA-2437177-A1 (CA)
Inventor: KIANI SEPEHR
IPC: G02B6/38
Filed: 2002-01-30
Abstract: The invention is directed to techniques for controlling access to an optical interface using film having windowed sections and non-windowed sections. The windowed and non-windowed sections are selectively positioned over an optica l interface location that holds the optical interface in order to protect the optical interface. Preferably, such positioning occurs in an automated manne r such that a technician need not perform an extensive cleaning step each time fiber optic equipment requires handling, e.g., each time a fiber optic connector of a fiber optic component is unplugged and re-plugged. In one arrangement, an optical connector housing holds the optical interface in an optical interface location of the optical connector housing, and a film positioning assembly selectively positions windowed and non-windowed section s of film over the optical interface location in order to selectively expose a nd protect the optical interface.

Inventor: KYI SAN KYI
IPC: B29C49/48
Filed: 2003-12-30
Abstract: A mold half carrier has first and second air flow compensating surface areas. The second air flow compensating surface area encloses the first air flow compensating surface area. The first air flow compensating surface area provides pressure compensation for formation of smaller containers. Both air flow compensating surface areas are utilized for formation of larger containers. A shut off valve controls air flow through a passage in the mold carrier extending between the first and second air flow compensating surface areas. The second air flow compensating surface area has an exhaust passage for bleeding unwanted pressurized air therefrom when the shut off valve is closed. The compensating surface areas are separated from each other by a common continuous groove and an O-ring mounted in the groove. The groove has an arcuate main portion for receiving the O-ring and an auxiliary portion into which a portion of the O-ring may collapse.

Abstract: The present invention provides a strap tab cap (40) for connecting a strap t ab (64) to a knee brace frame (53) wherein the strap tab cap has a very low profile and can rotate relative to the knee brace frame within a limited range. The low profile of the strap tab cap (40) reduces the possibility tha t the strap tab cap will catch on a foreign object during physical activity. T he limited rotation of the strap tab cap (40) allows a strap (66) to be adjuste d for improved fitting on a user's leg. The strap tab cap (40) is attached to the knee brace frame (53) with a rivet (54) that extends through a central hole (44) in the strap tab cap. Two posts (50, 52) extend downward from the strap tab cap into slots (58, 60) in the knee brace frame for limiting the rotation of the strap tab cap. One or more strap tabs (64) are maintained within channels (46, 48) formed on the bottom side of the strap tab cap.</SD OAB>

Abstract: Combined plain old telephone system (POTS) and digital subscriber loop (DSL) line card capable of suppressing low frequency transmission. The line card (400) includes following elements. A DSL receive path (403) receives DSL data from a loop (61). A POTS receive path (402) receives POTS data from the loop.  A combined POTS and DSL transmit path (401) transmits POTS and DSL data to the loop. An impedance generator (80) is coupled between the POTS receive path and the combined POTS and DSL transmit path for synthesizing impedance for signals in the combined transmission path. A low frequency detector (70) selectively applies a high pass filter (41) to an output of the impedance generator for filtering the low frequency transients. Further, a clipped signal detector (30) and variable pole high pass filter (13) are provided in the POTS receive path. The clipped signal detector triggers a switch that discharges stored transient energy in the receive path. The variable pole high pass filter is modified during ringing and hook switch activity by a controller (409) in order to attenuate transient signals.
