  • Patent number: 10429223
    Abstract: The present disclosure provides an air flow rate measuring device disposed in an intake air passage. The air flow rate measuring device measures a flow rate of the intake air flowing through the intake air passage. The air flow rate measuring device includes a casing, a flow rate sensor, and a sensor module. The casing defines a bypass passage to take in a portion of the intake air. The flow rate sensor is disposed in the bypass passage. The flow rate sensor generates an output signal according to a flow rate of the intake air. The sensor module protrudes from an outer wall of the casing. The sensor module includes a multi-sensor unit that has a relative humidity sensor and a temperature sensor. The relative humidity sensor is exposed to an inside of the intake air passage to detect a relative humidity of the intake air flowing through the intake air passage. The temperature sensor detects a temperature of the intake air flowing through the intake air passage.

  • Patent number: 10104006
    Abstract: In the bus system, bus interface apparatuses and routers are connected together through packet exchange buses which have been established on the integrated circuit. The bus interface apparatuses are respectively connected to transmission nodes which transmit data of mutually different numbers of bits in one cycle of operation of the bus system. Each of the bus interface apparatuses generates and transmits a packet based on data received from the transmission node connected and header information including size information indicating the number of bits with respect to the transmission node connected. The router analyzes the packet, gets the size information from the header information, determines how to allocate a space in the buffer for storage by reference to the size information gotten, and stores the received packet in the buffer.

  • Patent number: 9961005
    Abstract: A bus system (100) for a semiconductor circuit transmits data on a networked bus between a first node and at least one second node via a relay device (250) arranged on the bus. The bus system (100) includes a first bus of a low delay and a second bus of a high delay. The first node generates a plurality of packets by attaching, to the data stored in a buffer (202), information specifying a priority of transmission. The relay device (250) converts a priority based on a priority conversion rule, which is determined based on a transmission delay of the high-delay bus, allocates a buffer of a destination relay device to which each packet is to be sent, based on the converted priority, and sends packets in a descending order. The relay device (250) stores packets in a buffer (252) based on the priority.

  • Patent number: 9819222
    Abstract: A power control apparatus includes the following elements. A measure measures a value of a current to be supplied from a power supply source to a load set. A switch is disposed on a power supply path from power supply source to a load set. A setter sets a first maximum current value in the case of a normal state in which the load set receives power from a main power supply source and sets a second maximum current value when the load set receives power from the sub power supply source. Control circuitry turns OFF the switch when the value of the measured current exceeds the first maximum current value in the case of the normal state and turns OFF the switch when the load set receives power from the sub power supply source and the value of the measured current exceeds the second maximum current value.
