Patent CA-2354756-A1 (CA)
Title: Optical device package
Inventor: LIBERTY JONATHAN
IPC: G02B6/36
Filed: 2001-08-03
Abstract: To ensure the best optical coupling during the assembly of optical devices, such as WDM couplers, the elements making up the optical device are mounted with their longitudinal axes offset from each other, resulting in no two devices having identical structures. Moreover, it is also common for one of the elements to have a larger diameter than another.  Therefore, it is very difficult to provide a package that will be satisfactory for every one of the optical devices. Furthermore, current manufacturing techniques require labor intensive steps that include one or more gluing or welding steps. Accordingly, the present invention provides an optical package that is suitable for optical devices with slightly varying structures, and that can be assembled relatively quickly and easily. The present invention relates to a package for an optical device, comprising two mating sections, each section including a rigid outer protective shell, and a resilient inner body. The package is easily clamped together using snap clips, which are integral with the rigid outer protective shells. Preferably, strain relief is provided integrated on each end of the resilient inner bodies.

Patent CA-2363105-A1 (CA)
Inventor: MAEDA HIROYUKI
IPC: A61N1/30
Filed: 2000-02-16
Abstract: A device for iontophoresis capable of detecting the state of conduction accurately. A voltage compartor (10B) detects the presence of inactive curre nt by a comparison between an output current signal (18) indicative of an inactive current flowing in the skin or the mucous membrane and a threshold level (SL) preadjusted to the voltage value corresponding to the lower inactive current. When the output current signal is higher than the threshol d level, the voltage comparator produces "H" as its output signal (11B) to inform a control circuit that the state of conduction is normal. When the output current signal is lower than the threshold level, the voltage comparator produces "L" as its output signal (11B) to inform the control circuit that the state of conduction is abnormal.
