A mower and an attachment device or mount having a frame attachment clamp to removeably affix to the wheel support frame, a pivotable linkage arrangement to position a string trimmer proximate either front wheel of the lawnmower, and a grade wheel to maintain a designated height of string trimmer above grade. The attachment device or mount may enable the operator to attach the frame attachment clamp to either front wheel enabling the operator to look ahead and anticipate where the lawnmower needs to be driven and simultaneously to position the string trimmer for trimming and edging operation around landscapes and borders on either the left or right side of the lawnmower.

One apparatus for providing high-resolution CSI feedback includes a processor and a radio transceiver. The processor computes sets of amplitude and phase parameters for one or more matrices corresponding to a CSI codebook. Here, each matrix corresponds to one transmission layer of a multiple-layer transmission, where each matrix is comprised of one or more column vectors. The radio transceiver sends indications of the sets of amplitude and phase parameters to one or more network entities is a mobile communication network.

A network of modular, multitier pool mobile units, that wander around and under water of a swimming pool. The pool mobile units monitor for safety, emergency and accident related events and undertakes appropriate actions, scrub and clean the swimming pool, emit chemical agents to sanitize the swimming pool water, and may play music. The pool mobile units may simply operate on the pool surface, be fully submersible, or semisubmersible. A central server manages a plurality of multitier pool mobile units in a plurality of swimming pools, supports music download, and provides experience based resources for the multitier pool mobile units. The central server provides experience based resources in the form of safety, emergency and accident supports. The user can configure the parameters of both pool mobile unit and the central server.

A device for extracting auxiliary power from a power source installed on or associated with an implement, and supplying the auxiliary power to an auxiliary tool associated with the implement. The invention is preferably employed in the context of an auxiliary tool, e.g., in the form of a rotary trimmer, edger or the like, associated with another power implement, such as a lawnmower, wherein the power is preferably extracted from a driven member of the implement. Advantageously, the device is easy to attach/detach, is universally locatable and/or orientable on the implement, and is easily retrofittable to practically any existing implement, such as a lawnmower deck.

Vehicle-mounted line trimmers and/or edgers for weed and vegetation, along with methods of operation of such trimmers, are discussed. The trimmer/edger can have a variety of features such as maintaining and/or adjusting the height of the trimmer/edger and maintaining the same orientation of the trimmer/edger at a variety of heights. The methods of operation can include methods for recording a path for the trimmer/edger and/or following a pre-recorded path for the trimmer/edger, trimming/edging around small obstacles, and trimming/edging along large obstacles.

A lawn mower (100) comprising a wheeled carriage (102) configured to carry a primary cutting tool (105) for cutting lawn, the primary cutting tool (105) being operably coupled to a primary drive system. The mower (100) also comprises a trimmer (106) operably coupled to the wheeled carriage (102), and a translation mechanism comprising a selectable static state and a selectable dynamic state. The translation mechanism (110, 112, 114, 116, 118, 120) is operably coupled to the trimmer (106) and configured to permit horizontal translation of the trimmer (106) in front of the wheeled carriage (102) in response to selection of the dynamic mode.
