  • Patent number: 11254321
    Abstract: A driving assist apparatus comprises a driver monitor sensor which detects a state of a driver of an own vehicle installed with the driving assist apparatus. The apparatus determines whether the driver is in a drowsy state, based on the state of the driver detected by the driver monitor sensor. The apparatus determines that a light collision occurs when a light collision determination condition that at least one collision index value representing a level of a collision of the own vehicle is larger than a light collision determination threshold at which an airbag is not developed, is satisfied. The apparatus executes a secondary collision damage mitigation control to apply a braking force to the own vehicle or limit a driving force applied to the own vehicle when determining that the driver is in the drowsy state, and the light collision occurs.

    Abstract: A control unit performs a lane departure suppression control when a host vehicle is about to depart from a traveling lane. The control unit determines whether a low impact collision has occurred. The control unit performs a secondary collision damage mitigation control when the low impact collision is determined to have occurred while the lane departure suppression control is being performed.

  • Publication number: 20210221365
    Abstract: A control unit determines whether a rapid acceleration pedal depression operation has been performed. The control unit determines whether a low impact collision has occurred. When it is determined that the rapid acceleration pedal depression operation has been performed and the low impact collision has occurred, the control unit executes a secondary collision damage mitigation control. Consequently, the secondary collision damage mitigation control can be appropriately executed even when a collision that does not cause an air bag to be inflated has occurred.

  • Patent number: 9184856
    Abstract: Wireless noise is detected within a time period specifically held after a data packet is wirelessly communicated, where no data is purposefully wirelessly communicated during this time period. The time period may be an inter-frame space (IFS) period within which no data is to be wirelessly communicated, and that is a period waited for prior to accessing a wireless medium over which data is wirelessly communicated. One or more actions are performed to counteract the noise. The frequency at which a liquid crystal display is being driven may be decreased so that harmonics caused thereby that caused the noise are no longer within the wireless communication frequency range. An opposite-in-phase version of the noise may also or alternatively be combined with a signal when data is subsequently wirelessly received. The signal includes a data component and a noise component, the opposite-in-phase version of the noise canceling out the noise component.

    Abstract: A device for measuring elastic properties, comprising a long bar-like probe base (42) and probes (50a, 50c) fitted to the probe base (42) driven as to be pressed against and withdrawn from a living body tissue. The probes are so formed that generally semi-spherical contact balls (58) having stress detection bases (56) are fitted to the ends of leaf strings (52) and stress detection sensors (60) are disposed on the stress detection bases (56). Light-receiving elements are fitted to the opposite side of the leaf displacement sensors (62a, 62b). The stress sensors (60) and displacement sensors (62a, 62b) are connected to the device body through signal lines (92, 94), respectively. The profile of the displacement of the tissue is calculated and displayed in a manner indicating correlation with stress.

  • Publication number: 20090272995
    Abstract: An epoxy resin composition for optical semiconductor element encapsulation includes an epoxy resin (Component (A)) mainly containing an epoxy compound represented by a specific structural formula (1), a curing agent (Component (B)), and at least one of an oxynitride phosphor and a nitride phosphor (Component (C)). Therefore, the phosphor component (C) is uniformly dispersed in the epoxy resin composition without segregation. Thus, the resin composition serves as an excellent optical semiconductor element encapsulation material which has an adequate light diffusion property and a high light transmittance and permits a reduction in internal stress. Therefore, a light emitting diode element encapsulated with the epoxy resin composition is capable of stably emitting light, and satisfactorily performs its functions.
