摘要:
A biometric information process device includes: a biometric sensor obtaining a plurality of biometric images of a user; a detection portion detecting a surface reflection region of the plurality of biometric images; and a storage portion storing biometric information obtained from biometric images included in the plurality of biometric images, the biometric images having a different surface reflection region from each other.
摘要:
A biometric authentication device includes: a biometric information acquisition unit which generates a first input biometric image representing the biometric information of a user, a storage unit which stores data relating to registered biometric information of at least one registered user, and a processing unit. The processing unit realizes a quality judgment function which judges if the first input biometric image is suitable or not for use for comparison of the biometric information represented in the first input biometric image with the registered biometric information, a selection function which selects registered biometric information which is similar to biometric information represented in the first input biometric image among registered biometric information when the first input biometric image is judged unsuitable, and a matching process function which compares the user's biometric information represented in a second input biometric image with the selected registered biometric information.

摘要:
A method, apparatus, and computer program product for transacting a product purchase by a user. The product purchase is processed by a purchase server that recorded a unique user identification and is connected to an information providing server and a client (connected to the user) via a network. The purchase server: receives (from the information providing server) purchase data including purchase identity information including a description of a product selected by the user for purchase; receives (from the client) redirect data comprising purchase identity information describing the selected product; sends (to the client) a request for the unique user identification; receives (from the client) identification data pertaining to the user; authenticates the received identification data pertaining to the user; and validates purchase identity information in the received redirect data. The purchase identity information in both the purchase data and the redirect data does not include the unique user identification.
摘要:
A method of authenticating a user includes storing a reference biometric data of the user, performing initial authentication by obtaining biometric data of the user and comparing the obtained biometric data with the reference biometric data, storing the obtained biometric data upon successful initial authentication, performing second and subsequent authentication by obtaining biometric data of the user and comparing instantaneously obtained biometric data with the reference biometric data and the stored obtained biometric data, and updating the stored obtained biometric data each time the second or the subsequent authentication is successful.
摘要:
A photographing section photographs a photographing object, a light-projector projects a light spot parallel to or approximately parallel to an optical axis of the photographing section onto the photographing object, and a detector detects, from an image of the photographing object photographed by the photographing section, a light spot from the light-projector reflected by the photographing object on the basis of an arrangement position of the light-projector relative to the photographing section. A reflected light spot of light projected onto a detection object can be detected with certainty, and erroneous detection of the reflected light spot, in particular, erroneous detection due to disturbance light, can be prevented at a low cost, without an increase in size of the apparatus.

A head retracting apparatus retracts a head on a storage medium upon detecting a fall. A counter-value calculating unit calculates a counter value that changes with an increase of a falling time and an increase of a non-falling time. A retraction determining unit determines whether to retract the head, based on the calculated counter value.
摘要:
An image taking device with a lighting device includes a light irradiating portion for irradiating light to a subject and a light receiving portion for receiving reflected light from the subject that is irradiated by the light. The light irradiating portion is structured to have a plurality of light sources that are arranged so as to surround the light receiving portion. Each of the light sources is adjusted to emit light of an intensity corresponding to an arrangement position.

This electric power steering apparatus is provided with: a motor; a worm gear provided on a rotational shaft of the motor so as not to rotate with respect to the rotational shaft; a worm wheel gear which meshes with the worm gear and links to a steering system; a gear housing to which a motor housing of the motor is attached, and which accommodates the worm gear and the worm wheel gear; and a decentering device which makes the rotational shaft approach to or depart from a rotational axis of the worm wheel gear in a parallel manner thereto, by rotating the motor housing with respect to the gear housing.
摘要:
A movement controlling unit performs movement control of a head toward a target track on a magnetic disk medium driving a head actuator, and a position controlling unit performs position control of the head actuator in accordance with proportional integral calculations such that a deviation of a head position relative to a track center is eliminated when the moving head arrives at the target track. A gain retaining unit retains an integral gain of the proportional integral calculations in an increased state during a predetermined retention time from the start of the position control, and a gain switching unit switches the increased integral gain smoothly to the original integral gain when the retention time has elapsed.
