A foldable stand has a base, a riser, and a switching mechanism. The riser is located on the base. The switching mechanism connects the base and the riser such that the riser selectively pivots relative to the base from an upright position to a folded position. The switching mechanism has a locked status and a released status. In the locked status, the switching mechanism prevents the riser from pivoting relative to the base. In the released status, the switching mechanism allows the riser to pivot relative to the base from an upright position to a folded position. The switching mechanism is configured to be switched from the locked status to the released status by rotation of the riser around a centerline of the riser.

An image capture device includes an audio depression formed into the housing with a drainage microphone mounted therein. A cover protects the drainage microphone disposed beneath the cover from an environment external to the image capture device. The cover and audio depression define a drainage channel extending from a channel entrance, through a channel volume, and out a channel exit. The surface area of the opening of the channel entrance is proportioned relative to the channel volume such that the ratio of the surface area to volume is greater than ten percent. This allows the cover to shift resonance outside of a desired frequency band.

Various examples are provided for surveillance of an audio stream. In one example, a method includes identifying presence or absence of a sound type of interest at a location during a time period; selecting the sound type from a library of sound type information to provide a collection of sound type information; incorporating the collection on a device proximate to the location; acquiring an audio stream from the location by the device to provide a locational audio stream; analyzing the locational audio stream to determine whether a sound type in the collection is present in the audio stream; and generating a notification to a user or computer if a sound type in the collection is present. The device can acquire and process the audio stream. In another example, a bulk sound type information library can be generated by identifying sound types of interest including them based upon a confidence level.

The present disclosure provides a system and method for accurately detecting exercises performed by a user through a combination of signals from a visual input device and from one or more sensors of a wearable device. For each workout type, an algorithm leverages multimodal inputs for automatic workout detection/identification. Using multiple sources of visual and gestural inputs to detect the same workout results in a higher confidence in the detection. Moreover, it allows for continued detection of the workout, including counting repetitions, even when one or more signals becomes unavailable, such as if the user moves out of a field of view of the visual input device.

An equipment recording system is provided with at least one of a microphone and a camera, and a server. The server is configured to store at least one of information on a sound of a measurement target and information on a moving image of the measurement target, which have been stored before and after the time point at which an abnormality-related signal of the equipment has occurred in a state of being associated with the abnormality-related signal of the equipment.
