A cambering vehicle for human propelled transport comprises an elongate front column, first and second pivot axles at the front column, a first trailing arm pivotally attached to the first pivot axle, a second trailing arm pivotally attached to the second pivot axle, a front ski associated with the elongate front column, and, first and second rear skis associated with said first and second trailing arms. The first and second pivot axles may be inclined downward. Separately, a ski may be adapted for attachment to a conventional cambering vehicle having a front tube with a fork, where the ski comprises a surface having a rear section, mid-section, and front section, the surface being relatively flat at its rear section and mid-section, but curving upward at its front section, and an attachment mechanism for attachment to the fork.
摘要:
A differential mobility analyzer (DMA) for separating charged particles or ions suspended in a gas and a method of using the DMA for separating such particles. The invention includes various means for increasing the resolution of the DMA by stabilizing the laminar flow within the DMA and by allowing unusually large flow velocities.

Side-reading of an abutted-junction magnetic transducer is measured by constructing at least one microtrack having a transition density. The transducer is moved relative to the microtrack to identify a plurality of positions of the transducer relative to the microtrack where the transducer provides a predetermined response. The side-reading distance of the transducer is identified from the plurality of positions. In one embodiment, a plurality of microtracks are constructed during different iterations, each having a different transition density, and the positions of the transducer are identified during each iteration relative to the respective microtrack. In another embodiment, the selected transition density has a fundamental frequency, and the position of the transducer is identified relative to the microtrack where the transducer provides the predetermined response at each of a plurality of harmonic frequencies of the fundamental frequency.

An improved container is provided for cooking eggs and the like in a microwave oven. The container includes a bottom cup having a top opening and a top cap configured to fit over the top opening. The container can also include a unique separator fitted within the bottom cup. The separator can include a cracker plate for cracking egg shells and/or at least one depending leg extending along an inside surface of the bottom cup to facilitate separation of cooked eggs. The container can also include a unique scrambler fitted within the top cap. Preferably, the scrambler is formed as a grid through which egg contents can pass when the container is shaken. In addition, a novel cradle can be provided to facilitate carrying and handling of a plurality of like containers. The preferred embodiments of the present invention enable a variety of egg dishes—e.g., poached eggs, scrambled eggs, omelets, etc.—to be easily and conveniently cooked in microwave and the like ovens with added health benefits, e.g., not requiring added fats or the like, and other advantages.

An analytical apparatus provides for the separation and analysis of a subset of ions from a mixture of ions in a gas. The apparatus includes an ion supply, such as an electrospray, which provides a population of variously charged ions. An analyzing chamber is coupled to the ion supply and includes a first wall with an inlet orifice for receiving the flow of variously charged ions, and a second wall opposed to the first wall. A laminar gas flow is established within the analyzing chamber along a flow axis. The second wall is provided with an outlet orifice that is displaced by a determined distance along the gas flow axis from the inlet orifice. A potential difference is applied between the first and second walls which causes the flow of ions, introduced via the inlet orifice, to migrate towards the outlet orifice. The laminar gas flow displaces ion flight trajectories along the flow axis, so that only the ions with a mobility near a specific value reach the second wall close enough to the outlet orifice to be sampled through it. The outlet orifice is coupled to the inlet of a mass spectrometer to enable analysis of the ions emerging from the outlet orifice.

A current limiter component constituted by a semiconductor bar or wafer doped in four layers (P, N, P, N) between its anode and cathode. The doping characteristics and the dimensional characteristics of the bar are adjusted to obtain a characteristic current to voltage curve which initially increases as voltage and current increases in the manner of a diode followed by a part constituting a current limiting plateau wherein the plateau reflects that the current remains fixed until the voltage reaches a breakdown voltage.

An apparatus and method for pixel hashing. For example, one embodiment of a method comprises: determining X and Y coordinates for a pixel block to be processed; performing a lookup in a data structure indexed based on the X and Y coordinates of the pixel block, the lookup identifying an entry in the data structure corresponding to the X and Y coordinates of the pixel block; reading information from the entry identifying an execution cluster to process the pixel block; and executing the pixel block by the execution cluster.
摘要:
A rapid method of volatile analysis and interpretation is taught enabling inferences on the surrounding environment as sophisticated as commonly achieved by dogs via olfaction. The method is based on rapid analysis of vapors released by persons or other organisms into a gas, correction of said analysis due to competing ambient volatiles, extraction of abundance patterns of certain preselected metabolites present in said vapor analysis, and classification of said persons or organisms by comparison of said abundance patterns with preestablished standard metabolite patterns. A preferred approach for rapid analysis involves an atmospheric pressure ionization, such as an electrospray cloud, followed by a mass spectrometer with an atmospheric pressure source. A preferred method for background correction is subtraction of the background signal from the sample signal when both are ionized at similar humidity levels. A preferred comparison pattern involves the abundance of fatty acids and other common metabolites. Preferred classification criteria include recognition of individuals, or species, or health state.
