The present packet scheduling algorithm gives cellular network operators greater flexibility in adjusting the way resources are allocated among interactive best-effort data users. Best effort data users with different radio link qualities may have different amounts of data delivered to them using the same amount of radio resource. In the context of link adaptation, this characteristic complicates the fairness issue in cellular environments and has a profound impact on the overall system performance. As a result, the present packet scheduling algorithm is capable of allocating radio resource dynamically, not only based on channel conditions, but also to achieve different performance trade-offs among users with different link qualities. According to the algorithm, channel quality is determined for each user, channel efficiency is calculated and the channel efficiency value is used as the primary factor in weighting the delivery of packets to (or from) a given user. In a packet schedule weighting equation, a value of exponent may be varied from negative to positive to give good (or bad) users better service. However, performance of users with bad channel qualities degrades the performance of good channel users in a disproportionate manner. It is shown that it is frequently preferable to favor users with good channel qualities.

A spacer for delivering a medication spray from an inhaler includes a first conical body joined to a second conical body, forming a continuous spray conduit through first and second internal chambers of the respective first and second conical bodies. A mouthpiece is formed in the proximal end of the first conical body. A spray inlet for attachment to the inhaler is formed at the distal end of the second conical body. A plurality of air inlets are placed downstream of the medication inlet proximate to, or in, the large diameter distal end surface of the first conical body. Recirculation zones are created in the first and second chambers, to force the medication spray into a central airflow path through the spray conduit, minimizing particle deposition by contract with the walls of the spacer.

A cutter clip and methods for installing a gutter cover onto a gutter system are disclosed. The gutter clip includes a mouth portion sized to provide an interference fit between the gutter cover and the mouth portion of the clip which stationarily secures the gutter cover to the gutter clip. The gutter clip is further provided with a mounting portion that fastens to the lip of a gutter. Once assembled, the gutter clip of the present invention provides minimum horizontal and vertical tolerances between the gutter and the gutter cover, such that water may flow freely into the gutter channel, but does not permit debris to be lodged therein.

A method for communicating in a wireless local area network. The method according to one embodiment includes transmitting, by a first station, a plurality of a request to send (RTS) frames to a second station through a plurality of subchannels; receiving, by the first station, at least one clear to send (CTS) frame; and transmitting, by the first station, a data frame to the second station. If the at least one CTS frame includes channel information indicating all of the at least one idle subchannel through which the at least one CTS frame is transmitted, the data frame is transmitted via the at least one idle subchannel indicated by the channel information, and if the at least one CTS frame does not include the channel information, the data frame is transmitted via at least one of the plurality of subchannels indicated by the plurality of RTS frames.

A gearset includes a gearset housing, a drive shaft, and a radial fan fixed to the drive shaft. Disposed in surrounding relationship to the radial fan is an air-guiding cover which includes a gearset housing section to at least partially cover the gearset housing, a cylindrical section adjoining the gearset housing section and configured to receive an attachment for securement to the drive shaft, and a conical section adjoining the cylindrical section. The conical section of the air-guiding cover is disposed in surrounding relationship to the radial fan directly and without any dead space.

A refrigerated product merchandising unit for storing and displaying chilled products including a body member, a product holding container positionable within the body member, and a base member having a refrigeration unit associated therewith, the refrigeration unit being positionable within the body member and being adapted for providing cold air to the product holding container. The product holding container includes a first plurality of openings positioned adjacent the top end portion thereof for allowing cold air to enter the product holding container and a second plurality of openings positioned adjacent the bottom end portion thereof for allowing air to exit the product holding container for recycling through the refrigeration unit. A member is provided for segregating air exiting the product holding container from the cold air being delivered to the product holding container such that air exiting the product holding container cannot be redirected to the first plurality of openings without first passing through the refrigeration unit.

A method (100) of forming a silicon-on-insulator (SOI) wafer includes forming one or more channels in a top surface of a first wafer (104), and forming an insulator layer on a second wafer (106). The second wafer is treated (108) to generate a structural weakness therein, and the first and second wafers together (110) are then bonded together so that the channels face the insulator layer. A portion of the second wafer is then removed (112) from the bonded first and second wafers at a location corresponding to the structure weakness.

A cap includes a flexible body having a dome shape for conveniently conforming to a swimmer's head. The body includes an outer layer and an inner layer spaced from the outer layer such that a cavity is defined therebetween. The inner layer is provided with a plurality of conduits and a strap is integral with the outer layer and travels about a circumference of the cap. The present invention further includes a mechanism for effectively removing the stagnant air such that the inner layer can effectively maintain surface contact with the swimmer's hair and cooperate with the strap for preventing water from entering beneath the cap.

A micro-relay that overcomes some of the limitations and drawbacks of the prior art is disclosed. The micro-relay comprising: (1) a first substrate comprising one or more monolithically integrated planar coils for generating a magnetic field; and (2) a second substrate comprising a magnetically actuated switch having a moving contact that selectively moves in a plane parallel to its substrate. The first and second substrate are aligned and bonded to collectively provide a closed magnetic circuit that efficiently channels the generated magnetic field through the switch.

An apparatus and method for droplet steering is disclosed herein. A throated structure having a nozzle defines a converging throat with an inlet and an outlet and a vectored fluid stream directed therethrough. The fluid stream is driven through the system via a vacuum pump. As the fluid approaches the outlet, its velocity increases and is drawn away from the nozzle through a connecting channel. As a droplet is ejected from a liquid therebelow, it will have a first trajectory until it is introduced to the high velocity fluid stream at the perimeter of the interior walls of the nozzle. The fluid accordingly steers the momentum of the droplet such that it obtains a second or corrected trajectory. Alternative variations include an electrically chargeable member, e.g., a pin, positionable to be in apposition to the outlet and capillary tubes for controlling the ejection surface of the pool of source fluid.
