20130033580 | THREE-DIMENSIONAL VISION SENSOR - Enabling height recognition processing by setting a height of an arbitrary plane to zero for convenience of the recognition processing. A parameter for three-dimensional measurement is calculated and registered through calibration and, thereafter, an image pickup with a stereo camera is performed on a plane desired to be recognized as having a height of zero in actual recognition processing. Three-dimensional measurement using the registered parameter is performed on characteristic patterns (marks m | 02-07-2013 |
20130094705 | Method and Apparatus for Projective Volume Monitoring - According to one aspect of the teachings presented herein, a projective volume monitoring apparatus is configured to detect objects intruding into a monitoring zone. The projective volume monitoring apparatus is configured to detect the intrusion of objects of a minimum object size relative to a protection boundary, based on an advantageous processing technique that represents range pixels obtained from stereo correlation processing in spherical coordinates and maps those range pixels to a two-dimensional histogram that is defined over the projective coordinate space associated with capturing the stereo images used in correlation processing. The histogram quantizes the horizontal and vertical solid angle ranges of the projective coordinate space into a grid of cells. The apparatus flags range pixels that are within the protection boundary and accumulates them into corresponding cells of the histogram, and then performs clustering on the histogram cells to detect object intrusions. | 04-18-2013 |
20130113382 | SOLID STATE RELAY AND LOAD DRIVE CIRCUIT - A solid state relay includes a light-receiving element, output terminals configured to connect to an AC power supply and a load, a first connection line connecting a first end of the light-receiving element to a first output terminal, a second connection line that connects a second end of the light-receiving element to a second output terminal, a switching element between the first connection line and the second connection and configured to be turned on by the current outputted from the light-receiving element, and a snubber circuit in which a capacitor and a resistor are connected in series. The resistor of the snubber circuit connects to the first connection line between one of the first and second end of the light-receiving element and an end of the switching element, and an over-current protection element connects to the first connection line between the resistor and an end of the switching element. | 05-09-2013 |
20130113581 | CONTACT SWITCHING MECHANISM AND ELECTROMAGNETIC RELAY - To promptly extinguish an arc generated between contacts with a simple and inexpensive structure without negatively influencing the spring property of a movable contact piece. A contact switching mechanism includes a fixed contact piece with a fixed contact and a movable contact piece with a movable contact which faces the fixed contact in a contactable manner. At least either one of the contact pieces is provided with an extension which extends toward the contact of the remaining contact piece. | 05-09-2013 |
20130140167 | TRIGGER SWITCH - Embodiments of the invention provide a trigger switch in which a trigger is pulled into a housing so as to operate a contact mechanism, thereby driving a motor of an electric drill. The inside of the housing is divided into a first region including a circuit in which a main electric current for driving the motor flows, and a second region including the contact mechanism of a signal circuit which controls a rotation of the motor. An air vent is disposed on an outer circumferential surface of the first region of the housing. The trigger switch can reduce operational failure due to dust and the like without making the structure thereof complicated. | 06-06-2013 |
20130182942 | METHOD FOR REGISTERING INSPECTION STANDARD FOR SOLDERING INSPECTION AND BOARD INSPECTION APPARATUS THEREBY - Performing an inspection based on a shape of a solder fillet and setting a standard of the inspection. In order to set the standard of the inspection by a method for determining whether the solder fillet of a component mounted on a board is proper by obtaining a calculation of a numerical parameter indicating a three-dimensional shape of the solder fillet, a setting screen including an image display region indicating an image of a component of a setting target and an inspection standard list is displayed to receive a user manipulation. A list in which an item name of each of plural inspection items is correlated with an input field of a standard value of a numerical parameter measured by the inspection item is displayed in the inspection standard list. | 07-18-2013 |
20130189024 | CONNECTION STRUCTURE OF HOUSING OF ELECTRONIC APPARATUS AND CONNECTION METHOD OF FORMING HOUSING - A connection structure of a housing of an electronic apparatus and a connection method of forming a housing, both of which are able to secure a desired strength by integrally combining even end surfaces of an opening edge portion of a thin-wall housing into one piece with ultrasonic welding is disclosed herein. The connection structure of the housing of the electronic apparatus is formed by matching end surfaces of opening edge portions of a first case and a second case and integrally combining the end surfaces into one piece in a welding manner. Particularly, a welding protrusion rim protruding along an end surface of an opening edge portion of the second case is melted to be welded on a welding fitting groove, on which a crimp process is performed along an end surface of an opening edge portion of the first case, for integration into one piece. | 07-25-2013 |
20130199907 | OPERATION SWITCH - An operation switch where a switch unit can be separated from an operation unit in a simple manner even when the operation switches are densely fitted is disclosed herein. The operation switch of the invention includes an operation unit that is disposed on a front surface side of a panel and operated by external pressing force, a switch unit that can be separated from a rear surface side of the panel from the operation unit, a latching unit formed on an external circumferential surface of the operation unit along an axial center direction, a latching receiving unit which is formed along an external circumferential surface of the switch unit and to which the latching unit is latched, and a release lever that releases a latching state of the latching unit and the latching receiving unit so that the switch unit is separated from the operation unit. | 08-08-2013 |
