Filed: 1997-11-27
Abstract: A radio-frequency output signal having a specified char-acteristic is produced using a combination of a calibrated radio unit in which a calibration factor is stored and an uncalibrated modem unit. The calibration factor is input to the modem unit from the radio unit, and the modem outputs to the radio unit a signal of a nominal signal level determined in accordance with the calibration factor. An actual signal level of the signal is mesured, and a gain factor within the modem unit is adjusted until the nominal signal level and the actual signal level are sub-stantially equal. A wireless modem includes a calibrated radio unit and an uncalibrated modem unit coupled to the radio unit.  A first signal path is provided from the modem unit to the ra-dio unit, and a feedback signal path from the radio unit to the modem unit. The modem unit includes control circuitry for out-putting across the first signal path a signal that is nominally of a desired signal level, and for adjusting a nominal signal level of the signal in accordance with information received across the feedback signal path.

Inventor: HSIEH CHENG-FENG
IPC: E03F9/00
Filed: 1999-07-22
Abstract: A manually cranking/electrical pipe cleaner includes a hollow main body in which an elastic wire is wound and received. A pipe axially extends from one end of the main body. An eccentric board is disposed at front end of the pipe. An outer tube is fitted around the pipe. A front cap is screwed with the front end of the outer tube. A restricting board is disposed in the front cap and formed with a cross-like perforation having multiple semicircular interconnected peripheral walls. The elastic wire is passed through the pipe, the eccentric board and the front cap. When rotating the main body, the front cap and the outer tube are kept still and the eccentric inclined through hole of the eccentric board will drive the elastic wire to rotate. Because of the restriction of the cross-like perforation of the restricting board in the front cap, the elastic wire extending out of the front cap will be rotated and deflected to jump in a knocking manner so as to rotarily dig the obstacles in the water pipe and clear up the water pipe.

Title: Snap-in proximal connector for mounting an optic fiber element into a light source system
Inventor: ROLLER THOMAS W
IPC: G02B6/38
Filed: 1998-03-31
Abstract: The proximal connector (22) includes a stainless steel cone-shaped ferrule (30) enclosing a proximal end (33) of the optic fiber element. The ferrule (30) is inserted within a matching aperture (24) of a receiving block (26) which is also made of stainless steel. The matching shapes of the ferrule (30) and the aperture (24) of the receiving block (26) ensure effective heat transference from the ferrule (30) into the receiving block (26). Both ferrule (30) and the aperture (24) are axially symmetric such that any rotation of the proximal connector (22) while inserted into the receiving block (26) does not change the location of the entrance aperture of the optic fiber element (14).  The proximal connector (22) also includes a case having an indented ring (36).  A ball plunger (42) biasing mechanism is mounted within the aperture (24) of the receiving block (26) and is positioned for engaging with the indented ring (26) only while the proximal connector (22) is fully and securely inserted within the aperture (24). The plunger (42) prevents accidental removal of the proximal connector (22) while also providing a biasing force for ensuring solid contact between the cone-shaped ferrule (30) and the corresponding portions of the receiving block (26) to further facilitate the heat conduction.
