The same file system as that used with the AG-CX350 Professional Handheld Camcorder will automatically create filenames 20 characters in length for easy control of clips. Conventional AVCHD acquisition is also supported.
Six files preset with picture quality settings are provided as Scene Files (Standard, Shooting under fluorescent lights, Spark, STILL-LIKE, CINE-LIKE contrast, and CINE-LIKE dynamic range). You can change any of the settings as desired and store one set as a Custom File in the camcorder.
The AG-CX10 supports the MXF P2 file format for broadcasting. Main recording with AVC-Intra or AVC-LongG codec and sub (proxy) recording with AVC-Proxy G6 codec can be recorded simultaneously. Despite the low bit rate of 12 Mbps or 6 Mbps, the proxy data has the same angle of view and resolution as the main recording, enabling highly immediate breaking news.

Tests on subject FS001. Subject FS001 movement phases during the drinking task (Additional file 2). From left to right: initial position (a), reaching of the cup (b), grasping of the cup (c), cup to mouth (d), releasing of the cup (e) and return to initial position (f).

During the second experimental session, the subject tested the Hand NMES module to assist the opening of the hand which was not possible by his own volitional control. This session was repeated twice on two different days (FS001_test 6 and 7 in Table 3 and Additional file 3). On both days, the hand was correctly opened and closed by the stimulation. After the first day of stimulation the subject reported a positive reduction of the rigidity of the hand with the possibility to better use it to drive the wheelchair.
Figure 6 shows the results of the drinking task (left column) and of the touching the left shoulder (right column) with the support of the exo. The breaks were activated automatically to keep the position once reached the mouth/shoulder to allow some resting to the subject and the possibility to keep the position and the function longer. The EMG activation profiles of the biceps and of the three deltoids muscles are reported in panels b), c), e) and f). It can be noticed that the subject relaxed the biceps some seconds after the activation of the brakes when she actually realized their activation.
Tests on subject RF002. Subject RF002 angles and EMG signals measured during the drinking task (panels a-c) and the touching the left shoulder task (panels d-f), with the support of the exo. In panels a) and d) the angles profiles are reported, the vertical lines limit the phase of the brakes activation. The correspondent EMG signals of the biceps and anterior deltoid (panels b) and e)) and of the medial and posterior deltoid (panels c) and f))are reported.
In the first session (ND004_test 1 and ND004_test 2 in Table 3. Additional file 6), the subject used scenario 2 configuration, he exploited the exo and the muscles of his right arm were stimulated with the sequential feedback control strategy to accomplish the drinking task. The subject used the eye tracking module to select the object to be grasped and to trigger the different sub-actions. The grasping and the releasing of the object were performed with the help of the operator. From MUNDUS perspective, this test aimed to testing whether the stimulation was able to assure the reaching task completion in the case of a subject with partial muscle atrophy. Figure 8 reports the results achieved during the first test performed by the subject. Pictures of the subject in three specific instants of the movement are shown: initial position (panel a), cup to mouth (panel b) and return to initial position (panel c). The figure reports also the angles profiles (panel d), the correspondent muscles stimulation (panel e) and the breaks activation (panel f) used to execute movement.
Just after second 80, a sudden sliding of the shoulder horizontal rotation angle (red line in panel d) can be observed even if the correspondent brake was activated (red line in panel f). This was due to the fact the brake was not strong enough to block such a big arm. A similar problem occurred also with some healthy subjects and a new version of the horizontal shoulder brake was then integrated into the prototype. The performance of the second test improved in the second half of the drinking task a sit can be seen in the Additional file 6.
This subject is a quadriplegic male of 33 years old with an incomplete SCI (C7 level) since 2011. The subject is classified as an ASIA Impairment Scale A with right and left motor/sensitive level C7. He has no residual voluntary control of his right arm and hand. Both his arm and hand muscles were completely flaccid, i.e. no muscle tone was present (see MRC scores in Table 1), and he was an NMES-responder only at the arm level. Thus, the selected scenario was Scenario 3, since the instability of his trunk control prevented the possibility to use efficiently the eye tracking module, and he tested the robotic hand orthosis. The subject carried out two experimental sessions. During the first session, the subject visited the rehabilitation centre on three consecutive days. Familiarization with the robotic orthosis, adaptation of the orthotic interface with the subject and adjustments of the orthosis as well as of the exo were the goals of the first day. On the second and third day, the subject was asked to perform two different test cases. The first test case (GC008_test 1 in Table 3, Additional file 9) involved the donning procedure of the orthosis as a stand-alone module, the GUI-guided calibration of an open, a closed and a relaxed hand position and a therapist-triggered grasp and lift movement of the drinking cup to verify the holding of the object. The grasping was not stable in this test. The same steps were performed during the second test case with the robotic orthosis mounted on the exo (GC008_test 2 in Table 3). In this second test the grasping was reliable, while the release was not completely accomplished and required the help of the operator. The arm movement for reaching the object was aided by the operator for both test cases. On the second day, the presence of the exo had no adverse effects on the performance of the tests: the cup could be securely grasped and held while the operator was moving his arm. Figure 11 shows an example of the measured MCP and PIP angles during the calibration and the subsequent grasp&hold phase. To calibrate the three hand postures, the operator incrementally increased or decreased the actuated MCP joint angle by 4 and set the values by clicking on the corresponding button on the GUI screen. The starting points of the blue arrows mark the time and angular values of these clicks. In the subsequent testing phase, the corresponding relax, open and close commands were sent to the controller. The final angles deviate from the reference angle by approximately 6 due to an implemented tolerance band and mechanical clearance. The flexible thumb brace did not always hold the thumb in a position such that it did not interfere with the cup handle. In those cases, the operator had to manually extend the thumb.

During the second experimental session, the subject tested the combination of the exo with the robotic hand orthosis and the stimulation of the arm muscles by means of the sequential feedback controller. The use of the robotic hand with the stimulation of the arm muscles (GC008_test 3 in Table 3) showed that the weight of the robotic orthosis prevented the possibility to perform the whole drinking task, since once the subject was reaching the mouth the weight of the hand system was causing a slight humeral rotation changing the orientation and preventing the correct action of the gravity to drive the return to the table sub-action. Afterwards the subject tested the following reaching tasks, without the hand module: touching the left shoulder, touching the left hand, and pushing a button (GC008_test 4 to 6 in Table 3, Additional file 10 and Additional file 11). In these last trials the Scenario 3 configuration was tested, using BCI to control the system. He was able to complete successfully all these latter tasks and to select and confirm actions by means of BCI with an accuracy of 100%.
