Abstract: The disclosed computer-implemented method may include improving safety in operating personal mobility vehicles. The method may track and/or control personal mobility vehicles associated with dynamic transportation networks. The method may improve safety related to PMV operation by taking advantage of the various sources and types of information related to PMV operation that are available in the dynamic transportation network. Other methods, systems, and computer-readable media are disclosed.

Abstract: The disclosed computer-implemented method may include determining the allocation of personal mobility vehicles. By monitoring personal mobility vehicles and determining, based on sensor data from the personal mobility vehicles, the current usage status of the personal mobility vehicles, a dynamic transportation matching system may improve the user experience of transportation requestors relinquishing custody of personal mobility vehicles. In addition, the dynamic transportation matching system may reduce transfer time between personal mobility vehicles and other modes of transportation and/or may improve the availability of personal mobility vehicles across a dynamic transportation network. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: The disclosed computer-implemented method may include matching transportation requests to personal mobility vehicles. A dynamic transportation network may incorporate different types of vehicles, such as bicycles and/or scooters. Certain vehicles may have advantages over other vehicles in certain contexts but be disadvantageous in others. For example, a dynamic transportation matching system may match a user transporting a bulky package with a basket-equipped bike rather than a scooter without a basket. Moreover, the dynamic transportation matching system may account for a wide variety of other factors, including but not limited to route features, ambient conditions, and vehicle status when matching a transportation requestor to a specific vehicle. Moreover, some systems may account for vehicle wear-and-tear, battery power levels, operational status, etc. to avoid matching users vehicles that would be unable to fulfill a transportation request.

Abstract: Personal mobility vehicles, their various components, methods and systems for controlling, using, tracking, and/or interacting with personal mobility vehicles, and methods and systems for integrating personal mobility vehicles within dynamic transportation networks so that a personal mobility vehicle (PMV) can be used in combination with a vehicle of a transportation provider to efficiently complete a transportation request are discussed. For example, a PMV may be used in combination with a lane-constrained vehicle to improve travel time between two locations in situations where the time it may take for a lane-constrained vehicle to reach the starting location may be affected by traffic congestion at the starting location. The PMV may transport a transportation requestor from a starting location to an intermediate location away from the traffic congestion to then transfer to a lane-constrained vehicle for the remainder of the trip.

Abstract: Pyridazinyl-ergoline compounds having neuroleptic activity are obtained by reacting an 8.beta.-tosylmethyl ergoline with the sodium derivative of an aminopyridazine or a mercaptopyridazine in a dipolar aprotic solvent.

Abstract: Novel substituted pyrazine derivatives are disclosed having the general formula (I): ##STR1## where R.sub.1 and R.sub.2 may be methyl, methoxy, halogen (particularly chlorine, bromine or fluorine), or hydrogen, with the proviso that R.sub.1 and R.sub.2 cannot both be hydrogen, and X may be S or NH.These novel substituted pyrazine derivatives show a remarkable activity as inhibitors of platelet aggregation at very low dosages.

Abstract: A process is disclosed for the preparation of a compound of the formula I ##STR1## where R is hydrogen or methyl, X is sulphur or the NH group, Y is selected from the class consisting of methyl, methoxy, chlorine, bromine, iodine, nitro or cyano, m is 0, 1 or 2, and n is 1 or 2, characterized in that a compound of the formula II: ##STR2## where R and n have the above-mentioned meanings, is reacted in a suitable polar aprotic solvent, such as dimethylforamide or dimethylsulphoxide, under a nitrogen atmosphere and at a temperature between 50.degree. and 100.degree. C, with the sodium salt of an appropriate 2-aminopyridine or 2-mercaptopyridine to give, after evaporation of the solvent in vacuo, the desired compound of formula I which is then purified by methods known "per se".The invention also includes the compounds of general formula I, where R, X, Y, m and n have the same meanings, and their pharmaceutically acceptable salts.
