Abstract: A radio frequency receiving device with automatic gain control includes a filtering module, a radio frequency processing module, a controlling unit and a displaying unit. The filtering module is configured to filter a radio frequency signal to generate a filtered signal. The radio frequency processing module includes an amplifier, a detecting circuit and an automatic gain control circuit. The amplifier amplifies the filtered signal to generate a radio frequency output signal. The detecting circuit detects the filter signal to generate a detected signal. The controlling unit generates at least one intensity signal according to the detected signal, and judges the detected signal to generate an automatic gain control signal. The automatic gain control circuit controls the radio frequency output signal according to the automatic gain control signal. The displaying unit turns on or off a plurality of light emitters according to the at least one intensity signal.

Abstract: An interactive antenna system includes an adjustable antenna device, an antenna control device and an operation device. The adjustable antenna device is for receiving a radio frequency signal wirelessly to generate an antenna signal. The antenna control device measures signal strength of the antenna signal to generate a strength signal, transmits the strength signal wirelessly to the operation device, and controls the adjustable antenna device based on a control signal. The operation device displays the signal strength of the antenna signal based on the strength signal, generates the control signal at least based on an operation performed thereon, and transmits the control signal wirelessly to the antenna control device.

Abstract: A recombinant cytotoxin is provided. The recombinant cytotoxin of the present invention comprises a cytotoxin, a cell penetrating peptide (CPP), and Asp-Glu-Val-Asp (DEVD) sequence inserted in the cytotoxin. The recombinant cytotoxin can induce a targeting cell into the apoptotic pathway and be cleaved by the enzyme generated from apoptotic pathway. The present invention also provides a method for treating cancer, comprising administrating the recombinant cytotoxin to a subject.

Abstract: A panel protection device for accommodating a panel includes a base, a frame fastened to the base, and a monolithic film having an inner edge and an outer edge. The inner edge of the monolithic film is attached to the panel and the outer edge is attached to the frame. The panel is accommodated between the inner edge of the film and the base.
