Abstract: An ergonomic keyboard having a mount and a plurality of keys arranged in a plurality of unbroken adjacent rows is provided. Each row is comprised of an arcuate portion, a left portion, and a right portion. The left and right portions extend tangentially from the left and right sides of the arcuate portion, respectively. The arcuate portion, of each row is convex to the user side of the keyboard, and at least two keys in each arcuate portion are elongated. Alphanumeric indicia on the keys can be arranged in the QWERTY pattern.

Abstract: The invention is a method and system for mobile communications. A mobile communicator communicates with a network routing center. The communicator monitors each of two or more wireless carriers for a service characteristic. The communicator selects, based on the monitored service characteristic, one of the two or more wireless carriers. The mobile communicator can then communicate with the network routing center using the selected wireless carrier.

Abstract: According to one embodiment of the present invention, a wavelength-shifted dynamic intelligent bidirectional access optical system utilizes key optical elements such as: a quantum dot enabled semiconductor optical amplifier, a phase modulator and an intensity modulator to provide upstream optical signals. These key optical elements reduce the Rayleigh backscattering effect on the transmission of optical signals. to enable a longer-reach access network topology between a subscriber unit and a super node (e.g., many local nodes collapsed into one super node). Such a longer-reach access network topology eliminates operational and capital costs related routers and switches. Furthermore, a wavelength to a subscriber unit may be protected and dynamically varied for on-Demand bandwidth, information and services and also a subscriber's unit may be configured with any array of connectivity options.

Abstract: An apparatus for abdominal exercise comprises a pair of laterally spaced u-shaped support rails for rocking back and forth on a surface. A pair of arm rests are each connected to the inside u-shape portion of one of the support rails and extend rearwardly from the contact point to the surface to receive an elbow of a person disposed between said rails in a supine position. A first connecting portion connects the support rails above the contact point to the surface. A second connecting portion connects the support rails behind the contact point to the surface. A plunger is connected to said first connecting portion whereby a person disposed supinely on said support surface and between said support rails and with one of the hands or arms of the person engaging said first connecting portion is able to conduct a curling exercise to exercise the abdominal muscles of the person while rocking said device, and wherein said plunger is positioned to engage a user's abdomen to provide a kinetic and isometric force.
