20100205769 | SURFACE TREATING HEAD ASSEMBLY - A surface treating head assembly for an appliance such as a vacuum cleaner includes a head and a drivable agitator in the form of a brush bar, rotatably housed in a housing. A motor is arranged to drive a mechanism, such as cams arranged to adjust the position of the brush bar with respect to the housing. An electro-mechanical feedback arrangement, which may include an actuator, is arranged to bear against microswitches to control operation of the motor. Different faces of the actuator are arranged to act against different ones of the microswitches in accordance with different positions of the brush bar. The height of the brush bar is selectively controllable between the predetermined positions, such that the depth of penetration of the bristles of the brush bar may be optimized for different types of carpet. | 08-19-2010 |

20100011531 | FILTER ASSEMBLY - A filter assembly for use in a cleaning appliance has filter portion and a rim surrounding the filter portion. The rim is deformable so as to be capable of sealing against a part of an appliance in which the filter assembly is located. The rim is arranged to include a locating member adapted to prevent incorrect orientation of the filter assembly in an appliance housing. The rim is flexible and capable of being manipulated and flexed by a user during a process of locating the filter assembly in an appliance. | 01-21-2010 |
20100011532 | FILTER ASSEMBLY - A filter assembly for use in a cleaning appliance has a first filter portion surrounded by a deformable rim. The first filter portion consists of a non-woven medium. The filter assembly (also includes a second filter portion located downstream of the first filter portion. The first filter portion and the second filter portion are held directly adjacent one another by means of the deformable rim. The filter assembly further includes a third filter portion located upstream of the first filter portion and consisting of a mesh material. The first filter portion and the third filter portion are held directly adjacent one another by means of the deformable rim. The filter assembly has a tab located on a surface thereof to facilitate removal of the filter assembly from a filter housing or a vacuum cleaner. | 01-21-2010 |

20090149751 | SYSTEMS AND METHODS FOR DETERMINING INTRACRANIAL PRESSURE NON-INVASIVELY AND ACOUSTIC TRANSDUCER ASSEMBLIES FOR USE IN SUCH SYSTEMS - Systems and methods for determining ICP based on parameters that can be measured using non-invasive or minimally invasive techniques are provided. Systems for acquiring acoustic data from a desired target site in a subject's body using various types of acoustic source and detector elements are also provided, including single use acoustic source/detector combinations are also provided. Acoustic arrays for use with these systems may include multiple capacitive micro-machined ultrasound transducer (cMUT) elements, and may include a combination of different types of acoustic arrays. Methods of targeting localized sites within a broad target area based on acoustic data having various properties are also disclosed. | 06-11-2009 |

20120108918 | Acoustic Palpation Using Non-Invasive Ultrasound Techniques for Identification of Target Sites and Assessment of Chronic Pain Disorders - Methods and systems for identifying and spatially localizing tissues having certain physiological properties or producing certain biological responses, such as the sensation of pain, in response to the application of intense focused ultrasound (acoustic probing or palpation) are provided. In some embodiments, targeted acoustic probing is employed to identify the scope and severity of chronically painful sensitized tissue areas, and of chronic pain disorders. In other applications, targeted acoustic probing is used to localize nerves and other sensitized tissues for guidance of needles and other delivery devices, and for delivery of anesthetic, analgesic or therapeutic compositions. | 05-03-2012 |
20140039279 | ACOUSTIC PALPATION USING NON-INVASIVE ULTRASOUND TECHNIQUES FOR IDENTIFICATION OF TARGET SITES AND ASSESSMENT OF CHRONIC PAIN DISORDERS - Methods and systems for identifying and spatially localizing tissues having certain physiological properties or producing certain biological responses, such as the sensation of pain, in response to the application of intense focused ultrasound (acoustic probing or palpation) are provided. In some embodiments, targeted acoustic probing is employed to identify the scope and severity of chronically painful sensitized tissue areas, and of chronic pain disorders.
