摘要： A method for measuring a distance between a coordinate indicator and a coordinate input device, which belongs to the technical field of computer peripheral equipments. The method comprises the steps of measuring an actual amplitude of an output signal of a receiving coil in the electromagnetic induction plate by a measurement circuit in the electromagnetic induction plate; determining a distance between the coordinate indicator and the coordinate input device in accordance with the actual amplitude of the output signal, a nominal amplitude of the output signal, and a preset reference amplitude of signal. In the present invention, the distance between the coordinate indicator and the coordinate input device is determined by converting an actual amplitude of the output signal of the receiving coil at one time to a nominal amplitude of the output signal normalized by a reference amplitude of signal, which overcomes the defect of the prior art which can not indicate a distance between the coordinate indicator and the coordinate input device.

摘要： A method is disclosed for checking model planes entering into a dive, as well as an anti-dive method and apparatus. The method of checking planes includes installation of a first optical sensor in the upper part of the plane, with installation angle upwardly intersecting with the front of the plane at α degrees, that checks light intensity and outputs a first checked optical signal; installation of a second optical sensor in the bottom part of the plane, with its installation angle downwardly intersecting with the back of the plane at β degrees, which checks light intensity and outputs a second checked optical signal. A comparison is made between the first and second checked optical signals, and when the difference in light intensity is smaller than a threshold, a warning signal is sent out indicating that the plane has entered into a dive.

摘要： In a digital signal processing system, a method for selecting a transform function to apply to an input signal based on characteristics of the signal, and for self-adjusting criteria which are used in selecting a transform function to apply to a subsequent signal. Characteristics are obtained from the signal. The characteristics are compared to adjustable criteria which are used in selecting a transform function. Differing criteria are maintained for the different selectable transform functions. A record is maintained of transform functions selected and the particular characteristics that caused the selection. Based on the ability of a transform function to minimally define the coded signal, an inverse transform function is selected to decode the signal. The criteria used in selecting a transform function to apply to a subsequent signal are adjusted based on a quality measure of the decoded signal and the record of selected transform functions.

摘要： Techniques for performing combined scaling, filtering, and/or scan conversion are disclosed that reduce the amount of line buffer space required in the overall design of a video processing system. In particular, coefficients from all or a sub-set of the scaling, filtering (smoothing/sharpening), and scan conversion filters are combined into one representative coefficient that can be applied in a single generic algorithm. Thus, implementation costs are reduced, particularly in a system-on-chip implementations.

摘要： An aerial drone having a flying platform and has detachable and interchangeable cabins. Each cabin can have an energy storage unit that supplies energy to the flying platform so the when cabins are exchanged, a fresh supply of energy is made available to the flying platform. The flying platform and the cabins can have motorized wheels as well as floatation devices for water landing.
