Abstract: The present invention discloses a packaging structure of a high-power radio frequency device, comprising a plurality of radio frequency power chips connected in parallel and a packaging flange; and the plurality of radio frequency power chips are arranged obliquely in a packaging cavity of the packaging flange, to reduce the number of input bond-wires of the radio frequency power chips, so that the input bond-wires and output bond-wires are not overlapped in space. The plurality of chips are arranged obliquely on the packaging flange, which significantly improves the utilization rate of packaging space and achieves the purpose of high-power output.

Abstract: Systems and methods for transmitting a high quality video image to a mobile device are provided. Some methods can include storing a plurality of images captured by a camera, compressing the plurality of images to generate a compressed video stream file, transmitting the compressed video stream file to a remote device over a network in response to receiving a play video command from the remote device over the network, and transmitting one of the plurality of images to the remote device over the network in response to receiving a pause video command from the remote device over the network.

Abstract: A method and apparatus that includes the steps of receiving a PIR signal and video signal from a passive infrared (PIR) sensor having a PIR detector and camera, displaying a video image from the camera on a display, overlaying a range of the PIR detector and a magnitude of the PIR signal on the displayed video image, displaying a video image of a person walk testing the PIR sensor on the display in conjunction with the overlaid range and a magnitude of the PIR signal provided by the PIR detector and receiving an adjustment from the user of a detection threshold value of the PIR sensor based on the displayed image.
