The present disclosure generally relates to providing perceptual notifications containing information about a measured activity-based value of a swim characteristic. In some examples, the perceptual notifications utilize colors and haptic taps to convey measured values of the swim characteristic without requiring the swimmer to interact with the perceptual notification while the swimmer is swimming.

A system includes a computer having a processor and a memory storing instructions executable by the processor to acquire a first image of a tire of a vehicle upon shutdown of the vehicle. The instructions include instruction to then, upon startup of the vehicle, and in response to determining that the tire is unmoved since the shutdown and, in response, acquire a second image of the tire. The instructions include instruction to actuate a component of the vehicle in response to determining that the first image is different that the second image.

Implementations of firearm regulation systems may include a firearm safety system (FSS) configured to physically couple to a firearm. The FSS may include a locking mechanism configured to prevent the firearm from firing and a sensor configured to detect an environmental parameter. The firearm regulation system may also include a management system communicatively coupled to the FSS and a site safety system (SSS) communicatively coupled to the management system. The SSS may include one or more lockdown mechanisms.

Aspects discussed herein relate to providing alerts to a community of devices located in or near a geographic are such as a building or property. The alerts override any alert-inhibiting state of the mobile device to deliver audio, visual, and/or haptic alerts in emergency situations. The communication and emergency alert system may be used to communicate with many different communities of people. Moreover, certain individuals may be members of more than one community at the same time, and the communities themselves may change over time based both on the user's preferences and on their physical locations. A variety of application programming interfaces can be provided to allow third-party applications to generate, transmit, and display alerts that override any alert-inhibiting state of a mobile device.

Moreover, certain individuals may be members of more than one community at the same time, and the communities themselves may change over time based both on the user's preferences and on their physical locations. Multiple different alerts can be sent to different mobile devices for a single event. The alerts can be customized to particular mobile devices depending on the community to which the mobile device belongs for the event.

A reminder device includes a frame-shaped base defining an opening and configured to be mounted over and around an operational button/handle located in a vehicle or in a home; a lid coupled to the frame-shaped base and configured to close over said frame-shaped base, covering said opening and blocking access to said operational button/handle; a circuit configured to product an audible message upon receiving a trigger signal, said circuit being located in at least one of said framed-shaped base and said lid; and a switch including a first component located on said frame-shaped base and a second component located on said lid and so configured that when said first component and second component are separated from each other by a predetermined distance, when the lid is opened, the switch causes the creation of said trigger signal and the production of said audible alarm.
