A method for controlling an operation of a compressor and its apparatus can easily control an operation of the compressor without a request for a high-priced operation control apparatus by operating the compressor with controlling the amount of currents flowing into a winding coil of a motor (100) of the compressor according to load capacity of the refrigerator. The apparatus includes a control unit (103) for generating a control signal for selecting a main winding coil (M) of a linear motor (100) of a compressor or an auxiliary winding coil (M2) on the basis of the load capacity of a refrigerator, and a switching unit (101) for selecting the main winding coil (M) of the linear motor (100) or the auxiliary winding coil (M2) on the basis of the control signal. Herein, the main winding coil of the linear motor (100) is divided into a plurality of auxiliary winding coils (M2).
Abstract:
This invention relates to a user authenticating system and a method using aone-time fingerprint template. The system and the method according to the invention are improvements of the conventional user authentication based on the manner of comparing the fingerprint feature data only, for the purpose of preventing a false authentication by misusing fingerprint feature data, if exposed in the course of transfer thereof. In the system and the method according to the invention, fingerprint feature data of a user are combined with an OTT key transferred from a server. The combined result is encoded and transferred to an authenticating server. The authenticating server then confirms validity of the OTT key and authenticates the user based on the fingerprint. Thus, the present invention has an advantage of preventing a false authentication through hacking, etc., even if the OTT key is exposed to a network, because the OTT key is used only once for authentication.

Disclosed is an optical fingerprint acquisition apparatus capable of reducing an image distortion and a size of an optical system by deforming the shape of a prism. The prism according to the invention includes a fingerprint contacting surface to be touched by a fingerprint of a person, a totally reflecting surface facing the fingerprint contacting surface with an angle &thgr; for totally and inwardly reflecting the light scattered from the fingerprint in contact with the fingerprint contacting surface, a primarily projecting/re-incident surface linking the fingerprint contacting surface to the totally reflecting surface with an angle &phgr; for primarily projecting the light totally reflected from the totally reflecting surface so as to be re-incident from outside, and an ultimately projecting surface facing the primarily projecting/re-incident surface for ultimately projecting the light re-incident to the primarily projecting/re-incident surface toward outside.
Abstract:
The present invention relates to a method of producing paste containing flaky aluminum powder, which is the main ingredient of the topcoat paint for automobiles. The present invention is intended to provide a production method, which is more economical than the conventional method of using the gas-atomozied powders. In particular, a vessel is charged with by-product scraps from the production process of aluminum foil, balls, mineral spirits, and an unsaturated fatty acid, such as oleic acid. Under such conditions, the ball-milling is carried out to yield an intermediate paste containing flaky aluminum powder, which is then made into aluminum paste by adjusting the amount of a solvent.
