Abstract: Provided is an apparatus and method for detecting grout compactness in grouted splice sleeve, the apparatus comprises a probe assembly, which comprises at least one of capacitive probe and piezoelectric sensor and is arranged inside the grouted splice sleeve to detect parameters of the sleeve during grouting and curing and a detector, which comprises at least an analysis module that is connected with the probe assembly to obtain the detected parameters and carry out calculation and analysis for the parameters. The probe assembly is arranged inside the grouted splice sleeve and forms a loop with the detector during grouting, such that during the process of grouting, the detected parameters will be changed as the surrounding dielectric changes, therefore, the detector may determine in real time whether the grouted splice sleeve is fully grouted by calculating and analyzing the detected parameters, which achieves a faster and easier grout compactness detection.

Abstract: A robot apparatus is provided with a photographing device for photographing subjects and a notifying device for making an advance notice of photographing with the photographing device. In addition, in a control method for the robot apparatus, an advance notice of photographing subjects is made and then photographs of the subjects are taken. As a result, a picture can be prevented from being taken by stealth, regardless of user's intention, and thus the user's privacy can be protected.

Abstract: Disclosed is a camera comprising a plurality of controlled devices each operated in at least one of a photographing action and a photographing standby action, the photographing standby action having a first photographing standby action and a second photographing standby action, a release device having a first stroke of outputting a first signal for indicating an execution of the photographing standby action and a second stroke of outputting a second signal for indicating an execution of the photographing action and a control device for repeatedly executing a part of the second photographing standby action through a part of the controlled devices during the outputting of the first signal, repeatedly executing the first photographing action till a predetermined time elapses or till the first signal is outputted when the first signal annihilates without outputting the second signal after the first signal has been outputted, starting an execution of the second photographing standby action when the first signal is
