Abstract: It is known for a gaining machine to issue a ticket or voucher having a value or an associated value as credit. It is a problem that such information carriers may become lost or stolen and subsequently redeemed by others. In the disclosed method, a player first registers and provides a first code to a gaming establishment and a value of credit available with which to play. A ticket is issued with a generated second code. On inserting the ticket in a gaming machine, prior to gaming being permitted, the gaming machine detects the second code and requires the player to enter the first code. The gaming machine validates the codes at the machine against corresponding codes stored elsewhere and permits gaming only when at least one of the codes matches. Thus, a ticket in accordance with the present invention will not be suitable for use other than by the player to whom the information carrier belongs since a third party will not have access to either the player provided code or the generated ticket code.

Abstract: An air purifier has a housing with an inlet for receiving air and an outlet for exhausting air. The housing provides an air flow path for the flow of air in a downstream direction, from the inlet towards the outlet. Particulate pre-filtration is located within the housing downstream from the air inlet. VOC pre-filtration is located within the housing downstream from the particulate pre-filtration. UV filtration is located within the housing downstream from the VOC pre-filtration. VOC post-filtration is located within the housing downstream from the UV filtration. Final particulate filtration is located within the housing downstream from the VOC post-filtration.

Abstract: A discontinuous mode flyback converter for limiting output current using primary feedback is disclosed. A transformer stores magnetic energy using field current and transfers the magnetic energy using a primary winding and a secondary winding closely coupled to the primary winding. A switching element is coupled to one end of the primary winding of the transformer and controls the current of the primary winding of the transformer. A control unit controls the switching element. A voltage error feedback unit feeds back the error of the output voltage of the transformer to the control unit, thereby regulating the output voltage. An output current feedback circuit detects the flyback period of the transformer, detects the output current information of the transformer from the rate of a flyback period in a cycle, and feeds it back to the control unit, thereby limiting the output current of the transformer.

Abstract: A system for applying suction to a wound uses a reference airflow for monitoring system operation. A reference airflow (or “controlled leak”) to the suction source is provided when the system is in operation, such that deviation from the reference airflow can be monitored as an indication of a change in operation, such as a leak in the seal of the wound cover, a blockage of airflow from crimping of the suction conduit or overfill of the waste collector, or an inadvertent turn off or disconnect from the suction source.

Abstract: A computer 12 of an image processing apparatus 11 acquires a moving image including a minor axis cross section of a carotid artery and a cross section of surrounding tissues around the carotid artery and estimates, from images of two temporally different frames of the acquired moving image, an optical flow of each point included in an area corresponding to a carotid artery wall and an optical flow of each point included in an area corresponding to the surrounding tissues. Based on the estimated optical flow of each point, the computer 12 calculates an amount of displacement of the carotid artery and the surrounding tissues with respect to a radial direction of the carotid artery depending on a change in internal pressure of the carotid artery.

Abstract: A multi-protocol RFID interrogating system employs a synchronization technique (step-lock) for a backscatter RFID system that allows simultaneous operation of closely spaced interrogators. The multi-protocol RFID interrogating system can communicate with backscatter transponders having different output protocols and with active transponders including: Title 21 compliant RFID backscatter transponders; IT2000 RFID backscatter transponders that provide an extended mode capability beyond Title 21; EGO™ RFID backscatter transponders, SEGO™ RFID backscatter transponders; ATA, ISO, ANSI AAR compliant RFID backscatter transponders; and IAG compliant active technology transponders. The system implements a step-lock operation, whereby adjacent interrogators are synchronized to ensure that all downlinks operate within the same time frame and all uplinks operate within the same time frame, to eliminate downlink on uplink interference.

Abstract: In an embedded magnet motor, radial magnets and first inclined magnets form north poles. The radial magnets and second inclined magnets form south poles. Core sheets each include preformed radial accommodating slots the number of which is expressed by P/2. Some of the preformed radial accommodating slots are short slots and the rest are long slots. The short slots are located at some parts of each radial accommodating slot along the axial direction. Radially inner ends of the short slots restrict the radial magnets from moving radially inward.
