In an example, an optical gimbal is described, the optical gimbal comprising: a pulse generator configured to generate at least two coherent beam splitting pulses; a first optical beam director configured to tilt the vector of the beam splitting pulses by an angle θ; an atom source configured to allow the beam splitting pulses to manipulate trapped atoms within the atom source; a processor configured to receive the angle θ, and control the pulse generator and the beam director; a detector coupled to the atom source configured to measure a final population of the atoms in different states.

The arm motion sensor system includes at least one sensor attached to the body and positioned to detect arm motions, a control system for detecting when the arm motion is characteristic of a bad habit or activity that may spread infectious disease, and an alert system warning the user to refrain from such activity. In one embodiment, the sensor attached to the wrist and includes a 3-degree of freedom, 9-axis inertial measurement unit and an Edge TPU (Tensor Processing Unit). The wrist sensor communicates with a control system in the Cloud that includes an Artificial Intelligence (AI) unit that is trained to recognize undesirable motions. The wrist sensor includes an alarm system (tactile, auditory, or visual that warns the user to refrain from undesirable arm movements. Optionally, this system may also include an infrared sensor and WiFi MCU (microcontroller unit) positioned near the neck to screen out acceptable arm movements.

Systems and methods relating to sensors for measuring acceleration. Two attached containers are each filled with different liquids. At each junction of the two liquids, an indicator is placed. When acceleration forces are applied to the sensor, the indicator moves when the boundary between the two liquids similarly move. The amount of movement of the boundary and of the indicator is proportional to the amount of acceleration for applied. A tracking subsystem tracks the position of the indicator and, by determining the amount of movement of the indicator, the amount of acceleration force applied can be calculated. The indicator can be a particle or it can be a beam-like element that deflects when the boundary between the two liquids move.

A foam sensor device is used for monitoring foam within a vessel. The sensor (e.g. accelerometer) is encapsulated inside a water-tight, sterilizable, shell, which floats on a liquid contained. In one example, the foam sensor device includes an accelerometer for detecting and measuring rotation and movement of the foam sensor device and generates movement data based on the detected movement. During a learning or calibration process, sensor data (e.g., movement data) from the foam sensor device is analyzed and classified using machine learning and/or signal processing methods to extract features indicative of different possible foam statuses, including varying levels of foam, or no foam and generate models for the different statuses. During normal operation, the foam sensor device transmits sensor data to an analyzer containing the pre-calibrated models, which determines whether there is foam or not. Based on the foam status, a pump controller adds anti-foam solution.

Impact or acceleration sensor, which contains a liquid droplet and is designed such that the position and/or distribution of the liquid indicates whether an impact or any other acceleration of a predetermined minimum magnitude has occurred, includes: first and second foils, a cavity disposed between the foil faces of the foils and at least one retaining structure disposed on the foil face of the first and/or second foil and functions to maintain the liquid in a predetermined first sub-volume of the cavity. The retaining structure is a region of the first and/or second foil formed as a local elevation, depression or irregularity of the foil face, which forms a passable barrier for the wetting and/or contacting of the first and/or second foil by the liquid and defines an area piece of the foil face of the first and/or second foil corresponding to the first sub-volume.

An accelerator position detection device includes a handlebar grip that is turnable in a normal rotation direction and in a reverse rotation direction from a neutral position and is energized to the neutral position when no operation is applied; accelerator position sensors that output voltage according to an angle of the handlebar grip and that include a first sensor and a second sensor; and a detector that detects an angle for control for controlling a vehicle on the basis of the angle of the handlebar grip according to output from the accelerator position sensors. The detector detects an angle as a positive value on the basis of a first voltage when the first voltage in a rising range is output, and the detector detects an angle as a negative value on the basis of a second voltage when a first initial value not located in the rising range is output.

Shock indicator device for a watch, internal to the watch, including a structure, to which is fixed an inertia block by means of at least one connecting element made of elastic or ductile or breakable material, which is elastically and plastically deformable when movements are imparted to the inertia block, this inertia block being movable in proximity to a fixed opposing surface comprised in the structure itself or in another element of a watch case, and arranged to come into contact with this opposing surface, to impart a proof indicator of impact or a permanent deformation or damage to the inertia block and/or to the connecting element and/or to the opposing surface, and/or to a breakable element incorporated in the shock indicator device), when the acceleration imparted to this inertia block is higher than a given acceleration threshold.
