Abstract: A travel teaching recording method includes detecting by a pause controller whether or not an operator has performed a stopping operation of a pause switch, stopping traveling of a cleaning machine and controlling timing to stop recording in a storage if the stopping operation of the pause switch is detected, detecting whether or not the operator has performed a resuming operation of the pause switch, starting traveling of the cleaning machine and controlling timing to resume recording in the storage if the resuming operation of the pause switch is detected, and joining the record before stopping recording and the record after resuming recording so as to store the joined record in the storage.

Abstract: A path generating method includes setting a moving direction at each of two positions, setting a first turning circle with one of the positions as a contact point and the moving direction as a turning direction, setting a second turning circle that is within a specific area, setting a Dubins path that starts from a predetermined point of the second turning circle or ends at the predetermined point, and selecting, as a movement path, a path that is within the specific area among paths each including the first turning circle and the Dubins path.

Abstract: A main body of a ball collecting and discharging machine includes a traveling portion and a ball collecting and discharging portion to collect and discharge balls. A controller causes the ball collecting and discharging portion to collect the balls scattered in a ball scattered area while causing the traveling portion to cause the main body to travel along a ball collecting route in the ball scattered area. When the ball collecting and discharging portion reaches a state of being ready to discharge balls during or after ball collecting work, the controller causes the traveling portion to cause the main body to travel along the ball discharging route and causes the ball collecting and discharging portion to discharge balls at the ball discharging site.

Abstract: An autonomous vehicle executes a teaching travel mode to store a route traveled by an operator's manual operation and an autonomous travel mode to autonomously travel on a planned traveling route. A ball collection route travel schedule creator creates a planned traveling route from a teaching route obtained by the teaching travel mode. A difference calculator calculates differences in position coordinates and posture angles between an arbitrary point designated by an operator and a current position. A display displays the differences calculated by the difference calculator.

Abstract: A ball collecting and discharging machine plans and travels on an autonomous traveling route in a designated region. A main body includes a travel motor. A ball collecting route travel schedule generator generates a ball collecting route along which the autonomous travel vehicle repeatedly reciprocates in a main direction in a traveling region. A travel controller moves the main body along the ball collecting route by controlling the travel motor. A route generator generates a ball collecting route including lap routes coupled together while shifted in a sub direction intersecting the main direction in the traveling region. Turn-around positions in the main direction of the respective lap routes include at least one set of turn-around positions shifted from each other.

Abstract: The present invention provides a process for making a mineral battery using treated powdered polar crystal mineral and a treated liquid as an electrolyte. The polar crystal powder and liquid are either separately or after mixing together subjected to a rotating EMF. The powder-liquid mixture is inserted into a housing and compacted therein to form a mineral battery, along with an anode and a cathode and terminals. The preferred polar crystal mineral is tourmaline. In one embodiment, after the mixture is in the housing it is subjected to a voltage. In one embodiment the mixture is prepared and compacted into the housing and then subjected to a rotating EMF, and may then also be subjected to application of a voltage.

Abstract: When carrying out pre-processing of image signal transmission using the control channel of a full-duplex modem and switching image signal transmission to the primary channel of a half-duplex modem, the answer modem stops the transmission carrier upon confirmation that all “1” signals with 40 bit or more have been received from the calling modem, restarts the reception of all “1” signals after the elapse of a certain period of time, confirms the end of all “1” signals and switches to the primary channel.

Abstract: An encoding (or decoding) method, by which raw data of 1 line is converted into, for example, modified Huffman (MH) code (or MH code is converted into raw data) by obtaining a cumulative run-length code every transition point, at which there occurs a transition or change between a run of white pixels to another contiguous run of black pixels, from the beginning of the line and then converting the cumulative run-length code to the MH code (or converting the MH code to the cumulative run-length code). The cumulative run-length code is defined by both of data, which indicates that a pixel of a run just prior to the transition point is black or white, and data representing a cumulative run-length of the run up to the pixel thereof just prior to the transition point. Thus, an encoding or decoding processing can be performed at a high speed.

Abstract: A Viterbi decoding method, in which consecutive input data bits Q.sub.6n .about.Q.sub.1n are first converted into consecutive code bits Q.sub.6n .about.Q.sub.3n Y.sub.2n Y.sub.1n Y.sub.0n at a time instant n by use of a Trellis encoder. Then, a branch metric, which is a minimum Euclidean distance between a reception signal point and each of signal points (namely, Trellis codes Q.sub.6 .about.Q.sub.3 Y.sub.2 Y.sub.1 Y.sub.0) in a signal space diagram, corresponding to each of eight states 0 to 7 and a corresponding signal point are obtained. Further, a sum of the branch metric corresponding to each state and a corresponding path metric at a time instant (n-1), which is a sum of corresponding branch metrics since a time instant 1 to the time instant (n-1) is calculated. Then, the path metric corresponding to each state is updated by replacing it with the calculated sum of the corresponding branch metric and the corresponding path metric obtained at the time instant (n-1).
