TARGET-DESIGNATION DETECTION USED TO SHUTTER CAMERA IMAGES FOR LOCATING TARGET
20170370677 · 2017-12-28 ·

Apparatus and associated methods relate to a seeker for a Semi-Active Laser (SAL) guided missile. The seeker has a Short-Wave InfraRed (SWIR) camera and a Pulse Timing Logic (PTL) detector. The PTL detector has a SWIR photo detector axially aligned with a lens stack of the SWIR camera. The SWIR photo detector is configured to detect a sequence of SWIR pulses generated by a SAL target designator and reflected by a designated target. The PTL detector has a pulse timer configured to identify a sequence pattern of the detected sequence of SWIR pulses, and to predict a timing of a next SWIR pulse in the identified sequence pattern so as to synchronize exposure of the SWIR camera to capture a next image of the designated target at the predicted timing of the next SWIR pulse. Such exposure timing can advantageously improve the signal to noise ratio of the next image.

Coating for light security

A night vision system includes an eyepiece and a video camera to capture a video image that can be remote to the eyepiece. The eyepiece includes an optical device with a front side and a back side. A splitting surface within the optical device reflects some of a video image toward an eye of a user of the eyepiece, and the splitting surface further allows some light of an optical image received from in front of the eyepiece to past through the eyepiece to the eye of the user. The layer of switchable coating on the eyepiece can be switched between a transparent mode and an opaque mode by the user. When in an opaque mode no light can leave the front side of the optical device and only the video image can be seen through the eyepiece.

Electric shaver with imaging capability
09848174 · 2017-12-19 · ·

System and method for improving the shaving experience by providing improved visibility of the skin shaving area. A digital camera is integrated with the electric shaver for close image capturing of shaving area, and displaying it on a display unit. The display unit can be integral part of the electric shaver casing, or housed in a separated device which receives the image via a communication channel. The communication channel can be wireless (using radio, audio or light) or wired, such as dedicated cabling or using powerline communication. A light source is used to better illuminate the shaving area. Video compression and digital image processing techniques are used for providing for improved shaving results. The wired communication medium can simultaneously be used also for carrying power from the electric shaver assembly to the display unit, or from the display unit to the electric shaver.
