摘要:
A distance measuring device having a light projector and a light receptor, at least one of which is caused to move so that when the intersection of their optical paths is disposed at an object, its coincidence is detected by the signal generated in the light receptor for measuring the distance from the device to the object based on the triangulation. In order to obtain a clear peak signal, according to the invention, for the light source, use is made of a light energy distribution characteristic which is higher at the marginal zone than at the central zone.

There is disclosed a vertical synchronizing signal detector circuit for use with a PCM recording/reproducing system which records and reproduces audio signals with pulse code modulation by the use of a home VTR system or a part thereof. The vertical synchronizing signal detector circuit comprises an input terminal for receiving a composite synchronizing signal including a horizontal synchronizing signal and a vertical synchronizing signal, an output terminal for providing a vertical synchronizing pulse synchronized with the vertical synchronizing signal, a clock pulse generator circuit connected to the input terminal and adapted to generate a clock pulse having half the period of the horizontal synchronizing signal and a phase lag therefrom of one-fourth the period thereof, a vertical synchronizing signal extractor circuit connected to the input terminal and the clock pulse generator circuit and adapted to compare the vertical synchronizing signal with a reference waveform pattern for the vertical synchronizing signal so as to generate a vertical synchronizing signal output synchronized with the vertical synchronizing signal only when the comparison results in a complete coincidence, and a vertical synchronizing signal compensator circuit connected to the vertical synchronizing signal extractor circuit and the clock pulse generator circuit and responsive to the vertical synchronizing signal output to provide this output at the output terminal and simultaneously store the same temporarily, the vertical synchronizing signal compensator circuit being also adapted to provide the stored vertical synchronizing signal output at the output terminal when the vertical synchronizing signal output is not received, whereby the vertical synchronizing pulse is produced at correct timing even if the vertical synchronizing signal is absent in the composite synchronizing signal because of a dropout or the like.

摘要:
Example systems and methods relate to a multi-player video game in which multiple players each supply inputs to a respective input device to control a corresponding game character in a scrolling-type game world displayed on a display screen. A first predetermined input supplied by one of the players to the respective input device protects the one player's game character from harm in the game world and the protected game character moves based on the scrolling/non-scrolling state of the game world in accordance with the movement of one or more unprotected characters. The protecting of the one player's game character is stopped in response to one or more protecting stopping conditions, whereby the game character is again controllable by the one player in response to inputs to the respective input device.
