Abstract: A three-stage snow thrower having a housing, a power supply, a longitudinal drive shaft extending from the power supply into the housing, and a lateral drive shaft extending between opposing side walls of the housing and being meshingly engaged with the longitudinal drive shaft within a gear assembly. The first stage assembly includes a plurality of augers attached to the lateral drive shaft for pushing loosened snow axially toward the gear assembly. The second stage assembly includes at least one auger attached to the longitudinal drive shaft for pushing snow from the first stage assembly axially rearward. The third stage assembly includes an impeller that rotates to throw the snow through a chute attached to the housing to expel the snow from the housing.

Abstract: Described are handheld devices with combined image capture and image projection functions. One embodiment includes modulating and capturing a light beam along the same optic path. In another embodiment, the optical components are operable to switch between projection and capture modes. In yet another embodiment, the optical components may be formed on the same semiconductor substrate thereby increasing functionality.

Abstract: A method of determining a location of a network condition within a wireless mesh network is disclosed. The method includes a test device testing a first plurality of wireless hops of the wireless mesh network. The test device also tests a second number of wireless hops of the wireless mesh network. The test device locates the network condition within the wireless mesh network by comparing the test of the first plurality of wireless hops with the test of the second number of wireless hops.

Abstract: A film forming material can be used for the preparation of a medicament for pre-treating an area of skin to reduce causes of skin irritation, resulting in a educed risk of acquiring skin chafing and/or blisters. A method of pre-treating can comprise the steps of: providing a dispensing device containing a film forming material; and applying a film forming material to an area of skin, for pre-treating an area of skin to reduce friction and thereby reduce the risk of acquiring chafing and/or a blister.

Abstract: A kit and method for a two-step acne treatment regimen. The kit comprises a wash composition and a cream treatment composition. The method comprising the steps of: using a wash composition to clean acne affected skin of an individual; and applying a cream treatment composition to the acne affected skin.

Abstract: Methods of correlating wireless network performance of a wireless network are disclosed. One method includes collecting wireless network performance parameters at a location of the network, observing at least one of activities and conditions of the wireless network over the period of time, and correlating the wireless network performance parameters with at least one of the activities and conditions of the wireless network. The wireless network performance parameters can be collected by one or more test devices operating at nodes or clients within the wireless network.

Abstract: A nozzle for use with a walk-behind blower includes a nozzle restriction due to a sloped upper wall of the nozzle body. The nozzle restriction increases the air velocity in the upper region of the nozzle and forces leaves and debris downward so that airflow through the lower region of the nozzle more effectively laterally displaces them. The configuration of the nozzle body may be adapted to accommodate a variety of engine outputs while utilizing a common design for a blower frame, impeller and shroud.

Abstract: A combination blower assembly and string trimmer whereby the string trimmer head is easily detachable without the use of any tools. The device includes a blower assembly that further includes an upper and lower housing mated together to form a volute-shaped cavity where an impeller with airfoil-shaped blades reside. The detachable string trimmer head is located under the lower housing of the blower assembly and is easily attached or removed from the blower assembly by a simple push and turn motion. The blower assembly further includes an air inlet and air inlet cover. When the air inlet cover is rotated to a position where the air inlet is open the blower assembly is operable and the string trimmer is inoperable. Furthermore, when the air inlet cover is rotated to a position where the air inlet is closed the blower assembly is inoperable and the string trimmer is operable.

Abstract: An improved blower with a directional output nozzle is provided for various tasks such as moving debris or drying surfaces. The blower includes a frame mounted on wheels and a motor mounted to the frame. The blower also includes a housing with an inlet opening and directional output nozzle. An impeller is located in the blower housing and is driven by the motor to generate airflow. As the impeller rotates, air is drawn in through the inlet opening and is discharged through the output nozzle. The output nozzle can be repositioned by rotation by either local control or remote actuation.
