Abstract: Methods and systems for monitoring use, determining risk, and pricing insurance policies for a vehicle having one or more autonomous or semi-autonomous operation features are provided. According to certain aspects, an identity of a vehicle operator may be determined and a vehicle operator profile and/or operating data regarding autonomous operation features of the vehicle may be received after the vehicle operator opts into a rewards program and agrees to share their data. Autonomous operation and vehicle operator risk levels associated with operation of the autonomous or semi-autonomous vehicle may be determined. Based upon the risk levels and/or comparison thereof, one or more autonomous operation features may be disengaged. A preparedness level of the vehicle operator to assume or reassume control of operating the vehicle is determined prior to disengagement. If satisfactory, an alert is presented to the vehicle operator prior to disengagement of the autonomous operation features.

Abstract: According to certain aspects, a computer-implemented method for operating an autonomous or semi-autonomous vehicle may be provided. With the customer's permission, an identity of a vehicle operator may be identified and a vehicle operator profile may be retrieved. Operating data regarding autonomous operation features operating the vehicle may be received from vehicle-mounted sensors. When a request to disable an autonomous feature is received, a risk level for the autonomous feature is determined and compared with a driver behavior setting for the autonomous feature stored in the vehicle operator profile. Based upon the risk level comparison, the autonomous vehicle retains control of vehicle or the autonomous feature is disengaged depending upon which is the safer driver—the autonomous vehicle or the vehicle human occupant. As a result, unsafe disengagement of self-driving functionality for autonomous vehicles may be alleviated.

Abstract: A barrette for holding hair having an improved wireform latch in which the barrette includes a top plate having upstanding pivots and upstanding receptor hooks, and the wireform being a semirigid wire in a frogleg shape which is put in tension parallel to the plate by compressing the legs together to allow hooking of the legs to the pivots and in rotary tension away from the plate by compressing hair between the plate and wireform by such hooking.

Abstract: Curing agents for epoxy resins composed of (a) the reaction product of a co-reactant comprising either an epichlorohydrin (co) polymer or a (co)polymer of a chlorovinyl acetate, chloroalkyl acrylate with an organic amino compound containing at least one active hydrogen and having a pK.sub.B value within the range of from about 7 to about 9, preferably imidazole and substituted imidazoles; (b) an N-fatty imidazole and (a); (c) an N-fatty imidazole and an elastomeric polymer are disclosed. The curing agents are essentially water insoluble and give rise to epoxy resins which may be cured at relatively low temperatures below about 100.degree. C. The epoxy resins are suitable for use as adhesives, coatings and in composite applications.
