Filed:

Aug 22, 2001

Appl. No.:

09/935418

Inventors:

Tracy E. Brewer - Hayward CA

Assignee:

WaveSplitter Technologies, Inc. - Fremont CA

International Classification:

G02B 626

US Classification:

385 43, 385 39, 385 42

Abstract:

A system and method for twisting together two fibers to create an optical fiber coupler is disclosed. In one embodiment, the two optic fibers are threaded through a chuck, which is rotated by a motor to create an amount of twist in the two optical fibers necessary to cause a light signal transmitted through the twisted fibers to have a desired polarization state. A heater applies heat to the twisted fibers while rotating the chuck to create an optical fiber coupler.

International Classification:

G02B 600

US Classification:

385147, 81 941, 81 951, 30 901

Abstract:

A method and apparatus is described for stripping the coating of an optical fiber. A fixture having a fiber cleat may be used to secure an optical fiber to enable removal of the protective coating from the fiber along a precise length of the fiber. The length of protective coating removal may be controlled by a strip guide. A stop coupled to the apparatus also controls how much of the coating is removed.

Assignee:

Wavesplitter Technologies, Inc. - Fremont CA

International Classification:

B23K 2620

US Classification:

21912163, 21912164, 21912183

Abstract:

A method is described that involves scanning a laser beam across and applying a stretching force to a fusion region that is formed by a neighboring pair of optical fibers that include a core and a cladding layer. The scanning and applying occurs while the optical permissiveness of an optical path that flows through the fusion region is monitored.

International Classification:

A61M 5/172

US Classification:

604 67, 604151

Abstract:

Some embodiments of an infusion pump system may be configured to detect when at least one component of the pump system is exposed to an impact above a threshold level. In particular embodiments, the infusion pump system can be equipped with an impact detection system that can sense when an impact above the threshold level has occurred to the pump device, which thereby enables the infusion pump system to initiate appropriate patient safety countermeasures.

International Classification:

G01N 2100

US Classification:

3562371

Abstract:

The present invention provides an optical detection system for detecting surface qualities on an optical fiber. The system comprises a light source for projecting a beam of light onto the outer surface of an optical fiber. An optical detector positioned adjacent the optical fiber receives light reflected from the outer surface of the optical fiber and generates an electrical output signal which is delivered to a signal processing device. The signal processing device analyzes the electrical output signal to determine whether one or more surface qualities exist on the outer surface of the optical fiber. In accordance with the preferred embodiment of the present invention, the optical detection system is used to detect surface qualities that include ink skips, i. e. , locations on the outer surface of the optical fiber that do not contain any ink. The signal processing device comprises a computer that records the intensity of the light received by the optical detector array, which corresponds to the magnitude of the electrical signal generated by the optical detector array, along with the location along the optical fiber that corresponds to the electrical output signal.

US Classification:

356237

Abstract:

The present invention provides an optical detection system for detecting defects in an optical fiber. The system includes a light source for coupling light into the secondary coating of an optical fiber at a preselected angle with respect to the longitudinal axis of the fiber and an optical detector positioned adjacent the fiber at a preselected distance from the point at which the light is coupled into the fiber coating. In accordance with one embodiment, the light is coupled into the fiber coating at a sufficiently shallow angle with respect to the longitudinal axis of the fiber to cause the light to travel through the coating in a direction substantially parallel to the axis of the optical fiber for some distance before exiting the coating. By placing the detector a preselected distance from the coupling point, detection of light reflected from the fiber at the coupling spot is avoided and only light reflected by defects contained in the primary or secondary coating layers, or light reflected by delaminations between the primary coating layer and the fiber, will be detected by the detector.

International Classification:

H04N 718

US Classification:

358108

Abstract:

A vehicular surveillance system comprising a video recorder and monitor in a housing mounted within the passenger compartment of the vehicle to a bracket and a small camera rotatably mounted to the windshield of the vehicle. An FM microphone transmits audio signals to the vehicle's antenna whence it is carried to the recorder by a cable and added to the video images. Date and time information is superimposed on the video image on the top right of the image so as to interfere as little as possible with the image being recorded. The video recorder has a locking mechanism to prevent ejecting the video cassette by unauthorized personnel and its on/off switch is combined with the start record/stop recording function so that one button applies power to the system and starts the recording after a short delay. The housing may be removed from the vehicle for portable use in presenting recorded events as evidence and both video recorder and monitor may operate on the car battery or standard household current.
