An article of furniture comprising a frame including a first portion disposed in a horizontal direction and having an opening centrally disposed therein and a second portion attached to an underside of the first portion and disposed in a vertical direction. A predetermined plurality of leg members are connected to such underside of the frame's first portion of said frame to maintain the frame at a desired height. A flat member having a smooth finish on one side and a cushion on an opposite side. A first device is provided to enable rotating of the flat member to expose one of such smooth finish and such cushion as desired. There is a second device provided to maintain the flat member in a substantially horizontal plane during use.

An auto-focus system employing a tunable liquid crystal lens is provided that collects images at different optical power values as the liquid crystal molecules are excited between a ground state and a maximum optical power state tracking image focus scores. An image is acquired at a desired optical power value less than maximum optical power established with the liquid crystal molecules closer a fully excited state than the maximum optical power state having the same image focus score. This drive signal employed during image acquisition uses more power than was used to achieve the same optical power value during the auto-focus scan, while actively driving the liquid crystal molecules is fast. A pause due to image transfer/processing delays after acquisition is employed to allow slow relaxation of the liquid crystal molecules back to the ground state in preparation for a subsequent focus search.

A method includes identifying a number of nodes in a network, where the nodes may correspond to cellular communication sites. The method may also include selecting some of the nodes as potential hub nodes and determining, for each of the potential hub nodes, a bandwidth needed to forward traffic from the potential hub node to a mobile switching office. The method may further include determining, for each of the potential hub nodes, bandwidths needed to forward traffic from the potential hub node to other ones of the nodes and calculating, for each of the potential hub nodes, costs or latencies associated with forwarding traffic from the potential hub node to the mobile switching office and to other ones of the nodes. The method may also include selecting a hub node based on the calculated costs and/or latencies.

The present invention provides system, method and apparatus for energizing one or more brake lights on a vehicle without an operator of the vehicle applying a brake of the vehicle by determining an acceleration of the vehicle, energizing the brake lights on the vehicle whenever the acceleration of the vehicle equals or exceeds a braking threshold, and deenergizing the brake lights on the vehicle whenever: (a) the brake lights are energized, (b) the acceleration of the vehicle is less than the braking threshold, (c) a specified period of time has elapsed since the brake lights were energized, and (d) the operator is not applying the brake of the vehicle.

A frame for an electric vehicle with a motor and a transmission, the frame including a steering head unit, a power unit casing, a left side frame and a right side frame. The steering head unit includes a steering head, a left extension and a right extension, wherein the left extension and right extension extend at an angle from the steering head. The power unit casing encloses the motor and the transmission, orienting the gearbox of the transmission vertically underneath the motor. The left and right side frames mount, on one end, to the left and right extensions of the steering head unit, respectively, wherein the other end mounts to the left and right sides of the power unit casing, respectively. The steering head unit, the power unit, the left side frame and the right side frame form an open cage, configured to accept a battery assembly.

A method and apparatus for displaying quantities of inventory items in multiple units of measure includes displaying an inventory item listing, including a desired quantity of the inventory item, on a user interface and/or display screen. The inventory item listing is then activated by a user through a user interface device within the context of the present transaction. Once the inventory item listing is activated, the quantity of the inventory item desired is displayed in a multiple units of measure display in multiple units of measure associated with the inventory item and within the context of the present transaction.

Embodiments of a method for using a microreactor to produce biodiesel. For example, the method may comprise flowing a first fluid comprising an alcohol and a second fluid comprising an oil to the microreactor. Alcohols typically, but not necessarily, are lower aliphatic alcohols, including methanol, ethanol, amyl alcohol or combinations thereof. Biodiesel production can be under supercritical conditions, where such conditions typically are determined relative to the alcohol component. Suitable sources of oil products include soy, inedible tallow and grease, corn, edible tallow and lard, cotton, rapeseed, sunflower, canola, peanut, safflower, and combinations thereof. Catalysts can be used to facilitate biodiesel production, such as metal oxides, metal hydroxides, metal carbonates, alcoholic metal carbonates, alkoxides, mineral acids and enzymes. Oil conversion to biodiesel typically increases with increasing mean microreactor residence time. Certain embodiments of the present invention can include blending biodiesel produced by the method with petroleum-based products.
摘要:
An articulated bench comprising a two-section pad and two folding/pivoting support leg assemblies attached to a frame. A length-adjustable (telescoping) dual tubular brace assembly folds out of the frame from beneath the pivoting padded section (i.e. the section for supporting the upper body) and is inserted into one of a series of catches located on the section's rear surface to hold it at a selectable incline. Improved pivoting support leg assemblies include primary foot cross-bars, and secondary foot crossbars each fixedly attached to a leg to either provide lateral floor-support when the support legs are locked in the inwardly stowed position, or alternatively serve as a hand holds or foot rests when the legs are deployed for performing exercises, thereby allowing a broader range of positions and much greater utility. Since either support leg assembly can be folded inward and locked such that the end of the frame may be inclined downward and supported on the secondary foot crossbar, the number of angular positions for the padded sections is effectively tripled.

A security device includes a plurality of security detectors intercommunicating with each other. Each of the security detectors includes a first device for verifying a single zone verification time of the respective security detector and a second device for verifying a multiple zone verification time with another security detector corresponding to a distance between two security detectors at two different detecting areas. When one of the security detectors detects at least two triggered signals in the respective detecting area within the single zone verification time, the respective security detector activates the local warning system to produce a local warning signal. When two security detectors are intercommunicated with each other to detect two triggered signals in the detecting areas respectively within the multiple zone verification time, at least one of the security detectors activates the local warning system to produce the local warning signal.

A power switching circuit is provided for use in an integrated circuit including at least a first voltage rail and a second voltage rail. The power switching circuit includes at least one MOS device having a first source/drain adapted for connection to the first voltage rail, a second source/drain adapted for connection to the second voltage rail, and a gate adapted for receiving a control signal. The MOS device selectively connects the first voltage rail to the second voltage rail in response to the control signal. The first and second voltage rails form a grid overlying the power switching circuit, the first and second voltage rails being formed in different planes relative to one another. The connection between the power switching circuit and the first voltage rail is made at an interface between the first and voltage rails.
