A snowplow having a snow removal mechanism, the snowplow comprises: an obtainment unit configured to obtain topography information prior to snow accumulation; and a projection unit configured to, based on the topography information prior to snow accumulation obtained b the obtainment unit, project an image indicating the topography information prior to snow accumulation on a surface of accumulated snow that is to be removed by the snow removal mechanism.

A wearable visual communications unit for automatically presenting information visually to third parties, the visual communication unit including a visual display, a microprocessor, a memory unit, a location tracker module in communication with the microprocessor, and a command signal generating unit in communication with the visual display, where the location tracker module is configured to track location of the wearable visual communication unit and is configured to generate location based data, where the micro-processor is operable to receive the location based data and to execute code stored in the memory unit to select a required visual presentation, and where the command signal generating unit is configured to generate at least one command signal to control the visual display to present the required visual presentation.

A person lifting apparatus includes a first lifting strap feeding device including a first drum and a first lifting strap wound on the first drum. A second lifting strap feeding device includes a second drum and a second lifting strap wound on the second drum. A controller is communicatively coupled to the first lifting strap feeding device and to the second lifting strap feeding device. The controller includes logic that controls operation of the first lifting strap feeding device and the second lifting strap feeding device based on a comparison of current draws of the first lifting strap feeding device and the second lifting strap feeding device.

Disclosed are breathing apparatus comprising lighting systems. Lighting modules are provided to illuminate in vertical and horizontal directions and to illuminate in a first lighting pattern if the determined status condition is a normal status condition and in a second lighting pattern if the determined status condition is an alert status condition.

The purpose of the present application is to provide a notification system that is for buildings, that can be introduced and widely used in ordinary collective housing and office complexes without the need to make a large investment in equipment, and that enables an emergency event taking place in a building to be detected by passersby passing the vicinity of the building. An emergency event display device equipped with a large screen display is installed in a position that is visible to passersby passing outside the building. When there is some emergency event in the building, an indication of the emergency event is displayed on the display device upon receipt of notification from a residence or a common use space where a notification means is installed. A display of the display device normally shows an ornamental picture or video so as to soothe the residents walking in and out of the building or the passersby passing in front of the building, whereby an impression of the building can be bolstered. The display device is made noticeable not only to residents but also to passersby passing in front of the building so as to make it possible to report an emergency event in an efficient way and consequently provide safety for the residents.

A power tool includes a battery pack, one or more sensors, an indicator, and an electronic processor coupled to the battery pack, the one or more sensors, and the indicator. The electronic processor is configured to: detect, using the one or more sensors, one or more parameters of the power tool; determine a system performance based on the one or more parameters; determine a system performance level based on the system performance; and provide, using the indicator, an indication corresponding to the system performance.

Introduced here are containers designed to promote compliance with regimens for administering the medications stored therein. These containers have various features that allow them to be more easily managed by the individuals to whom the medications were prescribed. Some features improve the ease with which containers communicate with individuals. These features may enable information to be more easily input by individuals and/or output for individuals in a comprehensible manner. Other features improve the mechanical or electrical durability of containers. Such features may enable the containers to be used by individuals over the course of several days, weeks, or months without worrying about structural damage or loss of power.

An exemplary method and system is disclosed that facilitates a readily-re-deployable and self-enclosed geofencing and proximity-based intrusion sensing and alerting system in a roadway or construction work zone. The sensing and alerting system is configured in the form factor of a safety cone, barricade or drum to sense and uses acoustic-echoes or LiDAR-based sensing to detect intruders that are in proximity to the sensing and alerting system to generate a siren or loud audible alert, as well as flashing lights, to warn workers of such intrusion.
