US Classification:

372 20, 372 14, 372 29022, 372102

Abstract:

Tunable external cavity lasers are used in applications such as interferometry, FM spectroscopy, and optical communications equipment testing. Mode hop free high bandwidth frequency modulation operation is desired in a tunable external cavity laser. This application describes new and novel techniques for controlling the output wavelength of a tunable external cavity laser while suppressing mode hop.

International Classification:

H01S 3/115
H01S 3/10

US Classification:

372 12, 372 20

Abstract:

A laser-emitting device may be coupled to an electro-optically controlled wavelength actuator. An electro-optically controlled wavelength actuator may be a holographic wavelength actuator or a liquid crystal wavelength actuator. The electro-optically controlled wavelength actuator may function as a tunable diffraction grating for external cavity lasers.

Abstract:

A floor system includes a pair of joist rim assemblies each having a web defining a first surface. The web also includes a mounting portion defining a second surface offset from the first surface. The joist rim may also include a prong defining a slot along with the web. A joist connector bracket is received within the slot and is connectable to the mounting portion of the web. A joist extends between the pair of joist rim assemblies and is connected to the joist connector bracket of each joist rim assembly.

International Classification:

A61F 2/06

US Classification:

623 112, 623 111, 623 123, 606108

Abstract:

Devices for loading a collapsible implant onto a delivery catheter. In one aspect, a loading device comprises an outer tubular structure and an inner tubular structure. The outer tubular structure comprises a narrowing passage configured to receive a catheter at one end and a collapsible implant at another end. The inner tubular structure is configured to move slidably and co-axially within the outer tubular structure. The inner tubular structure comprises a carrier pin configured to move within the narrowing passage as the inner tubular structure slides into the outer tubular structure. The sliding of the inner tubular structure into the outer tubular structure causes an implant mounted on the carrier pin to collapse as the implant moves through the narrowing passage and into the distal end of a catheter. In an optional aspect, the outer tubular structure further comprises a grasper to stabilize the catheter for receipt of the collapsible implant, and the internal diameter of the inner tubular structure varies to cause the grasper to first contract and stabilize the catheter, and then expand and release the catheter, as the grasper moves into the inner tubular structure.

International Classification:

A61B 17/04

US Classification:

606144

Abstract:

A device for repairing a tear in a portion of tissue comprises a proximal actuator portion, a transfer needle extending distally from the proximal actuator portion and a catch needle extending distally from the proximal actuator portion. A suture needle is disposed in the transfer needle, and is extendable from the transfer needle toward the catch needle and retractable from the catch needle toward the transfer needle. An extendable catch plunger is disposed in the catch needle for capturing suture therein when it is transferred from the transfer needle. A retractable insertion sheath is provided for covering the transfer needle and the catch needle when the device is inserted into a procedural site. A depth limiting apparatus limits the depth of insertion of the needle into the procedural site.
