Abstract: A current detection unit that monitors changes in two types of voltage produced by the voltage control unit, and detects and abnormal current flowing due to a potential between the two types of the voltages at both ends of the voltage control unit and an HPG control that receives a control signal of a constant voltage supplied from the information processing device, and transmits a HPG signal to the information processing device based on the abnormal current detected by the current detection unit and the control signal, wherein the HPG signal is a signal indicating a supply state of the direct current power voltage.
Abstract: An optical transmission system, where in an optical transmitter a detection bit having a specific pattern set according to the number of bits to be transmitted within one symbol time, is imparted with respect to a transmission signal in which transmission information has been encoded according to a preset format, and an optical signal generated by modulating light according to the transmission signal is transmitted to a transmission line. In an optical receiver, logic inversion or bit swap of received data is detected and compensated by using the detection bit included in the received signal, a decoding process of the compensated received signal is executed. As a result, when an optical signal capable of transmitting multi-bit information within one symbol time is transferred, it is possible to realize excellent transmission characteristics, by reliably compensating an error in received data caused by the modulation format or the multiplex system of the optical signal.
Abstract: A two-class classification/prediction model is generated in a simple operation by performing two-class classification with a classification rate substantially close to 100%.

Abstract: An electrically commuted reversible synchronous motor is activated in a calibration journey using an externally forced rotating field, during which an electrical angle of a rotating field and a mechanical angle of the rotor are measured simultaneously at a reference position by an external sensor. These items are stored associated with one another as a measurement series of value pairs. The electrical angle of the rotating field and the mechanical angle of the rotor are also detected simultaneously after direction reversal of the rotating field. These are stored as a second measurement series of value pairs. The angle difference between the electrical angle and the mechanical angle are calculated from value pairs of both measurement series. The correction value for taking the actual incorrect angle into consideration is calculated from the two angle differences by averaging.

Abstract: Users of a betting exchange system are permitted to bet on poker and other games in which the game has a number of rounds. For a Texas Holdem poker game, each round allows users to submit bets backing and laying one or more hands of cards during a betting window between game transitions, which result in the display to the plurality of users of selected hole or community cards, depending on the round. After each transition, the hands are evaluated to determine if there are any winners or losers and further betting on selected hands may be permitted, or the game may proceed to settlement.

Also, priority information representing the communication priority of each communication device is received, and the received priority information is associated with the MAC address of the communication device. When no IP address of a transmission source included in a data packet received at each communication port exists in the ARP table, the IP address and the MAC address of the transmission source are added to the ARP table and priority information is attached to the ARP table.
