Abstract: A display light measurement method which can measure color representation of a various types of display devices regardless of the specification of the display device; a computer program, and a measurement system. A measurement device connected to an optical sensor can communicate with a target display device (information terminal) to be measured. The measurement device transmits content including a color patch to the display device to cause the display device to display the content and performs a measurement on the displayed content using the optical sensor. To perform measurements on many color patches, the measurement device repeats the following: when a measurement on one color patch being displayed is complete, the measurement device transmits content including another color patch to the display device to cause the display device to display the content and performs a measurement on the content being displayed.

Abstract: A charge/discharge device switches between allowing and disallowing charging/discharging of an electrical storage unit by switching a relay with a drive circuit. The device, specifies at the time of an anomaly that prevents the relay from operating normally, the portion in which the anomaly has occurred. A charge/discharge circuit performs a charge or discharge operation on an electrical storage cell in response to instructions. A drive circuit generates a drive current where a drive instruction is given, and supplies the drive current to a relay. A control unit controls the instructions that are given to the charge/discharge circuit and instruction that is given to the drive circuit. An anomaly specification unit specifies the portion where an anomaly has occurred based on the power source voltage that is input to the drive circuit, output that is provided from the drive circuit to the relay, and the voltage of a charge/discharge path.

Abstract: A communication device is provided in a wireless multi-hop network. The communication device receives a sequence number, a divided time acquired by dividing a time width allocated for transmitting detected usage data by a division number, and the division number. The communication device calculates a remainder by dividing the received sequence number by the division number and calculates a transmission offset time based on the remainder and the divided time. The communication device transmits the usage data based on the calculated transmission offset time.

Abstract: The present invention increases accommodation efficiency in a wireless master station for wireless slave stations, and efficiently uses wireless resources while controlling traffic. In a communication system in which a plurality of wireless slave stations 2-1, 2-2, 2-3, . . . , perform wireless communication with wireless master stations 1-1 and 1-2 directly or through another wireless slave station and which performs communication from the wireless master stations with a collection control device 3 by means of wired communication or the like. The collection control device 3 stores first through fourth threshold values a, b, c, and d in memory, and makes efficient use while suppressing traffic by performing a “connection suppression notification”, a “specific high-frequency communication stop notification”, and an “accommodation refusal notification”, and performs functionality control through stages according to the number of accommodated wireless slave stations.

Abstract: A power supply device that is capable of discerning the presence or absence of an abnormality in a specific converter included in multiphase converters, and an abnormality determination method for the power supply device. In the case where a switch Sja is turned ON/OFF for a time period of such that an output voltage supplied to a battery and a load by a single converter out of n converters CV1, CV2, . . . , and CVn connected in parallel equals a target voltage, it is determined whether or not the difference between the output voltage and the target voltage is greater than a predetermined threshold value. Based on the result of this determination, whether or not an abnormality is present in the converter that has performed the control for turning ON/OFF the switch Sja is determined.

Abstract: A control unit performs calibration when a determining unit determines that an absence condition of an operator is satisfied. Calibration is performed to a whole or part of brightness, a white point (gain), gamma (gradation), and primary colors (red, blue, and green colors). The control unit stores a correction amount by calibration in a storage unit, measures the (corrected) calibrated brightness or color tone by using an optical sensor, and stores the measured final measurement result in the storage unit as a corrected measurement value. After performing calibration or when the determining unit determines that a presence condition of the operator is satisfied, a profile generating unit generates color space information.
