The controller may further send a response to the remote device via the communications interface and based upon determining that the user has completed the verification action. The controller may send a notification to the remote device that there is a biometric sensor.

Abstract: A method for monitoring laser light launched into a core of a single mode fiber includes launching a portion of light directly into the cladding about the core. The cladding launched light is a known fraction of the core launched light and can be monitored by placing a detector about the cladding. Detected light including light that was launched into the cladding and has leaked through the cladding is used as a known fraction of light in the core and can be used to control the laser light source. This can be done with a straight section of single mode optical fiber and does not require bending the fiber. Advantageously, most of the core launched light remains in the core as guided light.

Abstract: The invention relates to an electro-optic modulator structure containing an additional set of bias electrodes buried within the device for applying bias to set the operating point. Thus the RF electrodes used to modulate incoming optical signals can be operated with zero DC bias, reducing electrode corrosion by galvanic and other effects that can be present in non-hermetic packages. The bias electrodes are at least partially separated from the substrate with a buffer layer, which in one embodiment has a small amount of conductivity. This conductive buffer layer reduces optical loss from the bias electrodes and also reduces DC drift.

Abstract: A method is disclosed for varying a pulse repetition rate of a passively q-switched laser while maintaining other characteristics of the laser radiation. The laser is optically pumped with a sequence of pump pulses which includes alterations between non-zero power levels and is characterized by two adjustable parameters. By simultaneously changing the adjustable parameters, the pulse repetition rate of the laser can be changed while maintaining the laser pulse energy, divergence of the pulsed laser radiation, and optical spectrum of the pulsed laser radiation at constant levels. In one embodiment, the sequence of pump pulses includes pump power offset which magnitude and/or duration is adjusted when the laser repetition rate is changed.

Abstract: The present invention relates to a delatching mechanism for an electronic module, such as an opto-electronic transceiver or a copper transceiver, for locking the electronic module in a host cage. The delatching mechanism enables a conventional small form factor (SFP) sized module to be unlatched while a cable remains engaged therein. A manually engageable lever, such as a bail handle, is rotatably connected on one end of a pivoting latch, and includes a projection for abutting against the module housing for distributing the force applied to the bail to one end of the pivoting latch, whereby the other end of the pivoting latch rotates away from engagement with the host cage.

Abstract: The present invention relates to a magnetron sputtering device and technique for depositing materials onto a substrate at a high production rate in which the deposited films have predictive thickness distribution and in which the apparatus can operate continuously and repeatedly for very long periods. The present invention has realized increased production by reducing cycle time. Increased coating rates are achieved by coupling a planetary drive system with a large cathode. The cathode diameter is greater than the diameter of a planet and less than twice the diameter of the planet. Lower defect rates are obtained through the lower power density at the cathode which suppresses arcing, while runoff is minimized by the cathode to planet geometry without the use of a mask.
