A craft is provided with a lever that can control the power / speed of the craft and semi-automatically transition the craft in various modes of operation. This makes control of the craft somewhat similar to control of a boat, thereby bringing a maritime flight control experience to a wing-in-ground effect vehicles, hydrofoiling vessels, seagliders, and seaplanes. Further, various audio, visual, and / or haptic devices in the cockpit can provide alerts / feedback to the operator on the use of the lever and mode transitions.

Inconclusive and inconsistent results from existing haptic testing systems, e.g. for trackpads, which include rigidly mounted resistive load cells and accelerometers, prevent accurate results, especially in a high-volume production context. The use of a rigidly mounted sensor is unsuitable because a trackpad will generally be softer than the actuation system, whereby, when the haptic event is fired, the vast majority of the energy will be lost in the trackpad, while the sensor remains almost stationary. Accordingly, an improved test probe for a haptic device configured for mounting on a robotic arm, comprises: a contact tip configured for contacting the haptic device; a sensor configured for measuring a threshold force of the piezoelectric actuator device, and an haptic characteristic, e.g. acceleration, of a resulting haptic response thereof at a same time and a same location; and a compliant element configured for enabling the sensor to move relative to the haptic device.

This application discloses a tactile sensor and its fabrication method. The tactile sensor includes a tactile membrane, an optical window, a cavity, a deformation structure, and a capacitor structure. The cavity is enclosed by a cavity wall and two opposing openings at both ends. The two openings respectively house the tactile membrane and the optical window. The deformation structure is located within the cavity and is used to absorb energy from an external light source. Under photothermal action, it deforms, thereby displacing the tactile membrane to generate tactile stimulation that can act on a target object. The capacitor structure converts the tactile stimulation into an electrical signal for tactile information acquisition. This application utilizes the deformation structure to deform within a certain temperature range, thereby displacing the tactile membrane and converting light energy into tactile output. This avoids the dependence of traditional light-driven tactile devices on closed air cavities, gas expansion, and suspended light-absorbing sheets, improving the structural stability and driving efficiency of the tactile sensor and increasing its environmental adaptability.

In a digital analysis of chewing, based on feedback principles and preferred optical marker position recognition, the interdependent movement patterns of maxillary and mandibular teeth are analyzed using bidirectional synchronization of tactile and motion image acquisition technologies, and their movements are recorded by a camera system. The camera system preferably integrates at least two systems, one on the right side of the mouth / face and the other on the left side, or one system is centered relative to the facial centerline. Each system has at least one (preferably three) camera, including at least one and preferably two monochrome or color cameras with a minimum resolution of 2.3 Mpx and a high frame rate of at least 1000 frames per second (FPS), equipped with dedicated optics / lenses, and at least one high-resolution and low-frame-rate color camera with a minimum resolution of 12 Mpx and a minimum frame rate of 25 FPS, capable of recording markers (M1) indirectly fixed by positioning patterns, or markers directly / independently (M2 – preferably using IPA technology) affixed to the veneer surface of the crown of the maxillary natural / artificial tooth, and markers independently affixed to the veneer surface of the crown of the natural / artificial tooth. Because of the connection between the camera and the trigger card, their operation is synchronized in time and is responsible for recording the position / movement of the upper crown with M1 and / or M2 markings relative to the lower crown with M1 and / or M2 markings, as well as the position / movement of the upper and lower crowns with M1 and / or M2 markings relative to the alveolar bone of the upper and lower jaws and the patient's face with M2 markings, the markings being affixed to facial feature anatomical points. This is all recorded synchronously in video film technology, and then the 3D scans of the upper and lower teeth with M1 and / or M2 markings are stitched into the video film, wherein the scans are obtained through intraoral or extraoral scanning technology. Furthermore, it can convert the repositioning of M1 and / or M2 markers. Movements during patient chewing assessment are recorded by a camera system, and the captured images are transcribed into a software environment.

This is preferably read by a tactile device, preferably a tactile manipulator, to map / control the repositioning caused by these collisions via vibrations at a frequency between 1 and 4 kHz. The above arrangement enables the tracking of the amplitude of height changes in the collision angle, which is above / below 10 degrees between the upper and lower crown pairs with M1 and / or M2 markers, within a set time unit, divided into time intervals, preferably 0.001 seconds. Along the path of each movement phase / chewing cycle, the number of vibrations of the tactile manipulator during the set time unit represents the contact / collision moments of these crown pairs with M1 and / or M2 markers.

Each camera set includes three cameras spaced at predetermined distances. Each set has two monochrome or color cameras with a maximum resolution of 2.3 Mbps and a high frame rate of at least 1000 FPS, equipped with dedicated optics / lenses, and one color camera with a minimum resolution of 12 Mbps.
