Abstract: A method of processing digital samples of a signal received at a receiver of a wireless communication system includes monitoring channel conditions and generating a channel indicator including at least one channel parameter by performing at least one of: estimating a channel mobility parameter and comparing it with a threshold; estimating a channel parameter of the energy of the channel outside a predefined temporal window, and comparing it with a threshold; estimating a channel temporal duration parameter and establishing if it meets predetermined criteria; estimating a channel-zero location parameter and establishing if it meets predetermined criteria; estimating a received-signal signal-to-disturbance power ratio, and comparing it to a threshold; estimating an estimated-channel-response signal-to-disturbance power ratio; estimating the degree of non-stationarity of the disturbance at the receiver input; and selecting one of a plurality of processing routines for processing the digital samples based on said

Abstract: A work bench support bracket with first and second opposed, generally upright sockets for receiving wood members is joined to first and second telescopically interconnectible, generally horizontal sockets, respectively. First and second clamping sets are also joined to the first and second generally upright sockets, respectively. Each of the clamping sets comprises an upper releasable chimp and a fixed lower brace member. The upper releasable clamp comprises a grip pivotably attached to the upright socket, a connector extending from the grip, and a handle pivotably connected to the connector. The work bench support bracket provides for the secure attachment of the wood members and reduces the likelihood of an accidental release of the wood members.

Abstract: Techniques are described for optimizing the processing facilities of a receiver in a wireless communication environment, taking into account processing performance set against the computing resources and/or power consumption required to obtain that processing performance. A radio receiver for a wireless communications system can include channel equalization means arranged to receive samples of an incoming signal and to generate an equalized output, said channel equalization means including means for processing said digital samples in accordance with an equalizer algorithm. The receiver includes means for estimating parameters of a channel over which the incoming signal has been transmitted. The receiver can also include means for selecting from a plurality of equalizer algorithms an equalizer algorithm for execution by the processing means based on at least one said estimated channel parameter. Related methods and algorithms are described. Related computer program products are also described.

Abstract: A handrail assembly comprises an elongated railing and a plurality of brackets. The railing has two lateral channels extending along its length and a central member extending between the two lateral channels. At least one of the brackets has a base and two prongs extending away from the base. Each of the prongs engages one of the lateral channels. The engagement of the railing with the brackets forms a cavity that is defined, at least in part, by the central member, the base, and the prongs.

Abstract: A gate bracket is formed of a planar web in which two rectangular portions along two edges of the web are bent to define a first pair of perpendicular flanges, and two other rectangular portions are bent from an inner portion of the web to form a second pair of perpendicular flanges. The flanges of the first pair are spaced from the flanges of the second pair by a distance corresponding to the dimensions of the structural members used to construct the gate. The invention provides a rigid bracket of simpler and lighter construction than prior art brackets.

Abstract: A rain gutter guard comprises a downward leg for abutting gutter hangers when the guard is urged down into the gutter. A shoulder of the guard accommodates the shoulder of the gutter hangers. A front attachment flap secures the front of the guard to the gutter while the rear is retained by friction fit of an angled segment against the building fascia. An upstanding wall separates the central portion from the attachment flap. The central portion is inclined rearward and the attachment flap inclines to the front.

Abstract: A post anchor for securing a support post for a structure comprises a base with four upstanding sidewalls forming a cavity into which a post is inserted, and means to secure the post inside the cavity. Interior ribs and exterior augmented corners resist deformation under pressure exerted by the post. Interior channels allow water to drain from inside the cavity toward a drain hole. The anchor post is slightly elevated relative to the ground, allowing air and water to circulate around the post and post anchor. The post anchor is made of a thermoplastic polymer which is given a textured surface, and may include an ultraviolet protection additive.

Abstract: A bracket for attaching a post to one or more fascia boards is provided. In one embodiment, the bracket comprises a flat top surface with openings sized to receive fasteners for attachment to the post. A back surface comprises openings sized to receive fasteners for attachment to the fascia boards. Two flanges extend substantially perpendicularly to both the top surface and the back surface. A cover is releasably attachable to the flanges. In another embodiment, the bracket comprises a top surface, a plurality of walls extending down from the top surface, and a plurality of angled faces extending from an edge of the walls. The top surface, the walls, and the angled faces form a semi-enclosed space.

Abstract: A picket for a railing system comprises an elongated body with one or more walls and first and second ends. The first and second ends engage the top and bottom rails, respectively, of the railing system. The picket also comprises one or more cutouts formed along one or more of the walls. Each of the cutouts engages one of the plurality of spacers. The cutouts are proximal to the first and second ends of the pickets.

Abstract: A magnetic resonance imaging (MRI) method of investigating tissue fluid velocity in a region of interest comprising substantially eliminating the magnetic resonance signal of blood flowing in one or more blood vessels in the tissue by applying a nulling preparation to the tissue; and deriving the interstitial fluid velocity using magnetic field gradients.

Abstract: A butterfly valve is described which comprises a valve disc located within a flow passage provided in a housing and engageable with a seat provided within the housing, the valve disc and housing cooperating with one another, when the valve disc occupies a closed position, to define an annular void extending around the periphery of the valve disc at a position spaced from and independent of the main valve seat, an inlet port and an outlet port communicating with the void to allow the supply of sealant to the void to form a seal between the valve disc and the housing.
