Inconspicuous ballistic armor that may be incorporated into or disguised within everyday articles in the environment in which it is deployed. The ballistic armor includes a ballistic shield, an article attached to the front surface of the ballistic shield, and hand/arm straps attached to a rear surface of the ballistic shield. A thin sheet of hardened abrasion-resistant steel may alternatively be affixed to the ballistic shield core and may wrap around the core slightly to allow for attachment of arm straps and hand holds behind the shield. Examples of the article attached to the front surface include a desktop calendar, a whiteboard, corkboard and artwork. The ballistic shield is formed from high strength, lightweight synthetic fiber that can withstand gunfire. The hand/arm straps may be formed from a webbing strap material that is attached, such as by rivets or special fasteners, to the rear surface of the ballistic shield. An autonomous alert and movement tracking system connects the shields to the Internet to allow generation of a map showing locations and movements of shields, and predictive location and movement of the attacker, for use by both the users of the shields and first responders. The shields may also have audio and visual indicators to allow display of alerts.

A sensing system generates location signals indicative of where an electrically-powered, mobile device is in a venue. A control system determines that the mobile device is at rest when the location signals are substantially the same for a predetermined period of time, processes the location signals to determine an accurate, current location of the mobile device in the venue when the mobile device is determined to be at rest, and controls the mobile device when determined to be at rest to operate in a low power mode in which the average electrical power consumption of the mobile device is reduced.

The disclosure relates to detecting and clearing debris from a sensor window. For instance, a system may include the sensor window and one or more processors. The sensor window may include a transparent thin film conductor. The one or more processors may be configured to identify a change in capacitance using the transparent thin film conductor, detect debris on the sensor window using the change in capacitance, and activate a cleaning system in order to clear the detected debris from the sensor window.

Systems and methods for identifying locations and controlling devices are provided. For example, a user may indicate a location by aiming at the location from multiple positions in a physical space. The user may also identify a controllable device to control by aiming at the device. Example systems and methods include determining a first position within a three-dimensional space, receiving a first directional input, and determining a first ray based on the first position and first directional input. Example systems and methods also include determining a second position within the three-dimensional space, receiving a second directional input, and determining a second ray based on the second position and second directional input. Example systems and methods may also include identifying a location within a three-dimensional space based on the first ray and the second ray.

Systems and methods for detecting a site maintenance operation done by a maintenance device are described. At least one motion sensor and at least one localization sensor can each be operatively coupled to the maintenance device to detect one or more motion parameters of the maintenance device via the motion sensor and the localization sensor. The maintenance device can be localized (e.g., its position located) on the indoor map. A movement of the maintenance device can be characterized and/or tracked on the indoor map. A motion map can be displayed to illustrate (e.g., visually represent) the characterized movement. An offsite computer can be used to determine whether the site maintenance operation has commenced at the indoor location, measure one or more maintenance parameters of the site maintenance operation and/or compare the one or more maintenance parameters to predetermined benchmark parameters to determine whether the site maintenance operation has been completed.

A temperature monitoring device for an animal such as a horse including a housing including a body, and a base with an aperture; a temperature sensor at least partly extending through the aperture; wireless communication for transmitting temperature measurements to a mobile device; wherein the base is provided with first attachment for attaching the base to the animal such that the temperature sensor contacts the animal; and the body is provided with second attachment to secure the body to the base via the first attachment.
