An impulse scraper and scraper arrangement for scraping a foreign body off the mating running surface of a machine part is disclosed. The impulse scraper has a holding section and a scraper lip with a scraper edge, extending around the central axis of the impulse scraper, for dynamically contacting and scraping the foreign body off the mating running surface. The scraper lip is intrinsically elastically deformable and, on its peripheral side facing away from the holding section, has one or more annular material weaknesses, each defining a predetermined bending zone of the scraper lip. The scraper lip itself forms an axial stop for a respective longitudinal segment of the scraper lip arranged distally with respect to the axial stop. Alternatively, the scraper lip is arranged on the holding section via a support element, the axial deflection movement of which relative to the holding section is limited by an axial stop.

A cleaning method for a surveillance camera uses a capacitive sensor to determine whether rain, ice, dirt, debris or other foreign objects are present on the camera lens substrate. A determination is made whether the sensed capacitance is greater than a first threshold indicative of the presence of a foreign object on the lens. If a foreign object is indicated, the lens is sprayed with a sprayer and then a wiper is activated. If a foreign object is not indicated, a determination is made whether ice is present by comparing the sensed capacitance to a second threshold that is less than the first threshold. If ice is present, wiper and lens defrosters are activated, and a wiper is then turned on. The cleaning method may include a temperature sensor and power management for the defrosters.

The present invention relates to a multi-tool having a frame with a first leg opposite a second leg. The frame also includes a first handle at a proximal end of the frame, a support at a distal end of the frame, and a second handle positioned between the proximal and distal ends of the frame. The first handle, second handle, and the support are positioned between the first and second legs. A squeegee member is positioned on the first leg, a first brush is positioned on the second leg, and a second brush is positioned on the support. A scraper extends from the support at the distal end of the frame proximate the second brush.

The present invention relates to a cleaning arrangement for a nozzle of a vacuum cleaner. The cleaning arrangement comprises a socket for receiving the vacuum cleaner nozzle and a cleaning member arranged in the socket for removing articles entangled to a rotatable member of the vacuum cleaner nozzle during rotation of the rotatable member.

Described embodiments include an unmanned aerial vehicle and a method. The unmanned aerial vehicle includes an airframe and a rotary wing system coupled with the airframe and configured to aerodynamically lift the vehicle in the air. The unmanned aerial vehicle includes a flight controller configured to control a movement of the vehicle while airborne. The unmanned aerial vehicle includes a cleansing controller configured to manage a removal of a surface contaminant from a selected portion of a surface of an external object using an airflow generated by the rotary wing system.

This disclosure relates to techniques for implementing a windshield wiper system with an actively movable platform. The windshield wiper system can include a windshield wiper arm mechanically coupled to a platform and an actuator mechanically coupled to the platform. The windshield wiper arm can be configured to move through a planar range of motion that is substantially parallel to a surface of a vehicle when the platform is positioned at a first spatial location and the movable windshield wiper arm can be configured constrained from moving through the planar range when the platform is positioned at a second spatial location.

A wiper system incorporates a wiper motor provided with a wireless interface to provide electric power and control signals to the wiper motor. Thus, a direct electric/signal wire connection to the wiper motor is eliminated. A wireless transmitter may be provided within a first body portion of a vehicle and a wireless receiver and a wiper motor are provided in a second body portion of the vehicle. The second body portion may be moveable relative to the first body portion, such as, for example, a lift gate moving relative to a body opening.

A cleaning device is provided that includes a housing, a cleaning head, a flexible pouch, a cleaning element, and a nozzle. The housing defines an internal cavity having a power source in selective electrical communication with a pump. The flexible pouch is removably stored in the housing and includes a cleaning fluid therein. The pouch forms a fluid and air tight connection with an inlet of the pump. The cleaning element is connected to the cleaning head and has a first opening. The nozzle is in fluid communication with an outlet of the pump. The nozzle is positioned on the cleaning head so as to release the cleaning fluid from the flexible pouch through the first opening onto a surface being cleaned.

An improved device and method for gathering up loose pet hair, lint, and other fine debris from a variety of surfaces. In the preferred embodiment, the device includes a handle and a blade. The blade is made of an elastromeric material that is flexible. Exposed surfaces of the blade have a rough, crinkled, pebble-grain texture, such as crepe rubber. The blade is greater in height than in thickness; greater in width than in height; and wider at the bottom end than at the top end, where it is connected to the handle. The handle of the device is held by the user, while the bottom end, side ends, or front and back surfaces of the blade are placed on the surface to be cleaned and dragged with slight pressure across the cleaning surface. The blade dislodges, grips, and gathers up loose pet hair and other fine debris into a wad so that it may be removed by hand or by vacuum suction.
