An apparatus and method for supporting a load-bearing platform (e.g., a seat) and measuring the weight of a load (e.g., an occupant) on the platform. The apparatus can include a base or support, a lever coupled to the support, and a sensor. The lever can be pivotally coupled to the support to allow pivotal movement of the lever with respect to the support in response to weight applied to the platform. The sensor can detect the force transmitted by the lever to determine the weight of the load on the platform. Furthermore, the lever can isolate the vertical load on the platform due to the weight of the load from other extraneous, non-vertical forces on the platform.

By using a refresh request signal RFRQ and an active signal ACT, internal refresh is performed internally in a DRAM separately from an external refresh command. To provide a semiconductor memory device and a semiconductor integrated circuit device capable of simplifying the memory control while securing the sufficient refresh function.

The invention discloses a double-recording video synthesis method of self-service equipment and a double-recording system thereof. The double-recording video synthesis method comprises the steps of: verifying identity validity of a user, if the identity is valid, starting double-recording video recording to obtain a video file; and finally, encrypting the video file and transmitting the encryptedvideo file to the server, wherein collected identity card information is added into a video image in the recording process, a field name mark is generated in the video image, watermark information isadded into video data by adopting a digital watermarking technology, and the watermark information at least comprises face feature encryption information and identity card signature information. According to the double-recording video synthesis method, the client identity card information, client service website information and other information required by auditing of the double-recording systemare automatically captured and added into the video recorded in real time, integrated auditing video information is generated, the background personnel is facilitated to perform one-time auditing, andthe effectiveness of video recording is improved; and meanwhile, the synthesized video is processed by means of encryption and the like, so that the video is not tampered, and the safety performanceis improved.

The invention discloses an absolute position coding and decoding method for an optical grating of an absolute position displacement sensor. The absolute position coding and decoding method comprises the following steps that the optical grating with absolute position coding is divided into N code channels, wherein the first code channel is an absolute code channel, and the other n-1 code channels are equidistant increment code channels; the absolute code channel is composed of a parity bit cross-region identification code area, a gray code area, an interval code area (with or without) and an over-interval code area (with or without); the equidistant increment code channels comprise low-order equidistant increment code channels and high-order equidistant increment code channels which areprovided with evenly spaced scribing lines; the number of the scribing lines of the low-order equidistant incremental code channels is equal to the number of gray codes; the number of the scribing lines of the high-order equidistant incremental code channels can be arranged as required; the corresponding code is "1" when light passes through or reflects from an optical grating absolute code channel coding area to a photoelectric element, and the corresponding code is "0" is when light does not pass through or reflect to the photoelectric element; and during decoding, position data read by thecode channels are integrated through FPGA chips. The absolute position coding and decoding method can ensure that the absolute position coding within any coding length range is unique.

The invention discloses a fish finder comprising a probe device. The probe device comprises a first main control unit, an ultrasonic transducer unit, a coding unit, a surface acoustic wave resonance unit and a first antenna unit. A hand-held part comprises a second main control unit, a radio frequency reception decoding unit and a second antenna unit. A sonar detection angle of the ultrasonic transducer unit is less than 60 degrees. The wireless fish finder adds personal identification numbers of the fish finder to sonar collection information before outputting the sonar collection information to the coding unit, so that different fish finders can indentify whether the information is returned by the probe part of the corresponding fish finder after the different fish finders receive the information, and misreading due to mutual interference of radio frequency information and sonar echoes when two or more fish finders are used in the same water area is avoided.
