20140074431 | Wrist Pedometer Step Detection - In some implementations, optimizations for detecting steps when a pedometer is worn at a user's wrist are described. In some implementations, a threshold crossing step detection method can be enhanced for wrist locations by counting the number of positive peaks between comparison threshold crossings, adjusting a minimum peak-to-peak threshold for qualifying threshold crossings, and inferring a second step based on the amount of time between threshold crossings. In some implementations, the pedometer can automatically determine that the pedometer is being worn on a user's wrist. | 2014-03-13 |
20140074432 | ELECTRONIC DEVICE AND METHOD FOR MEASURING OUTLINE OF OBJECT - In a method for measuring an outline of an object, the method creates vectors according to adjacent points of the outline, calculates an included angle between every two adjacent vectors, obtains sampled points in the outline and direction vectors of the sampled points, obtains reference points corresponding to the sampled points, inserts a point between each two adjacent reference points, and creates a measurement program according to the reference points and inserted points. The method further obtains measurement points of the outline of the object using the measurement program, obtains a tolerance of each measurement point and a tolerance of the outline of the object, and displays the tolerance of each measurement point using a graphic user interface. | 2014-03-13 |
20140074433 | DEVICES AND METHODS FOR DIAGNOSIS OF ELECTRONIC BASED PRODUCTS - A device for diagnostic of an electronic based product includes a plurality of sensors for monitoring parameters associated with product. Each sensor generates at least one of an analogue signal and a digital signal upon monitoring of a parameter. The device further includes a plurality of converters for converting analogue signals to digital signals, a processing module for determining abnormal parameter conditions based on comparing digital signals to threshold parameter values.

20140074435 | ACOUSTIC DIAGNOSIS AND CORRECTION SYSTEM - An acoustic monitoring system includes a portable acoustic detection device, a sound analysis device and a confidence level device. The portable acoustic detection device is capable of receiving sound at one or more locations near a sound-producing device. The sound analysis device receives the sound from the portable sound detection device, determines a diagnosis based on a comparison between the sound and pre-recorded sound data, and outputs the diagnosis to the portable acoustic detection device. The sound analysis device also determines a corrective action for inhibiting the sound, which is also output to the portable sound detection device. The confidence level device determines a confidence level of the diagnosis indicating a likelihood that the diagnosis is successfully diagnosed. | 2014-03-13 |
