Abstract: A method of tracking a source display panel from which an illegal copy of an image is captured by a camera is provided. The method includes generating a content image visible to human eyes using a visible light component integrated in an integrated light emitting source; generating a watermark image invisible to the human eyes in real time using an invisible light component integrated in the same integrated light emitting source; and simultaneously displaying the content image and the watermark image on the source display panel. Generating the watermark image includes generating an image of an identifier unique to the source display panel. The method further includes analyzing the image captured by the camera to extract the image of an identifier unique to the source display panel; and identifying the source display panel based on the identifier unique to the source display panel.

Abstract: The disclosed technology addresses the problem of testing performance of RU scheduling algorithms used by an OFDMA enabled AP to support multiple clients, using a two-armed test harness with a wired connection to one side of an AP under test and multiple wireless clients coupled in RF communication with the AP. The wireless clients can be connected over the air or conductively to antenna(s) of the AP under test. The test harness generates test traffic. A sniffer radio listens to RU allocation and schedules traffic broadcast by the AP to multiple clients. A recording module records the RU allocation and traffic and a report generator categorizes the recorded resource allocation with the scheduling traffic heard by the sniffer radio and provides resource allocation statistics. The wireless clients are connected conductively or OTA to antennas of the AP under test. One sniffer radio replaces multiple sniffers used in prior test systems.

Abstract: A 3D printer includes a resin reservoir arranged for being filled with a predetermined amount of liquid resin, a light exposure module, and a control processor. The light exposure module includes a plurality of light sources supported above the resin reservoir, wherein each of the light sources is arranged for flashing a discrete image to solidify the liquid resin in the resin reservoir. The control processor controls the light sources to flash the discrete images at the same time and to combine the discrete images into a combined image for forming a layer of a 3D object when the liquid resin is solidified.

Abstract: An air circulation system for a building or other enclosed space that includes an heating, venting and air conditioning (HVAC) unit and a first air duct connecting the HVAC unit with the interior of the building. The system also includes a second air duct connecting the exterior of the building with its interior. A fan or secondary unit directs and moves air from outside of the building to inside the building when a controller determines via one or more sensors that an outside condition is preferable to a condition inside the building. The system also may be used in vehicles such as in ground-based vehicles including public transports, and in aircraft.

Abstract: A method of imaging of a specimen exposed to an electron beam signal includes acquiring an image sequence of sequential images of the specimen. Each subsequent image in the image sequence represents increased cumulative electron beam signal exposure on the specimen. The method includes collecting cumulative exposure data for each image of the image sequence. The method includes applying a low-pass image processing filter to the images of the image sequence using the cumulative exposure data corresponding to each image to which the filter is being applied to produce processed images. The method includes combining the processed images to produce a final image. A method of imaging is also provided that includes selectively discarding images in the image sequence.

Digital encoded-audio bit stream music is played from the RF telephone handset. The digital encoded-audio bit stream music playing from the digital encoded-audio bit stream player is muted when the RF telephone handset receives a telephone call. The RF telephone handset is switched from performing as a digital encoded-audio bit stream player to performing as a telephony device while the telephone call is active.
