Title: Method for measuring shape of human body
Inventor: UBUSAWA YOSHIHIRO
IPC: A41H1/02
Filed: 1992-01-27
Abstract: PURPOSE:To accurately measure the three-dimensional, shape or a human body by emitting specific acoustic waves upon the human body wearing clothes and subtracting components other than the reflected acoustic waves from the human body from a plurality of components of detected reflected interference acoustic-wave signals. CONSTITUTION:Acoustic waves of 10kHz are projected upon human body wearing clothes from an acoustic-wave oscillator and the reflected acoustic waves from the human body are found by detecting reflected acoustic waves by means of an acoustic-wave receiver and subtracting components other than the reflected waves from the human body from a plurality of components of reflected interference acoustic-wave signals by arithmetic operations. The distances from the oscillator and receiver to the surface of the human body are found from the reflected signals from the human body. At the time of finding the distances, a change in the phase difference between the oscillator and receiver is used as a distance parameter. When the oscillator and receiver are revolved around the human body, the change in the 'oscillator-human body-receiver' distance becomes several cm. Therefore, when acoustic waves having a long wavelength are used, the distance change becomes shorter than one wavelength and the absolute distance can be measured. When the acoustic-wave information obtained from various points on the surface of the human body are integrated, the shape of the whole human body can be found.

Title: Device for recognizing on-line hand-written character
Inventor: KAMATA HIROSHI
IPC: G06K9/62
Filed: 1989-02-20
Abstract: PURPOSE:To obtain a high recognition rate by extracting a feature point from the order of successively written strokes and using an identification condition on the feature point to decide a character. CONSTITUTION:When input pattern information is applied, a feature point extracting means 1 extracts a feature point and its positional information from the input character pattern information including the order of strokes of the character. An identification condition applying means 5 retrieves an identification condition storing means 4 from a category obtained by a feature corresponding means 3 to find out an identification condition and whether the identification condition for the category is satisfied or not is decided based upon the positional information of the feature point found out by the means 1 and a correspondence recognizing result obtained from feature point correspondence information. Since whether the identification condition is satisfied or not is decided by the relation of feature point positions independently of the number of strokes, continued input characters can also be decided accurately. Thus, on-line character recognition with a high recognition rate can be attained.

Abstract: PURPOSE:To prevent destruction of a switching element caused by heat and embody a cooling structure in a small size and at low cost by lowering the limit value of the heating coil current when the operating cycle period or On duration of the element is short or when the temp. of element is high. CONSTITUTION:In the case using a deep pan as a load where the operating cycle period of a switch element 3 is short and the current in a heating coil 2 reaches its limit value, a control part 9 controls turning on/off of the switching element 3 within the range of a heating coil current limiting circuit 8 which generates limitation to the corresponding control values in N stages according to the results from sensing made by a heating coil current sensing circuit 6 and an operating cycle period sensing circuit 7, and thus the limit value is lowered. The control value is further lowered with the rise of the element 3 temperature when the operating cycle period or the On time is still shorter, and thereby the loss is reduced at the switching element 3, and its destruction due to excessive temp. rise is precluded.
