Abstract: A resource management device includes a processor configured to update registered process information indicating priority of a process being executed and an area in a shared resource used by the process, at every start or end of execution of one of processes using the shared resource, determine, when a first process being executed rewrites data stored in the shared resource, whether a second process using an area in the shared resource used by the first process exists, by referring to the registered process information, interrupt the first process until termination of the second process when the second process having higher priority than the first process exists, and interrupt the second process until termination of the first process when the second process having lower priority than the first process exists.

Abstract: A vehicle controller includes a memory configured to store a priority table representing degrees of priority of a plurality of processes related to automatically driving or assisting in driving a vehicle for each road section or for each possible situation around the vehicle; and a processor configured to determine a road section where the vehicle is or the situation around the vehicle according to the position of the vehicle or a sensor signal generated by a sensor mounted on the vehicle for detecting the situation around the vehicle, determine degrees of priority of the processes, depending on the road section where the vehicle is or the situation around the vehicle, by referring to the priority table, and execute the processes sequentially in descending order of priority of the processes, using a shared resource.

Abstract: A content player calculates control duration during which control at a current control level continues, the current control level being one of a plurality of control levels of a travel control unit that controls travel of a vehicle; selects a piece of content such that time required for playback is shorter than the control duration, from among a plurality of pieces of content; and plays back the selected piece of content by an output device mounted on the vehicle when travel of the vehicle is controlled at the current control level.

Abstract: A sound bar includes a housing, a rotary member, first and second speaker boxes, and a gear mechanism. The rotary member is rotatable with respect to the housing. The first and second speaker boxes are slidable with respect to the housing, respectively. The first and second speaker boxes are disposed at opposite end portions of the housing in a lengthwise direction of the housing, respectively. The gear mechanism is disposed between the rotary member and the first and second speaker boxes. The gear mechanism is configured to slide both the first and second speaker boxes with respect to the housing in opposite directions of the housing along the lengthwise direction of the housing in response to a rotational movement of the rotary member.

Abstract: A method of making fibrous alkali titanate comprising the steps of melting a mixture of titanium compound and alkali compound at a temperature higher than 1000.degree.C, cooling the melted product so as to form a glassy material, pulverizing the resultant glassy material, treating the pulverized powder in an autoclave in the presence of water at a temperature at least higher than 350.degree.C so as to form fibrous alkali titanate, and washing the treated product.
